Full textAbstract:
The methods used to store data on DVD-R discs have been proven to work over the last 15 years. However, there has been a growing concern that these discs will be outlasted by the paper records they were meant to replace. The data on a DVD-R is stored as optical contrasts which have the potential to be misread and even damaged. This damage may occur either on the surface or internally to the disc, especially on the recording layer itself. The literature is saturated with studies attempting to determine the time period in which discs may fail and what the general signs of the degradation are, but almost all fail to determine the fundamental causes of DVD degradation. In particular, the exact connection between the physical state of the disc and its digital errors is undetermined. This study undertook to develop a framework to study and understand this relationship. The study also consisted of a characterization validation experiment involving several brands of DVD-Rs. The framework constructed during the course of the research included several tools. Due to the lack of an existing tool able to aggregate the gathered data, a specialized software program, called SectorDraw, was developed. In the course of this study, this software tool was validated. Additionally, it was discovered that physical defects should be evaluated and characterized by using a process of visual inspection, microscope examination, and measurements. Although not all relationships between physical defects and digital errors were explored, the study established the fact that defects can directly cause bursts of digital errors. This indicated that there was a connection between physical defects and digital errors. It was also found that physical defects developed over time after treatments of artificial aging. The developed framework was established as viable for future research to study specific relationships between physical defects and digital errors.

Full textAbstract:
Music video is an intriguing genre of television due to the fact that music drives the images and ideas found in numerous and varied examples of the form. Pre-recorded pieces of pop music are visually written upon in a palimpsest manner, resulting in an immediate and entertaining synchronisation of sound and vision. Ever since the popularity of MTV in the early 1980s, music video has been a persistent fixture in academic discussion, most notably in the work of writers like E. Ann Kaplan, Simon Frith and Andrew Goodwin. What has been of major interest to such cultural scholars is the fact that music video was designed as a promotional tool in their inception, supporting album sales and increasing the stardom of the featured recording artists. Authorship in music video studies has been traditionally kept to the representation of music stars, how they incorporate post-modern references and touch upon wider cultural themes (the Marilyn Monroe pastiche for the Madonna video, Material Girl (1985) for instance). What has not been greatly discussed is the contribution of music video directors, and the reason for that is the target audience for music videos are teenagers, who respond more to the presence of the singer or the band than the unknown figure of the director, a view that is also adhered to by music television channels like MTV.

Previous issue date: 2006-06-05The images (painting, photograph, cinema, etc.) had always been constructed for specific ends and through the mediation between us (spectators) and the reality, it was possible to represent the world that surrounded us. With the arrival of the graphical computation and new digital formats, the image acquires new abilities. To argue the properties and trends of the digital image are extremely excellent aspects for the development of new systems, processes and theories in communication. When it is conceived and allied to the interface concept, this image can be transformed into image-interface, thus multiplying, its characteristics and potentialities. A good platform to think the digital medias as inhabitable medias and the parameters to argue the transformation of the image in image interface is the digital video disc, because it possess technical characteristics witch allows the mapping of information and the storage of great amount of data. The objective of this research is to argue and apply the image-interface concepts, elaborated mainly by Peter Weibel, Lev Manovich and Mark Hansen, in the DVDs and the new formats of the digital communication like the Internet and electronic panels. The interfaces analysis of commercial and experimental DVDs and DVD Roms will allow to understand the current limitations in the interfaces´exploration and argue if it is possible to extend its resources and to use these concepts in the scope of a market culture, which a media quickly is substituted by another one before they deplete its possibilities
As imagens (pintura, fotografia, cinema, etc.) sempre foram construídas para fins específicos e através da mediação entre nós (espectadores) e a realidade, foi possível representar o mundo que nos cercava. Com a chegada da computação gráfica e de novos formatos digitais, a imagem adquire novas competências. Discutir as propriedades e tendências da imagem digital são aspectos extremamente relevantes para o desenvolvimento de novos sistemas, processos e teorias comunicacionais. Ao ser concebida e aliada ao conceito de interface, essa imagem pode ser transformada em imagem interface, multiplicando assim, suas características e potencialidades. Uma boa plataforma para pensar as mídias digitais e os parâmetros para discutir a transformação da imagem em imagem interface é o disco de vídeo digital, pois possui características técnicas que permitem o mapeamento de informações e o armazenamento de grande quantidade de dados. O objetivo desta pesquisa é discutir e aplicar os conceitos de imagem-interface, elaborados principalmente por Peter Weibel, Lev Manovich e Mark Hansen, no ambiente dos DVDs e dos novos formatos da comunicação digital, como a Internet e os painéis eletrônicos. A análise de interfaces de DVDs e DVD Roms comerciais e experimentais permitirá entender as limitações atuais na exploração da interface e interrogar se é possível ampliar seus recursos e se utilizar desse conceitos no âmbito de uma cultura de mercado, dentro da qual uma mídia é rapidamente substituída por outra antes que esgotem suas possibilidades

Full textAbstract:
This dissertation provides a comprehensive overview of the theory and practice of Dynamic Voltage/Frequency Scaling (DVFS) in the High Performance Computing (HPC) environment. We summarize the overall problem as follows: how can the same level of computational performance be achieved using less electrical power? Equivalently, how can computational performance be increased using the same amount of electrical power? In this dissertation we present performance and architecture models of DVFS as well as the Adagio runtime system. The performance model recasts the question as an optimization problem that we solve using linear programming, thus establishing a bound on potential energy savings. The architectural model provides a low-level explanation of how memory bus and CPU clock frequencies interact to determine execution time. Using insights provided from these models, we have designed and implemented the Adagio runtime system. This system realizes near-optimal energy savings on real-world scientific applications without the use of training runs or source code modification, and under the constraint that only negligible delay will be tolerated by the user. This work has opened up several new avenues of research, and we conclude by enumerating these.

