Tato práce se zabývá problematikou popisu síťového provozu pomocí automaticky vytvořeného modelu komunikace. Hlavním zaměřením jsou komunikace v řídicích systémech , které využívají speciální protokoly, jako je například IEC 60870-5-104 . V této práci představujeme metodu charakteristiky síťového provozu z pohledu obsahu komunikace i chování v čase. Tato metoda k popisu využívá deterministické konečné automaty , prefixové stromy  a analýzu opakovatelnosti. Ve druhé části této diplomové práce se zaměřujeme na implementaci programu, který je schopný na základě takového modelu komunikace verifikovat síťový provoz v reálném čase.

La démographie et les modes de vie ont considérablement évolué au cours des dernières décades. De tels changements sont destinés à influencer la conception de l’habitation et ils incluent notamment une série de besoins émergents: s’en suivent des besoins additionnels en espace pour répondre à l’arrivée de ces activités additionnelles au niveau du logement. La planification en vue de répondre à ces besoins émergeants constitue le principal thème de la présente thèse. Dans le cas de la maison unifamiliale détachée, le sous-sol est disponible pour offrir des espaces appropriés à ces besoins émergents. Par contre, une telle ressource n’est normalement pas présente dans le cas d’un édifice multifamilial. La thèse propose un espace additionnel spécifique en vue de répondre à ces besoins émergents : l’espace supplétif. Même si un tel espace n’est pas envisagé dans les publications du domaine, des précédents existent quant à sa présence en planification multifamiliale. Le but de la présente étude est d’offrir des lignes directrices quant à la conception et l’intégration d’un tel espace supplétif. Elle va s’appuyer sur l’approche systémique en raison de la logique de déduire la solution à partir d’une analyse de l’objectif. L’application de l’approche systémique implique donc que tous les critères correspondant à la nature spécifique de l’espace supplétif seront extrapolés à partir de l’objectif. Dans le cas la présente étude, ce sont les critères du bureau à domicile qui seront d’abord précisés car il s’agit de l’activité émergente la plus exigeante. Les critères seront traités comme vecteurs d’un modèle générique indicatif de la manière d’organiser l’espace supplétif. Ce modèle visera le bureau à domicile en vue d’offrir les solutions pertinentes et il se concentrera principalement sur les critères d’intimité visuelle et spatiale. La contribution du modèle sera de suggérer des lignes directrices en vue d’incorporer l’espace supplétif à l’intérieur des édifices résidentiels de type multifamilial, ce que la planification conventionnelle n’offre pas. C’est le concept d’adaptabilité qui est à la base de toute stratégie visant à permettre le changement en architecture et en habitation, d’autant plus lorsqu’il s’agit d’un espace supplétif. À cet effet, l’espace supplétif va recourir à l’approche Open Building afin d’appliquer le concept d’adaptabilité, en raison de ses avantages majeurs tant au niveau conceptuel que constructif. Différentes applications de l’approche Open Building, telles que le projet NEXT21 et le protocole KSI (Kikou support and Infill), offrent des exemples susceptibles de constituer d’efficaces lignes directrices pour la conception d’un espace supplétif. La faisabilité du modèle d’espace supplétif proposé est vérifiable et démontrable dans le monde réel. Les systèmes constructifs industrialisés sont en mesure de permettre le changement sans démolition car leurs joints mécaniques « à sec » rencontrent généralement les normes DfD (Design for Disassembly), non seulement en ce qui concerne l’espace supplétif mais pour l’ensemble du logement. / Demographics and lifestyles have changed considerably in the past few decades. These changes are bound to influence the design of housing and they notably include a series of emerging needs: additional spatial needs due to additional activities brought to the traditional housing premises. Planning for those emerging needs is the main theme of this thesis. In a typical single-family detached house, the basement is available to accommodate the spatial requirements for these emerging needs. However, such a provision does not typically exist in multi-family housing. This thesis proposes a specific additional space to accommodate these emerging needs: the supplementary space. Although such a space has not been explored in the literature, there are precedents for its application in multi-family floor planning. The objective of this study is to provide guidelines for the design and the integration of this supplementary space. It relies on the systems approach as the design-decision methodology due to its logic of deducting the solution from the analysis of the objective. Applying the systems approach means that all the criteria corresponding to the specific purpose of the supplementary space will be extrapolated from the objective. However, once the supplementary space is being used to deal with emerging needs, it will then introduce its own relevant criteria. This study will start with the criteria for designing a home office because this is the most demanding emerging needs activity. The criteria are organized as vectors of a generic model indicating how the supplementary space can be formulated. The model will target the workplace at home and subsequently offer solutions to them. This study focuses on the planning provisions dealing mainly with visual and spatial privacy. The overall outcome of the model is to suggest guidelines to incorporate the supplementary space within multi-family residential buildings, a feature not offered in traditional planning. The concept of adaptability is the key design strategy to accommodate change in architecture and housing, even more in the case of a supplementary space. Therefore, the supplementary space model will apply the concept of adaptability through the Open Building (OB) approach; elaborating more on the practical design and construction features. Different OB applications, such as the NEXT21 project and the KSI (Kikou Support and Infill) protocol in Japan, are examples that can be used as efficient guidelines to design a supplementary space. The feasibility of the supplementary space model can be validated and served in the real world. Industrialized building systems are capable of accommodating change without demolition as their dry mechanical joints are generally at meeting the DfD (design for disassembly) standards, not only for the supplementary space but also for the whole dwelling unit.

