För att en kvalitativ och driftsäker kraftomvandling från vind till elkraft skall erhållas ställs krav på en mängd olika faktorer. Klimatologiska och tekniska faktorer kräver korrekt dimensionering och anpassning av omvandlingstekniken för att största möjliga energimängd skall kunna omvandlas på ett driftsäkert och energieffektivt vis som vindkraftsägare, nätägare kräver. Vinden är som bekant en oberäknelig kraftkälla. Variationerna i styrka och tid kan innebära en hel del driftoptimeringsproblematik med efterverkningar för vindkraftsverket, nätet och belastningen. Konsekvenserna kan bero på vilken typ av teknik som är installerad i de olika delarna av energisystemet och i områdets elnät.

Under vårterminen 2011 har jag studerat hur ett verktyg påverkar en arbetsprocess. Från en idé har ett projekt vuxit fram och två ljudbanker för musikproduktion har producerats, detta har gjorts möjligt genom att jag har studerat digital ljudproduktion på Blekinge Tekniska Högskola, där intresset för det som blivit mitt kandidatarbete, har väckts till liv. Mitt kandidatarbete har resulterat i två ljudbanker, den ena banken har fokus på digitala trummor medan den andra har fokus på synthar. Slutreflektionen berättar hur denna process har gått tillväga, och hur resultatet blev. Jag för fram för- och nackdelar av arbete i Dune, hämtar fakta från kända producenter inom elektronisk musik och bedömer det resultat jag har får. På både gott och ont har dessa två ljudbanker blivit två produkter.

In this thesis the subject innovation and the change of meaning is in focus. The purpose of the study is to present a new dimension of innovation as a change of meaning together with the cases we?ve studied. It is discussed throughout the article if theories of perception and association can affect the organization and its ability to create meaning-changing innovations. The industrial robotics is a market in need of, perhaps, if not other markets but of finding new ground that results in the change of meaning.

The use of CAD, within the building industry came strongly, during the 1980?s and the 1990?s. The development has since then rapidly progressed and the using of 3D-models has in addition increased. We are now at the edge of next step of evolution. BIM, Building Information Model(ing), is here.

In the thesis we have shown that it is possible with current technology, to buildneighborhoods that are largely self-sufficient. We have obtained some information aboutongoing work in the field of energy efficient buildings and active house which we have usedto develop a model. The feasibility study for Ranagård we have e.g been forced tofollow laws on groundwater covered, resulting in the construction of basements for singlefamilyhome is not possible. The model that we have built up overtime has been the central part of the work. The model illustrates very well what an activehouse neighborhood means and potential of such an area.

To curb greenhouse gases and mitigate climate change is one of the biggest challenges human society face today. Carbon dioxide (CO2) has accumulated rapidly in the atmosphere as a consequence of burning of fossil fuels and deforestation. The aim of this study is to explore two methods to store carbon dioxide in geological formations and biological sinks. The aim is also to discuss the two mitigation options from a sustainable perspective and whether it can lead to a better environment and benefits for local and global societies. The research questions are: Which method to store carbon dioxide, geological or biological, is the most effective? Which method to store carbon dioxide, geological or biological, has the greatest potential to promote sustainable development for local communities?The method used is a comparative case study and presents four case studies that explore the potential for CO2 storage offshore in Norway and Brazil; and in tropical forests in Mexico and Brazil.

The Division of Language and Communication at Chalmers uses a web-based language tool, named EngOnline, to teach English grammar. The language tool suffers from some shortcomings. These include stability problems and an outdated interface but, above all, there is no documentation. Because of the lack of documentation and EngOnline?s need of maintenance, the Division of Language and Communication has decided to replace the language tool with a new and well documented one.The new language tool was developed using an agile work process; detailed documentation was replaced with more efficient communication.

This thesis is the final part of bachelors program of Nuclear Engineering at UppsalaUniversity (program code KKI1). The work has been carried out in cooperation withForsmark Kraftgrupp AB.

Inspections, fuel replacement and repairs areincluded in the annual overhaul.

