I detta arbete behandlas transient simulering i ett 1D-simuleringsprogram, i dettafall Gamma technologies GT-Power. Vad som behöver ändras i en modell för attden skall kunna simulera en motor under transienta driftsfall med godnoggrannhet har undersökts. När detta är gjort, skall det undersökas hur väl dentransient kalibrerade modellen kan simulera en motor med förändrad rörgeometripå insugs- eller avgassidan, och vad som måste omkalibreras om detta inte ärfallet.Den viktigaste slutsatsen av detta arbete är vikten av att ha en korrekt framtagenkompressormapp i modellen. Den som fanns tillgänglig under arbetet hade baramätdata ned till 70000 rpm. Detta resulterade i en överskattning av massflödet iden lägre regionen i den av GT-Power framställda kompressormappen.

There is little knowledge about abuse of anabolic androgenic steroids (AAS) in Sweden. Thispaper aims to explore, from a discourse psychological angle, how persons with experience ofanabolic androgenic steroids (AAS) construct there identities.The theory and method used as a frame for the paper is discursive psychology, depending on thefocus in the paper of human beings use of language in the construction of identities. Forcollection of data interviews were made. The six respondents al had experience of use of AAS.The interviews illustrated how users of AAS speak about AAS, and create there identity, inrelation to AAS. In the interpretation of data we used two different tools, used by discursivepsychologists, interpretative repertoires and subject positions.

Detta projekt är ett examensarbete för kandidatexamen som är obligatorisk för alla studenter. För att ta ut examen måste jag lämna en skriftlig rapport om vad jag har gjort. Redovisa simuleringar och mätningar på olika kretsar. I mitt fall var jag intresserad på att studera hur varvtalet på en likströmsmotor kan regleras med hjälp av olika metoder.  Detta är mycket utmanande för mig eftersom jag inte har sett så många lösningar på detta problem. Jag kommer att använda kunskap, teknik och komponenter från Kraftelektronik för att utföra mitt arbete. Det blir mycket intressant att med dagens utveckling av tekniken se hur olika metoder kan användas för att undersöka hur kraftelektronik kan användas i kontroll av varvtal, frekvens och rotationsriktning av elektriska maskiner. .

The purpose of this essay was to examine whether small businesses can avoid ac-counting crimes with a well-conducted internal control system. The questions we asked ourselves was, whether and if so, companies can prevent this from happening by using a internal control.In this essay we used a qualitative approach. Essential information was given to us from four different interviewees. We also worked from an inductive approach which means that we interviewed people without any earlier research to build on. The method also had a hermeneutical approach, which means that we made different interpretations based on the reference framework and the empirics.After the study had been carried out, we concluded that all evidence from this essay suggested that even small businesses need an internal control to protect their business.

En majoritet bland ledare i olika organisationer har en bakgrund som storasyskon eller ensambarn (Hudson, 1990). Denna studie genomfördes för att få svar på om personer med ledaransvar skiljer sig åt gällande syskonplats och locus of control jämfört med de personer som inte har ledaransvar. Ledare och medarbetare på en statlig myndighet svarade på en enkät gällande plats i syskonskara, erfarenhet av ledarskap och locus of control. Resultatet visade att sistfödda i detta urval hade en högre grad av intern locus of control än förstfödda vilket kan tyda på en annan typ av sistfödd på denna myndighet. Urvalet var dock bristfälligt (N = 48) och slutsats kunde inte dras utan att riskera ett felaktigt resultat..

The thesis was performed at Forsmarks Kraftgrupp AB in the department ofmechanical engineering, FTCM. Forsmark nuclear power plant has had problems with cracks in some of the controlrods which are placed in the reactor at Forsmark 3. To investigate the cause of this,material samples were taken from five of the damaged control rods. This sampling ofthe rods resulted too short rods to be transported in the shipping container to theinterim storage facility for used nuclear fuel in Oskarshamn. Control rods are crucial components in a nuclear reactor, regulating the reactoreffect by blocking or unblocking fuel rods. Control rods which have been in thereactor are always handled under water in order to protect against the radiation theyemit. The task was to design a control rod adapter that extends the control rod sotransport can be performed from Forsmark. The goal of the work was a complete setof blueprints so the control rod adapter can be manufactured and mounted on theshort control rods and then be transported to the interim storage facility. The work began with mapping of how control rods normally being handled from thereactor to the interim storage facility.

