▼ The purpose of this thesis is to examine the feasibility of using a microturbine to power an off-road Series Hybrid Autonomous Vehicle (SHEV), and evaluate the benefits and drawbacks inherent in using a microturbine rather than an Internal Combustion Engine (ICE). The specific power plant requirements for a low speed hybrid vehicle that must operate extensively as an Electric Vehicle (EV) and run on JP-8 (a diesel equivalent) are unusual; few options can adequately address all of these needs. Most development of Hybrid Electric Vehicles (HEVs) has focused on gasoline ICE power plants, but Diesel ICEs are heavier, which has an adverse effect on EV range.
While mechanically-linked turbine vehicles failed to have the same performance abilities of their ICE counterparts, a microturbine generator-powered SHEV can take advantage of its battery pack to avoid the issues inherent in its mechanical predecessors. A microturbine generator is mechanically decoupled from the powertrain, allowing for an incredibly power dense power plant that lightens the weight of the vehicle. This weight reduction directly correlates to an increased EV operational range, enhancing mobility, stealth, and the tactical effectiveness of the squad that the vehicle is intended to support.
To determine the full impact that a microturbine might have on this specific SHEV, modeling of the vehicle was conducted to directly compare a microturbine and an ICE power plant using two drive cycles that were designed to simulate the typical operation specific to the vehicle. Drive cycle analysis revealed that the improved EV performance and design flexibility offered by the microturbine's weight justifies the selection of a microturbine over an ICE for this specific case. This decision is dependent upon several factors: a microturbine with fuel efficiency comparable to an ICE, the selection of a large battery pack, and an emphasis on EV operations.

▼ Hardware-in-the-loop (HIL) simulations allow for rapid
testing and validation of prototype components and their
mathematical models. Development time of these complex components
and their control systems, such as high voltage batteries, advanced
internal combustion engines and electric motors seen in hybrid
electric vehicles, is also decreased. Teaching these skills for
more than one specific component or system of components is
difficult given the effort to pull together complicated
experimental hardware and or software. This presents a need to
develop a tool that adapts quickly to a desired test configuration
and performs multiple test modes for an assortment of prototype
components. This thesis discusses the development of such a tool
and explores its ability to test and operate in multiple
configurations. This thesis details the design and testing of an
HIL test bench that performs high voltage battery, internal
combustion engine, electric-motor and controller HIL simulations.
The same test bench is designed to be tested in a small vehicle as
an all electric, series hybrid, parallel hybrid, and conventional
powertrain.

▼ Low Temperature Combustion (LTC) holds promise for high thermal efficiency and low Nitrogen Oxides (NOx) and Particulate Matter (PM) exhaust emissions. Fast and robust control of different engine variables is a major challenge for real-time model-based control of LTC. This thesis concentrates on control of powertrain systems that are integrated with a specific type of LTC engines called Homogenous Charge Compression Ignition (HCCI). In this thesis, accurate mean value and dynamic cycleto- cycle Control Oriented Models (COMs) are developed to capture the dynamics of HCCI engine operation. The COMs are experimentally validated for a wide range of HCCI steady-state and transient operating conditions. The developed COMs can predict engine variables including combustion phasing, engine load and exhaust gas temperature with low computational requirements for multi-input multi-output realtime HCCI controller design. Different types of model-based controllers are then developed and implemented on a detailed experimentally validated physical HCCI engine model. Control of engine output and tailpipe emissions are conducted using two methodologies: i) an optimal algorithm based on a novel engine performance index to minimize engine-out emissions and exhaust aftertreatment efficiency, and ii) grey-box modeling technique in combination with optimization methods to minimize engine emissions. In addition, grey-box models are experimentally validated and their prediction accuracy is compared with that from black-box only or clear-box only models. A detailed powertrain model is developed for a parallel Hybrid Electric Vehicle (
HEV) integrated with an HCCI engine. The
HEV model includes sub-models for different
HEV components including Electric-machine (E-machine), battery, transmission system, and Longitudinal Vehicle Dynamics (LVD). The HCCI map model is obtained based on extensive experimental engine dynamometer testing. The LTC-
HEV model is used to investigate the potential fuel consumption benefits archived by combining two technologies including LTC and electrification. An optimal control strategy including Model Predictive Control (MPC) is used for energy management control in the studied parallel LTC-
HEV. The developed
HEV model is then modified by replacing a detailed dynamic engine model and a dynamic clutch model to investigate effects of powertrain dynamics on the
HEV energy consumption. The dynamics include engine fuel flow dynamics, engine air flow dynamics, engine rotational dynamics, and clutch dynamics. An enhanced MPC strategy for
HEV torque split control is developed by incorporating the effects of the studied engine dynamics to save more energy compared to the commonly used map-based control strategies where the effects of powertrain dynamics are ignored.
LTC is promising for reduction in fuel consumption and emission production however sophisticated multi variable engine controllers are required to realize application of LTC engines. This thesis centers on development of model-based controllers for…

