▼ 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. Advisors/Committee Members: Theron, Nicolaas J (advisor).

▼ Building abstract concepts is essential to humans when acquiring knowledge, realizing processing (reasoning), and communicating findings. Abstraction comes hand in hand with information granules and information granulation. When analyzing digital images, we form groups (clusters) of pixels, colors, and textures that constitute familiar objects. This paramount ability of forming groups of objects (information granules), manipulating them, and producing sound conclusions, is realized in an almost subconscious manner. Information granules are critical when representing and processing knowledge. They become instrumental when solving everyday problems. The objective of this dissertation is to design, analyze, and optimize granular fuzzy models in which information granules play a pivotal role. In the presented considerations, fuzzy models serve as a vehicle for the construction of granular fuzzy models, offering a convenient and efficient way to describe complex and nonlinear systems. Fuzzy models produce numeric results. In contrast, granular fuzzy models produce results in the form of information granules. In this study, we develop a novel approach to the design and optimization of fuzzy relational structures. Subsequently, we transform them into their granular counterpart by experimenting with different strategies to optimally allocate information granularity. This direct generalization (abstraction) of the fuzzy model comes as a sound alternative to solve a system of relational equations, and to assess the quality of the original model. Granular fuzzy models are also developed by exploiting a concept of information granularity. We propose an innovative model coming as a network of associations among information granules, which form the backbone of the overall construct. Interval information granules positioned in the output space induce information granules in the input space, and we develop different strategies to optimize these intervals. Further optimization of the model is proposed by optimally re-distributing the iii induced information granules. The performance of granular models is assessed by considering criteria of coverage and information specificity (information granularity). The associations are further exploited to construct a granular model that is fundamentally structured around information granules regarded as hyperboxes. We develop two novel methods to construct a family of hyperboxes in the input space; one by realizing some constrictions, and the other one by engaging an optimization mechanism. We also propose a new approach to optimally eliminate or reduce possible overlap among hyperboxes. The resulting information granules are compared and assessed in terms of their coverage, and the data captured by those is evaluated by proposing a three-step verification process. Furthermore, in this research we propose a novel approach to refine information granules produced by the Fuzzy C-Means algorithm, and optimize their representation and classification abilities. We develop different strategies to…

▼ Clustering algorithms are a primary tool in data analysis, facilitating the discovery of groups and structure in unlabeled data. They are used in a wide variety of industries and applications. Despite their ubiquity, clustering algorithms have a flaw: they take an unacceptable amount of time to run as the number of data objects increases. The need to compensate for this flaw has led to the development of a large number of techniques intended to accelerate their performance. This need grows greater every day, as collections of unlabeled data grow larger and larger. How does one increase the speed of a clustering algorithm as the number of data objects increases and at the same time preserve the quality of the results? This question was studied using the Fuzzy c-means clustering algorithm as a baseline. Its performance was compared to the performance of four of its accelerated variants. Four key design principles of accelerated clustering algorithms were identified. Further study and exploration of these principles led to four new and unique contributions to the field of accelerated fuzzy clustering. The first was the identification of a statistical technique that can estimate the minimum amount of data needed to ensure a multinomial, proportional sample. This technique was adapted to work with accelerated clustering algorithms. The second was the development of a stopping criterion for incremental algorithms that minimizes the amount of data required, while maximizing quality. The third and fourth techniques were new ways of combining representative data objects. Five new accelerated algorithms were created to demonstrate the value of these contributions. One additional discovery made during the research was that the key design principles most often improve performance when applied in tandem. This discovery was applied during the creation of the new accelerated algorithms. Experiments show that the new algorithms improve speedup with minimal quality loss, are demonstrably better than related methods and occasionally are an improvement in both speedup and quality over the base algorithm.

