Texte intégralRésumé :
No Instituto de Zootecnia, Nova Odessa, SP, em uma pastagem de capim-aruana (Panicum maximum Jacq. cv. Aruana) utilizada com ovinos em sistema intensivo de produção (irrigação, adubação e lotação rotacionada), foram sobre-semeadas as espécies forrageiras de inverno: aveia preta (Avena strigosa Schreb cv. Comum), azevém anual (Lolium multiflorum Lam. cv. Comum) e trevo branco (Trifolium repens L. cv. Zapicán) com o objetivo de suprir o déficit e melhorar o valor nutritivo da forragem no período crítico do ano. A sobre-semeadura foi efetuada em 14/04/00 e 07/06/01 no primeiro e segundo anos do experimento, respectivamente. Nos dois anos (14/04/00 a 18/01/01 e 07/06/01 a 22/02/02) foram avaliados, em seis períodos de pastejo: massa total de forragem pré-pastejo, sua composição botânica e porcentagem de lâminas foliares, massa de forragem pós-pastejo, acúmulo de forragem (AF) e taxa média diária de acúmulo de forragem (TMDAF) em cada período de rebrotação, altura do dossel forrageiro pré e pós-pastejo, características químicas: proteína bruta (PB), fibra em detergente neutro (FDN), fibra em detergente ácido (FDA), lignina e digestibilidade in vitro da matéria seca (DIVMS), nas amostras da massa total de forragem e nas dos componentes botânicos (aruana, aveia preta e azevém) pré-pastejo. O delineamento experimental foi o de blocos completos casualizados (quatro), com duas repetições dentro do bloco e dois tratamentos: 1) capim-aruana exclusivo (AE) e 2) sobre-semeadura da mistura das três espécies forrageiras de inverno (MFI). Os blocos eram pastejados pelo mesmo lote de animais, em sequência, por dois a três dias, até atingir 10 a 15 cm. O trevo-branco não se estabeleceu em ambos os anos. No primeiro ano, a pastagem MFI apresentou maior massa total de forragem do que a pastagem AE no segundo período e na média dos seis períodos. A aveia apresentou a maior contribuição no segundo período e o azevém no terceiro. As pastagens com a MFI apresentaram maiores AF e TMDAF que as pastagens de AE no segundo, quinto e na média dos seis períodos. A PB da forragem na pastagem de capim-aruana exclusivo foi maior em relação à sobre-semeada no terceiro período de pastejo e semelhante nos demais. A PB dos componentes aveia e azevém, no terceiro período, foi menor em relação aos do primeiro e segundo. FDN, FDA e lignina da forragem no tratamento exclusivo foram mais elevados em relação aos do tratamento sobre-semeado, na média dos seis períodos. Aveia e azevém apresentaram FDN mais baixos nos períodos iniciais de crescimento, com aumento no último. A digestibilidade da forragem foi semelhante nos dois tratamentos, em todos os períodos de avaliação. No segundo ano, a massa total de forragem apresentou quantidades semelhantes entre as duas pastagens ao longo dos seis períodos e na sua média. A aveia esteve mais presente no primeiro período e o azevém no terceiro. Não houve diferença entre tipos de pastagem para AF e TMDAF em nenhum dos seis períodos, nem na sua média. Para o componente aruana a porcentagem de lâminas foi semelhante entre os dois tipos de pastagem e para a aveia e azevém, as menores porcentagens ocorreram no período final dos seus ciclos vegetativos, em ambos os anos. O teor de PB da massa total de forragem da pastagem de capim-aruana exclusivo foi maior que o da pastagem sobre-semeada, no quarto período mas semelhante nos demais e na média dos períodos. Os teores de PB da aveia e do azevém decresceram ao longo dos períodos de pastejo. Os teores de FDN, FDA, lignina e DIVMS da forragem foram semelhantes entre as duas pastagens na média e ao longo dos seis períodos, exceto para FDN no segundo período. A aveia e o azevém apresentaram os maiores teores de FDN, FDA e lignina no último período de pastejo. A DIVMS do azevém manteve-se constante nos dois primeiros períodos de pastejo diminuindo no último. Pastos de capim-aruana convenientemente adubados e irrigados, que recebam sobre-semeadura com espécies forrageiras de inverno, produzem mais forragem no período crítico mas com valor nutritivo semelhante em relação a pastos não sobre-semeados, nas condições do Estado de São Paulo. Pastos deste capim, não sobre-semeados, mas que recebam adubação e irrigação também apresentam boa produção e valor nutritivo nesta época.At Instituto de Zootecnia, Nova Odessa, SP, in a pasture of aruanagrass (Panicum maximum Jacq. cv. Aruana), grazed by sheep in an intensive production system (irrigation, fertilization and rotational stocking), it was introduced a three winter forage species: black oat (Avena strigosa Schreb. cv. Common), italian ryegrass (Lolium multiflorum Lam. cv. Common) and white clover (Trifolium repens L. cv. Zapican) with the objective of increasing the forage supply and its nutritive value during the dry winter period. The mixture was broadcasted sown over the grass on 04-14-00 and 06-07-01 in two years of experiment. From 04-14-00 to 01-18-01 and 06-07-01 to 02-22-02 it was evaluated, in six annual grazing periods, the forage mass, its botanical composition and leaf blades percentage pre grazing, residual mass post grazing, forage accumulation (FA) and mean forage accumulation daily rate (MFADR) in each regrowth period and sward heigth pre and post grazing, the chemical characteristics: crude protein (CP), neutral detergent fiber (NDF), acid detergent fiber (ADF), lignin and in vitro dry matter digestibility (IVDMD) in the forage on offer and in its botanical components. The experimental design was a completely randomized block (four) with two replications within the block. The treatments were: 1) grass alone and 2) the grass oversown with the mixture of the winter forages. The blocks were grazed by the same group of sheep in sequence for two or three days until the sward height reached to 10-15 cm. The white clover did not establish. In the first year the oversown treatment presented higher total forage mass than the control in the second periods and in the mean of the six periods. The black oat presented higher contribution in the second period and italian ryegrass in the third. The oversown pastures presented higher FA and MFADR than the single aruanagrass pastures, in the second, fifth and in the mean of the six periods. The CP in the forage from the grass pasture alone was greater than the one of the oversown pasture in the third period, and similar in the others. Oat and ryegrass CP was lower in the third period than the ones of the first and second ones. NDF, ADF and lignin in the forage from the grass pasture alone were greater than the ones of the oversown pasture. Oat and ryegrass NDF was lowest in the initial growth periods, increasing in the final. Forage IVDMD from the two treatments were similar in all evaluation periods. In the second year, the total forage mass was similar in the two pasture treatments in all grazing periods and in their means. The black oat contribution was higher in the first period and the one of italian ryegrass in the third. The FA and the MFADR were similar in the two pasture systems. The leaf blades percentage of aruanagrass was similar in the two pastures in all periods and the ones of black oat and italian ryegrass were lower in the final period compared to the preceeding ones, in the two years. The CP in the forage from the grass pasture alone was greater than the one of the oversown pasture in the fourth period, and similar in the others. Oat and ryegrass CP decreased along the grazing periods. NDF, ADF, lignin and IVDMD of the forage from the two treatments were similar in all evaluation periods. Oat and ryegrass NDF, ADF and lignin were greater in the last grazing period. Ryegrass IVDMD from the first two periods were similar and decreased in the final. For the São Paulo State conditions, adequately fertilized and irrigated aruanagrass pastures, when oversown with winter annual forages, yield more than single aruanagrass ones during the dry winter period but with similar nutritive value. Single aruanagrass pastures when fertilized and irrigated present also good forage yields with good nutritive value during this time.

