Texto completoResumen
Benchmarking of DSP kernel algorithms was conducted in the thesis on a DSP processor for teaching in the course TESA26 in the department of Electrical Engineering. It includes benchmarking on cycle count and memory usage. The goal of the thesis is to evaluate the quality of a single MAC DSP instruction set and provide suggestions for further improvement in instruction set architecture accordingly. The scope of the thesis is limited to benchmark the processor only based on assembly coding. The quality check of compiler is not included. The method of the benchmarking was proposed by BDTI, Berkeley Design Technology Incorporations, which is the general methodology used in world wide DSP industry.
Proposals on assembly instruction set improvements include the enhancement of FFT and DCT. The cycle cost of the new FFT benchmark based on the proposal was XX% lower, showing that the proposal was right and qualified. Results also show that the proposal promotes the cycle cost score for matrix computing, especially matrix multiplication. The benchmark results were compared with general scores of single MAC DSP processors offered by BDTI.

Since a few years, flat screen TVs, such as LCD and plasma, has come to completelydominate the market of televisions. In a SoC solution for digital TVs, severalprocessors are used to obtain a decent image quality. Some of the processorsneed temporal information, which means that whole frames need to be storedin memory, which in turn motivates the use of SDRAM memory. When higherdemands of resolution and image quality arrives, greater pressure is put on theperformance of the SoC memory subsystem, to not become a bottleneck of thesystem.
In this master thesis project, a model of an existing SoC for digital TVs is usedto benchmark and evaluate the performance of an SDRAM memory controllerarchitecture study. The two major features are the ability to reorder transactionsand the compatibility with DDR3. By introducing reordering of transactions, thechoice is given to the memory controller to service memory requests in an orderthat decreases bank conflicts and read/write turn arounds. Measurements showthat a utilization of 86.5 % of the total available bandwidth can be achieved, whichis 18.5 percentage points more, compared to an existing nonreordering memorycontroller developed by NXP.

This Bachelor thesis paper investigates 2 different methods used to solve the Rubik’s Cube 4x4x4 puzzle. The analyzed methods are Reduction and Big Cube method. We have implemented the cube and the two solvers in Python. Through a series of tests we have concluded that the Big Cube method has a better average move count as well as a low standard deviation in comparison to the Reduction method. However the reduction method has a lower minimum move count and consists of fewer algorithms. The best approach would be to combine both methods to form an optimal solution.Denna kandidatexamensuppsats undersöker två olika metoder som används för att lösa Rubiks Kub 4x4x4. Metoderna som analyseras är Reduction och Big Cube. Vi har implementerat kuben samt de bägge lösarna I Python. Genom en serie tester har vi kommit fram till att Big Cube har ett lägre genomsnittligt rotationsantal samt lägre standardavvikelse än Reduction. Reductionmetoden har däremot ett lägre minimumvärde på antalet rotationer och består av färre algoritmer. Det bästa tillvägagångssättet vore att kombinera de båda lösningarna.

Texto completoResumen
The aim of this paper is to describe benefits of benchmarking IT in wider context and benchmarking scope at all. I specify benchmarking as a process and mention basic rules and guidelines. Further I define IT benchmarking domains and describe possibilities of their use. Best known type of IT benchmark is cost benchmark which represents only a subset of benchmark opportunities. In this paper, is cost benchmark rather an imaginary first step to benchmarking contribution to company. IT benchmark is not only a method for comparing IT efficiency, but also a way to better co-ordinate IT work with company strategy or make IT work more transparent for their customers. IT benchmark facilitates continual improvement not only to internal IT processes, but also to services that IT provides and in consequence to supported business services. Reader will further familiarize with practical example of IT process benchmark and with specifics in benchmarking of outsourced processes. It should be possible based on this paper to set strategic aims in benchmarking. And second, to run an initial IT process benchmark project.

As indústrias de manufatura, para permanecerem competitivas, produzem uma grande quantidade de produtos diferentes para atender a demanda do mercado, e para isto são necessários inúmeros recursos dentre os quais se incluem as ferramentas de usinagem. O presente trabalho está relacionado aos problemas enfrentados por essas indústrias nas várias atividades que envolvem o uso de ferramentas de usinagem, incluindo aquisição, armazenagem, desenvolvimento de banco de dados, seleção, alocação, inspeção, preparação, controle de inventário, reciclagem, descarte entre outras. O gerenciamento de ferramentas de usinagem é uma estratégia que visa contribuir com todas essas atividades, e um momento importante é a fase inicial do projeto de implantação, onde o reconhecimento da situação atual, através de um diagnóstico, é o ponto de partida para o planejamento de sua implantação e realização de melhorias contínuas. Os gerentes de produção destacam a falta de procedimentos contendo métricas e metas estabelecidas que lhes informem se a empresa está ou não conseguindo fazer um gerenciamento eficiente e capaz de suportar o processo de implantação. Neste contexto, esse trabalho apresenta um método para realização de um diagnóstico de práticas e performances do gerenciamento de ferramentas de usinagem de empresas que trabalham com ferramentas de usinagem em seus meios produtivos, abordando os aspectos estratégicos, técnicos e logísticos, e em especial no que se refere ao gerenciamento focado na Manufatura Enxuta e aspectos ambientais relacionados a esta estratégia. Foram realizadas pesquisas de campo em nove empresas do setor metal mecânico para a aplicação do método proposto, o qual foi inspirado pelo método Benchmarking Enxuto, que já foi aplicado em alguns estudos de caso encontrados na literatura. Das nove empresas pesquisadas, duas são de médio porte e sete de grande porte, onde oito tiveram altos índices de práticas e performance (acima de 60%), e apenas uma empresa teve baixos índices de práticas (abaixo de 60%) e altos índices de performance. Com a aplicação do método desenvolvido pode-se observar que em relação aos aspectos ambientais relacionados ao gerenciamento de ferramentas de usinagem, a maior parte das empresas pesquisadas teve resultados muito bons, evidenciando que as mesmas possuem uma grande preocupação com a preservação do meio ambiente e também melhor aproveitamento dos recursos gastos na usinagem de peças.

A busca incessante por menores custos de produção faz com que as empresas invistam em sistemas de produção mais eficientes para que possam manter-se economicamente competitivas, enquanto que as ações focando em operações mais sustentáveis do ponto de vista ambiental são executadas apenas visando atender as políticas governamentais que regulamentam o controle ambiental. No entanto, ainda é comum que as empresas concentrem seus esforços em minimizar os impactos ambientais apenas na fase inicial do ciclo de vida do produto, negligenciando a gestão da sustentabilidade na fase de pós-uso. Tendo em vista esse contexto, o objetivo do presente trabalho consiste em desenvolver indicadores de sustentabilidade, que possam ser utilizados pela indústria de produtos eletrônicos para mensurar o nível de prática e performance. Durante o processo produtivo que estão relacionados à recuperação do produto após a fase de uso, com a finalidade de melhor compreender como as empresas estão agindo durante o processo de produção visando reduzir os impactos ambientais de seus produtos no final do ciclo de vida. Para o desenvolvimento do método foi criado um conjunto de indicadores que servem de subsídio para o gerenciamento ambiental no final do ciclo de vida do produto. Os indicadores foram obtidos por meio dos fatores críticos de sucesso encontrados através do levantamento bibliográfico em publicações científicas e validados em um estudo exploratório, buscando estabelecer indicadores especificamente para a gestão do final do ciclo de vida de produtos eletrônicos. Para conferir a validade dos indicadores desenvolvidos foi realizado benchmarking em nove empresas do setor de eletrônicos, a análise dos dados ocorreu de forma quantitativa e qualitativa, abrangendo quadros comparativos, tabelas e gráficos obtidos mediante o questionário e entrevistas. Com os resultados apresentados no benchmarking, conclui-se que os indicadores desenvolvidos na pesquisa são adequados para o objetivo de mensurar os níveis de práticas e performance da indústria de eletrônicos no gerenciamento ambiental no final do ciclo de vida dos produtos pois os mesmos foram capazes de retratar de forma fidedigna a realidade de cada empresa.
Abstract : The relentless pursuit of low production costs cause companies to invest in more efficient production systems so that they can remain economically competitive. They focus on operations from environmental point of view, only to meet the regulations imposed by the regulating bodies. However, it is common for companies to focus their efforts to minimize the environmental impact only during at early stage of product development, neglecting sustainable management in the post-use phase. Given this context, the objective of the study is to develop sustainability indicators that can be used by the electronics industry to measure the level of practice and performance during the product recovery phase - after the phase of use, in order to better understand how companies are acting in the production processes to reduce the environmental impact of their products at the end of life cycle. The developed method includes a set of indicators that serve as allowance for environmental management at the end of the product life cycle. The indicators were obtained through the critical success factors found through literature surveys in scientific journals. They are validated in exploratory study, to establish indicator specificity for the end of the management of electronic product life cycle. The benchmark validity of indicators developed was observed in 9 electronic companies. The quantitative and qualitative analysis of the data was obtained through the questionnaire and interviews and presented in comparative tables, charts and graphs. The study concludes with the results presented in benchmarking and the indicators developed in the research. The developed indicators are suitable to measure the levels of practices electronic industry perform in environmental impact management at the end of product life cycle as they represent accurately the reality of each company.