Full textAbstract:
Recent increase in performance of High Performance Computing (HPC) systems has been followed by
even higher increase in power consumption. Power draw of modern supercomputers leads to very high
operating costs and reliability concerns. Furthermore, it has negative consequences on the environment.
Accordingly, over the last decade there have been many works dealing with power/energy management
in HPC systems.
Since CPUs accounts for a high portion of the total system power consumption, our work aims at CPU
power reduction. Dynamic Voltage Frequency Scaling (DVFS) is a widely used technique for CPU
power management. Running an application at lower frequency/voltage reduces its power
consumption. However, frequency scaling should be used carefully since it has negative effects on the
application performance.
We argue that the job scheduler level presents a good place for power management in an HPC center
having in mind that a parallel job scheduler has a global overview of the entire system. In this thesis we
propose power-aware parallel job scheduling policies where the scheduler determines the job CPU
frequency, besides the job execution order. Based on the goal, the proposed policies can be classified
into two groups: energy saving and power budgeting policies. The energy saving policies aim to reduce
CPU energy consumption with a minimal job performance penalty. The first of the energy saving
policies assigns the job frequency based on system utilization while the other makes job performance
predictions. While for less loaded workloads these policies achieve energy savings, highly loaded
workloads suffer from a substantial performance degradation because of higher job wait times due to
an increase in load caused by longer job run times. Our results show higher potential of the DVFS
technique when applied for power budgeting.
The second group of policies are policies for power constrained systems. In contrast to the systems
without a power limitation, in the case of a given power budget the DVFS technique even improves
overall job performance reducing the average job wait time. This comes from a lower job power
consumption that allows more jobs to run simultaneously. The first proposed policy from this group
assigns CPU frequency using the job predicted performance and current power draw of already running
jobs. The other power budgeting policy is based on an optimization problem which solution determines
the job execution order, as well as power distribution among jobs selected for execution. This policy
fully exploits available power and leads to further performance improvements.
The last contribution of the thesis is an analysis of the DVFS technique potential for energyperformance
trade-off in current and future HPC systems. Ongoing changes in technology decrease the
DVFS applicability for energy savings but the technique still reduces power consumption making it
useful for power constrained systems. In order to analyze DVFS potential, a model of frequency
scaling impact on MPI application execution time has been proposed and validated against
measurements on a large-scale system. This parametric analysis showed for which
application/platform characteristic, frequency scaling leads to energy savings.El aumento de rendimiento que han experimentado los sistemas de altas prestaciones ha venido acompañado de un aumento aún mayor en el consumo de energía. El consumo de los supercomputadores actuales implica unos costes muy altos de funcionamiento. Estos costes no tienen simplemente implicaciones a nivel económico sino también implicaciones en el medio ambiente. Dado la importancia del problema, en los últimos tiempos se han realizado importantes esfuerzos de investigación para atacar el problema de la gestión eficiente de la energía que consumen los sistemas de supercomputación. Dado que la CPU supone un alto porcentaje del consumo total de un sistema, nuestro trabajo se centra en la reducción y gestión eficiente de la energía consumida por la CPU. En concreto, esta tesis se centra en la viabilidad de realizar esta gestión mediante la técnica de Dynamic Voltage Frequency Scalingi (DVFS), una técnica ampliamente utilizada con el objetivo de reducir el consumo energético de la CPU. Sin embargo, esta técnica puede implicar una reducción en el rendimiento de las aplicaciones que se ejecutan, ya que implica una reducción de la frecuencia. Si tenemos en cuenta que el contexto de esta tesis son sistemas de alta prestaciones, minimizar el impacto en la pérdida de rendimiento será uno de nuestros objetivos. Sin embargo, en nuestro contexto, el rendimiento de un trabajo viene determinado por dos factores, tiempo de ejecución y tiempo de espera, por lo que habrá que considerar los dos componentes. Los sistemas de supercomputación suelen estar gestionados por sistemas de colas. Los trabajos, dependiendo de la política que se aplique y el estado del sistema, deberán esperar más o menos tiempo antes de ser ejecutado. Dado las características del sistema objetivo de esta tesis, nosotros consideramos que el Planificador de trabajo (o Job Scheduler), es el mejor componente del sistema para incluir la gestión de la energía ya que es el único punto donde se tiene una visión global de todo el sistema. En este trabajo de tesis proponemos un conjunto de políticas de planificación que considerarán el consumo energético como un recurso más. Estas políticas decidirán que trabajo ejecutar, el número de cpus asignadas y la lista de cpus (y nodos) sino también la frecuencia a la que estas cpus se ejecutarán. Estas políticas estarán orientadas a dos objetivos: reducir la energía total consumida por un conjunto de trabajos y controlar en consumo puntual de un conjunto puntual para evitar saturaciones del sistema en aquellos centros que puedan tener una capacidad limitada (permanente o puntual). El primer grupo de políticas intentará reducir el consumo total minimizando el impacto en el rendimiento. En este grupo encontramos una primera política que asigna la frecuencia de las cpus en función de la utilización del sistema y una segunda que calcula una estimación de la penalización que sufrirá el trabajo que va a empezar para decidir si reducir o no la frecuencia. Estas políticas han mostrado unos resultados aceptables con sistemas poco cargados, pero han mostrado unas pérdidas de rendimiento significativas cuando el sistema está muy cargado. Estas pérdidas de rendimiento no han sido a nivel de incremento significativo del tiempo de ejecución de los trabajos, pero sí de las métricas de rendimiento que incluyen el tiempo de espera de los trabajos (habituales en este contexto). El segundo grupo de políticas, orientadas a sistemas con limitaciones en cuanto a la potencia que pueden consumir, han mostrado un gran potencial utilizando DVFS como mecanismo de gestión. En este caso, comparado con un sistema que no incluya esta gestión, han demostrado mejoras en el rendimiento ya que permiten ejecutar más trabajos de forma simultánea, reduciendo significativamente el tiempo de espera de los trabajos. En este segundo grupo proponemos una política basada en el rendimiento del trabajo que se va a ejecutar y una segunda que considera la asignación de todos los recursos como un problema de optimización lineal. Esta última política es la contribución más importante de la tesis ya que demuestra un buen comportamiento en todos los casos evaluados. La última contribución de la tesis es un estudio del potencial de DVFS como técnica de gestión de la energía en un futuro próximo, en función de un estudio de las características de las aplicaciones, de la reducción de DVFS en el consumo de la CPU y del peso de la CPU dentro de todo el sistema. Este estudio indica que la capacidad de DVFS de ahorrar energía será limitado pero sigue mostrando un gran potencial de cara al control del consumo energético.

