▼ La notion du développement de l’Afrique est essentiellement liée à son histoire, et particulièrement à celle des indépendances. Les peuples d’Afrique espéraient que l’accession à l’indépendance politique, allait suivre une indépendance économique, synonyme du développement humain. Mais tel ne fut pas le cas. A son tour, l’éducation, au lieu de former des personnes capables d’apporter leur savoir être et leur savoir faire à la construction d’une société juste pour le développement, elle s’est contenté d’importer la forme scolaire occidentale et de mettre en place des politiques économiques libérales. Aujourd’hui, il n’est plus question de reprendre ce chemin. Le développement n’aura aucun sens s’il n’est pas solidaire, authentique et intégral. Ce travail s’inscrit dans une démarche consistant à construire une version authentiquement africaine du développement. Celle-ci est indissociable d’une philosophie de l’éducation pour l’Afrique, dont l’exploitation et la construction seront les objectifs de cette thèse. Un penseur s’est déjà engagé sur cette voie : c’est Jacques Maritain. En s’opposant à une philosophie libérale de l’éducation, il a ouvert les perspectives d’une éducation au développement solidaire. Dans le contexte de l’Amérique latine, un autre penseur et pédagogue, Paulo Freire, a réfléchi sur un paradigme éducatif alternatif. La recherche d’une nouvelle philosophie éducative pour l’Afrique passe par l’étude comparative de ces deux auteurs contemporains.
The notion of the development of Africa is primarily tributary to its history and specifically to that of its independence. The African people expected that the accession to political independence would be followed by the economical independence that is instrumental in human development. The African Educational system has imported the western education prototype and has put in place free market policies instead of training/educating/moulding individuals capable of contributing with their intellectual and practical knowledge towards the making of a fair society that enhances development. To date, it is out of question to stick to this model. Development will not have any meaning if it is not genuine, showing solidarity and inclusiveness. This work is intended to conceive a typically genuine African model of development. This is ultimately linked /inseparable to the African philosophy of education whose concerns and making will constitute the objectives of this thesis. A philosopher, Jacques Maritain has already explored that possibility. While opposing the liberal education system, he has opened prospects to education for [development that shows solidarity /communal development] . Within Latin America’s context, another philosopher and educationist, Paulo Freire, has considered an alternative education paradigm. The search for a new philosophy of education for Africa is tributary to the comparative study of these two contemporary scholars.

▼ Clinical uses for assaying nerve somatotopy or continuity could benefit from more detailed mappings than current methods offer. In the present study, the efficacy of using the Utah Slanted Electrode Array (USEA) to assay nerve resomatotopy in a fast, detailed, and quantitative manner was tested. Feline tibial nerve at the ankle (TNA) and superficial peroneal nerve (SPN) branches were stimulated with bipolar electrodes at the ankle. The resultant compound action potentials (CAPs) were recorded from a USEA implanted in the sciatic nerve. Results from eight preparations showed that somatotopy of the nerve could be distinguished using the recordings with the USEA. This approach was fast, monitoring 100 sites within the nerve simultaneously. The results were quantitative, with CAP amplitudes from one stimulus being twice the CAP amplitudes from the other stimulus in distinct areas. This method was also very eproducible, showing the same somatotopy both within a preparation and among preparations: TNA stimulation consistently evoked a larger response at the posterior side of the nerve, whereas SPN stimulation evoked a larger response at the anterior side of the nerve. The ability of the USEA to record from small groups of cutaneous afferents was examined by cutaneous, bipolar stimulation of skin innervated by the TNA and SPN branches. Cutaneous stimulation of the dorsal surface of the paw evoked a recorded response at the anterior side of the nerve, whereas stimulation of the plantar surface was recorded at the posterior side of the nerve. This result was expected, because the SPN innervates the dorsum of the paw and the TNA innervates the plantar surface of the paw. Musculotopy of the sciatic nerve was also examined by stimulation through the USEA of the sciatic nerve. The resultant musculotopy map showed activation of muscles innervated by the peroneal nerve by stimulation through electrodes implanted at the anterior of the nerve. Muscles innervated by the tibial nerve were activated by stimulation through electrodes implanted at the posterior of the nerve. This result showed that the somatotopy map was similar to the musculotopy map. The documented ability to record nerve CAPs with USEAs may provide novel opportunities for research investigations and clinical applications. v

▼ Influenza virus is a respiratory infection of
public health importance, because it is associated with a
substantial burden of morbidity and mortality in Hong Kong and
elsewhere. The traditional paradigm suggests that influenza virus
transmits between humans primarily by respiratory droplets and
secondarily by contact, while there is controversy over the role of
aerosol transmission. Interventions to control influenza epidemics
often require identification of infected persons, which is
challenging without laboratory testing, while asymptomatic
infections may have a role in community spread.
I conducted a
series of studies on the potential contribution of aerosols to the
transmission of influenza, the efficacy of surgical face masks
against aerosols, the potential for a new rapid test to be used for
the identification of cases of influenza virus infection, and the
potential importance of asymptomatic infections in the spread of
influenza epidemics. In one study, I used a Gesundheit-II (G-II)
device to collect exhaled breath particles from outpatients in two
size fractions, ≥5μm (coarse) and <5μm (fine) and maintained
viability of any viruses collected in the fine fraction. In a
second study, I used a cyclone NIOSH air sampler to detect
influenza virus in fine particles in patient rooms. In the third
study, I used data from three separate studies of outpatients to
characterize the clinical diagnostic performance of the Sofia
Influenza A+B Fluorescent Immunoassay. Finally, I conducted a
systematic review and meta-analysis of published estimates of the
proportion of influenza virus infections that are asymptomatic.
In the first study, I showed that influenza A virus, including
A(H1N1)pdm09 and A(H3N2), were found in both fine and coarse
fractions of exhaled breath particles. I also showed that wearing a
surgical face mask led to a significant and substantial reduction
in influenza A virus shedding in the coarse fraction of exhaled
breath. In the second study I detected influenza virus RNA in
aerosols at low concentrations half of the time in patient rooms
with patients with confirmed influenza virus infection. I estimated
that the sensitivity and specificity of the Sofia rapid test for
detection of influenza A and B were 77% (95% CI 71-82%) and 91%
(95% CI 89-92%) respectively. In the meta-analysis I found that
estimates of the asymptomatic fraction were affected by study
design, with estimates from outbreak investigations having a pooled
mean of 16% (95% CI: 13%, 19%), while estimates from cohort studies
adjusting for incidence of non-influenza illnesses fell in the
range 65%-85%.
Influenza virus could be detected in fine
particles in the exhaled breath of outpatients with influenza, and
in the rooms of inpatients with confirmed influenza, supporting a
role of aerosol transmission in the spread of influenza in the
community. The Sofia rapid test had higher sensitivity than other
point-of-care tests, but poorer specificity leading to a low
positive predictive value outside of peaks in influenza activity.…

