Texto completoMånga inbyggda system saknar en enhet för minneshantering (s.k. MMU) och saknar därför oftast minnesskydd. Detta leder till att dessa system blir mindre robusta eftersom operativsystemet, processer och trådar inte längre är isolerade från varandra. Detta är också en säkerhetsbrist och med antalet inbyggda system som snabbt ökar på grund av tillväxten av Internet of things (IoT), så kan sårbarheter som denna bli ett stort problem. Med en nyligen introducerad uppdatering av RISC-Vprocessor arkitekturen, så introducerades en möjlighet till att isolera minne utan hjälp av en MMU. Denna studie syftar till att identifiera problem och möjligheter av att implementera sådant minneskydd med RISC-V. Baserat på en studie av litteratur och dokumentation om minnesskydd och RISC-V arkitekturen designades och implementerades en prototyp för att hjälpa till att fastställa problem och möjligheter samt göra en utvärdering med avseende på prestanda- och minneskostnader. Den utvecklade prototypen visade en fungerande implementering av minneskydd för minnesregioner med RISC-V. Utvärderingen av prototypen visade en ökad exekveringstid för kontextbyten och ökad minnesanvändning. Resultaten indikerar att det implementerade minneskyddet kommer med en ökad kostnad i prestanda med en konstant faktor och en liten omkostnad i minne. Därför rekommenderas att implementeringar som vill implementera minneskydd med RISC-V på mindre inbyggda system där tid och minne kan vara avgörande tar hänsyn till omkostnaderna. Ytterligare studier och tester behövs för att identifiera optimeringar som kan förbättra prestandan och upptäcka säkerhetsbrister.

Texto completoObemannade såväl som bemannade rymduppdrag har sett ett högt misslyckande i rymdteknikens tidiga era. Detta har dock förbättrats mycket sedan ingenjörer började lära sig av sina tidigare erfarenheter och utrustade kritiska realtidssystem med feldetekteringsmekanismer. Idag är alla flygande enheter utrustade med feldetekterings-, isolerings- och återställningsmekanismer. Däremot kan kostnaden för hårdvara vara ett problem för processen att skapa ett sådant system som är både robust och mottagligt. Denna uppsats analyserar möjligheten att implementera ett feldetekterings-, isolerings- och återställningssystem inuti ett enkelgängat samarbetsplaneringssystem. Denna uppsats föreslår ett samarbete för implementering av ett sådant system, där varje uppgift ansvarar för delar av feldetekteringen. Analysen görs från både integrationsskiktet, över operativsystemet och dess uppgifter, samt från insidan av detekteringssystemet, där två nyckelkomponenter implementeras och analyseras. Resultaten visar att det är möjligt att implementera ett feldetekteringssystem som täcker alla satellitkomponenter och som är mottaglig. Dessutom visar jämförelsen med ett traditionellt, dedikerat feldetekteringssystem att fel kan fångas snabbare med en mottagligmekanism.

Texto completoThe dynamic analysis of large, complex structural systems is computationally intensive and therefore prohibits the use of optimization procedures, which are both iterative and complex with respect to variable search patterns. The solution to this problem is through the use of time and frequency synthesis techniques. They provide a means of rapidly recalculating a system's changed response due to structural modifications, as dictated by the optimization procedure. The efficiency is gained through the fact that the synthesis methods are independent of model size, in that only those model degrees of freedom where changes are made are required in the analysis. Furthermore, these methods are exact in their formulation, including the treatment of non- proportional damping. These structural synthesis techniques are developed in the context of optimal design of shock and vibration isolation systems. Their utility and value is demonstrated in the optimal design of an isolation system for a 109 dof non-proportionally damped structural system. In the course of the optimization, the synthesis techniques make possible 80 transient, frequency response, and static analyses in 2 hours and 39 minutes (desktop computer), while yielding an isolation design which satisfies all design constraints