Texto completoResumen
Människan har i alla tider jämfört sig själv med andra, och det kan ses som en naturlig sak att jämförelser även sker på de arbetsplatser vi jobbar på. Xerox såg under 70-talet möjligheter att jämföra sig mot sina konkurrenter för att finna de bästa tillvägagångsätten, vilket gick under benämningen Benchmarking. Verktyget har även på senare tid fått inflytande inom den kommunala sektorn då högre krav ställs på att vara effektivare, samt införande av nya lagar som exempelvis Lagen om Valfrihetssystem (LOV) vilket öppnar upp för konkurrens från privata verksamheter. Det intressanta med benchmarking är att, trots den ökade populariteten och den stora mängd forskning som har gjorts kring fenomenet, finns det idag en fragmenterad bild över benchmarkingens delar. Syftet med studien har varit att analysera hur benchmarkingarbete kan gå till i en kommunal förvaltning. I vår teoretiska referensram valde vi att dela in benchmarking i delarna Vad, Var och Hur då dessa delar utförligt beskriver benchmarkingens aspekter. För att få en djupare förståelse för området och särskilja oss från tidigare studier valde vi att genomföra en kvalitativ studie på två förvaltningar där vi intervjuade förvaltningschefen samt den ekonomiansvariga. Resultatet av studien visar att valet av perspektiv i stor utsträckning påverkar uppfattningen av hur benchmarking används i förvaltningar, och att det därför kan vara svårt att se tidigare forskning, utförd ur endast ett perspektiv som en representation för en hel förvaltnings användning av benchmarking.

Texto completoResumen
This Master thesis describes the benchmarking of a DSP processor. Benchmarking means measuring the performance in some way. In this report, we have focused on the number of instruction cycles needed to execute certain algorithms. The algorithms we have used in the benchmark are all very common in signal processing today.
The results we have reached in this thesis have been compared to benchmarks for other processors, performed by Berkeley Design Technology, Inc.
The algorithms were programmed in assembly code and then executed on the instruction set simulator. After that, we proposed changes to the instruction set, with the aim to reduce the execution time for the algorithms.
The results from the benchmark show that our processor is at the same level as the ones tested by BDTI. Probably would a more experienced programmer be able to reduce the cycle count even more, especially for some of the more complex benchmarks.

Benchmarking is a well established and respected mechanism that contributes to organisational improvement. Its epistemology demonstrates it to be theoretically underdetermined with literature focusing on pragmatism and praxis. Benchmarking's critics hold it to be a-theoretical; failing to provide its practitioners with a reliable basis for distinguishing between effective and ineffective efforts. The purpose of this thesis is to review Benchmarking's epistemology and identify the necessary or sufficient methodological elements contributing to its effectiveness and to establish them within an acceptable theoretical framework. A causal approach is applied to the objectives of organisational benchmarking's current definitions and implementation frameworks. The resulting theoretical framework is then validated against current exemplary benchmarking praxis to explain its effectiveness and satisfy historical criticisms. Central to the approach is the application of supervenience and entailment relationships between benchmarking parties within the umbrella of Peircean Causation to determine the feasibility of a benchmarking proposition. Benchmarking's a priori effectiveness (sufficiency) can be established from an organisational axiom and five logical conditions. This research establishes a new encompassing definition of benchmarking reduces its typology to a single consistent form and establishes an Effective Benchmarking Process that explains current practices and addresses historical criticisms. These logical conditions also explain the effectiveness of empirical frameworks such as the Malcolm Baldrige National Quality Award and ISO 9000. A theoretical foundation for benchmarking provides a platform for extending the theory of organisational improvement. It also has significant potential to enhance organisational sustainability by reducing wasted effort. This research focuses on the causal linkages between benchmarking and organisational sustainability. The research establishes a new definition of benchmarking, specifies necessary and sufficient conditions for its application and frames practitioner efforts within an Effective Benchmarking Process (EBP).

Texto completoResumen
Points-to analysis is a static program analysis that, simply put, computes which objects created at certain points of a given program might show up at which other points of the same program. In particular, it computes possible targets of a call and possible objects referenced by a field. Such information is essential input to many client applications in optimizing compilers and software engineering tools. Comparing experimental results with respect to accuracy and performance is required in order to distinguish the promising from the less promising approaches to points-to analysis. Unfortunately, comparing the accuracy of two different points-to analysis implementations is difficult, as there are many pitfalls in the details. In particular, there are no standardized means to perform such a comparison, i.e, no benchmark suite - a set of programs with well-defined rules of how to compare different points-to analysis results - exists. Therefore, different researchers use their own means to evaluate their approaches to points-to analysis. To complicate matters, even the same researchers do not stick to the same evaluation methods, which often makes it impossible to take two research publications and reliably tell which one describes the more accurate points-to analysis. In this thesis, we define a methodology on how to benchmark points-to analysis. We create a benchmark suite, compare three different points-to analysis implementations with each other based on this methodology, and explain differences in analysis accuracy. We also argue for the need of a Gold Standard, i.e., a set of benchmark programs with exact analysis results. Such a Gold Standard is often required to compare points-to analysis results, and it also allows to assess the exact accuracy of points-to analysis results. Since such a Gold Standard cannot be computed automatically, it needs to be created semi-automatically by the research community. We propose a process for creating a Gold Standard based on under-approximating it through optimistic (dynamic) analysis and over-approximating it through conservative (static) analysis. With the help of improved static and dynamic points-to analysis and expert knowledge about benchmark programs, we present a first attempt towards a Gold Standard. We also provide a Web-based benchmarking platform, through which researchers can compare their own experimental results with those of other researchers, and can contribute towards the creation of a Gold Standard.

With the rise of cloud computing, many cloud storage systems like Dropbox, Google Drive and Mega have been built to provide decentralized and reliable file storage. It is thus of prime importance to know their features, performance, and the best way to make use of them. In this context, we introduce BenchCloud, a tool designed as part of this thesis to conveniently and efficiently benchmark any cloud storage system.First, we provide a study of six commonly-used cloud storage systems to identify different types of their features. Then existing benchmarking tools for cloud systems are presented, and the requirements, design goals and internal architecture of BenchCloud are studied. Finally, we show how to use BenchCloud to analysis cloud storage systems and take a series of experiments on Dropbox to show how BenchCloud can be used to benchmark and inspect various kinds of features of cloud storage systems.

Bei der modernen Videoencodierung werden viele Berechnungen benötigt. Unter anderem wird das Bild in Makroblöcke zerlegt, Bewegungsvektoren berechnet und Bewegungsvorhersagen getroffen, um Speicherplatz für die komprimierte Datei zu sparen. Der x264-Encoder versucht das auf verschiedene Arten und Weisen zu realisieren, wodurch der eigentliche Encodier-Vorgang langsam wird und auf älteren oder langsameren PCs deutlich länger dauert als andere Verfahren. Außerdem verwendet der x264-Encoder Standards wie SSE, AVX oder OpenCL um Zeit zu sparen, indem mehrere Daten gleichzeitig berechnet werden. Daher eignet sich x264 auch zur Evaluation solcher Standards und der Untersuchung des Geschwindigkeitsgewinns durch die Verwendung von Vektoroperationen oder Grafikbeschleunigung.