Le présent travail propose et développe une méthodologie complète d’identification des propriétés mécaniques locales d’un matériau hétérogène à l’échelle des phases constitutives. Il s’agit d’une combinaison de compétences très diverses, à la fois en théorique, en simulation numérique et en expérimentation. Plus précisément, la partie théorique concerne la détermination des relations nano-micro pour le module d’indentation homogénéisé par des techniques de changement d’échelle; la partie numérique basée sur la théorie du calcul à la rupture est réalisée en vue de trouver de ces dernières relations applicables pour la dureté; et la dernière partie est effectuée pour récupérer les propriétés homogénéisées par la voie expérimentale à l’aide de la technique de nano-indentation. L’étude expérimentale de la thèse est pour l’objectif de déterminer des propriétés d’indentation de différents échantillons de pâte de ciment. Un programme expérimental complet, est développé, qui permet de caractériser des phases principales à l’échelle micrométrique de ce matériau, parmi lesquelles nous nous intéressons surtout à celles plus importantes correspondantes à des phases de la matrice C-S-H. La modélisation du problème lié à l’enfoncement d’une pointe d’indentation dans un matériau est étudiée. Pour cela, la première voie, basée sur l’approche cinématique du calcul à la rupture, consiste à tenter de construire des mécanismes de ruine analytiquement, puis à les faire évoluer en fonction du changement de la géométrie initiale, afin d’obtenir la charge de ruine correspondante. La seconde voie consiste ensuite à suivre la même approche, mais en construisant numériquement ces mécanismes de ruine. La charge obtenue dépend naturellement des paramètres de critères retenus, que l’on détermine grâce à la combinaison avec les résultats expérimentaux. Les critères de résistance de Von-Mises et de Tresca valables pour des matériaux purement cohérents ainsi que celui de forme elliptique sont examinés dans ce travail

The present work proposes and develops a complete methodology for identifying the local mechanical properties of a heterogeneous material at the scale of the constitutive phases. It is a combination of very diverse skills in theory, in numerical simulation and in experimentation. More precisely, the theoretical part concerns the determination of the nano-micro relations for the indentation module; the numerical part based on the yield design theory is carried out to find the last relations applicable for the hardness; and the last part is performed to obtain homogenized properties by the experimental way using the nano-indentation technique. The experimental study of the thesis is for the purpose of determining indentation properties of different cement paste samples. A complete experimental program, is developed, which allows characterizing the main phases at the micrometric scale of this material, among which we are mainly interested in the C-S-H matrix phases. The modeling of the problem related to the penetration of an…

▼ Objectives of this study were to evaluate the associations of feed intake, feeding behavior, temperament, and carcass composition with performance and feed efficiency traits in growing heifers. Santa Gertrudis heifers (n = 369) with initial BW of (275.3 ± 37.4 kg) were used in this study. Intake and feeding behavior traits were collected for 70 d using a GrowSafe system while consuming a forage-based diet (ME = 2.19 Mcal/kg DM). Heifers were weighed at 14-d intervals and ultrasound traits measured on d 0 and 70. Residual feed intake was computed by regression of DMI on mid-test BW0^(.75) and ADG, and heifers classified into low, medium, and high RFI (± 0.50 SD) groups. A 2- population distribution model was fit to log10-transformed non-feeding interval lengths to estimate meal criterion (MC), which was used to compute meal traits (frequency and duration). As expected, RFI was positively correlated with DMI (r = 0.72; P < 0.001), but not with initial BW or ADG. Residual feed intake was negatively correlated with G:F (r = -0.72; P < 0.001) and RG (r = -0.49; P < 0.001). In contrast to previous studies, RFI was not correlated with ultrasound LM area or back-fat thickness measured on day 70 of the trials. Residual feed intake was positively correlated (P < 0.05) with bunk visit (BV) frequency (r = 0.45) and duration (r = 0.35), and meal duration (r = 0.31), but negatively correlated with MC (r = -0.25). The R^(2) of the base RFI model (ADG, mid-test BW0.75) was 0.48, which increased to 0.69 with the inclusion of backfat thickness and feeding behavior traits (BV frequency and duration, MC, meal frequency and duration, and time to bunk). Heifers with low-RFI phenotypes had 21.5 and 23.2% lower (P < 0.001) DMI and G:F compared to high-RFI heifers. Heifers with low RFI had lesser (P < 0.001) BV frequency (64.7 vs 80.6 ± 1.6 events/d) and duration (95.7 vs 113.4 ± 3.6 min/d), higher (P < 0.01) MC (9.45 vs 8.12 ± 0.55 min) and greater (P = 0.39) time to bunk (TTB; 67.9 vs 58.3 ± 3.5 min) compared to high-RFI heifers. Between-animal variation in RFI was not associated with differences in ultrasound measurements of carcass composition in this study. However, variation in feeding behavior traits account for 41% additional variance in DMI beyond that associated with carcass ultrasound, ADG, and mid-test BW0^(.75). The longer MC observed in low-RFI heifers suggests that these heifers take longer to initiate subsequent meals compared to high-RFI heifers, and demonstrate that heifers with divergent RFI have distinctive feeding behavior patterns.