Texte intégralRésumé :
This report looks closer on the physics of black holes and their related phenomena. Particularly, this report studies a certain black hole called Gargantua that is portrayed in the movie Interstellar. By using this as a source of inspiration we look at Gargantua’s effect on time, planetary orbits and tidalforces. The following report showed that the physics studied here corresponded fully to the physics represented in Interstellar, making the movie very credible from a physics point of view. I show that the black hole portrayed in Interstellar needed to spin at a rate of 1.33*10^-14 percent less than its maximum possible to achieve a timedilation of 61320 at the distance where stable planetary orbits are found. At a spin this high, planets can have stable orbits as close as half the Schwarzschild radius which means they are located just outside the event horizon of a maximally rotating black hole. The enormous timedilation at planets orbiting near the event horizon is a result of the planets close proximity to the black hole, its orbital velocity and frame dragging. Frame dragging describes the effects on spacetime on account of the rotation of the black hole. Looking at the tidal forces on objects surrounding the black hole it was found that an increasing mass would actually decrease the tidal forces on objects outside the event horizon. For a sufficiently large mass on the black hole, a planet could avoid being ripped apart but this restricted its size to a radial extension of about 5500 km which corresponds to 0.86 earth radiuses.

Bickerstaff, Jovonne J. « Together, Close, Resilient : Essays On Emotion Work Among Black Couples ». Thesis, Harvard University, 2015. http://nrs.harvard.edu/urn-3:HUL.InstRepos:17467493.
Texte intégralRésumé :
Emotional intimacy and support are deemed vital to most individuals’ sense of relationship quality and satisfaction. Although relationship outcomes are more closely tied with partners’ sense of emotional well-being in their partnerships, most sociological inquiry focuses on how couples navigate instrumental tasks of family work (e.g. household work, childcare, etc.). Examinations of emotional facets of couple relationship remain rare. This dissertation addresses this dearth by presenting an inductively derived analysis of how black heterosexual spouses in enduring relationships (10-40 years) sustain emotional connection. It draws on 75 semi-structured interviews - with relationship professionals (n=12) and 42 black spouses (21 couples) interviewed jointly and individually (n=63) from New York, Cleveland, and Chicago. Using a sociology of emotion lens, it extends Arlie Hochschild’s conceptual framework of emotion management by examining emotion work along four dimensions. First, challenging gender essentialism in extant research, it examines partners’ desires for, perceptions of and approaches to intimacy going beyond a discussion of gender differences to also shed light on overlap between and variation within gender groups. Secondly, it shows how the co-creation of joint emotion strategies to avoid or confront recurrent interpersonal tensions helped couples solidify a shared sense of couple identity marked by different degrees of we-ness. Third, contrary to previous studies suggesting it’s mainly women who do emotion work on themselves to manage dissatisfaction with intimacy, I reveal how both spouses engage in emotion work when connection breaks down. Often, such emotion work often arises due to tensions between the carework of intimacy and pre-existing norms and beliefs around emotional engagement. Finally, probing particularities in black women’s socialization around resilience, I disturb the monolithic portrait of women as intimacy experts in extant research, underlining challenges they face beyond dissatisfaction with male emotionality. By focusing on black couples, the study expands the demographic terrain of qualitative sociological inquiry on emotion work and couple relationships writ large. Finally, by theorizing from the experience of black couples, I disturb trends of taking educated, white, middle class couples as the normative American family, revealing how our conceptualization of emotion work could benefit from better accounting of social positionality.Sociology

Texte intégralRésumé :
High-mass X-ray binaries (HMXRBs), such as Cygnus X-1, host some of the most rapidly spinning black holes (BHs) known to date, reaching spin parameters a greater than or similar to 0.84. However, there are several effects that can severely limit the maximum BH spin parameter that could be obtained from direct collapse, such as tidal synchronization, magnetic core-envelope coupling, and mass loss. Here, we propose an alternative scenario where the BH is produced by a failed supernova (SN) explosion that is unable to unbind the stellar progenitor. A large amount of fallback material ensues, whose interaction with the secondary naturally increases its overall angular momentum content, and therefore the spin of the BH when accreted. Through SPH hydrodynamic simulations, we studied the unsuccessful explosion of an 8 M-circle dot pre-SN star in a close binary with a 12 M-circle dot companion with an orbital period of approximate to 1.2 days, finding that it is possible to obtain a BH with a high spin parameter a greater than or similar to 0.8 even when the expected spin parameter from direct collapse is a less than or similar to 0.3. This scenario also naturally explains the atmospheric metal pollution observed in HMXRB stellar companions.

Carbon Black-doped Polydimethylsiloxane (CB-PDMS) can be used as a pressure sensing material due to its piezoresistive properties. The sensitivity of such a sensor is in part dependent on the stiffness of the material. A closed-cell CB-PDMS foam is being explored as a possible flexible, lightweight, and waterproof underwater sensing material for use in unmanned underwater vehicles and other hydrodynamic sensing purposes. The percolation threshold for conduction through the CB-PDMS foam is theorized, and a number of different concentrations based on the theorized threshold are explored in order to determine the optimum weight percent of Carbon Black dopant to achieve a high sensitivity, low stiffness sensing CB-PDMS foam. Sinusoidal mechanical pressure patterns were applied and voltage response measured. An optimum dopant weight percent out of the concentrations tested was found at 5.5 wt% CB-PDMS.

