Voltage sag indices are a way of quantifying the performance of the power supply, as far as voltage sags are concerned. Indices can be defined for individual events, for individual sites, and for a whole system. A standard method for single-event methods is part of IEC standard 61000-4-30.This thesis emphasizes the importance of voltage sag indices and different methods for calculating three-phase voltage sag characteristics. Three-phase events measured in a medium network voltage over period of one month were analyzed, results examined and statistically evaluated. An algorithm for calculating voltage sag characteristics and indices was created in Matlab.

This study presents results for observing forest changes in Sweden using multi-temporal L-band satellite data and is a part of the JAXA?s ALOS Kyoto and Carbon Initiative. An extensive dataset of images acquired by the Advanced Land Observing Satellite Phased Array type L-band Synthetic Aperture Radar (ALOS PALSAR) is investigated for clear-cut detection in boreal forests in northern Sweden (Lat. 64°14?

Vår uppdragsgivare Filip Asp, på Cochleaimplantat-sektionen vid Karolinska Universitetssjukhuset i Huddinge, utvecklar en ny psykoakustisk mätmetod som är ett ljudlokalisationstest (LLT) för små barn. För att jämföra den med dagens psykoakustiska mätmetoder för små barn har en litteraturstudie och intervjuer gjorts. I samband med detta undersöktes även barns hörselutveckling då det finns en nära relation till mätmetodernas utformning. Efter att ha identifierat de psykoakustiska mätmetoder som i nuläget finns tillgängliga jämfördes dessa med LLT och vi anser att LLT kommer vara till nytta vid diagnostik, habilitering och forskning. I nuläget styrs LLT:s applikationer av MATLAB tillsammans med insticksprogrammet Playrec. Om mätmetoden skulle göras om ville uppdragsgivaren veta vilket programmeringsspråk som var till störst nytta för metoden.

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.

This thesis is done in cooperation with SWECO Energuide in Växjö. They have been assigned by SKB in Oskarshamn to renew their electrical power supply and the ancillary processing systems in their Central provisional storage of spent nuclear fuel, CLAB. Today in the CLAB facility, the spent fuel is cooled down with water pumps, driven by asynchronous induction motors, where the water is regulated by mechanical valves to the desired flow. After the upgrade, the engines will be powered by AC drives that can control the pumps by changing the rotational speed and thus change the water's cooling effect on the nuclear fuel. In this study, I investigated the interference AC drives causes the feeding network and how to go about averting them.

Detta examensarbete har utförts på Saab Support and Services i Arboga. Syftet med examensarbetet har varit att ta fram en modell i Matlab som skall beräkna antal motorbyten, och hur många stora motortillsyner (Check 3) det kommer att bli. Detta skall utföras för att få en så kostnadseffektiv drift som möjligt fram till valt slutscenario, med 40 SK60 det vill säga 80 stycken RM15 motorer i drift. De scenarion som har påverkat projektet har varit 2014 VT, 2017 VT samt 2020 VT. Projektet har delats upp i två moment, där det ena har varit att skapa en databas i Excel för alla motorer och det andra är ett program i Matlab som skall bearbeta all data från Excel, för att på så sätt kunna få ut det mest optimala tillvägagångssättet.Det som vi har kommit fram till är att scenario 2014 VT kommer att uppnås med de aktuella motorer som finns tillgängliga idag utan att någon motor skickas iväg på Check 3.

Det här rapporten är en del av mitt examensarbete för högskoleingenjörsexamen i elektroteknik vid Växjö Universitet, MSI. Arbetet är en del av ett större projekt kallat Kranstyrningsprojektet som bedrivs av Växjö Universitet, Rottne Industri med flera, vars syfte är att underlätta för förare att kontrollera den kran som finns på Rottnes skotare. För projektet har det använts en laborationskran och nu har önskemålet varit att det till kranen ska installeras ett nytt styrsystem från dSPACE. Dessutom vill man att nya givare ska sättas på kranen och kopplas till dSPACE. Man vill även ha en manual för att nya studenter ska kunna använda systemet.

In today?s fast growing and closely connected society, a reliable and energy efficient transportation system is more than ever desirable. Nowadays the significant part of the transportation sector?s energy demand is supplied by fossil fuels.Improving energy efficiency in combustion engines will result in reduction of fuel consumption and CO2 emissions. A modern internal combustion engine has an efficiency of 30-45 %, where the most energy loss occurs as result of heat losses in the exhaust and cooling systems.
