Processchemaläggare för mångkärniga processorer ? Fördelning av minnesbelastning i NUMA-system

For systems with multicore processors contention for shared resources is a problem that occurs when several memory-intensive processes are executed in parallel within the same memory domain. This contention has a direct influence on the performance of the system and is a complex problem that has been recognized for a long time. An attractive and actively studied way to minimize this problem is by using a process scheduler adapted to allocate processor cores in a way such that contention for shared resources is minimized.With the introduction of multicore NUMA-systems (Non-Uniform Memory Access) the situation has become even more complex. In these systems the access time for processor cores to different memory domains vary depending on factors such as distance and load. Thus, the process scheduler also has to consider where the memory of each process is placed to minimize the distance and balance the load on each memory domain.This report presents a user-level process scheduler for a NUMA-system based on the multicore processor Tilera TILEPro64.

Jämförande simulering och modellering av framtida järnvägars elenergiförsörjning

In this thesis, the Train Power System Simulator (TPSS) has been compared and verified with the commercial simulator TracFeed® Simulation (TracFeed). The basis for the comparison was a given part of the Swedish railway system, with steel transportation trains. Primarily, emphasis was placed on running time and energy consumption in simulation results. Two transformer systems were analyzed, booster and auto transformers. The high voltage transmission line, parallel to the railroad track, was disconnected in some simulations.

Evaluation of Xilinx System Generator

This Master?s Thesis is an evaluation of the software Xilinx System Generator (XSG) and blockset for Matlab. XSG is a module to simulink developed by Xilinx in order to generate VHDL code directly from functions implemented in Matlab. The evaluation was made at Saab Avionics AB in Järfälla, north of Stockholm. In order to investigate the performance of this new module XSG to simulink, a model of a frequency estimator often used in digital radar receivers were implemented in Matlab using XSG.

Skyddsvillkor för areella näringar i 3 kap. FBL: En rättfallsstudie

In this report a study is carried out with the aim to identify added values of EPC projects implemented in schools in order to increase the interest of EPC projects on the market. The report examines how the planned maintenance, supervision, maintenance and corrective maintenance is affected, how insurance premiums and terms are affected, the indoor environment and how the tasks of the operating staff is changing. A literature study of energy savings, energy use in schools, maintenance and insurance as well as how energy efficiency improvements are related to the Swedish environmental objectives has been made. Visits were carried out in Ludvika, interviews were also carried out with operation technicians and local strategists in Ludvika as well as employees of insurance companies.Schools often have neglected maintenance and problems with ventilation and indoor environment. Schools also have a large energy saving potential due to their low utilization, mainly because they are empty parts of the year.

Interaktiv konst : Åtta ungdomars möte med och skapande av interaktiv konst

AbstractEffective January 1, 2005 publicly listed companies were obliged to adopt a new financialreporting standard (IFRS/IAS). The objective of IFRS/IAS was to increase transparency andcomparability in financial reports between companies. The authors have chosen to write aboutIAS 40 where the accounting treatment for investment property and related disclosurerequirements are regulated.The purpose of this thesis is to investigate potential effects of valuation of investmentproperty at fair market value for real estate companies at times when market price decreasesand to investigate what an acceptable difference for the valuation could be.To fulfil this purpose the authors have chosen a qualitative method interviewing accountants,property analysts and a credit analyst to obtain a deeper understanding of the problem. Basedata for the thesis have been collected during meetings, telephone interviews and e-mails.Additional data was collected from public available sources such as the internet, relevantprofessional magazines and professional newsletters. The authors have designed a modelshowing how Income and Balance Sheet statements are influenced by changed valuation ofinvestment property.

Just In Time : Effektivisering av materialflöden med hjälp av principer från Inventory Management och Production Management

AbstractManagement is a field that started getting attention in the beginning of the 20th century by Frederick Taylor. His publication is called the Principles of Scientific Management and is based on the principles of using scientific methods to find the best way of conducting each operation within a production facility. Many of Taylor?s principles may appear obsolete today but the matter of an effective material flow is still highly current. Efficiency is the relationship between the input into an operation and its result.

Voice onset time hos svenska förskolebarn : Ett utvecklingsperspektiv

Voice onset time (VOT) är en akustisk tidsparameter som speglar den talmotoriska kontrollen. VOT anses vara det mest tillförlitliga akustiska tecknet på om en klusil är tonande eller tonlös.Syfte: att undersöka och jämföra VOT hos barn i åldrarna 3, 4 och 5 år samt jämföra med tidigare publicerade svenska vuxenvärden.Metod: 83 barn (51 flickor; 32 pojkar) ljudinspelades vid produktion av minimala par för de svenska klusilerna.Resultat: medelvärden för VOT minskade genomgående med åldern. Signifikanta skillnader erhölls mellan 3- och 5-åringarna för ljuden /t k b g/ samt gällande användandet av förton för tonande klusiler. Jämförelser med vuxenvärden visade att vuxna i högre utsträckning hade förton för de tonande ljuden och kortare VOT för de tonlösa ljuden än de, i föreliggande studie, deltagande barnen. Inga signifikanta könsskillnader påträffades.Resultaten av föreliggande studie kan användas som referensmaterial vid bedömning av barn med talmotoriska störningar..

