Sistema de bloqueio de computadores
Mestrado em Engenharia de Computadores e TelemáticaThe use of multiple computing devices per person is increasing more and more. Nowadays is normal that mobile devices like smartphones, tablets and laptops are present in the everyday life of a single person and in many cases people use these devices to perform important operations related with their professional life. This also presents a problem, as these devices come with the user in everyday life and the fact that often they have a high monetary value means that these devices are susceptible to theft. This thesis introduces a computer locking system that distinguishes itself from existing similar systems because (i) it is designed to work independently of the Operating System(s) installed on the laptop or mobile device, (ii) depends on a firrmware driver that implements the lock operation making it resistant to storage device formats or any other attack that uses software operations. It is also explored the operation of a device that has a firrmware that follows the Unified Extensible Firmware Interface (UEFI) specification as well as the development of drivers for this type of firrmware. It was also developed a security protocol and various cryptographic techniques where explored and implemented.O uso de vários dispositivos computacionais por pessoa está a aumentar cada vez mais. Hoje em dia é normal dispositivos móveis como o smartphone, tablet e computador portátil estarem presentes no quotidiano das pessoas e em muitos casos as pessoas necessitam de realizar tarefas na sua vida profissional nestes dispositivos. Isto apresenta também um problema, como estes dispositivos acompanham o utilizador no dia a dia e pelo facto de muitas vezes terem um valor monetário elevado faz com que estes dispositivos sejam suscetíveis a roubos. Esta tese introduz um sistema de bloqueio de computadores que se distingue dos sistemas similares existentes porque, (i) _e desenhado para funcionar independentemente do(s) sistema(s) operativo(s) instalado(s) no computador portátil ou no dispositivo móvel, (ii) depende de um driver do firrmware que concretiza a operação de bloqueio fazendo com que seja resistente contra formatação do dispositivo de armazenamento ou qualquer outro ataque que tenho por base a utilização de software. É explorado então o funcionamento de um dispositivo que tenha um firmware que respeita a especificação Unfied Extensible Firmware Interface (UEFI) assim como a programação de drivers para este tipo de firmware. Foi também desenvolvido um protocolo
de segurança e são exploradas várias técnicas criptográficas passiveis de serem implementadas
Examples of works to practice staccato technique in clarinet instrument
Klarnetin staccato tekniğini güçlendirme aşamaları eser çalışmalarıyla uygulanmıştır. Staccato
geçişlerini hızlandıracak ritim ve nüans çalışmalarına yer verilmiştir. Çalışmanın en önemli amacı
sadece staccato çalışması değil parmak-dilin eş zamanlı uyumunun hassasiyeti üzerinde de
durulmasıdır. Staccato çalışmalarını daha verimli hale getirmek için eser çalışmasının içinde etüt
çalışmasına da yer verilmiştir. Çalışmaların üzerinde titizlikle durulması staccato çalışmasının ilham
verici etkisi ile müzikal kimliğe yeni bir boyut kazandırmıştır. Sekiz özgün eser çalışmasının her
aşaması anlatılmıştır. Her aşamanın bir sonraki performans ve tekniği güçlendirmesi esas alınmıştır.
Bu çalışmada staccato tekniğinin hangi alanlarda kullanıldığı, nasıl sonuçlar elde edildiği bilgisine
yer verilmiştir. Notaların parmak ve dil uyumu ile nasıl şekilleneceği ve nasıl bir çalışma disiplini
içinde gerçekleşeceği planlanmıştır. Kamış-nota-diyafram-parmak-dil-nüans ve disiplin
kavramlarının staccato tekniğinde ayrılmaz bir bütün olduğu saptanmıştır. Araştırmada literatür
taraması yapılarak staccato ile ilgili çalışmalar taranmıştır. Tarama sonucunda klarnet tekniğin de
kullanılan staccato eser çalışmasının az olduğu tespit edilmiştir. Metot taramasında da etüt
çalışmasının daha çok olduğu saptanmıştır. Böylelikle klarnetin staccato tekniğini hızlandırma ve
güçlendirme çalışmaları sunulmuştur. Staccato etüt çalışmaları yapılırken, araya eser çalışmasının
girmesi beyni rahatlattığı ve istekliliği daha arttırdığı gözlemlenmiştir. Staccato çalışmasını yaparken
doğru bir kamış seçimi üzerinde de durulmuştur. Staccato tekniğini doğru çalışmak için doğru bir
kamışın dil hızını arttırdığı saptanmıştır. Doğru bir kamış seçimi kamıştan rahat ses çıkmasına
bağlıdır. Kamış, dil atma gücünü vermiyorsa daha doğru bir kamış seçiminin yapılması gerekliliği
vurgulanmıştır. Staccato çalışmalarında baştan sona bir eseri yorumlamak zor olabilir. Bu açıdan
çalışma, verilen müzikal nüanslara uymanın, dil atış performansını rahatlattığını ortaya koymuştur.