Texto completoBacillus anthracis is one of the most feared agents of biological warfare and causes the
deadly disease called anthrax. SVA (statens veterinärmedicinska anstalt) is working on a
project together with SLV (statens livsmedelsverk) where the target is to find rapid and
effective detection methods for Bacillus anthracis in animal feed and food samples. Bacillus
subtilis, which is harmless, was used in this study as a model organism to Bacillus anthracis.
A known concentration of vegetative Bacillus subtilis was spiked in animal feed and food
samples. The genomic work flow was based on automated DNA isolation and real time PCR.
The aim of the study was to screen for inhibitory components in the animal feed and food
samples using two different DNA isolation robots; Magnatrix 8000 and Biorobot EZ1. The
results showed that DNA of high quality was extracted from the samples with both robots.
However, the CT-value generated by the real time PCR showed considerable variation
depending on the sample matrix. Some samples, for instance egg and liver, were problematic
and gave low concentrations and high CT-values probably due to inhibitory components in the
samples. Further studies will be needed to solve these problems and optimize the methods that
were used in this study.

Objectives: Prevotella intermedia and Prevotella nigrescens are dark-pigmented, non-motile, anaerobic rods regarded as important bacterial pathogens in the etiology and progression of human chronic periodontitis. Because the bacterial species may not be adequately suppressed in the subgingival microbiota of chronic periodontitis lesions by conventional mechanical root debridement when present in high cultivable proportions, systemic and/or local periodontal chemotherapy is often employed to reduce their subgingival numbers to levels compatible with periodontal health. However, many clinical isolates of P. intermedia and P. nigrescens may exhibit resistance to β-lactam antibiotics prescribed in periodontal therapy via expression of β-lactamase enzymes. Conventional methods of in vitro antibiotic susceptibility testing entail cultivation of targeted bacterial species, with evaluations of whether or not the organism is capable of growing in the presence of critical thresholds of test antibiotics, such as β-lactam antibiotics. Because such conventional in vitro antibiotic testing is time-consuming, expensive, and labor-intensive, there is an urgent clinical need for more rapid assays to determine the susceptibility or resistance of important periodontal pathogens, such as P. intermedia and P. nigrescens, to contemplated periodontal antimicrobial chemotherapy. In this regard, matrix-assisted laser desorption/ionization time-of-flight (MALDI-TOF) mass spectrometry, and associated analytic software for the definitive identification P. intermedia and P. nigrescens in clinical specimens, has been approved for clinical microbiology diagnostic use in the United States by the Food and Drug Administration. This methodology relies upon evaluations of bacterial protein profiles for microbial species identification. Since β-lactamase enzymes conferring bacterial resistance to β-lactam antibiotics are proteins, it is possible that MALDI-TOF mass spectrometry may be able to reliably detect characteristic differences in protein profiles of microorganisms elaborating and not elaborating β-lactamase enzymes. Thus, the potential exists that protein profiles generated by MALDI-TOF mass spectrometry may be used to rapidly distinguish between antibiotic-resistant versus susceptible strains of bacterial species without employing time-consuming, expensive, and labor-intensive culture and in vitro drug testing. As a result, this study aimed carry out a proteomic comparison of amoxicillin-resistant and susceptible periodontal P. intermedia and P. nigrescens clinical isolates with MALDI-TOF mass spectrometry. Methods: A total of 10 amoxicillin-resistant and two amoxicillin-susceptible fresh clinical subgingival isolates of P. intermedia, and 10 amoxicillin-resistant and one amoxicillin-susceptible clinical subgingival isolates of P. nigrescens, were recovered by culture and identified to species level with MALDI-TOF mass spectrometry from the subgingival dental plaque biofilms of adults with severe chronic periodontitis. The amoxicillin-resistant clinical isolates of P. intermedia and P. nigrescens exhibited growth on anaerobically-incubated enriched Brucella blood agar primary isolation culture plates supplemented with amoxicillin at 8 μg/ml, whereas no growth on these plates was found with amoxicillin-susceptible strains. Normalized raw mass spectra, as well as normalized peak list spectrum representations, generated by MALDI-TOF mass spectrometry within a routine operating range of 2-20 kDa were visually compared for the amoxicillin-resistant and amoxicillinsusceptible P. intermedia and P. nigrescens clinical isolates, to see if there were consistently reproducible differences in their distribution of mass spectra peaks. Results: Visual comparisons of normalized raw mass spectra, and normalized peak list spectrum, for amoxicillin-susceptible and amoxicillin-resistant subgingival clinical isolates of both P. intermedia and P. nigrescens failed to reveal consistently reproducible differences in their distribution of mass spectra peaks within a routine MALDI-TOF mass spectrometry operating range of 2-20 kDa. Conclusions: Visual examination of raw mass spectra and mass spectra peaks generated by MALDI-TOF mass spectrometry within a routine operating range of 2-20 kDa failed to reveal noteworthy differences between amoxicillin-resistant and amoxicillin-susceptible subgingival clinical isolates of P. intermedia and P. nigrescens. These findings indicate that use of MALDI-TOF mass spectrometry employed within a routine operating range of 2-20 kDa may not provide sufficient differentiation in protein profiles between amoxicillin-resistant and amoxicillin-susceptible Prevotella species to be of rapid diagnostic use for assessing the species in vitro antibiotic susceptibility to β- lactam antibiotics. Additional evaluation of MALDI-TOF mass spectrometry employing higher kDa ranges beyond a routine upper operating range of 20 kDa is warranted to further evaluate its potential to accurately identify antibiotic-resistant versus susceptible strains of pathogenic microorganisms.

