Le travail présenté dans ce manuscrit est consacré à la restitution et à l’interprétation des profils verticaux derapports de mélange du chlorure d’hydrogène (HCl) et du formaldéhyde (H2CO) mesurés par l’instrumentsous ballon SPIRALE (SPectroscopie InfraRouge par Absorption de Lasers Embarqués), au cours de deuxvols effectués en région intertropicale depuis Teresina (Brésil, 5.1°S-42.9°S), le 22 Juin 2005 et le 9 Juin2008. Les problématiques scientifiques liées à l’étude de ces composés, les caractéristiques de la hautetroposphère et de la basse stratosphère intertropicale et enfin celles du spectromètre SPIRALE sontdécrites. L’étude de faisabilité de la mesure de H2CO a permis de définir la position et l’intensité de la raied’absorption la plus adéquate pour la mesure stratosphérique de ce composé (à 2912.1 et 1701.5 cm-1). Lesprofils verticaux de rapports de mélange de H2CO obtenus au cours de ces vols de SPIRALE sont présentéset comparés. Les mesures de HCl sont les premières à avoir été réalisées in situ dans la basse et moyennestratosphère intertropicale. Dans la couche de transition intertropicale, celles-ci sont utilisées en lien avecdes mesures récentes de composés à très courte durée de vie (VSLS), afin d’estimer la contribution deceux-ci au bilan du chlore stratosphérique. Dans la moyenne stratosphère, les signatures visibles sur lesprofils verticaux de HCl et sur ceux d’ozone acquis simultanément sont étudiées en lien avec l’oscillationquasi-biennale. En outre, le bon accord entre SPIRALE et l’instrument MLS du satellite Aura a permis deconforter la fiabilité de celui-ci pour la mesure de HClThe work presented in this manuscript is devoted to the retrieval and the interpretation of the mixing ratiovertical profiles of hydrogen chloride (HCl) and formaldehyde (H2CO), derived from the measurementsperformed by the SPIRALE balloon-borne instrument (SPectroscopie InfraRouge par Absorption de LasersEmbarqués) over Teresina (Brazil, 5.1°S-42.9°S), on 22 June 2005 and 9 June 2008. The scientificquestions associated with the study of these compounds, the characteristics of the tropical uppertroposphere and lower stratosphere and those of the SPIRALE spectrometer are described. The feasibilitystudy of the H2CO measurement has allowed to define the position and the intensity of the most suitableabsorption line for the stratospheric measurement of this compound (at 2912.1 and 1701.5 cm-1). The mixingratio vertical profiles of H2CO obtained during the SPIRALE flights are presented and compared. The HClmeasurements presented are the first to be made in situ in the lower and mid-stratosphere. In the tropicaltransition layer, they have been combined with recent very short-lived species (VSLS) ones in order toestimate the contribution of these compounds to the chlorine budget of the stratosphere. In the midstratosphere,the signatures present on the vertical profiles of HCl and ozone acquired simultaneously arestudied in connection with the quasi-biennal oscillation

Nous avons développé un détecteur intégré à base d'une diode pour être embarqué dans un ballon stratosphérique afin de caractériser l'environnement radiatif atmosphérique. Le détecteur a été calibré avec une source Californium, et il a été pleinement caractérisé lors de tests sous faisceaux de neutrons qui produisent diverses particules ionisantes secondaires. Les sections efficaces différentielles de détection pour différentes énergies de faisceaux de neutrons sont avérées être en bon accord avec les simulations effectuées avec le code MC-Oracle. Nous avons effectué un certain nombre de vols en ballon stratosphériques (avec l'ESA et le CNES) et confirmé la corrélation entre le taux de comptage et de l'altitude. En outre, nous avons observé que l'environnement radiatif n'est pas isotrope et démontré le potentiel de notre outil pour étudier l'environnement radiatif atmosphérique. Ces résultats sont utiles pour estimer le flux de particules qui affecte appareils et systèmes électroniques à bord des appareilsWe developed an integrated silicon detector to be embedded in a stratospheric balloon in order to investigate the radiative atmospheric environment. The detector was calibrated with a Californium source, and it was fully characterized under neutron beams which produced various secondary ionizing particles. Differential detection cross sections for different neutron beam energies were shown to be in good agreement with simulations performed with the MC-Oracle code. We performed four stratospheric balloon flights (with ESA and CNES) and confirmed the correlation between the count rate and the altitude. Moreover, we observed that the radiative environment is not isotropic and demonstrated the potential of our tool for investigating the radiative atmospheric environment. These results are useful for estimating the particle flux that affects electronic devices and onboard aircraft systems

Qi, Z. "Flushing ballast tanks." Thesis, University College London (University of London), 2015. http://discovery.ucl.ac.uk/1466478/.
Full textAbstract:
The non-indigenous species (NIS) transported by ships’ ballast water lead to destructive failure of the main ecologies giving rise to economic implications of many countries dependent on aquatic organisms. The International Maritime Organisation currently requires that ballast tanks are flushed three times with far ocean water. New protocols for cleaning technologies are still in discussion internationally. Current lacking is the science to understand how ballast tanks geometry and ballast water composition affect the NIS removal rate. This thesis describes a major contribution to this effort and identifies key engineering principles that should be taken into account to improve flushing efficiency. A combined experimental and theoretical study of flushing from ballast tanks is described. A hierarchy of laboratory scale models are designed, built and tested to understand the effect of geometry and stratification, with complexity increasing from 1×7, 2×2, 3×3 to 5×4 configurations. The experimental study is based on an optical method of interrogating the fraction of each compartment and whole tank that is cleaned. By drawing on modelling approaches applied in related areas, notably building engineering, a number of new mathematical models are developed that have no free variables (when resistance of pathways is the same) or require the use of closures for pressure drop coefficients. For homogeneous flow where stratification is negligible, the agreement between predictions and experiments is within 1.2%. Likewise, when resistances are different, the model is accurate, except when the inhomogeneity is significant. Three models are developed to include the influence of stratification. For miscible fluids, the stratified mixing model is accurate within 5% at Richardson number between 30 and 1000. We apply the validated models to examine how to change practical ballast tanks and how cleaning efficiency affects the total NIS removal. To enhance flushing, a single outlet should be placed far from the inlet.