This master's thesis explains basics of the longest prefix match (LPM) problem. It analyzes and describes chosen LPM algorithms considering their speed, memory requirements and an ability to implement them in hardware. On the basis of former findings it proposes a new algorithm Generic Hash Tree Bitmap. It is much faster than many other approaches, while its memory requirements are even lower. An implementation of the proposed algorithm has become a part of the Netbench library.

Cette thèse analyse comment la fiction espagnole contemporaine renoue avec la tradition de l’exemplarité littéraire, à travers l’étude d’un corpus de sept œuvres publiées au tournant du XXe (1998-2004). Elle tente de mettre en lumière l’évolution de la notion d’exemplarité dans une perspective diachronique mais aussi synchronique, à travers le prisme du paradigme de pensée contemporain centré sur la notion d’individu. Les nouvelles modalités de l’exemplarité au sein de la prose narrative actuelle sont appréhendées à partir de la réactivation de son support traditionnel — la figure du héros — mais aussi des possibilités nouvelles qu’offrent le questionnement des frontières génériques et l’ambiguïté du pacte de lecture. Dans un monde dépourvu de consensus idéologique, les auteurs du corpus forgent leur propre grille d’interprétation du réel et substituent des réponses éthiques particulières, mais toutefois crédibles et acceptables par le lecteur, à l’imposition de vérités globales et universelles. L’exemplarité, telle qu’elle est à l’œuvre dans le roman actuel, entraîne alors une nouvelle forme d’engagement caractérisée par l’énoncé d’une éthique consubstantielle à la création littéraire. / This thesis analyses how the contemporary Spanish fiction revives the tradition of literary exemplarity, through the study of seven novels published at the turn of the XXth and the XXIst centuries (1998-2004). This work tries to underline the evolution of the exemplarity notion in both diachronic and synchronic perspectives, and the study of the current analytical paradigm focused on the individual. The new forms of exemplarity in contemporary literature are considered through the reactivation of its traditional shape —the hero— but also with the new possibilities given by the questioning of boundaries between genre and the ambivalence of the reading pact. In a world devoid of ideological consensus, the authors of the corpus shape their own frames of understanding. Rather than a universal moral, they suggest subjective ethical answers that can be shared by the reader. The exemplarity, in its actual forms, produces new types of commitment that are based on an ethic inseparable from literary creation.

The thesis is devoted to study of continuum mechanics and thermodynamics and the related mathematical analysis. It consists of four self-contained chapters dealing with different aspects. The first chapter focuses on peridynamics, a non-local theory of continuum mechanics, and its relation to conventional local theory of Cauchy-Green elasticity. Similar compar- isons has been used for proving consistency and for determining some of the material coefficients in peridynamics, provided the material parameters in the local theory are known. In this chapter the formula for the non-local force-flux is computed in terms of the peridynamic interaction, relating the fundamental concepts of these two theories and establishing hence a new connection, not present in the previous works. The second and third chapters are both devoted to Rate-Independent Systems (RIS) and their applications to continuum mechanics. RIS represents a suitable approximation when the internal, viscous, and thermal effects can be neglected. RIS has been proven to be useful in modeling hysteresis, phase transitions in solids, elastoplasticity, damage, or fracture in both small and large strain regimes. In the second chapter the existence of solutions to an evolutionary rate-independ- ent model of Shape Memory Alloys (SMAs) is proven. The model...

