Design av slutsteg med digital PWM-teknik för gitarr
Softube has developed DSP-card and software for simulation of the sound of old tube amplifiers. The purpose with this thesis is to design a compact amplifier with high power to function together with the DSP-card and build a unit that can replace several other guitar amplifiers. The advantages with that kind of solution could be that it would be cheaper, easier to carry and easier to stor than the real amplifiers. The amplifier that has been designed is of class D type with digital PWM modulator. There is several types of amplifier modules on the market that use analog input signal, but if one of them would be used a D-A converter is needed on the DSP card.
Automatisk nivåreglering av strålkastare
To be allowed to sell Z-suspended vehicles with dipped beam Xenon or LED lighting, Scania have to develop automatic headlight level control. This master?s thesis aims to be the foundation to that development.The thesis consists of several parts; a market analysis of how competitors to Scania and the general vehicle industry solve this problem; several available principles for detecting the amount of control needed; the construction of a test station for sensors, a control unit and components connected controlled by the control unit; a further theoretical and practical development of one principle ? one rotational sensor connected between the chassis and the back drive axis; a state flow model programmed in Simulink that produces the control signal for the headlight leveling from the sensor input.Lastly the thesis gives some recommendations to the further development and implementation of automatic headlight level control on Scania vehicles..
The Sound of Fashion : en studie av tre svenska modevarumärken
Spanska sjukan var en världsomfattande epidemi, en pandemi, som drog över världen i flera influensavågor mellan 1918-1920. Syftet har varit att ta reda på hur Säters hospital drabbades av och hanterade influensautbrottet 1918. Med hjälp av överläkarens årsberättelse för 1918 har jag lyckats få fram att 40,7 % av alla patienter blev smittade av spanska sjukan varav 15,3 % av dem avled till följd av sjukdomen. 529 personer smittades av spanska sjukan på Säters sjukhusområde varav 57 personer avled, vilket motsvarar 10,8 %. Av de 529 smittade männen och kvinnorna avled 12,6 % kvinnor (34 stycken) och 8,9 % män (23 stycken) till följd av in-fluensan.
Erfarenhetsöverföring vid svenska utlandsstyrkan : Vilka faktorer påverkar och hur?
The purpose of this paper is to identify the factors affecting the experience transfer at the rotation of the missions. This is to identify the respective influences are inhibitory factor, which contributes to a less efficient transfer, or if it contributes to a more efficient handover. The method used for the production of this paper is a qualitative case study of squad leaders who have done service in Kosovo or Afghanistan. Through interviews with focus on the transfer of experience, both on individual and organizational level, the factors that affect are being identified. The model used is expressed in a general perspective, where each factor is categorized as inhibitory or contributing to success, and if it appears on an organizational or individual level.
Medverkan och inflytande : om brukarnas roll i socialtjänstens kunskapsutveckling
The main purpose of this essay was to study the program "Nationellt stöd för kunskapsutveckling inom socialtjänsten" ("National support for knowledge development within the social services") from the National Board of Health and Welfare on the basis of how such a development, as represented by the program, could affect clients' possibilities to participation and influence within the social services.To respond to the purpose I used the following questions at issue:* How is client participation and client influence defined in the program?* What arguments for and/or against client participation and client influence are stated?* Which patterns and similarities/differences are possible to discern between the municipalities and universities that participated in the program when it comes to client participation and client influence?The study was conducted as a document analysis. I studied documents from the program both on a national and a local level. The essay uses empowerment theories and theories concerning client participation and client influence. The main conclusions were that on the national level the authors of the documents spoke with caution about their view on client participation and client influence and expressed that it had to be balanced against the rights of the citizens and the social workers for example.

