The use of deep learning for side channel analysis has shown a lot of success in recent years. Impressive results have been presented by many researchers. However, critics of this approach have voiced concerns about the ad hoc methodologies and bespoke neural network designs used in many presented approaches. This thesis first analyzes a possibility of generalizing the selection of neural network architecture for side channel analysis. Then, it presents a simple model for a multilayer perceptron network that does not need to be altered for different targets. Experiments are conducted on three different data sets; power consumption measurements of USIMs, far-field electromagnetic measurements of a Bluetooth device, and power consumption measurements of dedicated XMega victim boards. For each of these sets a model is presented with equivalent or better than state-of-the art results for secret key recovery. Training and testing are done on separate devices in each case. One of the models achieves a classification accuracy of 94.5% from a single measurement. Furthermore, the target and the training device do not even share the same printed circuit board layout. Another model achieves a 47.4% classification accuracy from measurements captured in a manner that is possible in a real-world attack. The thesis also investigates if three different numerical ways of determining the leakage point in unprotected implementations of AES agree. The tests are applied to all three data sets. Finally the thesis evaluates whether the popular transformer architecture is beneficial for side channel analysis. / Användande av djupinlärning för sidokanalsanalys har haft stora framgångar de senaste åren. Imponerande resultat har presenterats av många forskare. Men kritiker av detta tillvägagångssätt har uttryckt oro över att metoderna är ad hoc, och att specialanpassade neuronnätverksdesigner används i många presenterade rapporter. Detta examensarbete undersöker först möjligheten att generalisera valet av neuronnätverksarkitekturer för sidokanalsanalys. Sedan presenterar jag en enkel modell för ett multilayer perceptron-nätverk som inte behöver anpassas för olika enheter. Experiment genomförs på tre olika dataset; strömförbrukningsmätningar av USIMs, elektromagnetiska mätningar i fjärrfält av en Bluetooth-enhet, och strömförbrukningsmätningar av dedikerade XMega sidokanalsanalys-enheter. För var och en av dessa enheter presenteras en modell med likvärdiga eller bättre resultat som tidigare publicerad forskning. Träning och testning görs på separata enheter i varje fall. En av modellerna uppnår en klassificeringsprecision på 94,5% från en enda mätning. Dessutom delar attackenheten och träningsenheten inte ens samma kretskortslayout. En annan modell uppnår en klassificeringsprecision på 47,4% från mätningar som gjorts på ett sätt som ar realistiskt i en verklig attack. Examensarbetet undersöker också om tre olika numeriska sätt att bestämma läckagepunkten i oskyddade implementeringar av AES överensstämmer. Testerna tillämpas på alla tre dataset. Slutligen utvärderar examensarbetet om den populära transformer-arkitekturen ar passande för sidokanalsanalys.

No / The Silences Framework as a tool for exploring marginalised perspectives The Silences Framework was devised for use as a vehicle for exposing additional viewpoints in studies revolving around sensitive subjects and marginalised perspectives. Cyril’s presentation conveys the use of The Silences Framework in the provision of a nurse-led intervention for custodial community based ex-offenders. ‘Screaming Silences’ as exposed were located in the subjective experiences of ex-offenders known as the ‘listener’ and the social and personal context in which their experiences occurred. Crucially, The Silences Framework as used sought to acknowledge and redress the balance of power relating to ‘what and whose’ experience count in a research study. Epistemologically, the generation of knowledge using the framework necessitated an anti-essentialist perspective which was interpretive in nature. Thus, the intent was to arrive at what constitutes as truth from the lived experiences of the individuals researched. It is hoped that this presentation will facilitate understanding by unravelling the process of using The Silences Framework to underpin applied research and concurrently contribute to the wider use of the framework in research with other marginalised groups.

