▼ A handling quality investigation was performed on
the swept gull-wing configuration. The swept gull-wing
configuration is tailless and has a wing with a transition in the
sweep and dihedral angle. An example of this type of aircraft is
the Exulans. This aircraft is currently under development at the
University of Pretoria. The handling quality study was focussed on
pitch axis dynamics. The Exulans is a research testbed that will be
used to investigate the swept gull-wing configuration and its
special controls by means of full-scale flight testing.
Variable
wing sweep, twisting elevons and winglets will be investigated as
means of control. These control devices are configured in such a
way as to have minimum impact on the performance of the aircraft.
The handling qualities of the swept gull-wing configuration have to
be acceptable while using these different control strategies. The
study was launched to investigate whether a gull-wing configuration
aircraft will have satisfactory handling qualities at CG positions
associated with the most favourable aerodynamic performance. There
is an aerodynamic performance gain in designing an aircraft so that
the CG falls on the so-called `E-point'. The E-point is the centre
of pressure for an elliptical circulation distribution. An
elliptical circulation distribution is associated with the highest
Oswald efficiency for an aircraft. Time domain simulation
techniques and frequency domain analysis techniques were used to
analyse the handling qualities of the gull-wing configuration. The
C-star criterion was used to analyse handling qualities with time
domain simulation data as input. Comparative time domain
simulations were performed between the Exulans and other aircraft
to compare handling qualities. Eigenvalue analysis was used
together with the thumbprint criterion to investigate inherent
gull-wing airframe dynamics. The Shomber-Gertsen and Military
Specification 8785 criteria were also used for the same purpose.
The Neal-Smith method was used to investigate the effect of control
authority on handling qualities and the effect of a pilot. The
Monnich and Dalldorff criterion was used to evaluate gust handling
qualities. An analysis chart by Fremaux and Vairo was used to
evaluate the tumbling susceptibility of the gull-wing
configuration. The pitch handling quality investigation shows
sufficient promise that the swept gull-wing configuration will have
acceptable handling qualities with the CG placed at positions
associated with optimised aerodynamic performance. Analysis showed
that the swept gull-wing configuration is potentially prone to
tumbling. With low
static margins, the configuration should exhibit
improved handling qualities in gusty conditions when compared to
existing tailless aircraft. It is recommended that a lateral
handling quality study be performed before full scale flight
testing commences on the Exulans. In addition, the possibility of
wingtip stall must be investigated for the case of the swept
gull-wing configuration.

▼ With the continuous miniaturization of CMOS technology into the nanometer regime, the reliability of SRAM memories is threatened by accelerated transistor aging such as Bias Temperature Instability (BTI), Hot Carrier Injection (HCI) and gate oxide breakdown. Among these mechanisms BTI is known to be the primary aging mechanism in nanoscale devices. The overall effect of BTI is a gradual increase of threshold voltage (Vth). BTI significantly reduces the Static Noise Margin (SNM) of an SRAM cell and makes it more susceptible to failures. To address the impact of BTI in memory array a variety of bit flipping techniques has been proposed. However, all the proposed bit flipping techniques require at least an additional column to store the inversion flag which imposes considerably large area overhead. In this thesis, we propose two techniques to mitigate BTI induced aging in embedded memory: aging-aware instruction encoding and self-controlled bit flipping; both schemes take the workload into consideration. The aging-aware instruction encoding technique is based on changing the encoding of the Instruction Set Architecture (ISA) in order to balance the occurrence probabilities of 1s and 0s and therefore minimize the impact of BTI in the embedded memory. To evaluate this scheme, we used the Leon2 processor for course case study. A C++ based simulation environment was used to exhaustively search for an encoding resulting in a balanced occurrence probabilities of 0s and 1s. The simulation results revels that on average up to 30% SNM degradation improvement. Self-controlled bit flipping is based on inverting the content of the memory array during write operation with respect to a specific bit of the written word referred to as flip bit; this bit is left untouched during the write and used as a reference bit to indicate either the written data is inverted or not. Simulation results show that up to 33% SNM degradation improvement can be achieved. The area overhead of the proposed technique is the flip circuitry only. For this reason, our technique saves 64% of the area overhead induced by the periodic flipping techniques.

▼ The most widely used design for a memory cell in
Static Random-Access Memory (SRAM) today is the 6T bit cell, which uses six transistors to store a single bit of binary data. This project was aimed at investigating a new structure proposed for SRAM bit cells [9], which uses seven transistors to save power, and comparing it to the traditional 6T SRAM bit cell. The criteria used to evaluate performance included the write and read times, the amount of power consumed, and the
static noise
margin (SNM) for both bit cell designs. Simulations were run for worst-case operating conditions with a slow-slow process, high temperature, and low voltage supply, as well as for other process, supply voltage and temperature (PVT) conditions.

