Full textThe 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 textEl 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.

Full textDen här uppsatsen handlar om en DVD-instruktion kan vara ett nytt hjälpmedel för att underlätta elevens självvärdering och ersätta eller komplettera trafiklärarens kördemonstration
vid övningskörning.
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 textSyftet 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 textAim: 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 textGeneralized 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)

In the paper the available tools and methods of data security are analyzed, security methods for CD and DVD media are discussed. The information collected on the data copy-protect and cryptography as well as use security is used in an experiment aiming to identify the most fitting methods for software of data security. The implementation of the experiment is aimed at checking the time input for cryptography algorithms. For this purpose the crypt and decrypt operations with 10 MB and100 MB files are performed. The developed system allows to keep data safe from illegal review and use in CD and DVD. Safety data records developed with the help of the system may be used without any extra software in other computers in which Windows XP/Vista/Win7 operation system is installed.

Full textThe High-Performance Computing (HPC) community is currently undergoingdisruptive technology changes in almost all fields, including a switch towardsmassive parallelism with several thousand compute cores on a single GPU oraccelerator and new, complex networks. Powering a massively parallel machinebecomesThe energy consumption of these machines will continue to grow in the future,making energy one of the principal cost factors of machine ownership. This explainswhy even the classic metric "flop/s", generally used to evaluate HPC applicationsand machines, is widely regarded as to be replaced by an energy-centric metric"flop/watt".One approach to predict energy consumption is through simulation, however, a pre-cise performance prediction is crucial to estimate the energy faithfully. In this thesis,we contribute to the performance and energy prediction of HPC architectures. Wepropose an energy model which we have implemented in the open source SimGridsimulator. We validate this model by carefully and systematically comparing itwith real experiments. We leverage this contribution to both evaluate existingand propose new DVFS governors that are part*icularly designed to suit the HPCcontext

Full textThe 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 textIn 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.

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 textThe 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.

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.