The purpose of this thesis is to seek answers to the questions how the sales in a photo shop can be affected by animated commercial presentations and what the costs of producing such presentations would be. The costs are calculated from three different scenarios. The presentations produced has been for one single camera model and for selected products within three product groups; binoculars, digital cameras and printed matters. The task has included image processing of self-shot and existing photos, as well as arranging and animating the photos together with texts and three-dimensional models of selected products. The content and proceedings for each product group is presented separately together with problems occurred during the production. Eventually, the result chapter presents the sales statistics and calculated costs.Detta examensarbetes syfte har varit att söka svar på frågorna om huruvida försäljningen i en fotobutik kan påverkas av rörliga reklampresentationer samt hur stor kostnaden skulle bli om arbetet utförts utanför universitetet. Kostnaderna har sedan beräknats utifrån tre olika tänkbara scenarion. Presentationerna som producerats har varit för en enskild kameramodell samt för utvalda produkter inom produktgrupperna kikare, kameror samt trycksaker. Arbetet har omfattat dels bildbehandling av egna och befintliga foton, dels disponering och animering av dessa foton tillsammans med textblock och animationer av tredimensionella modeller av vissa av produkterna. För varje produktgrupp redovisas innehåll och tillvägagångssätt tillsammans med problem som uppstått under produktionens gång. I resultatdelen redovisas sedan förändringen i försäljningen samt de beräknade kostnaderna med utgång från åtgången tid för respektive presentation.

Syftet med den här uppsatsen var att skapa underlag för ett nytt undervisningsmaterial för trafiklärare. Problemställningen var om DVD-skivan kunde vara ett nytt hjälpmedel för att underlätta för både elev och lärare i körkortsundervisningen. Ytterligare
problemställningar var.
Kan en DVD-instruktion underlätta elevens och trafiklärarens förmåga till att kunna göra en självvärdering? Kan en DVD-instruktion underlätta för eleven och trafikläraren att förstå målet med en övning? Tror eleven och trafikläraren ha sig nytta av en DVD-instruktion? Tror eleven och trafikläraren att en DVD-instruktion spar tid = mindre övningskörningstid? Vill eleven och trafikläraren att trafikläraren hellre demonstrerar en övning med egen körning istället för en DVD-instruktion? Upplever eleven och trafikläraren att en kördemonstration av trafikläraren tar tid av
elevens körlektion?
Utgångspunkten för uppsatsen var en bandad intervju och ett eget tillverkat filmmaterial som är överfördes till en DVD-skiva. Utifrån användningen av denna DVD-skiva har jag gjort en enkätundersökning med svarsalternativen ja och nej.
Det teoretiska perspektivet i den här uppsatsen var att med hjälp av enkäterna få svar som hade så stora variationer och mönster att de var lätta att tolka och förstå för att kunna ge svar på mina frågeställningar.
Det viktigaste resultatet från studien är att DVD-instruktionen var till hjälp för eleven att kunna göra sin självvärdering och till hjälp för trafikläraren att förtydliga en kördemonstration. Den visar också på att både elever och trafiklärare tycker att den många gånger kan ersätta en kördemonstration. Den viktigaste slutsatsen av forskningsstudien var att det finns ett behov av ett nytt verktyg som DVD-instruktion i körkortsutbildningen.

Full textAbstract:
The purpose of this thesis is to analyze DVD covers for the genre romantic comedy from the 2000s as a way to obtain patterns and codes provided by the genre. The theoretical framework consists of previous research that analyzed various posters, theories about semiotics, genre, and visual rhetoric. These theories will help answer the main question and help with the analysis. The objects for observation are ten DVD covers from the genre romantic comedy and a qualitative content analysis is used for this thesis. The movies are from the US and they are all high in Box Office. Box Office stands for how many tickets were sold and how much money a film has earned. The use of numbers from Box Office shows that the movie had a successful marketing prior coming out as DVD. The analysis focuses also on movies from the year 2003 – 2012 as a way to get a ten years gap and also get the contemporary movies. The results show that there are codes and patterns provided from various DVD covers. Visual expressions as clothing, angles, perspectives, postures, facial expressions and colors say a lot about how the genre is visualized. It's also important for these visual expressions to work together – as they tell a story about the relationships and the characters, and also what the movie is going to be about. The main conclusion is that the woman is usually the one who is in focus and she is the active one. This doesn't necessary mean that the woman is in a higher position when it comes to the society or that she'll always have the upper hand in the relationship, but she is the one that has the upper hand right now. It's also clear that the DVD covers show when the couples aren't happily ever after.Syftet med uppsatsen är att analysera DVD-omslag för genren romantisk komedi från 2000-talet för att få fram mönster och koder som ges från genren. Det teoretiska ramverket består av tidigare forskning som analyserat olika affischer - samt teorier om semiotik, genre och visuell retorik. Dessa teorier används för att svara på frågeställningen och för att hjälpa till vid analysen. En kvalitativ innehållsanalys har analyserat tio olika DVD-omslag för genren romantisk komedi. Filmerna som analyserats är från USA och anses som höga inom Box Office. Begreppet Box Office står för hur många biljetter som har sålts och hur mycket pengar en film tjänat in. Användingen av siffor från Box Office visar att filmen hade en lyckad marknadsföring innan den kom ut på DVD, vilket gör att den används för denna analys. Analysen fokuserar sig också bara på filmer från år 2003 – 2012 då man får ett mellanrum på tio år och filmerna blir samtida. Resultatet från den kvalitativa metoden visar att det finns koder och mönster som ges från olika DVD-omslag. Visuella uttryck som kläder, vinklar, perspektiv, kroppshållning, ansiktsuttryck och färger påverkar mycket hur ett DVD-omslag uppfattas och säger mycket om hur genren visualiserats. Det är också viktigt att dessa visuella uttryck arbetar ihop då de tillsammans berättar något om relationerna, karaktärerna och vad filmen kommer att handla om. Slutsatsen visade att kvinnan oftast är den som är i fokus och aktiv. Detta betyder inte nödvändigt att kvinnan är i en högre position i samhället eller att hon kommer alltid att ha övertaget i relationen, men att hon styr just nu. Det är också tydligt att DVD-omslagen inte visar när paren är lyckliga i alla sina dagar.