Code clone Discovery Based on Functional Behavior
by
Ronald M Krawitz
2012
Legacy programs are used for many years and experience many cycles of use-maintenance-use-maintenance-use-etc. Source code or source code functionality is frequently replicated within these programs when it is written, as well as when it is maintained. Over time many different developers with greater or lesser understanding of the source code maintain the source code. Maintenance developers, when they have limited time or lack understanding of the program, frequently resort to short cuts that include cutting and pasting existing code and re-implementing functionality instead of refactoring. This means a specific functionality is often repeated several times, sometimes using different source code. Blocks of replicated source code or source code functionality are called code clones. Removing code clones improves extensibility, maintainability, and reusability of a program in addition to making the program more easily understood.
It is generally accepted that four types of code clones exist. Type-1 and Type-2 code clones are comparatively straightforward to locate and tools exist to locate them. However, Type-3 and Type-4 code clones are very difficult to locate with only a few specialized tools capable of locating them with a lower level of precision.
This dissertation presents a new methodology that discovered code clones by studying the functional behavior of blocks of code. Code Clone Discovery based on Functional Behavior (FCD) located code clone by comparing how the blocks of code reacted to various inputs. FCD stimulated the code blocks with the same input patterns and compared the resulting outputs. When a significant portion of the outputs matched, those blocks were declared to be a code clone candidate. Manual analysis confirmed that those blocks of code were code clones. Since FCD discovered code clones based on their black-box behavior, the actual source code syntax was irrelevant and manual inspection further confirmed FCD located code clones that included Type-3 and Type-4 code clones which are frequently excluded from code clone detection tools. FCD recognized the code clones regardless of whether or not they use identical code, similar code, or totally dissimilar code. This new technique allows for an improvement in software quality and has the potential to significantly reduce the cost of software over its lifetime.

Texte intégralRésumé :
In this thesis, black-box models describing the quadcopter system dynamics for attitude control have been estimated using closed-loop data. A quadcopter is a naturally unstable multiple input multiple output (MIMO) system and is therefore an interesting platform to test and evaluate ideas in system identification and control theory on. The estimated attitude models have been shown to explain the output signals well enough during simulations to properly tune a PID controller for outdoor flight purposes. With data collected in closed loop during outdoor flights, knowledge about the controller and IMU measurements, three decoupled models have been estimated for the angles and angular rates in roll, pitch and yaw. The models for roll and pitch have been forced to have the same model structure and orders since this reflects the geometry of the quadcopter. The models have been validated by simulating the closed-loop system where they could explain the output signals well. The estimated models have then been used to design attitude controllers to stabilize the quadcopter around the hovering state. Three PID controllers have been implemented on the quadcopter and evaluated in simulation before being tested during both indoor and outdoor flights. The controllers have been shown to stabilize the quadcopter with good reference tracking. However, the performance of the pitch controller could be improved further as there have been small oscillations present that may indicate a stronger correlation between the roll and pitch channels than assumed.

Texte intégralRésumé :
The focus of this thesis is to exploit closed-loop space–time block coding schemes designed for multiple antenna links composed of four transmit antennas within collaborative wireless networks. Such schemes have the potential to increase the end-to-end bit error rate performance of wireless networks as compared to established schemes which only include links composed of two transmit antennas. The two four transmit antenna closed-loop space–time block codes (STBCs) considered are the closed-loop quasi-orthogonal STBC (CL-QO-STBC) and the closed-loop extended-orthogonal STBC (CL-EO-STBC) schemes. Both techniques benefit from linear decoding complexity and symbolwise maximum likelihood decoding.

Educational AdministrationEd.D.
The Crumpton School District (CSD) is a high performing school district in suburban Philadelphia that has expended a great deal of energy and work to close gaps in the achievement of its Black students. Despite these efforts, 2016 standardized test data reflect a reading achievement gap of 28 percentage points for Black boys attending four of the CSD schools with the largest percent of Black boys enrolled. This qualitative study was designed to provide the CSD with implications for practice to continue and improve its work related to increasing the reading achievement of Black boys. More specifically, this study examined educators’ perceptions of the effectiveness of strategies and conditions in place to close the reading achievement gap of third grade Black boys. This study also examined the roles of CSD administrators in their efforts and plans for closing the reading achievement gap of third grade Black boys. Individual interviews of 11 third grade teachers, seven reading specialists, four special education teachers, four curriculum specialists, three principals, one assistant principal, one supervisor of special education, and one supervisor of communication arts, as well as the review of principal’s school improvement plans and goals, were the sources of the qualitative data. Detailed analyses of the qualitative data collected provided recommendations for teachers and educators of CSD to improve the manner by which they provide Black boys with equitable opportunities to achieve in the area of reading. These recommendations, hopefully, could benefit similarly situated districts in the state and nation.

Texte intégralRésumé :
The management of Sclerotinia stem rot of soybean caused by [Sclerotinia sclerotiorum (Lib) de Bary] integrates several tactics that may include biological control. However, the successful incorporation of biocontrol agents into the management program might be hindered by agrochemical application. To determine the compatibility of potential biocontrol agents with agrochemicals, growth of Trichoderma asperellum, T. gamsii and Coniothyrium minitans was tested with selected chemicals on agar plates. Effects of selected agrochemicals on C. minitans growth and biocontrol activity were also tested in soil and in water. On amended agar media, Trichoderma spp. and C. minitans were insensitive to the herbicide lactofen and were inhibited to varying degrees by some of the tested fungicides. The survival and the biocontrol activity of C. minitans in the soil was not impaired by propamocarb HCl, tetraconazole or lactofen treatments. When mixed in a water suspension, none of the selected the herbicides or a biofertilizer affected C. minitans population in the suspension over a 4 h period, suggesting that they can be applied in a tank mix. Under field conditions, Trichoderma spp. and C. minitans reduced the disease severity and viable sclerotial population of S. sclerotiorum, but their efficacy varied across years and location. Co-application with lactofen enhanced the efficacy of disease suppression and yield in some cases but reduced the efficacy in others. The effect of the biological control agents or chemicals evaluated on yield during three years of trials was inconsistent.