Support Vector Machines (SVMs) are rarely benchmarked against other classification or regression methods. We compare a popular SVM implementation (libsvm) to 16 classification methods and 9 regression methods-all accessible through the software R-by the means of standard performance measures (classification error and mean squared error) which are also analyzed by the means of bias-variance decompositions. SVMs showed mostly good performances both on classification and regression tasks, but other methods proved to be very competitive.Series: Report Series SFB "Adaptive Information Systems and Modelling in Economics and Management Science"

Texto completoResumen
L’objectif principal de cette thèse est d’obtenir une comparaison réaliste et équitable des performances des protocoles et des applications pour les réseaux sans fil. Dans la communauté réseau, la simulation est l’approche prédominante pour l’évaluation comparative des protocoles, cependant, elle manque de réalisme car elle utilise le plus souvent des modèles simplifiés des couches de communication. D’un autre côté, les expérimentations sans fil effectuées dans le monde réel sont réalistes mais elles compliquent fortement la comparaison équitable des protocoles. En effet, la comparaison équitable des protocoles dépend de l’interprétation correcte des résultats et de la « répétabilité » de l’expérimentation. L’interprétation correcte des résultats est un problème majeur pour les expérimentations sans fil car il n’est pas facile de tenir compte de l’ensemble des paramètres qui peuvent avoir un impact sur les performances des protocoles en particulier, les conditions du canal, les paramètres de configuration des outils de mesure. Avec les expérimentations sans fil, la « répétabilité » des résultats est quasiment impossible à obtenir en raison du caractère aléatoire du canal de transmission. Quant à la « comparaison équitable » des protocoles, elle est complexe à obtenir et nécessite une méthodologie standard. Dans cette thèse, nous proposons une méthodologie d’expérimentation dont l’objectif est d’assurer une interprétation correcte des résultats expérimentaux. Cette méthodologie est composée des étapes suivantes : caractérisation de canal pour déterminer les conditions exactes de canal, calibrage des outils de mesure, spécification de la configuration du scénario à l’aide d’outils simples. Dans les expérimentations sans fil, les ondes radio sont affectées par des phénomènes multiples et complexes comme l’atténuation en fonction de la distance, les réflexions sur le sol ou les murs qui peuvent provoquer l’évanouissement du signal. De plus, le déplacement d’objet ou de personnes entre émetteurs et récepteurs et à la proximité d’autres réseaux sans fil peuvent introduire des interférences que l’on ne peut pas ignorer. D’autres part, les expérimentateur peuvent facilement faire des erreurs si les outils et les logiciels utilisés sont mal configurés. Pour cela, il est important de spécifier de manière précise et détaillée le scénario d’expérimentation. Cette spécification doit inclure la séquence des étapes et la description des tâches à effectuer à chaque étape de l’expérimentation. Les tâches comprennent la génération de trafic, la capture des paquets (e. G. à l’aide de sondes), la capture de traces RF (e. G. Avec un analyseur de spectre) et la collecte d’autres mesures, comme la charge CPU des machines utilisées. Pour interpréter correctement les résultats, comme ces informations peuvent être très volumineuses, elles doivent être organisées et présentées de manière efficace. Dans cet objectif, nous proposons l’établissement d’un rapport détaillé appelé FDR (« Full Disclosure Report »). Comme la « répétabilité » des expérimentations sans fil est impossible à obtenir dans un environnement non contrôlé, notre objectif est de pouvoir répéter des résultats statistiques. Ces derniers sont obtenus en regroupant les résultats d’expérimentations multiples qui ont eu lieu avec des conditions d’environnement similaire. Etant donné que les expérimentations sans fil sont fastidieuses à réaliser et sujettes aux erreurs humaines, nous avons développé une boîte à outils permettant de faciliter le benchmark. Ces outils permettent de décrire les scénarios, gérer la planification d’un grand nombre d’expérimentations et traiter l’énorme quantité de traces qui en résultent, sauvegarder les métadonnées et leur provenance (enregistrement chronologique des étapes de mesure et d’analyse), ainsi que les résultats d’expérimentation. Enfin, nous illustrons et validons notre méthodologie de benchmark avec deux cas d’étudeThe objective of this thesis is to enable realistic yet fair comparison of the performance of protocols and applications in wireless networks. Simulation is the predominant approach for comparable evaluation of networking protocols however it lacks realism and can lead to misleading results. Real-world experiments guarantee realism but complicate fair comparison. Fair comparison depends on correct interpretation of the results and repeatability of the experiment. Correct interpretation of results is an issue in wireless experiments because it is not easy to record all the factors (e. G. Channel condition s, calibration settings tools and test scenario configurations) that can influence the network performance. Repeatability of experiments is almost impossible because of channel randomness. In wireless experiments, “realism” can be taken of granted but “fair comparison” requires a lot of hard work and is impossible without a standard methodology. Therefore, we design a workable experimentation methodology which tackles the aforementioned issues as follows. To ensure correct interpretation of the results, we need to accomplish the following : channel characterization to determine the exact channel conditions, calibration of tools to avoid pitfalls, a simple mechanism to specify scenario configurations. Channel conditions such as path loss, fading an interference are a direct result of radio propagation, movement of objects and co-existing Wi-Fi networks/devices in the environment respectively. Pitfalls mainly result from imperfections / bugs or wrong configurations of a tool. Scenario description consists of a precise specification of the sequence of steps and tasks to be performed at each step. Tasks include traffic generation, packet trace capture (using a sniffer). RF traces capture (using spectrum analyzer) and System/network workload collection. Correct interpretation of results requires that all this information be organized and presented in an easily digestible way to the reviewer. We propose Full disclosure report (FDR) for this purpose. Repeatable experimentation requires additional work. As repeatability is impractical in the wild wireless environment, we propose statistical repeatability of results where experiments are clustered based on the similarity of networking conditions (channel conditions, station workload, network traffic load) and scenario configurations. The, it is possible to make a comparison based on the similarity of conditions. Providing tools to allow a user-friendly mechanism to apply the methodology is also equally important. We need tools to easily describe scenarios, manage scheduling and large number of runs (possibly hundreds or thousands) of them. We also need tools to manage huge amount of packet trace data, metadata and provenance (chronological record of measurement and analysis steps) of results (figures, tables, graphs etc. ). Therefore, in addition to the methodology, we developed a toolbox for a wireless experimentation and carried out of two case studies to validate the methodology. In short, we present a holistic view of benchmarking in wireless networks, formulate a methodology complemented by tools and case studies to help drive future efforts on benchmarking of protocols and applications in wireless networks

Texto completoResumen
Denna rapport ämnar undersöka de vanligast förekommande typerna av teknologier för vågkraftverk (eng. Wave Energy Converter, WEC) teknologier för att jämföra de olika konceptens förmåga att absorbera vågenergi. Koncept som undersöks är punktabsorbatorer och oscillerande vattenkolumner. I denna rapport används de vanligt använda engelska översättningarna point absorber och oscillating water column (OWC). Beräkningar görs för de olika koncepten i liknande vågförhållanden för att kunna jämföra den energi som kan utvinnas. I rapporten sker beräkningar under optimala vågförhållanden. Vågorna antas vara linjära och vågkraftverken antas vara i fas med vågens svängningsrörelse. Den vågdata som använts är uppmätt utanför Belmullet i Irland. Beräkningar görs på vågor med en signifikant våghöjd på 1,25 m och en periodtid på 7,5 s. Det görs även beräkningar på den största uppmätta förekommande vågen. I huvudsak används effektberäkningar enligt en modell som Kjell Budal. Syftet är att grafiskt och numeriskt jämföra den teoretiska och faktiska maxeffekt som kan utvinnas ur respektive våg. Resultatet från undersökningen visar att den största bidragande faktorn till en hög energiutvinning beror på bojens volym. Volymen måste anpassas för de vågförhållanden som finns där bojen ska placeras.Vid beräkningar av en OWC med tvärsnittsarea på 19 m2 visar det sig att den effekt som kan utvinnas av en luftkammare med tillhörande turbin är ungefär 10 kW, 1/30 av de 300kW som kan utvinnas av en point absorber. En OWC består dock sällan utav en ensam luftkammare utan ofta i en array med ett flertal luftkammare med separata turbiner för att öka effekten.This report intends to examine the most common types of wave energy converter technologies to compare the different concepts' ability to absorb wave energy. Concepts being investigated are point absorbers and oscillating water columns (OWC). Calculations are made for the different concepts in the same wave conditions to be able to compare the energy that can be extracted. In the report, calculations are made under optimal wave conditions. The waves are assumed to be linear and the wave energy converter is assumed to be in phase with the oscillating motion of the wave. The wave data used is measured outside Belmullet in Ireland. Calculations are made on waves with a significant wave height of 1.25 m and a period time of 7.5 s. Calculations are also made on the largest measured wave present. In essence, power calculations are used according to a model developed by Kjell Budal and with the help of this be able to graphically and numerically compare the theoretical and actual maximum power that can be extracted from each scale. The results from the survey show that the largest contributing factor to high energy recovery is due to the volume of the buoy. The volume must be adapted to the wave conditions that exist where the buoy is to be placed.When calculating an OWC with a cross sectional area of 19 m2, it turns out that the power that can be extracted from an air chamber with an associated turbine is approximately 10 kW, 1/30 of the 300 kW that can be extracted by one point absorber.

