Fler människor börjar använda olika mobila operativsystem i mobiltelefonen samt appar som enbart fungerar på plattformen. Det leder till att app-leverantörer måste utveckla varje app till varje specifik plattform vilket är dyrt. De vanligaste operativsystemen som används idag är Android samt IOS men hösten 2012 släpptes Windows Phone 8 vilket innebär ytterligare en plattform att ta hänsyn till. I sammarbete med företaget Sogeti Jönköping fokuserar studien på att hitta en metod som gör det möjligt att migrera appar mellan plattformar och till Windows Phone 8. Studien innefattar också att identifiera för och nackdelar med olika app-typer genom en litteraturstudie och intervjuer samt att testa om migrationsmetoderna fungerar praktisk genom en implementation.Resultatet har påvisat att det finns två stycken olika metoder för migration vilket är PhoneGap och Xamarin.

The determination of the optical properties of biological tissue is an important issue in laser medicine. The optical properties define the tissue´s absorption and scattering behaviour, and can be expressed by quantities such as the albedo, the optical thickness and the anisotropy coefficient. During this project, a measurement system for the determination of the optical properties was built up. The system consists of a double integrating sphere set-up to perform the necessary reflection and transmission measurements, and a computer algorithm to calculate the optical properties from the measured data. This algorithm is called Inverse Adding Doubling method, and is based on a one-dimensional transport model.

Lime Hempcrete consists of lime, water and hemp and creates an insulating, sound-absorbing, lightweight and environmentally friendly material that can be used in wall, roof and floor structures (Bevan & Woolley 2008). This construction method is not yet developed in Sweden as there has been a ban on the cultivation of the hemp plant. This ban on the cultivation of hemp was removed in 2003, when the material got a boost. You can use it in many different ways and not just in the construction industry (Ahlsten, 2010).In this study we have investigated the possibility to produce prefabricated wall elements of LHC. We have also studied its mechanical properties and dehydration time.

Ericsson develops a new stripline directional coupler. Its design is described in appendix B and differs from the directional couplers Ericsson uses in current products. The new directional coupler will be used for transmission power measurement in future UMTS 3G base stations.The most important parts of directional coupler theory are presented. It is necessary to study this theory to understand how the coupler works and how it should be designed to get good performance.Optimal directional coupler termination component values to get high directivity and broad directivity bandwidth have been investigated.The trim screws trim ranges have been studied.A simple analysis of serial production performance when termination component tolerances are taken into consideration has been done.The resistance components reactive (inductive/capacitive) characteristics at 2.14 GHz have been analyzed.The directivity performance limitations of the directional coupler, when Ericsson?s band pass filter is connected, are investigated.Design changes leading to better performance are proposed.

Nanotechnology, one of the most interesting sciences today will no doubt have an enourmous impact on tomorrow's society and industry. One of the most interesting nanomaterial that has been discovered is the semiconductor quantum dot (QD). This material shows interesting novel properties such as a size-dependent band gap, which is an effect caused by the quantum confinement effect in all three dimensions. Due to this phenomenon the absorption spectrum can be tuned to the desired value by adjusting the size of the QD.This thesis aims to investigate how the solvent ratio of H2O/Ethanol affects the optical and structural properties of copper sulfide QDs manufactured in a chemical synthesis way using modern microwave heating. The process of manufacturing QDs using chemical synthesis often involve a capping-agent to prevent the QDs from agglomerate into bigger structures.

There are different ways of developing a second language. The purpose of this qualitative study is to investigate whether and possibly how music, focused on singing, can improve the development of Swedish as a second language. Through interviews with three vocal teachers, from three different schools in Sweden, and observations of one of the vocal teachers, information about how they work and think about the subject has been collected. The vocal teachers teach groups of second language learners by singing songs made especially for second language learning. The vocal teachers consider singing beneficial in the development of the pronunciation and improvement of the prosody, which affects the students? capacity to sound like a native Swedish speaker.