▼ Technology scaling has been the most obvious choice of designers and chip
manufacturing companies to improve the performance of analog and digital circuits.
With the ever shrinking technological node, process variations can no longer be ignored
and play a significant role in determining the performance of nanoscaled devices. By
choosing a worst case design methodology, circuit designers have been very munificent
with the design parameters chosen, often manifesting in pessimistic designs with
significant area overheads.
Significant work has been done in estimating the impact of intra-die process
variations on circuit performance, pertinently, noise
margin and standby leakage power,
for fixed transistor channel dimensions. However, for an optimal, high yield, SRAM cell
design, it is absolutely imperative to analyze the impact of process variations at every
design point, especially, since the distribution of process variations is a statistically
varying parameter and has an inverse correlation with the area of the MOS transistor.
Furthermore, the first order analytical models used for optimization of SRAM memories
are not as accurate and the impact of voltage and its inclusion as an input, along with
other design parameters, is often ignored.
In this thesis, the performance parameters of a nano-scaled 6-T SRAM cell are
modeled as an accurate, yield aware, empirical polynomial predictor, in the presence of
intra-die process variations. The estimated empirical models are used in a constrained
non-linear, robust optimization framework to design an SRAM cell, for a 45 nm CMOS
technology, having optimal performance, according to bounds specified for the circuit
performance parameters, with the objective of minimizing on-chip area. This statistically aware technique provides a more realistic design methodology to study the trade off
between performance parameters of the SRAM.
Furthermore, a dual optimization approach is followed by considering SRAM
power supply and wordline voltages as additional input parameters, to simultaneously
tune the design parameters, ensuring a high yield and considerable area reduction. In
addition, the cell level optimization framework is extended to the system level
optimization of caches, under both cell level and system level performance constraints.

▼ Aggressive technology scaling in semiconductor devices
has resulted in stability reduction for classic SRAM designs. This
is especially problematic for large integrated circuits. The
stability of SRAM cells can be affected by noise during a read
operation and radiation during the standby mode. In this work, an
approach to address the gradual stability reduction in SRAM designs
is presented. An SRAM design trade-offs approach is presented which
improves the characteristics of SRAM by modulating the transistor
sizing ratio, β. This method was tested on various SRAM designs in
32 nm technology. SRAM designs were optimized for various
constraints in power consumption, performance, radiation tolerance
and data stability. Different design trends produced by the
extensive approach analysis is discussed in this
thesis.

▼ One of the key challenges in scaling beyond 10nm technology node is device-to-device variation. Variation in device performance, mainly threshold voltage (VT) inhibits supply voltage (VCC) scaling. In this work, a comprehensive study of process variations and line edge roughness (LER)/sidewall roughness (SWR) effects in advanced CMOS devices
namely Silicon (Si) Bulk n-/p-FinFETs, In0.53Ga0.47As Bulk n-FinFETs, Germanium (Ge) Bulk p-FinFETs and Gallium Antimonide-Indium Arsenide (GaSb-InAs) staggered-gap Heterojunction n-/p-Tunnel FETs (HTFETs) is presented. This study is done using three-dimensional (3D) Technology Computer Aided Design (TCAD) numerical simulations. According to the sensitivity study, FinFET and Tunnel FET (TFET) device parameters are highly susceptible to �n width, WFIN, and ultra-thin body thickness, Tb,
variations, respectively. Moreover, TFETs show higher variation in device than FinFETs. Additionally, a Monte Carlo study of SWR variation on n- and p-FinFETs show higher 3sigma�(VTLin) of In0.53Ga0.47As Bulk n- and Ge Bulk p-FinFETs than their Si counterparts. Further, to study the variation impact on memory circuits, we also simulate 6T and 10T SRAM cells with FinFETs and HTFETs, respectively.
Another key challenge with advanced CMOS devices is time-dependent VT degradation due to BTI reliability. Thus, in the second part of this work, a comparative study of Positive Bias Temperature Instability (PBTI) reliability on n-type III-V devices and Negative Bias Temperature Instability (NBTI) reliability on p-type Ge devices is presented. PBTI reliability is studied in InxGa1

▼ Este trabalho teve como objetivo discutir a temática do Custeio Variável aplicado a uma empresa prestadora de serviços, para demonstrar o uso da Margem de Contribuição como ferramenta de apoio à gestão da empresa. A pesquisa aqui relatada utilizou o método qualitativo como abordagem, realizada por meio de um estudo de caso descritivo utilizando como modelo a Análise da relação Custo x Volume x Lucro para empresas multiprodutoras. A fim de possibilitar a realização deste estudo de caso, foi realizada a revisão da literatura sobre o tema, de modo a fundamentar e estruturar as etapas de aplicação do modelo adotado no ambiente organizacional escolhido, analisando-se os serviços prestados pela empresa e identificando-se corretamente a Margem de Contribuição destes. Após esta etapa, foi possível analisar a participação de cada serviço na composição do mix de vendas da empresa e, dessa forma, avaliar a contribuição efetiva de cada um na geração da riqueza para a empresa. O modelo proposto envolve basicamente a identificação da Margem de Contribuição Unitária e sua correspondente Razão de Contribuição, além da identificação do Ponto de Equilíbrio de cada serviço, bem como da empresa como um todo. Esse estudo foi desenvolvido em uma instituição de ensino em fase de crescimento e devido aos desafios que se apresentam a uma empresa nessas condições, aumenta a relevância do mesmo, do ponto de vista do uso de ferramentas de gestão profissionais, que apesar de consagradas no mercado, nem sempre são utilizadas por uma grande parte das pequenas empresas. Ao final, é demonstrada a aplicação do modelo e destacada a sua relevância para a gestão da empresa, bem como, apresentadas as conclusões do estudo, evidenciando-se que por meio da utilização do modelo proposto, os objetivos específicos são atingidos e a indagação feita a cerca da problemática discutida é respondida por meio dos resultados obtidos no presente estudo.
This study aimed to discuss the theme of Variable Costing applied to a service provider, to demonstrate the use of the Contribution Margin as a management support tool company. The research reported here used the qualitative method as approach, performed through a descriptive case study using a model of Analysis of Cost x Volume x Profit respect to multiproducts companies. In order to enable the realization of this case study, the literature review on the subject was held in order to support and structure the application steps of the model adopted in the organizational environment chosen by analyzing the services provided by the company and the correct identification of the contribution margin of these. After this step, it was possible to analyze the participation of each service in the composition of the sales mix of the company and thus evaluate the actual contribution of each in the generation of wealth for the company. The proposed model basically involves identifying the unit contribution margin and it’s corresponding contribution ratio and the identification Breakeven Point each service as well as the company…