Full textAbstract:
A ballot theorem is a theorem that yields information about the conditional probability that a random walk stays above its mean, given its value St after some specified amount of time t. In the first part of this thesis, ballot theorems are proved for all walks whose steps consist of independent, identically distributed random variables that are in the range of attraction of the normal distribution. With a mild assumption on the moments of the steps, the results are strengthened; the latter results are shown to be within a constant factor of optimal when the value of the random walk at time t is of order t . Farther results are proved for random walks whose value after time t is of order O(t).In the second part of the thesis, two questions about the heights of random trees are studied. The random trees that are studied are of interest from both a purely probabilistic, and an algorithmic perspective. It turns out that in two seemingly very distinct settings, the height of a random tree turns out to be closely linked to the behavior of a random walk, in particular to the probability that a random walk stays above its mean. The tools developed in the first part of the thesis, together with additional results, are then used to derive information about the moments of the height of these random trees. We also demonstrate that this information can be used to bound the moments of the minima of certain branching random walks.

Full textAbstract:
Voting is a fundamental decision making instrument in any consensus-based society. It is employed in various applications from student body elections, reality television shows, shareholder meetings, to national elections. With the motivation of better eciency, scalability, speed, and lower cost, voting is currently shifting from paper-based to the use of electronic medium. This is while aiming to achieve better security, such that voting result reflects true opinions of the voters. Our research focuses on the study of cryptographic voting protocols accommodating a flexible ballot structure as a foundation for building a secure electronic voting system with acceptable voting results. In particular, we search for a solution suitable for the preferential voting system employed in the Australian Federal Election. The outcomes of the research include: improvements and applications of batch proof and verication theorems and techniques, a proposed alternative homomorphic encryption based voting scheme, a proposed Extended Binary Mixing Gate (EBMG) mix-network scheme, a new threshold randomisation technique to achieve receipt-freeness property in voting, and the application of cryptographic voting protocol for preferential voting. The threats and corresponding requirements for a secure secret-ballot voting scheme are rst discussed. There are significant security concerns about the conduct of electronic voting, and it is essential that the voting results re ect the true opinions of the voters - especially in political elections. We examine and extend batch processing proofs and verifications theorems and proposed applications of the theorems useful for voting. Many instances of similar operations can be processed in a single instance using a batch technique based on one of the batch theorems. As the proofs and verications provide formal assurances that the voting process is secure, batch processing offers great efficiency improvements while retaining the security required in a real-world implementation of the protocol. The two main approaches in cryptographic voting protocols, homomorphic encryption based voting and mix-network based voting, are both studied in this research. An alternative homomorphic voting scheme using multiplicative homomorphism property, and a number of novel mix-network schemes are proposed. It is shown that compared to the mix-network approach, homomorphic encryption schemes are not scalable for straight-forward adaptation of preferential systems. One important requirement of secret-ballot voting is receipt-freeness. A randomisation technique to achieve receipt-freeness in voting is examined and applied in an ecient and practical voting scheme employing an optimistic mix-network. A more general technique using threshold randomisation is also proposed. Combination of the primitives, both the homomorphic encryption and mixnetwork approach, yields a hybrid approach producing a secure and ecient secret-ballot voting scheme accommodating a exible ballot structure. The resulting solution oers a promising foundation for secure and practical secret-ballot electronic voting accommodating any type of counting system.

Wortman, Leslie. "Savage Ballet." Digital Archive @ GSU, 2005. http://digitalarchive.gsu.edu/english_theses/4.
Full textAbstract:
The title Savage Ballet came into being because, so far as I articulate, it aptly describes the beauty and horror that are borne from combining art and instruction. Poetry, itself, is a ballet. And poetry, itself, is savage. It is a ballet of words carefully choreographed and practiced and spun into being. Poetry is the body politic of the ballet. It is beautiful and often fancy when the curtain rises, but behind the scenes and tucked into toe shoes is the instruction – the gnashing of teeth and blisters and broken nails. Thus, the savage side of poetry presents itself. And, may it also be said, graduate school is a savage beast. It wrestles and tests and knocks down to build up. And, if the dancer is lucky, they will rise.

Full textAbstract:
This dissertation explores intercultural theory through an investigation of butoh methods that shift performance processes of ballet. Theories of Post colonialism and Performance have been interrogated and applied to distill a theme, Butoh-Ballet. A qualitative research approach was undertaken for this study following a short series of dance workshops in butoh carried out on four members of Cape Town City Ballet company, in Cape Town, in 2013. This dissertation will show how butoh could contribute to overcoming colonial constructs, which have penetrated all spheres of South African society including Dance and its discourse. Dance research is fairly new in South Africa and largely situated within Contemporary dance. Ballet in South Africa has received relatively less critical analysis. The dissertation is particularly focused on expanding worldviews beyond a Eurocentric bias. Feminist notions as explicated by Ketu Katrak and Rustom Bharucha are considered in parallel to the philosophies of Maurice Merleau-Ponty. I also borrowed from Gayatri Spivak's notion of 'decolonising the imagination', to suggest that butoh may provide a means for ballet to re-imagine the body and its performance. This study acknowledges my subjective, 'endarkened' voice that emanates from my hybrid identity as Coloured, woman, pioneer Butoh artist, in postapartheid South Africa. I have proposed that butoh balances an external focus of the body found in ballet, with a more spiritually nuanced approach found in butoh. My argument hopefully marks the earliest reflective analysis of the subtle shifts butoh could make to ballet in South Africa today.