<div>The huge gamut of today’s internet-connected embedded devices has led to increasing concerns regarding the security and confidentiality of data. To address these requirements, most embedded devices employ cryptographic algorithms, which are computationally secure. Despite such mathematical guarantees, as these algorithms are implemented on a physical platform, they leak critical information in the form of power consumption, electromagnetic (EM) radiation, timing, cache hits and misses, and so on, leading to side-channel analysis (SCA) attacks. Non-profiled SCA attacks like differential/correlational power/EM analysis (DPA/CPA/DEMA/CEMA) are direct attacks on a single device to extract the secret key of an encryption algorithm. On the other hand, profiled attacks comprise of building an offline template (model) using an identical device and the attack is performed on a similar device with much fewer traces.</div><div><br></div><div>This thesis focusses on developing efficient side-channel attacks and circuit-level low-overhead generic countermeasures. A cross-device deep learning-based profiling power side-channel attack (X-DeepSCA) is proposed which can break the secret key of an AES-128 encryption engine running on an Atmel microcontroller using just a single power trace, thereby increasing the threat surface of embedded devices significantly. Despite all these advancements, most works till date, both attacks as well as countermeasures, treat the crypto engine as a black box, and hence most protection techniques incur high power/area overheads.</div><div><br></div><div>This work presents the first white-box modeling of the EM leakage from a crypto hardware, leading to the understanding that the critical correlated current signature should not be passed through the higher metal layers. To achieve this goal, a signature attenuation hardware (SAH) is utilized, embedding the crypto core locally within the lower metal layers so that the critical correlated current signature is not passed through the higher metals, which behave as efficient antennas and its radiation can be picked up by a nearby attacker. Combination of the 2 techniques – current-domain signature suppression and local lower metal routing shows >350x signature attenuation in measurements on our fabricated 65nm test chip, leading to SCA resiliency beyond 1B encryptions, which is a 100x improvement in both EM and power SCA protection over the prior works with comparable overheads. Moreover, this is a generic countermeasure and can be utilized for any crypto core without any performance degradation.</div><div><br></div><div>Next, backed by our physics-level understanding of EM radiation, a digital library cell layout technique is proposed which shows >5x reduction in EM SCA leakage compared to the traditional digital logic gate layout design. Further, exploiting the magneto-quasistatic (MQS) regime of operation for the present-day CMOS circuits, a HFSS-based framework is proposed to develop a pre-silicon EM SCA evaluation technique to test the vulnerability of cryptographic implementations against such attacks during the design phase itself.</div><div><br></div><div>Finally, considering the continuous growth of wearable and implantable devices around a human body, this thesis also analyzes the security of the internet-of-body (IoB) and proposes electro-quasistatic human body communication (EQS-HBC) to form a covert body area network. While the traditional wireless body area network (WBAN) signals can be intercepted even at a distance of 5m, the EQS-HBC signals can be detected only up to 0.15m, which is practically in physical contact with the person. Thus, this pioneering work proposing EQS-HBC promises >30x improvement in private space compared to the traditional WBAN, enhancing physical security. In the long run, EQS-HBC can potentially enable several applications in the domain of connected healthcare, electroceuticals, augmented and virtual reality, and so on. In addition to these physical security guarantees, side-channel secure cryptographic algorithms can be augmented to develop a fully secure EQS-HBC node.</div>