▼ Ce manuscrit étudie dans un premier temps la dépendance de la distorsion, ou erreur en quantification, du quantificateur construit à partir d'un n-échantillon d'une distribution de probabilité via l'algorithme des k-means. Plus précisément, l'objectif de ce travail est de donner des bornes en probabilité sur l'écart entre la distorsion de ce quantificateur et la plus petite distorsion atteignable parmi les quantificateurs, à nombre d'images k fixé, décrivant l'influence des divers paramètres de ce problème: support de la distribution de probabilité à quantifier, nombre d'images k, dimension de l'espace vectoriel sous-jacent, et taille de l'échantillon servant à construire le quantificateur k-mean. Après un bref rappel des résultats précédents, cette étude établit l'équivalence des diverses conditions existantes pour établir une vitesse de convergence rapide en la taille de l'échantillon de l'écart de distorsion considéré, dans le cas des distributions à densité, à une condition technique ressemblant aux conditions requises en classification supervisée pour l'obtention de vitesses rapides de convergence. Il est ensuite prouvé que, sous cette condition technique, une vitesse de convergence de l'ordre de 1/n pouvait être atteinte en espérance. Ensuite, cette thèse énonce une condition facilement interprétable, appelée condition de marge, suffisante à la satisfaction de la condition technique établie précédemment. Plusieurs exemples classiques de distributions satisfaisant cette condition sont donnés, tels les mélanges gaussiens. Si cette condition de marge se trouve satisfaite, une description précise de la dépendance de l'écart de distorsion étudié peut être donné via une borne en espérance: la taille de l'échantillon intervient via un facteur 1/n, le nombre d'images k intervient via différentes quantités géométriques associées à la distribution à quantifier, et de manière étonnante la dimension de l'espace sous-jacent semble ne jouer aucun rôle. Ce dernier point nous a permis d'étendre nos résultats au cadre des espaces de Hilbert, propice à la quantification des courbes. Néanmoins, la quantification effective en grande dimension nécessite souvent en pratique une étape de réduction du nombre de variables, ce qui nous a conduit dans un deuxième temps à étudier une procédure de sélection de variables associée à la quantification. Plus précisément, nous nous sommes intéressés à une procédure de type Lasso adaptée au cadre de la quantification vectorielle, où la pénalité Lasso porte sur l'ensemble des points images du quantificateur, dans le but d'obtenir des points images parcimonieux. Si la condition de marge introduite précédemment est satisfaite, plusieurs garanties théoriques sont établies concernant le quantificateur issu d'une telle procédure, appelé quantificateur Lasso k-means, à savoir que les points images de ce quantificateur sont proches des points images d'un quantificateur naturellement parcimonieux, réalisant un compromis entre erreur en quantification et taille du support des points images, et que l'écart…

Rörlig ersättning till VD : Hur påverkar det företagets lönsamhet?.

▼ Background: It is today common for companies to provide some sort of incentive for CEO's and senior management positions to motivate, retain and benefit employees within a company. This is in order to drive the goals of the CEO and management in the direction that is desired by the owner. Currently, the Swedish centre-right government has forbidden the use of such variable pay within state-owned companies. There are two different attitudes to variable pay, one that is in favour and one that rejects it. However most people agree on the fact that a well-functioning incentive scheme can be of great strategic importance for a company.
Approach: has variable pay to CEO's had any effect on the company's profitability.
Aim: the aim of the study is to compare companies who use variable pay to CEO's with companies that do not in relation to their profitability in terms of profit margins, yearly performance, returns on total capital and returns on equity.
Method: the study uses a quantitative approach. The statistical methods that are used to answer the research question are linear and logistic regression analyses of 51 publicly owned companies in Sweden. The statistical analyses utilises an existing database (Affärsdata) which has information based on the companies’ annual report. Due to the fact that the database lacked information concerning incentive schemes, this information was retrieved manually from the company websites (annual financial reports). The research approach is deductive as we have used a range of theories which we thereafter test through our empirical analysis.
Results: The results for the linear regressions show that variable pay to CEO has little or no connection to the degree of the company’s profitability. The logistic regressions show a positive significant relationship between variable pay and the company’s odds of being profitable or not.
Conclusion: The study shows that variable pay to the CEO is unlikely to have a big impact on the degree of profit or loss for a company. It does however show that variable pay to the CEO is of importance in terms of whether the company makes a profit or not.
Bakgrund: Det är idag vanligt att företag använder sig av någon typ av incitament till VD och ledande befattningshavare. Syftet är att motivera, behålla och gynna anställda inom ett företag. Detta för att kunna styra VD och ledningens mål i den riktning ägaren önskar. I dagsläget har den borgerliga regeringen i Sverige beslutat om att bruket av rörlig ersättning inom statligt ägda företag är förbjudet. Uppfattningar kring företags tillämpande av rörlig ersättning skiljer sig från de som helt förkastar användandet till de som fullt ut förespråkar dem. Däremot är de flesta överens om att ett fungerande incitamentsprogram kan vara av stor strategisk betydelse för ett företag.
Problemformulering: Har rörlig ersättning till VD…

▼ Taiwan Futures Exchange (TAIFEX) freezes a traderâs fund based on traditional A B
margin system when a trader place orders. Once orders are executed, the trader can stick to the old
margin system or choose the portfolio-based
margin system SPAN to calculate
margin requirements. Conventional wisdom suggests that SPAN should be adopted as SPAN will charge less
margin requirements than the traditional
margin system and maximizes
margin efficiency.
This study shows that two conditions must hold for SPAN to charge less
margin requirements than the traditional
margin system. We demonstrate by simulation that under certain situations SPAN may ask for more
margin requirements than the traditional
margin system when shorting vanilla options. Although SPAN may prove more accurately in calculating the risk for a portfolio that includes options, SPAN may not always charge less
margin requirements than the traditional
margin system. For small traders who trade one-side option market, sticking to the tradition
margin system might still be a better policy sometimes.