▼ Li-ion battery is now replacing nickel-metal hydride
(NiMH) for hybrid electric vehicles (HEV). The advantages of Li-ion
battery over NiMH are that it can provide longer life, higher cell
voltage and higher energy density, etc. However, there are still
some issues unsolved for Li-ion battery to fully satisfy the HEV
requirement. At high temperature, thermal runaway may cause safety
issues. At low temperature, however, its performance is
dramatically reduced and also Li deposition may occur. Furthermore,
degradation due to side reactions in the electrodes during cycling
and storage results in capacity loss and impedance rise. An
electrochemical-thermal coupled model is first used to predict
performance of individual electrodes of Li-ion cells under HEV
conditions that encompass a wide range of ambient temperatures. The
model is validated against experimental data of not only the full
cell but also individual electrodes and then used to study lithium
deposition on the negative electrode during charging Li-ion battery
at subzero temperature. The simulated property evolution, e.g. Li
concentrations in electrode and electrolyte, shows that either low
temperature or high charge rate may force Li insertion (into the
negative carbon electrode) to occur in a narrow region near the
separator. Therefore, Li deposition is mostly like to happen in
this location. Modeling simulation shows that reduction of the
negative electrode particle size can reduce Li deposition, which
has same effect as improvement of the Li diffusion coefficient in
the negative electrode. The model is also used to study charge
protocols at subzero temperature. Model simulation shows that
employing pulse current can improve cell temperature by the heat
generated inside the cell, thus this designed charge protocol is
able to reduce Li deposition and improve the charge efficiency as
well. Individual aging mechanism is then implemented into each
electrode to study Li-ion battery degradation during accelerated
aging tests. The experimentally observed aging phenomena are
interpreted using the degradation model. The simulated results show
that the positive electrode active material loss is the main cause
of capacity loss and impedance growth. And this is the key step for
a model to well catch the experimentally observed aging phenomena
in the two electrodes. In the future work, the degradation model
will further help to prolong battery life through engineering and
optimization in HEV applications.

▼ Hepatitis E virus (
HEV) is a major cause of enterically transmitted acute viral hepatitis in developing countries that lack proper hygienic infrastructure. Hepatitis E is globally distributed and has emerged as an important public health disease in both developing and industrialized countries.
HEV is a non-enveloped virus carrying a single-stranded positive-sense RNA genome of approximately 7.200 bp in length. The life cycle of
HEV is poorly understood due to the lack of an efficient cell culture system. Animal model systems, including non-human primates, swine, and chickens are being used to study some fundamental aspects of the
HEV biology. Recently, novel animal strains of rat and rabbit
HEV have been discovered, and whose usage as animal model systems needs to be established.
HEV infections in pigs and chickens provide excellent model systems to study the replication and pathogenesis aspects of
HEV. Recently, we identified a hypervariable region (HVR) in the open reading frame 1 (ORF1) of
HEV. The objectives of this dissertation were to utilize chicken and swine model systems to study the role of HVR in
HEV infection in vivo, to determine the effects of HVR on replication of
HEV in vitro, and to analyze the effect of exchange of HVR among different genotypes on the replication-competency and virion production in vitro.
Extensive sequence variability in the HVR among
HEV strains of different genotypes prompted us to study the dispensability of this region. Initially we constructed two partial deletion mutants of genotype 1 human
HEV, hHVRd1 and hHVRd2, with in-frame deletion of amino acids (aa) 711 to 777 and 747 to 761 in the HVR of a sub-genomic GFP
HEV replicon. Expression of enhanced green fluorescent protein by the mutant hHVRd2 confirmed the dispensability of amino acid residues 747-761 of the HVR. To confirm our in vitro results, specific-pathogen-free (SPF) chickens were intra-hepatically inoculated with capped RNA transcripts from three avian
HEV HVR-deletion mutants: mutants aHVRd1 (Δ557-585), aHVRd2 (Δ612-641), and aHVRd3 (Δ557-641). Chickens intra-hepatically inoculated with the mutants, aHVRd1 and aHVRd2, developed active viral infection as evidenced by seroconversion, viremia, and fecal virus shedding. Mutant aHVRd3, with a larger HVR deletion, was apparently attenuated in chickens. Additionally, we used the swine model system to further verify our results from the chicken study. The infectivity of four genotype 3 swine
HEV HVR-deletion mutants, sHVRd1 (Δ712-790), sHVRd2 (Δ722-781), sHVRd3 (Δ735-765), and sHVRd4 (Δ712-765) constructed using the genotype 3 swine
HEV as the backbone was determined in SPF pigs. Pigs intra-hepatically inoculated with capped RNA transcripts from the mutants sHVRd2, sHVRd3, and sHVRd4 developed active viral infection, whereas mutant sHVRd1 (Δ712-790), with a nearly complete HVR deletion, exhibited an attenuation phenotype. The data from these studies indicate that deletions in HVR do not abolish
HEV infectivity in vitro or in vivo, although evidence for attenuation was…

▼ Hepatitis E virus (
HEV) is the main cause of acute viral hepatitis worldwide, predominantly in developing areas where it is endemic. Recently,
HEV has gained more attention in the developed world, prompting several industrialized countries to assess seroprevalence rates using blood donor samples. The seroprevalence among Canadian blood donor samples collected from July 2013 - December 2015 was 5.84% (240/4,107). None of the 14,053 samples tested were positive for
HEV RNA. There was no significant increase in the high-risk groups we tested. HIV was determined to be a significant risk-factor for
HEV infection in a retrospective study of Kenya-based sex-worker cohorts, but not so in a Canadian cohort of HIV-positive intravenous drug users. Overall,
HEV seroprevalence in Canada is lower than that published in other countries. This together with failing to detect
HEV RNA in Canadian blood donations indicates that
HEV currently poses low risk to the Canadian blood supply.