Texto completoResumen
Titel: Benchmarking - Den nya budgeten Bakgrund: Budget är ett mycket utbrett styrverktyg som under senare år kommit att kritiseras. Kritiken menar på att en budget är för stelbent i en värld som snabbt förändras och att styrverktyg krävs som passar in i dagen förutsättningar. Flera företag har med detta valt att tillämpa en budgetlös styrmodell då de anser att budgeten inte kan möta den osäkerhet som marknaden idag besitter. Ett populärt verktyg som bättre kan möta de krav som företag ställs inför idag är benchmarking. Genom att jämföra och lära inom organisationen såväl som att utbyta kunskaper externt med andra företag strävar företagen efter att nå ”best practice”. Syfte: Syftet med denna studie är att ta fram ett teoretiskt ramverk för hur benchmarking kan ersätta budgetens syften. I nästa steg beskrivs och jämförs hur tvåbudgetlösa företag arbetar med intern benchmarking på huvudkontorsnivå och kontor/butiksnivå. Studien bidrar med material till hur benchmarking används som substitut till budget i företag och syftar till att belysa hur olika nivåer uppfattar begreppet inom företaget. Teoretisk referensram: Den teoretiska referensramen i vår studie utgör en presentation av budgetering, budgetlös styrning samt olika styrsätt för att ersätta budgetens syften. Ett stort fokus har lagts på benchmarking där delar som syfte, processen, benchlearning, intern och extern benchmarking samt för- och nackdelar belyses för att få en tydlig bild över begreppet som en del i ett styrsystem. Benchmarking tillsammans med olika styrsätt beskrivs för att jämföra dessa med budgetens syften. Metod: Vi har utfört en jämförelsestudie på två budgetlösa företag. Företagen är Handelsbanken AB och Ahlsell AB. I vår studie har ett kvalitativt angreppssätt tillämpats för att samla in och analysera det empiriska materialet. Resultat: Studien visade att enligt teorin kan benchmarking ersätta alla budgetenssyften utom två. Dessa två syften, planering och resursallokering, kan ersättas genom att använda komplementet rullande prognoser. Benchmarking kan av denna anledning inte ersätta budget helt utan är i behov av komplement för att utgöra ett komplett substitut. Detta är också något som bekräftas av det empiriska materialet som samlats in om företagen Ahlsell och Handelsbanken. I jämförelse mellan olika nivåer på de två fallföretagen konstateras i studien att i kontrast till forskning som menar på att benchmarking ofta görs för generellt eller på en för central nivå i företagen, har det av denna studie visats att så inte är fallet. Benchmarking används på olika nivåer av fallföretagen och liknar till stor del ledningens syn på styrverktyget.Titel: Benchmarking - The new budget Background: Budget is a widely used management tool which has been criticized during recent years. The critique implies that a budget is too rigid in a world with swift changes and that management tools are needed which meet the playing conditions of today. Several companies have chosen to implement a model that goes beyond budgeting. This is a consequence of the fact that they believe a budget cannot face the uncertainty that the market possesses. A popular tool which is able to meet the struggles that companies face is benchmarking. By comparing and learning within the organization as well as exchanging knowledge with other companies, these actors are trying to reach best practice. Purpose: The purpose with our study is to create a theoretical framework of how benchmarking can substitute the purpose of budgeting. The next step is to use the framework to compare internal benchmarking within different levels in two companies. Our study has the aim to contribute with knowledge of how benchmarking can substitute budgeting. This study also aims to address how different levels, top and ground level, interpret benchmarking within the company. Theoretical framework: This study’s theoretical framework consists of budgeting, beyond budgeting and management tools with the aim of finding a substitute for budget.The focus is on benchmarking and consists of the purpose, the process, benchlearning, internal and external benchmarking as well as advantages and disadvantages to create a broad understanding of the concept. Method: We conduct a comparison study of two companies practicing beyond budgeting. The companies are, Handelsbanken AB and Ahlsell AB. In our study, we have applied a qualitative approach to collect and analyse the empirical material. Findings: The study shows that according to theory, benchmarking is able to substitute all the purposes of budget except for two. These two purposes, planning and resource allocation, could be substituted by the complement rolling forecasts. Benchmarking could, for this reason, not on its own substitute the budget, but needs to be complemented in order to form a complete substitute for budget. This theory is confirmed by the empirical material gathered from two companies, Ahlsell and Handelsbanken. In comparison between the different levels within the companies, a conclusion is made that in contrast to earlier suggestions, benchmarking is not implemented too generally or only on a centralized basis. It is used on different levels within the companies and the view of benchmarking is more or less uniform between these levels.

OpenVG is a new open standard for 2 dimensions vector graphics for handheld devices. This project, which is a master thesis and an internship, aims to study the standard itself deeply before to study the role it can play in the future of artistic content creation.We will see that under some few conditions, OpenVG has everything to fulfil its role in the market and to attract digital artists who would like to enlarge their creation field. But the major aim of the project is to develop a benchmark for both hardware and software implementations. And to achieve this goal, a study of the theory of performance evaluation is necessary. And after developing the benchmark, it is interesting to run some few tests to illustrate some principles enounced while studying performance evaluation.

Meier, A. M. "Randomized Benchmarking of Clifford Operators". Thesis, University of Colorado at Boulder, 2013. http://pqdtopen.proquest.com/#viewpdf?dispub=3592339.
Texto completoResumen
Randomized benchmarking is an experimental procedure intended to demonstrate control of quantum systems. The procedure extracts the average error introduced by a set of control operations. When the target set of operations is intended to be the set of Clifford operators, the randomized benchmarking algorithm is particularly easy to perform and its results have an important interpretation with respect to quantum computation. The aim of the benchmark is to provide a simple, useful parameter describing the quality of quantum control with an experiment that can be performed in a standard way on any prospective quantum computer. This parameter can be used to fairly compare different experiments or to mark improvement in a single experiment.
In this thesis I discuss first the original randomized-benchmarking procedure and the importance of the Clifford operators for its implementation. I develop the statistical analysis of the results and the physical assumptions that are required for the simplest analysis to apply. The original procedure does not extend in an obvious way to benchmarking of more than one qubit, so I introduce a standardized procedure for randomized benchmarking that applies to any number of qubits. This new procedure also enables the benchmarking of an individual control operation. I describe two randomized-benchmarking experiments I helped to design: one involved a single qubit and utilized a variation of the original procedure and the second involved two qubits and demonstrated the new procedure. I conclude with several potential extensions to the original and new procedures that give them reduced experimental overhead, the ability to describe encoded operations, and fairer comparisons between experiments.

