Trådlös överföring av styrsignaler
Anledningarna till att använda sig av en trådlös signalöverföring i en industri kan vara många, oftast handlar det om ställen där det är svårt eller omöjligt att ha en trådad förbindelse. I det här fallet är det en sedimenteringsbassäng där man tar hand om processvatten från industrin. Bassängen är utformad som en cylinder där vattnet rinner genom olika avdelningar för att minska innehållet av sediment. I bassängen cirkulerar en plattform med diverse omrörare och skrapor på. Eftersom denna del går runt hela tiden är det svårt att ha en fast förbindelse till de drifter som finns.
Skattning av fordonsmassa med driftstatistik
In the automatic manual Transmission system, Opticruise, the choice of gear is based on several parameters such as road incline, driving resistance and vehicle mass. Many different mass estimations are made during driving. A final vehicle mass is then used to determine the current gear. Construction vehicles are often not equipped with air suspension and can therefore not estimate the vehicle mass when standing still. If that sort of vehicle is reloaded while standing still an incorrect mass estimation will be used and as an effect of that also a wrong gear.
Utveckling av transmission ochtestrigg till ett vågkraftverk
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.
Double integrating spheres: A method for assessment of optical properties of biological tissues
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.
Analys och förbättringsförslag för riktkopplardesign
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.
Optical and Structural Properties of CuxS Quantum Dots Concerning H2O/Ethanol Solvent Ratio
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.
Dynamisk modellering av VSC-HVDC : En statisk och dynamisk modelldesign o?ver VSC-HVDC fo?r implementering i ARISTO
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.
Image follows structure
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.
Diagnosis and molecular epidemiology of bovine rotavirus and coronarvirus in Brazil
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.
Design och implementation av konfigurationsverktyg för funktionsblock
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.
Självbiografins position på det litterära fältet
The purpose of this paper is to study the image of Strindberg that is conveyed in four different textbooks for the upper secondary school. How do the teaching authors choose to portray Strindberg? Do they focus on any one particular aspect of his writing? Adjacent to this a subsidiary aim is to see if teaching authors highlight the fictional nature of Strindberg?s works or choose to encourage a biographical interpretation. The work consists of a study of four literary history textbooks in the subject of Swedish for the upper secondary school, from 2000 to 2012. In the selected material the sections focusing on Strindberg and his writings are closely read and critically analysed.
Etiologi för sporadisk hepatit E i industriländer
Det finns många olika typer av bromerade flamskyddsmedel. De är alla stabila i miljön men graden av toxicitet och bioackumulering varierar. Att bromerade flamskyddsmedel är
endokrinstörande är känt men min hypotes är att de även är neurotoxiska och att de kan orsaka neurologiska störningar hos människa.
Människor exponeras för bromerade flamskyddsmedel via damm och föda. Barn och foster som är känsligare än vuxna kan även exponeras via modersmjölk respektive placenta. Barn
har högre serumkoncentrationer av bromerade flamskyddsmedel än vuxna.

Balansering av vindkraft och vattenkraft i norra Sverige
This master thesis was initiated with the aim to answer at what level of installed capacity of wind power in the northern parts of Sweden it would be beneficial to improve the Transmission capacity from the northern Sweden. During the process of this work the aim has changed to try and create a model that can be used to analyze how well the hydro power installed in the northern Sweden can even out the quick changes in wind power production.To create a good model of all hydro power in northern Sweden is a very large job, unfortunately too large for a master thesis. This report therefore ends with an extensive analysis of the simplifications that have been made and their effects as well as a list of the future work that has to be done.The model that has been created have shown to be effective and produce good results. The conclusions that can be made is that the northern Swedish hydro power have very good possibilities to balance the wind power production. Only a few cases where water have been spilled even though there has been some free capacity has been discovered.
