Abstract:
Cette thèse est composée de deux parties. La première concerne les échantillonneurs dits de Monte-Carlo séquentiel (les échantillonneurs SMC). Il s'agit d'une famille d'algorithmes pour produire des échantillons venant d'une suite de distributions, grâce à une combinaison de l'échantillonnage pondéré et la méthode de Monte-Carlo par chaîne de Markov (MCMC). Nous proposons une version améliorée qui exploite les particules intermédiaires engendrées par l'application de plusieurs pas de MCMC. Elle a une meilleure performance, est plus robuste et permet la construction d'estimateurs de la variance. La deuxième partie analyse des algorithmes de lissage existants et en propose des nouveaux pour les modèles espace-état. Le lissage étant coûteux en temps de calcul, l'échantillonnage par rejet a été proposé dans la littérature comme une solution. Cependant, nous démontrons que son temps d'exécution est très variable. Nous développons des algorithmes ayant des coûts de calcul plus stables et ainsi plus adaptés aux architectures parallèles. Notre cadre peut aussi traiter des modèles dont la densité de transition n'est pas calculable
This thesis is composed of two parts. The first part focuses on Sequential Monte Carlo samplers, a family of algorithms to sample from a sequence of distributions using a combination of importance sampling and Markov chain Monte Carlo (MCMC). We propose an improved version of these samplers which exploits intermediate particles created by the application of multiple MCMC steps. The resulting algorithm has a better performance, is more robust and comes with variance estimators. The second part analyses existing and develops new smoothing algorithms in the context of state space models. Smoothing is a computationally intensive task. While rejection sampling has been proposed as a solution, we prove that it has a highly variable execution time. We develop algorithms which have a more stable computational cost and thus are more suitable for parallel environments. We also extend our framework to handle models with intractable transition densities

APA, Harvard, Vancouver, ISO, and other styles
Abstract:
Many large carnivores are declining globally; most threatened or risk extinction due to a loss of habitat, resources, and direct removal; often the later as a result of conflict with humans. Although leopards and many meso-carnivore species are still free roaming in South Africa, few data are available on these species outside large protected areas as they are often elusive, wide ranging and found at low densities. More data are needed on the population dynamics, ecology and biology of species such as leopard, if we are to implement evidence-based approaches to their conservation within small reserves and surrounding unprotected areas. Camera traps are being increasingly utilized in research, as they can record data on a species or a whole community at relatively low cost. Here we used a network of camera traps to monitor species presence at Thaba Tholo Wilderness Reserve, Mpumalanga, South Africa. We found that camera trap efficacy varied between species, with smaller carnivores significantly under-recorded more frequently than larger predators. However, leopards were successfully captured by camera trap when compared with more traditional monitoring methods (i.e. spoor). Small reserves may play an important role in the conservation of carnivores, but often these reserves are surrounded by farmland and the successful separation of livestock and game using a fence can affect vegetation composition, fragmenting the land further. However, these effects may be limited by the free movement of wild browsers and grazers through holes in the fence which may also decrease the negative effects of fencing while supporting endangered and highly mobile species such as the leopard Panthera pardus. Leopard densities were found to be 3.04 (S.E. +/-1.55) to 4.97 (S.E. +/-2.14) leopards per 100km2, which was lower than other estimates from South Africa, however the population was stable throughout the study suggesting the reserve was a source for leopard and offspring were dispersing. Although there was no evidence of habitat preference by the leopard, habitat was found to be more significant in influencing relative local abundances of meso-carnivores than potential associations with leopard and other larger carnivores. However abundance may have been affected by factors outside the reserve as conflict with humans was evident. Negative actions towards leopard and other carnivores in retaliation to the predation of animal stock occurred in the farmland surrounding the study site, with a significantly higher percentage of commercial game farmers responding that they would take action against one or more species of carnivore compared to livestock owners. The financial loss sustained with increasing game prices in South Africa could therefore increase the conflict between humans and carnivores across the country, which in turn could have detrimental effects on local leopard and other carnivore populations. The relatively high numbers of the extremely rare erythristic leopard occurring within the relatively low density leopard population is likely to be the result of genetic drift, which may have been a result of this conflict; highlighting that although small reserves may play an important role in the protection and propagation of threatened species it is human acceptance of carnivores which is likely to be vital in the successful conservation and long term survival of predators outside protected areas.

