In today?s society computers are getting a much more important role. To get a computer to work as intended it has to be programmed. A computer program is written with programming languages. There is an abundance of programming languages available today and there are many differences and similarities between them.

It is a well-known fact that textiles and carpets have benign sound-absorbing properties. It is desirable to have quantified values of these properties ? especially for architects and interior designers. They often need to be able to giveaccount for the acoustic properties of their designs at a relatively early stage and sometimes have strict acoustic classifications imposed upon them by their contractor. A product with documented acoustic properties would aid when prescribing interior elements.The purpose of this thesis is to develop a wall-mounted panel in hand-tufted material ? aesthetically pleasing and versatile but also having documented and quantified acoustic properties.

This report describes the construction of a climate-cabinet for testing of HV-cards (High Voltage) produced at VG Scienta. The main part of the report describes all the different components of the cabinet. The most important parts are a PID regulator from Eurotherm model 2408, a solid state contactor (SSC), a thermocouple, a finned resistor from DBK and different fans. The report even includes the connection between components by cable wiring, isolation, grounding, fuses and shaping of metal goods.As the cabinet also communicates with a computer, the report includes the solution of the data communication using the software iTools from Eurotherm. The communication part includes information about a converter that converts EIA422 to USB.The cabinet was produced at a company, called VG Scienta, in Uppsala during the spring 2010.

The aim of this thesis was to investigate if the robotized welding method FSW (Friction Stir Welding) could be applied for joining a rotating structure in an aero engine at Volvo Aero Corporation. FSW is expected to introduce less defects than today?s welding methods and could therefore be suitable for critical aero components. The material is the nickel based alloy Inconel 718, however a material experimentation is outside the scope of this report.The main goal of this study is to verify if the ESAB ROSIO robot based FSW-system has a suitable work space to be able to weld the rotating structure, and if the welding tool has accessibility to the joints. The FSW-process needs a rigid fixture, and a number of fix-ture concepts are presented based on a proposed weld sequence.

This thesis presents a system which has been implemented to satisfy a need in theresearch on how speech planning interacts with syntactic and prosodic structure inspontaneous speech. The long-term purpose of the research is to provide models forautomatic parsing of spontaneous speech and for psycholinguistical modelling of speechproduction. Identification of inhalation pauses is an important step in the developmentof automatic methods for spontaneous speech parsing.Identification of inhalation pauses is considered to be a keyword-spotting speechrecognition problem. Hybrid HMM(Hidden Markov Models)/ANN(Artificial NeuralNetworks) approach is applied to this problem. Method gets 90,8% in Recall, 66,4% inPrecision and 76,7% in F-score.

Produktframtagningen av en moduluppbyggd destinationsskylt för bussar utfördes på Högskolan i Skövde i samarbete med företaget Mobitec AB som bland annat säljer de skyltar som används i stadsbussarna i London. Den destinationsskylt som togs fram var tänkt att fungera som ersättare för de tryckta dukskyltar som var befintliga i Londons stadsbussar och var därför tvungen att leva upp till deras krav på upplösning och läsbarhet. Detta skulle åstadkommas genom att bygga upp skylten med ett modulärt system av Super Fine Pitch LED Matriskort. Modulsystemet behövde klara viss påfrestning från vibrationer från bussen och tillåta enskilda moduler att lätt monteras och demonteras. För att ta fram ett fungerande system användes riktlinjer för DFA och DFD och användarbehov från montörer och reparatörer undersöktes. Under idégenereringen användes Set-based concurrent engineering för att inte felaktigt vidareutveckla ej fungerande koncept på bekostnad av eliminering av fungerande koncept. Tre resterande, likvärdiga koncept modellerades och testades för vibrationssimulationer i Creo Parametric 2.0.

This report summarizes a Bachelor Degree Project in Integrated Product Development, carried out during the fall 2007 till spring 2008 by three students at the Product Design Engineering Program at the University of Skövde. The project was performed in cooperation with Lundbergs Möbler AB in Tibro. Lundbergs wants to start selling furniture to the public eldercare. The purpose of this project was to adjust one of their chairs. The project layout was to first make a preliminary investigation where the market, competitors? assortment and the purchasing process are studied.