▼ Today uncertainties of petroleum supply and concerns over global warming call for further advancement of green vehicles with higher energy efficiency and lower green house gas (GHG) emissions. Development of advanced hybrid electric powertrain technology plays an important role in the green vehicle transformation with continuously improved energy efficiency and diversified energy sources. The added complexity of the multi-discipline based, advanced hybrid powertrain systems make traditional powertrain design method obsolete, inefficient, and ineffective. This research follows the industrial leading model-based design approach for hybrid electric vehicle powertrain development and introduces the optimization based methods to address several key design challenges in hybrid electric powertrain and its control system design. Several advanced optimization methods are applied to identify the proper hybrid powertrain architecture and design its control strategies for better energy efficiency. The newly introduced optimization based methods can considerably alleviate the design challenges, avoid unnecessary design iterations, and improve the quality and efficiency of the powertrain design. The proposed method is tested through the design and development of a prototype extended range electric vehicle (EREV), UVic EcoCAR. Developments of this advanced hybrid vehicle provide a valuable platform for verifying the new design method and obtaining feedbacks to guide the fundamental research on new hybrid powertrain design methodology.

▼ HEV infection is an emerging public health problem worldwide Data concerning HEV infection in HIV+ patients in Greece is scare. The aim of the study was to determine HEV seroprevalence in patients with HIV infection in Greece. We studied 243 HIV(+) patients 214 men (88%) and 29 women (12%) with a median age of 45 years (range 19–83) who attended the HIV unit of Pathophysiology Department of Laikon General Hospital in Athens for the presence of anti-HEV IgG antibodies with (EIA) (EIA HEV IgG, Adaltis, Rome, Italy). Eighteen/243 patients (7.3%) were positive for HEV IgG antibodies, a seroprevalence that was not different from that described for the blood donors group from Greece. There was no difference of the presence of HbsAg, hepatitis C and hepatitis A between the HEV(+) and HEV(-) patients. There was no statistically significant difference between the HEV(+) and HEV(-) group in terms of HIV acquisition, sexual orientation, median duration of HIV infection, ART treatment, or duration of ART. Only the median age of HEV(+) was 52 years (35–78) while that of HEV(-) was 44 years (19–83)(P=0.03). Only 2/18(11.1%) HEV(+) HIV(+) patients had abnormal ALT and AST values. The seroprevalence of hepatitis E in HIV(+) patients in Greece seems to be the same with that of the general population thus implying that HIV infection is not a risk factor for HEV infection and only age shows a positive correlation with seropositivity.

Μελετήσαμε 243 HIV(+) ασθενείς από τους οποίους 214 ήταν άντρες (88%) και 29 γυναίκες (12%) με μέσο όρο ηλικίας 45 έτη (εύρος 19-83), οι οποίοι παρακολουθούνται στην Μονάδα Ειδικών Λοιμώξεων της Παθολογικής Φυσιολογίας του Γενικού Νοσοκομείου Αθηνών «Λαϊκό», για την εμφάνιση αντισωμάτων IgG έναντι του ιού της ηπατίτιδας Ε με ΕΙΑ. 18 στους 243 ασθενείς (7.3%) βρέθηκαν θετικοί στον ιό της ηπατίτιδας Ε, επιπολασμός που δεν διέφερε από αυτόν που περιγράφεται στους δότες αίματος στην Ελλάδα. Καμμιά διαφορά δεν υπήρξε, όσον αφορά την παρουσία HbsAg, ηπατίτιδας C και ηπατίτιδας Α, μεταξύ των HEV(+) και HEV(-) ασθενών. Δεν παρουσιάσθηκε στατιστικά σημαντική διαφορά ανάμεσα στους HEV(+) και HEV(-) από την άποψη της μετάδοσης του HIV, του αφροδισιακού τρόπου μετάδοσης, της χρονικής διάρκειας της HIV λοίμωξης, της έναρξης της αντιρετροϊκής θεραπείας, ή χρονική διάρκεια λήψης της αντιρετροϊκής θεραπείας. Η μέση ηλικία των HEV(+) ήταν 52 έτη (εύρος 35-78), ενώ των HEV(-) 44 έτη (εύρος 19-83) (P=0,03). Μόνο 2 από τους 18 ασθενείς (11,1%) με συλλοίμωξη HIV/HEV είχαν μη φυσιολογικές τιμές ALT και AST. Ο επιπολασμός της ηπατίτιδας Ε σε HIV(+) στην Ελλάδα φαίνεται να είναι ίδιος με αυτόν του γενικού πληθυσμού, υπονοώντας κατά συνέπεια ότι η HIV λοίμωξη δεν αποτελεί παράγοντα κινδύνου για μόλυνση…