▼ Influenza viruses cause a substantial burden of
morbidity and mortality worldwide. Household studies have been used
to study the epidemiology of influenza for decades. One more recent
development is the use of household transmission studies with
short-term follow-up rather than following up over an entire
season.
Using data from household transmission studies done in
Hong Kong, I explored the role of two biological variables on
transmission, specifically antibody titers measured by
hemagglutination-inhibiting (HAI) or microneutralization (MN)
assays and viral shedding measured by reverse-transcription
polymerase chain reaction (PCR) test on nose and throat swabs. To
explore the relationship between antibody titers and protection, I
used individual-based hazard models that can account for the
household transmission dynamics. I developed a Bayesian Markov
chain Monte Carlo (MCMC) algorithm to impute the missing antibody
titers and estimate the model parameters jointly. To explore the
relationship between viral shedding and infectivity, I first fitted
a log-linear random effects censored regression model to
reconstruct the individual viral shedding trajectory to overcome
missing observations of viral shedding. Then I extended the
abovementioned household transmission model to incorporate with
data on viral shedding to compare the consistency between pattern
of viral shedding and timing of secondary infection in households.
I discovered that an HAI titers of 1:40 against seasonal influenza
A(H1N1) and A(H3N2) viruses were associated with 31% (95% CI: 13%
to 46%) and 31% (CI: 1% to 53%) protection respectively, which were
much lower than 50% protection in other settings. I also
demonstrated the association between MN titers and protection. The
pattern of viral shedding trajectories was not particularly
consistent with the timing of secondary infection and individual
viral shedding was at most weakly associated with individual
infectivity.
To estimate the cumulative risk of infection of 2009
pandemic influenza virus outbreak from a separate community-based
cohort study with multiple sera collections, I developed a Bayesian
hierarchical model to account for the timing of sera collection and
missing of sera collection in the study. I found that using all of
the collected sera in the analysis could substantially improve the
precision of estimation, compared with a simple analysis that only
used the proportion of 4-fold or greater rise in participants as
estimates.
The association between an HAI titer of 1:40 and
protection was substantially less than 50% in households, perhaps
due to the intense and frequent contacts between persons in
households. Viral load measured by RT-PCR in the nose and throat
was as most weakly correlated with individual infectivity in
households, and other correlates of infectivity should be examined
in future studies. The statistical framework that I developed to
account for the timing of sera collection can provide robust
estimates of cumulative risk of infection during an…

▼ Background The dynamics of influenza virus
transmission are not yet fully understood, hindering the
appropriate development and implementation of control and
mitigation strategies. One major uncertainty relates to the profile
of infectiousness over time in humans infected by influenza virus,
and how variation in infectiousness might contribute to the risk of
transmission in households.
Methods In 2008 and 2009, two large
community-based studies were conducted to study the household
transmission of influenza viruses in Hong Kong. I analyzed data on
viral shedding and disease in participants, and used statistical
models to examine how viral shedding patterns and other factors
might affect the risk of influenza virus transmission in
households, both within individuals over time, and between
individuals with different patterns in viral shedding.
Results
The patterns of viral shedding relative to the time of illness
(acute respiratory illness; ARI) onset in naturally acquired
infections were found to be largely comparable to the patterns
observed in experimental infections. Viral shedding detected by
RT-PCR peaks around the day of ARI onset after which levels of
shedding declined over around 7 days, and viral shedding tended to
be greater in children than adults. The patterns of viral shedding
in cases of seasonal A subtypes were similar, although the trends
of shedding in cases of seasonal B differed with some indication of
a plateau in shedding for up to 5 days after illness onset. The
risk of household influenza transmission was significantly
associated with log10 viral shedding, though not with influenza
related signs and symptoms such as cough.
Conclusions The
patterns of viral shedding observed in naturally-acquired influenza
A virus infections correlated with the pattern of infectiousness
over time after onset of illness. The majority of infectiousness
was estimated to occur within 2-3 days of illness onset, with
implications for isolation strategies. The heterogeneous nature of
individual viral shedding suggests the possibility of substantial
variation in infectiousness, particularly among
children.

▼ Dopamine is required for normal behavior and cognition and defects in dopamine signaling underlie schizophrenia and Parkinson's disease (Van Os et al., 2009; Kalia et al., 2015). Dopamine is one of the most extensively studied neurotransmitters, yet we still do not have a complete picture of how it functions within the nervous system. The basic textbook diagram of a neuron synapse portrays neurotransmitter being released from vesicles at the synapse, traveling across the synaptic cleft, and binding neurotransmitter receptors on the surface of the post-synaptic neuron. However, for neurotransmitters like dopamine and serotonin, that do not directly initiate action potentials but rather modulate neuron excitability, receptors are not restricted to post-synaptic sites but can be found throughout the neuron including on dendrites, soma, and at presynaptic locations (Zhang et al., 2016; Zussy et al., 2016). The effects of these types of receptors on neural activity are difficult to measure as neuron activity is measured at the soma. Such measurements can reveal effects of receptors located upstream of the recording instrument including at the soma or in proximal dendrites but they can not measure changes in neural activity caused by receptors located at presynaptic sites. The effects of these presynaptic receptors must be measured in downstream, synaptically connected cells. To gain a better understanding of the cellular mechanisms of dopamine receptor signaling we study dopamine's effects on the excitability of the ASH chemosensory neuron in C. elegans. ASH excitability is modulated by dopamine acting through the D1-like dopamine receptor DOP-4 (Ezcurra et al., 2011). We have used GCaMP3, a genetically-encoded calcium sensor, to measure dopamine effects in ASH by measuring changes in GCaMP3 fluorescence at the soma and we have not observed any dopamine-dependent changes. In addition, our preliminary localization studies suggest that DOP-4 is concentrated in the axon of ASH where synapses are found. These results suggest that DOP-4 may act at presynaptic sites in ASH. To measure the effects of DOP-4 signaling at these presynaptic sites we have generated cell-specific transgenes that drive GCaMP3 expression in the neurons postsynaptic to ASH. Once these transgenes are expressed in the worm, calcium recordings will be used to measure dopamine effects on neural excitability.