Holocene climate evolution of the eastern tropical Pacific

▼ The Peru
margin plays a significant role in global
climate dynamics and biogeochemical cycling. Situated between
4-15°S off the western coast of South America the Peru upwelling
region fuels one of the world's most productive marine ecosystems.
This high surface productivity along with poorly ventilated source
waters places the Peru
margin within the world's three oxygen
minimum/denitrification zones. These denitrification regions
represent the major loss of nitrate (an important macronutrient)
from the ocean system. As a consequence of this, long-term changes
in the strength and/or size of the Peru
margin upwelling system
have a fundamental impact on the world's carbon cycle. The Peru
coastal current merges with equatorial upwelling to form the
eastern equatorial cold tongue. Instability of the tropical cold
tongue drives the coupled oceanic- atmospheric El Niño Southern
Oscillation (ENSO). This coupled mode has been described as a
'globalizer' for its ability to drive global climate on both
millennial and orbital timescales. Despite the significance of the
Peru
margin, little is known about how the climate evolved during
the recent past. The work presented in this dissertation focuses on
understanding how the Peru
margin climate has evolved since the end
of the Last Glacial Maximum, and identifying what the driving
mechanisms of those climate changes were. Here we reconstruct the
key environmental parameters of the Peru
margin climate:Sea surface
temperature (UK'37 index), phytoplankton productivity
(Alkenone-C37total and biogenic silica and subsurface ventilation
(δ15N of bulk organics). Our results suggest that the remote
ventilation of the Peru thermocline dominated over the oxygen
demand imposed by local productivity during the early Holocene.
Near the middle Holocene a dramatic increase in climate variability
was accompanied by a shift toward more locally driven climate
dynamics, revealed through the relationship between our surface and
subsurface climate proxies. The late Holocene section of our record
oscillates between centennial-scale periods of locally driven and
non-locally driven subsurface ventilation. We therefore argue that
the strength of the Peru oxygen minimum zone reflects a balance
between high and low latitude climate forcings.

▼ O objetivo deste trabalho foi analisar se os investimentos em parte dos municípios brasileiros em usinas de geração de energia elétrica impactaram o PIB dos respectivos municípios. Consideraram-se, para esse importante setor de infraestrutura, as fontes de geração eólica, térmica e hidráulica, no período de 2005 a 2010, dentro de 5.558 municípios no Brasil, excluídas seis em função de inexistência de todos os dados. Os resultados empíricos deste trabalho mostram evidências de que a implantação de usinas de geração de energia elétrica em parte dos municípios, principalmente as usinas térmicas, tem efeito positivo sobre o PIB dos respectivos municípios. Considerando a variável espacial, distância, os resultados indicam
que os municípios que estão a pelo menos 1.000 km de distância do local onde foi implantado o empreendimento, também recebem benefícios no roduto interno. Este resultado foi identificado, também, pela análise empírica demonstrada no painel de dados estático de efeitos fixos. A regressão realizada em painel de dados dinâmico de Arellano-Bond também confirma o resultado.
The aim of this study was to analyze whether investment in part of Brazilian municipalities in power generation plants had an impact on GDP of the respective municipalities. Considering, in this important infrastructure sector, both sources of wind generation, thermal and hydraulic, in the period 2005-2010, in 5,558 counties in Brazil, six were excluded due to lack of any
data. The empirical results of this study show evidence that the creation of plants generating electricity in the counties, especially thermal power plants, has a positive effect on GDP in the respective counties. Considering the spatial variable, distance, the results indicate that counties are at least 1,000 miles away from where the project was implemented, also a recent benefit of domestic product. This result was identified also by empirical analysis demonstrated in the static panel of fixed data effects. The regression performed on dynamic Arellano-Bond panel data also confirms the result.

▼ Dynamic dead variable analysis (DDVA) extends traditional static dead variable analysis (SDVA) in the context of model checking through the use of run-time information. The analysis is run multiple times during the course of model checking to create a more precise set of dead variables. The DDVA is evaluated based on the amount of memory used to complete model checking relative to SDVA while considering the extra overhead required to implement DDVA. On several models with a complex control flow graph, DDVA reduces the amount of memory needed by 38-88MB compared to SDVA with a cost of 36 bytes of memory verhead. On several models with loops, DDVA achieved no additional reduction compared to SDVA while requiring no more memory than SDVA.

▼ Certain applications require digital electronics to operate under extreme conditions e.g., large swings in ambient temperature, very low supply voltage, high radiation. Such applications include sensor networks, wearable electronics, unmanned aerial vehicles, spacecraft, and energyharvesting systems. This dissertation splits into two projects that study digital electronics supplied by ultra-low voltages and build an electronic system for extreme temperatures. The first project introduces techniques that improve circuit reliability at deep subthreshold voltages as well as determine the minimum required supply voltage. These techniques address digital electronic design at several levels: the physical process, gate design, and system architecture. This dissertation analyzes a silicon-on-insulator process, Schmitt-trigger gate design, and asynchronous logic at supply voltages lower than 100 millivolts. The second project describes construction of a sensor digital controller for the lunar environment. Parts of the digital controller are an asynchronous 8031 microprocessor that is compatible with synchronous logic, memory with error detection and correction, and a robust network interface. The digitial sensor ASIC is fabricated on a silicon-germanium process and built with cells optimized for extreme temperatures.