▼ Data is categorical or numerical information that is collected and analyzed. Some examples of data are the company’s financial data or environmental data that can inform us of the state of the environment over time. Circumstances often lead to change. For example, the temperature globally has risen dramatically over the years, which began a phenomenon referred to as global warming. As a result, glaciers are rapidly melting, causing sea levels to rise. Rising sea levels damaging coastal areas with increase flooding and more frequent hurricanes.Nevertheless, if we can discover when the change occurred and what caused it, we can put reg-ulations and procedures in place to help avoid future damages. Determining the number of changes in a data set and when it occurred, is called the change point problem. Akaike (1973) introduced the Akaike information criterion (AIC) to solve the change point problem. Additional information criterion was introduced to expand upon and improve AIC. We will discuss AIC further, and we will utilize the Schwarz Information Criterion (SIC) and the Modified information criterion (MIC) to perform simulations on random lognormal distributed data.Chapter 1 introduces AIC and the binary segmentation procedure. Binary segmentation detects multiple change points in a data set. Note, the hypothesis test is employed to perform both AIC and binary segmentation procedures.Chapter 2 introduces SIC, then a theoretical basis and mathematical formulas are derived. Next, we use the criterion to administrate multiple simulations such as power tests and multiple sample size comparisons. Then we utilize SIC and the binary segmentation procedure to analyze the annual net flux of carbon to the atmosphere from land-use.Chapter 3 introduces MIC. Again, theoretical basis and mathematical formulas are derived. Multiple simulations are conducted, such as power test, sample size comparison, and information approach comparison. Lastly, we analyze historical cryptocurrency financial data using MIC with the binary segmentation procedure. This thesis aims to study the performance of the model selection information criterion and analyze the power of the change point detection procedure. We will do that through multiple simulations, conducted in chapters 2 and 3. Advisors/Committee Members: Ning, Wei (Advisor).

▼ Impact testing of vehicles and helmets is performed under the specifications of a test protocol to ensure that regulatory standards and community expectations are met in terms of head injury safety. Impact severity is usually measured using the acceleration of the impactor (or dummy head) that is recorded during the impact. A specification that is defined in these testing protocols is the injury response function (irf) that is used to summarise the magnitude of the recorded acceleration. There are various irfs that can be chosen to summarise the acceleration data. This thesis examines several of these irfs that are based on linear acceleration. The aim was to describe the differences between the irfs and examine what differences might arise in the designs in response to the requirements of the irf. There has historically been disagreement on the best way to assess injury risk, but the debate is only important to the extent that the design requirements are affected by the choice of irf. Four irfs were examined in detail. These were the Head Injury Criterion (HIC), the Peak Virtual Power (PVP), the 3 millisecond clip (ɑ₃) and the peak acceleration (ɑ m[subscript]). Simple acceleration pulse shapes were used to determine some of the properties of each of the irfs. These included the role of the pulse shape, the stopping distance, the impact velocity and the coefficient of restitution on the value of each of the irfs. The effect of the pulse shape on the value of the irfs was examined using these simple pulse shapes that had been normalised for a constant impact velocity and stopping distance. Equations predicting the value of each irf were then derived that used the stopping distance, the impact velocity and the coefficient of restitution as predictors. The properties found using the simple pulse shapes were then examined using the real test data that included 247 tests obtained from a pedestrian testing protocol. The predictions of the equation for each irf were compared to the test data using a linear regression. The remaining variation in the value of each irf was attributed to the effect of the pulse shape. In most cases, the measured relative severities of the impacts were not greatly affected by the choice of irf, but there were some discrepancies. The characteristics of the pulse shapes that gave rise to these discrepancies were identified. These were identified by subtracting the effect of the stopping distance, the impact velocity and the coefficient of restitution from the value of the irf for each test to determine an adjusted irf value for each test. These adjusted irf values were ranked and compared to determine the discrepant tests. Differences in the magnitude of the effect of the pulse shape, the maximum stopping distance, the impact velocity and the coefficient of restitution on the value of each of the irfs were found theoretically and these were verified in the experimental data. The effect of the choice of threshold on determining the tests that were considered ‘safe’ and ‘unsafe’ was also examined.… Advisors/Committee Members: Anderson, Robert William Gerard (advisor), Hutchinson, Timothy Paul (advisor), Centre for Automotive Safety Research (CASR) (school).