▼ Le développement de matériaux piézoélectriques innovants pour la réalisation de transducteurs, de capteurs ou d'actionnneurs nécessite la mise en oeuvre de dispositifs de caractérisation performants. Dans ce contexte, ce document propose des méthodes de modélisation de la propagation d'ondes ultrasonores dans des structures multicouches ou a gradients continus de propriétés. Au préalable, deux méthodes de caractérisation, ont été exposées et appliquées à des céramiques de type PZT. L'une d'entre elle, appelée méthode de spectroscopie de transmission, utilise une mise en forme matricielle de l'équation de propagation des ondes accoustiques. Cette formulation analytique facilite la résolution de l'équation de propagation, et permet également une représentation des phénomènes de transmissions d'ondes à travers une structure. La validité de ces modèles est clairement établie à travers des hétérostructures piézoélectriques.
The developpement of innovative piezoelectric materials for achievement of transducers, sensors or actuators requires the implementation of hight performance of characterization method. In this context, this document proposes two methods modeling the ultrasonic wave propagation in multilayered structures and continutes graded materials. Prior, two models of characterizations were presented and applied for PZT ceramics. They use a matrix formalism of the equation of accoustic waves. This analytical formulation facilitates the resolution of the propagation equation of propagation, and facilitate the representation of the phenomena of wave transmission through a structure. The validity of these models is clearly established through comparisons of results from finite element and measurement in piezoelectric heterostructures.

▼ Many biological systems providing very high heat and mass transfer rates in organs such as brain, liver, and lungs use microchannels and minichannels. A few years back transport in small channels gained ground due to the high heat transfer rates. Since then a lot of research has been done on heat transfer in microchannels both experimentally and numerically. The analysis done minichannels is mainly experimental and very less literature exists on numerical analysis done on heat transfer in minichannels. Some work that exists, considers short channels with aspect ratios in the range of 0.3 to 0.5. Moreover, the work done prior to this work considered considerably lower imposed heat fluxes. The experimental work done on minichannel heat sinks also considers short sinks with heat flux in the order of 40kW/m2. Hence, in this study the focus is on minichannels with an aspect ratio of the order of 0.01 and with very high heat flux imposed, of the order of 700 kW/m2. The analysis is done for three as well as two-dimensional channels. Three different channels of height 1 mm, 2 mm and 3 mm are analyzed and the results of the analysis are studied. The pressure drop across the heat sink is also reported. The temperature drop across the heat sink is reported and found to be minimum for the channel with height 3 mm for a three-dimensional channel.

▼ Cette étude de cas qualitative pose de nombreuses questions théoriques et managériales dans la cadre de la recherche sur les entreprises familiales. Elle a la particularité de se dérouler sur une période de quatre années durant laquelle, un chercheur a pu vivre au coeur de l’organisation au quotidien à travers une approche ethnographique en utilisant la technique de l’observation participante. Ce dispositif méthodologique de recherche, rare et original, a permis d’être au plus près du terrain, permettant ainsi de confronter des éléments issus de la littérature organisationnelle consacrée aux entreprises familiales et les réalités quotidiennes d’une entreprise familiale qui vit un processus de transmission. Cette étude de cas aura permis au chercheur de vivre une étape clé du processus de transmission, celle de la transmission managériale. En d’autres termes, il s’agit de la transmission par le fondateur du leadership et du pouvoir managérial aux potentiels successeurs familiaux issus de la 2nde génération. Nous cherchons à comprendre comment des construits essentiels comme la confiance et la psychological ownership peuvent influencer les comportements des parties prenantes (membres familiaux et non-familiaux). En analysant les antécédents et les conséquences comportementales et attitudinales de ces deux construits principaux, et en les confrontant aux enjeux liés à cette entreprise familiale du Moyen-Orient, nous avons pu identifier les facteurs organisationnels, institutionnels et culturels qui impactent le processus de transmission.
This qualitative case study poses many theoretical and managerial questions in the context of research on family businesses. It has the distinction of taking place over a period of four years during which a researcher could live at the heart of the organization on a daily basis through an ethnographic approach using the participant observation method. This rare and original method of research has allowed him to be closer to the field, thus enabling the confrontation of family business literature and the daily realities of a family business experiencing a succession process. This case study has allowed the researcher to experience a stage in the succession process, that of managerial succession. In other words, it is the transmission by the founder of leadership and managerial power to potential family successors from the 2nd generation. We seek to understand how essential constructs such as trust and psychological ownership can influence the stakeholders’ behaviors (family and non-family members). By analyzing the antecedents as well as the behavioral and attitudinal consequences of these two main constructs, and by confronting them with the stakes related to this Middle Eastern family business, we were able to identify the organizational, institutional and cultural factors which impact the process of succession.

▼ En la presente tesis se efectúa un estudio del comportamiento térmico de tableros de puente a partir de los datos de su geometría, para lo cual es preciso definir una clasificación de los tableros de puente a efectos térmicos. Se introducen como condiciones de contorno los datos de la temperatura ambiente y radiación a lo largo del día. Para resolver la conducción de conducción de calor se han creado dos programas de ordenador que permiten obtener el campo de temperaturas en el tablero y se ha efectuado el consiguiente estudio paramétrico de los variables que influyen en el problema. Se propone una modificación del sistema de obtención del diagrama momentos-curvatura que considere el estado de auto tensión térmica.

▼ It is unresolved whether recently transmitted human immunodeficiency viruses (HIV) have genetic features that specifically favour their transmissibility. To identify potential “transmission signatures”, we compared 20 full-length HIV-1 subtype C genomes from primary infections, with 66 sampled from ethnically and geographically matched individuals with chronic infections. Controlling for recombination and phylogenetic
relatedness, we identified 39 sites at which amino acid frequency spectra differed significantly between groups. These sites were predominantly located within Env, Pol and Gag (14/39, 9/39 and 6/39 respectively) and were significantly clustered (33/39) within known immunoreactive peptides. Within 6 months of infection, we detected reversion-to-consensus mutations at 14 sites and potential CTL escape mutations at seven. Here we provide evidence that frequent reversion mutations probably allows the virus to recover replicative fitness which, together with immune escape driven by the HLA alleles of the new hosts, differentiate sequences from chronic infections from those sampled shortly after transmission.