Gelecek nesillere edinilen bilgi ve birikimlerin aktarılması ve geliştirici olması teşvik edilmiştir.
Çıkacak eserlerin nasıl çözüleceği, staccato tekniğinin nasıl üstesinden gelinebileceği anlatılmıştır.
Staccato tekniğinin daha kısa sürede çözüme kavuşturulması amaç edinilmiştir. Parmakların
yerlerini öğrettiğimiz kadar belleğimize de çalışmaların kaydedilmesi önemlidir. Gösterilen azmin ve
sabrın sonucu olarak ortaya çıkan yapıt başarıyı daha da yukarı seviyelere çıkaracaktır
Transformation of the business model to establish sustainable value in the consumer durables super store industry of Sri Lanka
The business model of an organization, operates as the fundamental blue print of the planning process, which shapes the nature of the strategies executed during the course of operation. These strategies in turn are responsible for the value creation or value erosion that takes place during the operation of the organization determining its sustainability, and in a broader context the sustainability of the industry. The research is done for the Consumer Durables Super Store (CDSS) industry of Sri Lanka concerning the existing business model, the value erosion occurring as a result of it and the risk it carries to the sustainability of the industry. The theoretical aspect of the research to develop a relationship based business model was anchored on the understanding of existing frameworks relating to sustainable value and extracting relevant areas of each of these frameworks (alignment of value, transforming current strategies and service offerings to create sustainable value) to develop a suitable hybrid framework with modifications to the literature to suite the research context.Ten in-depth interviews with CDSS organizational representatives holding leadership, sales and marketing management positions, and two focus group sessions with fifty selected customers were conducted in a virtual environment due to the prevailing pandemic situation. The data collected were analyzed with NVIVO 12, with themes relevant to the research utilized as codes, giving a clear understanding over the buyer and seller purview on the themes of the research. The findings surfaced the value erosion caused due to the financially driven strategies originated from the transactional orientation of the existing business model. The theories adopted to construct the relationship oriented business model to rectify the value erosion taking place, based on sustainable value, value alignment and service offerings, were modified to incorporate ‘quality of trade’ to bridge the gap, leading towards the creation and delivery of sustainable value to the buyer-seller eco system of the industry

Co-design As Healing: Exploring The Experiences Of Participants Facing Mental Health Problems
This thesis is an exploration of the healing role of co-design in mental health. Although co-design projects conducted within mental health settings are rising, existing literature tends to focus on the object of design and its outcomes while the experiences of participants per se remain largely unexplored. The guiding research question of this study is not how we design things that improve mental health, but how co-designing, as an act, might do so.
The thesis presents two projects that were organized in collaboration with the mental health charity Islington Mind and the Psychosis Therapy Project (PTP) in London.
The project at Islington Mind used a structured design process inviting participants to design for wellbeing. A case study analysis provides insights on how participants were impacted, summarizing key challenges and opportunities.
The design at PTP worked towards creating a collective brief in an emergent fashion, finally culminating in a board game. The experiences of participants were explored through Interpretative Phenomenological Analysis (IPA), using semi-structured interview data. The analysis served to identify key themes characterising the experience of co-design such as contributing, connecting, thinking and intentioning. In addition, a mixed-methods analysis of questionnaires and interview data exploring participants' wellbeing, showed that all participants who engaged fairly consistently in the project improved after the project ended, although some participants' scores returned to baseline six months later.