Full textAbstract:
In this thesis I will describe the methods used and problems I have faced and attempted to solve during my time developing a math game for younger kids, a game that makes an attempt to teach kids something called number sense. Teaching pre school kids about number sense is something relatively new and the group I have been working with are of the understanding that it’s something that is very likely to be important to prevent children from falling behind in math during the earlier years of school. Number sense basically means the ability to connect symbolic numbers to their meaning interms of sets, amounts and dimensions such as larger-smaller, higher-shorter, more-less, etc. If this proves to be useful then the quality of education will improve as a result of more children being able to keep up with their math from an early stage.

Lo scopo di questa tesi è quello di analizzare a fondo il concetto sovrastruttura ferroviaria senza ballast e sottolinearne pregi e difetti rispetto a quella tradizionale con pietrisco, al fine di identificare chiaramente quando e dove i sistemi senza massicciata forniscono prestazioni migliori. L'aumento dei costi di manutenzione delle sovrastrutture ferroviarie al giorno d'oggi stanno aprendo la strada a nuovi sistemi, la maggior parte sviluppati in paesi che hanno linee di velocità elevate e tanti altri paesi si stanno preparando per aggiornare le proprie linee esistenti, nonché per creare nuove linee ferroviarie ad alta velocità. In molti casi i sistemi senza ballast sembrano avere le potenzialità per offrire un servizio per linee ad alta velocità più efficiente rispetto alle tracce tradizionali con ballast, soprattutto a causa della loro maggiore stabilità strutturale, del basso bisogno di manutenzione e del lungo ciclo di vita. Il primo capitolo è dedicato alla descrizione della struttura del binario tradizionale con ballast analizzando gli strati che formano la sovrastruttura.
Il secondo capitolo è dedicato alla descrizione di varie tipologie, utilizzate nel mondo, di sovrastrutture ferroviarie senza ballast, di ognuna di esse sono state elencate le caratteristiche costruttive e prestazionali.
Il terzo capitolo è dedicato al confronto tra le due tipologie di sovrastruttura, sono state descritte le capacità elastiche e deformative delle due soluzioni, il degrado cui incorrono le due soluzioni, gli stati sollecitanti a cui sono sottoposte e la risposta delle stesse. Di particolare importanza è il confronto di costo dei due sistemi e il rumore e le vibrazioni generate da questi; infatti negli ultimi anni questi sono gli aspetti fondamentali su cui si basa la scelta di un sistema costruttivo; a seguito di questo confronto è stato possibile trarre le conclusioni.

Full textAbstract:
Astronomy constantly pushes the limits of technology in order to decipher the workings of the Universe. There is a constant need for higher resolution observations across a wide range of wavelengths, at preferably a minimal cost. The terahertz regime (lambda=100 um to lambda=1000 um) covers a region of the electromagnetic spectrum that is blocked by Earth's atmosphere, which limits observations to high altitude plane and balloon telescopes and space telescopes. These current options limit the resolution achievable due to the size of telescopes that can be launched. This dissertation investigates a new approach, the Large Balloon Reflector (LBR), where a 20 meter diameter spherical balloon can be inflated and used as a 10 meter telescope inside a larger carrier balloon. Detailed in this dissertation are design considerations for the terahertz regime and a series of scaled versions of this balloon concept where I work to develop on-axis spherical corrector designs. Chapters 1 through 6 focus on the LBR designs and their variants, including investigations for a 3 meter rooftop proof of concept model, a 5 meter test flight model, and the final 20 meter LBR. The successful modeling and proof of concepts from the LBR studies then prompted an investigation into a Terahertz Space Telescope (TST), a proposed 20 meter inflatable telescope adapted from the LBR technology. Starting with Chapter7, this dissertation explores the application of using 1 meter diameter inflatable balloons as rapidly deployable communications satellites from standard CubeSats. The concept, design and test results of an electronically steerable line feed antenna array are presented which allows for instantaneous, non mechanical pointing of a 10 GHz signal within a 500 km ground footprint. Alternative uses of the 1 meter inflatable balloon CubeSat are also discussed, such as low cost astronomical galactic plane surveys.

Full textAbstract:
It is important to have consistent ballast testing methods that provide results reflecting the performance of different ballast materials in the railway trackbed. In this research, extensive laboratory tests were conducted to investigate the correlation between simple ballast index tests, and box tests simulating ballast field loading conditions in a simplified and controlled manner. In the box test, a sleeper load of 40kN was applied to a simulated sleeper on the top of a sample of ballast in a box of dimensions 700x300x450mm. The ballast was tamped using a Kango hammer which caused particles to rearrange as the level of the sleeper was raised. The ballast tests investigated in this project are those ballast tests specified in the Railtrack Line Specification (RT/CE/S/006 Issue 3, 2000), in addition to single particle crushing tests, oedometer tests, petrographic analysis, and box tests. It was found that there was some correlation between the single particle crushing tests, oedometer tests, box tests and petrographic analysis. One of the current ballast tests, namely the Aggregate Crushing Value (ACV) test, which is analogous to the oedometer test, is not appropriate because the ACV test uses 10-14mm ballast particles, and there is a size effect on the strength of ballast and different ballasts have different size effects. However, if an oedometer test is used on track ballast, the results correlate better with ballast field performance as simulated in the box tests. Six ballasts were tested: A, B, C, D, E and F (mineralogy of these ballasts can be found in the appendix). The aim was to examine the relative performance of these ballasts and to establish which index tests were most indicative of performance in the box test. Simple index tests were performed on each of the ballasts, whilst box tests were only performed on ballasts A, B, C and D. The box tests were generally performed wet by adding a known volume of water at each tamp. For ballast A, controlled tests were also performed on dry ballast, and tests involving traffic loading only and tamping only were also conducted. A box test on 10-14mm ballast A was also conducted to investigate the size effect on ballast behaviour in the box. The Wet Attrition Value (WAV), Los Angeles Abrasion (LAA), and Micro-Deval Attrition (MDA) seem to be suitable parameters to indicate ballast performance in the box test. However, this is considered to be due to the rearrangement of particles in the box test caused by the simulated tamping. In addition to the laboratory tests, the application of discrete element program PFC3D (Itasca Consulting Group, Inc., 1999) in simulating ballast behaviour was also investigated. Single particle crushing test was simulated to produce crushable agglomerates with a distribution of strengths of ballast A. These agglomerates were then used to simulate the oedometer test. The resulting normal compression line was compared with that for real oedometer tests: discrepancies can be attributed to the simplified geometry of the agglomerates. Due to the high computational time in simulating a box test with crushable agglomerates, uncrushable spherical balls and uncrushable angular agglomerates were used to represent individual ballast particles in the box. Important aspects of ballast behaviour under repeated loading, namely resilient and permanent deformation, were studied. It was found that the box test on uncrushable angular agglomerates give less permanent deformation compared with the test on spherical balls, because of the additional resistance provided by the irregular shape of the agglomerates.