▼ At the heart of the field of photonics is the control of the reflection and
transmission of light. Plasmonics looks at this problem of control of electromagnetic radiation in the context of surface plasmon polaritons (SPP). SPPs are propagating electromagnetic modes localized at the interfaces between media with positive and negative permittivities. Their excitation can accompany the enhancement of
transmission, reflection, or absorption of EM radiation. There are a number of ways to excite SPPs and this work looks at several geometries and analyzes the
transmission and reflection characteristics using a numerical approach based on the finite element method.
The first method of excitation is by incident evanescent wave that was totally internally reflected from an earlier interface. It is shown that an evanescent wave can excite SPPs and create resonant transmisison. It is also found that high values of dissipation limit
transmission and instead create resonant absorption. The second method involves the modulation of the negative permittivity of the plasma slab itself. Numerical results are compared to analytical ones and are in good agreement because harmonics of the solution above the first are negligible. An investigation of
transmission through a plasma slab with a single thin diffraction grating placed nearby follows. Analytical and numerical calculations show that a single thin grating is sufficient to create
transmission resonance. It is found that for large values of diffraction grating modulation parameter, higher harmonics, usually not accounted for in analytical solutions, results in discrepancies between analytical and numerical results. The next geometry considered is of a plasma layer with only part of it having modulated permittivity. The presence of modulation of only part of the plasma layer is shown to create
transmission and reflection resonances. By tailoring parameters of the system, it is shown how the resonant frequencies can be shifted. The final geometry considers a copper grating beside a plasma and
transmission of a radio frequency wave. Even though the copper used here in this simulation is very absorbing, there are ranges of frequencies when
transmission or reflection are enhanced.

▼ Les virus foamy simiens (VFS) sont la troisième famille des rétrovirus complexes exogènes infectant l'Homme. Ces virus, zoonotique, sont transmis par des fluides biologiques (principalement la salive), lors d'un contact direct entre un individu et un singe infecté. Ils établissent une infection chronique chez l'hôte infecté. À ce jour, aucune pathologie n'a été associée à au cas d'infections humaines par le VFS, et aucun cas de transmission secondaire n'a été rapporté dans la population. L'infection VFS représente un modèle naturel de la restriction de l'émergence d'un rétrovirus simien chez l'Homme. Lors de ma thèse, j'ai caractérisé la réponse humorale contre les VFS chez des personnes vivant au Cameroun ou au Gal infectées suite à des morsures lors d'épisodes de chasse. J'ai montré la présence d'anticorps neutralisants les VFS dans 48 sujets infectés, à des titres élevés. La population étudiée est infectée par des virus de deux génotypes qui diffèrent dans le domaine central de la protéine impliqué dans la liaison au récepteur cellulaire. J'ai montré des réponses neutralisantes spécifiques de chaque génotype des sujets étudiés et des réactivités croisées chez 40% d'entre-eux. Parmi ces derniers, la moitié est infectée par deux souches virales. En conclusion, mon travail de thèse est la première caractérisation des anticorps neutralisants chez des personnes infectées chroniquement par un VFS zoonotique : ces anticorps sont fréquemment détectés, à des titres élevés et sont dirigés contre des épitopes conservés entre les VFS de chimpanzé et de gorille.
Simian foamy virus (SFV) are the third family of exogenous complex retroviruses infecting humans. These viruses, of origins, are transmitted by body fluids (mainly saliva), through a direct contact between an individual and an infected m establish a chronic infection in the infected human host. To date, neither pathology, nor secondary transmission has be to be associated with SFV infection in humans. Therefore, SFV represents a natural model of restriction emerging simiar in humans. During my PhD, I characterized the humoral response against SFV in people living in Cameroon and Gabon, mainly infected bites during hunting episodes. I showed the presence of SFV neutralizing antibodies in the plasma of 48 infected individ titers. Our study population is infected with viruses of 2 different genotypes, which differ in the central region of the En region involved in binding to the cellular receptor.While in 60% of cases, neutralizing response was specific to a single genotype, 40% of cases showed cross-reactivity. Cr( was associated in 50% of cases with co-infection with viruses from both genotypes.In conclusion, my PhD is the first study to characterize neutralizing antibodies in individuals chronically infected with a zoonotic SFV : these antibodies are frequently detected at high titers and are directed against epitopes commonly found in chimpanzee and gorilla SFV.

▼ This generative study, informed by grounded theory, examines the
transmission of values between grandmothers and adult-granddaughters, including how these values are transmitted bi-directionally and which values are age salient. Past research has been restricted to a unidirectional approach of
transmission of values from older generation to younger generation. The majority of past studies support that youth look to elders for guidance on life, values, and moral development. Few studies have ventured to consider a bi-directional process, where the elder also benefits from the relationship. Data gathering for this study began with a focus group to pilot the interview guide followed by semi-structured interviews with four grandmother-granddaughter dyads. Data indicate that grandmothers and adult-granddaughters experience a change in their relationship when the granddaughter reaches adulthood, that the relationship is mutually beneficial, that both generations learn from exchanges within the relationship, and that both grandmothers and granddaughters influence one another’s personal identity.

▼ My sound-based arts practice is currently concerned with the shift of focus from the materiality of the sonic art object to the conceptual and semantic dimensions involved in interaction within a system. The twentieth century saw the dawn of technologies that could not only mediate the sonic arts in new ways but also inform its techniques and tropes. Over the last few decades we have seen the emergence of the genres
Transmission and Telematic Art, the methodology of both often being informed by new concepts of space. The rise of post-industrial Capitalism situates us in a new epoch of spatial awareness. This seems particularly relevant now that mediated sonic and communication technologies are an integral part of our lives. Transmitting media “punching a hole in space” now ignore acoustic container boundaries: a sound heard and its source can exist separately yet simultaneously. Physical location and distance become less relevant. How does this create a shift in how we perceive the spatial within the practice of living?; and 2. redefining concepts of author and audience. All who participate are involved in authorship creating a form that is impossible to mediate to a passive audience 5. My work explores how this situation and the aesthetics deriving from it inform me as a practitioner within the medium of sound: the generative and emergent behaviour that arises from relationship as a form of “composition” and, of particular interest to me, the desire to shift focus from the traditional role of sound as an object of aesthetic expression to immersive interactive auditory space as a means of entering into dialogue with the multidimensional environment which humanity inhabits.