Texte intégralRésumé :
A Terra Preta Antropogênica (TPA) tem essa denominação porque é encontrada em sítios arqueológicos, onde viveram grupos pré-históricos e é considerada um dos solos mais férteis do mundo. Nela é encontrada grande quantidade de material deixado por grupos indígenas como fragmentos cerâmicos, artefatos líticos, e especialmente carvão pirogênico. Estudos realizados com o carvão pirogênico verificaram que ele aumenta a capacidade de trocas catiônicas nesses solos. Por meio de microscopia de fluorencência, foi observada a presença de microrganismos habitando esse carvão, no entanto, não se sabe quais seriam. Devido à falta de informações sobre a diversidade bacteriana nessas estruturas, este trabalho estudou a diversidade bacteriana em amostras de carvão pirogênico de solos TPA coletadas nos sítios Lagoa Balbina (Amazônia Central- Amazonas) e Mina I (Amazônia Oriental - Pará), através de técnicas moleculares independentes de cultivo. O estudo visou também comparar essa diversidade com a encontrada no solo de onde carvão foi isolado. As estruturas de carvão foram separadas fisicamente dos solos e seu DNA genômico total extraído e usado como molde em reação de PCR utilizando oligonucleotídeos do gene 16S rRNA para o Domínio Bacteria. O produto da PCR foi clonado em vetor e os clones foram sequenciados e comparados com o banco de dados de 16S rRNA do RDPX. Com a construção das bibliotecas de clones do gene 16S rRNA a partir das amostras de carvão pirogênico observou-se que existe maior número de bactérias desconhecidas no carvão pirogênico do que no solo onde ele foi isolado. Acidobacteria foi o filo predominante nas bibliotecas de carvão pirogênico das duas localidades de estudo, assim como na biblioteca do solo do sítio Mina I. Já na biblioteca do solo do sítio Lagoa Balbina houve predominância do filo Firmicutes. Por meio do método de rarefação foi possível constatar uma menor riqueza de UTOs nas comunidades bacterianas presentes nas estruturas de carvão pirogênico quando comparado à riqueza de UTOs das comunidades bacterianas cujo habitat é o solo. Mas quando se compara a riqueza de UTOs entre as estruturas de carvão isoladas das duas localidades, observa-se que a riqueza é maior no sítio Mina I. Os valores obtidos com os índices de diversidade revelaram menor diversidade de UTOs nas bibliotecas obtidas para o carvão pirogênico das duas regiões estudadas se comparado dos valores para as bibliotecas obtidas do solo da mesma região. Os valores obtidos com os métodos não paramétricos revelaram maior riqueza de UTOs para as bibliotecas do carvão do sítio Mina I e solo TPA do sítio Balbina. A análise da PCA revelou que as bibliotecas do sítio Balbina mostraram-se altamente similares. Em adição, a análise com S-Libshuff, verificou que todas as bibliotecas comparadas são significativamente diferentes quanto à composição das comunidades bacterianas. O carvão pirogênico não é uma estrutura inerte, pois é capaz de ser habitado por diferentes bactérias e a sua estrutura da comunidade bacteriana é diferente daquela de onde ele foi segregadoAnthropogenic Dark Earth (ADE) has this denomination because it is found at archeological sites, where prehistoric groups lived, and it is considered one of the most fertile soils of the world. In this soil a great amount of material left by indigenous groups was found as ceramic fragments, lithic workmanships, and especially pyrogenic black carbon. Studies accomplished with the pyrogenic black carbon verified that it increases the capacity of cationic changes in soils. Through fluorescence microscopy, the presence of microorganisms was observed inhabiting that black carbon, however, this community is still unknown,due to the lack of information about the bacterial diversity in those structures.This work studied the bacterial diversity in samples of pyrogenic black carbon of ADE soils, collected at the sites Lagoa Balbina (Central Amazon) and Mina I (Oriental Amazon), through molecular techniques independent of cultivation. The study also sought to compare that diversity with the one of the soil where black carbon was isolated. The structures of black carbon were separate physically from the soils and total genomic DNA was extracted and used as template in a PCR reaction, using primers of the 16S rRNA gene for the Bacteria Domain. The PCR product was used for construction of clone libraries and the clones were sequenced and compared with the 16S rRNA of RDPX database. The 16S rRNA gene clone libraries from the samples of pyrogenic black carbon, it shown that is a larger number of unknown bacteria in the black carbon than in the soil where it was isolated. Acidobacteria was the predominant phylum in the pyrogenic black carbon libraries from the both studied places, as well as in the soil library from Mina I site. However in the library Lagoa Balbina site there was predominance of the phylum Firmicutes. Through the rarefaction method it was possible to verify a smaller richness of OTUs in the bacterial communities presents in the pyrogenic black carbon structures when compared to the OTUs richness of the bacterial soil communities.But, when the OTUs richness is compared among the isolated structures of pyrogenic black carbon of the two places, it is observed that the richness is higher in the Mina I site. The values from diversity indexes revealed smaller diversity of OTUs in the pyrogenic black carbon libraries when compared with the soil libraries for the two studied areas. The obtained values with the nonparametric methods revealed larger OTUs richness in the black carbon library of Mina I site and in the ADE soil library of the Balbina site. The PCA analysis showed that the libraries of the site Balbina site were highly similar. In addition, the analysis with S-Libshuff verified that all of the compared libraries were significantly different in bacterial communities composition. The pyrogenic black carbon is not an inert structure, once it is capable of being inhabited by different bacteria, and its bacterial community structure is different from that one where is was segregated

Texte intégralRésumé :
String theory is a unified framework for general relativity and quantum mechanics, thus being a theory of quantum gravity. In this thesis we discuss various aspects of quantum gravity for particular systems, having in common the existence of horizons. The main motivation is that one major challenge in theoretical physics today is in trying to understanding how time dependent backgrounds, with its resulting horizons and space-like singularities, should be described in a controlled way. One such system of particular importance is our own universe.
We begin by discussing the information puzzle in de Sitter space and consequences thereof. A typical time-scale is encountered, which we interpreted as setting the thermalization time for the system. Then the question of closed time-like curves is discussed in the combined setting where we have a rotating black hole in a Gödel-like universe. This gives a unified picture of what previously was considered as independent systems. The last three projects concerns $c=1$ matrix models and their applications. First in relation to the RR-charged two dimensional type 0A black hole. We calculate the ground state energy on both sides of the duality and find a perfect agreement. Finally, we relate the 0A model at self-dual radius to the topological string on the conifold. We find that an intriguing factorization of the theory previously observed for the topological string is also present in the 0A matrix model.

