Datorstödd implementering med hjälp av Xilinx System Generator

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.

Upplyst trapphus

The purpose of this thesis was to increase the understanding and discuss safety aspects in two stairwells on Nyforsgatan in Eskilstuna, where the buildings were built during the years 1965-1975. I have presented a proposal for improvement through lighting. I have through different methods, such as surveys, interviews, literature studies and observations, come to a conclusion: that there are opportunities for improvement through better lighting that allows orientation in space and creates a nice atmosphere which will remove the feeling of not being safe, e.g. dark corners and shadows. It has been an exciting process to gather enough of facts to rely on and to develop the lighting design for the environments.

Samverkan mellan geotekniker och konstruktörer

Föreliggande studie omfattar sättningsberäkningar med den senaste kommersiella versionen av datorprogrammet FEM-Design 12, utvecklat i samverkan mellan konstruktörer och geotekniker. Programmet är en uppföljare till den tidigare versionen FEM-Design 11 och även en förbättring av den betaversion 12, som fanns tillgänglig och under utveckling fram tills att den första kommersiella versionen av FEM-Design 12 lanserades under hösten 2013. Tidigare studier har gjorts av en Betaversion 12 i form av ett examensarbete, där jorden modellerades med volymelement, enligt kontinuumsmekanik. Resultaten i studien påvisade en stor procentuell sättningsdifferens (22 %) jämfört med sättningsberäkningar i det geotekniska programmet PLAXIS. Denna procentuella skillnad kan antingen bero på att själva byggnaden inte kan modelleras i PLAXIS och därmed inte kunde beaktas i beräkningarna, eller att det fanns brister i betaversionen FEM-Design 12, vilka gjorde att resultaten som uppvisades inte var rättvisande. I denna naturliga fortsättning har nya beräkningar gjorts med hjälp av den senaste kommersiella versionen av FEM-Design 12 för att validera sättningarna i en ny pilotstudie och undersöka om rimliga resultat erhålls. Som en del av denna jämförelse och värdering har även sättningsberäkningar för hand utförts. Interaktionen mellan FEM-Design och användarna har granskats för att se hur brukarna upplever den nya versionen samt om programmet uppfyller de mål som formulerades i samband med utvecklingsarbetet. Tre olika projekt har modellerats i FEM-Design 12 där jorden beskrivs med finita element (volymelement)..

Serveringskärl för restaurang

The water company MittSverige Vatten (?MidSweden Water?) located in the Medelpad, Sweden was in need of a moreexclusive water carafe for restaurants and conference in the region. Current design solution was not able to cope with thedemand of a more exclusive setting and was not promoting the company in a good way. In the beginning of the projectit became clear thru an intense interview period that there was at least three directions for design solutions the companycould go for.? A carafe (exclusive settings)? A pitcher (conference and lunch servings)? A water dispenser type (serving of larger amounts of water during a certain brief periods of time.)It was decided to go for the exclusive one.Small pieces of rock from the last ice age turned out to be a vital component of the new design concept for the company..

This project was conducted during the spring semester 2013 at mechanical engineering program at University Halmstad. The project was conducted in collaboration with MPQ Consulting in Halmstad. MPQ Consulting is a newly established company looking to take step into the product development world. The company has already had ideas and existing products. One of the ideas is to construct and design a form of beach games whose rules are based on the volleyball rules.

Konstruktion av beslag med dörrfunktion till spridarlucka

This thesis was performed at Zetterbergs Industri AB. Zetterbergs is designing, building and mounts body systems for trucks, including dumpers and tippers. The assignment for the thesis was to design a door hinge for a spreader gate. The spreader gate is the top of the two tailgates on a dumper or tipper and opens back and outwards when tipping the cargo. The spreader gate controls the mass flow of the material being tipped.

BIM för landskapsarkitekter : virtuell design och kommunikation

The purpose of this thesis is to describe what Building Information Modeling, BIM, could mean for landscape architects, and also hopefully to make sense of the possibilities and problems of the system. BIM is about virtual design and is based on all consultancy groups in the design team modeling in 3D. Intelligent objects and metadata, such as price and material, are used. The project group has a common interchange format for simple sharing of information. To get an idea of how the situation with BIM for landscape architects looks like today, I collected information mostly through interviews.