▼ The wireless communication technologies has been
found in all aspects of our social and economic life. However, the
research on the wireless power transmission (WPT) has not been well
established relatively. A strong driving force for the WPT
technologies comes from the consumer electronics and the
commercialization of electric vehicles (EV) recently. WPT provides
a simple, unified and safe means to recharge the battery. With an
extensive integration of this technique, the built-in battery size
can be minimized to reduce system volume and cost. After performing
a comprehensive review of the near-field WPT technologies, three
major issues including unstable magnetic coupling, inflexible
system architecture and susceptible power transmission are
identified as the obstacles in extending the WPT technique into the
dynamic application.
To provide a stable magnetic coupling for
power transmission, the optimal design of the magnetic coupler is
studied. The power transfer efficiency and power transfer
capability are first modelled by combination of circuit theory and
finite element analysis (FEA) to provide a basic for subsequent
design. A comparative study is then conducted to evaluate most of
the design considerations for magnetic couplers. An optimal design
method is finally introduced. A 30×30cm single layer compound
winding transmitter is proposed for charging the portable devices.
The uniform magnetic coupling is targeted such that the power
transmission is less sensitive to the relative position of the
receiver.
The system with multiple modular transmitter and
receiver are proposed to provide a more flexible system structure.
The interaction of the magnetic field between adjacent modular is
first studied. The flux cancellation phenomenon is identified and
found relative to the direction of the exciting currents. A
comprehensive comparison of the system configuration is then
conducted. The magnetic coupling and the power transfer capability
are evaluated for two system topologies and six different
configurations by FEA. Two most promising configurations are
selected with either the most stable magnetic coupling or the most
significant power transfer capability.
To avoid the power transfer
sensitivity to the magnetic coupling and load variations, a new
prototype and corresponding control method are proposed. The
load-independent operation modes for different compensation
topologies are derived by circuit analysis. Then, one of the
aforementioned modular transmitter topology is selected for stable
magnetic coupling, such that the load-independent characteristics
extends into the dynamic situations. As a result, the
load-independent and free-positioning features are satisfied
simultaneously. An experimental prototype has been built
tentatively for the wireless LED lighting system. A constant output
voltage is guaranteed on the receiver side when the receiver moves
along the transmitter array or when the load changes. Additionally,
due to the decoupled control between the primary side and the
secondary side the…

▼ This thesis presents the analysis and design
methods of directional and omnidirectional inductively coupled
wireless power transfer systems. Such system utilizes multiple
coils to generate high frequency alternating magnetic fields in
space and allows receivers to pick up power wirelessly in any
position. The objective of optimization is to achieve the maximum
power efficiency. Such kind of system allows the mobile devices to
be continuously charged without staying on a fixed place.
Self-
and mutual- inductance values of the coils are critical parameters
that affect the power efficiency of a wireless power transfer
system. An improved numerical calculation method is proposed and is
presented in this thesis. It combines the theory of partial
equivalent element circuit (PEEC) and empirical equations for
calculating certain types of straight conductors. The segmentation
method to discretize the conductor is optimized and verified. The
accuracy of the proposed method has been tested and compared to
both theoretical equations and measurements of practical coils, and
is proved to be accurate.
The time-varying magnetic fields
induced by the coils in a wireless power transfer system is the
\transporter" of the energy. A time-efficient visualization method
is proposed and is presented in this thesis. While commercial
finite element analysis (FEA) software such as ANSYS Maxwell can
perform transient analysis, the execution time is extremely long as
the accuracy greatly depends on the simulation time steps and the
number of iterations. The proposed method calculates the
time-instant currents in coils with the derived mathematic model
and then directly plots the time-varying magnetic fields. The
execution time is shortened to a few of minutes on a desktop
computer while the FEA solver takes a couple of hours on the same
model. Several types of multiple-coil systems are analyzed with
their magnetic field patterns.
To transmit power to arbitrary
directions, the magnetic field must be controlled with its
directions. According to the principle of superposition, a
three-orthogonal-coil transmitter structure is proposed. Several
current control methods are discussed to achieve omnidirectional
wireless power characteristics. One is a continuous scanning type
current scheme. The receivers placed in the designated area can
receive power with any locations and angles. Another one is a
discrete scanning type. It can be used to detect the load position
and therefore delivering power to the load with the maximum power
efficiency of the overall system. Simulations and experiments have
been carried out to verify the theory and they agreed well.
While the aforesaid omnidirectional system adopts the special
three-orthogonal-coil structure, the theory is generalized to
arbitrary numbers of transmitters. It is proved by mathematical
derivation that in a system with multiple transmitters and single
receiver, there exists an optimal efficiency point when currents in
the transmitter coils fulfill the certain relationships, regardless
of…

▼ Wireless power transfer technology has become a
preferable solution for supplying contactless energy over a certain
air-gap to various applications, ranging from microwatt biomedical
implantable devices to kilowatt battery charging systems for
electric vehicles, due to its exclusive features of safety,
flexibility and convenience. In such applications several sensors
mounted on both the input and output sides are typically necessary
to monitor the load variations or other system parameter changes.
The communication system of radio-frequency is installed to link
the two separate circuits between the power supplying and sinking
terminals as the feedback loop for the control purpose. The concept
of getting rid of such the complicated installations to monitor
systems parameters and loads only based on the input side
measurements is presented in this thesis.
An offline method to
identify the system parameters based on the input voltage and
current measurements as well as the use of a Genetic Algorithm is
proposed. It is effective in finding all the unknown parameters
even in large wireless power transfer systems which consist of
multiple resonant coils. This method has been successfully
illustrated in a three-coil experiment with good agreements between
calculated and measured parameter values.
If the system
parameters are known, a method is presented to show that, based
only on the measurements of the input voltage and current, the load
impedance of a wireless power transfer system can be
instantaneously monitored without using any direct measurement from
the load. Subsequently the power loss optimization and output power
control can be achieved by tuning the input frequency and adjusting
the input voltage amplitude. The principles are favorably verified
with practical measurements obtained from an eight-coil system.
In a series-series compensated two-coil system, both the mutual
inductance and load resistance can be determined uniquely with
measurement of the input voltage and current at only one specific
operating frequency. This discovery is useful in applications where
the load is movable. In addition it can be adopted as a simple
effective method to calculate the mutual inductance between any
pair of coupled coils if it is difficult to get access to either
coil.
There is a need for powering multiple loads simultaneously
from the power source in some applications. A computational method
for monitoring double loads from the front-end of a wireless power
transfer system without using any wireless communication link is
reported. Measurements of the system responses under more operating
frequencies are required to derive the load conditions with good
accuracy. A four-coil system has been set up to confirm the
effectiveness of the proposed approach under both static and
dynamic load conditions.