No / The current context of offender health in England and Wales indicates that the health needs of ex-offenders are significantly greater than those of the general population with a lack of equity existing between need and supply. The study presented herein is aimed at mapping the ex-offender health pathway towards identifying “touch points” in the community for the delivery of nurse-led interventions. The study was underpinned by the “Silences Framework” which enabled the study to gain theoretically by situating power with ex-offenders. A total of 26 respondents were ranked on the basis of poor health with those scoring the lowest and confirming their ranking through a confirmation of a health condition selected as cases and interviewed over the course of 6 months. These interview narratives were validated by interviewing individuals in the professional networks of ex-offenders and were analysed using the inductive qualitative thematic approach. The study uncovered that ex-offenders were not prepared in prison for the continuity in access to health care in the community on release. Ex-offender’s on-release preparation did not enquire as a matter of procedure on whether an offender was registered with a General Practitioner (GP) or had the agency to register self with a practice on release. Postrelease, the study uncovered a disparity between services, which address the physical health needs of ex-offenders and those which address their mental and substance misuse health needs. Finally, the study identified the site of postrelease supervision as the “touch point,” where a nurse-led intervention could be delivered.

No / The Silences Framework and its underpinning concept of ‘Screaming Silences’ was originally presented with the invitation for further peer review and utilisation in other contexts in order to test its usefulness and enable critique by a wider audience. This paper reports the use of the framework in a study researching nurse-led interventions for released ex-offenders. Screaming Silences were situated in how an issue, as experienced by ex-offenders, screams out to them in relation to their health and its impact on their reality while remaining silent in the consciousness of society and the application of practice. In addressing these Screaming Silences, we associated the Silences Framework within marginal discourses as they are less prioritised by policy and frequently positioned as far removed from what society considers as normal. Screaming Silences were situated in the subjective experiences of ex-offenders known as the ‘listener’ and the social and personal context in which these experiences occurred. We affirmed that the framework is ideally suited for researching issues which are under-researched, silent from policy discourse and excluded from practice, as it is oriented towards exploring individual experiences by valuing individual interpretations of events.

Dans les centres d’hébergement et de soins de longue durée (CHSLD), jusqu’à 80 % des personnes admises vivent avec une démence (Conseil des aînés, 2007). Parmi ces personnes âgées, plusieurs crient. Ce comportement a fait l’objet de quelques études, mais ces études ne fournissent pas une compréhension des sens de ces cris qui pourrait orienter le choix d’interventions face à ces personnes et leur entourage. À l’aide de la perspective infirmière de Leininger (2001) et de la théorie de la communication et des interactions à l’intérieur de triades d’Adams et Gardiner (2005), le but de cette étude était de décrire les sens des cris de personnes âgées vivant avec une démence et les facteurs les influençant en tenant compte de la perspective des personnes âgées, de leurs aidants familiaux et de leurs soignants. Pour atteindre ce but, l’ethnographie critique a été choisie comme méthode. L’étude s’est découlée dans un CHSLD au sein duquel sept triades, composées de personnes âgées vivant avec une démence qui crient, d’aidants familiaux principaux et de soignants, ont été recrutées selon un échantillonnage théorique. Diverses méthodes de collecte des données ont été utilisées dont l’observation des personnes âgées et du milieu et des entrevues semi-dirigées auprès des aidants et soignants. L’analyse des données a été effectuée à l’aide des quatre approches proposées par Spradley (1979) soit l’analyse : des domaines, taxonomique, componentielle et thématique. Les résultats ont permis d’identifier