Bohlke, Nikolai. "Benchmarking of elite sport systems". Thesis, Loughborough University, 2006. https://dspace.lboro.ac.uk/2134/12193.
Texto completoResumen
The organisation of elite sport systems has been the focus of a great variety of different investigations over the past ten years. In particular, many studies have compared the structure and organisation of different national elite sport systems on the macro and meso levels. A result of the existing investigations is a clear convergence of the service portfolio different elite sport systems offer their athletes and coaches. Despite this current trend to a homogeneous elite sport system design, medal tables of major sport events suggest that some nations are still more successful than others in specific sports. This suggests that more successful sport systems might have found better ways to implement the otherwise similar and conventional support portfolio. However, there is a lack of studies that focus on what practices successful elite sport systems apply in the actual delivery of the support services to their athletes and coaches; in how far these practices are related to the ,success of the sport systems; if these practices look similar across different successful sport systems; and if these practices provide useful lessons for other systems to learn from. The management tool benchmarking appears to be a useful framework to guide such comparisons at the operational level. Thus, this thesis evaluated the applicability of this management concept for furthering understanding of elite sport system management. In order to conduct this evaluation it was decided to analyse the operational processes and structures two successful elite sport systems apply for the delivery of five elements of the elite sport support portfolio. In specific, the investigation focused on the comparison of the design of the squad system, the hierarchy of coaches within the squad system, the organisation of the coach education, as well as the provision of sport science and lifestyle support, which were the Benchmarking Objects of this study. The Swedish athletics and the Norwegian cross-country skiing national team, and the general elite sport support institutions they cooperate with, were chosen as the Benchmarking Subjects, i.e. the comparison partners, for this investigation. This research was based on a series of semi-structured interviews which were conducted with about 50 key pOSition holders such as coaches, athletes, lifestyle support managers, or performance diagnosticians during two study visits to Norway and Sweden. This study concluded that benchmarking can lead to insights into the operational management of successful elite sport systems. It must however also be stressed that benchmarking is not a universal remedy for the problems managers of elite sport systems face today. As this research showed, the two Benchmarking Subjects applied unexpected solutions for the delivery of some of the chosen Benchmarking Objects - and some of these practices appeared to be heavily linked to the organisational and cultural context of the investigated sport systems. Thus, it must be carefully evaluated for each process or structure, which is identified during a bench marking exercise, if it constitutes a transferable best practice which is applicable outside the organisational context of the respective Benchmarking Subject.

Our world is more technologically advanced and interdependent, risks are increasingly shared across local, regional and national boundaries and we are more culturally diverse than ever before. As a result, communities are increasingly confronted with emergencies and crises which challenge their social and economic stability. To be resilient, communities rely on services and employment provided by organisations, to enable them to plan for, respond to, and recover from emergencies and crises. However organisational and community resilience are two sides of the same coin; if organisations are not prepared to respond to emergencies and crises, communities too are not prepared.
Resilient organisations are also better poised to develop competitive advantage. However despite the potential business and performance rewards of becoming more resilient, organisations struggle to prioritise resilience and to allocate resources to resilience, which could be put to more immediate use. To enable organisations to invest in their resilience, the business case for resilience must be better than the case for new equipment or new staff.
This thesis develops a methodology and survey tool for measuring and benchmarking organisational resilience. Previous qualitative case study research is reviewed and operationalised as a resilience measurement tool. The tool is tested on a random sample of Auckland organisations and factor analysis is used to further develop the instrument. The resilience benchmarking methodology is designed to guide organisations’ use of the resilience measurement tool and its incorporation into business-as-usual continuous improvement.
Significant contributions of this thesis include a new model of organisational resilience, the resilience measurement tool, and the resilience benchmarking methodology. Together these outputs translate the concept of resilience for organisations and provide information on resilience strengths and weaknesses that enable them to proactively address their resilience and to develop a business case for resilience investment.

Texto completoResumen
Energisektorn står för nästan två tredjedelar av de antropogena växthusgasutsläppen i världen och utsläppen av koldioxid blir allt större. I Europeiska unionen står industrin för nästan 25 procent av den totala energianvändningen. Ett direktiv har tagits fram med krav på energieffektivisering där målet är att minska den totala energianvändningen med 20 procent till år 2020 och 27 procent till år 2030. En lag om energikartläggningar av stora företag är ett steg mot målet att minska energianvändningen. Inom industrisektorn råder det en problematik kring nyckeltal och kategorisering av slutlig energianvändning, vilket försvårar en jämförelse inom industrier och branscher samt en bedömning av den lönsamma potentialen att uppnå minskade koldioxidutsläpp och energieffektiviseringar. Hans Andersson Holding AB är ett återvinningsföretag och klassas som ett stort företag. Under år 2016 ska verksamheten energikartläggas av WSP Group AB, ett analys- och teknikkonsultföretag. I det här arbetet har en del av energikartläggningsarbetet genomförts samt har en intern och extern benchmarkinganalys utförts ur ett energieffektiviseringsperspektiv. Arbetets syfte har dels varit att genom en explorativ fallstudie vidareutveckla en metod för energi- kartläggning där nyckeltal används i processen och dels att genom en praktisk studie undersöka hur ett verktyg för dataanalys kan underlätta vid energikartläggning. Inledningsvis startade arbetet med en faktainsamling följt av energikartläggning med nyckeltal och användande av verktyget Norden Audit för dataanalys. Med all insamlad data och information har en analys av arbetet genomförts vilket resulterat i slutsatser. Energikartläggningen resulterade i åtgärdsförslag med energibesparingar på cirka 380 MWh/år, vilket motsvarar en besparing på cirka 285 500 kr/år i energikostnader. Analysen med verktyget Norden Audit har möjligen påvisat en tendens att tidsåtgången för dataanalys i energikartläggning är kortare med ett verktyg. Resultatet av den interna benchmarkinganalysen uteblev på grund av andra prioriteringar inom Hans Andersson Recycling AB och en utebliven energikartläggning. Den externa benchmarkinganalysen visade ett otrovärdigt resultat på grund av brister i jämförbarhet av slutlig energianvändning. Slutsatsen av arbetets resultat stärker tesen om problematiken kring kategorisering och jämförbara nyckeltal inom industrisektorn. Metoden för energikartläggning har möjlighet att vidareutvecklas genom att implementera jämförbara nyckeltal i rapporteringen, vilket på sikt skulle kunna få industrin mer energieffektiv. Då det krävs mer tid att implementera nyckeltal i energikartläggning kan det gynnas av att använda ett verktyg för dataanalys. För att säkert påstå att ett verktyg minskar tidsåtgången vid energikartläggningar krävs ytterligare studier med olika fall.The energy sector accounts for almost two-thirds of the anthropogenic greenhouse gas emission in the world and carbon dioxide emissions are increasing. In the European Union the industry accounts for almost 25 percent of the total energy use. To reduce the energy use a directive has been established to decrease the total energy use by 20 percent by year 2020 and by 27 percent by year 2030. One step to reach the goal is the law on energy auditing in large enterprises. In the industrial sector there is a problem with key performance indicators and categorization in energy end use which prevent comparing and to make estimations of the economic benefit potential to reach decreased carbon dioxide emissions and energy efficiency. Hans Andersson Holding AB is a large recycling enterprise. During 2016 WSP Group AB, a consultancy firm, is responsible to carry out an energy audit. In this project a part of the energy audit work is carried out along with an internal and external benchmarking analysis from an energy efficiency perspective. The goal with this project has been to further develop a method for energy auditing by implementing a key performance indicator in the reporting and also through a practical study investigate if a tool for data analysis could support an energy audit. The project started with a literature review and meetings followed by energy auditing with a key performance indicator. The tool Norden Audit was used during the analyze phase of the energy audit. With all the collected data an analysis was done, which resulted in conclusions. The energy audit resulted in energy efficiency proposals with a total energy saving potential of 380 MWh/year which translates in to about 285 500 SEK/year in energy cost savings. The study of the analysis tool Norden Audit possibly shows a tendency of less time required when using a tool for energy auditing. There was no result of the internal benchmarking due to a postponed energy audit and priorities within Hans Andersson Recycling AB. The external benchmarking showed an untrustworthy result because of flaws in the comparability of energy end use in the industry. The conclusion of the result strengthens the thesis on the problem of categorization and comparable key performance indicators in the industrial sector. The method for energy auditing has a possibility to be developed further by implementing key performance indicators in the reporting, which could support the industrial sector to be more energy efficient. To be able to state that a tool for data analysis in energy audits requires less time more studies in different cases is needed to be done.