▼ Since the first reported case of AIDS 27
years ago, more than 70 million people have
been infected with HIV worldwide, and 25
million have died of AIDS. The Joint United
Nations Programme on HIV/AIDS (UNAIDS)
estimates that 33 million people are currently
living with HIV. The global prevalence
of HIV has leveled off, but the total number
of people living with HIV continues to grow.1
This article briefly discusses the roles
that different HIV transmission modes play
in the worldwide pandemic, and explains
how the global pandemic is actually a complex
mosaic of dynamic epidemics within
and between countries.2 Further, it discusses
matching appropriate prevention
responses to two different types of epidemics:
generalized and concentrated.

▼ Le monde rural est un secteur clé de notre économie. L'exploitation agricole n'est pas une entreprise comme les autres. La loi protège cette activité dont la transmission peut se révéler délicate. L'entreprise agricole française demeure bien souvent de type familial, même si les techniques les plus modernes y sont employées. Les problèmes humains y sont donc particulièrement importants, notamment dans le cadre de la transmission. Dans la pratique, de nombreuses questions doivent être résolues. Qui prendra la suite ? Un membre de la famille ? Un étranger ? Comment évaluer ? Que faut-il conserver ? Quels impôts devront être payés ? Combien de temps s'y prendre à l'avance ? Quelle personne consulter sur ces sujets très importants pour la survie de l'exploitation, la retraite de l'exploitant et la bonne gestion du patrimoine familial ? Les différents Conseils tels que le notaire sont des accompagnateurs dans cette opération, parfois longue et complexe. L’objectif de cette thèse est de traiter la transmission de l’entreprise agricole et les outils qui lui sont offerts à cette fin en examinant les intérêts d’une préparation en amont de la transmission avec la création d'une structure sociétaire par rapport à la transmission d'une entreprise individuelle (choix de la forme la plus adaptée, modalités de la mise en société et moyens d'adaptation aux objectifs particuliers) et d’observer qu'il peut également s'avérer intéressant d'organiser l'entreprise déjà exploitée sous forme de société, pour transformer sa forme juridique ou restructurer les activités et le patrimoine immobilier, ou adapter les statuts.Ces développements permettront de constater que l’entreprise agricole a un statut juridique en devenir. En effet, d’une façon générale, le Droit Français ne reconnaît pas l'entreprise agricole comme universum jus, sauf à cette entreprise à emprunter la forme d'une société impliquant la naissance d'une personne morale.Des étapes sont nécessaires à la reconnaissance juridique de l’entreprise agricole. Sur un plan juridique, et, jusqu'à 2006, la loi n'utilisait pas le terme d'"entreprise", mais celui d'"exploitation" (mot ambigu désignant à la fois l'activité agricole, et l'unité de production qui la réalise).Or s’il est ardu de définir l’Entreprise agricole, c’est justement cette absence de définition juridique qui rend difficile sa transmission.Le statut du fermage a été un obstacle préexistant à la loi d’orientation agricole du 5 janvier 2006, réforme pouvant paraître incomplète malgré les atouts de nouveaux outils juridiques tels que le fonds agricole (institution comparable au fonds de commerce tant du point de vue de la composition et des fonctions, que de la constitution , de la transmission et du nantissement) et le bail cessible, condition inéluctable du fonds agricole…des remèdes étant ainsi sujets à recherches…l’idéal étant d’aboutir, à terme, à une sorte de « Bien unique» à transmettre

▼ Influenza viruses are known to cause seasonal
epidemics that claim nearly half a million lives each year. In
addition, influenza viruses can also cause occasional pandemics
which, in the past, have resulted in a significant increase in the
number of influenza-related deaths worldwide. Pandemics arise when
influenza viruses with novel hemagglutinin (HA) and neuraminidase
(NA) surface proteins are introduced into the human population to
which there is no prior immunity. In addition to causing disease,
emerging viruses with pandemic potential must also be capable of
sustaining efficient human-to-human transmission. Transmission of
human influenza viruses occurs mainly through contact of the
mucosal membranes with respiratory droplets containing infectious
viral particles. Previous studies have shown that both
environmental and molecular factors can influence the efficiency of
influenza virus transmission such as air temperature and humidity,
and viral protein stability. Another factor which is likely to
affect the efficiency of influenza virus transmission is virion
morphology. Influenza virions are known to have multiple forms,
ranging from 100 nm spheres to filamentous particles with lengths
of up to 20 μm. Furthermore, there is a known correlation between
the size of respiratory droplets and the distance in which they can
travel. The smallest droplets measuring between 1 and 5 μm are
carried the greatest distances and are therefore thought to be
responsible for long range influenza virus transmission. For this
reason, influenza viruses that produce an abundance of small
spherical virions may exhibit higher transmission efficiencies than
viruses with large filamentous phenotypes.
In April of 2009, a
novel influenza virus (pH1N1) with an extremely high rate of
transmission efficiency emerged in the human population. This virus
was identified as an H1N1 reassortant between two influenza viruses
that had been circulating throughout pig populations for many
years. Most of the pH1N1 gene segments were originated from the
triple reassortant (TR) swine lineage, while the M and NA segments
are from viruses of the Eurasian swine lineage. Despite being
genetically similar, TR viruses rarely infected humans and were
incapable of sustaining efficient human-to-human transmission. We
therefore tested whether pH1N1 and TR viruses which differ in their
ability to transmit between humans also differ in virion
morphology. We discovered using immunofluorescence and electron
microscopy that the highly transmissible pH1N1 strain produced
predominantly spherical virions, whereas the poorly transmissible
TR isolates induced a filamentous phenotype. We also showed that
the difference in morphology between these viruses was due to
specific amino acid residues with the influenza matrix (M1) protein
at positions 30, 207, and 209. Substitution of these pH1N1 M1
residues with the corresponding TR residue by site-directed
mutagenesis resulted in recombinant pH1N1 viruses with filamentous
morphology, reduced viral growth kinetics, and small…