Modern democracies rest on a foundation of values essential to their prosperity. Two of those values are freedom of speech and political equality. To many, these values appear to coexist effortlessly. However, what this thesis aims to expose are some of the problems that quickly arise when attempts to interpret the values fail.The thesis investigates a specific US Supreme Court ruling called Citizens United. The ruling enabled corporations and unions to use their own treasuries for unlimited independent political expenditures.

Värnamo Elnät owns and operates a ripple control system which is used to control loadsespecially when the grid is heavily loaded and for control of street lighting. This report aims atclarifying technical and economic aspects of the ripple control system?s future. The system wasinstalled from 1975 and onwards and its use was greater in those days when the controllableloads where greater then today, the current controllable load level is about 3 MW. The reporthighlights three different aspects of the ripple control system?s future ? retain the currentsystem, reinvest in a newer system or discontinue the system.In the report the author also discusses relevant connections to Smart Grids and future meteringsystems and tariffs.

We have performed a case study on Acne Jeans, a creative Swedish fashion company, which initiated a cooperation with the Swedish venture capital firm Öresund. The aim of our paper was to examine what motivates a venture capital firm to transform the management control system of a creative company, into a more formal system of control. Main results: Öresund did not have an excessive impact on the management control system of Acne Jeans, due to three main reasons. First of all, Acne Jeans had a satisfactory management control system prior to the cooperation. Furthermore, the relationship between the two parties was characterized by mutual trust.

The aim of this study is to examine and analyze how management control mechanisms evolve within an organization when a requirement of return on equity is imposed, as well as why the mechanisms evolve the way they do. A case study was performed on Samhall, a Swedish state-owned company, which has the aim to help people with disabilities develop by providing meaningful work. The framework provided by Samuelsson, defining five means of control in organizations was used to structure the study. Further, theories within New Public Management have been used to provide the reader with a proper background to the research area. Theories from the institutional field of organizational research have also been used to provide further depth to our analysis.

A pilot study conducted on four patients, which we received from the Sahlgrenska University Hospital, who were all potential candidates for a cochlear implant. We fitted our test subjects with a pair of frequency compressing hearing aids called Phonak Naida V SP during the study and let them evaluate them for about seven weeks. Measurements made with monosyllabic words throughout the study showed significant differences in speech perception (p?0.05) compared to their regular hearing aids in 3 out of 4 cases. De-activation of the frequency transposed function showed significant decreases in 3 out of 4 cases compared to when it was activated.All test subjects were satisfied with the new hearing aids and chose to keep using them at the end of the study..

Background: It is common that children and adolecsents with Aspergers syndrome have impaired motor skills and are less physically active than neurotypical children and adolecsents. Studies conducted on neurotypical children shows that children and adolecsents who are regular physical active also have a good motor control and a good physical self-esteem. The purpose of this study was to investigate the physical self-esteem of children and adolescents with Aspergers syndrome. Study Group: 36 children and adolescents aged 9-15 years with a diagnosis of Aspergers syndrome was asked to participate in the survey. 18 children, 16 boys and 2 girls, responded to the questionnarie about physical self-esteem which 17 of the answers could be used in the study.

Aim Developmental Coordination Disorder Questionnaire 2007 (DCDQ'07) is an international survey tool based on parents' estimation of their child's motor coordination skills. The purpose of this study was to investigate the validity of a Swedish version of DCDQ'07 by finding out how the classification of Developmental Coordination Disorder (DCD) via DCDQ'07 is consistent with the classification of DCD via the motor impairment test, Movement ABC.MethodIn the context of a larger study, a Swedish translated version of the parent survey DCDQ'07 were sent to 4000 randomly selected families with children aged 8 - 10 years in Stockholm County. The classifications "DCD" or "NOT DCD" with cut-off values ??of 56 (9 years) and 57 (10 years) were applied. Forty families were selected from 410 registered responses.