Texto completoResumen
A maioria das organizações depende atualmente de algum tipo de infraestrutura computacional para suportar as atividades críticas para o negócio. Esta dependência cresce com o aumento da capacidade dos sistemas informáticos e da confiança que se pode depositar nesses sistemas, ao mesmo tempo que aumenta também o seu tamanho e complexidade. Os sistemas transacionais, tipicamente centrados em bases de dados utilizadas para armazenar e gerir a informação de suporte às tarefas diárias, sofrem naturalmente deste mesmo problema. Assim, uma solução frequentemente utilizada para amenizar a dificuldade em lidar com a complexidade dos sistemas passa por delegar sob outras organizações o trabalho de desenvolvimento, ou mesmo por utilizar soluções já disponíveis no mercado (sejam elas proprietárias ou abertas). A diversidade de software e componentes alternativos disponíveis atualmente torna necessária a existência de testes padronizados que ajudem na seleção da opção mais adequada entre as alternativas existentes, considerando uma conjunto de diferentes características. No entanto, o sucesso da investigação em testes padronizados de desempenho e confiabilidade contrasta radicalmente com os avanços em testes padronizados de segurança, os quais têm sido pouco investigados, apesar da sua extrema relevância. Esta tese discute o problema da definição de testes padronizados de segurança, comparando-o com outras iniciativas de sucesso, como a definição de testes padronizados de desempenho e de confiabilidade. Com base nesta análise é proposta um modelo de base para a definição de testes padronizados de segurança. Este modelo, aplicável de forma genérica a diversos tipos de sistemas e domínios, define duas etapas principais: qualificação de segurança e teste padronizado de confiança. A qualificação de segurança é um processo que permite avaliar um sistema tendo em conta os aspectos e requisitos de segurança mais evidentes num determinado domínio de aplicação, dividindo os sistemas avaliados entre aceitáveis e não aceitáveis. O teste padronizado de confiança, por outro lado, consiste em avaliar os sistemas considerados aceitáveis de modo a estimar a probabilidade de existirem problemas de segurança ocultados ou difíceis de detectar (o objetivo do processo é lidar com as incertezas inerentes aos aspectos de segurança). O modelo proposto é demonstrado e avaliado no contexto de sistemas transacionais, os quais podem ser divididos em duas partes: a infraestrutura e as aplicações de negócio. Uma vez que cada uma destas partes possui objetivos de segurança distintos, o modelo é utilizado no desenvolvimento de metodologias adequadas para cada uma delas. Primeiro, a tese apresenta um teste padronizado de segurança para infraestruturas de sistemas transacionais, descrevendo e justificando todos os passos e decisões tomadas ao longo do seu desenvolvimento. Este teste foi aplicado a quatro infraestruturas reais, sendo os resultados obtidos cuidadosamente apresentados e analisados. Ainda no contexto das infraestruturas de sistemas transacionais, a tese discute o problema da seleção de componentes de software. Este é um problema complexo uma vez que a avaliação de segurança destas infraestruturas não é exequível antes da sua entrada em funcionamento. A ferramenta proposta, que tem por objetivo ajudar na seleção do software básico para suportar este tipo de infraestrutura, é aplicada na avaliação e análise de sete pacotes de software distintos, todos alternativas tipicamente utilizadas em infraestruturas reais. Finalmente, a tese aborda o problema do desenvolvimento de testes padronizados de confiança para aplicações de negócio, focando especificamente em aplicações Web. Primeiro, é proposta uma abordagem baseada no uso de ferramentas de análise de código, sendo apresentadas as diversas experiências realizadas para avaliar a validade da proposta, incluindo um cenário representativo de situações reais, em que o objetivo passa por selecionar o mais seguro de entre sete alternativas de software para suportar fóruns Web. Com base nas análises realizadas e nas limitações desta proposta, é de seguida definida uma abordagem genérica para a definição de testes padronizados de confiança para aplicações Web.Most organizations nowadays depend on some kind of computer infrastructure to manage business critical activities. This dependence grows as computer systems become more reliable and useful, but so does the complexity and size of systems. Transactional systems, which are database-centered applications used by most organizations to support daily tasks, are no exception. A typical solution to cope with systems complexity is to delegate the software development task, and to use existing solutions independently developed and maintained (either proprietary or open source). The multiplicity of software and component alternatives available has boosted the interest in suitable benchmarks, able to assist in the selection of the best candidate solutions, concerning several attributes. However, the huge success of performance and dependability benchmarking markedly contrasts with the small advances on security benchmarking, which has only sparsely been studied in the past. his thesis discusses the security benchmarking problem and main characteristics, particularly comparing these with other successful benchmarking initiatives, like performance and dependability benchmarking. Based on this analysis, a general framework for security benchmarking is proposed. This framework, suitable for most types of software systems and application domains, includes two main phases: security qualification and trustworthiness benchmarking. Security qualification is a process designed to evaluate the most obvious and identifiable security aspects of the system, dividing the evaluated targets in acceptable or unacceptable, given the specific security requirements of the application domain. Trustworthiness benchmarking, on the other hand, consists of an evaluation process that is applied over the qualified targets to estimate the probability of the existence of hidden or hard to detect security issues in a system (the main goal is to cope with the uncertainties related to security aspects). The framework is thoroughly demonstrated and evaluated in the context of transactional systems, which can be divided in two parts: the infrastructure and the business applications. As these parts have significantly different security goals, the framework is used to develop methodologies and approaches that fit their specific characteristics. First, the thesis proposes a security benchmark for transactional systems infrastructures and describes, discusses and justifies all the steps of the process. The benchmark is applied to four distinct real infrastructures, and the results of the assessment are thoroughly analyzed. Still in the context of transactional systems infrastructures, the thesis also addresses the problem of the selecting software components. This is complex as evaluating the security of an infrastructure cannot be done before deployment. The proposed tool, aimed at helping in the selection of basic software packages to support the infrastructure, is used to evaluate seven different software packages, representative alternatives for the deployment of real infrastructures. Finally, the thesis discusses the problem of designing trustworthiness benchmarks for business applications, focusing specifically on the case of web applications. First, a benchmarking approach based on static code analysis tools is proposed. Several experiments are presented to evaluate the effectiveness of the proposed metrics, including a representative experiment where the challenge was the selection of the most secure application among a set of seven web forums. Based on the analysis of the limitations of such approach, a generic approach for the definition of trustworthiness benchmarks for web applications is defined.

Texto completoResumen
The Hypertext Transfer Protocol (HTTP) is one the foundations of the modern Internet. Because HTTP servers may be subject to unexpected periods of high load, developers use HTTP benchmarking utilities to simulate the load generated by users. However, many of these tools do not report performance details at a per-client level, which deprives developers of crucial insights into a server's performance capabilities.
In this work, we present ink, an HTTP benchmarking tool that enables developers to better understand server performance. ink provides developers with a way of visualizing the level of service that each individual client receives. It does this by recording a trace of events for each individual simulated client. We also present a GUI that enables users to explore and visualizing the data that is generated by an HTTP benchmark. Lastly, we present a method for running HTTP benchmarks that uses a set of distributed machines to scale up the achievable load on the benchmarked server.
We evaluate ink by performing a series of case studies to show that ink is both performant and useful. We validate ink's load generation abilities within the context of a single machine and when using a set of distributed machines. ink is shown to be capable of simulating hundreds of thousands of HTTP clients and presenting per-client results through the ink GUI. We also perform a set of HTTP benchmarks where ink is able to highlight performance issues and differences between server implementations. We compare servers like NGINX and Apache and highlight their differences using ink.Master of Science
The World Wide Web (WWW) uses the Hypertext Transfer Protocol to send web content such as HTML pages or video to users. The servers providing this content are called HTTP servers. Sometimes, the performance of these HTTP servers is compromised because a large number of users requests documents at the same time. To prepare for this, server maintainers test how many simultaneous users a server can handle by using benchmarking utilities. These benchmarking utilities work by simulating a set of clients. Currently, these tools focus only on the amount of requests that a server can process per second. Unfortunately, this coarse-grained metric can hide important information, such as the level of service that individual clients received. In this work, we present ink, an HTTP benchmarking utility we developed that focuses on reporting information for each simulated client. Reporting data in this way allows for the developer to see how well each client was served during the benchmark. We achieve this by constructing data visualizations that include a set of client timelines. Each of these timelines represents the service that one client received. We evaluated ink through a series of case studies. These focus on the performance of the utility and the usefulness of the visualizations produced by ink. Additionally, we deployed ink in Virginia Tech's Computer Systems course. The students were able to use the tool and took a survey pertaining to their experience with the tool.