▼ Alphavirus et virus de l'hépatite E, appartiennent à l'alpha-like supergroupe de virus à ARN simple brin positif. Dans cette thèse, la caractérisation fonctionnelle de l'ARNm plafonnement enzyme et le domaine macro sont abordées, afin d'élucider leur rôle dans la réplication virale et de les évaluer en tant que cibles antivirales possibles.Les alphavirus possèdent un mécanisme unique de coiffe de l'ARNm viral impliquant la protéine non structurale nsP1. Nous présentons ici la caractérisation biochimique de nsP1d'alphavirus et son potentiel comme cible antivirale. Pour cela, différents tests enzymatiques ont été développés afin de mieux comprendre et de découpler les différentes étapes de la réaction catalysée par nsP1. Nous avons pu montrer pour la première fois chez les alphaviurs le guanylyltransfert de m7GMP sur l'extrémité 5'-diphosphate d'un ARN. Les techniques développées mises au point ont été mises à profit pour élucider le mode d'action d'une nouvelle classe d'antiviraux d'alphavirus.Le Macro domaine est un domaine protéique ancien et conservé et largement distribué dans tout le règne vivant. Nous déclarons que le domaine Macro de virus de l'hépatite E sert une protéine hydrolase ADP-ribose pour inverser la protéine ADP-ribosylation. L'abolition de l'activité diminue considérablement la réplication d'un réplicon sub-génomique du VHE. L'activité est également présente dans les macro domaines du SRAS-CoV et VEEV. Nos résultats montrent que les macro domaines viraux servent ADP-ribose protéine hydrolase et jouent un rôle important dans la réplication virale, peut-être grâce à la modulation de la réponse antivirale de l'hôte.
Alphavirus and Hepatitis E virus, belong to alpha-like supergroup of positive single stranded RNA viruses. In this thesis, the functional characterization of mRNA capping enzyme and Macro domain are addressed, in order to elucidate their role in the viral replication and to evaluate them as possible antiviral targets. Part I: Alphaviruses are known to possess a unique viral mRNA capping mechanism involving the viral non-structural protein nsP1. Here we report the biochemical characterization and antiviral investigation of alphavirus nsP1. Different enzymatic assays were developed to further understand and uncouple the different reaction steps catalyzed by nsP1. The final guanylyltransfer of m7GMP onto a 5'-diphosphate RNA oligonucleotide was observed for the first time in vitro with an alphavirus nsP1. Taking advantage of the developed techniques, the mode of action of a novel class of alphavirus antivirals, [1,2,3]triazolo[4,5-d]pyrimidin-7(6H)-ones, was deciphered. Part II: Macro domain is an ancient and highly evolutionarily conserved protein domain widely distributed throughout all kingdoms of life. Here, we report that the Macro domain from hepatitis E virus serves as an ADP-ribose protein hydrolase to reverse protein ADP-ribosylation. Abbrogation of this activity dramatically decreases replication of a HEV sub-genomic replicon. This activity is also present in Macro domains from…

▼ Hepatitis E Virus infection is an emerging cause of acute viral hepatitis and gastro-enteritis around the world. It is believed that every year about 10,000 people die because of the consequences of an infection with this virus. As early as 1983, a researcher voluntarily infected himself with
HEV to study the pathogenesis (Balayan et al., 1983). Despite this effort, nowadays still only limited knowledge of
HEV is present. Recently, a cell culture infection system has become available which can lead to a breakthrough in our knowledge on this virus. Here we present an overview of the present understanding of
HEV in which we focus on the molecular mechanisms of this threat, the technical possibilities of and the challenges in diagnosis of
present or recent
HEV infection.

▼ Georgia Tech has the privilege of competing in EcoCAR 3, a four-year competition in which 16 universities are given a stock 2016 Chevrolet Camaro and work to transform it into a hybrid electric sports car. In this thesis, an overview of the first two years of the author’s work on the team as the Engineering Manager, the graduate student overseeing all vehicle engineering work, will be detailed. The competition will be introduced and described before a discussion on vehicle electrification and the various ways it has been achieved by manufacturers and competition teams. Next, the design of the Georgia Tech vehicle will be presented with a focus on powertrain and supporting component selection. The vehicle model underlying many of these decisions will then be discussed in detail, showing how the team used Simulink and Engineering Equation Solver to effectively predict vehicle performance, emissions, energy consumption, and cooling needs. Building on this, the controls design process known as model/software/hardware in the loop will be discussed in the context of the Georgia Tech team’s use of this process. Finally, a progress update will be given, including photos of the team vehicle in current build state weeks before the Year 2 Competition.

▼ In this thesis, the primary powertrain components of a power split hybrid electric vehicle are modeled. In particular, the dynamic model of the energy storage element (i.e., traction battery) is exactly linearized through an input transformation method to take advantage of the proposed optimal control algorithm. A lipschitz continuous and nondecreasing cost function is formulated in order to minimize the net amount of consumed fuel. The globally optimal solution is obtained using a dynamic programming routine that produces the optimal input based on the current state of charge and the future power demand. It is shown that the global optimal control solution can be expressed in closed form for a time invariant and convex incremental cost function utilizing the interval back propagation approach. The global optimality of both time varying and invariant solutions are rigorously proved. The optimal closed form solution is further shown to be applicable to the time varying case provided that the time variations of the incremental cost function are sufficiently small. The real time implementation of this algorithm in Simulink is discussed and a 32.84 % improvement in fuel economy is observed compared to existing rule based methods.