The purpose of this thesis is to examine and analyze how to improve the design of a Microsoft Surface SUR40 application. The application in focus was an interactive product browser developed by the company Spree, our external client. Spree is a multi-touch software provider, established in September 2010 and they expressed a need for suggestions for how to improve this application. Our work aimed at revealing how to make the application more suitable for several users and make it easier for them to interact simultaneously on the surface. From a qualitative standpoint we have examined how 17 users experienced the application.

Minimizing power consumption is a critical part of many embedded design projects. Thechallenge is to limit the power consumption of the system and at the same time providesatisfactory service to the user. With regards to microprocessors, the main way of limiting powerconsumption during program execution is to adjust the frequency and the voltage at which theprocessor operates.To enable the implementation of real-time scheduling with support for dynamic voltage andfrequency scaling, an exhaustive study of the Freescale i.MX31 embedded microprocessor isperformed. Specifically, the power consumption relationship to all relevant frequency andvoltage settings is investigated. In addition, to enable frequency and voltage scaling in a real-timeenvironment, a complete timing analysis of proposed voltage and frequency scaling methods isperformed and their suitability for use in real-time systems is evaluated.To integrate voltage and frequency scaling capability into OSE RTOS, a software module hasbeen developed for this operating system.

VD:n för spelindustrins intresseorganisation (Interactive Digital Software Association) förutspår i den årliga State of the Industry rapporten för åren 2000 ? 2001, att spelindustrin snart kan nå 70 procent av världens hushåll, vilket gör spelmaskinen, näst intill, lika vanlig som videon. I denna dag börjar många spelutbildningar växa fram i hela landet, så som i Karlshamn, Visby och Kramfors. Trots denna tillväxt finns det nästan ingen akademisk forskning i ämnet speldesign. Detta gör att hjulet i många fall tvingas återuppfinnas om och om igen.

Denna rapport behandlar ett examensarbete inom integrerad produktutveckling som utfördes av Andreas Carlsson och Marcus Ronnheim vid Designingenjörsprogrammet på Högskolan i Skövde vårterminen 2008. Examensarbetet var att utveckla Casall Sports Products viktskivor, viktlås samt viktställ för bodypumpviktskivor. Bakgrunden till uppdraget var att Casall tyckte att deras, redan nämnda produkter, var föråldrade och behövde ett nytt utseende samt att viktstället saknade vissa fördelaktiga funktioner. Rapporten beskriver hela produktutvecklingsfasen från förstudie till produktionsritningar.Under förstudien gjordes bl.a. en marknadsundersökning och användarintervjuer, detta resulterade i en kravspecifikation.

Lufttätheten hos en byggnad påverkar dess energiprestanda, luftkvalitet inomhus, ljudisolering och riskerna för fuktskador. Lufttäthet definieras i Sverige oftast utifrån klimatskalet, i enlighet med tidigare byggnadsregler och den svenska definitionen för passivhus. Däremot finns det idag inga specificerade myndighetskrav på lufttäthet i Sverige. I examensarbetet undersöks lägenheterna i ett flerbostadshus i Malmö. Förutom lufttäthetsprovningar enligt SS-EN 13829 gjordes en mottrycksmätning för att bestämma läckaget mellan två lägenheter.

This thesis examines a possible control strategy to minimize flow fluctuations in Uppsala?s district heating system. High variations in flow rate may lead to complications caused by hydraulic constraints in the district heating system. These complications, such as inadequate pressure and temperature levels, increase the risk of heat delivery failures. It is therefore important to avoid such situations both for the producer and for the customers.Typically, the forward temperature is controlled by using a rough correlation with respect to the outdoor temperature.

Internet and information technology today has a rather obvious role in the activities of companies and organizations. All cash transactions within and between companies is digitized, communication within the company is done via e-mail, sales and marketing is done largely with marketing and ads on the Internet. This has resulted in economic benefits for companies and organizations, and facilitated the work for them. However, this has also led to new threats have emerged. Companies and organizations is well aware that there are numerous threats that comes with using the Internet and Information Technologies but exactly what those threats are for a mid-sized company in Sweden is not clarified anywhere.