Full textAbstract:
Syfte: Studiens syfte är att med hjälp av enkäter utvärdera ungdomars upplevelser under besök hos ortodontist eller ortodontiassistent i samband med behandling med fast apparatur. Målsättningen är också att belysa om det eventuellt finns några skillnader i upplevelsen beroende på vilken behandlingsteknik som används vid tandreglering. Material och metod: Studien är en del av ett större forskningsprojekt som har syftet att jämföra självligerande brackets (Damon) med konventionella brackets (Victory). Deltagarna i denna studie har efter varje behandlingstillfälle tilldelats en enkät. Frågorna handlar om hur vårdtagaren upplevt vårdgivarens kunskap, bemötande, acceptans och delgivning av information. Resultat: Totalt ingår 113 vårdtagare i studien (54 pojkar och 59 flickor). Medelåldern vid behandlingsstart var 14,7 år. Båda teknikerna fick höga betyg, vilket innebär att vårdtagarna generellt är nöjda med behandlingarna. Fem av frågorna visade signifikanta skillnader vid jämförelse mellan Damon och Victory. Frågorna som handlade om information, förståelse, acceptans samt om vårdgivaren var hårdhänt, visade skillnad vid besök 4. För frågan gällande noggrannhet visades skillnad vid besök 3, 4 och 5. Ingen signifikant skillnad mellan könen visades för någon fråga. Slutsats: Utfallet indikerar att svensk ortodontisk vård fungerar bra ur vårdtagarnas perspektiv, vilket är något som bör upprätthållas inom tandvården. Få skillnader noterades vid jämförelse mellan behandling med Damon och Victory. Resultatet kan indikera att vårdtagarens upplevelse av bemötande är mer positivt vid behandling med Damon, samt att den ortodontiska behandlingen upplevs mindre hårdhänt jämfört med Victory.Aim: The aim of this study is to examine the experiences of adolescents, during visits at the orthodontist or orthodontic assistant, for fixed appliances treatment. The purpose is also to examine possible differences in experience when treated with self-ligating or conventional brackets. Material and method: This study is a part of a larger project that aims to compare self-ligating brackets (Damon) with conventional brackets (Victory). After each treatment session the patients received a questionnaire. The questions concerning the patients experience of the care givers way of showing knowledge, acceptance, responsibility of interaction and the way of communication the information. Result: In total 113 participants were included in the study (54 boys and 59 girls). At the beginning of the treatments the average age of the participants were 14,7 years. Both techniques received high grades, meaning the patients generally were satisfied with the treatments. Five questions showed significant differences in comparison between the techniques. The questions about information, understanding, acceptance and whether the caregiver was harsh in handling, showed differences at visit 4. Regarding the question about accuracy, a difference was noted during visit 3, 4 and 5. No significant difference between the sexes was shown for any question. Conclusion: From the patient ́s point of view Swedish orthodontic care is satisfying. Few differences were noted when comparing the appliances. The results may indicate that treatment with Damon gives a more positive and less harshly experience in comparison with Victory.

Full textAbstract:
Dynamic voltage and frequency scaling (DVFS) is an extensively studied energy manage-
ment technique, which aims to reduce the energy consumption of computing platforms by
dynamically scaling the CPU frequency. Real-Time DVFS (RT-DVFS) is a branch of DVFS,
which reduces CPU energy consumption through DVFS, while at the same time ensures that
task time constraints are satisfied by constructing appropriate real-time task schedules. The
literature presents numerous RT-DVFS scheduling algorithms, which employ different tech-
niques to utilize the CPU idle time to scale the frequency. Many of these algorithms have
been experimentally studied through simulations, but have not been implemented on real
hardware platforms. Though simulation-based experimental studies can provide a first-order
understanding, implementation-based studies can reveal actual timeliness and energy con-
sumption behaviours. This is particularly important, when it is difficult to devise accurate
simulation models of hardware, which is increasingly the case with modern systems.
In this thesis, we study the timeliness and energy consumption behaviours of fourteen state-
of-the-art RT-DVFS schedulers by implementing and evaluating them on two hardware plat-
forms. The schedulers include CC-EDF, LA-EDF, REUA, DRA andd AGR1 among others,
and the hardware platforms include ASUS laptop with the Intel I5 processor and a mother-
board with the AMD Zacate processor. We implemented these schedulers in the ChronOS
real-time Linux kernel and measured their actual timeliness and energy behaviours under
a range of workloads including CPU-intensive, memory-intensive, mutual exclusion lock-
intensive, and processor-underloaded and overloaded workloads.
Our studies reveal that measuring the CPU power consumption as the cube of CPU fre-
quency can lead to incorrect conclusions. In particular, it ignores the idle state CPU power
consumption, which is orders of magnitude smaller than the active power consumption.
Consequently, power savings obtained by exclusively optimizing active power consumption
(i.e., RT-DVFS) may be offset by completing tasks sooner by running them at the highest
frequency and transitioning to the idle state earlier (i.e., no DVFS). Thus, the active power
consumption savings of the RT-DVFS techniquesâ that we report are orders of magnitude
smaller than their simulation-based savings reported in the literature.Master of Science

Une mesure précise du DVCS et du DVMP a été réalisée dans la région de valence à Jefferson Lab, avec un faisceau d'électrons de 11 GeV et une cible de protons. L'analyse des données et les résultats préliminaires de cette expérience sont présentés dans le deuxième chapitre. Une future expérience donnera encore plus de contraintes pour l'extraction des GPD. Pour cette nouvelle expérience un spectromètre à particules neutres (NPS) est en cours de construction. Dans le troisième chapitre des simulations et des développements instrumentaux pour le calorimètre de NPS sont discutés. Enfin, la caractérisation d'un nouveau verre scintillant est montrée brièvement. Ce matériau, encore en phase de développement, est un des candidats pour les calorimètres d'un futur collisionneur électron-ion (EIC)Generalized Parton Distributions (GPDs) are generalized objects describing nucleon structure. GPDs correlate the spatial and the momentum distributions of partons inside the nucleon. Therefore, they provide richer information about the nucleon structure than the well-known form factors and parton distribution functions. GPDs are accessible via exclusive reactions, where all particles in the final state are identifed. Deeply virtual Compton scattering (DVCS) and deeply virtual neutral pion production (DVMP) are discussed. The document is divided into four chapters: physics introduction, data analysis, development of a detector, and a short preview of a new scintillator material. With an 11 GeV electron beam and a proton target at Je_erson Lab, a precise DVCS and DVMP experiment in the valence quark region was performed. The data analysis and preliminary results of this experiment are presented in the second chapter. An upcoming experiment will give more constraints on the extraction of GPDs. For this new experiment, a neutral particle spectrometer (NPS) is under construction. In the third chapter, simulation studies and hardware developments for the NPS calorimeter are presented. Finally, characterizations of a new glass scintillator are shortly discussed. This material, which is in an early stage of development, is one of the candidates for the calorimeters of a future Electron-Ion Collider (EIC)