▼ Hepatitis E virus (HEV) is an emerging enteric pathogen responsible for most acute hepatitis worldwide. This dissertation presents data from studies conducted from 2001-2006 in the Matlab Health Research Center population under the International Center for Diarrheal Disease Research, Bangladesh. These studies define the previously unknown burden of HEV in rural Bangladesh and address gaps in HEV epidemiology. This work begins with a literature review, focusing on the challenges presented by this virus: the unexplained high case fatality in pregnancy, the absence of HEV in children, the rapid deterioration of immunity, and recent evidence implicating some HEV genotypes as zoonoses. The first study is a cross-sectional assessment of antibody seroprevalence to three hepatitis viruses (B,C&E) in a representative random population sample (n=1134). This study revealed a 22.5% seroprevalence of anti-HEV, 35.2% anti- HBc and 1.5% anti-HCV. Anti-HEV seroprevalence peaked in
the second/third decades of life, as seen in India/Nepal. Male gender and outdoor employment were significantly associated with seropositivity. The second study follows this baseline cohort longitudinally for 18 months to determine HEV infection and disease rates. From 837 person-years (P-Y) of exposure, an incidence rate of 60.3/1000P-Y was estimated. Agespecific seroincidence increased in subsequent 10-year categories, peaking at 41-50y. Although clinical illness seemed infrequent, a disease:infection ratio as high as 49 per 100 (95%CI:31–73) was estimated. Third, an exploratory nested case control study attempts to identify putative risk factors for sporadic hepatitis E disease. Over 22 months, 13 field workers used a morbidity-scoring algorithm to identify acute hepatitis-like illness in their catchment population of 23,500. Finally, 46 confirmed HEV infections were iii compared to 134 sero-naïve age-matched controls. Cases were less likely to be <15y, female or use unsanitary
latrines in their homes. Outdoor employment, work outside the home, and travel to a town/city emerged as risk factors. Unlike in previous studies, recent contact with a “jaundice” patient and injection exposures were significant. These studies establish that: HEV is endemic in rural Bangladesh; sporadic infections are frequent in the absence of outbreaks; and, aside from classic hygiene risk factors, there may be other pathways through which HEV is transmitted.

▼ The development of embedded control systems for a Hybrid Electric Vehicle (
HEV) is a challenging task due to the multidisciplinary nature of
HEV powertrain and its complex structures. Hardware-In-the-Loop (HIL) simulation provides an open and convenient environment for the modeling, prototyping, testing and analyzing
HEV control systems. This thesis focuses on the development of such a HIL system for the hybrid electric vehicle study. The hardware architecture of the HIL system, including dSPACE eDrive HIL simulator, MicroAutoBox II and MotoTron Engine Control Module (ECM), is introduced. Software used in the system includes dSPACE Real-Time Interface (RTI) blockset, Automotive Simulation Models (ASM), Matlab/Simulink/Stateflow, Real-time Workshop, ControlDesk Next Generation, ModelDesk and MotoHawk/MotoTune. A case study of the development of control systems for a single shaft parallel hybrid electric vehicle is presented to summarize the functionality of this HIL system.

▼ The powertrain design and control strategies for three representative hybrid and plug-in hybrid electric vehicles (
HEV/PHEVs), a plug-in hybrid passenger car, a plug-in hybrid race car, and a hybrid electric mining truck, have been investigated through the system modeling, simulation and design optimization. First, the pre-transmission gen-set couple Plug-in Series-Parallel Multi-Regime (SPMR) powertrain architecture was selected for PHEV passenger car. Rule-based load following control schemes based on engine optimal control strategy and Equivalent Consumption Minimization Strategy (ECMS) were used for the operation control of the passenger car PHEV powertrain. Secondly, the rear wheel drive (RWD) post-transmission parallel through road powertrain architecture was selected for race car PHEV. A high level supervisory control system and ECMS control strategy have been developed and implemented through the race car’s on-board embedded controller using dSPACE MicroAutobox II. In addition, longitudinal adaptive traction control has been added to the vehicle controller for improved drivability and acceleration performance. At last, the feasibility and benefits of powertrain hybridization for heavy-duty mining truck have been investigated, and three hybrid powertrain architectures, series, parallel and diesel-electric, with weight adjusting propulsion system have been modeled and studied. The research explored the common and distinct characteristics of hybrid electric propulsion system technology for different vehicular applications, and formed the foundation for further research and development.

▼ HEV is an important public health concern due largely to water-borne outbreak. Recent research confirms individual cases of zoonotic transmission due to human exposure to contaminated animal meats. At least four recognized and two putative genotypes of mammalian
HEV have been reported: genotypes 1 and 2 are restricted to humans whereas genotypes 3 and 4 are zoonotic. In addition to humans, strains of
HEV have been genetically identified from pigs, chickens, rats, mongoose, deer, rabbits and fish. The current experimental vaccines are all based on a single strain of
HEV, even though multiple genotypes of
HEV are co-circulating in some countries and thus an individual may be exposed to more than one genotype. Therefore, it is important to know if prior infection with a genotype 3 swine
HEV will confer protective immunity against subsequent exposure to genotypes 3 and 4 human and swine
HEV. In the first study, specific-pathogen-free pigs were divided into 4 groups of 6 each. Pigs in the three treatment groups were each inoculated with a genotype 3 swine
HEV, and 12 weeks later, challenged with the same genotype 3 swine
HEV, a genotype 3 human
HEV, and a genotype 4 human
HEV, respectively. Sera from all pigs were tested for
HEV RNA and IgG anti-
HEV, and fecal samples were also tested for
HEV RNA each week. The pigs inoculated with swine
HEV became infected as evidenced by fecal virus shedding and viremia, and the majority of pigs also developed IgG anti-
HEV prior to challenge at 12 weeks post-inoculation. After challenge, viremia and fecal virus shedding of challenge viruses were not detected, suggesting that prior infection with a genotype 3 swine
HEV prevented pigs from developing viremia and fecal virus shedding after challenge with homologous and heterologous genotypes 3 and 4
HEV, respectively.
Immunogenic epitopes are located within the open reading frame 2 (ORF 2) capsid protein and recombinant ORF 2 antigens are capable of preventing
HEV infection in non-human primates and chickens. In the second study we expressed and purified N-truncated ORF 2 antigens based on swine, rat, and avian
HEV strains. Thirty pigs were randomly divided into groups of 6 pigs each and initially vaccinated with 200µg swine ORF 2 antigen, rat ORF 2 antigen, avian ORF 2 antigen, or PBS buffer (positive and negative control groups) and booster with the same vaccine 2 weeks later. At 4 wks, after confirming seroconversion to IgG anti-
HEV antibody with ELISA, all groups except the negative control were challenged with swine genotype 3
HEV (administered intravenously). The protective and cross-protective abilities of these antigens were determined following swine genotype 3 challenge by evaluating both serum and fecal samples for
HEV RNA using nested RT-PCR and IgG anti-
HEV using ELISA. The results from these two studies have important implications for future development of an effective
HEV vaccine.
As a part of our ongoing efforts to search for potential animal reservoirs for
HEV, we tested goats from Virginia for evidence of
HEV infection…