des thèmes sur les sens des cris et sur les facteurs influençant ceux-ci. Les cris peuvent avoir pour sens la vulnérabilité, la souffrance et la perte de sens vécues par la personne âgée. Ce comportement peut aussi indiquer diverses finalités, par exemple l’expression d’insatisfactions ou d’émotions. Ces finalités peuvent être distinguées à partir de critères de modulation tels que la prévisibilité des cris ou un faciès émotif. Par ailleurs, divers aspects rendent les sens des cris singuliers. La stabilité et la flexibilité dans la façon d’organiser les soins ainsi que l’effet réciproque entre les personnes âgées qui crient et les autres personnes dans le CHSLD se sont dégagées comme étant des facteurs qui influencent les sens des cris. Il s’est aussi révélé que les cris de chaque personne âgée peuvent être considérés comme un langage unique que les aidants et les soignants sont en mesure d’apprendre et qui influence l’interprétation des sens des cris. L’accompagnement de la personne âgée, en tenant compte de ses volontés, ses besoins et de sa personnalité, les fluctuations dans les relations de pouvoir au sein des triades personnes âgées-aidants-soignants et les sentiments d’impuissance et de culpabilité des aidants et des soignants sont d’autres facteurs qui influencent les cris. Les connaissances découlant de cette étude augmentent la compréhension sur les sens des cris des personnes âgées vivant avec une démence. Elles ont des implications pour les divers champs d’activités des infirmières et qui pourront contribuer à offrir des soins culturellement cohérents et caring pour les personnes âgées vivant avec une démence et leur entourage. / Eighty percent of people admitted in nursing homes live with dementia (Conseil des aînés, 2007). Many of these elderly persons scream. Research on this population does not provide a useful basis for understanding this behavior which would enable to guide the choice of appropriate interventions to help the elderly and the people who hear them. The purpose of this research was to describe –with the help of elderly persons, their family and their professional caregivers– the meanings of screams in the elderly with dementia and their influencing factors, using Leininger’s (2001) nursing perspective and Adams and Gardiner’s (2005) theory of communication and interaction within dementia care triads. Critical ethnography was selected as the research design. Seven triads –composed of elderly persons with dementia that scream, primary family caregivers, and formal caregivers– were recruited from a nursing home according to a theoretical sampling procedure. Various data collection methods were used, particularly, the observation of elderly persons and their environment as well as semi-structured interviews with their family and formal caregivers. Spradley’s (1979) four types of ethnographic analysis: domains, taxonomic, componential and themes analysis were used. The results lead to emergent themes on the meanings of screams and on their influencing factors. The meanings of screams can be related to the vulnerability, suffering, and loss of meaning experienced by the elderly. This behavior can also represent various final outcomes, for example, the expression of dissatisfaction or of emotions. These outcomes can be differentiated by modulation criteria such as predictability of screams or emotional facial expressions. Various aspects of the meanings of screams make them singular. Some factors that influence the meanings of screams are the stability and flexibility of nursing care and the effect that the elderly who scream and the persons in the nursing home surrounding them have on each other. The screams of each person also prove to be a unique language that can be learned by family and formal caregivers which can in turn change the interpretation of the screams. Other influencing factors are the respect of the wishes, needs, and personality of the elderly person, fluctuations in power relations within the elderly-family-caregivers triads and feelings of powerlessness and guilt in family and formal caregivers. Knowledge generated by this study increases our understanding on the meanings of screams in elderly persons with dementia. It has implications for research, education, clinical practice and management that could contribute to caring and culturally congruent care for elderly persons with dementia and the people around them.