A indústria de software tornou-se, em apenas algumas décadas de existência, um setor vital para o mundo. Porém, os problemas pelos quais teve que passar, principalmente relacionados à qualidade de seus produtos e processos, fizeram surgir diversos modelos e normas para a disseminação de melhores práticas de engenharia de software, iniciativas e estudos em busca da qualidade, sempre focados mais nos aspectos técnicos e pouco nos aspectos empresariais. O presente trabalho teve como objetivo o desenvolvimento de um método para realização de benchmarking em empresas da indústria de software, consistindo num processo de avaliação por indicadores de práticas e resultados (performance) e num modelo de relatório de análise de resultados. O método baseia-se em melhores práticas referenciadas em normas e modelos do setor de software, que tratam sobre engenharia e qualidade de produtos e processos de software, bem como em indicadores de gestão organizacional, de projetos, de inovação e de qualidade, adaptados dos métodos Benchstar e Benchmarking Industrial, amplamente utilizados pelo Instituto Euvaldo Lodi de Santa Catarina (IEL/SC) em indústrias tradicionais. O modelo de ferramenta desenvolvido foi aplicado, em escala piloto, em três empresas de software de Santa Catarina, que apresentaram resultados distintos devido a suas diferentes características. No entanto, alguns pontos comuns foram verificados, como as deficiências nas práticas em gestão da inovação e gestão organizacional ou os pontos fortes na performance em gestão da qualidade e organizacional. Os resultados permitiram validar o potencial do método para a avaliação e comparação das empresas do setor de software. The software industry has become, in few decades of existence, a vital segment for the world. But the problems for which he had to overcome, mainly related to the quality of their products and processes, have led to many models and standards for the dissemination of best practices of software engineering, several initiatives and studies in search of quality, focused more on technical aspects than on the business one. This work was aimed at developing a method for benchmarking companies in the software industry, consisting of a assess process through practices and performance indicators, and of a model report to results analysis. The method is based on best practices referenced in models and standards of software industry, about engineering and quality of software products and processes as well as indicators of organizational, project, innovation and quality management, adapted from the Benchstar and Benchmarking Industrial methods, widely applied by Euvaldo Lodi Institute of Santa Catarina (IEL/SC) in traditional industries. The developed tool was applied, in pilot scale, in three software companies of Santa Catarina, presenting different results due to their different characteristics. However, some common points have been verified, as the deficits in practice of innovation management and organizational management, as well as the strengths in quality and organizational management performance. The results validate the model as a potential method for evaluating and comparing companies in the software industry.

Bakgrund Benchmarking är ett populärt styrverktyg men studierhar visat att benchmarking inte anses som ett likaeffektivt förbättringsverktyg som andra styrverktyg,vilka kritiska faktorer som ligger bakom enframgånsrik benchmarking bör då undersökas. Efter en genomgång av tidigare studier fann vi dessutom attbrister finns gällande vetskapen hur användandet avintern benchmarking upplevs. Få studier har gjortsinom detaljhandeln där intern benchmarking tycksvara användbart. Syfte Syftet med studien är att få en större kunskap kringupplevelserna av intern benchmarking inomdetaljhandeln. Studien syftar även till att redogöra förvad det är som ligger bakom en framgångsrik internbenchmarking. Frågeställningar Hur upplevs intern benchmarking inom detaljhandeln? Vilka är de kritiska faktorerna för framgångsrik internbenchmarking? Metod Studien utgörs av en kvalitativ ansats bestående av 2 intervjuer med företagsledning och 5 intervjuer medvaruhuschefer. Studien har även en kvantitativ delsom består av en enkätundersökning med enpopulation på 75 personer. Slutsats Studiens slutsats är att intern benchmarking upplevs som motiverande, stimulerande, användbart i dendagliga verksamheten samt ökar förståelsen förorganisationen. Kritiska faktorer bakom enframgångsrik intern benchmarkingprocess är en tydlig process, utbildning, tillgång till data, ett bra forum förkommunikation och högt deltagande av anställda.Background Benchmarking is a popular managament tool butstudies have shown that benchmarking is notconsidered as an effective management tool as othermanagement tools, what the critical factors behind asuccessful internal benchmarking should therefore belooked into further. We also found, after reviewingformer studies, that there are lack of informationabout the experience of using internal benchmarking. Only a few studies have been done in retail whereinternal benchmarking seems useful. Aim The aim with the studie is to get more knowledgeabout the experiences of internal benchmarking inretail. The study also aims to state the critical factorsbehind a successful internal benchmarking. Research questions What is the experience of internal benchmarking inretail? What are the critical factors behind a successfulinternal benchmarking? Methodology The study has a qualitative approach and consists of 2 interviews with management and 5 interviews withstore managers. The studie also has an quantitativeapproach that consists of a survey with a populationof 75 people. Conclusion The conclusion of the study is that internalbenchmarking are experienced as motivating,stimulating, useful in the daily business and alsoincreases the understanding of the organization. Critical factors behind succescfull internalbenchmarking process are a clear process, education,access of data, a good forum for communication andhigh participation rate of the employees.

Texto completoResumen
Many maintenance policies have been proposed for refreshing a warehouse. The difficulties of selecting an appropriate maintenance policy for a specific scenario with specific source characteristics, user requirements etc. has triggered researcher to develop algorithms and cost-models for predicting cost associated with a policy and a scenario. In this dissertation, we develop a benchmarking tool for testing scenarios and retrieve real world data that can be compared against algorithms and cost-models. The approach was to support a broad set of configurations, including the support of source characteristics proposed in [ENG00], to be able to test a diversity set of scenarios.

Texto completoResumen
Catastrophic Forgetting is a behavior seen in artificial neural networks (ANNs) when new information overwrites old in such a way that the old information is no longer usable. Since this happens very rapidly in ANNs, it leads to both major practical problems and problems using the artificial networks as models for the human brain. In this thesis I will approach the problem from the practical viewpoint and attempt to provide rules, guidelines, datasets and analysis methods that can aid researchers better analyze new ANN models in terms of catastrophic forgetting and thus lead to better solutions. I suggest two methods of analysis that measure the overlap between input patterns in the input space. I will show strong indications that these measurements can predict if a back-propagation network will retain information better or worse. I will also provide source code implemented in Matlab for analyzing datasets, both with the new suggested measurements and other existing ones, and for running experiments measuring the catastrophic forgetting.

Tereci, Aysegul. "Energy Benchmarking Method For Urban Settlements". Phd thesis, METU, 2012. http://etd.lib.metu.edu.tr/upload/12614276/index.pdf.
Texto completoResumen
The aim of this study was developing an energy benchmarking method for urban quarters in order to design or manage the energy efficiently at urban scale. Rational implementation of energy efficiency strategies for the urban settlements can be possible with the comprehensive building stock models which have the ability to estimate and evaluate the energy demand of the building stock together with surrounding urban structures.
The research initially focused to determine the factors which have an influence on the urban energy performance and rating, labeling, benchmarking systems used for evaluation of the energy performance. The field of study has narrow down to residential urban quarters which is approximately 70 % of the building stock. It has been considered surrounding attributes, building properties and occupant behavior. The results of the
measurements from casestudy area were evaluated with regresional analysis in order to understand which factors have influence on energy performance. Artificial representative residential settlements were configured in that some of the factors were not possible to consider or evaluate with casestudy data. These representative residential settlements were evaluated with EnergyPlus simulation program and the results were compared with each other for forming a benchmarking method.
The simulation results shows that density of the area and building envelope properties have significant effect on the urban energy performance. In order to use these benchmarking results, simulations were applied to the web tool. This urban energy benchmarking method provide the quantified energy performance of the different settlement types for urban designers and urban energy planners enabling them to estimate the urban energy requirement without socio economic context.