I detta arbete har vi försökt skapa en metod som skulle kunna hjälpa ljuddesigners inomindieföretag att med begränsade resurser komma fram till en kvalitativ ljuddesign genom attanvända en form av återvinning. Syftet med vår metod, som vi kallar för pantametoden, går utpå att återvinna ljudmaterial med hjälp av effekter för att skapa nya och kreativa ljud som går attanvända i en produktion. Vi kommer att gå igenom de nödvändigaste delarna för att visa hur vitillämpat vår metod, exempelvis vilka verktyg som finns och hur de kan användas för att uppnådet resultat som eftersträvas. Metoden har testats på två stycken spel som vi har varit med ochutvecklat, och där vi har bidragit med ljuddesignen med hjälp av vår metod. Vi kommer attpresentera vilket resultat vi har uppnått, och vilka problem som har uppstått..

This thesis treats the subject of a complete steady state and dynamic model of the VSC-HVDC covering both the AC and DC system-side of the converter. The topology of the model is recreated after the scheduled transmission line in the south of Sweden, called SydVa?stla?nken. The topology covers both a simple two terminal connection as well as a multi-terminal one. This model is to be implemented in the power system simulation program ARISTO.

Background: The business market today is characterized by tough competition amongst the competitors to capture consumers? interest and money. One marketing tool companies can use to achieve this is the company?s image. The customer buys not only a product, but also the image that the company or the product is associated with.

The aim of this master thesis was to find and grade suitable sites for wind turbines in the rural district of Lerum at the reguest of Göteborg Energi. The rural district of Lerum consists of very complicated terrain which was the reason why we picked Lerum.The assignment was achieved by using the software program ArcGIS and its attendant tools. In step 1 an overall analysis was made in order to sort out the least suitable sites. Step 2 consisted of a 3D analysis in ArcScene together with a more precise analysis in ArcMap. As result we found two interesting sites, which met our demands and specific constraints.

Den här uppsatsen behandlar en studie i hur man arrangerar för blåsinstrument inom popmusik. Arbetet avser arrangemang till 3 låtar för blåsmusiker och kompmusiker samt inspelning av arrangemangen i studio. Arbetet har genomförts med musiker från Piteå musikhögskola samt genom intervjuer med svenska professionellt verksamma arrangörer.Arrangemangen och inspelningarna genomfördes på Musikhögskolan I Piteå under vintern 2013.Det jag har kommit fram till i detta arbete är att det viktigaste när man skriver blåsarrangemang är hur man komponerar arrangemangen. När man instrumenterar arrangemanget är det viktigt att ta hänsyn till vilken genre man arrangerar för samt vilken nivå musikerna som ska spela arrangemanget är på. Av dom inspelningstekniker som finns föredrar jag att hela blåssektionen spelar in tillsammans.

Rotavirus and coronavirus are the two most common viral causes of neonatal calf diarrhea and their presence causes a lot of economic damage to the farmers as well as suffering to the animal. By getting better knowledge about the viruses we may help in tracing transmission and in producing new vaccines. This paper served to study the molecular epidemiology of rotavirus and coronavirus in fecal samples collected from two different farms in the state of São Paulo, Brazil. These samples have been studied with focus on the gene VP4, VP7, NSP4 in rotavirus and the gene S1 in coronavirus. From the first farm the screening PCR showed that 12/48 samples were positive for rotavirus and 4/48 positive for coronavirus.

Embedded Systems Lab at Umeå University is currently part of a research project with the purpose to examine the behavior of dairy cows inside a barn. Each cow needs to be tracked with a precision of 50 cm, and since GPS-technique has poor functionality at indoor environments, an indoor positioning system needs to be developed.Embedded Systems Lab has already developed an indoor positioning system using IR-light and radio, but since this system demands extensive infrastructure and is rather expensive, an alternate positioning system using ultrasonic pulses and radio is being examined.In this report the range, beam angle and current consumption of ultrasonic transmitters- and receivers are investigated. Three different driver stages for the transmitter is tested, and two amplifier solutions for the receiver. The report also describes how the length of the transmitted ultrasonic pulse affects the received signal, accessibility of a ?shadowed? signal, and the effect of different sound frequency..

Abstract In high voltage substations there is an increasing demand for computerized equipment, and automation of operation and supervision. The future primary equipment will provide the possibility to collect more information and to provide better control for improved effectiveness. Since ABB has got a large customer target, each product must be custom made to fulfil the customers (often from different countries) demands. Later these products will be configured by engineers who may not be familiar with the tools used at ABB. This is a very expensive and time consuming.
