Xinyuan, Luo. "DSP Platform Benchmarking : DSP Platform Benchmarking". Thesis, Linköping University, Department of Electrical Engineering, 2009. http://urn.kb.se/resolve?urn=urn:nbn:se:liu:diva-19258.
Testo completoBenchmarking 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.
Winberg, Ulf. "DRAM Controller Benchmarking". Thesis, Computer Engineering, 2009. http://urn.kb.se/resolve?urn=urn:nbn:se:liu:diva-19190.
Testo completoSince 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.

Testo completoDenna 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.

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.

Testo completoThis 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.

Testo completoRehman, Shafqat Ur. "Benchmarking in wireless networks". Nice, 2012. http://www.theses.fr/2012NICE4003.
Testo completoThe 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
Larsson, Petter, e Gustaf Rudbeck. "Wave Energy Concept Benchmarking". Thesis, KTH, Maskinkonstruktion (Inst.), 2021. http://urn.kb.se/resolve?urn=urn:nbn:se:kth:diva-298841.
Testo completoThis 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. However, an OWC rarely consists of a single air chamber but often in a construction with several air chambers with separate turbines to increase the power.

Testo completoTitel: 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.

Testo completoMeier, A. M. "Randomized Benchmarking of Clifford Operators". Thesis, University of Colorado at Boulder, 2013. http://pqdtopen.proquest.com/#viewpdf?dispub=3592339.
Testo completoRandomized 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.

Testo completoThe 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.

Testo completoMost 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.

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.

Testo completoBackground 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.

Testo completoMany 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.

Testo completoCatastrophic 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.

Testo completoÖver 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.