As handheld devices have become increasingly popular, powerful programmable graphics hardware for mobile and handheld devices has been deployed. While many resources on mobile devices are limited, the predominant problem for mobile devices is their limited battery power. Several techniques have been proposed to increase the energy efficiency of mobile applications and improve battery life. In this thesis, we propose a new dynamic voltage and frequency scaling (DVFS) on Graphics Processing Units (GPU). In most cases, cues within the graphics appli- cation can be used to predict portions of a GPU that will be used or unused when the application is run. We partition the GPU into six clock domains that can be clocked at different rates. Specifically, each domain it has its own voltage and frequency set- ting based on its predicted workload to save energy without reducing applications frame rates. In addition, we propose an signature-based algorithm for predicting the workload offered to our six clock domains by a given application to decide voltage and frequency settings. We conduct experiments and compare the results of our new signature based workload prediction algorithm with some other traditional interval based workload prediction algorithms. Our results show that our signature-based prediction can save 30-50% energy without afecting application frame rates.

Thesis (MSc (Clinical Psychology)) -- University of Limpopo, 2010.The Clinical Psychology training program at the University of Limpopo (Medunsa Campus) is based on the theoretical paradigm of General Systems Theory. The functioning of systems in terms of patterns, structure, organization and relationships can therefore also be applied to the trainee and his/her partner relationship system which is characterized by circular patterns of interaction. Ernst (2008) states that within the context of General Systems theory it became evident that the trainee does not function in isolation but as part of a system. The trainee undergoes significant changes throughout the training year if training is effective and this in turn may also impact on the trainee's partner relationship. This investigation was done to establish the effect of a DVD Counselling Programme on the partner-relationship of the trainee in Clinical Psychology with his/her partner/spouse. This is done in order to provide feedback to the trainers of the Clinical Psychology training at Medunsa. This may also possibly assist in establishing a more scientifically founded aid for the trainees in Msc. Clinical Psychology and their partners/spouses. It was a qualitative research project, in which person centered interviews were held with participants and thematically analyzed by three independent clinicians. The entire research project and findings are contextualized in accordance with General Systems Theory. The results indicated that the DVD had a moderate effect on 4/6 of the sample population that reported that their relationship improved in respect of the nature and quality based on mutual understanding, emotional closeness, obtaining of relational skills, effective communication and awareness regarding the impact of the training year on their relationship. The impact of the DVD was somewhat limited in that not all the participants watched it and the manner iIi which some of the trainees approached their partners/spouses, which may have had an effect on how the DVD is received and experienced.

Full textAbstract:
In this work concepts and circuits for local clock generation in low-power heterogeneous multiprocessor systems-on-chip (MPSoCs) are researched and developed. The targeted systems feature a globally asynchronous locally synchronous (GALS) clocking architecture and advanced power management functionality, as for example fine-grained ultra-fast dynamic voltage and frequency scaling (DVFS). To enable this functionality compact clock generators with low chip area, low power consumption, wide output frequency range and the capability for ultra-fast frequency changes are required. They are to be instantiated individually per core. For this purpose compact all digital phase-locked loop (ADPLL) frequency synthesizers are developed. The bang-bang ADPLL architecture is analyzed using a numerical system model and optimized for low jitter accumulation. A 65nm CMOS ADPLL is implemented, featuring a novel active current bias circuit which compensates the supply voltage and temperature sensitivity of the digitally controlled oscillator (DCO) for reduced digital tuning effort. Additionally, a 28nm ADPLL with a new ultra-fast lock-in scheme based on single-shot phase synchronization is proposed. The core clock is generated by an open-loop method using phase-switching between multi-phase DCO clocks at a fixed frequency. This allows instantaneous core frequency changes for ultra-fast DVFS without re-locking the closed loop ADPLL. The sensitivity of the open-loop clock generator with respect to phase mismatch is analyzed analytically and a compensation technique by cross-coupled inverter buffers is proposed. The clock generators show small area (0.0097mm2 (65nm), 0.00234mm2 (28nm)), low power consumption (2.7mW (65nm), 0.64mW (28nm)) and they provide core clock frequencies from 83MHz to 666MHz which can be changed instantaneously. The jitter performance is compliant to DDR2/DDR3 memory interface specifications. Additionally, high-speed clocks for novel serial on-chip data transceivers are generated. The ADPLL circuits have been verified successfully by 3 testchip implementations. They enable efficient realization of future low-power MPSoCs with advanced power management functionality in deep-submicron CMOS technologiesIn dieser Arbeit werden Konzepte und Schaltungen zur lokalen Takterzeugung in heterogenen Multiprozessorsystemen (MPSoCs) mit geringer Verlustleistung erforscht und entwickelt. Diese Systeme besitzen eine global-asynchrone lokal-synchrone Architektur sowie Funktionalität zum Power Management, wie z.B. das feingranulare, schnelle Skalieren von Spannung und Taktfrequenz (DVFS). Um diese Funktionalität zu realisieren werden kompakte Taktgeneratoren benötigt, welche eine kleine Chipfläche einnehmen, wenig Verlustleitung aufnehmen, einen weiten Bereich an Ausgangsfrequenzen erzeugen und diese sehr schnell ändern können. Sie sollen individuell pro Prozessorkern integriert werden. Dazu werden kompakte volldigitale Phasenregelkreise (ADPLLs) entwickelt, wobei eine bang-bang ADPLL Architektur numerisch modelliert und für kleine Jitterakkumulation optimiert wird. Es wird eine 65nm CMOS ADPLL implementiert, welche eine neuartige Kompensationsschlatung für den digital gesteuerten Oszillator (DCO) zur Verringerung der Sensitivität bezüglich Versorgungsspannung und Temperatur beinhaltet. Zusätzlich wird eine 28nm CMOS ADPLL mit einer neuen Technik zum schnellen Einschwingen unter Nutzung eines Phasensynchronisierers realisiert. Der Prozessortakt wird durch ein neuartiges Phasenmultiplex- und Frequenzteilerverfahren erzeugt, welches es ermöglicht die Taktfrequenz sofort zu ändern um schnelles DVFS zu realisieren. Die Sensitivität dieses Frequenzgenerators bezüglich Phasen-Mismatch wird theoretisch analysiert und durch Verwendung von kreuzgekoppelten Taktverstärkern kompensiert. Die hier entwickelten Taktgeneratoren haben eine kleine Chipfläche (0.0097mm2 (65nm), 0.00234mm2 (28nm)) und Leistungsaufnahme (2.7mW (65nm), 0.64mW (28nm)). Sie stellen Frequenzen von 83MHz bis 666MHz bereit, welche sofort geändert werden können. Die Schaltungen erfüllen die Jitterspezifikationen von DDR2/DDR3 Speicherinterfaces. Zusätzliche können schnelle Takte für neuartige serielle on-Chip Verbindungen erzeugt werden. Die ADPLL Schaltungen wurden erfolgreich in 3 Testchips erprobt. Sie ermöglichen die effiziente Realisierung von zukünftigen MPSoCs mit Power Management in modernsten CMOS Technologien