Mätning av Tidens Inverkan på Användarupplevelsen : En Fallstudie

Det finns i dagsläget få tids- och kostnadseffektiva metoder och tekniker för att mäta och utvärdera användarupplevelse över tid. Detta trots att tidsaspekten av användarupplevelsen under de senaste åren har uppmärksammats som en viktig komponent av användarupplevelsen inom människa-dator-interaktionsforskning. UX Curve och iScale är två metoder framtagna för att mäta förändringar i användarupplevelse över tid med hjälp av retrospektion och skapande av grafer över utvecklingen av användarupplevelsens olika dimensioner.Mot bakgrund av dessa metoder togs ett webbaserat utvärderingsverktyg fram med målet att undersöka verktygets förmåga att mäta förändringar i användarupplevelse under en utvärderingsperiod. Verktyget testades på 9 deltagare i en utvärdering av en mailklient under två veckors tid.Resultatet indikerar att utvärderingsverktygets dimensioner samlar upplevelser av relevans för de dimensioner som undersökts men visar också på att ytterligare testning och validering av metod och verktyg behövs för att fastställa att mätningarna är reliabla och att det som mäts är vad som avses mätas..

En jämförelse mellan fyra olika energisystemlösningar : För ett hus byggt efter passivhusstandard i Karlstad

AbstractWork to develop the Eurocodes started in 1975 by the European Commission adopted a program to eliminate trade barriers within the construction area. The goal was to create common European design standards that would replace the member countries' own rules. Eurocodes will replace The National Board of Housing Building and Planning, National Rail, The National Road Administration and other agencies' calculation rules for the buildings structures. The transition to the use of Eurocodes looks like this:Eurocodes set to Swedish standards  between 2002 ? 2007They can be used parallel with national standards 2006 - 2009 The total transition is at the end of 2010/2011.Right now is going on a lot of work for replacement of the existing standards to Eurocodes.  The transition to the new calculations` standards, many construction companies and consulting firms facing a big changes and competitions.

Att möta vampyren : Hur kan Twilight behandlas i skolan?

This essay discusses how popular literature in general and Stephanie Meyer?s Twilight-series in particular can be useful in the classroom, despite, or rather, thanks to, its inherent problems concerning gender roles, relationships and the power systems within them. The essay takes a reader and teacher centered approach in describing both the problems of Twilight and the ways these problems can be worked with in the context of the school subject Swedish in upper secondary school. It makes an inventory of Twilight?s problematic aspects, and attempts to use them in conjunction with the governing documents of the Swedish school system.

Electronic Journals, Just in Case, Just in Time, Just for You ? användning av elektroniska tidskrifter vid Chalmers tekniska högskola

This user study was carried out at the library at Chalmers University of Technology in Gothenburg in the spring of 1999. Chalmers wanted to investigate how much their employees use electronic journals. To facilitate decision-making and be cost effective, the library needed to know about their customers' opinions. The main purpose was to investigate the usage of electronic journals, how the library's choice of these journals affects the frequency of use and what the attitudes towards them are. A questionnaire was sent out to 2 400 employees; 477 replies were received.

Optimerad bildsökning ? Bör vissa egenskaper prioriteras vid sökning efter en viss kategori av bilder?

As the information society becomes increasingly flooded with digital images, the need for efficient image retrieval systems increases as well. To handle the vast amounts of data involved, the indexing process needs to be run automatically, using content-based descriptors extracted directly from the digital image, such as colour composition, shape and texture features. These content-based image retrieval systems are often slow and cumbersome, and can appear confusing to an ordinary user who does not understand the underlying mechanisms. One step towards more efficient and user-friendly retrieval systems might be to adjust the weight placed on various descriptors depending on which image category is being searched for. The results of this thesis show that certain categories of digital images would benefit from having extra weight assigned to colour, texture or shape features when searching for images of that category..

Användarcentrerad design och agila metoder : Integrering av prototyping och Extreme Programming

 Agila metoder är en relativt ny ansats inom programvaruutvecklingsområdet och ses som en reaktion mot plandrivna metoder som har svårt att hantera oförutsägbara och skiftande krav. Agila metoder förespråkar nära och frekvent kundkommunikation och iterativt arbete för att ständigt kunna skapa, prioritera och verifiera krav. Dock uppmärksammar inte agila metoder aspekter som berör programvarans användbarhet. Syftet med rapporten är därför att integrera användarcentrerad design för att öka fokus mot programvarans användbarhet hos agila metoder. Användarcentrerad design är en process som fokuserar på användbarhet genom att användarna är en central aspekt i utvecklingsprocessen.

Akka. Ett skrivbord för hemmet anpassat för rullstolsburna.

A woman is dying of cancer, she refuses to use her walking aid. Because she is embarrassed. This means she can?t leave her house, and her last days become very limited.Why do we act like this?Can the view we have of products adapted for disabled be changed by working with colour, texture, form and materials?There are many products adapted for disabled, the products often have a good function and well developed ergonomic aspects but the visual aspect leaves a lot to wish for. There is neither effort nor money put in to the exterior design of most of these products.A lot of the solutions that are invented for adapted products can be used in design of ?regular? products.Why should we then divide products in to adapted and non-adapted.