Hörbarhet i praktiken : En Actor Network analys av arbetet kring hörbarhet
Abstrakt Tv-branschen är en jätteindustri som styrs av ett fåtal stora sändningsnätverk. I Sverige är den största distributören Sveriges Television (SVT) och på grund av detta så är sannolikheten att personer som arbetar inom ljud i Sverige någon gång kommer att arbeta på projekt för dem väldigt hög.I min uppsats har jag utfört en Actor Network-analys av empiriska studier jag utfört på postproduktionsbolaget Europa Sound and Vision. Med hjälp av analysen vill jag undersöka vad begreppet ?god hörbarhet? består av och därmed kunna definiera uttrycket tydligare.Jag jämför sedan SVTs syn på hörbarhet med den jag fått fram genom dessa studier för att till slut ändra på den nuvarande synen och på det regelverk SVT har..
Europeisk medborgardialog? : En implementeringsstudie av Plan D som i demokrati,dialog och debatt
In an effort to strengthen democracy in the union, the EU in 2005 took a new approach to communications policy to reach out to the citizens. The strategic document "Plan D for Democracy, Dialogue and Debate" was accompanied by two other documents, and the three of them were the core of this policy. Both democracy and communications work means at EU level a higher complexity than in the nation-state arena. Objective of this study is to examine how the implementation of Plan D has turned out in a democracy renewal perspective. To achieve that answers are sought to questions concerning the goals of Plan D, how they are still present today, what happened in practice regarding the efforts that are highlighted, and how the substance of the activities can be judged from a democratic theory perspective.

Data was collected by group interviews and document studies. To get all kinds of teachers, from pre-school to year six, in the groups the sample was made by the headmaster of the schooldistrict. Since it is a case study the findings can not be considered as general, but they can hopefully contribute the pedagogical discussion and future research.The findings show that there exists a difference between the expectations on policy level on the one hand and on the team level on the other hand.
Är musik konst? - En undersökning av fem ljudskapande människors syn på sitt eget och andras skapande
Syftet med den här uppsatsen är att undersöka och synliggöra några olika sätt att se på musik som konst (eller icke-konst). Som metod har jag valt att göra kvalitativa intervjuer med fem personer som, på olika sätt och inom olika genrer, skapar musik eller ljudkonst. I intervjuerna har jag försökt ringa in de olika personernas syn på konstbegreppet, på musik i förhållande till detta begrepp samt på deras eget skapande. Resultaten visar på fem individuella synsätt och personliga definitioner av konst. Vilka intervjupersoner som delar varandras synsätt varierar mellan de olika frågeområdena och några generaliserbara slutsatser går inte att dra, vilket inte heller har varit målet med undersökningen.
Klasser som påverkar : Om klasskillnader och förändring i politiskt deltagande under perioden 1968 - 20000
The purpose of this thesis is to see how small differences in a store can affect the customer behavior. The changes consist of auditory and visual sensory cues. Since many companies today makes a lot of changes in their styling element, but without knowing how it really affects the customer behavior we thought it would be interesting to see by doing an experiment at IKEA. The study is therefore based on a quantitative research method, where theories have been described and from which hypotheses have been derived to test the theories. The experience took place at IKEA during two weeks where 5732 observations were made.The result from the experiment is that the sensory cue sight makes individuals spend more time in the environment but not creating attention.
Arbetslöshet bland utrikes födda på den svenska arbetsmarknaden : En empirisk analys av vilka kommunala faktorer som kan påverka den höga arbetslösheten bland utrikesfödda
Unemployment amongst Swedish citizens is higher within the group which falls under the designation foreign-born. The aim of this thesis is to examine which municipal factors that can explain the differences in unemployment amongst foreign-born relative to native born.The empirical models are examined with both cross-sectional data for the year of 2010 and panel data for the years of 2002-2012. The examination is implemented through a linear regression analysis of the type Ordinary Least Squares (OLS) and Fixed Effect regressions. A theory section will be presented where the theory on Non-Accelerating Inflation Rate (NAIRU), theories on discrimination and country-specific human capital are illustrated.The result from the cross-sectional data shows that the amount of foreign-born, the level of foreign-born immigrated from Nordic countries have a significant negative effect on unemployment amongst foreign-born. The general unemployment shows a significant positive effect on the unemployment amongst foreign-born.