Performance and energy consumption are directly related. To increase performance, the number of instructions per second to be executed must also be increased, in other words, processor frequency must be changed. The higher this value is, higher energy consumption also has to be. Likewise, by decreasing the number of instructions to be executed, energy consumption and performance are also reduced. So, exploring performance and energy relation is the key idea behind Dynamic Voltage and Frequency Scaling – DVFS, technique. Applying DVFS in real time systems is not a trivial task. These system’s tasks are bounded to timing constraints in such a way that, if decreasing performance does not guarantee constraints, the system may totally fail. Thus, this work aims to gather two DVFS approaches in real time systems: intra and inter-tasks. The intra-task analyzes execution flow of a task and identify where the new instructions can be inserted to change supply voltage and frequency when the worst case path is not followed. On the other hand, the inter-task approach analyzes how long a task will wait due to interferences (e.g. preemption, shared resources), verifies system schedulability and defines a set of initial optimum frequencies in multi-task environment. The result is a new code with the same functionality as the original one, however with instructions to change voltage and frequency when taking into account a task interferences. Moreover, the experimental results show not only energy consumption was reduced, but also timing constraints were satisfied.
Desempenho e consumo de energia são variáveis diretamente proporcionais. Para aumentar o desempenho, é necessário também aumentar o número de instruções por segundo a serem executadas, ou seja, alterar a frequência do processador. Quanto maior for este valor, também será o consumo de energia. Do mesmo modo, reduzir o consumo de energia implica diminuir o número de instruções a serem executadas e, logo, o desempenho. Explorar a relação entre desempenho e consumo de energia é a ideia base da técnica de escalonamento dinâmico de tensão e frequência DVFS (do inglês Dynamic Voltage and Frequency Scaling). Em sistemas de tempo real críticos, aplicar a técnica DVFS não é uma tarefa trivial. Estes sistemas associam a execução de uma tarefa a um limite temporal, de modo que, se este valor não for respeitado, devido à redução do desempenho, falhas graves podem ocorrer ao sistema. Assim, esta dissertação tem como objetivo unir duas abordagens da técnica DVFS em sistemas de tempo real críticos: uma intra e outra inter-tarefas. A abordagem intra-tarefa procura analisar o fluxo de execução de uma tarefa e identificar pontos onde é possível inserir instruções para troca de frequência e tensão, quando a execução de uma tarefa se distanciar do pior caso. Já a abordagem inter-tarefas, é responsável por: analisar o tempo de espera na execução de uma tarefa devido às interferências (preempções, compartilhamento de recursos), verificar a escalonabilidade do sistema e determinar um conjunto de frequências iniciais ótimas em ambientes de múltiplas tarefas. O resultado deste estudo é a geração de um novo código com funcionalidade igual ao de entrada, porém com instruções de troca de frequência e tensão, consideradas as interferências que uma tarefa possa sofrer. Além disso, resultados experimentais mostram como não só foi possível reduzir o consumo de energia, mas também respeitar os limites temporais das tarefas em questão.

This thesis is about cover illustrations of DVD movies as examples of visual communication. I have studied the cover illustrations of the three movies Gran Torino, Secret Window and As White As Snow. My research assignment has been to find out how the cover illustrations of DVD movies communicate in relation to the story. I have also been looking for what makes a cover illustration interesting and if the interest in itself is individually considered or if there are certain general rules regardless of the observer.
To reach a conclusion I have been studying components in advertising pictures, visual communication and how the commercial producers use advertising to communicate with the observer. Semiotics, advertising and comparisons between the cover illustrations have been my method for analyze.
I have come to the conclusion that cover illustrations are meticulously produced, and that every single part of them is important for the observers’ over all impression and interpretation of the cover illustration. The place of picture elements, colours, looks and occurrence of persons in the covers are striving to send a uniform message about the cover and movie. They also guide the observer in his/her interpretation of the cover and what kind of movie it represents, and they are components that make the cover more visible. What makes the cover illustration interesting is both something individual and something general. For example the occurrence of humans, looks, strong emotions and colours make the cover more visible and interesting in relation to others. The observers’ interest for the cover may be individual depending on the observer’s experiences and interpretation.

Full textAbstract:
Extreme art cinema, has, in recent film scholarship, become an important area of study. Many of the existing practices are motivated by a Franco-centric lens, which ultimately defines transgressive art cinema as a new phenomenon. The thesis argues that a study of extreme art cinema needs to consider filmic production both within and beyond France. It also argues that it requires an historical analysis, and I contest the notion that extreme art cinema is a recent mode of Film production. The study considers extreme art cinema as inhabiting a space between ‘high’ and ‘low’ art forms, noting the slippage between the two often polarised industries. The study has a focus on the paratext, with an analysis of DVD extras including ‘making ofs’ and documentary featurettes, interviews with directors, and cover sleeves. This will be used to examine audience engagement with the artefacts, and the films’ position within the film market. Through a detailed assessment of the visual symbols used throughout the films’ narrative images, the thesis observes the manner in which they engage with the taste structures and pictorial templates of art and exploitation cinema. Through this methodological direction, the thesis is able to assess how the films are sold to an audience, how this relates to the historical progression of extreme art cinema, and the way the entire practice is informed by an ongoing tradition of taste fluidity.