Abstract:
This thesis examines the life and ministry of William Van Mildert (I765-I836) and his membership of the early nineteenth century High Church group known as the Hackney Phalanx. It considers Van Mildert's experiences before ordination and as deacon, priest and bishop, and their influence on his conception of the nature and mission of the Church of England. It relates the measures initiated by the Phalanx for reforming and extending the work of the Church to its members' understanding of their social and political context, and indicates some features of their shared theological position, particularly their ecclesiology. Among the undertakings of the Phalanx, the restructuring of the S.P.C.K, and the founding of new Church Societies to promote education and church-building receive particular attention. Van Mildert's labours as a member of the House of Lords are considered in detail, especially during his Durham episcopate (1826-36), when he was prominent in the unsuccessful opposition to Roman Catholic emancipation and to the Church Temporalities (Ireland) Act of 1833.The founding of Durham University owed much to Van Mildert, Besides contributing an estimated £10,000, he was closely involved both in developing the plans and in piloting the necessary legislation through Parliament. Van Mildert's theological writings are more notable for their extensive acquaintance with the work of earlier theologians than for originality: he disliked Innovation in matters of religion. Besides sermons and episcopal charges, he published Boyle Lectures taking a systematic view of the rise and progress of Infidelity and (while Oxford Regius Professor of Divinity) Bampton Lectures on the principles of Scripture-interpretation. He also produced a complete edition of the works of Waterland. Cited as a theological authority by the Oxford Movement, he nevertheless held aloof from the Movement’s beginnings.

Dunbar, Jill. "The efficacy of a seizure assessment risk tool in predicting occurrence of tonic-clonic seizures." Thesis, University of Glasgow, 2015. http://theses.gla.ac.uk/6840/.

Full text
APA, Harvard, Vancouver, ISO, and other styles
Abstract:
Background: Previous research has identified that the occurrence of a Global Tonic Clonic Seizure (GTCS) is a high risk factor for serious injury or death within the epilepsy population. Fast intervention during a GTCS accompanied by EEG suppression is needed to reduce the risk of serious injury or death. Research has suggested that intervention should optimally occur within 50 seconds of EEG suppression commencing. Identifying patients who are at greatest risk of GTCS could enable targeted monitoring of patients and facilitate quicker intervention. However, at this time there are no specific guidelines for risk assessment in regards to risk of GTCS. The William Quarrier’s Scottish Epilepsy Centre (SEC) developed a Seizure Assessment Risk Score (SARS) tool for use in Video Telemetry (VT) epilepsy units based on risk factors highlighted by previous research. The SARS was implemented with all new admissions to the SEC and data was collected on seizure activity through routine clinical practice. Aim: The aim of this study was to investigate the efficacy of the SARS tool at predicting the occurrence of GTCS activity in patients admitted to the SEC. Methods: Seizure activity data and daily SARS scores were collected from 37 patients admitted to the SEC over an 8 month period. The data were then explored to determine if there was a predictive relationship between higher SARS scores and GTCS occurrence. Results: Data from 37 patients indicated that there was no significant relationship between higher scores on the SARS and the incidence of GTCS. The current SARS tool does not appear to adequately differentiate between those patients who do experience a GTCS during their admission to the VT unit and those who do not. Conclusion: The study highlights that the SARS tool requires further development to ensure that patients are adequately assessed for risk of experiencing a GTCS. While the majority of the sample was rated ‘high risk’ according to the SARS tool, the incidence of GTCS was in fact relatively low. The study also discusses the difficulties surrounding risk assessing an already specialised and clinically risky population.

Abstract:
Alexithymia refers to difficulties in recognizing one’s own emotions and others emotions. Theories of emotional embodiment suggest that, in order to understand other peoples’ feelings, observers re-experience, or simulate, the relevant component (i.e. somatic, motor, visceral) of emotion’s expressed by others in one’s self. In this way, the emotions are “embodied”. Critically, to date, there are no studies investigating the ability of alexithymic individuals in embodying the emotions conveyed by faces. In the present dissertation different implicit paradigms and techniques falling within the field of affective neuroscience have been employed in order to test a possible deficit in the embodiment of emotions in alexithymia while subjects were requested to observe faces manifesting different expression: fear, disgust, happiness and neutral. The level of the perceptual encoding of emotional faces and the embodiment of emotions in the somato-sensory and sensory-motor system have been investigated. Moreover, non-communicative motor reaction to emotional stimuli (i.e. visceral reactions) and interoceptive abilities of alexithymic subjects have been explored. The present dissertation provided convergent evidences in support of a deficit in the processing of fearful expression in subjects with high alexithymic personality traits. Indeed, the pattern of fear induced changes in the perceptual encoding, in the somato-sensory and in the somato-motor system (both the communicative and non communicative one) is widely and consistently altered in alexithymia. This support the hypothesis of a diminished responses to fearful stimuli in alexithymia. In addition, the overall results on happiness and disgust, although preliminary, provided interesting results. Indeed, the results on happiness revealed a defective perceptual encoding, coupled with a slight difficulty (i.e. delayed responses) at the level of the communicative somato-motor system, and the emotion of disgust has been found to be abnormally embodied at the level of the somato-sensory system.

Abstract:
Abstract Characterization of the transient rheological response of polymer melts is important for computerized modeling and optimization of the manufacturing processes involving fast polymer melt flow such as injection molding and extrusion. In this paper, a new cone-and-plate rheometer utilizing the Kolsky torsion bar technique is reported. This rheometer can be accelerated to an angular velocity of 1600 rad/s within 100 μs. It enables characterization of the transient response of polymer melts for shear rates up to 104 1/s, temperatures up to 300°C, pressures up to 10 MPa, and shear strains up to 1000%. Experimental data are presented for a low-density polyethylene melt at shear rates between 780 1/s and 6840 1/s. The results show that the shear stress in the material increases not only with the shear rate but also more significantly with the shear strain. The significance of this finding is also discussed.

