The aim of this paper has been to examine personas role in the development phase and whether or not some of the criticism that have aroused against personas is valid or not. In this paper we examine the benefits as well as the downsides of working with personas both from a scientific point of view but also from the experiences of a small company located in the north of Sweden. Since personas much like many other powerful tools have pit falls aswell as do's and don'ts this paper looks to clarify what role personas should take aswell as how to minimize risk and maximize the usefulness of personas..

This thesis aims to identify the building integrated photovoltaic solutions available in the market with respect to general pros and cons of different systems and a technical description of there attachment system. Investigate and provide examples of various building integrated photovoltaic solutions in Sweden and describe the experiences and results of these projects.The methods used to obtain relevant information are interviews with individuals involved in significant projects and a thorough search of different solutions from solar suppliers.The conclusion is that solar energy is needed for a sustainable society. There are endless opportunities regarding BIPV, with many companies with different products and individual solutions. But so far it?s not so customary in Sweden.

This paper aims to examine how, and if, music is being used integrated in other subjects thanmusic in school. The study is based on qualitative interviews and I haveinterviewed fourteachers, regardless of whether they use music a lot or not.The questions the study is basedon are if there might be a connection between theteachers' own feelings for music andwhether they use music inschool or not, how music is being used and does the use of musicgive any effects?The result of this study shows that there can be a connection between the teachers ownsfeelings for music and the fact if they use music when they teach or not. One of the teachersI?ve interviewed had bad music experiences and didnot use music in her teaching.

The purpose with the paper is to theoretically investigate how sensory experience and positive affect in contact with outdoor environment can promote health by 1) develop a model of the sensory and emotional processes based on multiple code theory (Bucci, 1997) and 2) examine if this model can increase understanding of the processes that takes place in outdoor recreation, the way this is described in environmental psychology research and theory. The paper starts by introducing research and perspectives concerning outdoor recreation. Different theories of nature?s health promoting effects are described. These include the restoration theories of Roger Ulrich and Steven and Rachel Kaplan, theories more concerned with outdoor activities and a theory combining these two perspectives called instorative theory. After this sensory and emotional information processing is examined through the works of Wilma Bucci and Jean Ayres. Antionio Damasio?s theories of emotion and Daniel Stern?s concept of vitalityaffects are than introduced to extend this reasoning.

I will in this paper give an introduction to the subject fields systemdevelopment, groupdynamic, conflicts and kommunication. The paper will fokus on what systemdevelopmentgroups can do before and during a project to support the teamwork and what systemdevelopmentgroups kan do to overbuild destruktive conflicts..

To be able to compete on the market environmental Management System has become an important part of operations work. However, many companies still haven?t implemented an environmental management systems due to lack of time and the high costs. One of the companies with this problem is Falu Bildemontering. Their goal is to accredited according to the ISO 14 001 certificate.

This paper is a study of corporate governances in the municipal of Stockholm. The purpose of this paper is to enlighten the problems and opportunities for the corporate governances of the wards in the municipal of Stockholm. The municipal of Stockholm is made up of 18 relatively self-governing wards, whose activities bear a resemblance to one and other. Therefore we have specified our survey to corporate governances in the ward of Skarpnäck (Skarpnäcks stadsdel), to be able to use this ward as an example to corporate governances in the entire municipal of Stockholm. The essay emanates from the important management theories: Budget, Integrated Management system (ILS), Benchmarking and Balanced Scorecard.The essay is based on interviews and a poll survey we conducted in the administration of the ward of Skarpnäck, and also based on interviews with Stockholm?s city hall.

The thesis work of 15 credits has been performed to interest of Norrtälje ElektronikPartner AB (NEP) in Norrtälje. The aim of the thesis was to develop a prototype for an integrated digital multimeter, designed for one of NEP's proprietary test systems. A digital multimeter module according to NEP's requirement specification, such as physical size and accuracy should be constructed. The module should be able to measure current, voltage and resistance.The final circuit was based on the chosen analog to digital-converter, Maxim integrated´s Max134, which is the main component of the circuit for this instrument. A circuit diagram and PCB layout were made. The result of this project is a constructed DMM board.

This paper aims to derive the Black-Scholes equation for readers without advanced knowledge in finance and mathematics. To succeed, this paper contains a theoretical chapter in which concepts such as options, interest rate, differential equations and stochastic variable are explained. This paper also presents the theory of stochastic processes such as the Wiener process and Ito process. In the chapter on the Black-Scholes model the Ito process is used to describe price of shares and with the help of Ito's lemma Black-Scholes equation can be derived. In the paper, assumptions are listed that apply to the Black-Scholes model and then uses the Black-Scholes equation to calculate the price of a European call option.

This essay is a comparative empirical study of ethnic integration mainly of the Russian-speaking minorities in the three Baltic states (Estonia, Latvia and Lithuania) in a post-communism setting. As Lithuania has a Polish minority that is as large as the Russian-speaking, they too shall be included in the study but not as thoroughly as the Russian-speaking minority. Thus the problem is: to what degree are the ethnic minorities integrated with the titular nations in Estonia, Latvia and Lithuania? In order to study ethnic integration I have set up a theoretical framework largely based on Weiner?s theory of integration. The theoretical framework focuses on three dimensions: Citizenship, Identity and Segregation.

Syftet med arbetet var att undersöka hur olika reaktionsbetingelser skulle påverka syrgasdelignifieringen av en sur sulfitmassa. De betingelser som undersöktes var utbyte, slut-pH, viskositet och kappatal. Massan som användes kom från Nordic Paper Seffle och alkalit som användes var magnesiumoxid. Syrgasdelignifiering av massan gjordes  i autoklaver i ett PEG bad där tid, temperatur och alkalisatser varierades.Resultaten visar att alla utbyten låg mellan 90-97% och att även de mest aggressiva betingelserna bara gav en viskositets reduktion på 260 enheter, motsvarande 19% av den totala viskositeten.Slut-pH för syrgasavluten hamnade mellan 6,5-9,4 beroende på alkalimängd och temperatur under delignifieringen. Slut-pH minskade när mängden alkali hölls konstant men temperaturen varierades mellan 110-140°C.Kappatalet för massan kunde effektivt reduceras från ett startvärde på 23,4 till ett slutvärde på under 5 med en temperatur på 140°C, alkalisats på 10 kg/ODT och en tid på två timmar utan större förluster av vare sig viskositet eller utbyte.En ovanligt resultat som upptäcktes under arbetet var att delignifieringen tappade i effektivitet med ökad alkalimängd och detta samband gällde vid alla betingelser.En teori om detta kan vara att jonstyrkan i lösningen gör att fibrerna i massan drar ihop sig och att syrgasen får svårare att reagera med ligninet..

Denna uppsats berör försöket med trängselskatter i Stockholms innerstad. Införandet av dessa har under en längre tid varit på tapeten inom politiska kretsar. Diskussionerna har pågått under en femtonårs period och en mängd förslag har debatterats. Den lösning som innebar införandet av trängselskatter på försök klubbades igenom under 2003 och försöket startade i januari 2006. Denna modell är inspirerad av liknande system i andra städer som exempelvis London och Oslo.
