There are some key elements which distinguish a general operating system, such as Linux, from a Real Time operating system, such as OSE. The later belongs to the category of soft Real Time systems while Linux is a general operating system, with significantly improved real time properties after version 2.6. These improvements make it interesting to compare the two systems.When comparing two operating systems, there are a number of issues which have to be considered. One way to measure the performance of the systems is by studying the time consumption for the same functionality and hardware.During the study, the items that appeared as the most important for the performance of the systems, were: process primitives, system primitives, interprocess communication, context switches and interrupt latency.This work demonstrates that it is possible and reasonable to do performance testing on two different operating systems. The implemented tests cover a number of basic functionalities, which appeared to be the most crucial ones for the performance of the systems..

 Performance appraisals- a study of the performance appraisals significance as a tool for development in the public sector.Anders Larsson and Åsalill OlssonPerformance appraisals have been given a central role in leading businesses in the public sector and are seen as a tool to create development opportunities and achieve better results. This has resulted that performance appraisal in many organizations takes up capacity and time. This was the starting point of our interest to study whether the time spent on performance appraisals effectively pays for itself in the organization, in other words whether the effects expected actually are achieved. The paper examines first line managers` views on staff appraisal purposes and effects of a function within the Landstinget. The survey design, methodology and transaction are of qualitative and quantitative method with three different sources: literature review of previous research, interviews with first line managers in Landstinget Västmanland and the results from an employee satisfaction survey conducted on behalf of Landstinget Västmanland.

At the Division of Electricity at Uppsala University there is an experimental rig forhydroelectric generators. The experimental rig?s vital part is a 12-pole synchronousmachine, whose electrical characterizing parameters (resistances, inductances andtime constants) are unknown. The aim of this thesis is to characterize the machine inits current state by perform a Standstill Frequency Response (SSFR) test. From theanalysis of the measurement data, which is a part of the test, a set of basic parametershave been received.

In game development, performance is everything and the Playstation 3 provides a unique platform for utilizing parallelization of code to achieve extremely high performance. In this master?s thesis the issue of animation with smooth skinning is migrated from being a GPU process to becoming a parallelized and 358% faster process. This method is incorporated in an existing commercial game engine and integrated in a currently in development title for the Playstation 3. An in-depth study covers parallel processors, the CELL processor, used in the Playstation 3, and how contemporary industry leading game developers are utilizing the same unique architecture to increase their own games? performance..

An attempt were made to record the 1st movement of Beethoven?s Op. 57, with the objective of performing it as close to Beethoven?s will as possible, in the tradition of the ?historically informed performance? movement.The result of evaluating source material rendered a list of the most relevant material for this study, and hopefully that might prove useful for other studies with similar objective concering HIP and composer-intention based ?autenticity?.However, Beethoven?s will was only vaguely captured in the limited source material accounted for in this study, rendering it moderate-to-small reliability. It?s probably possible to achieve a higher degree of goal achievement, given more time and through the utilization of music psychology to further extrapolate the detailed parameters of Beethoven?s presumed extramusical will.The recording made was not to my satisfaction and has strengthened my view that the interpreter should take council from the collected knowledge of scholarly sources but must ultimately remain free in whether and how to utilize that knowledge.Lastly, I?ve measured the bpm in the resulting recording with a error margin of ±0,02 s.

Bakgrund: Under 1900-talet skedde flera teknologiska framsteg och Relevance Lost-debatten förändrade synen på den traditionella ekonomistyrningen. De två målstyrningssystemen, det balanserade styrkortet och Hoshin Kanri, anses delvis besvara kritiken samt möjliggöra för företag att implementera sina strategier. Begreppet målkongruens beskrivs på olika sätt av olika författare, varför begreppet är intressant att undersöka samt hur målkongruens kan uppnås i företags planeringsprocesser.Syfte: Syftet med denna uppsats är att beskriva planeringsprocessen i målstyrningssystem samt att förklara hur målkongruens uppnås. Vidare är syftet att precisera begreppet målkongruens samt formulera en metod för att stärka målkongruens.Metod: För att uppnå uppsatsens syfte har två fallstudier gjorts med två företag som arbetat med att implementera och utveckla arbetet med ett balanserat styrkort och Hoshin Kanri. Tre intervjuer har genomförts på respektive företag med personer med god insyn i och erfarenhet av arbetet med målstyrningssystemen det balanserade styrkortet och Hoshin Kanri.Resultat: De båda målstyrningssystemen är mycket lika.