Texte intégralRésumé :
Closed-loop system identification and fault detection and isolation are the two fundamental building blocks of process monitoring. Efficient and accurate process monitoring increases plant availability and utilisation. This dissertation investigates a subspace system identification and fault detection methodology for the Benfield process, used by Sasol, Synfuels in Secunda, South Africa, to remove CO2 from CO2-rich tail gas. Subspace identification methods originated between system theory, geometry and numerical linear algebra which makes it a computationally efficient tool to estimate system parameters. Subspace identification methods are classified as Black-Box identification techniques, where it does not rely on a-priori process information and estimates the process model structure and order automatically. Typical subspace identification algorithms use non-parsimonious model formulation, with extra terms in the model that appear to be non-causal (stochastic noise components). These extra terms are included to conveniently perform subspace projection, but are the cause for inflated variance in the estimates, and partially responsible for the loss of closed-loop identifiably. The subspace identification methodology proposed in this dissertation incorporates two successive LQ decompositions to remove stochastic components and obtain state-space models of the plant respectively. The stability of the identified plant is further guaranteed by using the shift invariant property of the extended observability matrix by appending the shifted extended observability matrix by a block of zeros. It is shown that the spectral radius of the identified system matrices all lies within a unit boundary, when the system matrices are derived from the newly appended extended observability matrix. The proposed subspace identification methodology is validated and verified by re-identifying the Benfield process operating in closed-loop, with an RMPCT controller, using measured closed-loop process data. Models that have been identified from data measured from the Benfield process operating in closed-loop with an RMPCT controller produced validation data fits of 65% and higher. From residual analysis results, it was concluded that the proposed subspace identification method produce models that are accurate in predicting future outputs and represent a wide variety of process inputs. A parametric fault detection methodology is proposed that monitors the estimated system parameters as identified from the subspace identification methodology. The fault detection methodology is based on the monitoring of parameter discrepancies, where sporadic parameter deviations will be detected as faults. Extended Kalman filter theory is implemented to estimate system parameters, instead of system states, as new process data becomes readily available. The extended Kalman filter needs accurate initial parameter estimates and is thus periodically updated by the subspace identification methodology, as a new set of more accurate parameters have been identified. The proposed fault detection methodology is validated and verified by monitoring process behaviour of the Benfield process. Faults that were monitored for, and detected include foaming, flooding and sensor faults. Initial process parameters as identified from the subspace method can be tracked efficiently by using an extended Kalman filter. This enables the fault detection methodology to identify process parameter deviations, with a process parameter deviation sensitivity of 2% or higher. This means that a 2% parameter deviation will be detected which greatly enhances the fault detection efficiency and sensitivity.Dissertation (MEng)--University of Pretoria, 2008.

Dissertação de Mestrado Integrado em Medicina VeterináriaEsta dissertação teve como objetivo principal caracterizar a fauna de simbiontes de chimpanzés (Pan troglodytes), e colobos pretos e brancos (Colobus sp.) de diferentes localidades Africanas (Parque Nacional de Sapo, na Libéria e em Bulindi, no Uganda), comparar resultados entre eles e estudos prévios e teorizar sobre as possíveis implicações zoonóticas dos simbiontes encontrados. Recorrendo a técnicas de coprologia como sedimentação MIF modificada e a flutuação de Sheather, e um teste de imunofluorescência direta para deteção de oocistos de Crypstosporidium e cistos de Giardia, 47 amostras fecais preservadas de chimpanzé e 15 de colobos pretos e brancos foram examinadas. Os protozoários detetados incluíram Troglodytella abrassarti, Entamoeba spp., Blastocystis sp. e Iodamoeba buetschlii; e nematodes, Trichuris sp, Colobenterobius sp., strongylideos e várias larvas de nematodes. Todas as amostras foram negativas no teste de imunofluorescência directa. Em geral, o espectro de simbiontes encontrado no presente estudo está de acordo com o que é regularmente descrito em estudos que abordam chimpanzés e colobos pretos e brancos de vida selvagem. Contudo, pequenos microrganismos aquáticos denominados Rotifera ou rotíferos foram observados pela primeira vez em amostras fecais de chimpanzé e colobos pretos e brancos. Considerando o contato próximo entre os primatas estudados e seres humanos, é importante realizar futuras pesquisas recorrendo a técnicas moleculares nos simbiontes assinalados por este trabalho e avaliar o seu real potencial zoonótico.
ABSTRACT - Gastrointestinal symbionts of wild chimpanzees and sympatric colobus monkeys living in close proximity of humans in Liberia and Uganda - This dissertation aimed to characterize the symbiont fauna of chimpanzees (Pan troglodytes) and black and white colobus (Colobus sp.) from different African localities, (Sapo National Park in Liberia and Bulindi in Uganda), compare results between them and previous studies, and theorize about possible zoonotic implications of the found symbionts. Using coprologic techniques as modified MIF sedimentation and Sheather’s flotation, and a direct immunofluorescence teste for detection of Crypstosporidium oocysts and Giardia cysts, 47 chimpanzee and 15 black and white colobus preserved fecal samples were examined. Detected protozoans included Troglodytella abrassarti, Entamoeba spp., Blastocystis sp. and Iodamoeba buetschlii; and nematodes, Trichuris sp., Colobenterobius sp., strongylids and various nematodes larvae. All samples were negative for the direct immunofluorescence test. Overall, the spectrum of symbionts found in the present study is in accordance with what is regularly described in studies addressing the free ranging chimpanzees and black and white colobus. However, small aquatic microorganisms denominated Rotifera or rotifers were observed for the first time in chimpanzee and in black and white colobus faecal samples. Considering the close contact between the studied primates and humans, it is important to conduct further research using molecular techniques in the found symbionts to assess the real zoonotic potential.

Texte intégralRésumé :
Abstract The aim of this essay is to explain why Caryl Phillips presents Joyce as "the adopted daughter of Africa" at the end of Crossing the River (1993). This will be done by performing a close reading. This essay will focus on Joyce’s actions and behaviour. Aspects of feminism and postcolonial theory will act as the theoretic basis for the analysis. The analysis of Joyce’s character will be put in relation to the whole of Phillips’ “Black Atlantic” narrative and to gender and third wave feminist theories. The analysis will show that Joyce, by breaking racial norms, renouncing her faith, defying her mother, divorcing her husband, and falling in love with Travis, is the person who defines hope in the novel. Her character, together with her son Greer, shows a path to reconciliation between races in the aftermath of colonialism.

Texte intégralRésumé :
As a society, America has struggled to resolve some deep-seated differences over values. These differences are most visible and divisive in the historical White-Black dichotomy. In the realm of education, the Black male achievement gap is a vivid reminder of this previously legalized oppressor-oppressed relationship.
The Black male achievement gap is a particularly unique phenomenon in that Black male students surpass every other racial and gender category in educational achievement gaps (NCES, 2013a, 2013b, 2014a, 2014b; NAEP, 2011, 2013). This phenomenon is well-known and well researched. Many researchers point to a fundamental conflict over values that results in this lingering gap between Black male students and their peers. Though these value differences have been researched, how these differences are being reconciled in efforts to close Black male achievement gaps is not known.
Argyris and Schön’s (1978, 1989b) theoretical framework provides a practical way to engage the values of the school organization. This perspective allows social scientists to understand whether or not the values guiding the actions of the organization are enabling the organization to effectively meet its stated goals. This research study analyzes a school’s process of responding to the Black male achievement gap, focusing on the school leader’s efforts to close these gaps. The theory of action framework allows the school leader’s efforts to be mapped, distinguishing between espoused and in-use theories of action and understanding if and how the in-use theories are reconciling value differences within the school organization.