This research validates electro-disinfection as a potential secondary ballast water treatment technology. Electricity applied to bacteria laden water produced bactericidal effects, reactive oxygen species and chlorine generation which annihilated bacteria. Evaluation of electro-disinfection experiments showed titanium electrodes had the maximum kill efficacy while disinfection with aluminum and stainless steel electrodes had lesser kill efficacy. A continuous flow electro-disinfection reactor was evaluated utilizing artificial brackish and fresh ballast water. Brackish water had a 100% bacteria kill efficiency utilizing titanium electrodes at a current density of 10 mA/cm2. Fresh water was augmented with the addition of salt to increase its electrical conductivity from 232 μS/cm to 873 μS/cm to ascertain 100% bacteria kill efficiency with titanium electrodes and a current density of 9.8 mA/cm2.

Android balloon game application is an android application which helps in improving the children’s vocabulary power. This application provides a graphical user interface with words as questions and balloons as the options. The end user will have to select a balloon in order to select an answer. There are three modules in this application which are game mode, new game and high scores. In the basic module questions like Alpha_bet are included. Also as an enhancement, the game is made interesting by giving the user three lives to clear the levels of the game. Three small balloons are included in the application which resemble the three lives and once an incorrect answer is selected, the green balloon will be replaced by a red balloon depicting an incorrect answer. Also the scores will be computed for every correct option that is selected by the user. The score is incremented by ten points for every correct answer. And for the high score section, the game would maintain the list of top players. High score section will consist of the user’s name, score, time and date for the gameplay. Apart from that a next button is included which helps the user to skip a word which the user finds it difficult to answer. A hint option is also provided in the game which pronounces the word helping the user to guess the word correctly.

Full textAbstract:
Dans un contexte actuel préoccupé par la couche d’ozone et son recouvrement ainsi que par le réchauffement global, comprendre, représenter et modéliser la dynamique stratosphérique sont des enjeux majeurs. Une question récurrente est de pouvoir évaluer les biais des modèles à haute altitude dans la stratosphère. Or la stratosphère est une couche de l’atmosphère difficilement accessible à la mesure. Une solution est d’extraire des informations en analysant les trajectoires des ballons qui sont essentiellement conditionnées par les mouvements des masses d’air. Ces travaux de thèse ont donné naissance à une banque de données rassemblant des mesures de vent, de température et de pression issues des vols de ballons stratosphériques sur une période de plus de 20 ans à des régions variées (région polaire arctique, à moyenne latitude et en régions intertropicales) et à différentes saisons. Une méthode d’analyse des biais mesures/modèle a été mise en place et appliquée aux réanalyses ERA-Interim. Par comparaison avec une précédente étude faite dans des conditions de vortex polaire, les mesures ainsi que la méthode d’analyse des biais ont été validées. Enfin, une analyse systématique des biais sur le vent à haute altitude dans la stratosphère considérant plusieurs régions à différentes saisons a été implémentée. Les résultats montrent que les biais dans les réanalyses ERA-Interim varient et augmentent en fonction de l’altitude. Les régions associées à des régimes bien établis sont plutôt bien représentées alors que les zones de transition ou de changement de circulation présentent plus de difficultés. D’une manière générale, les résultats de biais rapportent que les réanalyses ERA-Interim sous-estiment la vitesse du vent dans la stratosphèreIn a current context focused on the ozone layer recovery and on the global warming, understand, represent and model the stratospheric dynamic became major issues. Realism of these models needs to be assessed. Unfortunately the stratosphere is an atmospheric layer hardly accessible to measurements. Balloons trajectories are mainly depending on the air masses displacements. Extract measurements from balloon trajectories is a solution. These works led to the creation of a database which contains winds, temperature and pressure measurements from stratospheric balloons flights data collected over a time period of more 20 years at several locations (arctic polar region, at mid-latitude and in tropics) and at different seasons. A methodology of winds biases analysis has been developed and has been applied to the ERA-Interim reanalysis data. By comparing our results with a previous study, we have been able to validate the database and the winds biases analyse methodology. A systematic analyse of winds biases at high altitude in the stratosphere considering several locations/seasons has been implemented. The results show the biases in ERA-Interim reanalyses vary and rise as function of the altitude. The locations which are associated to well established circulations are rather well represented while the locations where the variability is higher present more difficulty. Globally biases results report ERA-Interim reanalyses underestimate wind speed in the stratosphere

