The development in electronics increases the demand for good design methods and design tools in the field of electrical engeneering. To improve their design methods Ericsson Microwave Systems AB is interested in using computer tools to create a link between the specification and the implementation of a digital system in a FPGA. Xilinx System Generator for DSP is a tool for implementing a model of a digital signalprocessing algorithm in a Xilinx FPGA. To evaluate Xilinx System Generator two testcases has been designed. The testcases are selected to represent the FPGA designs made at Ericsson Microwave Systems.

These studies are done in behalf of Saab AB AVITRONICS in Järfälla in the form of a thesis atthe Royal Institute of Technology in Stockholm.The task was to examine the parameters that plays a role in the construction of modern radomesoperating in broadband applications.This was interesting for Saab to get an indication of which way they should go at the newdevelopment of radomes for the next generation of equipment for electronic warfare.After a thorough analysis of the influencing parameters, a optimization application was made toget a automated way to get a radome design by specifying data on the radome size, airloads,materials, etc.This is to minimise the time of the laborious work that radome development.inply.This was solved by letting ANSYS calculate the strength of the radome structure and MATLABcalculate electromagnetic data and cost models of different sizes and materials.All these parameters woven together with the optimization tool modeFrontier picks data from therespective program and perform an optimization algorithm and then iterate a step and sends thisdata to calculation programs for the new input data. In the end, we have received a convergedpoint with our optimal solution.For the presumptions and limitations for which applied for this thesis, the result was prettyintuitive. That is to say that the smaller radome - the less materal is needed and lowermanufacturing costs results in the cheapest solution possible. The reality is not so simple. Whereyou have to take more of the electrical details such as the effect on the transmitter as a majorfactor..

The main purpose of this thesis has been to identify and discuss problems connected with the preservation of newspapers in Sweden. Another purpose was to see if the preservation of newspapers has been influenced by the fact that preservation studies in general concerns printed monographs and digital materials. This qualitative study is partly based upon interviews with four librarians experienced in working with newspapers and preservation. The thesis deals with cultural heritage in general and on a more specific level with newspapers where the following questions are dealt with: Why preserve? Who preserves? How to preserve? and What is preserved? Strategies used for preserving newspapers such as paper, microfilming and digitization are described as well as legal deposit, the Swedish microfilming programme and TIDEN, a digitization project of newspapers.

Marinediesel Sweden AB i Ängelholm tillverkar och utvecklar båtmotorer och motorbåtsdrev. Jaggjorde mitt exobb på avdelningen MD Engineering som huvudsakligen utvecklar marina drivlinor.Marinediesel Sweden AB var i behov av ett styrprogram till den testbänk de byggt för att kunna testasina motorbåtsdrev. Denna rapport beskriver arbetet jag utfört för att färdigställa och optimera ettstyrprogram till en testrigg för marina drivlinor. I rapporten tar jag upp drevbänkens uppbyggnad, dessfunktion samt de problem jag stött på på vägen.

The thesis has been written as a part of the Bachelor degree in Industrial engineering and management at the School of Engineering in Jönköping. The work is focused on the part of Husqvarna AB?s supply chain that is associated with the lorry transports to Italy. Husqvarna AB has approximately ten Italian customers, whose delivery patterns have been studied from January 2007 to July 2008. Some of the customers have a low delivery frequency and small amounts of goods that they therefore have not been fully analyzed in this report.

Syftet med uppsatsen är att undersöka hur elever klarar att lösa problem som inte kan lösas rutinmässigt och där de inte har tillgång till hjälpmedel. Dessutom vill jag undersöka hur elevens betyg och antal matematikkurser eleven har läst påverkar resultatet. För att få svar på detta lät jag eleverna i två klasser ifrån det naturvetenskapliga programmet, en ifrån årskurs ett och en ifrån årskurs tre, svara på ett frågeformulär bestående av uppgifter som inte går att lösa rutinmässigt.Resultatet visar på att eleverna i årskurs tre klarade testet poängmässigt klart bättre än vad eleverna i årskurs ett gjorde och i båda klasserna visade elever med höga betyg ett bättre resultat än elever med lägre betyg. Det mest överraskande var att båda klasserna trots höga matematikbetyg visade på vissa brister i taluppfattning..

The electric car has existed for over a century and producers has tried to commercialize it earlier but has not succeeded. In recent years, however, a change occurred that may be significant for the electric car and it is now to commercialize in the market of passenger cars. The technology has in recent years elaborated as more car manufacturers have started to invest in development in the subject field. This thesis aims to compile an action plan for the development of charging infrastructure for electric vehicles in Uppsalahem ABs residential areas. It is based on a survey of different residential areas and a survey of charging infrastructure.

This paper examines the power producing dams along the Ume-river as an integral part of and a result from the urbanization process in Sweden during industrial capitalism. The aim of the paper is to contribute to the knowledge of the urbanization process in Sweden in general and of its traces along the Ume river in the county of Västerbotten in particular. The paper applies the theory of concentrated urbanization and extended urbanization put forward by Neil Brenner and Christian Schmid (2015) and argues that the building of power producing dams along the Ume-river is part of an extended urbanization process. This becomes particularly evident when examining the vast physical structures that is the dams, situated in an otherwise remote and sparsely populated area. These vast physical structures are also very well connected to a nation wide electric grid that has connections to bordering countries as well.

Den 30:e september 1998 mottog Konkurrensverket ett klagomål ifrån Braathens Sverige AB, enligt vilket SAS (Scandinavian Airline System) anklagades för att på olika samverkans förfarande missbrukat sin dominerande ställning på den svenska inrikesflygmarknaden. Några veckor efter klagomålet från Braathens beslutade Konkurrensverket att avsluta klagomålsärendet och istället på eget initiativ pröva SAS förfarande. Den 12:e november 1999 beslutade Konkurrensverket att SAS inte fick tillämpa sitt Eurobonussystem på inrikeslinjerna där det fanns andra konkurrenter. I praktiken rörde det sig om linjerna Stockholm-Göteborg, Stockholm-Malmö samt Stockholm Sundsvall..

The competitive nature of the automotive industry has always implied a necessity to improve product development concerning time-to-market, cost and product quality. As capacity of computer-aided engineering (CAE) tools has evolved, so has the strive for simulation-driven design. Virtual durability testing using full vehicle models is one of many challenges posed in front of vehicle manufacturers when computer simulations are given a key role in product development.This thesis has been initiated as a preliminary step towards implementing dynamic virtual durability testing in the development of buses and coaches at Scania. The objective has been to assess the predictability of a full vehicle coach model and to what level of precision structural loads can be predicted. Previously performed proving ground testing of a Scania Touring coach has been the basis for the modelling and simulations in this thesis.A virtual model of the Scania Touring coach has been created in multi-body simulation software package MSC.Adams.