Reflecting on both projects, an approach to facilitation within mental health is outlined, detailing how the dimensions of weaving and layered participation, nurturing mattering and facilitating attitudes interlace. This contribution raises awareness of tacit dimensions in the practice of facilitation, articulating the nuances of how to encourage and sustain meaningful and ethical engagement and offering insights into a range of tools. It highlights the importance of remaining reflexive in relation to attitudes and emotions and discusses practical methodological and ethical challenges and ways to resolve them which can be of benefit to researchers embarking on a similar journey.
The thesis also offers detailed insights on how methodologies from different fields were integrated into a whole, arguing for transparency and reflexivity about epistemological assumptions, and how underlying paradigms shift in an interdisciplinary context.
Based on the overall findings, the thesis makes a case for considering design as healing (or a designerly way of healing), highlighting implications at a systems, social and individual level. It makes an original contribution to our understanding of design, highlighting its healing character, and proposes a new way to support mental health. The participants in this study not only had increased their own wellbeing through co-designing, but were also empowered and contributed towards healing the world. Hence, the thesis argues for a unique, holistic perspective of design and mental health, recognizing the interconnectedness of the individual, social and systemic dimensions of the healing processes that are ignited

The interpretation of Islam and nationalism by the elite through the English language media in Pakistan.
The media is constructed and interpreted through what people 'know'. That knowledge is, forthe most part, created through day to day experiences. In Pakistan, Islam and nationalism aretwo components of this social knowledge which are intrinsically tied to the experiences of thePakistani people. Censorship and selection are means through which this knowledge isarticulated and interpreted.General conceptions of partially shared large scale bodies of knowledge and ideas reinforce,and are reinforced by, general medium of mass communication: the print and electronic media.Focusing on the govermnent, media institutions and Pakistani elites, I describe and analyse thedifferent, sometimes conflicting, interpretations of Islam and Pakistani nationalism manifest inand through media productions presented in Pakistan.The media means many things, not least of which is power. It is the media as a source ofpower that is so frequently controlled, directed and manipulated. The terminology may beslightly different according to the context within which one is talking - propaganda, selection,etc. - but ultimately it comes down to the same thing - censorship. Each of the three groups:government, media institutions and Pakistani elites - have the power to interpret and censormedia content and consideration must be taken of each of the other power holders consequentlyrestricting the power of each group in relation to the other two. The processes of thismanipulation and their consequences form the major themes of this thesis
Management Matters : Organizational Storytelling within the Anthroposophical Society in Sweden
The Anthroposophical Society, founded by the Austrian polymath Rudolf Steiner, came to Sweden in 1913, but for the generation of present-day Swedish Anthroposophists whose voices are heard in this study, the great flowering of the movement occurred in the second half of the twentieth century. The movement had by then expanded into a large milieu with many largely independent enterprises and institutions, from the formal organization itself, to various schools, farms, shops, medical facilities, etc., all based on interpretations of Steiner’s legacy. Since then, many members of the movement feel, there has been a decline.
A movement of this size and complexity can be seen as a large organization with a corporate-like structure. Taking its point of departure in ideas from the vast field of organization studies, and specifically in the study of storytelling as part of the creation of a corporate culture where many voices and many perspectives co-exist, this study investigates how Anthroposophists in Sweden, both rank and-file members and some who served in leadership positions, tell the story of the putative Golden Age, decline, and projected future of Anthroposophy in Sweden. Twenty-eight interviews were collected, recurrent themes identified, and the plots of the various individual stories analyzed by means of a version of the actantial model developed by the semioticist Algirdas Greimas.
The basic storyline, of which the interviewees’ individual stories constitute variations, is that the Golden Age, when charismatic leaders could draw crowds of enthusiastic young people and a vibrant Anthroposophical milieu was built up, came to an end with the demise of those leaders. The present, i.e., the time at which the interviews were conducted, is narratively framed as a period of sharp decline. The vistas for the future come across in most stories as quite bleak. An actantial analysis reveals that the past, an epoch that is on one hand held up as a shining example is on the other hand also described as a time characterized by innumerable problems and conflicts. Disagreement is rampant regarding the reasons for the current decline, and a vast number of problems are identified in the individual narratives. The future is for some interviewees impossible to speculate about, whereas others have specific suggestions for change. These suggestions, when held up against each other, show that there is no unified vision of what the necessary changes might be or who must bring them about.