Abstract:
Accurate simulation and understanding of gas turbine performance is very useful for gas turbine users. Such a simulation and performance analysis must start from a design point. When some of the engine component parameters for an existing engine are not available, they must be estimated in order that the performance analysis can be carried out. However, the initially simulated design point performance of the engine using estimated engine component parameters may give a result that is different from the actual measured performance. This difference may be reduced with better estimation of these unknown component parameters. However, this can become a difficult task for performance engineers, let alone those without enough engine performance knowledge and experience, when the number of design point component parameters and the number of measurable/target performance parameters become large. In this paper, a gas turbine design point performance adaptation approach has been developed to best estimate the unknown design point component parameters and match the available design point engine measurable/target performance. In the approach, the initially unknown component parameters may be compressor pressure ratios and efficiencies, turbine entry temperature, turbine efficiencies, air mass flow rate, cooling flows, by-pass ratio, etc. The engine target (measurable) performance parameters may be thrust and SFC for aero engines, shaft power and thermal efficiency for industrial engines, gas path pressures and temperatures, etc. To select initially the design point component parameters, a bar chart has been used to analyze the sensitivity of the engine target performance parameters to the design point component parameters. The developed adaptation approach has been applied to a design point performance matching problem of an industrial gas turbine engine GE LM2500+ operating in Manx Electricity Authority (MEA), UK. The application shows that the adaptation approach is very effective and fast to produce a set of design point component parameters of a model engine that matches the actual engine performance very well. Theoretically the developed techniques can be applied to other gas turbine engines.

Abstract:
This work supports new gas turbine designs for improved performance by evaluating the use of endwall contouring in a cascade that is representative of a first stage stator passage. Contouring accelerates the flow, reducing the thickness of the endwall inlet boundary layer to the turbine stage and reducing the strength of secondary flows within the passage. Reduction in secondary flows leads to less mixing in the endwall region. This allows improved cooling of the endwall and airfoil surfaces with injected and leakage flows. The present paper documents component misalignment and leakage flow effects on the aerodynamic losses within a passage having one contoured and one straight endwall. Steps on the endwall and leakage flows through the endwall can lead to thicker endwall boundary layers, stronger secondary flows and possibly additional vortex structures in the passage. The paper compares losses with steps of various geometries and leakage of various flow rates to assess their importance on aerodynamic losses in this contoured passage. In particular, features associated with the combustor-to-turbine transition piece and the slashface gap, a gap between two vane segments on the vane platform, are addressed. An n-factorial study is used to quantify the importance of such effects on aerodynamic losses.

Abstract:
A medium size gas turbine combustor of 1.5 MW of Delft University (TUD) has been tested to combust low calorific value (LCV) fuel gas. The LCV gas was obtained from pressurized gasification of wood pellets class A, miscanthus giganteus and brown coal and was cleaned from its particulates by high temperature ceramic filters of β-cordierite. Stable combustion of (biomass derived) low calorific value fuel gas with heating values (LHV) between 1.64 and 4.48 MJ/m3n (50 to 120 Btu/scf) was accomplished due to high fuel gas temperatures ranging from 845 to 1099 K. Main species (O2, CO2,) and minor species (Ar, CH4, H2, CO, NO) were measured in the exhaust and by a traversing probe after the primary zone of the combustor. The water and nitrogen contents in the exhaust were calculated from the element balances. The results are compared with a previously tested combustor of ALSTOM Power of the RQL type.

Abstract:
Aviation fuel is a petroleum product that fulfills the Standard Specification for Aviation Turbine Fuels. Crude oil has been the raw material for production of aviation fuels for many years. Since the availability of crude oil is predicted to be limited in the future, alternative raw materials for aviation fuels are highly desirable. A Swedish company, Oroboros AB, has developed a novel clean synthetic jet fuel, LeanJet®. The fuel is produced synthetically from synthesis gas (Syngas) by the Fischer-Tropsch process. A comparative experimental investigation of combustion properties has been performed, comparing the synthetic jet fuel with Jet A1. The following parameters were investigated in an atmospheric combustor, which was originally designed for a Volvo Aero turbine (VT40): • Emissions of NOx, CO and HC; • Ignition and extinction points; • Liner temperatures; • Soot levels in the combustor. The emission measurements showed good combustion efficiency with low HC and CO for both fuels. With very lean mixtures, however, both the CO and the HC levels increased for the synthetic fuel. The nitrous oxides for the synthetic jet fuel were reduced over the operation conditions investigated. Qualitative reduction of soot levels was also seen for the synthetic jet fuel. The fuels showed no difference in material temperature along the combustor wall. Small differences in ignition characteristics were found, but no differences in extinction were observed.
