Energieffektiv design av ett inbyggt flashminneshanteringssystem
The report is the result of a master thesis at ENEA AB during the fall of 2009. Itaims to create a specification of flash memory management system which focuseson power efficiency and low RAM usage for embedded systems, and to design andimplement a prototype of such a system to facilitate further development toward thecreated specification. The system used by ENEA today is a Flash Translation Layer(FTL). It has a complex structure which prohibits modifications and customization,therefore a new flash memory management system needs to be developed.The suggested solution uses a translation layer called Metadata FTL (MFTL), wherefile system metadata and userdata are separated from each other in order to improveperformance. The partition holding userdata uses a block-level mapped translationlayer system called Fully Associative Sector Translation FTL.
The Determinants and Impacts of Executive Stock Options
The thesis main objective is to establish the determinants for granting executive stock options and to examine their impact on performance for firms listed on OMXS30. The analysis is based on accounting data gathered from annual reports and Thomson Datastream. The empirical results display that firms grant stock options to mitigate the principal-agent problem. Furthermore, risk proves to be positively significant with executive stock options, implying that either executives increase the level of risk after being granted stock options or influence the decision of the remuneration towards stock options when the firm increase the level of risk, in purpose to boost the expected value of their options. No relation between executive stock options and firm performance could be established..
Hälsobesvär vid icke-toxisk kemisk exponering: Effekter av negativ affekt och luktvalens
Tidigare forskning har funnit delvis motstridiga resultat för hur företagsledningens och styrelsens egenskaper påverkar bolagets värde. Enligt vår vetskap har inga studier genomförts på svenska data. Syftet med denna uppsats har varit att klargöra om det finns något samband mellan ett företags värde (mätt som market-to-book) och ett antal demografiska faktorer hos företagets ledning och styrelse. Detta har testats med hjälp av årsredovisningar och finansiella data för börsnoterade bolag under perioden 2010-2012. Genom multipla regressionsanalyser har vi bland annat funnit att styrelsens storlek har en positiv effekt på bolagets värde och att andelen kvinnor i styrelsen påverkar värdet positivt.
Utformning av sidoområden med hänsyn till vägens livscykelkostnad
Single vehicle accidents are one of the most common types of accidents that occur on the Swedish road network. Depending on the design of the road, the presence of a crash barrier and embankment on the roadside, the outcome of a roadside collision can lead to serious injuries and even deaths.The aim of this project is to investigate the possibility of improving road safety by designing the optimal roadside area based on the results of a life cycle cost analysis (LCC).The questions that have been answered during the duration of this project are:1) Describe the current technical solutions for roadside area design and the various barrier types used in Sweden.2) Complete an existing mathematical model that has been developed by Hawzheen Karim, for calculating life-cycle costs for various roadside areas.3) Calculate and compare the life cycle costs for the side area with a barrier and without a barrier.By performing an analysis of the documentation on the current guidelines and rules for shaping the roadside, was it possible to describe the current technical solutions for the formation the roadside as well as the current roadside barriers in use today. A mathematical model for calculating the life cycle costs of different barrier types had already been developed by Hawzheen Karim. This model was supplemented so that it could calculate life-cycle costs of the roadside region with and without a barrier. After the model was completed, an analysis was performed to obtain life-cycle costs of a roadside with and without a barrier.The result showed that there is a clear relationship between the slope inclination, fill height, and the rate at which the costs rise.

Pressning och hantering av halm som energiråvara
I?ve tried to find the most effective and cost effective way to harvest straw for energy recovery.You can choose between round bales and big square bales. Square bales are the cheapest way to produce straw for fuel recovery because you can optimize the length of the bales so they fit the transportation equipment.In the Malmö area the average days of harvesting hay is 55. The effectively of transportation depends mostly of the speed, the distance and density of the bales. To increase the capacity of bale transportation larger loads and higher density of the bales is necessary.
En jämförelse av molnbaserade realtidsanalystjänster : Skillnader i användbarhet mellan multi-tenant och single-tenant arkitekturer
Internet of Things är ett samlingsbegrepp för den utveckling som innebär att olika typer av enheter kan förses med sensorer och datachip som är uppkopplade mot internet. En ökad mängd data innebär en ökad förfrågan på lösningar som kan lagra, spåra, analysera och bearbeta data. Ett sätt att möta denna förfrågan är att använda sig av molnbaserade realtidsanalystjänster. Multi-tenant och single-tenant är två typer av arkitekturer för molnbaserade realtidsanalystjänster som kan användas för att lösa problemen med hanteringen av de ökade datamängderna. Dessa arkitekturer skiljer sig åt när det gäller komplexitet i utvecklingen.I detta arbete representerar Azure Stream Analytics en multi-tenant arkitektur och HDInsight/Storm representerar en single-tenant arkitektur.För att kunna göra en jämförelse av molnbaserade realtidsanalystjänster med olika arkitekturer, har vi valt att använda oss av användbarhetskriterierna: effektivitet, ändamålsenlighet och användarnöjdhet.

Arbete på väg: Säkerhet vid passerande fordonstrafik
Byggbranschen ställs inför stora prövningar med högt satta mål inom klimat- och energipolitiken och en omfattande påverkan på naturmiljön till följd av dess stora material- och energiomsättning. Demonstrationsprojekt i byggbranschen anses vara ett viktigt steg i utvecklingen av ny byggteknik, men samtidigt finns det ett gap mellan goda resultat som demonstrationsprojekten kan uppvisa och det traditionella arbetssättet (Femenías, 2004) . Samtidigt som det finns ett behov av satsningar på miljöanpassad nyproduktion, finns det också ett stort behov av god förvaltning av våra befintliga byggnader. Bebyggelsen som helhet förnyas väldigt långsamt; drygt 90 procent av de hus som finns år 2020 är redan byggda (Miljövårdsberedningen, 2004). Byggnaders driftsskede har en betydande del i bygg- och fastighetssektorns miljöpåverkan (Byggsektorns kretsloppsråd, 2001), vilket ställer höga krav på fastighetsbolag och fastighetsförvaltare.Syftet med denna rapport är att belysa fastighetsförvaltarens roll i arbetet mot en hållbar utveckling, men också den eventuella problematik som råder med förvaltning av fastigheter som byggs som miljöprojekt.