The interviewees agree that Anthroposophy plays a vital role as a spiritual path. When asked how they would describe Anthroposophy and what it more specifically can offer, answers diverge, but substantive descriptions of core concepts or practices are rarely alluded to. Rather, their explanations of what Anthroposophy is are in almost all cases metaphorical or negative, i.e., they represent Anthroposophy as elusive or undefinable. Interviewees can suggest that the lack of a clear Anthroposophical “brand” is a major reason for its current perceived crisis. An analysis of the ways in which Rudolf Steiner is portrayed in the interview material shows that there are a variety of descriptions of him rather than a unified representation of a charismatic leader that members can rally around. This, the study suggests, is because four different forms of charisma can be distinguished on theoretical grounds, and the particular form that permeates the narratives collected for this study does not readily support the dissemination of a centralized, dominant narrative.Antroposofiska Sällskapet, grundat av österrikaren Rudolf Steiner, kom till Sverige redan i 1913, men för den generation av nutida svenska antroposofer vars röster hörs i denna studie inträffade rörelsens stora blomstringstid först under nittonhundratalets andra hälft. Vid det laget hade rörelsen expanderat och blivit till en omfattande miljö med många stort sett oberoende institutioner och verksamheter, från själva det Antroposofiska Sällskapet i strikt mening till olika skolor, lantbruk, butiker, kliniker, osv., som alla byggde på tolkningar av arvet efter Steiner. Många medlemmar i rörelsen menar att det sedan dess har skett en nedgång.
En rörelse med den storlek och komplexitet som det rör sig om i det aktuella fallet kan betraktas som en organisation med en företagsliknande struktur. Denna studie tar därför sin utgångspunkt i ett organisationsteoretiskt perspektiv, i synnerhet i den gren av organisationsteorin som studerar berättande som ett led i hur en organisationskultur med många samexisterande röster skapas. I det aktuella fallet handlar det om berättelser som antroposofer i Sverige, både vanliga medlemmar och personer i ledarställning, framför om den blomstringstid de menar rörelsen en gång hade, den nedgång de säger sig uppleva och den framtid de föreställer sig att antroposofin i Sverige kommer att möta. Tjugoåtta intervjuer genomfördes och de berättelser som förmedlas i dessa intervjuer analyserades med hjälp av en variant av den aktantmodell som utvecklats av semiotikern Algirdas Greimas.
Den grundläggande handling man återfinner i intervjupersonernas olika berättelser är att blomstringstiden var en guldålder då karismatiska ledare kunde samla stora grupper av entusiastiska ungdomar och en levande antroposofisk miljö byggdes upp, men att denna guldålder upphörde när ledarna gick ur tiden. Nuet, alltså den tid då intervjuerna genomfördes, beskrivs i berättelserna som en tid av förfall. Framtidsutsikterna som målas upp i de flesta berättelser är dystra. Aktantanalysen visar att berättelserna om det förflutna både beskriver denna tid i mycket positiva termer och nämner otaliga problem och konflikter. Nuets påstådda förfall återkommer i de flesta berättelser, men åsikterna går vitt isär när det gäller vad nutidens problem är och vad som orsakat dem. Framtiden beskrivs av vissa intervjupersoner som omöjlig att spekulera närmare om, medan andra har specifika förslag till förändringar. Sammantaget visar analysen att det saknas en enhetlig föreställning om vad som behöver göras för att lösa rörelsens problem och vem som ska ta ansvar för dessa förändringar.