▼ A central question in theories of massive star formation is how massive stars gain their mass. Two of the ways in which this can be investigated are via studies of the infall activity and substructure in massive star forming regions. Blue asymmetric spectral line profiles are frequently used as an indicator of infall in star forming regions. In the first part of this thesis we investigate infall in 11 high mass protostellar infall candidates. We assess the spectral asymmetry in IRAM 30m observations of 9 point maps in the optically thick HCO⁺(1-0) transition. Where infall is detected, we calculate infall velocities using the two-layer infall model. We find 6 sources with predominantly blue asymmetry in their HCO⁺spectra, providing the strongest evidence for infall. The 5 remaining sources show red asymmetry in 11-38% cases. Where infall is detected we calculate infall velocities in the range 0.12â€“8.38 km/s, corresponding to mass infall rates between 1x10^-4â€“ 9x10^-3 M/yr, typical of the higher accretion rates seen in massive star forming regions. We conclude that a single central observation of blue asymmetry towards the centre of a source does not necessarily translate in to blue asymmetry at all offset positions around the source. Spectral line maps, showing blue asymmetry at multiple off set positions around a source, provide stronger evidence for infall and can also tell us how infall velocity varies with position. Based on comparisons between the HCO+ maps and JCMT ¹²CO(3-2) and ¹³CO(3-2) observations, showing the outflow activity in each source, we strengthen the case for infall in 5 sources, finding blue asymmetry across the full extent of their HCO+ maps, which may also indicate that infall in occurring on a large scale. Further work is required to calculate outflow properties, and determine the variation of infall velocity with molecular tracer, allowing the properties of the infall to be further constrained. In the second part of this thesis we study the substructure in the two largest fragments, MM1 and MM2, in the IRDC SDC13. As MM1 appears to be in a later stage of evolution than MM2, comparing their substructure provides an insight into massive clump evolution. Investigations into the substructure of massive star forming regions are essential for understanding relationships between the CMF and the IMF. We report the results of high resolution SMA dust continuum observations towards MM1 and MM2, and carry out RADMC-3D radiative transfer modelling to characterise the observed substructure. The continuum results indicate the presence of 4 sub-fragments in the SDC13 region. The nature of the second brightest sub-fragment (B) is uncertain as it does not have a corresponding feature at the lower resolution or at other wavelengths. MM1, which is actively forming stars, consists of two sub-fragments A and C. This is confirmed by 70 micron Herschel data. While MM1 and MM2 appear quite similar in previous low resolution observations, at high resolution, the sub-fragment at the centre of MM2… Advisors/Committee Members: Fuller, Gary.

▼ Protoplanetary disks set the physical and chemical conditions for the planets that will eventually form inside of them. While the exact details of the process remain a large area of research, it is the gas and dust in these disks that will grow into planets. By the Class II phase of a protostar’s evolution, large disks are common (so there is a large mass reservoir available) and it is commonly assumed that most of the planet formation process occurs at this time. However, with the advent of high-sensitivity interferometers, such as the VLA or ALMA, we are finding that large disks can grow even at the earliest times of a protostars life (Class 0 phase). These young objects are heavily obscured in their dusty natal envelope and often carry information from the cloud with them (i.e., the local magnetic field). In fact, theoretical studies have shown that these fields can directly influence whether a disk can grow in Class 0 sources. Through observational studies of both evolved and young protostars, the research presented in this dissertation concentrates on observing planet formation via grain growth inferred by disk substructure, examining the role magnetic fields have in the youngest sources, and probing the way magnetic fields are traditionally inferred. I first present an unbiased survey of the evolved disks in the ρ Ophiuchus cloud using ALMA. I measured the flux and radius from ∼ 50 pre-main-sequence stellar systems. I found that binary systems are both dimmer and have smaller disks than their isolated components. I used these results to test if these disks were smaller due to tidal truncation, and found that the disks surrounding binaries in this cloud are too small to have been affected by truncation. This survey also revealed six transition and gapped disks, indicating active planet formation in these sources. I then present work examining the magnetic fields of the Class 0 protostar, IRAS 4A, to infer disk growth at young stages. This is the first result of the VANDAM survey and uses dust continuum polarization to infer the projected magnetic field morphology at disk-scales. I show that the inferred field has an azimuthal pattern, which appears to be from the field lines being dragged down to a rotating disk. Since this source is very well studied, I use previous sub-/millimeter flux data to show that large (∼ cm size) dust grains have grown in the 10kyr age of IRAS 4A. Then I show the results from an ALMA polarization study of ten protostars. Here we looked at dust continuum polarization observations of 3 sources that are candidate disks from 8 mm data, 2 sources that are likely fragmenting disks, 1 close binary and 4 sources that do not have discernible disks down to ∼ 12 au. I found that all sources show ordered polarization, as well as a low polarization fraction, in the inner ∼ 150 au and that outside of that radius, the polarization becomes higher and more disordered. The disk candidates all show a polarization morphology that is akin to self-scattering in the disk region. However, this… Advisors/Committee Members: Looney, Leslie (advisor), Looney, Leslie (Committee Chair), Gammie, Charles (committee member), Liu, Xin (committee member), Wong, Tony (committee member).