Texte intégralRésumé :
U radu je ispitan uticaj vodnog deficita na fiziološke osobine klonova crne topole ipopulacija hrasta lužnjaka i cera, kao i mogućnost oporavka ovih biljaka nakon ponovnog uspostavljanja optimalnog vodnog režima. Cilj istraživanja je bio da se ukaže na potencijal ispitivanih genotipova topole i hrastova za opstanak u promenljivim uslovima životne sredine, u skladu sa aktuelnim klimatskim promenama koje uključuju smanjenje količine padavina i ograničenu dostupnost vode. Dobijeni rezultati su pokazali specifično variranje ispitivanih morfo-anatomskih, fizioloških i biohemijskih parametara koje je zavisilo od momentalne vlažnosti zemljišta na primenjenom tretmanu (kontrola, suša praćena oporavkom, konstantna suša) i od genotipa biljke. Negativan uticaj vodnog deficita na tretmanu konstantne suše je u najmanjoj meri bio ispoljen na rastenje klona topole X/32, populaciju hrasta lužnjaka L1 i populaciju hrasta cera C1. Indeks tolerancije na stres izračunat na osnovu visine biljke (PHSI) takodje je potvrdio dobru morfološku prilagodjenost pomenutih genotipovana uslove suše. Dobijene vrednosti indeksa stoma ukazuju da vodni status ispitivanih populacija hrastova nije bio naroĉito pogodjen vodnim deficitom na sušnim tretmanima. Tretman konstantne suše je u oba ogleda doveo do najvećeg smanjenja vrednostiparametara razmene gasova kod skoro svih genotipova. S druge strane, primenjeni sušni tretmani nisu uslovili smanjenje sadržaja fotosintetiĉkih pigmenata, kao ni parametra Fv/Fm, kod većine ispitivanih biljaka. U odnosu na kontrolu, sadržaj prolina u listovima ispitivanih biljaka na tretmanu konstantne suše bio je znaĉajno povećan, a aktivnost enzima nitrat-reduktaze značajno smanjena, kod većine genotipova. Genotipovi kod kojih u uslovima jakog vodnog deficita nije došlo do značajne promene većine ispitivanih morfo-anatomskih, fizioloških i biohemijskih parametara mogu biti od velike važnosti kad je u pitanju njihov odabir i upotreba za uspešno pošumljavanje sušnih staništa, kojih će biti sve više usled negativnog uticaja brojnih ekoloških činilaca nastalih kao posledica klimatskih promena.The impact of water deficit and recovery on physiological features of the black poplar clones, as well as of the oaks populations were analyzed. The aim of this research was to indicate the potential of the studied genotypes for survival under changing environmental conditions, in accordance with current climate changes, which include the reduction in amount of rainfall and limited water availability. Obtained results have shown a specific variation of studied morpho-anatomical, physiological and biochemical parameters which depended on soil humidity on the applied treatment (control, drought followed by recovery and permanent drought), as well as on plant genotype.Water deficit on permanent drought treatment had little negative effect on plant growth of poplar clone X/32, as well as oak populations L1 and C1. Plant height stress tolerance index also confirmed good morphological adaptation to drought of these genotypes. Stomatal index was not negatively affected by water deficit in oak plants. In both experiments, a permanent drought treatment led to the largest reduction in the values of gas exchange parameters in almost all genotypes.On the other hand, concentration of photosynthetic pigments was not considerably decreased in plants exposed to water deficit, as well as the parameter Fv/Fm, in most examined plants. Compared to the control, the impact of permanent drought treatment on biochemical parameters was expected, in the most cases. Compared to the control, proline content in leaves of most examined genotypes was significantly increased on permanent drought treatment, while nitrate reductase activity was significantly decreased.Examined genotypes exhibiting slight or no reduction in values of the most examined parameters during severe drought stress, could be used for afforestation in arid sites. Arid habitats appeared to be more numerous due to the effects of global climate changes.

Texte intégralRésumé :
Konsequent betriebener Leichtbau führte und führt weiterhin zu steigender Komplexität in der Blechumformung. Erkenntnisse aus Forschungsaktivitäten zur gezielten Beeinflussung, Regelung und Vollautomatisierung des Tiefziehprozesses konnten jedoch bisher nicht in Großserienpresswerke transferiert werden. Aus diesem Grund wird in dieser Arbeit ein Werkzeugkonzept vorgestellt, welches unter Berücksichtigung der relevanten Randbedingungen eine gezielte lokale Beeinflussung des Umformprozesses ermöglicht. Gleichzeitig gestattet es, mit Hilfe eines neuartigen, optischen Sensorkonzeptes die Geschwindigkeit sowie den Einlaufweg der Platine zu überwachen. Es wird eine methodische Vorgehensweise zur Herstellung von Umformwerkzeugen, auf der neuen Konzeption basierend, beschrieben. Umformsimulationen dienen dabei zur Identifikation von kritischen Bauteilen und deren neuralgischen Zonen. Eine entsprechend angepasste Konstruktion bietet Bauraum für die Implementierung von zusätzlichen Aktuatoren und einem definiert elastischen Einsatz. Abschließende FEM-Analysen mit Volumenmodellen sowie die Kalkulation der Lebensdauer bestätigen eine ausreichende Flexibilität und die erforderliche Dauerfestigkeit. Im Rahmen der experimentellen Analyse konnte eine drastische Verkürzung der Anlaufzeit durch deutlich reduzierten Tuschieraufwand aufgrund der Anpassungsfähigkeit sowie Flexibilität des definiert elastischen Werkzeugkonzeptes nachgewiesen werden. Neben diesem Potential hinsichtlich strukturierter Inbetriebnahmen ermöglicht die Konzeption eine Kompensation von Pressenunterschieden und individuellen Maschinencharakteristika (wie bspw. Stößelverkippungen) wodurch der Transfer von der Einarbeitspresse auf die Produktionsanlage wesentlich weniger Korrekturschleifen hervorruft. Außerdem werden der Qualitätsaufwand (Nachtuschieren) während der laufenden Serienproduktion, Stillstandszeiten und Ausschussquoten stark verringert. Darüber hinaus ergeben sich erweiterte Anwendungsmöglichkeiten bei der Umformung von tailored blanks und aus der Minimierung/Optimierung des Platinenzuschnittes enorme Einsparungs- und Kostenpotentiale. Abschließend werden die Vorteile eines geschlossenen Prozessregelkreises durch die Verknüpfung von Sensorik und Aktorik analysiert. Dabei bestätigt das vorgeschlagene Regelkonzept einer Prozessnachführung die Erhöhung der Prozessstabilität bei schwankenden Prozessparametern durch die gezielte, lokale Verteilung der Flächenpressung. Zuletzt diskutiert der vorliegende Beitrag Transfermöglichkeiten der Verbesserungspotentiale in kommende Serienwerkzeuge vor dem Hintergrund von Kostenrestriktionen und Minimierung des bedientechnischen sowie konstruktiven Aufwandes.

