yes / Coinciding with advances in whole-slide imaging scanners, it is become essential to automate the conventional image-processing techniques to assist pathologists with some tasks such as mitotic-cells detection. In histopathological images analysing, the mitotic-cells counting is a significant biomarker in the prognosis of the breast cancer grade and its aggressiveness. However, counting task of mitotic-cells is tiresome, tedious and time-consuming due to difficulty distinguishing between mitotic cells and normal cells. To tackle this challenge, several deep learning-based approaches of Computer-Aided Diagnosis (CAD) have been lately advanced to perform counting task of mitotic-cells in the histopathological images. Such CAD systems achieve outstanding performance, hence histopathologists can utilise them as a second-opinion system. However, improvement of CAD systems is an important with the progress of deep learning networks architectures. In this work, we investigate deep YOLO (You Only Look Once) v2 network for mitotic-cells detection on ICPR (International Conference on Pattern Recognition) 2012 dataset of breast cancer histopathology. The obtained results showed that proposed architecture achieves good result of 0.839 F1-measure.

Ferroelectric field-effect transistors (FeFET) based on hafnium oxide offer great opportunities for Logic-in-Memory applications, due to their natural ability to combine logic (transistor) and memory (ferroelectric material), their low-power operation, and CMOS compatible integration. Besides aggressive scaling, dense integration of FeFETs is necessary to make electronic circuits more area-efficient. This paper investigates the impact of ultra-dense co-integration of a FeFET and an n-type selector FET, sharing the same active area, arranged in a 2TNOR memory array. The examined FeFETs exhibit a very similar switching behavior as FeFETs arranged in a standard AND-type array, indicating that the ultra-dense co-integration does not degrade the FeFET performance, and thus, paves the path to a very fine-grained, ultra-dense Logic-in-Memory implementation. Based on this densely integrated 2TNOR array we propose a very compact design of a 4-to-1 multiplexer with a build-in look-up table, thus directly merging logic and memory.

In dieser Arbeit wird die Möglichkeit untersucht, durch die Messung magnetischer Streuflüsse und unter Berücksichtigung der durch die Steuerströme hervorgerufenen Durchflutung, auf die Position des Rotors im Magnetlager zu schließen. Die Streuflüsse werden in der Regel vernachlässigt, stehen aber im unmittelbaren Zusammenhang zur Luftspaltlänge, wie theoretische Betrachtungen zeigen. Anhand von analytischen und numerischen Modellen, welche durch Messungen verifiziert werden, ist eine Linearisierung und Kompensation des Einflusses der Durchflutung möglich. Auf dieser Basis wird ein Messsystem entwickelt, mit dem die streuflussbasierte Positionsregelung eines Testlagers realisiert wird. Hierfür kommen Hall-Sensoren zum Einsatz, die auf Leiterplatten sitzen, welche anstelle der konventionellen Nutverschlüsse in das Magnetlager eingebracht werden. Aufgrund der direkten Nähe der Sensoren zu den Lagerspulen und der gepulsten Steuerströme weisen die Messsignale jedoch ein erhebliches Rauschen auf. Um dem entgegenzuwirken, kommt ein Kalman-Filter zum Einsatz, mit dem eine deutliche Verbesserung der Signalqualität erreicht werden kann.:Verzeichnis der Formelzeichen, Indizes und Abkürzungen vii 1

rotor in magnetic bearings by measuring magnetic leakage fluxes is investigated. These are usually neglected, but are directly related to the air gap length, as theoretical considerations show. In addition, the magnetic flux caused by the control currents must be taken into account. By means of analytical and numerical models, which are verified by measurements, a linearization and compensation of the influence of the magnetic flux is possible. Based on this, a measurement system is developed to realize a flux leakage-based position control of a test bearing. For this purpose, Hall-sensors are used, which are located on printed circuit boards that are inserted into the magnetic bearing instead of the conventional slot locks. However, due to the direct proximity of the sensors to the bearing coils and the pulsed control currents, the measurement signals exhibit considerable noise. To counteract this, a Kalman-filter is used to achieve a significant improvement in signal quality.:Verzeichnis der Formelzeichen, Indizes und Abkürzungen vii 1 Einleitung 1 1.1 Exkurs . . . . . . . .