Understanding How Vaccination and Particular Virulence

▼ Epidemiologists focus on preventing and controlling
the spread of disease within populations; however the majority of
current experimental research only explores how virulence factors
interact with host immunity within or clinical therapeutics
targeted to individual hosts. The defining characteristic of any
infectious disease is its ability to transmit; investigation into
how host and bacterial factors contribute to facilitate
transmission is necessary and will contribute to novel strategies
that reduce infectious disease burden. This work utilizes a
recently developed model system to measure the transmission of
Bordetella bronchiseptica from infected mice to naïve susceptible
mice. In particular, this dissertation investigates how
vaccine-induced immunity and bacterial factors affect transmission
of the Bordetella. First, we examined the role of an
evolutionarily-conserved virulence factor utilized by many
bacterial pathogens, the Type III Secretion System (T3SS).
Investigation of a mutant lacking an active T3SS failed to transmit
to naïve susceptible mice. Following examination of multiple
parameters of transmission, initial colonization was identified to
be deficient. In the course of natural colonization, a host’s first
line of defense against a pathogen is its microbiota. Our analysis
revealed that during infection, the T3SS is required for B.
bronchiseptica to compete with microbiota in vivo and that
displacement of the host microbiota by wild-type B. bronchiseptica
occurs during transmission in our model system. Furthermore, prior
depletion of microbiota in susceptible mouse by enrofloxacin
restored the mutant’s ability to transmit. Another important
virulence factor utilized by the Bordetella is filamentous
hemagglutinin (FHA). A B. bronchiseptica mutant lacking fhaB was
also unable to transmit in this system. Mice inoculated with the
mutant failed to shed any bacteria during the time-course. As an
important factor in the transmission process, failure to shed
dramatically decreases the chances to pass disease to new hosts.
FHA is capable of modulating the immune system, and in its absence,
B. bronchiseptica failed to recruit neutrophils to the site of
infection, a key component previously linked to the shedding of B.
bronchiseptica. Finally, we have examined how current vaccine
strategies can affect transmission rates, identifying discrepancies
between whole-cell and acellular vaccines’ ability to control
transmission. Examination of mice previously vaccinated revealed
that only whole-cell vaccination was able to reduce shedding from
infected individuals. In particular, components of the immune
system that are recruited to the site of infection play an
important role in determining the amount of shedding. Increased
recruitment of B cells and decreased recruitment of neutrophils to
the nasal cavity of vaccinated mice correlated to the amount of
shedding observed from individual mice. Combined, the data here
suggest roles for both the T3SS and FHA in the transmission of
Bordetella, and that current vaccines,…

▼ To be able to keep up with energy demands new
transmission lines need to be designed and built. Design and planning is a long process due to the economic, political and environmental reasons. This project will analyze the line design with respect of the efficiency, percent of voltage regulation and power losses. In the second part of the project abnormal conditions will be analyzed for all of the shunt faults occurring on the different locations throughout the line. All data are selected base on the 500 kV line as reference. Conclusion is if we transmit low power over extra high voltage and long
transmission line the receiving-end voltage is greater than sending-end voltage, which is undesirable situation, and the faults are more severe if they occur closer to the source.

▼ Note:
Electricity is a crucial form of energy in our societies, and transmission lines are key elements to ensure the reliability of electric power grids. Continuity of service is the main preoccupation of electric utilities, and this continuity may be disrupted by a large variety of sources and accidents. Transmission lines, by their intrinsic topology, remain the grid components that are the most exposed to climatic sources of disruption. The most common and important source of dynamic loads on transmission lines results from wind effects on the towers and conductors. Conductors are particularly sensitive to wind effects as they are long and relatively flexible (compared to their supports) and are literally wind-catching structures in the power grid infrastructure. In cold climates, wind and ice have compounding effects on lines and give rise to the most severe design loading conditions. Therefore accurate prediction of the wind pressure on overhead conductors is essential to conduct a reliable assessment of the ine response, in terms of both electrical clearances and conductor loads transferred to supports. Spatial randomness of wind loads on overhead lines has already been addressed by stochastic analysis methods and is now taken into account in design with the use of so-called span factors. Further reasonable gains in wind load accuracy can be obtained by examining the physics of wind effects on conductors, in both non-iced and iced conditions, with improved predictions of lift and drag forces determined from fluid-structure interaction (FSI) analysis. The traditional design method to apply wind load on transmission lines is to convert the design wind speed to a static pressure through Bernoulli 's equation where the pressure is proportional to the air density and the squared wind speed. In this approach the fluid-structure interaction of wind and line components is ignored: wind is considered as a quasi-static load on conductors and supports, while special instability effects due to particular wind conditions suc as vortex shedding (Aeolian vibrations) and flutter (cable galloping) are accounted for separately with specific mitigation solutions if necessary. In gusty wind conditions with high turbulence intensity, conductors may experience large horizontal displacements that affect their surrounding wind flow. A physically accurate wind load evaluation on conductors is possible by computational wind-structure interaction analysis. To date, largely due to its high computational cost and the lack of experimental data to validate computational models, an advanced fluid-structure analysis framework for wind-cable interaction has not been developed. In this study a new approach based on FSI analysis to evaluate equivalent wind loads on conductors is developed. The first step in such an approach is accurate evaluation of wind pressure on conductor. For this purpose the FSI analysis is carried in two dimensions where the detailed bare and iced conductor section geometry and surrounding air flow are modeled,…

▼ Digital video transmission is widely used nowadays in multimedia. Frame dropping, freeze and reduced number of frames in the transmitted video are common symptoms of bad transmission quality. In order to assess the quality of transmission, a criterion is introduced in a model for a no reference video jerkiness measure [3]. This model is dierent from the former models presented as it depends on viewing conditions and video resolutions, so it is applicable for any frame size from QCIF to HD. The model uses simple mathematical equations of jerkiness and can be used for any video sequence [3]. A model of reduced reference method (Qtransmission) which depends on a pre-measured Jerkiness is introduced as a suggestion of future work.