The topic of my master´s thesis was to create an architectural study of the Fakulty of Fine Arts in Brno - city part Veveří. The site lies near the Faculty of Law of Masaryk University and it´s bordered by streets Šumavská, Veveří, Bulínova and Akademická. The project ties together the architectural study from subject TG02 witch solved the second part of the programme "Academic Square" and it was a construction of the fakulty of Forensic Engineering and the background for both faculties. So the solution is a compex architectural study which sorts the urban and also the architectural aspects of both faculties and their background. The main idea of the urban concept is to také up the surrounding bulit-up-area which is typical for this part of Brno. The philosophy of the architectural solution comes from the concept of the traditional British universities. So the solution are two objects of the faculties with plane shape od the letter U which clutches the volume of the common background between each other.

L’esercito italiano e la conquista della Catalogna (1808-1811)
Uno studio di Military Effectiveness nell’Europa napoleonica
Settori scientifico-disciplinari SPS/03 – M-STO/02
La ricerca ha lo scopo di ricostruire e valutare l’effettività militare dell’esercito italiano al servizio di Napoleone I. In primo luogo attraverso un’analisi statistica e strategica della costruzione, e del successivo impiego, dell’istituzione militare del Regno d’Italia durante gli anni della sua esistenza (1805-14); successivamente, è stato scelto un caso di studi particolarmente significativo, come la campagna di Catalogna (1808-11, nel contesto della guerra di Indipendenza spagnola), per poter valutare il contributo operazionale e tattico dei corpi inviati dal governo di Milano e la loro integrazione con l’apparato militare complessivo del Primo Impero.
La tesi ha voluto rispondere alla mancanza di studi sul comportamento in guerra dell’esercito italiano e, allo stesso tempo, introdurre nella storiografia militare italiana la metodologia di studi, d’origine anglosassone e ormai di tradizione trentennale, di Military Effectiveness.
La ricerca si è primariamente basata, oltre che sulla copiosa memorialistica a stampa italiana e francese, sulla documentazione d’archivio della Secrétairerie d’état impériale (Archives Nationales di Pierrefitte-sur-Seine, Parigi), del Ministère de la Guerre francese (Service historique de la Défence, di Vincennes, Parigi) e del Ministero della Guerra del Regno d’Italia (Archivio di Stato di Milano).
Dal punto di vista dei risultati è stato possibile verificare come l’esercito italiano abbia rappresentato, per Bonaparte, uno strumento duttile e di facile impiego, pur in un contesto di sostanziale marginalità numerica complessiva di fronte alle altre (e cospicue) forze messe in campo da parte dell’Impero e dei suoi altri Stati satellite e alleati. Per quanto riguarda la campagna di conquista della Catalogna è stato invece possibile appurare il fondamentale contributo dato dal contingente italiano, sotto i punti di vista operazionale e tattico, per la buona riuscita dell’invasione; questo primariamente grazie alle elevate caratteristiche generali mostrate dallo stesso, ma anche per peculiarità disciplinari e organizzative che resero i corpi italiani adatti a operazioni particolarmente aggressive.The Italian Army and the Conquest of Catalonia (1808-1811) A Study of Military Effectiveness in Napoleonic Europe Academic Fields and Disciplines SPS/03 – M-STO/02 The research has the purpose of reconstruct and evaluate the military effectiveness of the Italian Army existed under the reign of Napoleon I. Firstly through a statistic and strategic analysis of the development, and the following deployment, of the military institution of the Kingdom of Italy in the years of its existence (1805-14). Afterwards, a particularly significant case study was chosen, as the campaign of Catalonia (1808-11, in the context of the Peninsular War), in order to assess the operational and tactical contribution of the regiments sent by the Government of Milan and their integration in the overall military apparatus of the First Empire. The thesis wanted to respond to the lack of studies on the Italian army’s behavior in war and, at the same time, to introduce the methodology of the Military Effectiveness Studies (of British and American origin and, by now, enriched by a thirty-year old tradition) in the Italian historiography. The research is primarily based, besides the numerous memoirs of the Italian and French veterans, on the archive documentation of the Secrétairerie d’état impériale (Archives Nationales of Pierrefitte-sur-Seine, Paris), of the French Ministère de la Guerre (Service historique de la Défence, of Vincennes, Paris) and of the Italian Ministero della Guerra (Archivio di Stato di Milano). About the results, it has been verified how the Italian army has become a flexible and suitable instrument for Bonaparte, albeit in a context of substantial overall numerical marginality in comparison to the heterogeneous forces available to the Empire and its others satellites and allied states. Regarding the campaign of Catalonia, instead, it was possible to ascertain the fundamental contribution of the Italian regiments, in an operational and tactical perspective, for the success of the invasion. This was primarily due to the excellent general characteristics shown by the expeditionary force, but also to disciplinary and organizational peculiarities that have made the Italian corps suitable for particularly aggressive operations.

The collision of two black holes is of great important as the most interesting source of gravitational wave .In the coming years, we expect the LIGO and VIRGO detectors to start. operations. Then we can get more precise information on the properties of the gravitational wave. In this paper, we study the problem of the evolution of the Misner solution .It is the initial condition of the collision of two black holes with zero velocity and zero angular velocity. When the two black holes are very close, we use the perturbation method to get the equations of time evolution. Then we solve these equations using numerical computation. From the result of the computation, we can obtain the properties of generation of the gravitational wave produced. So, the study of the close approximation of the collision of two black holes indeed offers us a deeper understanding of the generation of the gravitational wave.

Texte intégralRésumé :
A research report submitted to the Faculty of Humanities, University of the Witwatersrand, Johannesburg, in partial fulfilment of the requirements for the degree Master of Arts in Social
& Psychological Research 2017.The aim of this study was to enquire on the narratives of black gay South African university students who are ‘in the closet" i.e. their parents do not know about their sexuality only a few trusted friends within the university space. These narratives focused on their social and sexual experiences which involved their interactions within the university as black gay men in the closet. Four black gay students from two Johannesburg universities aged 21 to 24 participated in this study. The study made use of a qualitative research design grounded in Narrative Theory. Unstructured interviews were conducted and the collected narratives were analysed using Narrative Analysis. Each participant narrated different individual experiences of the university space as well as how they negotiated their sexual practices as gay men who are in the closet. The participants offered knowledge about the university spaces that they occupied as well as the communities in which they were raised. The participants" narratives highlight the intersectional challenges black gay men from township and rural South Africa endure because of social constructs of heteronormativity, hegemonic masculinity, religious intolerance and homophobia, all which were perpetuated within these spaces. These challenges also affected their sexual experiences; influencing their lack of interest in sexual intercourse. The study highlights the importance of creating safe spaces for gay people to express their sexuality visibly. The study argues that visibility can challenge social ills experienced by gay people within university spaces and the country at large.