Since February 2020, the world is in a COVID-19 pandemic [1]. Researchers around the globe are pitching in to develop a fast reliable, non-invasive testing methodology to solve this problem and one of the key directions of research is to utilize coughs and their corresponding vocal biomarkers for diagnosis of COVID-19. In this thesis, we propose a fast, real-time cough detection pipeline that can be used to detect and localize coughs from audio samples. The core of the pipeline utilizes the yolo-v3 model [2] from vision domain to localize coughs in the audio spectrograms by treating them as objects. This outcome is transformed to localize the boundaries of cough utterances in the input signal. The system to detect coughs from CoughVid dataset [3] is then evaluated. Furthermore, the pipeline is compared with other existing algorithms like tinyyolo-v3 to test for better localization and classification. Average precision(AP@0.5) of yolo-v3 and tinyyolo-v3 model are 0.67 and 0.78 respectively. Based on the AP values, tinyyolo-v3 performs better than yolo-v3 by atleast 10% and based on its computational advantage, its inference time was also found to be 2.4 times faster than yolo-v3 model in our experiments. This work is considered to be novel and significant in detection and localization of cough in an audio stream. In the end, the resulting cough events are used to extract MFCC features from it and classifiers were trained to predict whether a cough has COVID-19 or not. The performance of different classifiers were compared and it was observed that random forest outperformed other models with a precision of 83.04%. It can also be inferred from the results that the classifier looks promising, however, in future this model has to be trained using clinically approved dataset and tested for its reliability in using this model in a clinical setup. / Sedan februari 2020 är världen inne i en COVID-19-pandemi [1]. Forskare runt om i världen satsar på att utveckla en snabb tillförlitlig, icke-invasiv testmetodik för att lösa detta problem och en av de viktigaste forskningsriktningarna är att använda hosta och deras motsvarande vokala biomarkörer för diagnos av COVID-19. I denna avhandling föreslår vi en snabb pipeline för hostdetektering i realtid som kan användas för att upptäcka och lokalisera hosta från ljudprover. Kärnan i rörledningen använder yolo-v3-modellen [2] från syndomänen för att lokalisera hosta i ljudspektrogrammen genom att behandla dem som objekt. Detta resultat transformeras för att lokalisera gränserna för hosta yttranden i insignalen. Systemet för att upptäcka hosta från CoughVid dataset [3] utvärderas sedan. Dessutom jämförs rörledningen med andra befintliga algoritmer som tinyyolo-v3 för att testa för bättre lokalisering och klassificering. Genomsnittlig precision (AP@0.5) för modellen yolo-v3 och tinyyolo-v3 är 0,67 respektive 0,78. Baserat på AP-värdena fungerar tinyyolo-v3 bättre än yolo-v3 med minst 10% och baserat på dess beräkningsfördel befanns dess inferenstid också vara 2,4 gånger snabbare än yolo-v3- modellen i våra experiment. Detta arbete anses vara nytt och viktigt för att upptäcka och lokalisera hosta i en ljudström. I slutändan används de resulterande hosthändel-serna för att extrahera MFCC-funktioner från det och klassificerare utbildades för att förutsäga om en hosta har COVID-19 eller inte. Prestanda för olika klassificerare jämfördes och det observerades att slumpmässig skog överträffade andra modeller med en precision på 83.04%. Av resultaten kan man också dra slutsatsen att klassificeraren ser lovande ut, men i framtiden måste denna modell utbildas med hjälp av kliniskt godkänd dataset och testas med avseende på dess tillförlitlighet vid användning av denna modell i ett kliniskt upplägg.