Full textAbstract:
INTRODUCTION: The prevalence of ACL injuries is increasing in previous years. One of the most common studied kinematic risk factors related to ACL injuries is a resultant weak, leg axis alignment known as the dynamic knee valgus angle presented during a vertical drop jump [8, 14, 15]. Hewett et. al. concluded that a knee valgus angle was a primary predictor of the mechanism that leads to an ACL rupture [8]. By increasing the excessive knee valgus angle during a two-legged DVJ, an athlete is in turn increasing the possibility of a high knee valgus moment, which can increase the anterior tibial translation as well as the load on the ACL several-fold and the chances for an ACL tear [4].
METHODS: In our study, ten collegiate female participants, including ballet and non-ballet athletes performed two-legged DVJs for 6 different flexor and extensor muscles while digital recordings of knee valgus angle were captured at initial contact and push off with simultaneous collection of EMG data.
RESULTS: Results displayed statistical significance for the average valgus angle to estimated GRF ratio for the non-dominant leg at push-off between the ballet and non-ballet athletes (0.8 ± 0.43 vs. 1.8 ± 0.33 degrees/N, p < 0.05). In addition, we also found that the hip extensor activity significantly increased for the non-ballet group and that the lateral thigh CCI noticeably increased for the non-dominant leg for the non-ballet group, which could be indicative of the noticeable difference in the biceps femoris muscle activation for the non-ballet group when comparing sports type. In addition, statistically significant interactions between sports type and leg type for vastus medialis and gluteus maximus were produced. Observed results also indicated that there was an increase in overall variability for the dominant leg of the non-ballet athletes amongst all studied muscles and for the non-dominant leg for the ballet group specifically studying the gluteus maximus muscle activity.
DISCUSSION: Relatively, the non-ballet group could be at a higher risk for increase in femoral adduction, hip adduction, and tibial external rotation, and overall predict a larger knee valgus moment; therefore, the non-ballet group could potentially be at a higher risk for an ACL injury than the ballet group. In addition, there is potential in continued research of neuromuscular differences between ballet and non-ballet athletes to further investigate the vastus medialis and the gluteus maximus muscle activations as well as to investigate the knee valgus moment values.

Full textAbstract:
This thesis work comprises the working and simulation procedures being involved in simulating motion capture data in AnyBody Modeling System. The motion capture data used in this thesis are ballet movements from dancers of Östgöta ballet and dance academy. The ballet movements taken into consideration are the arabesque on demi-pointe and pirouette. The arabesque on demi-pointe was performed by two dancers but the pirouette is performed by only one dancer. The method involved recording ballet movements by placing markers on the dancer's body and using this motion capture data as input to AnyBody Modeling System to create a musculoskeletal simulation. The musculoskeletal modeling involved creating a very own Qualisys marker protocol for the markers placed on the ballet dancers. Then implementing the marker protocol onto a human model in AnyBody Modeling System by making use of the AnyBody Managed Modeling Repository (TM) and obtain the kinematics from the motion capture. To best fit the human model to the dancer's anthropometry, scaling of the human model is done, environmental conditions such as the force plates are provided. An optimization algorithm is conducted for the marker positions to best fit the dancer's anthropometry by running parameter identification. From the kinematics of the motion capture data, we simulate the inverse dynamics in AnyBody Modeling System. The simulations explain a lot of parameters that describe the ballet dancers. Results such as the center of mass, the center of pressure, muscle activation, topple angle are presented and discussed. Moreover, we compare the models of the dancers and draw conclusions about body balance, effort level, and muscles activated during the ballet movements.

Full textAbstract:
What explains the outcomes of ballot initiative contests? What factors determine the passage or rejection of an initiative? This paper describes and evaluates three approaches to explaining ballot initiative contest outcomes. The first approach involves using the expenditures of Yes and No campaigns as the causal factor in explaining why passage or defeat is the respective outcome of a given contest. The second explanatory approach emphasizes the logic of collective action problems. The third approach incorporates the larger constellation of policymaking institutions in which each ballot initiative process exists. Specifically, in what ways is the process shaped by the larger system of partisan attachments that structures electoral politics?
This paper contains a set of three analyses which speak to each of the three respective explanatory approaches to explaining initiative contest outcomes. The results provide evidence of the importance of a contest's early competitive dynamic in determining the amount of resources made available for a campaign to spend. Left unaccounted for, this strategic financing of initiatives distorts estimates of the effectiveness of spending.
The second analysis, inspired by insights into collective action problems, finds the initiative arena to be a policymaking site where there is a competitive advantage for broadly diffused interests, especially when they challenge other broad interests. Moreover, broad-based Yes groups achieved relatively high passage rates with relatively low levels of campaigns expenditures.
Finally, the third analysis provides evidence of a consistently high level of correlation between Yes voting and alignment with a particular party. The lowest levels of correlation were still fairly high from a measured social science perspective. In many instances, county-level party attachment mapped almost seamlessly over initiative decision making. This suggests that ballot initiatives politics do not operate outside party politics, as has been suggested in the past.

Full textAbstract:
The super Catalan numbers T(m,n) = (2m)!(2n)!=2m!n!(m+n)! are integers which generalize the Catalan numbers. Since 1874, when Eugene Catalan discovered these numbers, many mathematicians have tried to find their combinatorial interpretation. This dissertation is dedicated to this open problem. In Chapter 1 we review known results on T (m,n) and their q-analog polynomials. In Chapter 2 we give a weighted interpretation for T(m,n) in terms of 2-Motzkin paths of length m+n2 and a reformulation of this interpretation in terms of Dyck paths. We then convert our weighted interpretation into a conventional combinatorial interpretation for m = 1,2. At the beginning of Chapter 2, we prove our weighted interpretation for T(m,n) by induction. In the final section of Chapter 2 we present a constructive combinatorial proof of this result based on rooted plane trees. In Chapter 3 we introduce two q-analog super Catalan numbers. We also define the q-Ballot number and provide its combinatorial interpretation. Using our q-Ballot number, we give an identity for one of the q-analog super Catalan numbers and use it to interpret a q-analog super Catalan number in the case m= 2. In Chapter 4 we review problems left open and discuss their difficulties. This includes the unimodality of some of the q-analog polynomials and the conventional combinatorial interpretation of the super Catalan numbers and their q-analogs for higher values of m.