axial earthquake loads in order to understand the effects under such circumstances. Seven near fault earthquake data were selected by considering possession of directivity. Several runs using the chosen earthquakes were performed in order to be able to derive satisfactory comparisons between different types of isolators. Analytical calculations were conducted using well known structural analysis software (SAS) SAP2000. Nonlinear time history analysis was performed using the analytical model of the bridge with and without seismic isolation. Response data collected from SAS was used to determine the vertical load on the piers and middle span midspan moment on the steel girders due to the vertical and horizontal component of excitation. Comparisons dealing with the effects of horizontal only and horizontal plus vertical earthquake loads were introduced.

Texto completoWhen confronted to a new environment, the visual system faces too much information intake and cannot process it all at once. Before any eye movement, early automatic attention explores the visual scene in order to select relevant items.Recent research revealed that the exploration of the visual scene is not a random process, but is based on the respective saliency of the items in the field. Salience is not a characteristic of an item per se but is emerging as a result of the comparison between an item and its visual neighborhood. For instance, a yellow flower in a garden of red flowers will be considered as more salient than the others in its visual neighborhood. Thus, a hierarchical ordering of the items is continuously established in a preattentive stage, and consists in a sorting of every element from the most to the least salient. Attention, then, relies on this hierarchy to progress in the visual field. The present dissertation had for objective to investigate the cognitive mechanisms involved in this phenomenon: what mechanisms support the salience-based progression of visual attention? Several papers are reported here and explored this question with experimental Psychology.Moreover, numerous works in Psychology, Neurophysiology and Neuroimaging took interest in the neural substrate of visual attention and revealed several key-structures that would subtend the mechanisms involved in attentional functions. However, when it comes to the salience-based progression of attention, only one study could bring cues of the involvement of certain visual pathways in this phenomenon. Another objective of the present dissertation was to define the cortical and sub-cortical structures that constitute those pathways, in order to explore their roles in the salience-base progression of attention. Several papers in the present report are investigating this aspect through Psychophysics and Electroencephalography studies