L’état actuel de l’étude psychosociale du rapport entre Français d’origine européenne et Français d’origine maghrébine en France fait apparaître un morcellement des connaissances dû à la diversité des champs théoriques investis mais aussi à la complexité de ce rapport lui-même et des enjeux auxquels il est rattaché. Le présent travail se propose ainsi de rendre compte, à partir d’un socle épistémothéorique psychosocial commun, de l’historicité, de la contextualité et de la richesse phénoménologique qui caractérisent ce rapport. En raison de l’inscription socio-historique et de la participation sociale en jeu, la théorie des représentations sociales et le paradigme des partitions sociales constituent le cadre théorique dont l’articulation opérationnalise le regard psychosocial qui a été appliqué. Cette articulation a donné lieu à une architecture de contributions empiriques mêlant analyses qualitatives (notamment de presse) et dispositifs expérimentaux.Au total, cinq études ont été réalisées. La première étude s’intéresse aux élaborations représentationnelles autour de l’immigration maghrébine et fait ressortir la nécessité d’intégrer le rapport à la France dans l’étude du rapport aux Français d’origine maghrébine pour appréhender les jeux d’opposition, de domination et d’inclusion-exclusion qui sont à l’œuvre. Les résultats montrent également le caractère co-constructiviste des relations et représentations et soutiennent la pertinence d’un examen de l’intervention des distances psychosociales possibles, notamment entre « Français » et « Arabes », dans la structuration des représentations relatives aux « Arabes ». Les deux études subséquentes s'interrogent alors sur l’articulation entre rapport aux « Arabes », rapport aux « Français » et construction des représentations des « Arabes », auprès de participants se déclarant Français d’origine européenne, dans un contexte intragroupe (entre « Français ») et dans un contexte intergroupe (avec un « Arabe »). Il ressort que le bloc « représentations-rapports » remplit des fonctions de contextualisation et est lui-même profondément adaptable à l’interaction. Une troisième étude interroge l’utilisation, dans les deux précédentes contributions, des désignations « Français » et « Arabes ». Elle porte ainsi exclusivement sur les désignations des Français d’origine européenne et des Français d’origine maghrébine auprès de participants issus des deux catégories. Au moyen d’entretiens inspirés par la méthode d’étude des partitions sociales, les résultats amènent à retenir « Français », « Arabes » et « Maghrébins » comme les désignations qui permettent le plus finement possible d’analyser le rapport entre les deux catégories.À partir de ces termes, une dernière étude utilise les représentations pour examiner de manière articulée (1) le type de relation entre « Français » et « Arabes », d’une part, et « Français » et « Maghrébins », d’autre part, (2) la réflexivité des Français d’origine européenne dans le cadre de ce rapport et (3) l’insertion symbolique de la France. À partir d'unemanipulation du contexte catégoriel d’interaction (intragroupe versus intergroupe), une lecture des résultats propose de voir la polymorphie de ce rapport comme formes de maîtrise, de défense et de projection à partir desquelles la stigmatisation, la dégradation et l’exclusion sont, paradoxalement, les expressions d’un mode spécifique de transaction psychosociale dans lequel il ne s’agit pas de rejeter les Français d'origine maghrébine en dehors de la France.Malgré la complexité de l’articulation théorique et de la démarche méthodologique, le présent travail démontre la possibilité d’étudier d’un point de vue psychosocial unifié des phénomènes aussi multiples, divers et complexes que ceux relatifs au rapport aux Français d’origine maghrébine en France. / The current state of the psychosocial study of the relation between French from European origin and French from Maghrebi origin in France reveals a fragmentation of knowledge due to the diversity of the invested theoretical fields but also to the complexity of this relation itself and the issues to which it is attached. The present work thus proposes to account, from a common epistemo-theoretical psychosocial basis, for the historicity, the contextuality and the phenomenological richness that characterize this relationship. Because of the socio-historical inscription and the social participation at stake, the theory of social representations and the paradigm of social partitions constitute the theoretical framework whose articulation operationalizes the psychosocial look that has been applied. This articulation gave rise to an architecture of empirical contributions combining qualitative analyzes (in particular newspapers’ articles) and experimental devices. In total, five studies were conducted. The first study focuses on representational elaborations around Maghrebi immigration to France and highlights the need to integrate the relation to France in the study of the relation to French from Maghrebi origin in order to apprehend the games of opposition, domination and inclusion-exclusion that are at work. The results also show the co-constructivist character of relations and representations and support the relevance of an examination of the intervention of possible psychosocial distances, in particular between "French" and "Arabs", in the structuring of representations of "Arabs". The two subsequent studies then question the articulation between the relation to "Arabs", the relation to "French" and the construction of representations of "Arabs", among participants declaring themselves French of European origin, in an ingroup context (between "French") and in an intergroup context (with an "Arab"). It appears that the "representations-relations" block fulfills contextualizing functions and is itself deeply adaptable to the interaction. A third study questions the use, in the two previous contributions, of "French" and "Arabs" as groups’ designations. It thus relates exclusively to the designations of the French of European origin and the French of Maghrebi origin among participants from both categories. By means of interviews inspired by the method of study of social partitions, the results lead us to retain "French", "Arabs" and "Maghrebis" as the designations that should allow the finest possible analysis of the relations between the two categories. Based on these designations, a last study uses representations to examine in an articulated way (1) the type of relationship between "French" and "Arabs", on the one hand, and "French" and "Maghrebis", on the other hand, (2) the reflexivity of the French of European origin in the context of this relation and (3) the symbolic insertion of France. Through a manipulation of the categorical context of interaction (ingroup versus intergroup), a reading of the results suggests to see the polymorphism of this relation as forms of control, defense and projection from which stigmatization, degradation and exclusion are, paradoxically, the expressions of a specific mode of psychosocial transaction in which it is not a question of rejecting the French of Maghrebi origin outside France. Despite the complexity of the theoretical articulation and the methodological approach, the present work demonstrates the possibility of studying, from a unified psychosocial point of view, phenomena as multiple, diverse and complex as those relating to the relation with the French of Maghrebi origin in France.