Full textAbstract:
Discrete element modelling has been used to capture the essential mechanical features of railway ballast and gain a better understanding of the mechanical behaviour and mechanisms of degradation under monotonic and cyclic loading. A simple procedure has been developed to generate clumps which resemble real ballast particles. The influence of clump shape on the heterogeneous stresses within an aggregate was investigated in box test simulations. More angular clumps lead to greater homogeneity and the interlocking provides a much more realistic load-deformation response. A simple two-ball clump was used with two additional small balls (asperities) bonded at the surface, to represent a single particle; it is shown that particle abrasion gives the correct settlement response. A clump formed from ten balls in a tetrahedral shape was used in monotonic and cyclic triaxial test simulations and found to produce the correct response. The interlocking and breaking of very small asperities which find their way into the voids and carry no load was modelled using weak parallel bonds. The interlocking and fracture of larger asperities was modelled by bonding eight small balls to the ten-ball clump. Monotonic tests were performed on triaxial samples under different confining pressures and the results compared with existing experimental data. Tests were also simulated using uncrushable clumps to highlight the important role of asperity abrasion. Cyclic triaxial tests were then simulated on the same aggregates under a range of stress conditions and the results compared to existing experimental data for the same simulated ballast. The clumps are able to capture the behaviour of ballast under different conditions, and asperity abrasion plays an important role in governing strength and volumetric strain under monotonic loading, and on permanent strains under cyclic loading. The contribution of this thesis is therefore to show that it is possible to model a real granular material under static and cyclic conditions, providing much micro mechanical insight.

International Telemetering Conference Proceedings / October 26-29, 1992 / Town and Country Hotel and Convention Center, San Diego, CaliforniaA new antenna design, which is particularly suited for balloon telemetry applications, is presented. In the past, simple monopoles have been utilized as transmit antennas on balloon payloads. The monopole radiation pattern has an inherent null along its axis. This causes an undesirable loss of signal when the balloon is directly overhead. To prevent this occurrence, a microstrip antenna patch was incorporated into the monopole design. This combination, a "monopatch" antenna, provides sufficient coverage even when the balloon is directly over the ground station. The monopatch has been successfully flown on high altitude balloon flights.

Full textAbstract:
The performance of a railway track structure is significantly influenced by ballast shape properties such as roundness, flatness, elongation, sphericity, angularity and surface texture. Railway ballast materials have to comply with several quality requirements and shape properties. Accurate measurement of the shape properties is important for developing and revising specifications for quality control and quality assurance in the selection of ballast materials for railway construction. However, the current test methods for determining these properties have severe shortcomings such as poor repeatability and subjectivity. In addition, they are often based on visual measurements and empirically developed charts, which lack scientific standing. In this study, an advanced three-dimensional (3D) laser scanning was used to quantify the shapes of railway ballast materials from a heavy haul coal line in South Africa. This study complements the current research by the Council for Scientific and Industrial Research (CSIR) that is aimed at introducing advancement and scientific approach (i.e. 3D-laser scanning and numerical techniques) to effectively model the shape of crushed stones i.e. aggregates for roads and ballast for railways used in transport infrastructure. The primary objective was to investigate the effect of ballast particle shape, determined from a modern 3D-laser scanning technique, on the performance characteristics (i.e. shear strength and permanent deformation) of ballast materials. Overall, five ballast materials (four recycled ballast materials from the coal line and one freshly crushed ballast) and one river aggregate were investigated for this study. All six materials were scanned in the 3D-laser scanning system and the data were processed to reconstruct three dimensional models of the ballast and the river pebble particles. The models were further analysed to determine the roundness, flatness, elongation, and sphericity shape properties of the particles. The results obtained were used to develop different charts to characterise ballast shapes. An ANOVA (Analysis of variance) statistical analysis was conducted on the three dimensional data to establish which individual ballast particles contributed significantly to the overall shape parameters. To evaluate the effects of the shape properties on the behaviour of ballast in the track structure, a laboratory testing programme was conducted to determine the settlement behaviour and shear strength of the ballast materials. Repeated load permanent deformation tests were conducted to evaluate the overall settlement behaviour, whereas monotonic static triaxial tests were used to determine the shear strength properties of the ballast materials. The results indicated that ballast materials with low roundness values exhibited low shear strength and high permanent deformation (settlement). Although this was expected, the use of the automated 3D-laser scanning approach introduced a high level of accuracy and confidence in the results. Based on the laser results, a new empirical model was developed to determine the surface area of the ballast materials. The surface area values were further used to develop a chart to assess different particle shapes with varying degrees of roundness. Triaxial tests were conducted to determine the effect of the roundness on the shear strength properties of the materials. A Mohr-Coulomb failure model was successfully developed from the results to represent the individual materials tested. The overall results show that the angle of internal friction decreases with an increase in the roundness index of the particles. More rounded particles have roundness index values of between 1.4 and 1.7 whereas less rounded particles have roundness index values of between 0.8 and 1.3. The outcomes of this study would assist with quality control in the field as to whether or not to replace degraded ballast in the track layer. It is anticipated that this study will enhance improved guidelines, test methods and specifications for the selection of ballastDissertation (MEng)--University of Pretoria, 2017.

Full textAbstract:
Do the physical settings in which a voter casts their ballot affect their vote choices? Every state uses a variety of polling locations for the administration of election: churches, schools, libraries, fire stations, and etcetera. The literature on priming effects and voting is massive, but very little research examines the impact of the venue in which a ballot is cast has on voters’ decisions. In this study I argue that polling venues situated on church, school, or veteran’s association property influences the proportion of votes cast in favor of ballot measures related to each institution. I test these hypotheses using precinct level election results and population data from California’s 2008 general election and find results supporting, or suggesting, such a relationship.