Texto completoRésumé: Les ponts routiers ont une grande valeur dans un pays parce qu’en cas de catastrophe naturelle, ils peuvent servir comme des lignes pour sauver des vies. Étant vulnérable sous des charges sismiques importantes, on peut considérer différentes méthodes pour concevoir des ponts routiers résistants et également pour réhabiliter des ponts existants. Dans cette étude, l'isolation de la base a été considérée comme une méthode efficace qui peut réduire significativement les effets des charges sismiques sur la structure. En réduisant la demande en ductilité sur la structure sans une augmentation notable de force, la structure est conçue pour rester élastique sous des charges sismiques. Le problème associé aux ponts isolés, particulièrement avec des appuis en élastomère, peut être leurs déplacements excessifs sous les charges de service et de séisme. Ceci peut défier l’objectif d'utiliser des appuis en élastomère pour les ponts typiques de petite portée où les joints de dilatation et les dégagements peuvent aboutir à une augmentation significative des frais d'exploitation et de maintenance. Ainsi, supplémenter la structure avec des amortisseurs d’une certaine rigidité peut servir de solution, ce qui peut cependant augmenter l’effort tranchant transmis à la sous-structure. Cette étude a pour but de fournir une méthode simplifiée afin d’évaluer les paramètres optimaux des amortisseurs dans les ponts isolés. Dans cette thèse, premièrement, basé sur une étude paramétrique, quelques directions sont données pour l'utilisation de dispositifs d'isolation simples, dont les appuis en élastomère, afin de réhabiliter des ponts existant avec une haute importance. Les paramètres comme la géométrie du pont, les clauses des normes et le type de sol sur lequel la structure est construite ont été appliqués sur un pont typique de deux portées. Il est conclu que les paramètres mentionnés peuvent déterminer l'emploi d'isolement de la base des ponts routiers. À la deuxième phase, basé sur le coefficient de réponse élastique des ponts isolés, une méthode de conception simplifiée d’amortisseur pour des ponts routiers réguliers isolés à la base a été présentée dans cette étude. En sélectionnant des objectifs pour la réduction du déplacement et la variation de l’effort tranchant, la rigidité et l'amortissement exigés d'un amortisseur hystérétique peuvent être déterminés. L’étude s’est poursuivie par une modélisation numérique d’un pont à deux portées pour vérifier l'efficacité de la méthode. Pour un modèle numérique d'un pont isolé typique, la méthode a été utilisée pour identifier des paramètres linéaires équivalents pour un certain déplacement et effort tranchant désigné. Par la suite, assumant un amortisseur de type hystérétique, les paramètres non linéaires de l’amortisseur ont été calculés et utilisés. La comparaison des résultats du modèle numérique sans amortisseur et avec l'amortisseur a démontré que la méthode proposée est suffisamment précise. Par la suite, un nouvel amortisseur hystérétique simple en acier a été conçu. Cinq spécimens ont été fabriqués de deux différents grades d’acier et ont été testés en combinaison avec un isolateur à l’échelle réelle dans le laboratoire de structures de l'Université de Sherbrooke. La procédure comprenait la caractérisation des spécimens par des tests cycliques en contrôle de déplacement et par la suite la réalisation d’essais par la méthode de sous-structuration dynamique en temps réel. Les résultats des essais ont été utilisés pour établir un modèle numérique du système qui a subi des analyses temporelles non linéaires sous plusieurs séismes. Le résultat des essais expérimentaux et numériques montrent une conformité acceptable avec la méthode simplifiée.

Texto completos, automobile tires have been produced by means of vulcanizing rubber with steel mesh in different forms which have a similar effect as the steel plates or fibers inside the conventional elastomer-based isolators. Therefore, rectangular shaped layers cut from tread sections of used tires and then piled on top of each other can function as an elastomeric bearing. Since the tires are being designed for friction, load transfer between scrap tire layers would be large enough to keep all layers intact. A minimal slip generated between the piled layers at high strain rates may even help to dissipate some extra energy. Axial compression, dynamic free vibration, static shear and shaking table tests have been conducted on Scrap Tire Pads (STP) prepared by using different tire brands for different number of layers and orientations. The results have shown that the average shear modulus of STPs change between 0.9MPa and 1.85MPa. At the end of the dynamic tests it has been noticed that the lateral stiffness of STPs can be simply adjusted by changing the number of tread layers placed on top of each other. The amount of wire mesh inside the tire tread layers is relatively low compared to the steel plates in regular elastomeric pads
consequently, axial load capacity of STPs has been found to be around 8.0MPa. Static large deformation shear experiments have been performed to obtain the horizontal stiffness and shear modulus values at high strains and the results are tabulated in the manuscript. Steel and rubber layers are produced separately and just put on top of each other without any adhesive to form the ¼
scaled versions of STPs which were used to isolate a ¼
scaled masonry house on the shaking table available in METU Structural Laboratory. The experiment showed that non-vulcanized rubber-steel layers put on top of each other can also be used to isolate structures. In conclusion, STPs may be used as a low-cost alternative to conventional elastomer-based pads for seismic isolation of massive structures (e.g. stone wall rural masonry) or for temperature induced deformation compensation of rural bridges. STP usage is demonstrated using three hypothetical design examples in the manuscript.