Micronic Laser Systems AB produces and develops machines for the photo mask production market. One of their products is the Omega machine which exposes photo masks using 5 laser beams simultaneously. It is important that the distance between the each laser beam, the x-separation, is the same. The x-separation is today measured by exposing a photo mask with a certain pattern and thereafter measured with a metrology system. This takes to much time and it is desired to find a faster method to measure the x-separation without loosing precision.The task for this master thesis is to improve an existing measurement method which uses a calibration mask.

The purpose of this thesis is to examine the performance of queries that are expanded by 1 inflections, 2 compound splitting and 3 inflections and compound splitting combined. For compound splitting, the morphological analyser SWETWOL was used. Queries were executed in the Query Performance Analyser, QPA, containing the InQuery system. Query terms were selected from 29 topics, all of whom containing at least one compound word. Both the queries and the documents were in Swedish.

In today´s forestry, assessments of needs for thinning are based on basal area measurements. This is an indirect measurement. The approach and the developed assessment tables are based on an assumed production forest, which implies that management proposals in stands that deviate from the basic model may be misleading. Since Walter Bitterlich in 1948 launched the idea of the relascope, several modifications have been developed for different purposes. In common is that all are based on a certain angle measurement principle.

The mining company LKAB extracts iron ore in three areas in the north of Sweden, Kiruna, Malmberget and Svappavaara. The iron ore is refined and in the pelletizing plants the material is rolled to finished pellet product. The different steps of pelletizing plants causes among other things emissions to the air. It occurs occasionally stops in the production and the emissions are vented via an emergency chimney without purification. The aim for this work is to look into how LKAB may improve their monitoring of air emissions and control of ambient air quality and the analysis methods which are suitable for measuring.

Private label introductions have been increasing in recent years. The main reason for this is that private labels increase the retailer's profits in the category. The purpose of this study is to examine how a private label introduction affects the category's performance. This study was conducted by studying the category's performance before and after the introduction, two categories are examined. Data have been collected at a Swedish retailer and consists of 38 stores, all located in Sweden and within the same store profile..

Earlier models that measured de facto harmonization of international accounting mainly used indices and other related statistical models. Those approaches do not account for the relative importance of individual balance sheet items or expense items being harmonized. This paper therefore proposes a different approach using Runsten?s (1998) permanent measurement bias model. That way it is possible to quantify the harmonization process by accounting for differences among companies.

This project has revolved around finding better ways of overseeing vibrations of the gearbox at a wind power station. The gearbox has been a huge problem at the stations located at Gässlingen and the sooner the warning of an incoming breakdown is at hand the more money you can save from preparations. The work has been carried out together with Askalon AB in cooperation with consults from ÅF. Askalon is a company with a department focused on overseeing vibrations and it is in collaboration with that department the work has been carried out. During this work, new positions for the sensors and new methods of gathering and analyzing data have been worked out. This was then implemented at a wind power station to be tried out on site.

The purpose of this thesis is to examine how key performance indicators are being used as performance management tools within the production industry. Specifically the purpose is to investigate how the KPI:s within the telecommunications industry drives reusability regarding production test systems. This thesis will also highlight today?s cost models and suggest improvements of the KPI and what new ones could be introduced. A case study at Ericsson AB has been performed.

During the last decades, brand equity has been a priority topic for both practitioners and academics. In accordance with the structural changes in the economic settings caused by the so-called "new economy", corporations being confronted with a shift on perceived business value structure from tangible assets to intangibles. On the other hand firms increasingly are adopting more responsible behaviour towards their societies. In this context, one critical question is to understand how corporate conduct may affect brand equity. The purpose of this study was to find how brand equity (BE) measurement methods embrace corporate responsibility (CR), based on a literature review.