▼ Aggressive scaling of CMOS technology in sub-90nm nodes has created huge challenges. Variations due to fundamental physical limits, such as random dopants fluctuation (RDF) and line edge roughness (LER) are increasing significantly with technology scaling. In addition, manufacturing tolerances in process technology are not scaling at the same pace as transistor's channel length due to process control limitations (e.g., sub-wavelength lithography). Therefore, within-die process variations worsen with successive technology generations. These variations have a strong impact on the maximum clock frequency and leakage power for any digital circuit, and can also result in functional yield losses in variation-sensitive digital circuits (such as SRAM). Moreover, in nanometer technologies, digital circuits show an increased sensitivity to process variations due to low-voltage operation requirements, which are aggravated by the strong demand for lower power consumption and cost while achieving higher performance and density. It is therefore not surprising that the International Technology Roadmap for Semiconductors (ITRS) lists variability as one of the most challenging obstacles for IC design in nanometer regime.
To facilitate variation-tolerant design, we study the impact of random variations on the delay variability of a logic gate and derive simple and scalable statistical models to evaluate delay variations in the presence of within-die variations. This work provides new design insight and highlights the importance of accounting for the effect of input slew on delay variations, especially at lower supply voltages. The derived models are simple, scalable, bias dependent and only require the knowledge of easily measurable parameters. This makes them useful in early design exploration, circuit/architecture optimization as well as technology prediction (especially in low-power and low-voltage operation). The derived models are verified using Monte Carlo SPICE simulations using industrial 90nm technology.
Random variations in nanometer technologies are considered one of the largest design considerations. This is especially true for SRAM, due to the large variations in bitcell characteristics. Typically, SRAM bitcells have the smallest device sizes on a chip. Therefore, they show the largest sensitivity to different sources of variations. With the drastic increase in memory densities, lower supply voltages and higher variations, statistical simulation methodologies become imperative to estimate memory yield and optimize performance and power. In this research, we present a methodology for statistical simulation of SRAM read access yield, which is tightly related to SRAM performance and power consumption. The proposed flow accounts for the impact of bitcell read current variation, sense amplifier offset distribution, timing window variation and leakage variation on functional yield. The methodology overcomes the pessimism existing in conventional worst-case design techniques that are used in SRAM design. The proposed…

▼ This dissertation consisits of two chapters. Both chapters relate to the effects of trade resistence measures commonly used in the International Trade literature. The first chapter investigates the effects of trade costs on the extensive and intensive margins of trade. The second chapter uses a semi-nonparametric estimation technique to include zero trade trade values and adds additional flexibility to the estimation of trade costs. Trade literature has made use of the gravity equation since its introduction by Tinbergen (1962) to measure the impact of trade barriers and country characteristics on bilateral trade flows. The new focus of the literature separates international trade into two separate components: 1) the extensive
margin which describe the variety of products exported, and 2) the intensive
margin which describes the volume of each variety exported. Research using the traditional gravity equation inherently assumes that for any change in trade cost only affects the intensive
margin or
variable costs. Industry level data is used to construct a modified gravity specification that allows for the separate analysis of the extensive and intensive
margin as well as their specific contribution to the estimates of trade costs. It is shown that the extensive
margin or fixed costs do have significant contribution to the estimates in previous research using the gravity equation. Additionally, the changing nature of trade costs investigated in past research will be shown to be in part due trade resistance measures increasing or decreasing on the intensive
margin. Recently, there has been increased interest in estimation techniques that allow for the presence of zeros for determining the impact covariates on international trade flows. Traditionally, the gravity equation has been used to measure trade resistance and geographic characteristics on bilateral trade. Recent methods have tried to correct for selection and heterogeneity bias created by the use of Ordinary Least Squares (OLS). Allowing zero trade values in the estimation process allows for the inclusion potentially useful information in the determination of the effects of trade costs on bilateral trade. This paper will use a semi-nonparametric estimation that will correct for selection and heterogeneity bias. Conditional density estimation (CDE) is a semi-nonparametric approach that allows for the inclusion of bilateral pairs with no observed trade and for an accurate estimate of the change in the expected value of trade given a change in the explanatory
variable. The CDE method is a discrete approximation of the density function that mimics a discrete hazard rate analyses on the
variable of interest conditional of the explanatory variables. The estimates of geographic distance and GDPs of each country are shown to be lower using the CDE than the standard gravity method of estimation.

Tumor invasion margin from diffusion weighted

▼ Glioma is one of the most challenging types of brain
tumors to be treated or controlled locally. One of the main
problems is to determine which areas of the apparently normal brain
contain glioma cells, as gliomas are known to infiltrate several
centimetres beyond the clinically apparent lesion that is
visualized on standard CT or MRI. To ensure that radiation
treatment encompasses the whole tumor, including the cancerous
cells not revealed by MRI, doctors treat the volume of brain that
extends 2cm out from the margin of the visible tumor. This approach
does not consider varying tumor-growth dynamics in different brain
tissues, thus it may result in killing some healthy cells while
leaving cancerous cells alive in other areas. These cells may cause
recurrence of the tumor later in time which limits the
effectiveness of the therapy. In this thesis, we propose two models
to define the tumor invasion margin based on the fact that glioma
cells preferentially spread along nerve fibers. The first model is
an anisotropic reaction-diffusion type tumor growth model that
prioritizes diffusion along nerve fibers, as given by DW-MRI data.
The second proposed approach computes the tumor invasion margin
using a geodesic distance defined on the Riemannian manifold of
brain fibers. Both mathematical models result in Partial
Differential Equations (PDEs) that have to be numerically solved.
Numerical methods used for solving differential equations should be
chosen with great care. A part of this thesis is dedicated to
discuss in detail, the numerical aspects such as stability and
consistency of different finite difference methods used to solve
these PDEs. We review the stability issues of several 2D methods
that discretize the anisotropic diffusion equation and we propose
an extension of one 2D stable method to 3D. We also analyze the
stability issues of the geodesic model. In comparison, the geodesic
model is numerically more stable than the anisotropic diffusion
model since it results in a first-order PDE. Finally, we evaluate
both models on actual DTI data from patients with glioma by
comparing our predicted growth with follow-up MRI scans. Results
show improvement in predicting the invasion margin when using the
geodesic distance model as opposed to the 2cm conventional
Euclidean distance.

