MÄTNING AV LJUDIMMISSION FRÅN VINDKRAFT. VIDAREUTVECKLING AV METOD FÖR MÄTNING
The Swedish government have a goal that wind turbines shall produce 30 TWh by the year 2020, compared to about 3,5 TWh produced in Sweden during 2010. To minimize the disturbance that wind turbines create the Swedish Environmental Protection Agency has stated a guideline value that noise from wind turbines at nearby residents shouldn?t exceed 40 dBA, at 8 m/s wind speed. With advanced calculation models, like Nord 2000, the emitted sound from future wind turbines can be calculated at an early stage to optimize the power production without exceeding the 40 dBA. When the turbines have been built there is a need to verify that they really are within the guideline.
Management of Private Equity Investments: A Study of Swedish Biotech Investment Managers
The Private Equity industry has over the past years been booming and major external environmental changes have made the industry transform rapidly. Increased competition between Private Equity firms is one of the reasons why the industry has been and is being forced to focus more on addition of value through increased operational management. Consequently, the focus of value addition is by some said to be transferred away from deal making and financial skills, and into active operative management. This case study investigates how the portfolio management, and more specifically the measuring and management of performance, is carried out in a number of leading Swedish Private Equity funds with investments in the biotech sector. The biotech sector is characterized by extensive research and development, and many biotech companies often lack income and other measurable financial parameters in the initial phase.
Prestationsmått: Ett verktyg för styrning - eller en rapport bland alla andra. Om mellanchefers tillämpning av prestationsmått i styrningen av operativa enheter.
A performance measurement system can be used as a means to evaluate past performances and to communicate prioritizations. It has also been proposed that a performance measurement system can serve as a method to execute strategies, guide in operational decisions and constitute a tool for making the organization more efficient. Yet one may question if such a system will ever reach this capacity if operating managers do not utilize it as a management tool, but rather treat it as a mere report in the bunch. This paper explores how middle managers in fact apply performance measures and what obstacles there are to integrating them in the management of subunits. Furthermore it serves to investigate whether these managers experience a conflict between how they are expected to use the measures and what they deem possible to adopt.

Att vårda en närstående i hemmet vidlivets slut : En livsberikande erfarenhet?
Background: Peripheral arterial disease (PAD), as a consequence of atherosclerosis in the arteria of the limbs, affects one of ten Swedes older than 65. PAD can develop slowly and silently, and involves an increased risk for cardiac infarction and stroke. Measurement of the patient´s ankle blood pressure and calculation of the ankle-brachial index is an evidence-based method to discover PAD. Objective: To investigate how district nurses and general practitioners perceive this method of examination and experience possible obstacles to why it is not more commonly applied at primary health care centres. Method: Data collected by semi-structured interviews have been processed by qualitative content analysis with a manifest onset.

Strömkontroll till aktiva magnetlager med noggrann och störningsreducerad strömmätning
There is always a need for more effective ways to store energy in order to reduce the human impact on the environment. One step on the way can be the use of flywheels as kinetic energy storage devices. Low frictional losses are essential for a flywheel to be effective. To minimize these losses active magnetic bearings (AMB) can be used to keep the shaft centered instead of the more conventional ball-bearings. AMBs use actuators and a fast control system that needs correct and noise-free measurement data of the shaft position and the current in the actuators to work properly.This thesis explains the process of constructing power electronics and a current measurement system for active magnetic bearings (AMB).
Från myt till Ptolemaios: Geografin under antiken
This paper deals with the development of scientific geography during Antiquity from its mythical background before the seventh century BC to Claudius Ptolemy during the second century AD. The main focus is on questions concerning the shape of the earth, its place in the universe, size and mapping of the earth. Already before 400 BC, the idea of the earth as a globe was firmly estabished. During classical time, Aristotle used empirical and rational arguments to prove that the earth was a sphere and that it was situated motionless in the center of the universe. In the third century BC, the first reasonably correct measurements of the circumference of the earth was carried out by Eratosthenes.
Svensk vindkraft
Sweden's drinking water quality is considered to be high partly due to a high quality of the raw water and a well developed sewage infrastructure. Despite this, there is water contamination that could be prevented by installation of a sophisticated early warning system. Some of the major players in the production of drinking water have already invested in different types of early warning systems to ensure drinking water of high quality. There are various forms of early warning systems where automatic monitoring of E. Coli is an interesting alternative.
Nedskrivning av Goodwill. Bias och kulturella skillnader i nedskrivningsprövningen - case: Finland och Sverige
Bakgrund och problem: De noterade finska och svenska företagen har sedan redovisningsår2005 varit tvungna enligt IFRS-regelverket att utsätta sina goodwillposter för årliganedskrivningsprövningar. Förfarandet har förväntats öka på redovisningens relevans mensamtidigt har den också kritiserats för att öppna ett fönster för manipulation och bias. Problemetmed förfarandet är att det innefattar en hel del personlig bedömning och är för allmänheten enrelativt ogenomskinlig händelse. Den tidigare forskningen har för mestadels koncentrerat sig påden amerikanska marknaden och varit oense ifall den nya kutymen är lyckad eller inte. Diverseundersökningar har lett till olika resultat angående bias inflytande över nedskrivningsprövningar.Tillsvidare har IFRS-hemisfärens norra del (Nord Europa) dock inte berörts i denna forskning.Syfte: Syftet med denna uppsats är att ta del i den tidigare diskussionen med att undersöka ifallde i Finland och i Sverige utförda nedskrivningarna varit igenomsnitt befogade och ifallberättigade ekvivalenta skjutits upp.
Migration och arbetsmarknadsintegration - den tyska återföreningen
Title: Migration and Labor Market Integration ? the German Reunification Since the German reunification former East Germany has been struggling with rising unemployment numbers and extensive emigration. The East German Länder are still well behind the West German and even though Germany unquestionably is united politically the old border divides the economy ? and the labor market ? in two. This thesis aims to describe the reunification process of the East German and the West German labor markets, and in particular the role of migration in this process.

Identifiering av parametrar för tillståndsbedömning av en vattenkraftstation
The report begins with a general inventory of possible technical faults in a hydropower plant and of possible fault indicating measurements. Then an investigation is made concerning a few different faults. Based on this investigation a choice on seal box condition and water leakage is made as problem for a more thorough examination, in which it is concluded that the turbine water leakage is larger when the turbine is put into operation. The examination ultimately results in a computer alarm for faults related to the seal box. Finally a few things are mentioned about flow measurement and pressure measurement in relation to the project as a whole..
Snabba lån : Processen för finansbolagens riskhantering av snabba lån
Syftet med föreliggande studie var att försöka reda i litteraturen kring två välkända begrepp inom Affective Forecasting nämligen Impact Bias, som innebär att människor har en tendens att överskatta i vilken utsträckning de kommer att uppleva en viss känsla i en framtida situation än vad som senare visar sig vara fallet, och Empathy Gaps, som innebär att människor har en tendens att underskatta i vilken grad känslotillstånd kommer att påverka deras preferenser i en framtida situation samt pröva dessa begrepp i en och samma enkätundersökning. Etthundra sextiotvå studenter, slumpvist uppdelade i två grupper, Känslogrupp och Preferensgrupp, deltog frivilligt i undersökningen. Enkätundersökningen var en mixad design med grupp (känsla kontra preferens) som mellangruppsfaktor och förtest kontra eftertest som inomgruppsfaktor. I studien visade samtliga gruppers resultat i linje med Impact Bias teorin, dvs. att deltagarna i både Känslogrupp och Preferensgrupp skattade lägre i eftertest (actual) än pretest (forecasting).