We aim to present the writer Carmen Soler (1924- 1985), unknown in Brazil. Her lyrical female writing is the starting point of poetry in the Paraguayan literary context, as a poet and revolutionary in the dictatorship years. We present theoretical reflections and referrals that elucidate the approach of Comparative Literature, through a descriptive methodology. For this research, we have as corpus the work Poemas (1970), because it is the the only publication made by Soler while living, tracing a parallel with the Chilean Maria Luisa Bombal (1910-1980) in the novels A Última Névoa (1935) and A Amortalhada (1938). - considering what differs them and what approximates them, because even without having ever seen each other, however, they are moved by the love for writing. This study also aims to theorize the look and the literature, intercross the vision of the authors, the look that narrates in the works, offer this eye in the eyes of young women writers, allow the reader to see them, for every encounter is fascinating. The work has the context of the patriarchal society from 1930 to 1980, twentieth century. From a bibliographical point of view, the theoretical scope is anchored, especially, with Merleau-Ponty (2013), in his work O olhar e o espírito (Eye and mind); with Novaes, in his work O Olhar (1993); with Benjamin, in O narrador (The storyteller) (1994), in the poetry of Baudelaire, among others; Paraguayan Literature, by Miguel Àngel Fernandez (2011); and about Bombal, Kahmann (2010) Marcari (2013), Hosiasson (2013) and Figueiredo (2015). The memory, in Le Goff (1990), in addition to bibliographic support and images of Carmen Soler provided by the writer's family. / Esta dissertação propõe analisar a temática “o olhar e a literatura” na lírica e no romance latino-americano. Objetivamos apresentar a escritora Carmen Soler (1924- 1985), desconhecida em âmbito brasileiro. Sua escrita feminina lírica é o marco inicial da poesia no contexto literário paraguaio, como poeta e revolucionária nos anos da ditadura. Apresentamos reflexões teóricas e encaminhamentos que elucidam a abordagem da Literatura Comparada, por meio de uma metodologia comparativa em diversas e várias formas de arte, bem como suportes do olhar na tecnologia. Para esta pesquisa, tem-se como corpus a obra Poemas (1970), pois é a única publicação em vida de Carmen Soler, traçando um paralelo com a chilena Maria Luisa Bombal (1910- 1980) nos romances A última névoa (1935) e A Amortalhada (1938) - considerando o que as difere e o que as aproxima, e, mesmo sem nunca terem se visto, são próximos seus anseios movidos pelo amor à escrita. Este estudo também visa teorizar o olhar e a literatura, entrecruzar a visão das autoras com o escopo teórico, bem como com objetos da teoria literária, apoiada na música, pintura e tecnologia. O olhar que narra nas obras tende a oferecer esse olho no olho das jovens escritoras, permitir ao leitor vê-las, em um diálogo com obras históricas da literatura e arte, já que todo encontro é encantador. O trabalho tem o contexto da sociedade patriarcal de 1930 a 1980, século XX. De cunho bibliográfico, de análise comparativa, o escopo teórico se ancora, especialmente, em Merleau-Ponty (2013), em sua obra O olhar e o espírito; em Novaes, em sua obra O Olhar (1993); em Benjamin, em O Narrador (1994), nas obras de Baudelaire, o olhar flâneur que vê e defende o povo em O ar e os Sonhos (1990) e A água e os sonhos (1998), A memória, em Le Goff, História e Memória (1990). A Literatura paraguaia, por Miguel Àngel Fernandez (2011); e sobre Bombal, Kahmann (2010), Marcari (2013), Hosiasson (2013) e Figueiredo (2015). Além disso, há o apoio bibliográfico e de imagens de Carmen Soler cedidas pela família da escritora.

In Fred Chappell’s Kirkman tetralogy, narrator Jess Kirkman synthesizes a multiplicity of perspectives for understanding the nature of truth. Blurring the distinction between art and life, Jess's narrative structure mirrors the imaginative reconstruction of experience; the novels are largely non-chronological emotive interactions with and reflections of his most salient memories and imaginings. Synthesizing an impressive cacophony of voices, Jess's stories both describe and apply the wisdom and tales Jess acquires from and with his family members. Each story informs the prior and the next, and the rhizomatic interaction between language, narrative, and reader explores Jess's numerous identities and understandings as narratives venture through space, time, and imagination.