Texte intégralRésumé :
This thesis is an integrated study that links several disciplines-archaeology,
anthropology, geography, atmospheric sciences, and
microbiology. It attempts to generate an argument that central to climate
change is disequilibrium in human ecologies- in my case, disease ecologies
in Iceland during the 15th century.
This thesis investigates the environment's effect on human adaptability.
The effect of the environment on Icelanders as they moved from settlement to
later periods was disquieting. The climate of the world was changing- moving
from the Medieval Warm Period to the colder Little Ice Age.
I analyze the disease ecology of the 15th century and also conduct an
archeological and cultural analysis of the Icelandic people, to show the
deficiencies in their adaptation, and submit that certain shortcomings in their
physical environment, as well as the inadequate adaptive synthesis to the
environment, led to a marginal adaptation. This was augmented by political
unrest and problems with outside trade, which left them vulnerable and
susceptible to disease pathogenesis.
I discuss the climate change during the Little Ice Age, and assert that
this event is the crucible that crushed Iceland after 400 years of reasonably
good fortune. Hundreds of epidemics, natural disasters, and hardships befall
the Icelanders. One of them is the plague, which comes twice in the 15th
century. The important observation here is that the epidemiological and
archeological evidence does not always match up. The principal problem is
that the traditional vector for the disease cannot have survived the climate as
it was in the winters during the LIA. I offer an analysis that pontificates this
issue and I examine the ongoing debate concerning The Black Death in
Europe.
I introduce another possible explanation: the introduction of disease
through environmental vectors. The creation of disease ecologies through
climate change is important, in light of problems that we face today. I discuss
the phenomenon of the dust storm and its connection to disease
pathogenesis.
By showing several key examples of dust from Africa to disease
pathogenesis in the Caribbean, I make the connection a good one. In addition
to this connection is the atmospheric analysis that shows incontrovertibly that
the dust found in Greenland ice cores is only from Asia. Finally, there is the
fact that the inveterate loci of the plague bacterium is located in the same
areas that Asian Dust Events occur and travel from.
I create a methodology for investigating this disease ecology and am
able to show that the pathogen can be identified in situ- meaning that it can
be found in geological deposits that can be properly dated. My pilot study
creates a methodology for the examination of ice cores- the principal reservoir
for atmospheric deposits made during the LIA.
Finally, I look at the aftermath. I introduce the idea of disease ecology,
as opposed to that of a healthy ecology, and suggest by the end of the thesis
that within the disease ecology are created many of the platforms for
emergent biological changes that translate through evolution over time.
Like the bacterium in the ice core, I suggest that evidence for disease
states in the history of a people can be found through laboratory techniques.
The presence of the CCR5 gene mutation is indicative of such a presence. I
believe that the presence of the delta 32 gene mutation found in Icelandic
people is the result of being exposed to the plague in the 15th century.
This thesis is a platform for future synoptic scale disease studies.Graduation date: 2005

After the implementation of English education in Taiwan for decades, the bimodal distribution of students’ English abilities obviously appears in the achievement tests of all stages. The urban-rural gap and family background are the main causes of this phenomenon. If students at elementary stage make little proficiency in English or even lose interest in learning it, English teachers will face great difficulties in teaching them after they enter junior high school. To improve the bimodal distribution of students’ English abilities and leave no child behind, the remedial instruction will play an important role in English language teaching. This study aims to conduct the cognitive diagnostic analysis of learning path based on the Rule-Space Model, proposed by Tasuoka in 1983. The subjects of this study were the seventh-grade students from two classes of a junior high school in Miaoli County. It tries to explore the mastery level of students’ potential knowledge attributes, to figure out the factors that influence students’ achievement and to provide them with appropriate remedial instruction. The experimental results are listed as follows: 1.The Students had significant progress in the post-test after receiving adaptive diagnostic suggestions and appropriate remedial instruction. 2.The Students in the experimental group could correspond to 8 kinds of attribute combinations from the target unit of this study. 3.According to the mastery level of students’ potential knowledge attributes, 10 kinds of knowledge states could be classified and two learning paths could be identified. 4.On the basis of the the students’percentage of knowledge states, experimental group students’ learning path is likely to be the path 1.

Texte intégralRésumé :
In this thesis I present three separate studies on three different topics in General Relativity.
The first study investigates the accuracy with which the mass and angular momentum of a black hole can be determined by measurements of gravitational waves from the hole, using a laser-interferometer gravitational-wave detector. The black hole is assumed to have been strongly perturbed, perhaps by coalescence with a binary companion, and the detector measures the waves produced by its resulting vibration and ring-down. The uncertainties in the measured mass and angular momentum arise from the unavoidable presence of noise in the detector. It is found that the faster the hole rotates, the more accurate the measurements will be, with the uncertainty in the angular momentum decreasing rapidly with increasing rotation speed. It is also found that the errors in the mass and angular momentum are highly correlated.
The second study is an analysis of the gravitational collapse of an infinitely long, cylindrical dust shell. This analysis is expected to be helpful in understanding the behavior during collapse of more realistic, finite-length bodies. It is found that the collapse evolves into a naked singularity in finite time, as measured by a distant observer or by one riding on the shell. Analytical expressions for the variables describing the collapse are found at late times, near the singularity. The picture is completed with a numerical simulation that follows the collapse from the start until very close to the singularity. The singularity is found to be strong, in the sense that an observer riding on the shell will be infinitely stretched in the direction parallel to the symmetry axis, and infinitely compressed in the azimuthal direction. The gravitational waves emitted from the collapse are also analyzed.
The last study focuses on a different kind of phenomenon, namely, the consequences of the existence of closed timelike curves in a spacetime that contains a wormhole. One might expect that the closed timelike curves would cause difficulty for the initial value problem for systems that evolve in such a spacetime: a system with apparently well-posed initial conditions might have no self-consistent solutions to its evolution equations. We study the simple case of a macroscopic, classical particle with a hard-sphere potential (a "billiard ball"), and we focus attention on initial conditions for which the evolution, if followed naively, is self- inconsistent: the ball enters one mouth of the wormhole and then comes out of the other mouth at an earlier time, then collides with its younger self, preventing itself from ever entering the first mouth. We find, surprisingly, that for all such "dangerous" initial conditions, there are an infinite number of self-consistent evolutionary solutions, involving a glancing collision and any number of wormhole traversals. We also find that for many non-dangerous initial conditions, there also exist an infinity of possible evolutions.