Alfredo Molano, écrivain et sociologue colombien contemporain, remet en question la concentration de la propriété terrienne et la distribution inégale des richesses. L'étude de son oeuvre explore trois axes centraux. Premièrement, la transformation de son écriture, qui évolue d'un format propre au discours scientifique vers le témoignage journalistique et littéraire. Cet écart par rapport à l'objectivisme scientifique entraîne un certain risque de fictionnalisation, que l'écrivain assume, car, d'après lui, il ne porte aucune atteinte à la factualité des récits et favorise en revanche leur lecture et leur diffusion. Nous avons également analysé la technique, chère à l'écrivain, de l' « imputation », consistant en la fusion de plusieurs témoins en un seul personnage, qui garde les traits des individus dont il s'est inspiré. Notre intérêt s'est aussi porté sur l'hybridation générique, puisque le Colombien fait appel aux récits de vie, de voyages et d'apprentissage, autant qu'aux textes sentimentaux, d'action et d'aventures, et à l'essai, entre autres. Cette confluence reflète la complexité d'une société féodale et postmoderne, et permet l'expression d'une variété de témoins hétérogènes, notamment les Amérindiens, les paysans, les activistes politiques, les délinquants et les prisonniers. Ils sont, pour la plupart, victimes de l'inégalité et du conflit permanent entre le centre hégémonique et la périphérie opprimée, deux pôles aussi flous que la violence est tangible, sanglante et multiforme. Alfredo Molano, comme la plupart des témoins, ne s'en tient pas au constat de cette violence, il la dénonce ouvertement et propose des solutions structurelles. Il s'oriente vers la construction d'une « mémoire historique », reconnaissant la souffrance des victimes, et vise une société non seulement hybride, mais surtout juste et égalitaire. / Alfredo Molano, a contemporary Colombian writer and sociologist, calls into question the concentration of land property and the unequal distribution of wealth. The study of his writing explores three main axes. At first, the transformation of his writing, which advances from a scientific discourse to the journalistic and literary testimony. This distance concerning the scientific objectivism carries away some risk of fictionnalisation. The writer assumes because, according to his point of view, his writing has no effect on the factuality of the stories but it is quite easy to read and to circulate. Then, the writer's technique of the "imputation" has been analysed. The author is really attached to. It consists on the fusion of many witnesses into a single character, who keeps the characteristics of people he was inspired by. Finally, our study of his writing is also focused on generic hybridisation, since the Colombian refers not only to the stories of Life, travel and learning, as well as sentimental texts, action and adventures, but also to the essay, among many others. This confluence reflects the complexity of a feudal and postmodern society, and allows the expression of heterogeneous diversity of witnesses, particularly Amerindians, farmers, political activists, offenders and prisoners. Most of them are victims of the inequalities and the continuous conflict between the hegemonic center and the oppressed periphery, two poles as fuzzy as the violence is palpable, bloody and multiform. Alfredo Molano, like most of his witnesses, does not content himself by the recording of this violence, but he denounces it openly and proposes structural solutions. He turns himself towards the development of a "historical memory", recognizing the suffering of victims and targeting a society not only hybrid, but most of all just and egalitarian. / Alfredo Molano, escritor y sociólogo colombiano, critica la concentración de la propiedad de la tierra y la distribución desigual de la riqueza. Este estudio de su obra explora tres ejes principales. Primeramente, la transformación de su estilo, de un formato propio del discurso científico, hacia el testimonio periodístico y literario. Tal distanciamiento frente al objetivismo científico conlleva cierto riesgo de ficcionalización, asumido por el escritor, para quien ésta no afecta de manera alguna el carácter fáctico de los relatos y, en cambio, facilita su lectura y su difusión. Analizamos igualmente la técnica "molanesca" de la "imputación", consistente en fusionar varios testigos en un solo personaje, el cual conserva los rasgos de los individuos en los que se inspira. Nos hemos interesado también por la hibridación genérica, puesto que el colombiano recurre a las historias de vida, a los relatos de viajes y de aprendizaje, así como a textos sentimentales, de acción y de aventuras, y al ensayo, entre otros. Esta confluencia refleja la complejidad de una sociedad tan feudal como posmoderna y permite la expresión de una serie de testigos heterogéneos, como los amerindios los campesinos, los activistas políticos, los delincuentes y los reclusos. Son ellos, en su mayoría, victimas de la desigualdad y del permanente conflicto entre el centro hegemónico y la periferia oprimida, dos polos tan difusos como tangible, sangrienta y multiforme es la violencia. Alfredo Molano, como casi todos sus testigos, no se limita a constatar dicha violencia; la denuncia abiertamente y propone soluciones de fondo. El escritor trabaja en la construcción de una “memoria histórica” y vislumbra una sociedad no sólo híbrida, sino ante todo justa e igualitaria.

This investigation focused on identifying model foundational strategies to assist Canton Public School District (CPSD) officials in recruiting new teachers, successfully hiring them, and then retaining them the district. Located within the boundaries of the city of Canton, Mississippi, CSPD is geographically located in the central portion of the state. The district consists of 1 high school, 2 middle schools, 4 elementary schools and Canton Education Services Center. CSPD is continually affected by an ever-increasing teacher shortage because new teachers tend to leave the district after they are hired. More than 50% of new teachers leave their teaching positions in the district’s schools within 5 years. The investigation utilized published literature and other archival data (e.g., scholarly papers presented at conferences) accessible to the public in the form of books, chapters in published books, journal articles, and scholarly papers presented at learned societies and associations. Two research questions guided the investigation. The first research question asked: What does the published literature and related archival data (e.g., available scholarly papers retrievable from sources such as colleges, universities, foundations, conferences, etc.) accessible to the public reveal about recruiting, hiring, and retaining teachers? Overall, the material collected and analyzed yielded abundant information. Much of the available information proved valuable because the material focused attention the “how-to-do-it” aspects of recruiting, hiring, and retaining quality new teachers. The second research question asked: Will information gleamed from an analysis of the published literature and other archival data (e.g., unpublished scholarly papers) lead to the development of foundational strategies for assisting school district officials in recruiting, hiring, and retaining new teachers for CPSD? It was possible to develop a model holding potential for improving teacher recruitment, hiring, and retention at CPSD. The model that was developed features seven foundational strategies that if implemented, hold potential for improving teacher recruitment, hiring, and retention at CPSD. The seven strategies are: (1) identify the vacancy and write the job description, (2) announce and advertise the teacher vacancy, (3) develop a customized application form, (4) paper screening process, (5) interviewing process, (6) salary and benefit package, and (7) induction and mentoring.