Full textAbstract:
This thesis and accompanying creative product explore poetry as a multi-dimensional expression that is intrinsically inter-disciplinary. Poetry written for and practiced in media other than the page is surprisingly under-investigated. Such poetry has had difficulty establishing ‘legitimacy’ and currency in the world of practice, as traditional poetry spaces are rarely equipped, in terms of audience readiness or technological capacities, to appreciate such work. For the purposes of this investigation, the term ‘Three-Dimensional Poetic Natures’ refers specifically to poetry beyond the page, particularly in relation to performance poetry; not the imaginative landscapes created by poetic texts. Research undertaken during the course of this PhD investigated the spatial and embodied aspects of poetry beyond the page and its relationship with space, time and ecology, through creative and discursive exchanges. I use the word ‘ecological’ throughout the thesis to represent poetry and its performance as profoundly interconnected with culture, people and the environment. The word ‘ecological’ enables me to discuss poetry as a living organism in exchange with the world. ‘Ecological’ or ‘ecology’ are not used to imply eco-friendly or environmentally sustainable. The exchange that takes place in relation to animals within this dissertation and creative product also stems from the idea of ecology as a site of living and vibrant exchanges. Poetics that emerge from ecological thinking represent more than ideas, they also consider spatiality, acoustics, environments, subjectivities and texts. The poems infusing my research are technologically enabled and dependent. H2O, Liquid Stanzas and Dive, the three creative products developed during the course of this research, represent forms of ecological poetry concerned with the marine environment. As water and its inhabitants, processes and spaces are the creative focus of this investigation, I have oriented the dissertation towards an engagement with water. Performance is integral to all of the creative works; as an enactment of subjectivity and as a way of expressing voice, presence, spacetime and text (in its broadest sense). The experience of composing H2O, Liquid Stanzas and Dive helped me witness the three-dimensional nature of poetry as it mutates conventional poetic form and migrates across ecological boundaries. I chose water in order to concentrate investigations into an ecological poetics on one environment; an environment with deeply personal resonances.Thesis (PhD Doctorate)

Full textAbstract:
This creative project consists of a short fiction film which is finished on DVD and features a full length video commentary. The video commentary is an invention of my own which utilizes an often overlooked element of DVD technology, the multi-angle ability, to effectively merge two of the most popular features of modern motion picture DVD releases: the director's commentary and the production documentary. The disk actually contains two tracks of video, each of identical length. One is the film; the other is a documentary on the making of the film, with certain sections that correspond in real time with events in the film. The user has the ability to switch between tracks at anytime for comparison. This to my knowledge has never been done before, and because of the enormous popularity of the DVD and these features, may find widespread application. This project, while only an exploration of its potential, shows that the idea has feasibility and legitimacy.Department of Telecommunications

Consumers have long relied on ratings measures to help them make choices among goods of heterogeneous quality. With the growth of the New Economy over the last 10 years, it is becoming increasingly possible to aggregate information and create ratings for many industries. My research focuses on the effect of quality ratings on consumer choice, the social benefit of the quality signals, and on how well firms that develop ratings signals can capture a share of the social benefit. I examine these issues using data from Netflix, the on--line DVD rental service with mail delivery, which also provides a rating system that aggregates the preferences of the people who use their service. In the first chapter I use a reduced--form specification to analyze the Netflix ratings database and estimate aggregate demand for movies. The second chapter develops a structural Bayesian learning model and assesses the effect of ratings on DVD rental behavior. The last chapter is dedicated to the analysis of consumer and producer welfare as a function of the information created by the ratings system.

Full textAbstract:
L'image filmique est douée d'une ambivalence profonde : elle produit un effet de « réalité » et une certaine « objectivité » documentaire alors qu'elle restitue la vision du monde et le point de vue, subjectif, du cinéaste. Cette ambivalence, qui crée un rapport complexe entre la réalité étudiée et sa représentation filmique, a marqué l'histoire du cinéma ethnographique. La première partie de cette thèse analyse les procédures de la construction du regard de l'ethnographe-cinéaste, des premières chronophotographies ethnographiques émanant d'un regard supposé « objectif » au cinéma de Jean Rouch affirmant un regard subjectif à la première personne. Dans la seconde partie, l'auteur mène une réflexion sur la construction de son regard d'ethnographe-cinéaste à partir de trois de ses films (magasin Tati-Barbès et quartier de la Goutte d'Or à Paris, art décoratif des camions pakistanais). L'auteur situe sa pratique dans une démarche de recherche expérimentale en prenant en compte la subjectivité de son regard d'ethnographe et de filmeuse, inscrite dans l'image et néanmoins difficilement lisible, comme paramètre obligé de la recherche. Dans l'objectif de restituer ses expériences filmées au regard du dispositif d'observation mis en œuvre, l'auteur revisite ses propres productions filmiques par écrit et sous forme multimédia (un multimédia par film) afin d'analyser et expliciter la manière dont sa subjectivité participe de sa recherche et de son écriture cinématographique. Enfin, l'auteur explore les nouvelles perspectives d'écriture et de restitution des matériaux de terrain (images fixes et animées, sons, textes) que le multimédia offre à l'ethnographe-cinéasteThe film image has a profound ambivalence : it produces an effect of « reality » and a certain documentary « objectivity », at the same time as it stages the filmmaker's world picture and subjective point of view. This ambivalence, creating a complex relationship between the reality studied and its film representation, has marked the history of ethnographic cinema. The first part of this thesis analyses the construction procedures of the ethnographer-filmmaker's view, from the first ethnographic chronophotographs emanating from a supposedly « objective » approach, to the cinema of Jean Rouch proposing a first person subjective viewpoint. In the second part, the author reflects upon the construction of her own viewpoint as ethnographer-filmmaker through three of her films (on the Tati-Barbès department store, the Goutte d'or neighbourhood, and the decorative art of Pakistani lorries). The author describes her own practice as experimental, always taking into account the subjectivity of her own perspective as ethnographer and filmmaker (visible in the image but nevertheless not easily traceable) as an unavoidable parameter of her research. In the aim of recounting her film experiences, stressing each time the observation devices in use, the author re-examines her own film productions in written and in multimedia form (one multimedia per film), analysing and explaining the way her subjectivity participates in the cinematic research and writing. Finally, the author explores new the perspectives regarding writing and the restitution of field material (still or animated images, sounds, texts) offered today by the multimedia to the ethnographer-filmmaker