▼ Les nouvelles méthodes de navigation durant le Moyen Age. Le navire de commerce à voile est propulsé par le vent et doit donc suivre cette direction générale. La navigation peut se définir selon un aspect d’abord stratégique comme le choix d’une route en tenant compte des contraintes imposées par le vent et un aspect tactique concernant le tracé et le contrôle, en cours d’exécution de cette route. 1-Dans un premier temps, la navigation antique ne se réfère qu’au seul vent qui est le moteur mais aussi le guide du navigateur pour suivre la route fixée par l’observation des traces qu’il imprime sur la mer. C’est la navigation à vue. La limite de la méthode est atteinte quand le vent devient changeant au large, ce qui oblige alors une vérification de la direction par l’observation des astres. 2- L’apparition de l’aiguille aimantée résout en partie ce problème. L’orientation géographique entraine la mise au point, à la fin du XIIIe siècle, d’une nouvelle méthode : l’estime. L’estime est la résolution graphique des problèmes que pose le contrôle de la route choisie. Cette résolution suppose, d’une part, l’usage de la boussole et d’une orientation géographique et, d’autre part, une analyse vectorielle sur un support la carte marine qui est donc indissociable de la méthode. Le plus gros défaut de l’estime est que les positions sont définies par projection dans le futur de paramètres, cap et distances parcourues actuels. Des différences sont donc à prévoir qui entrainent une zone d’incertitude sur le point estimé. 3- Lorsqu’au début du XVe siècle les navigateurs se lancent dans l’inconnu, obligés de suivre le vent qui décrit des boucles, les voyages s’allongent sans voir la terre pour une confrontation avec des positions avérées. La taille des zones d’incertitude obligent le navigateur a préciser sa position finale par d’autres méthodes basées sur des observations astronomiques. On peut distinguer deux méthodes : Tout d’abord, la méthode des hauteurs de polaire, de 1433 à 1480 environ, qui permet de finaliser la volta et d’effectuer un atterrissage selon une route Est-Ouest. L’analyse de la technique nautique de Colomb, qui utilise cette méthode, est très semblable à celle décrite par Ibn Majid dans son traité de navigation. Il est probable qu’il y a eu transmission sans pouvoir préciser les circonstances exactes.Mais dès que les navigateurs franchissent l’équateur la polaire devient indisponible, les navigateurs doivent observer le soleil. Cette deuxième méthode est plus délicate car les paramètres du soleil changent chaque jour. Ils obligent donc le navigateur à calculer la latitude, à partir de l’observation de la méridienne de soleil et par l’usage de tables des données solaire : os regimentos do sol. C’est cette méthode qui permet à Vasco da Gama de doubler le cap de Bonne Esperance, en 1498, ce qui marque la fin de la période étudiée. Pour conclure il faut remarquer que ces deux derniers méthodes sont le fruit d’une coopération entre les usagers et les scientifiques sous l’égide du pouvoir, décidé à atteindre le but… Advisors/Committee Members: Guillerme, André (thesis director).

Les virus dits émergents sont aujourd’hui responsables de crises sanitaires majeures, en témoignent les récentes épidémies d’Ebola, de Chikungunya, ou du virus de la grippe A (H1N1). Des traitements antiviraux efficaces et sûrs sont donc toujours d’intérêt majeur. Au cours des dernières décennies, les analogues de nucléosides se sont révélés être de précieux alliés dans la lutte contre de nombreuses pathologies virales parmi lesquelles le virus du SIDA, celui de l’Hépatite C ou de l’Herpès.Récemment, le développement de C-nucléosides, présentant une position anomérique quaternaire, a permis d’obtenir des résultats prometteurs contre ces «nouveaux» virus. Au cours de ces travaux de thèse, réalisés en collaboration avec les laboratoires Janssen, nous avons mis au point de nouvelles voies d’accès à ces composés originaux, en exploitant la chimie des C-nucléosides. Une nouvelle famille d’analogues comportant les motifs 1,2,3-triazoleet cyano en position anomérique a notamment été préparée en utilisant la chimie “Click” et les couplages C-Cmétallo-catalysés.