The security solutions used in wireless home networks are examined in this report. Thegrowing number of wireless units have increased the need for reliable security solutions.This report aims to enlighten the reader about the fundamental technology used inwireless security solutions and inform about the existing flaws. A recommendationabout how to achieve a high level of security in the home network is also given to thereader.Several flaws in the security solutions in use have been reported. Of these the mostsevere has been examined in a test network using highly accessible tools to get aperception of how vulnerable the user is.The tests showed that several attacks were efficient and easily carried out. We have alsoseen that several of the home networks in our sample are susceptible to these attacks.Our survey revealed that the Internet service provider's technical support in many caseslacked the knowledge necessary to inform the user about reliable security solutions..

People with disabilities constitute a big group of Internet users. Due to great advances in adaptive technology for people with disabilities more and more disabled will have access to Internet. For that reason it is extremely important for a web developer to be aware of different disabilities that complicate or prevent using Internet, different adaptive technologies that facilitate using Internet and different methods, both in design and programming, that make Internet accessible for people with disabilities.In this report we have dealt with three problems:? Which types of disabilities that complicate or prevent using Internet?? Which types of adaptive technologies are available concerning using Internet?? How can a web developer or programmer increase the accessibility to Internet for people with disabilities?To investigate how disabled people use adaptive technologies and which difficulties they experience when using Internet we have interviewed people with various types of disabilities..

 Autonomous cars or robot cars havebeen on the agenda ever sinceHollywood started with their Sci-Figenre, maybe even before that. A lotof things have happened since then andnow the self-driving vehicle is notfar away. In this project, theAutonomous car with microcontrollerand ultrasonic sensors, we are lookingat a way of making a small, regular RCcar autonomous with relatively simplemeans and investigate how the bigcompanies does it to learn more aboutthe development of the autonomous carsand their technology.We used an Arduino Uno R3 supplementedwith an Arduino Motor Shield R3 as ourmicrocontroller board and three HCSR04ultrasonic sensors. By removingalmost all of the old parts of the RCcar,except the two DC motors, andreplacing them with these new parts wemanaged to make a vehicle that drovearound in a room without crashing intoanything. We could have used entirelydifferent sensors, or supplemented theexisting setup with other sensors tomake it even more accurate andobstacle avoiding.

Abstract In this report I describe the Health Care Advice Bureau?s (sjukvårdsrådgivningen) historical background, proposals for its development according to a committee from the Blekinge County Council (Landstinget Blekinge), the Health Care Advice Bureau?s cooperation with different external operators e.g. the SOS and the Care Centers [Vårdcentraler]. I account for how I, in the same county council, aided by ethnographical methods observed or investigated the following: The nurses? interaction with the patients, the nurses? interaction among themselves, the nurses? participation in the development of the system and also the computer based system?s technical qualifications.

Syftet med detta examensarbete är att vidareutveckla glasfiberbalkar så de kan användas som mellanbjälklag i småhus. Förebilden var ett ?Delta Deck? som utvecklats av Altakor Group och används i brokonstruktioner. Denna profil har vi sedan modifierat och optimerat för bruk i småhus. Den största skillnaden är att vi valt att inte använda den så kallade ?snap-fit?-tekniken.

Syftet med den här rapporten är att utveckla och testa en hållbar, säker, tyst och kostnadseffektiv bromslösning som X2 Technology AB kan implementera i sina lyftpelare.Lyftpelaren har idag dubbla bromslösning medför en merkostnad som är onödigt kostsam och därigenom ofördelaktig ur konkurrens och vinstperspektiv.De dubbla bromsarna tillför inget mervärde för kunden, därför är det viktigt att minimera kostnaderna som detta innefattar.I denna rapport har olika friktionsmaterial testats med hänseende till missljud, lasthållning och mikroglidning.Det resultat som uppnåddes var ett par alternativa friktionsmaterial och annorlunda yta på bromsen som visade sig fungera väl ihop med dessa material. Även ett ändringsförslag till en alternativ broms som tidigare testats togs fram. Detta nya utförande har inte hunnits testats ännu..