With the continuous scaling down of transistor feature sizes, the semiconductor industry faces new challenges. One of these challenges is the incessant increase of power consumption in integrated circuits. This problem has motivated the industry and academia to pay significant attention to low-power circuit design for the past two decades. Operating digital circuits at lower voltage levels was shown to increase energy efficiency and lower power consumption. Being an integral part of the digital systems, Static Random Access Memories (SRAMs), dominate the power consumption and area of modern integrated circuits. Consequently, designing low-power high density SRAMs operational at low voltage levels is an important research problem. This thesis focuses on and makes several contributions to low-power SRAM design. The trade-offs and potential overheads associated with designing SRAMs for a very large voltage range are analyzed. An 8T SRAM cell is designed and optimized for both sub-threshold and above-threshold operation. Hardware reconfigurability is proposed as a solution to power and area overheads due to peripheral assist circuitry which are necessary for low voltage operation. A 64kbit SRAM has been designed in 65nm CMOS process and the fabricated chip has been tested, demonstrating operation at power supply levels from 0.25V to 1.2V. This is the largest operating voltage range reported in 65nm semiconductor technology node. Additionally, another low voltage SRAM has been designed for the on-chip caches of a low-power H.264 video decoder. Power and performance models of the memories have been developed along with a configurable interface circuit. This custom memory implemented with the low-power architecture of the decoder provides nearly 10X power savings.

In 1997, DVD was introduced to the American public, beginning the fastest diffusion of any consumer electronics product in history. In this dissertation, I show how DVD, via favorable conditions in industry, technology, culture, economics, and the regulatory environment, replaced existing home video and computing technologies while transforming home entertainment. I analyze how DVD was successfully developed and commercialized by member firms in the filmed entertainment, consumer electronics, and computing industries from 1994-2002. I demonstrate how a new industry developed around DVD through unprecedented cooperation between these three industries. This study uses trade publications, mainstream press reports, industry data, advertisements, depositions to congress, and published interviews with industry members to analyze a process that has been understudied by scholars. Through the use of these resources, I explore how demand for the technology developed within existing contexts and how myriad forces aligned to enable the emergence of a new disc technology. Furthermore, I demonstrate how DVD reshaped these contexts while transforming the nature and business of filmed content distribution. DVD initiated a new era for digital content distribution. This era was marked by the convergence of three industries, new levels of access to filmed entertainment, mobilized viewing opportunities, the conflation of the computer and the television set, and heightened efforts to protect content through a variety of legal, regulatory, and technological strategies.

The aim of this study was to gather information on whether or not the director’s commentary feature on a DVD could develop teachers’ Film Study knowledge and skills. This mini-dissertation was directed by the following research question: can the additional information on DVDs enhance teachers’ knowledge and potential for effective teaching of Film Study? In an attempt to answer the above question a literature review was conducted to establish the importance of Professional Development and Film Study. The director’s commentary feature was then investigated as a possible development resource. By means of a qualitative Case Study that used an open-ended questionnaire and focus group interviews, data was collected from nine respondents from two different East Rand High Schools. These findings were analysed, coded and written up. The literature study also incorporates a discussion on three different types of literacy, Film Study and Film Theory. This led to the director’s commentary feature being presented as a development resource for Film Study teachers. Research indicates that Film Study is viewed as important and is valued as a part of the South African Language curriculum. This research recognises that there is a need to develop Film Study teachers in South Africa. The director’s commentary feature found on DVDs was provided as a possible solution as a Film Study development resource. Literature findings state that a director is the person responsibility for a film’s decision making process. This highlights the importance of the director and the value of the director’s commentary. However, field research could not generate a definite result some respondents found the commentary useful, whereas others did not. Whilst certain conclusions can be made regarding the director’s commentary feature, literature and field research did not correlate. Thus, the director’s commentary feature as a Film Study development resource is open for further exploration.Mrs. Catherine van der Merwe Mr. David Robinson

This thesis presents a framework which can avoid the lengthy system test by utilizing machine-learning techniques to classify parts into different DVFS bins based on the results collected at CP and FT test only. The core machine-learning techniques in use are Bayesian linear regression for model fitting and stepwise regression for feature selection. Another method, called the incremental Fmax-model search, is also presented to reduce the test time of collecting the required data for each training sample. The experiments are conducted based on 249 test chips of an industrial SoC. The experimental results demonstrate that our proposed framework can achieve a high accuracy ratio of placing a part into correct DVFS bin without placing any slower part into a faster DVFS bin. The experimental results also demonstrate that the incremental Fmax-model search can save 45.1% and 52.6% of applications of the system-level test compared to the conventional median linear search and binary search, respectively.

Taiwan is the most important production base of media storage industry in the world. In addition, the development of science and technology enables everybody to enjoy the digital services of the technology. As a result, there is a widesparead use of storage media leading to a great environmental impact that is worth our attention. This study is a real media storage industry to explore the Life Cycle Assessment (LCA) of the DVD-R and DVD-DL discs. At first, the data of raw material input, prodution, pollution emission and waste generation were first surveyed in a factory. This was then followed by investigation of the environmental impact of the DVD-R and DVD-DL discs during production and use stages. This study used the LCA software developed by ITRI, and the environmental impacts model Eco-indicator 95 to quantify the impacts. Results of the study indicate that the biggest environmental loading all comes from the consumption of the electricity both in DVD-R and DVD-DL discs during production and use stages. After the quantification by the Eco-indicator 95 based on the 1 TB storage capacity, it is found that DVD-DL discs have higher environmental impacts in the producing stage and DVD-R discs have higher environmental impacts in the use stage. During the entire life cycle that indicates the producing and use stages, this study shows that DVD-DL discs have higher environmental impacts than DVD-R discs. Based on 1 TB storage capacity, the environmental impacts of DVD-DL and DVD-R discs are 194.6, 121.3 kgCO2 for greenhouse gases, respectively; 3.31, 1.92 kgSO2 for acid depletion, respectively; 3420, 2183 MJ for energy, respectively; 15.7, 9.4 kg for solid waste, respectively; 967, 1266 kg for water resource (water consumption), respectively; 4.025E-09, 5.491E-09 kg B (a) P for carcinogens, respectively. This study shows over 90% of the environmental impacts lies in the production stage during the entire life cycle. Therefore, it’s suggested that the disc manufaturer improve the production processes for making higher capacity and higher read/write speed discs for a better environment.