Texto completoResumen
An assortment of 1,551 retail cuts were purchased from eleven cities across the
United States to study their physical and chemical composition. Information with regard
to external fat thickness, package weight, price per kilogram, and total package price
were collected at the retail store. Cuts were purchased and later dissected into four
different separable components, separable lean, external fat (carcass and cut), seam
(intermuscular) fat, and bone and heavy connective tissue. Chemical fat analyses were
conducted on the separable lean component of each dissected cut.
Dissection data showed that cuts originating from the round had the highest
means for separable lean percentages, resulting in the lowest means for separable fat
percentages. Cuts from the rib were found to have the highest separable fat percentage
means, thus the lowest separable lean percentage means.
Chemical fat data mirrored dissection data, with round cuts having the lowest
means for percent extractable fat for the separable lean (only) and rib cuts producing the
highest means. In general, ground beef packages had a lower percentage of extractable
fat than the fat percentage that was declared on the retail package label.
This study was designed to acquire data on cuts presently available at the retail
level and compare their composition to data presented in the National Nutrient Database for Standard Reference. It must be noted that separable fat percentages are not available
for many of cuts sampled for this survey. Additionally, data reported in the Nutrient
Database encompasses only retail cuts trimmed to 1.25 cm, 0.6 cm, 0.3 cm, and 0.0 cm.
Cuts from this study consistently had fat thickness measurements between 0.0 cm and
0.3 cm; thus, there is no nutritional information in the Nutrient Database for beef cuts
trimmed to these levels.

Texto completoResumen
Web services are often used for retrieving data from servers providing information of different kinds. A data providing web service operation returns collections of objects for a given set of arguments without any side effects. In this project a web service benchmark (WSBENCH) is developed to simulate the performance of web service calls. Web service operations are specified as SQL statements. The function generator of WSBENCH converts user specified SQL queries into functions and automatically generates a web service. WSBENCH can automatically both generate and deploy web the service operations for exported functions. Furthermore WSBENCH supports controlled experiments, since users can control the characteristics of web service operations such as scalability of data and delay time. The database used in this project is generated by the Berlin Benchmark database generator. A WSBENCH demo is built to demonstrate the functionality. The demo is implemented as a JavaScript program acting as a SOAP client, directly calls WSBENCH services from a web browser. Users can make a web service request by simply providing the web service operation’s name and parameter values list as the input. It makes the WSBENCH very simple to the use.

Texto completoResumen
Over the years different algorithms have been developed to step-by-step solve parts of the Rubik's cube until finally reaching the unique solution. This thesis explores two commonly known beginner algorithms for solving Rubik’s cube to find how they differ in solving speed and amount of moves. The algorithms were implemented and run on a large amount of scrambled cubes to collect data. The results showed that Layer-by-layer with daisy algorithm had a lower average amount of moves than the Dedmore algorithm. The main difference in amount of moves lies in the steps that solve the last layer of the cube. The Layer-by-layer with daisy algorithm uses only one-seventh of the time-consuming operations that Dedmore algorithm uses, which concludes that it is more suitable for speedcubing.Över åren har ett antal olika algoritmer utvecklats för att steg-för-steg lösa delar av Rubik's kub för att till sist komma fram till den unika lösningen. Denna rapport utforskar två allmänt kända nybörjaralgoritmer för att lösa Rubik's kub, för att finna hur dem skiljer sig åt i tid samt antal operationer för att nå lösningen. Algoritmerna implementerades och kördes på ett stort antal blandade kuber för att samla data. Resultatet visar att Lager-för-lager med daisy algoritmen hade ett lägre genomsnittligt antal förflyttningar jämfört med Dedmore algoritmen. Den största skillnaden i antalet förflyttningar ligger i stegen som löser sista lagret av kuben. Lager-för-lager med daisy algoritmen använder bara en sjundedel av de mest tidskrävande förflyttningarna jämfört med Dedmore algoritmen, slutsatsen av detta är att Lager-för-lager med daisy algoritmen är bättre lämpad för lösning av kuben på tid.

Texto completoResumen
The management of large capital improvement construction programs involves the efforts of both internal staff and external service providers. An understanding of how construction programs are managed, either through internal or external staff, is essential in tracking future trends and determining improvements and best practices in the management process. To address this need a survey was developed by a focus group of industry professionals. The survey was distributed to the membership of a number of professional organizations that represented owners within the construction industry. The survey attempted to determine both the current status of managing a construction program throughout a broad range of demographic characteristics (including the definition of program management) and the hiring of an external program manager. The survey and subsequent analysis that focused on the management of a construction program examined the following key points: role of a program manager, internal capabilities, outsourcing, sourcing strategy, and management costs. The survey and subsequent analysis that focused on hiring an external program manager examined: program management fees, type of firms used in managing a construction program, factors considered when hiring a program manager, and organizational structure. The results of the survey have also been segregated by public and private organizations to denote any differences in the management of public and private construction programs. A key contribution of this research was determining the percentage of outsourcing within each phase of the construction process and the number of service providers considered in the selection process. Also, a multifaceted definition of program management was developed from the research for use in clarifying the concept of program management within construction.

Texto completoResumen
Benchmarking corresponds to a combination of two sources of information on a given variable. In many situations, the problem consists of combining a series of frequent data with a series of less frequent but more accurate data for producing more accurate estimates of the former series. For example, estimates of population characteristics are derived from the last census and researchers re-estimate the values for the time gap between two censuses using more regular information. In what follows we focus in the .' problem of benchmarking monthly data with annual estimates; then, the benchmarking consists of forcing the sum of the monthly signals to equal the signal of the benchmark. Alternative estimators have been proposed in the literature for benchmarking. When the adjusted series agrees exactly with these benchmarks, the benchmarking is called binding. The binding process is implemented by setting the variance of. the annual survey errors to zero. However, it is necessary to account for the variance of the annual survey errors when computing the variances of the benchmarked estimators. In this thesis, we develop the theoretical expression of the correct variance as well as an expression for the excess in the variance due to the binding process. The results are extended to the most known bepchmarking methods proposed in the literature. An application to business surveys used for official statistics in the UK is presented, illustrating some particular issues regarding the state space modelling. Finally, the problem of how to prepare tabular data classified by attributes as columns and points in time as rows is analyzed. This multivariate extension of the benchmarking problem distinguishes two basic type of problems: when only marginal totals are available (contemporaneous disaggregation) and when the aggregates do not correspond with the sum of the disaggregated values by year and/or by attributes (reconciliation). The scope of this thesis is based basically in a state space model approach.

Texto completoResumen
Community Health Centers (CHCs), designed to provide accessible and affordable health care services to low-income families, were first funded by the Federal Government as part of the War on Poverty in the mid-1960s. Improving healthcare organizational performance efficiency is paramount. It is an especially pressing need for CHCs' because they carry a disproportionate burden of caring for the uninsured within limited budgets. Prior studies suffer from conceptual and methodological limitations. A longitudinal multivariate analysis of factors influencing the performance of CHCs is needed. The purpose of this study is to benchmark CHC performance in terms of technical and cost efficiency, and examine factors that affect its variation. A theoretically grounded non-experimental study design is used, with five waves of panel data from 493 CHCs for the years 2000 through 2004. This study found that data mining and predictor tree analysis of factors influencing the variation in CHCs' technical and cost efficiency yielded inconsistent results. A declining trend in technical efficiency scores over the five-year study period was observed. Based on growth curve modeling, the three factors that influenced technical efficiency at the initial period of the study are: the percentages of Medicare, Medicaid, and Hispanic population being served by the CHCs. The five factors that positively influenced the variation in cost efficiency at the initial period were: the initial score of technical efficiency, the percentage of Hispanic patient population, staffing mix (ratio of providers to total staff), pay mix (ratio of federal grant dollars to total revenue), and percentage of Medicare-eligible. The initial cost-efficiency score and the initial technical efficiency score are negatively associated with the growth trend of technical efficiency. The initial level of technical efficiency is not statistically significantly associated with the growth trend of cost efficiency. The two factors influencing the growth trend of cost efficiency are the growth trend of technical efficiency (with a positive influence) and the initial level of cost efficiency (with a negative influence). Analysis of the effects of contextual and organizational-structural variables on the technical efficiency and cost efficiency of community health centers found that the explanatory power of the predictors is much greater for cost efficiency than for technical efficiency. The study lends support to contingency theory and confirms the independent and additive influences of contextual and organizational predictors on efficiency. Irrespective of the efficiency measures, contextual factors have much more influence on CHCs' efficiency than design (organizational structural) factors do. The three study hypotheses supported by multivariate analysis are: technical efficiency is associated with contextual factors and organizational factors; cost efficiency is associated with contextual factors and organizational factors; and technical efficiency positively affects cost efficiency.Ph.D.