As witnessed by recent Ebola, Chikungunya or Influenza (H1N1) breakthroughs, emerging an re-emerging viruses are still responsible for major health crisis. Efficient and safe antiviral therapies are thus highly needed. Over the past decades, nucleoside analogs have lead the fight against manyof those pathogens, including: HIV, HCV or HSV. Recently, C-nucleoside analogs bearing a quaternary anomericposition have emerged as promising antiviral drugs against these «new» viruses.There are still very few ways to access to such motif in the literature. In the course of this PhD thesis, collaborating with Janssen laboratories, we have developped new strategies to reach these originals scaffolds, relying on C-nucleosides chemistry. Notably, we have synthesized a familly ofanalogs, having a 1,2,3-triazole and a cyano group attheanomeric position, exploiting “Click” chemistry and metallo-catalyzed C-Ccouplings.

▼ This thesis is a collection of essays on matching and resource allocation problems. In Chapters 1 and 2, we study college admission. Each college has strict preferences over sets of students, and each student has preferences over colleges. In Chapter 1, we allow monetary transfers, e.g., students may receive stipends from colleges. We specify a fixed budget for each college. The preferences of the students are over college-stipend bundles. We define pairwise stability. We construct an algorithm. The rule defined through this algorithm is not only pairwise stable but also incentive compatible for the students. In Chapter 2, we consider a central exam students should take. We allow different students to receive the same scores. We define and study an eligibility criterion. Students are divided into two groups: those who are eligible to apply to colleges, and those who are not. Eligibility respects the students’ scores. We introduce three notions of stability that respect eligibility. We define three new rules, each of which satisfies a different notion of stability. We also study an incentive compatibility requirement. Chapters 3 and 4 investigate the implications of a robustness principle for different resource allocation problems. In Chapter 3, we study the problem of assigning a set of objects, e.g., houses or tasks, to a group of individuals having preferences over these objects. We may observe cases when there are more or fewer of objects to be allocated than was planned. We formulate these changes in two new robustness properties. We characterize the family of rules that satisfy either of these properties, together with efficiency, fairness and incentive compatibility requirements. They are the sequential priority rules. In Chapter 4, we study the problem of allocating a divisible good among a group of people. Each person’s preferences are single-peaked. Here too, we may observe the cases when there might be more or fewer of resources to be allocated than was planned. We formulate changes in a robustness property. We show that there is a unique rule that is efficient and fair, and satisfies our composition property. This rule is the uniform rule.

Subjects/Keywords: Pairwise stability; Eligibility criterion; Robustness requirement.

The work is intended to study the argument structures of Urdu and English verbs to bring out the basic difference, if any, between these two languages in this regard. It explains why such a study is necessary. It begins with a theoretical discussion on what has already been done within the framework of Principles and Parameters theory and the Minimalist Program. It cusses theta roles required by verbs in Urdu and English and compares them to find out the ways in which they are similar to or different from each other. The First Chapter deals with some theoretical issues that led to the volution of the theta theory within the principles and parameters theory Chomsky 1981). It discusses the significance of theta theory for the ellformedness and semantic interpretation of a sentence. It discusses briefly the crucial justification for thematic relations given by Gruber (1976, (originally 1965)) which was followed by Jackendoff’s conceptual approach to the thematic relations (1990). Further it has discussed how Chomsky’s concept of thematic structure is different from Jackendoff’s conceptual structure. It argues that Chomsky’s theta theory offers a more satisfactory solution than Jackendoff’s in so far as the hematic structures of sentences of natural languages are concerned. The theta criterion which is an important component of theta theory has been discussed in details. It retains its significance even in the Minimalist Program which questions almost every assumption of Principles and Parameters theory. Chomsky notices that Theta roles are a fundamental property of grammar and their proper assignment to the arguments is necessary to satisfy the principle of Full Interpretation (FI); otherwise a derivation gets crashed. The chapter presents the aims and objectives of this work and argues that the comparative study of the thematic structures in Urdu and English is essential to understand the problem faced by the native speakers of Urdu learning English as a second language. The Second Chapter contains detail of the possible theta roles of Urdu and English verbs. It assumes the hypothesis that verbs of similar semantic types in different languages have similar argument structures at LF but all of them are not expressed the same way at PF.