▼ State explosion in model checking continues to be the primary obstacle to widespread use of software model checking. The large input ranges of variables used in software is the main cause of state explosion. As software grows in size and complexity the problem only becomes worse. As such, model checking research into data abstraction as a way of mitigating state explosion has become more and more important. Data abstractions aim to reduce the effect of large input ranges. This work focuses on a static program analysis technique called dead variable analysis. The goal of dead variable analysis is to discover variable assignments that are not used. When applied to model checking, this allows us to ignore the entire input range of dead variables and thus reduce the size of the explored state space. Prior research into dead variable analysis for model checking does not make full use of dynamic run-time information that is present during model checking. We present an algorithm for intraprocedural dead variable analysis that uses dynamic run-time information to find more dead variables on-the-fly and further reduce the size of the explored state space. We introduce a definition for the maximal state space reduction possible through an on-the-fly dead variable analysis and then show that our algorithm produces a maximal reduction in the absence of non-determinism.

▼ Dentre os componentes da estratégia dos prestadores de serviços, a determinação de custos, margens e preços finais se constitui como elemento de elevada importância para manutenção da viabilidade econômica, dentro de um mercado que exige melhores serviços, com a manutenção de custos em patamares que permitam rentabilidade frente aos reembolsos e assegurem uma posição de captação e manutenção de clientes. As pequenas e médias empresas têm importante papel socio-econômico no cenário nacional, e há uma percepção de falta de práticas gerenciais adequadas no setor de medicina veterinária. Alega-se que o conhecimento contábil exerce papel central na adoção das práticas utilizadas. Desta forma, a pesquisa é conduzida no setor de serviços de clínica médica veterinária para avaliar empiricamente o nível de conhecimento contábil conceitual dos gestores, quais variáveis contingenciais e pessoais interferem no conhecimento contábil e de que forma esse conhecimento interfere nas práticas gerenciais. A bibliografia indica que o conhecimento contábil é importante variável contingente, afetando as práticas e o desempenho das organizações. A Upper Echelons Theory argumenta que uma organização é reflexo da decisão de seus gestores e que atributos pessoais observáveis do gestor podem ser utilizados como meio de influência das práticas adotadas. A pesquisa contribui para a literatura a respeito de Teoria da Contingência e Upper Echelons Theory. A metodologia aplicada nesta pesquisa foi um survey com 30 itens, divididos em blocos de identificação do perfil organizacional e pessoal do gestor, avaliação de conhecimentos contábeis e rotinas de determinação de custos, margens e preços. Foram obtidas 167 respostas cuja análise permitiu retratar um nível de conhecimento de conceitos contábeis mediano, sem o refinamento dos métodos de custeio variável, margem de contribuição e aplicação de custos na determinação de preços. O nível de conhecimento foi impactado pelas variáveis contingenciais: localização geográfica e presença de gestão profissional. Atributos pessoais do gestor que refletiram diferenças de nível de conhecimento contábil foram: formação acadêmica, grau de formação e horas de capacitação técnica em gestão. O conhecimento, quando considerado a variável contingente, foi determinante das práticas utilizadas de custo, margem e precificação. Há uma percepção de descontentamento com os próprios conhecimentos por parte dos empresários que apontam a falta de conhecimento e a falta de profissionais habilitados como os principais obstáculos para uma melhor gestão. Não houve identificação de contadores como gestores na amostra e os respondentes indicam o não oferecimento do serviço por parte do profissional contábil que os assessora como o principal motivo para o afastamento. Há indícios de que quanto maior o nível de conhecimento, melhor o desempenho financeiro e oportunidades para diferenciação. São apresentadas proposições de aproximação de profissionais contábeis capacitados e empresários, assim como sugestões e oportunidades de…

▼ A guaranteed minimum income benefit (GMIB) is a long-dated option that can be embedded in a deferred variable annuity. The GMIB is attractive because, for policyholders who plan to annuitize, it offers protection against poor market performance during the accumulation phase, and adverse interest rate experience at annuitization. The GMIB also provides an upside equity guarantee that resembles the benefit provided by a lookback option.
We price the GMIB, and determine the fair fee rate that should be charged. Due to the long dated nature of the option, conventional hedging methods, such as delta hedging, will only be partially successful. Therefore, we are motivated to find alternative hedging methods which are practicable for long-dated options. First, we measure the effectiveness of static hedging strategies for the GMIB. Static hedging portfolios are constructed based on minimizing the Conditional Tail Expectation of the hedging loss distribution, or minimizing the mean squared hedging loss. Next, we measure the performance of semi-static hedging strategies for the GMIB. We present a practical method for testing semi-static strategies applied to long term options, which employs nested Monte Carlo simulations and standard optimization methods. The semi-static strategies involve periodically rebalancing the hedging portfolio at certain time intervals during the accumulation phase, such that, at the option maturity date, the hedging portfolio payoff is equal to or exceeds the option value, subject to an acceptable level of risk. While we focus on the GMIB as a case study, the methods we utilize are extendable to other types of long-dated options with similar features.