▼ Hepatitis E virus (
HEV), the causative agent of hepatitis E, is an emerging virus of global distribution. At least four distinct genotypes of
HEV exist worldwide: genotype 1 and 2
HEV strains are responsible for waterborne epidemics; genotype 3 and 4
HEV strains are responsible for sporadic occurrences of acute hepatitis E. Genotype 3 and 4 HEVs are zoonotic and have a more expanded host range than genotypes 1 and 2 which are restricted to humans. Genotype 3 and 4
HEV isolates obtained from animal tissues are genetically very similar, or identical in some cases, to human
HEV recovered from hepatitis E patients. The objectives of this dissertation research were to assess the zoonotic foodborne transmission of
HEV and elucidate the viral determinants of
HEV host range. To determine the risk of
HEV foodborne transmission, 127 packages of commercial pig liver were tested for
HEV RNA. Eleven percent of them were positive for
HEV RNA and the contaminating virus remained infectious. We also demonstrated that medium-to-rare cooking condition (56°C) does not completely inactivate
HEV, although frying and boiling of the contaminated livers inactivated the virus. To reduce the risk of foodborne
HEV transmission, commercial pig livers must be thoroughly cooked for consumption. To determine the host range of genotype 4 HEVs, pigs were inoculated with a genotype 4 human
HEV. All pigs developed an active
HEV infection indicating that genotype 4 human HEVs can cross species barriers and infect pigs. To identify viral determinant(s) of species tropism, ORF2 alone or in combination with its adjacent 5′ junction region (JR) and 3′ non-coding region (NCR), were swapped between genotypes 1 and 4, 3 and 4, and 1 and 3 to produce 5 chimeric viruses. Chimeric viruses containing ORF2 or JR+ORF2+3' NCR from genotype 4 human
HEV in the backbone of genotype 3 swine
HEV were viable in vitro and infectious in vivo. Chimeric viruses containing the JR+ORF2+3'NCR of genotypes 3 or 4
HEV in the backbone of genotype 1 human
HEV were viable in vitro but non-infectious in pigs, suggesting that ORF1 may also be important for host range.

▼ About one fifth of the energy used today is allocated in the transportation sector and most of the vehicles are driven by internal combustion engines. Replacing them with electrical machine would have a positive environmental impact but there is room for improvement of the electric machines.Rotors of the electrical machines in the automotive industry today are built with permanent magnets. High efficiency and high power density are two advantages with this machine design but there are a number of drawbacks as well. Temperature sensitivity and costly materials are two examples. Operation in higher temperature can lead to demagnetization of the magnets. Segmentation, leading to reduced heat generation, is used today to prevent overheating. By varying the composition of the magnet they also become more temperature resilience but this is often expensive.The goal with the thesis was to, by cooling, achieve and maintain a safe operation temperature while simultaneously allow higher performance and/or simpler magnet design alternatively lower temperature grade. The analysis is based on theoretical calculations and experimental results from a test rig that was designed and constructed within the thesis.The cooling system was designed to spray oil on the inside of the rotor of the electrical machine. Due to the high rotational speed the oil forms a thin film that absorbs the heat generated by the magnets. In the thesis a cylinder with an external heat source was used to simulate the rotor.A thermal analysis of the test setup was conducted to assess the heat transfer capability of the spraying method. Losses and operation temperature of an actual machine were estimated for different operation points and segmentation designs of the magnets. The results showed significant drop in the temperature of the magnets as well as a possibility to reduce the number of segments.

▼ As requirements related to vehicle fuel economy and emissions continue to
increase, automakers are developing complex hybrid powertrain control systems to meet
these requirements. With the increase in powertrain complexity and performance
requirements of a hybrid vehicle, embedded control systems have become an integral part
of these vehicles. A hybrids ability to recapture energy normally lost as heat during
braking situations can account for an increase in efficiency of up to 28%. This study
explores the use of a grade adaptive regeneration strategy for improving a hybrid
vehicles energy recapture capability. The concept of the grade adaptive regeneration
strategy was developed using a computer aided simulation model and then implemented
on the Mississippi State University Challenge X hybrid vehicle. The real-time
performance of the system was evaluated through chassis dynamometer and on-road
tests. Substantial improvements over the native hybrid control strategy, including fuel-economy
and energy recapture, have been achieved.