Texto completoMcDaniel, Keith S. Three Dimensional Simulation of Time-DependentScramjet Isolator / Combustor Flowfields Implemented onParallel Architectures, ( Under the directions of Dr. J. R. Edwards). The development of a parallel Navier-Stokes solver for computing time-dependent,three-dimensional reacting flowfields within scramjet (supersonic combusting ramjet)engines is presented in this work. The algorithm combines low-diffusion upwinding methods, timeaccurate implicit integration techniques, and domain decomposition strategies to yield an effectiveapproach for large-scale simulations. The algorithm is mapped to a distributed memoryIBM SP-2 architecture and a shared memory Compaq ES-40 architecture using the MPI-1 message-passingstandard. Two and three-dimensional simulations of time-dependent hydrogen fuel injection into a modelscramjet isolator / combustor configuration at two equivalence ratios are performed. Thesesimulations are used to gain knowledge of engine operability, inlet performance, isolatorperformance, fuel air mixing, flame holding, mode transition, and engine unstart.Results for an injection at a ratio of 0.29 show qualitative agreement withexperiment for the two-dimensional case, but revealed a slow progression towardengine unstart for the three-dimensional case. Injection at an equivalence ratio of 0.61resulted in engine unstart for both two-dimensional and three-dimensional cases.Engine unstart for the three-dimensional case occurs as a response to the formation and growthof large pockets of reversed flow along the combustor side wall. These structuresdevelop at an incipient pressure above 154 kPa and result in significant blockage of the core flow,additional compression, and chemical reaction within the boundary layer. All of these factors promotea much more rapid unstart as compared with the two-dimensional case.

Texto completoGround vibration induced by human activity such as industrial activities, car or truck traffic, or pilling and blasting in construction or deconstruction operation, generally reaches the troublesome limit for men and occasionally attains the harmful limit. In the densely populated urban regions and buildings housing sensitive equipments, ground vibration has to be strictly controlled. Up to now, many vibration reduction methods have been proposed, one of which is the installation of wave barrier between the dynamic sources and the protected structures. Over the past decades, the vibration isolation effectiveness of wave barrier has been extensively studied. However, to the best of the writer’s knowledge, there is little study about the mutual influence of the parameters of soil-barrier system on the barrier screening efficiency, and the optimization design for wave barrier is rare as well. On the other hand, the influence of ground vibration generated by explosions on the nearby existing tunnel has attracted more and more attention due to the recent damage or even failure of tunnels. Up to now, there are few mitigation measures comprehensively proposed by researchers and engineers for the tunnel vibration reduction during explosions. To overcome those drawbacks, this dissertation focuses on the investigation of the influence of various parameters of soil-barrier system on the barrier isolation efficiency. Key parameters are identified. More importantly, an optimization design method is developed, aiming to find out the desirable barrier that is able to minimize the ground vibration in protected site. Besides, the dynamic behavior of existing tunnel under nearby explosions is examined. Parameters that significantly affect the response of tunnel are pointed out. Furthermore, two practical mitigation measures: the installation of a protective layer along the tunnel lining and time-delayed explosions (rather than instantaneous explosions), are presented with details. The research in this dissertation is able to provide a good reference for the optimization design of wave barrier in reducing ground vibration in protected site and for the design of practical mitigation measures to protect existing tunnel from nearby explosions