▼ L'objectif du travail proposé est de concevoir et commander un groupe des robots mobiles similaires et d'architecture simple appelés m-bots (mono-robots). Plusieurs m-bots ont la capacité de saisir ensemble un objet afin d'assurer sa co-manipulation et son transport quelle que soit sa forme et sa masse. Le robot résultant est appelé p-bot (poly-robot) et est capable d'effectuer des tâches de déménageur pour le transport d'objets génériques. La reconfigurabilité du p-bot par l'ajustement du nombre des m-bots utilisés permet de manipuler des objets lourds et des objets de formes quelconques (particulièrement s'ils sont plus larges qu'un seul m-bot). Sont considérés dans ce travail l'évitement d'obstacle ainsi que la stabilité du p-bot incluant la charge à transporter. Une cinématique pour un mécanisme de manipulation a été proposée et étudiée. Ce dernier assure le levage de la charge et son dépôt sur le corps des robots pour la transporter. Plusieurs variantes d'actionnement ont été étudiées : passif, avec compliance et actionné. Un algorithme de positionnement optimal des m-bots autour de l'objet à manipuler a été proposé afin d'assurer la réussite de la tâche à effectuer par les robots. Cet algorithme respecte le critère de "Force Closure Grasping" qui assure la stabilité de la charge durant la phase de manipulation. Il maintient aussi une marge de stabilité statique qui assure la stabilité de l'objet durant la phase de transport. Enfin, l'algorithme respecte le critère des zones inaccessibles qui ne peuvent pas être atteintes par les m-bots. Une loi de commande a été utilisée afin d'atteindre les positions désirées pour les m-bots et d'assurer la navigation en formation, durant la phase du transport, durant laquelle chaque robot élémentaire doit maintenir une position désirée par rapport à l'objet transporté. Des résultats de simulation pour un objet de forme quelconque, décrite par une courbe paramétrique, sont présentés. Des simulations 3D en dynamique multi-corps ainsi que des expériences menées sur les prototypes réalisés ont permis de valider nos propositions.
Our goal in the proposed work is to design and control a group of similar mobile robots with a simple architecture, called m-bot. Several m-bots can grip a payload, in order to co-manipulate and transport it, whatever its shape and mass. The resulting robot is called a p-bot andis capable to solve the so-called "removal-man task" to transport a payload. Reconfiguring the p-bot by adjusting the number of m-bots allows to manipulate heavy objects and to manage objects with anyshape, particularly if they are larger than a single m-bot. Obstacle avoidance is addressed and mechanical stability of the p-bot and its payload is permanently guaranteed. A proposed kinematic architecture for a manipulation mechanism is studied. This mechanism allows to lift a payload and put it on them-bot body in order to be transported. The mobile platform has a free steering motion allowing the system maneuver in any direction. An optimal positioning of the m-bots around the…

▼ PURPOSE: The purpose of this research was to quantify the effects of a warm-up with
static or dynamic stretching on countermovement jump height, reaction time, muscle onsets for tibialis anterior (TA) and vastus lateralis (VL), and low back/ hamstring flexibility.
METHODS: Twenty one recreationally-active males (24.4 ± 4.5 yrs), recruited from the university community, completed 3 data collection sessions. Inclusion criteria were regular participation (30 minutes, 3 days per week) in exercise including resistance training, sprinting, or jumping, and no history of lower extremity injury in the past 6 months. Each session included a 5 minute treadmill jog followed by one of the stretch treatments: no stretching (NS),
static stretching (SS), or dynamic stretching (DS). After the general warm-up and treatment, the participant performed a sit-and-reach test to assess low back and hamstring flexibility. Next, the participant completed a series of ten maximal-effort countermovement jumps (CMJ), during which he was asked to jump as quickly as possible after seeing a visual stimulus (light). The onset of movement and CMJ height were determined from force plate data, and muscle onsets (TA and VL) were obtained using surface electromyography (sEMG). Ground reaction forces were recorded at 2000 Hz using a portable force plate, and filtered at 25 Hz. Outcome measures included maximal jump height, reaction time, and muscle onset (TA and VL). A repeated measures 3 (treatment) by 8 (jump) ANOVA was used to assess CMJ height. Additional outcome measures
(reaction time, muscle onsets, flexibility) were assessed using separate repeated-measures one-way ANOVA.
RESULTS: Results of the 3x8 repeated-measures ANOVA for CMJ height revealed a significant main effect of treatment (p=.004). Post hoc analysis showed significant differences between NS (41.4cm) and DS (43.0cm) (p=.0045), and between SS (41.9cm) and DS (p=.0435), but not between NS and SS (p=.4605). Analysis also
revealed a significant main effect of jump (p=.005) on CMJ height: mean jump height progressively decreased from the early to the late jumps. No significant interaction between treatment and jump was observed (p=.571). The analysis of reaction time,
TA and VL sEMG onsets showed no significant effects. Treatment also had a main effect (p<.001) on flexibility. Post hoc analysis revealed improved flexibility after both SS (p=.002) and DS (p<.001) compared with NS, with no difference in flexibility between the two treatments (p=.530).
CONCLUSION: CMJ height was significantly higher during the DS condition compared to SS and NS, with no difference between NS and SS. Additionally, reaction time and muscle onsets were not influenced by either stretch technique.
Athletes in sports requiring lower-extremity power should use dynamic stretching
techniques in warm-up to enhance flexibility while improving performance.