Full textAbstract:
Elections---often to a considerable degree---influence the fiscal policies pursued by governments installed on the basis of their results. Nonetheless, government behaviour is typically modelled exogenously, usually by means of a benevolent, permanently installed "social planner." However, since fiscal policies, devised by democratically elected governments, complement the decentralised pricing system, which---as shown by Samuelson (1954)---is incapable of optimally allocating both private and public goods, the social-planner approach is viewed as being an unsatisfactory tool for the purpose of describing the political aspects of economic decisions.In the absence of a "first-best," Pareto-optimal tax system, fiscal policies are implemented as a result of inter-household "conflicts" over tax rates and public spending. In order to be able to overcome the theoretical difficulties encountered in previous contributions to the Economic Theory of Politics, this text will propose a model that explicitly depicts---"democratically aggregated"---political decisions made on the level of every individual.
In this thesis, it will be shown that (i) a country's overall budget can be derived endogenously without relying on the theoretical shortcut of interpersonal preference aggregation, (ii) electoral fluctuations be explained on the basis of the changes to the individuals' particular income and wealth situations, (iii) political behaviour be described in terms of votes and abstentions as well as party membership and ideology, and (iv) the crucial importance of a country's wealth distribution be discussed in the context of economic stability and the role of government.

Includes bibliographical references (p. [219]-244).
The objective of this dissertation is to systematize the existing hypotheses in the electoral engineering literature and to test them in a set of selected case studies in order to answer a central question: does the electoral system affect the structure of political parties in ethnically divided societies and if so how? The academic debate on electoral design for divided societies has focused on the impact of institutional choices on ultimate conflict outcomes. The findings of previous studies have been generally inconclusive, while the lack of sub-national data on ethnic composition and voting patterns has made it difficult to examine mechanisms regarding the role of demographics. To approach the problem from a different angle, I propose a research design focusing on the intermediate link from electoral institutions to the ethnic structure of the party system. For the empirical portion of my work, I chose to conduct a structured historical comparison of four societies which implemented major electoral reforms: Turkey, Northern Ireland, Guyana, and Sri Lanka. Based on the study of these cases, I am arguing that politicians and voters have not responded to electoral incentives in the ways predicted by existent theories, and that no clear relationship can be observed between the electoral system's proportionality, the heterogeneity of electoral constituencies, and the number of parties or the types of ethnic appeals they make to voters. These findings indicate that the hopes placed in electoral system design for divided societies are unwarranted and that attention among political scientists and policymakers should shift to other peace-building approaches.

Full textAbstract:
Since the Help America Vote Act (HAVA) in 2002 that addressed improvements to voting systems and voter access through the use of electronic technologies, electronic voting systems have improved in U.S. elections. However, voters with disabilities have been disappointed and frustrated, because they have not been able to vote privately and independently (Runyan, 2007). Voting accessibility for individuals with disabilities has generally been accomplished through specialized designs, providing the addition of alternative inputs (e.g., headphones with tactile keypad for audio output, sip-and-puff) and outputs (e.g., audio output) to existing hardware and/or software architecture. However, while the add-on features may technically be accessible, they are often complex and difficult for poll workers to set up and require more time for targeted voters with disabilities to use compared to the direct touch that enable voters without disabilities to select any candidate in a particular contest at any time.
To address the complexities and inequities with the accessible alternatives, a universal design (UD) approach was used to design two experimental ballot interfaces, namely EZ Ballot and QUICK Ballot, that seamlessly integrate accessible features (e.g., audio output) based on the goal of designing one voting system for all. EZ Ballot presents information linearly (i.e., one candidate’s name at a time) and voters can choose Yes or No inputs that does not require search (i.e., finding a particular name). QUICK Ballot presents multiple names that allow users to choose a name using direct-touch or gesture-touch interactions (e.g., the drag and lift gesture). Despite the same goal of providing one type of voting system for all voters, each ballot has a unique selection and navigation process designed to facilitate access and participation in voting.
Thus, my proposed research plan was to examine the effectiveness of the two UD ballots primarily with respect to their different ballot structures in facilitating voting performance and satisfaction for people with a range of visual abilities including those with blindness or vision loss. The findings from this work show that voters with a range of visual abilities were able to use both ballots independently. However, as expected, the voter performance and preferences of each ballot interface differed by voters through the range of visual abilities. While non-sighted voters made fewer errors on the linear ballot (EZ Ballot), partially-sighted and sighted voters completed the random access ballot (QUICK Ballot) in less time. In addition, a higher percentage of non-sighted participants preferred the linear ballot, and a higher percentage of sighted participants preferred the random ballot.
The main contributions of this work are in: 1) utilizing UD principles to design ballot interfaces that can be differentially usable by voters with a range of abilities; 2) demonstrating the feasibility of two UD ballot interfaces by voters with a range of visual abilities; 3) providing an impact for people with a range of visual abilities on other applications. The study suggests that the two ballots, both designed according to UD principles but with different weighting of principles, can be differentially usable by individuals with a range of visual abilities. This approach clearly distinguishes this work from previous efforts, which have focused on developing one UD solution for everyone because UD does not dictate a single solution for everyone (e.g., a one-size-fits-all approach), but rather supports flexibility in use that provide a new perspective into human-computer interaction (Stephanidis, 2001).

Full textAbstract:
Equilibrium is the name of a ballast-free oil tanker concept invented by naval architects at Det Norske Veritas (DNV) and further developed in this master’s thesis at the Norwegian University of Science and Technology (NTNU). The task is to analyze the conceptual design work done by DNV and further develop the concept. The main focus is on a cost comparison with a conventional tanker with a deadweight equal to Equilibrium and a conventional VLCC. The cost comparison focuses only on the costs that are expected to be different in these designs: Building costs, fuel costs and the cost of ballast equipment and operation. This comparison serves as an indicator of the profitability and thereby feasibility of the design. A trapezoid shaped hull and longitudinal cargo boundaries make Equilibrium independent of ballast in transit and during loading and discharging. The ballast-free return legs result in a significant annual saving of fuel and CO2 emissions. This is Equilibrium’s main advantage over a conventional design. Equilibrium’s main disadvantage is that the cargo capacity is about 60 000 tons lower than on a conventional VLCC. This again affects the cost efficiency of the ship. Since Equilibrium is bigger than the Suezmax limitations, the VLCC is regarded as the main competitor. A cost-efficiency index of the relevant life cycle costs over 10 years divided by the amount of cargo delivered in the same period, shows that Equilibrium is a profitable design. Further analyses needs to be done on the ship’s sea keeping abilities with special attention to accelerations in roll motion. The proposed Equilibrium design can compete against existing tankers on both cost-benefit and environmental impact.