▼ A full vehicle model is created in Autonomie to represent a production extended range electric vehicle (EREV), specifically including the high voltage battery pack which is validated in dynamic operation against experimental data. Vehicle data is utilized as comparative input to a thermal equivalent circuit model developed analytically which aims to capture and understand the heat propagation from the cells through the entire pack, to and from the environment. The inclusion of production hardware and the liquid battery thermal management system components into the physical model considers detail geometric properties to calculate thermal resistances of components (conduction, convection and radiation) along with their associated thermal capacitances. Analog equivalent circuit simulations using PSPICE are compared to experimental results in order to validate internal temperature nodes and the heat rate through various elements with heat flux sensors; all used to refine the model. The solar data, diurnal temperature and terrain are included in the simulations to model the effects of gradient, convection and road radiation on the battery pack; both stationary and through drive cycles.
The thermal equivalent circuit accurately quantifies the heat flow dynamics of the battery. Convection and radiation sources primarily influenced the baseplate and underbody shield components whereas cell heat propagation was closely linked to cell retention frame hardware details. The distribution of cooling indicated close to 90% was directed to the cell while the remaining 10% went to the surrounding hardware. Modeling a quiescent background cooling showed the ability to reduce the diurnal temperature effects on the battery pack at the 50 watt level. The addition of insulation in key areas delineated the ability to reduce initial cell temperatures for all drive cycles, while a miniscule amount added between the cell and retention frame interface showed increased cooling capacity directed towards the cells nearing 100%. The models developed incorporated many elements which were neglected or highly simplified in all previous works and the methodology developed highlights an ability to generate accurate dynamic results with little computational power. This is a prerequisite to enable predictive controls and accurate onboard system diagnostics to extend the pack???s operational life.

▼ This thesis presents three optimization-based powertrain control methods for powertrain control of multi-mode hybrid electric vehicle, as part of the “Next-Generation Energy Technologies for Connected and Automated On-Road Vehicles (NEXTCAR)” project.
The control methods are Instantaneous Optimization, Global Optimization and Receding Horizon Control/Model Predictive Control. The Instantaneous Optimization utilizes ECMS method to determine the best operating points and best mode for powertrain control. Dynamic Programming (DP) is used in the global optimization method for optimal control. The experimentally determined mode shift fuel and electricity costs are incorporated in the algorithm to optimize the mode selection and power-split. The Receding Horizon Control utilizes the Dynamic Programming algorithm to create optimal solution within a moving prediction horizon, which has the potential for real time control.

▼ Low carbon economy and clean renewable energy now become significant topics over the world, due to the increasing demands for energy, decreasing amount of non-renewable energy, such as petrol, coal and natural gas, as well as environmental problems. With the economic development and the improvement of living standards, there is a growing emphasis on the development and utilization of water, wind, solar and other renewable energy. Comparing with the traditional energy, these new forms of energy have many advantages. However, they are subject to the climate and weather, and their output energy peaks do not match the demand. In addition, energy supply often shows big fluctuations. As a result, energy storage devices with high performance are urgently required to use energy more efficiently.
Among all the energy storage devices, lithium ion batteries exhibit much more advantages, such as high voltage, high energy density, etc., thus they have been quite popularly used in portable devices since their birth, and now they are nominated as new energy source for vehicles. In order to expand the application of lithium-ion batteries in portable electronic devices and hybrid electric vehicles, we need to improve the cycling performance, rate capability and safety performance of lithiumion batteries. Graphene, as a two-dimensional macromolecular sheet of carbon atoms with a honeycomb structure, has excellent electronic conductivity and mechanical properties, and may be the ideal conductive additive for hybrid nanostructured electrodes. Other advantages of graphene include high surface area (theoretical value of 2630 m2/g) for improved interfacial contact and the potential for low manufacturing costs. Its excellent conductivity could enhance the kinetic properties and rate performance of electrode materials. Meanwhile, the unique two-dimensional structure of the graphene can anchor, wrap and weave the nanomaterials, forming a hybrid random 3D structure. This kind of loose structure could buffer the volume expansion and avoid the agglomeration during the cycling. Furthermore, it may absorb the electrolyte, offering the special ion channels between the different nanoparticles to further improve its conductivity.
A series of graphene composites have been synthesized. The preparation, characterization and electrochemical performance of various nanostructured electrode materials are investigated.

▼ Since 2014, Formula 1 racing cars have been equipped with a hybrid electric power unit composed of an electrically turbocharged internal combustion engine and an electric motor used for boosting and regenerative braking.
The energy management system that controls this hybrid electric powertrain strongly influences the achievable lap time, as well as the consumption of fuel and battery energy.
In this thesis we study models and control strategies to achieve the best possible lap time. First, we identify a convex model of the power unit and use it to numerically assess the time-optimal control strategies. Second, we leverage the convex model to analytically derive a time-optimal control policy that can be implemented on the ECU in a feedforward fashion and in compliance with the sporting regulations. Third, we develop two feedback control algorithms to counteract disturbances and track the optimal strategies in a lap-time-optimal way: the first one in the form of a two-level optimality tracking MPC scheme, and the second one inspired by ECMS and consisting of PID controllers continuously adjusting the optimal control policy in real-time.
We perform numerical tests using convex and high-fidelity simulation environments to validate the optimality and the robustness of the proposed control approaches under realistic disturbances.

