Résumé de la thèse en français : En partant, d’un côté, d’une approche socio-historique de la construction de la catégorie de personnes dites « handicapées » en France, et de l’autre d’une étude de la naissance du mouvement et des théories queer dans le monde anglo-saxon, cette thèse a pour but de montrer comment le handicap peut aujourd’hui s’inscrire dans le queer. À l’aide de penseur-es, philosophes, sociologues ou même militant-es de divers horizons, ce travail cherche à élaborer les prémisses d’une pensée crip en France pour montrer les liens, mais aussi certains désaccords, entre une réflexion sur le handicap et son inscription dans des processus si chers au queer. Ainsi, il s’agit de monter notamment en quoi les personnes handicapées s’inscrivent dans un phénomène de retournement du stigmate et de revalorisation de l’abjection tel qu’il a pu être formulé par les personnes queer dont l’insulte désignait leur sexualité déviante. Les concepts queer de désidentification et de performativité peuvent également servir à repenser le handicap en permettant de comprendre, d’une part les fluctuations possibles de l’identité handicapée, et d’autre part l’aspect de mise en scène sociale qu’il peut y avoir dans l’appréhension de ce dernier. Pour finir, la notion foucaldienne reprise par J. Butler d’idéal régulateur permet une étude approfondie de la validité comme socialement construite / Starting from a socio-historical approach of the French constructed catagory "di-sabled"; followed on by a study of Queer Movements and Theories today, thinkers, philoso-phers, sociologists, and activists from various backgrounds have helped to develop this work. The premises of French Crip thaught are analysed through the links and certain disagree-ments between disability and it's inscription in Queer Theory. One of the most important goals of this thesis is to explain how disabled people take part in stigma reversal; as a reva-luing of abjection, formulated be Queer people who through back this insult, indicating their deviant sexuality. The Queer concepts of disidentification and performability can also help to rethink disability; by allowing the understanding of the possible fluctuations in disability iden-tity, including the aspects of social staging in disability. To conclude, the Foucauldian notion of the 'ideal regulator' taken up by Judith Butler allows an in depth study of able-bodiedness as socially constructed

This project explores the rapidly expanding area of AC direct drive for LED lighting. AC LED driving does not use typical DC-DC converter-based driving but uses semiconductor switches and a linear regulator to activate a number of LEDs proportional to the input voltage at any given time. This allows bulky, expensive magnetics to be eliminated from the system. The goal of this project was to design a scaled-down physical AC LED direct drive system to validate the conclusions of methods for improving efficiency from a previous investigation that found minimizing voltage across the linear regulating MOSFET led to higher efficiency at the cost of increased input current THD. This project found that this conclusion is physically realizable, with a final efficiency of 94.46% and an input current THD of 58.9%. This result was achieved by taking the previous investigation’s final design as a starting point and replacing ideal switches and control signals with discrete components. The final version uses a set of comparators and sense resistors to determine when a given LED stack should be on for a simple, analog control solution. Once the system was simulated this way, the assembled version was used to measure efficiency, power factor, current THD, flicker index, and DC supply power. Additional plots of the stack voltages and control signals were collected to verify proper operation and compare to simulation. The final measurements aligned with trends from simulation and result in a simple AC direct drive solution that requires no specialty ICs.

Carotenoids are the precursor of several metabolites with regulatory functions, which include the plant hormones abscisic acid (ABA) and strigolactones (SLs), and signaling molecules, such as β-cyclocitral. These carotenoid-derivatives originate from oxidative breakdown of the double bond resulting in carbonyl cleavage-products designated as apocarotenoids. The cleavage reaction causing apocarotenoid formation is catalyzed frequently by Carotenoid Cleavage Dioxygenases (CCDs). Several lines of evidence indicate the presence of yet unidentified apocarotenoids with regulatory or signaling function. Here, we first characterized the biological functions of the apocarotenoid zaxinone formed by ZAXINONE SYNTHASE (ZAS), a member of an overlooked, widely distributed plant CCD clade. The loss-of-function rice zas mutant contains less zaxinone, exhibiting retarded growth with elevated levels of SLs that determines plant architecture, mediates mycorrhization, and facilitates the germination of root parasitic seeds, such as Striga spp. The zaxinone treatment rescued zas phenotypes, down-regulated SL biosynthesis and release, and enhanced root growth in the wild-type rice seedlings. Next, we performed multi-omics analysis demonstrating zaxinone increased sugar metabolism and induced photosynthesis in a manner that led to phenotypical changes in rice roots. Besides, transcriptome analysis showed that zaxinone upregulated CYTOKININ GLUCOSYLTRANSFERASES expression in roots, which might explain the increase in the apex and meristem length, and in the number of cellular layers. Finally, the investigation of zaxinone biology and the utilization of its application is constrained by its laborious organic synthesis and low abundance in natural sources. Therefore, we developed easy-to-synthesize and highly efficient Mimic of Zaxinone (MiZax), based on the structure-activity-relationship study using a series of apocarotenoids. Activity-based experiments unraveled MiZax3 and MiZax5 were at least as active as zaxinone in rescuing root phenotypes of the zas mutant, promoting root growth in wild-type seedlings, and reducing SL biosynthesis and release. Taken together, zaxinone is a key regulator of rice growth and development, which regulates sugar metabolism, suppresses SL biosynthesis, fine-tunes cytokinins level, and modulates biotic interactions with arbuscular mycorrhizal (AM) fungi. Our work also provides easy-to-synthesize mimics for illuminating zaxinone biology and as a tool to improve crop growth and reduce the infestation by Striga hermonthica, a severe threat to food security worldwide.