Intervjupersonerna är eniga om att antroposofin spelar en viktig roll. Frågan hur de skulle beskriva antroposofin och vad den har att erbjuda besvaras på olika sätt, men sällan i termer av konkreta beskrivningar av för antroposofin centrala föreställningar eller praktiker. Tendensen är snarare att svara i metaforiska eller negativa termer, alltså genom att berätta att de menar att antroposofin inte går att definiera. Samtidigt kan intervjupersonerna förklara att bristen på en tydlig antroposofisk identitet är ett huvudskäl till vad de ser som rörelsens nuvarande kris. En analys av de sätt på vilka Rudolf Steiner beskrivs i intervjumaterialet visar att det också finns en rad divergerande uppfattningar av honom snarare än en sammanhållen beskrivning av en karismatisk ledare som medlemmarna kan samlas kring. Studien konkluderar att karisma på teoretiska grunder kan delas in i fyra olika typer, och att den specifika form av karisma som intervjuerna återspeglar inte harmonierar särskilt väl med spridandet av en centralt utformad dominerande berättelse
CRUSOE: A Toolset for Cyber Situational Awareness and Decision Support in Incident Handling
The growing size and complexity of today’s computer network make it hard to achieve and maintain so-called cyber situational awareness, i.e., the ability to perceive and comprehend the cyber environment and be able to project the situation in the near future. Namely, the personnel of cybersecurity incident response teams or security operation centers should be aware of the security situation in the network to effectively prevent or mitigate cyber attacks and avoid mistakes in the process. In this paper, we present a toolset for achieving cyber situational awareness in a large and heterogeneous environment. Our goal is to support cybersecurity teams in iterating through the OODA loop (Observe, Orient, Decide, Act). We designed tools to help the operator make informed decisions in incident handling and response for each phase of the cycle. The Observe phase builds on common tools for active and passive network monitoring and vulnerability assessment. In the Orient phase, the data on the network are structured and presented in a comprehensible and visually appealing manner. The Decide phase opens opportunities for decision-support systems, in our case, a recommender system that suggests the most resilient configuration of the critical infrastructure. Finally, the Act phase is supported by a service that orchestrates network security tools and allows for prompt mitigation actions. Finally, we present lessons learned from the deployment of the toolset in the campus network and the results of a user evaluation study
The Allocation of Intellectual Property Rights Between Employers and Employees in the United Kingdom
The subject of this thesis is the allocation of intellectual property rights between employers and employees: a legal, a social, a psychological and an economic phenomenon. Chapter 4 sets out the basic methodological framework adopted in this thesis and explains what is intellectual property. Chapter 5 examines the economic problems attached to the creation and exploitation of intellectual property rights. Chapter 6 examines the subject of industrial relations and explains why employee creators do not obtain adequate protection for themselves through the medium of collective bargaining. Chapter 7 examines the psychological nature of inventing. Chapter 8 looks at the nature of awards given to employee creators by their employers; the theoretical and practical 1 basis for the making of awards to inventors is also discussed, and objections to the establishment of a statutory award scheme evaluated. Chapter 9 introduces the layman to the law of contract, the doctrine of restraint of trade, and the employee's difficulty in altering the terms of a standard employment contract. Chapter 10 is a study of the allocation of patent rights between inventors and their employers. British law is contrasted with the American law, which provides an alternative measure for protecting patent rights. Chapter 11 looks at the laws relating to confidential information. Chapter 14 explains the different problems faced by English and American Courts when allocating rights in industrial designs. Chapter 16 explores the allocation of moral rights to employers and employees, contrasting the Anglo-American tradition with that of the European civil law. Chapter 17 seeks to evaluate the remedies provided by equity as a potential means of rewarding or compensating an employee for work done outside his contract of employment. Chapter 18 examines current proposals for law reform
Building a Generic Value Creation Model For the Sri Lankan National Education System
This research was an attempt to build a generic value creation model architecture which can be used by any organisation without business v. public or profit v non-profit differences, by way of: a synthesis of literature in 6 streams of management related to value creation; operationalise it using data collected through an exploratory study in the System of General School Education in Sri Lanka; and, test the operationalised model in the same context through a confirmatory study.
The study was a mixed-method one, using in its exploratory phase interviews as its data collection instrument, and in its subsequent confirmatory phase, questionnaires as its data collection instruments. Data analysis methodologies used to test hypotheses were structured equation modelling and multiple regression analysis.
The operationalisation validated the model building assumptions, and the final research results showed that the proposed model can be used in a national-scale public education context to measure value creation