Etiken och det heliga En studie av relationen mellan etiken och det heliga i Giorgio Agambens och Emmanuel Levinas filosofier

The first aim of this study is to discuss and try to understand the relationship between the holy andethics, and more specifically how it can be understood, which is the critical question that I haveformulated, in Giorgio Agamben?s and Emmanuel Levinas? philosophies. The second, moreconstructive aim is to discuss whether the holy can be understood as something good or problematicin relation to the society.Rooted in philosophy of religion and ethics, I have first tried to discuss how the holy has beenunderstood in the philosophy of phenomenology and in the texts of Rudolf Otto, Mircea Eliade andEspen Dahl. The holy has in the history been understood as something central in religions, and hasalso not been connected to the idea of ethics. Recently it has also been critized ? by Dahl ? for notbeing so pure as first thought of.In Levinas texts the holy has been understood as something differentiated through his distiction,in the Talmudic reading ?Desacralization and Disenchantment?, between the holy, which can beseen as something pure, and the sacred which can been seen as something impure and a form ofdegenerated holiness.

Thisfollowing the premiere of the children?s film ?Liten Skär och alla små brokiga?.Stina Wirsén is an established and well-acclaimed name in children?s literature. ?LillaHjärtat?, a jet-black doll, had become one of many popular characters in her books.

Analys av faktorer som påverkar interna leveransledtider : Dimensionering av lager

It is becoming increasingly important for companies to meet customer demands due to intense competition in today's global market, that forcing companies to improve their offerings and become better at managing their supply chain (Shen et al., 2006).  Long lead times can be reduced by using different methods and strategies shows various researches. Lead times occur in the planning, production, inventories and handling of products (Treville et al., 2003).The aim of the study is to develop a method to analyze the factors that affect the length of internal delivery lead time in manufacturing companies. The method also included suggestions for reducing delivery lead-time to internal customers.The main factors that influenced the length of the on delivery lead times has summarized to make a selection among the factors that can have the most significant impact. The selected elements will be used as a method to analyze how these areas affect a company?s length on internal delivery lead times.The study shows that the causes of the long delivery lead times was the location of the customer order point, uncertain forecasts, long material and production planning time, and long waits in the production and storage.The delivery lead time, according to this report?s suggested improvements reduced by centralizing CODP and makes more reliable forecasts.

Ställtidsreducering med hjälp av SMED i pressgjuterianläggningar

To maintain production in high salaries countries and strength in competition against other companies, it is today more important than ever to maximize production, offer a wide spectra of products and be able to deliver on the customers desire of shorter and shorter delivery time. Flexible production and short time spent on die changes is vital to achieve these desires. The interest for die changeover time reduction grew in the same pace as the demand for increased product variety grew. SMED as a method of reducing time spent on die changeovers were developed in between 1950-1970, by the Japanese Shigeo Shingo.The purpose of this thesis work has been to investigate the result of SMED in a die casting facility, and compare the result from it with the result considering time spent on die changeovers when investing in new equipment. The goal is to implement a thorough investigation by using the SMED method at Tenhults Pressgjuteri AB and make a brochure that have to be simple to understand, in purpose to draw interest to the advantages of using SMED as a method.Commissioned by the Swedish foundry association Swecast, the work has been carried out by studying die changeovers at Tenhults Pressgjuteri AB, where filming and interviews with the operators have been included in the analysis.

Ball and beam

The main purpose of this bachelor thesis is to create a product in the form of a database that can be used for cost estimates of equipment within bio refineries. Through interviews and literature searches the key components and their costs were identified. The database was constructed in Microsoft Excel with different tabs for different categories of components; these tabs are further divided into three parts: one part with costs, one part with calculations and an information part. Most of the part with costs contains the expenses found in scientific papers during the literature study, the calculating part converts different capacities according to user preferences and the currency to euro (?) from 2010 and the information part consists of references and information about what is included in the cost.The database is a good tool for making cost estimates for bio refineries.

Automatgenerering av transaktionshanteringsprocedurer

In a database environment, when you create or alter tables you often want to have a basic interface for standard operations such as insert, delete and update. This thesis report covers an analysis of what programs there are on the market for generating such interfaces and compares them against the demands of a real company. The analysis showed that none of the programs were completely meeting the requirements and therefore an own implementation of an interface generating program was created. The result is a PL/SQL program capable of generating files, storing them in a version handling system and executing the files into the database..

Projektledning : En studie om en effektiviserad projektledningsmetod till TS Produktion

The term "Project" have become a growing work model that exist in almost all bransches. A project is a work effort made over a finite period of time with a start and a finish to create a unique product, service, or result. Science shows that time limitation has an impact on humans to perform under pressure, which challanges the contributor to deliver. This report contains an examination about project management, both coming from scientific results and an external business. The point of this study is to bring ideas of improvement, which can make the work method more effective in this company..

Dagens Agora : En kritisk granskning av Internets möjligheter och begränsningar

The time we live in now is significant for its many ways of spreading information- it is indeed the era of communication. The Internet is the main reason for this evolution, where you can reach out to any corner in the world in less then a second. Information is flowing over us and we get more and more used to being in a constant accessible state. The individual might spread his own word as he wishes. From a democratic point of view this should give a great opening for everyone into the public spheer.