Thesis (MA (English))--University of Stellenbosch, 2010. / ENGLISH ABSTRACT: This thesis explores masculinity and sexuality, hegemonic and “deviant” in the nation state of the old apartheid South Africa, by addressing aspects of fatherhood, boyhood and motherhood in white, predominantly Afrikaans family narratives. In doing this, I explore the ways in which the young boys in texts such as The Smell of Apples (1995), by Mark Behr, and moffie (2006), by André Carl van der Merwe, are systematically groomed to become the ideal stereotype of masculinity at the time: rugged, intelligent, successful and heterosexual. The main focus of this thesis is to explore the ideologies inherent in constructing the white, Afrikaner man, his woman and their family. This will be done with specific reference to the time frame between the early 1970s to the fall of the apartheid regime in the early 1990s, focussing on the young white boys who are sent to do military training and oftentimes, a stint on the border between Angola and the then South-West Africa, in order to keep the so-called threat of communism at bay. I explore what happens when this white-centred patriarchal hegemony is broken down, threatened or resisted when “deviance” in the form of homosexuality occurs. A second focus of this thesis is that of “deviance” in the army. I analyse “deviance” in three novels, moffie (2006) by André Carl van der Merwe, The Beautiful Screaming of Pigs (1991) by Damon Galgut and Kings of the Water (2009) by Mark Behr. These novels foreground “deviance” and I make use of them in exploring the punishment, or “consequences” of being homosexual or “deviant” in the highly masculine environs of the South African National Defence Force (SANDF) army. I also examine the muted yet, I argue, resistant voices of female characters in these novels. This thesis concludes by briefly noting the aftermath of this war, the after-effects of a white, hegemonic, conservative ruling party at the helm of a divided, war-faring country on its soldiers, who are now middle-aged men. / AFRIKAANSE OPSOMMING: Hierdie tesis ondersoek manlikheid en seksualiteit, hegemonie en “afwykings” in die staat van ou apartheid Suid-Afrika deur te verwys na aspekte van vaderskap, seunwees en moederskap in blanke, oorwegend Afrikaanse gesinsvertellings. Eerstens sal daar ondersoek ingestel word na die wyses waarop jong seuns in tekste soos The Smell of Apples (1995) deur Mark Behr en moffie (2006) deur André Carl van der Merwe stelselmatig gekweek word tot die ideale stereotipe van manlikheid in die era: ongetem, intelligent, suksesvol en heteroseksueel. Die hoofklem van hierdie tesis is om die denkwyses onderliggend aan die konstruksie van die blanke Afrikaner man, sy vrou en hulle gesin, te verken. Dit sal bewerkstellig word deur na die tydperk vanaf die vroeë 1970s tot en met die ondergang van die apartheidsbewind in die vroeë 1990s te verwys, met spesifieke klem op jeugdige blanke seuns wat gestuur is vir militêre opleiding en dikwels ook diensplig aan die grens tussen Angola en destydse Suid-Wes Afrika om die oënskynlike kommunistiese aanslag af te weer. Daar word verken wat plaasvind wanneer hierdie blank-gesentreerde, patriargale oorwig afgebreek, bedreig of teengestaan word deur “afwykings” soos die voorkoms van homoseksualiteit. ‘n Tweede fokuspunt van hierdie tesis is die “afwykings” in die weermag. Die volgende drie “afwykingsromans” word ontleed: moffie (2006), The Beautiful Screaming of Pigs (1991) deur Damon Galgut en Kings of the Water (2009) deur Mark Behr. Hierdie romans ondervang die idee van “afwykings” en word gebruik in die ondersoek na die straf of gevolge van homoseksueel of “afwykend” wees in die uitsluitlik manlike omgewing geskep deur die SANW-opleiding. Daar word ook ondersoek ingestel na die stilgemaakte; dog, soos aangetoon word, versettende stemme van vroulike karakters in die romans. Hierdie tesis sluit af deur vlugtig te verwys na die nasleep van die oorlog en die gevolge van ’n blanke, heersende, konserwatiewe party aan die stuur van ’n verdeelde, oorlogvoerende land op sy soldate wat tans middeljarige mans is.

The main topic of this diploma thesis resides in the comparison of the expressionist painting and the existential literature in connection with the motif of screaming. Despite the temporal and geographical distance of the two artistic movements (we are focused more profoundly in the German and Austrian expressionist painting, while the main literary work of this thesis, the existential novel The Fall comes from the great mind of a French writer, Albert Camus), the research aspires to prove the interconnection of the two movements and their common tendencies, based on the analyses of chosen themes, motifs, technics, and structure. We propose the motif of screaming as the main part of the comparison, as it constitutes an essential axis of the occidental art, as well as the crucial contact point between Expressionism and Existentialism. In spite of the bountifulness of the various interpretations this motif offers, we have chosen only selected ideas and concepts. As far as the formal structure is concerned, the work is divided into three chapters, where the first two are focused on the origins, a brief characterization of the main point of the two esthetics. Furthermore, they describe their related counterparts of the visual arts and literature (the Expressionist literature and Existential painting...