▼ D.Ing.
Alternating current systems employing single-frequency sinusoidal waveforms render optimal service when the currents in that system are also sinusoidal and have a fixed phase relationship to the voltages that drive them. Under unity- power factor conditions, the currents are in phase with the voltages and optimal net-energy transfer takes place under minimum loading conditions, i.e. with the lowest effective values of current and voltage in the system. The above conditions were realised in the earlier years, because supply authorities generated 50 Hz sinusoidal voltages and consumers drew 50 Hz sinusoidal currents with fixed phase relationships to these voltages. Static and rotating electrical equipment like transformers, motors, heating and lighting equipment were equally compatible with this requirement and well-behaved AC networks were more the rule than the exception. The fact that three-phase systems conveyed the bulk of the power from one topographical location to the next did not constrain the utilisation of that concept at all, even though poly-phase transmission systems were necessary to increase the economy of transmission and to furnish non-pulsating power transfer. Also, additional theory had to be developed to handle unbalanced conditions in these multi-phase systems and to take care of complex network analysis and fault conditions. Difficulties begin to manifest themselves when equipment not meeting these requirements is connected to the network and when the currents it draws are not sinusoidal. An increasing number of applications demand DC-voltage supplies from which DC-currents are to be drawn. Because power transmission is carried out by means of AC networks, the DC is furnished by converting or rectifying the AC-supply. Power-electronic circuits, of which the R 2P2 power supplies the AEC employs are no exception, employ line-commutated AC/DC converters in their front-ends, and fall into that category. Although these line-commutated, phase-controlled AC/DC converters are capable of handling giga-watt power levels, line-frequency commutation causes the currents they draw on the AC-side to be distorted, even though still to be periodic. These non-sinusoidal currents, drawn from the source, along the transmission lines and through other distribution system immittances, also give rise to non-sinusoidal voltage drops between the source and the load, which results in distorted voltage waveforms at other nodes and at the load. Harmonic penetration studies are essential to evaluate the performance of transmission systems in the presence of current distortion sources. These sources do not only bring about voltage distortion within the confines of their own borders, but extend their influence outside into those of other consumers as well. Supplyutilities are wary of the distortion introduced into their networks by consumers and initial recommendations have now given way to rigid standards for curbing harmonic pollution by consumers Because conventional steady-state alternating current circuit theory…

▼ Le confort des passagers à l'intérieur des avions pendant le vol est un axe en voie d'amélioration constante. L'augmentation de la proportion des matériaux composites dans la fabrication des structures aéronautiques amène de nouvelles problématiques à résoudre.Le faible amortissement de ces structures, en contre partie de leur poids/raideur faible, est non favorable sur le plan acoustique, ce qui oblige les concepteurs à devoir trouver des moyens d'amélioration. De plus, les mécanismes de
transmission du son au travers d'un système double paroi de type aéronautique ne sont pas complètement compris, c'est la raison qui motive cette étude. L'objectif principal de ce projet est de constituer une base de données pour le partenaire industriel de ce projet : Bombardier Aéronautique. En effet, les données expérimentales de performance d'isolation acoustique, de systèmes complets représentatifs d'un fuselage d'avion sont très rares dans la littérature scientifique. C'est pourquoi une méthodologie expérimentale est utilisée dans ce projet. Deux conceptions différentes de fuselage sont comparées. La première possède une peau (partie extérieure du fuselage) métallique raidie, alors que la deuxième est constituée d'un panneau sandwich composite. Dans les deux cas, un panneau de finition de fabrication sandwich est utilisé. Un traitement acoustique en laine de verre est placé à l'intérieur de chacun des fuselages. Des isolateurs vibratoires sont utilisés pour connecter les deux panneaux du fuselage. La simulation en laboratoire de la couche limite turbulente, qui est la source d'excitation prépondérante pendant la phase de vol, n'est pas encore possible hormis en soufflerie. C'est pourquoi deux cas d'excitation sont considérés pour essayer d'approcher cette sollicitation : une excitation mécanique (pot vibrant) et une acoustique (champ diffus). La validation et l'analyse des résultats sont effectuées par le biais des logiciels NOVA et VAONE, utilisés par le partenaire industriel de ce projet. Un des objectifs secondaires est de valider le modèle double paroi implémenté dans NOVA. L'investigation de l'effet de compression local du traitement acoustique, sur la perte par
transmission d'une simple paroi, montre que cette action n'a aucun effet bénéfique notable. D'autre part, il apparaît que la raideur des isolateurs vibratoires a un lien direct avec les performances d'isolation du système double paroi.Le système double paroi avec peau composite semble moins sensible à ce paramètre.Le modèle double paroi de NOVA donne de bons résultats concernant le système double paroi avec une peau métallique. Des écarts plus importants sont observés en moyennes et hautes fréquences dans le cas du système avec une peau composite. Cependant, la bonne tendance de la prédiction au vu de la complexité de la structure est plutôt prometteuse.

▼ Transmission charges are levied against generators and suppliers for their use of transmission networks. The majority of existing transmission charging methods were designed for a system dominated by conventional and controllable generation. The resultant transmission charges reflect network users’ contribution to the system peak. The integration of renewable generation brings fundamental challenges in transmission planning and charging. Main criteria of transmission planning have changed from meeting system peak demand to the trade-offs between operational and investment costs. Transmission charging is required to effectively reflect these trade-offs. This research work aims to develop novel transmission charging methods for low carbon power systems, reflecting the contribution to transmission investments from different generation technologies, different locations, and critically different times. It firstly identifies the key drivers and key conditions of transmission investments under the economic criteria. In the second step, the key drivers and conditions are reflected in the developing of T-LRIC method, ToU-LRIC method and ToU-ICRP method. Major innovations of the proposed methods include 1. reflecting the trade-offs between operational and investments costs by employing investment time horizons to reflect the impacts of system operation on transmission investments (T-LRIC method and ToU-LRIC method). 2. differentiating various generation technologies by firstly quantifying their impacts on the time horizons of network investments, then translating these impacts to transmission charges (T-LRIC method and ToU-LRIC method). 3. providing time-specific transmission charges, in which Time-of-Use periods are identified by clustering time-series congestion costs or transmission charges, thus reflecting the typical conditions of system congestions and the required transmission investments (ToU-LRIC method and ToU-ICRP method). The main benefits from introducing these innovations are i) to guide the short-run behaviours of network users, thus mitigating transmission congestions and promoting efficient utilization of existing networks; ii) to incentivize appropriate generation expansion, thus reducing or deferring costly future transmission investments.