▼ Examensarbetet gjordes på Volvo Group Trucks Technology. Målet med arbetet var att studeravärmeutveckling i Li-jon cell för hybrid- och elbilar, HEV och EV. Battericeller undersöktesunder sina normala arbetsförhållanden och vid förstörande prov. Undersökningen baserades påcellernas yttemperatur. Arbetet beskrev cellernas beteende och syftade att vara ett underlag förkonstruktörer av batterisystem.En litteraturstudie gjordes för att studera faktorer som påverkar värmeutvecklingen. Sedananalyserades källor till samtliga faktorer. En moduleringsmetod för analys av cellensvärmeeffektivitet togs fram. Miljöpåverkan och ekonomiska aspekter av batterier undersöktes.Tre tester togs fram för att undersöka värmeutvecklingsfaktorer på fem celler. De flestafaktorerna var externa såsom laddning och urladdning, puls och kontinuerlig ström ochomgivningstemperatur. En infraröd kamera användes vid experimenten.Testerna visade hur olika faktorer påverkade cellernas temperatur. Vidare analys av källor visadekritiska områden i cellernas konstruktion.Förstörande värmeprov gjordes på tre par av celler. Dessa värmdes upp till 300°C vilketorsakade ”thermal runaway”. I vissa fall gick temperaturen över 600°C och celler fattade eld.Olika kemiska sammansättningar och uppbyggnad av cellerna gjorde att de betedde sig olika vidgenomförda tester.Testerna visade att olika celler presterade olika vid liknande testförhållanden. Därför är detviktigt att ta fram specifikationer för användningsförhållanden för att välja ut en cell för ettbatterisystem. Sedan kan prestandan av olika celler jämföras och effektivitet kan utvärderas församma belastningscyklar.Thermal Management System kan förhöja batteriets effektivitet och måste designas medanvändningsförhållanden i åtanke. Batteriernas säkerhet är väldigt viktig och människor får inteskadas av batterier. Därför måste säkerheten finnas i åtanke i alla steg av batteridesign.Arbetets resultat blev en sammanfattning av viktiga faktorer och specifikationer för batteridesignsom baserades på värmeutvecklingen. Samtliga riktlinjer sammanfattades i Appendix 5.
Master thesis work was done at Volvo Group Trucks Technology. Aim of the project was tostudy thermal behaviour of Li-ion battery for hybrid and electric vehicles, HEVs and EVs.Battery cells were tested in regular working conditions and abuse conditions. Surfacetemperature of cells was chosen for studying heat evolution.A literature study was conducted to research factors that influence cell temperature. Analysis ofsources of these factors was then performed. A modelling method for analyzing cell thermalefficiency was designed. Sustainability and economics aspects of batteries were also studied.When factors were established three tests were designed to study their effects. Five cells werestudied. Tests mainly examined external factors such as charge and discharge, pulse andcontinuous current, ambient temperature to name a few.

▼ A Hybrid Electric Vehicle (
HEV) is a complex electro-mechanical-chemical system that involves two or more energy sources. The inherent advantages of HEVs are their increased fuel economy, reduced harmful emissions and better vehicle performance. The extent of improvement in fuel economy and vehicle performance greatly depends on selecting optimal component sizes. The complex interaction between the various components makes it difficult to size specific components manually or analytically. So, simulation-based multi-variable design optimization is a possible solution for such kind of system level design problems. The multi-modal, noisy and discontinuous nature of the Hybrid Vehicle design requires the use of derivative-free global algorithms because the derivative-based local algorithms work poorly with such design problems.
In this thesis, a Hybrid Vehicle is optimized using various Global Algorithms ? DIviding RECTangles (DIRECT), Simulated Annealing (SA), Genetic Algorithm (GA), and Particle Swarm Optimization (PSO). The objective of this study is to increase the overall fuel economy on a composite of city and highway driving cycle and to improve the vehicle performance. The performance of each algorithm is compared on a six variable hybrid electric vehicle design problem. Powertrain System Analysis Tool (PSAT), a state-of-the-art powertrain simulator, developed in MATLAB/Simulink environment by Argonne National Laboratory is used as the vehicle simulator. Further, a Hybrid algorithm that is a combination of global and local algorithm is developed to improve the convergence of the global algorithms. The hybrid algorithm is tested on two simple mathematical functions to check its efficiency.

▼ Olověné akumulátory jsou nejběžněji používanými elektrochemickými zdroji proudu. Olověný akumulátor je nejstarším typem sekundárních článků. Velké využití mají u hybridních elektrických vozidel (
HEV), kde pracují v různých režimech provozu vozidla. S tím souvisí i změny teploty akumulátoru, které jsou způsobeny Jouleovým teplem při vybíjení a nabíjení akumulátoru v určitém režimu provozu vozidla. Olověné akumulátory v hybridních elektrických vozidlech pracují v režimu částečného nabití PSoC.; The lead-acid batteries are most commonly used electrochemical power source. The lead-acid battery is the oldest type of secondary battery cells. This lead-acid batteries have a great use in hybrid electric vehicles (HEVs), which operate in different modes of vehicle operation. This is related to changes in battery temperature, caused by Joule heat taking place during discharging and chargingg the battery in a vehicle operation. The lead-acid batteries in hybrid electric vehicles work in mode PSoC.