With the wide adoption of Internet of Things (IoT) in applications that involve sensitive information, the security of IoT devices is becoming an important concern. IoT devices face many challenges in securing information due to their low cost and computation constrains. To over come such challenges, different techniques have been developed. One such technique is power analysis. However, power analysis requires equipment that is often bulky, power hungry and expensive, making them unsuitable for many IoT applications. This thesis developed two energy signature capturing circuits that can be embedded into low dropout (LDO) voltage regulators. The first design targets analog LDO circuits and the second design is suitable for the newly emerged digital LDOs. Both circuits are designed and simulated using a commercial 130nm CMOS technology. To evaluate the effectiveness of the developed circuits, power traces collected from a wireless sensor device are used in circuit simulations. The results indicate that the developed circuits can detect different model wireless transmission as well as other abnormal operations.

Optimeringen av PID-parametrarna har varit en utmaning sedan uppfinningen avPID-regulatorer. Många olika optimeringsmetoder har tagits fram sedan 1940-talet,i detta arbete testades och jämfördes Ziegler-Nichols stegsvarmetoden, Lambdametoden och AMIGO-metoden.Målsättningen med detta examensarbete var att kunna utse vilken optimeringsmetodsom lämpade sig bäst för processinstrumenten som designats på avdelningen Custimized Bioprocess Solutions (CBS) på Cytiva. Optimeringsmetoden som utses kommer att föreslås som en som en del i en arbetsprocess att följa när ett system behöveroptimeras.Testerna genomfördes med hjälp av stegsvarsmetoden, där de förinställda PIDparametrarna på ett processinstrument användes som referens. Utifrån tre parametrarmodellen kunde nödvändiga data samlas in, sedan beräknades nya PID-parametrarmed de valda optimeringsmetodernas beräkningsregler. De nya PID-parametrarnaanvändes sedan för att generera nya stegsvar. Slutligen jämfördes de nya stegsvarenmot stegsvaret från de förinställda PID-parametrarna för att kunna utse den mestlämpade optimeringsmetoden.Detta arbete resulterade i slutsatsen att fler tester behöver utföras, men att beräkningsverktyget som användes under examensarbetet skall ingå som en del av den efterfrågade arbetsprocessen. / The optimization of the PID parameters has been a challenge since the invention ofPID controllers. Many different optimization methods have been developed sincethe 1940s, in this work the Ziegler-Nichols step response method, the Lambdamethod and the AMIGO method were tested and compared.The aim of this thesis was to be able to choose which optimization method was bestsuited for process instruments designed at the Custimized Bioprocess Solutions(CBS) department at Cytiva . The optimization method that is chosen will be proposed as part of a work process to follow when a system needs to be optimized.The tests were performed using the step response method, where the preset PID parameters on a system were used as a reference. Based on the three parameters model,the necessary data could be collected, then new PID parameters were calculatedwith the calculation rules of the selected optimization methods. The new PID parameters were then used to generate new step responses. Finally, the new step responses were compared to the step response from the preset PID parameters to designate the most suitable optimization method.This work resulted in the conclusion that more tests need to be performed, but thatthe calculation tool used during the degree project should be included as part of therequested work process.

This thesis brings to you a salient theme: Private for-Profit News Media (Print and Broadcast; irrespective of the platform on which it is disseminated) based on an interesting topic: Migration in order to explore theoretically and empirically how to model the social impact of the existence of media in a given socio-political, economic, legal and cultural context namely the United States of America and the United Kingdom at a given period: Year 2015. The study of media in policy studies has been a relatively neglected area in the past and as a student of Public and Social Policy one finds this a most suitable opportunity to do otherwise. Media's role in today's society can be explored from two angles: (1) Media as a tool, a mediator, a conduit and (2) Media as an actor, a regulator, a contributor and this thesis will focus on the latter as it is more important to understand the dynamic role played by this actor named: 'The Media'. The scope of this thesis is three fold: (1) it seeks to analyse media's relationship with the State, Market and Civic sector based on the hypothesis that it is in fact a prominent regulator among the key actors, (2) it seeks to explore media's presence in the policy cycle based on the theory that it is certainly pervasive and (3) it seeks to examine the impact of media in...