Chen, Rosenberg和Shepp（1997）的“雙人決策者的秘書問題“（A Secretary Problem with Two Decision Makers），探討在完整訊息（Full Information）與選擇次序不變的情況下，具有優先選擇權的決策者佔有較大優勢。這裡所謂的優勢意指在雙方最終選擇的大小為勝負條件所產生獲勝機率的比較。而本篇文章主要是延伸此一探討，意即在若不變動兩者選擇的次序，但賦予後選擇決策者較多資訊的條件下，能否平衡雙方的優劣勢。我們首先討論後決策者擁有預知下一步（One-step look-ahead）資訊能力的條件下，雙方優勢的改變；隨之若是在後決策者能預知完全資訊的情況下，是否能平衡雙方的優劣勢。而事實上，即便在後決策者擁有所有資訊的條件，仍無法完全改變此一情況；更進一步而言，先選擇決策者甚至在不知道後決策者已掌握了所有資訊的情況下，仍可佔有獲勝機率大於後決策者的優勢。這裡我們將提供理論與理論上的數值結果。 / Chen, Rosenberg, and Shepp (1997) considered a variation of the "secretary problem" in which the salary demands of a group of applicants are from a known and continuous distribution (i.e., full information case) and these applicants are interviewed sequentially by two managers, say, I and II. For every applicant. Manager I has the right to interview and hire him/her first. If Manager I rejects the applicant, Manager II can interview him/her. No recall is allowed when the applicant is rejected by both managers, and neither manager can interview and hire another applicant once he/she has hired an applicant. The manager who chooses the applicants with the lower salary wins the game. Chen et al. shows that manager I has bigger winning chance than manager II in the full information case. This study is to extend the paper by Chen et al., by giving extra information to manager H. In particular, suppose that manager II can look a few applicants ahead, i.e., he/she knows the salary demands of applicants before manager I interview them. However, under the full-information assumption, even if manager II is a clairvoyant, who claims to be able to see what will happen in the future, his/her winning probability is still less than that of manager I. We provide theoretical proof and simulation to confirm this result.

Este trabajo propone un acercamiento doble a la novela La Revuelta de Sonia Montecino, donde pensamos que tanto la teoría queer como el origen mapuche son de gran importancia en la construcción identitaria de la protagonista. Nuestro análisis consiste en un intento de relacionar la búsqueda de una identidad por parte de la protagonista, mediante una subversión del sexo, por un lado, y mediante la vuelta a los ancestros, por otro. La hipótesis principal de nuestro trabajo es que La Revuelta presenta una propuesta alternativa sobre la construcción identitaria femenina. Para abarcar nuestra investigación nos empleamos de diferentes herramientas metodológicas, como la teoría queer desarrollada por Judith Butler y la cultura mapuche sintetizada por el antropólogo Rolf Foerster. Al igual que nos detenemos en los estudios del sociólogo chileno Jorge Larraín que nos sirven para comprender el contexto en el que se sitúa la trama de la novela, asimismo como recurrimos a Genette y Greimas para llevar a cabo un estudio narratológico, dado que nuestro cuerpo de investigación ha sido un texto narrativo. / This paper proposes the use of a dual approach of queer theory and the importance of the indigenous Mapuche identity, to analyze the identity construction of the protagonist in the novel La Revuelta. The analysis is an attempt to relate the search for identity by the protagonist, through a subversion of gender on the one hand and the return to the ancestral past on the other. The main hypothesis of our work is that La Revuelta presents an alternative proposal on female identity construction. To execute our research we employ different methodological tools, such as queer theory developed by Judith Butler and the theories on Mapuche culture compiled by anthropologist Rolf Foerster. We also focus on the studies of the Chilean sociologist Jorge Larraín, which allow us to understand the context in which the plot of the novel is set, as well as referring to Genette and Greimas in order to conduct a narratological study.

In my dissertation, I present ATLAS — the Auto-Training Look-Ahead Scheduler. ATLAS improves service to applications with regard to two non-functional properties: timeliness and overload detection. Timeliness is an important requirement to ensure user interface responsiveness and the smoothness of multimedia operations. Overload can occur when applications ask for more computation time than the machine can offer. Interactive systems have to handle overload situations dynamically at runtime. ATLAS provides timely service to applications, accessible through an easy-to-use interface. Deadlines specify timing requirements, workload metrics describe jobs. ATLAS employs machine learning to predict job execution times. Deadline misses are detected before they occur, so applications can react early.