▼ Static correction for near-surface effects is a critical issue for onshore seismic data processing due to its significant impact on imaging the subsurface structure, especially for area with severe topographic and near-surface velocity variations. The key idea to determine
static correction is to build an accurate near-surface velocity model, which leads to several methods such as refraction statics, uphole surveys and tomostatics. Among these methods, tomostatics, which builds the near-surface velocity models using tomography, is a promising method. However, in complex near-surface areas, traditional grid tomography is often unable to determine the
static correction. This is mainly because the conflict between the need of smaller cell to describe the severe velocity variation and the increasing number of inversion unknowns which leads to solution's uncertainty.
The deformable-layer tomography (DLT) determines the complex near-surface velocity models by inverting for depth-varying velocity interfaces. Both synthetic and field data offer many cases illustrating DLT's effectiveness. The main advantage of DLT over grid tomography is that DLT builds a geologically reasonable model with less inversion unknowns, and can resolve the velocity model better with some constrains such as the result of uphole surveys, which is available in my study. Also, a reversed-velocity interface, which is common in mountainous area and has severe effect on near-surface imaging, may be better solved by DLT.
The survey area of my thesis is in the western Sichuan, China, which is mountainous and has a complex near-surface situation. Thus, I have been motivated to find whether the DLT can be a good solution to this problem. I use the DLT to build the near-surface velocity model and determine the
static correction for the area. The final velocity model produced by DLT holds close velocity-depth information compared to uphole survey, and
static correction calculated from such model shows improvement, such as an increasing level of reflection coherency on stack section.

▼ Static balancing is a useful concept to reduce operating effort in mechanisms. A statically balanced system which is designed to counterbalance a mass, is referred to as a gravity equilibrator. The potential energy in a gravity equilibrator is constant, which in most of the times is achieved by mechanical springs. Often helical springs are used, although these springs take a lot of space within the workspace of the mechanism. This paper presents the design of an adjustable gravity equilibrator using torsion bars, which saves space in the working area. Static balancing is achieved with a non-constant transmission (NCT). A new NCT design, and a general method to calculate the design parameters are presented. The stiffness of the torsion bars can be adapted by changing the active length. In this way it is possible to balance different masses with the same system.

▼ A margin account is a type of brokerage account that allows investors to buy and sell financial securities using credit. The account’s margin requirement is the amount of collateral required, from the investor, to cover the funds or securities extended by the broker to the investor. In Canada, the primary driver of an account’s margin requirement is the account’s Capital Charge [CC] which is calculated using a set of regulatory rules. The regulations are degenerate in that hundreds of valid CCs often exist for a single account. This work outlines a linear optimization model for selecting the minimal CC out of the set of valid CCs for a given margin account. The method proposed is consistent with all of the regulatory requirements and is guaranteed optimal in most cases. Relative to existing methods, the new method produced an average CC reduction of approximately 2% and displayed qualitatively better run-times.

▼ The basement rocks of North Island, New Zealand, comprise metasedimentary terranes that were accreted onto the eastern Gondwana
margin during Mesozoic subduction. Since the Oligocene, these terranes have been sitting at the leading edge of the Australian Plate, as the hanging wall of the Hikurangi subduction
margin, overriding the subducting Pacific Plate. This thesis examines the thermo-tectonic histories of the basement rocks in North Island, using fission-track and (U-Th-Sm)/He thermochronology.
In eastern North Island, thermochronological data from the basement rocks record the exhumation histories since the latest Jurassic, related to two subduction cycles. Zircon fission-track analysis yields detrital or slightly reset ages (264–102 Ma); apatite fission-track ages range from 122 to 7.9 Ma and (U-Th-Sm)/He from 33.3 to 6.0 Ma.
In central North Island, modelled thermal histories suggest that the basement rocks were exhumed to shallow levels (<2 km) of the crust in the Early Cretaceous (~150–135 Ma). This was followed by a period of reheating until ~100 Ma, which is interpreted to be the result of burial by sedimentation above the accretionary wedge. From 100 Ma, models indicate thermo-tectonic quiescence until the Late Oligocene.
During the late Cenozoic, exhumation of the basement rocks accelerated at ~27 Ma in the western
margin of the axial ranges (Kaimanawa Mountains). This acceleration in exhumation rate is interpreted to reflect the initiation of the subduction of the Pacific Plate beneath central North Island. Since the Late Oligocene, basement exhumation in the axial ranges migrated towards the trough. Modelled thermal histories indicate significant eastwards reverse faulting on the
margin-parallel Ngamatea Fault between ~27 and 20 Ma and on the Wellington-Mohaka Fault between ~20 and 10 Ma.
In contrast to the activity in the axial ranges, in western North Island, the exhumational response of the basement rocks to the Cenozoic subduction was less significant and not revealed from the present thermochronological data.
Since the Late Miocene, the exhumation rate in the axial ranges has varied significantly along-strike, lower in the centre and higher to the north and south. During the last 10 Myr, the total magnitude of exhumation has been ~4 km in the Wellington region in the south, >1 km in the Raukumara Range in the north and negligible (less than a few hundred metres) in the central axial ranges in the Hawke’s Bay region. Although the accumulation of underplated material at the basal upper plate may have contributed to the localised rock uplift and exhumation (e.g. in the Raukumara Range),
margin-normal shortening of the upper plate in the forearc of the Hikurangi
Margin has most likely dominated the unroofing process of the axial ranges.
In northwestern North Island, the Northland Allochthon, an assemblage of Cretaceous–Oligocene sedimentary rocks, was emplaced during the Late Oligocene–earliest Miocene, onto in situ Mesozoic and early Cenozoic rocks. Detrital zircon and apatite fission-track…