Full textAbstract:
In the span of two decades, Hizballah has evolved from an armed resistance movement against Israeli occupation into an efficient political party and---by extension---into a permanent fixture on Lebanon's mainstream political stage. The present analysis traces the evolution of the party from its inception and assesses its performance vis-a-vis the major players of Iran, Israel and Syria. Factors including the characteristics of the movement and the Shiite community itself, the shifting position, interests and policies of various regional actors, and the changing domestic conditions in Lebanon were isolated in order to adequately explain the behaviour and development of Hizballah. As a result, such alternatives to cultural factors (i.e the "Islamic variable") were found to be stronger explanatory factors rather than the Islamic factor. Ultimately, the essay illustrates that Islamic considerations are secondary, if not tertiary, when political decisions are to be made in different contexts. Rather, it is the interests of the more powerful actors that govern the organization's next move, in addition to the aforementioned variables. On the basis of such assumptions and findings, conclusions were finally drawn regarding Hizballah's future developments and its prospects following an Israeli withdrawal.

Full textAbstract:
The “green agenda” combined with highway congestion has accelerated the demand for increased freight and passenger travel on the world’s railways. These increases have driven demand for more efficient and rapid investigation of trackbed ballast. Network Rail and other rail infrastructure operators spend significant financial sums on inspecting, tamping, adjusting, cleaning, and replacing trackbed ballast. Such maintenance is often to the detriment of normal network operation. Industry requires a method of ballast evaluation that is non-intrusive, cheap, can appraise long stretches of track in a short period of time, and give a fingerprinting result from which time-to-maintenance can be calculated and planned. Thus, the aim was to develop evaluation methods using non-destructive testing techniques. A 10-year old full-scale trackbed composed of variously fouled ballast was re-visited and used for experimentation. The condition of the ballast was calculated using the Ionescu Fouling Index. Earlier research at the University of Edinburgh enabled researchers worldwide to characterise ballast using ground penetrating radar (GPR). This research was repeated, validated and taken forward in a series of GPR experiments on the trackbed using a range of antennas from 500MHz to 2.6GHz. New "scatter" metrics were developed to determine ballast condition from the GPR waveforms. These metrics were then used to predict the Ionescu Fouling Index with a correlation coefficient greater than 0.9. One of the current approaches to evaluating the stiffness of railway ballast is to use a Falling Weight Deflectometer (FWD). The viability of using a Prima 100 mini-FWD on railways to measure stiffness was determined and deemed to be ineffective on ballast. The applicability of the impulse response technique on railways was determined. An instrumented hammer was used to excite the ballast, with a geophone measuring the response. The Frequency Response Function of this was successfully correlated with the Ionescu Fouling Index with a correlation coefficient also greater than 0.9. Finally, using GPR data and measured stiffness data collected by Banverket, Sweden, a numerical model to successfully relate radar responses to stiffness was developed.

This work is a comprehensive investigation to find to what extent simple laboratory tests e.g. Los Angeles abrasion and micro-Deval might be suitable for predicting real railway ballast performance with respect to deformation and degradation. A number of tests to measure essential properties of ballast aggregate have been performed in addition to advanced material testing. Large cyclic triaxial loading test and full scale railway track model test were employed to simulate the effects of train loading and tamping, and to study settlement, stiffness and degradation of a range of ballast materials. The testing programme included both wet and dry testing conditions. All the rock types tested were mainly composed of combinations of principal rock-forming silicate minerals. They represent all together a wide variety of igneous, metamorphic and consolidated/metamorphosed sedimentary rocks mainly fine to very fine grained. Mechanical properties Change in the ballast grading proved to affect the ballast breakage development over time. However, the abrasion property expressed by the micro-Deval value did not show any association with the degradation of ballast under repeated load testing. Simulation of repeated tamping seemed to be the main source of ballast breakage. Most rocks showed high frost resistance after long term impact, but samples with high content of amphibole were less frost resistant. The rocks’ mechanical strength in terms of the Los Angeles abrasion or micro-Deval value did not show any correlation with either the amount of microcracks or the rocks’ average mineral grain size. A new method to measure the amount of microcracks based on luminescence measurements was developed. It is suggested that micro-cracks represent open channels for water to penetrate into the aggregate, which was confirmed by good correlation between water absorption and the amount of micro-cracks. Moisture had generally a negative effect on rocks’ mechanical strength according to Los Angeles abrasion and Point Load strength results. On the other hand, dry and wet triaxial tests with cyclic loadings did not confirm this effect. Neither did mineral grain size distribution show any correlation with mechanical strength, but the range of coefficient of conformity (Cu = D60/D10) was probably too narrow to obtain a reliable conclusion. A new method to quantify the mineral grain size distribution was developed under these test series. Functional properties Both resilient modulus of the ballast layer and the stiffness of the track were governed by the materials’ grading curve and specific density. A possible relation between the amount of microcracks in the aggregate and resilient modulus as well as ballast breakage is suggested. The permanent vertical strain during repeated load testing was affected by both the micro-Deval value, the grading curve of the ballast and the aggregate’s content of soft minerals. Improvements of test methods The Los Angeles abrasion test distinguished clearly between the superior quality material and the very poor material. The Los Angeles abrasion value is, however, a poor parameter to indicate how the intermediate material will behave in service regarding ballast breakage. This study proposes to improve the ranking of ballast materials by introducing two additional methods. One which is able to measure some rocks’ ability to recover mechanical strength after repeated crushing, and one which measures the production of fines (0/0.125 mm) during crushing. Saturation of ballast material before micro-Deval testing did not have any significant effect on degradation. Neither did the use of 1 % sodium-chloride solution have any effect.
