Beräkning av energianvändning i svenska småhus
An energy calculation model for Swedish houses that is fast, flexible and user-friendly has been developed within the framework of this thesis. The model also provides a set of actions which may be investigated in the model based on savings and payback period. Energy use in a house depends on the technical conditions, such as building envelope and heating systems, which outdoor climate the house is exposed to and who lives in the house. Energy use for a house can be divided into heating, hot water and household electricity. There are several methods to calculate the energy use of a house. This report summarizes the methods that may be suitable for a fast and user-friendly calculation model.
Emotionell intelligens : En studie av den dskursiva produktionen av begreppet emotionell intelligens i ett organisationssammanhang
Emotional Intelligence (EI) is a highly used concept in contemporary organizations, especially in the recruitment process or education of employees and managers. The aim of this study was to examine the discursive production of the concept emotional intelligence and how it, linked to an organizational context, is expressed in web-based articles and course homepages. In total 11 texts related to emotional intelligence and organizational contexts were used as the object of study. A three-stage model was used as a method for analysis. The model included a content analysis, argument analysis and a deconstruction analysis in order to expose what was said about emotional intelligence and how it was said.

Limitations: The efficiency is tested solely through the chosen portfolio strategies: low Price-Earnings ratio, low Book-to-market ratio and low stock prices.
Visuell identitet : Några estetelevers tankar om att framställa sig själv genom stil och hur det kommer till uttryck i praktiken
Denna studie behandlar begreppen process och produkt. Syftet är att genom ett hermeneutiskt perspektiv undersöka några bildlärares syn på begreppen process och produkt i bildundervisningen på högstadiet. Tidigare har fokus legat på elevers färdiga produkt men idag är bedömningen i bildämnet mer fokuserad på elevers process (Skolverket, 2012:3). Undersökningen genomfördes genom kavlitativa intervjuer. Intervjufrågorna är förankrade i Lindströms (2002:4-5) process- och produktkriterier.
KORTSIKTIG PRODUKTIONSPLANERING I MINDRE FJÄRRVÄRMESYSTEM : En studie vid Strängnäs Energi AB
District heating covers around 80 % of the heating demand in apartment buildings and 10 % in single-family homes in Sweden. In the year 2010 the total input of energy to the Swedish district heating grids was about 70 TWh, which corresponds to 11 % of the total energy input to the whole energy system in the country. Through the combined production of heat and power the CHP-plants often reaches an efficiency of 90 % from energy in the fuel to produced heat and power. In order to keep the efficiency high it is important for the owners of the plant to have good knowledge about the plants performance at different operation points. Strängnäs Energi AB initiated this diploma work together with FVB Sverige ab in order to come up with a program for short term planning of the production of heat and power at the company´s CHP-plant.The work consists of three main parts.
Köpa konsulter via konsult, en tuff match för bemanningsbranschen -Fallstudie av konsultmäklares förmåga att matcha bemanningskonsulter med konsultuppdrag
During the last two decades, temporary staffing has been the fastest growing industry in Sweden. The latest development within this industry is the integration of third-party providers of temporary staffing. Client organizations outsource the process of recruiting temporary workers to intermediaries with procurement management expertise. The concept is called Vendor Management Services (VMS) and aims to standardize decision-making and lower costs through improved efficiency. However, studies have shown that VMS intermediary functions have negative impact on placement matching.
Torkning av flis med restvärme : Metoder för att sänka återledningstemperaturen
The purpose of this study has been to evaluate whether a Low temperature bio-mass dryer could be integrated with the local district heating system in Malå. The aim is to increase the thermal efficiency of the cogeneration plant in Malå, by lowering the temperature of the cooling medium. Another benefit that comes from this is improved combustion efficiency at the power plant, since drying the fuel causes an Increase of the heating value.Simulations has been made in Excel, and with use of linear regression, to find out if it is profitable. Data for this purpose has been supplied by the power company Skellefteåkraft and furthermore SMHI.The result of the Calculations shows that a very efficient bio-mass dryer is needed, if yield of investments should be made possible. An Investment of 4,27 Mkr, in a dryer, could at a such criterium return 60000 kr/year, if the price of the biomass is 190kr/MWh.
Effekter av nya PBL : En studie av processen från handläggning av bygglovsansökan till slutbesked
It has now passed two years since the new site- and construction law, PBL, went into force. It replaced the previous PBL applicable since 1987, and it involves relatively large changes in many different areas of the construction sector. The ambitions of the new law are for instance to simplify and clarify the legal text, increase efficiency in the permitting processes and improve the quality of construction. To achieve this, a variety of changes was made. Some of the most important are: inserted deadline in the processing of building applications, extended assessment of building applications, revised rules about controlplan and quality manager, a certificate is required to start and end the project, an additional meeting is inserted and the construction management of the municipalities will have to do a mandatory visit at the work scene.
Valutamarknadens effektivitet - En studie av växelkurser utifrån UIP med förväntningar
This essay discusses and evaluates the international currency market in regards to efficiency. To prove the theory that, the difference between expected and actual exchange rates is explained by the difference in expected and actual interest rates and the difference in expected and actual inflation between countries, a model was developed. This model was inspired by the paper of Sebastian Edwards (1982), and is based on three theories; UIP, IS/LM and the Efficient Markets Hypothesis. The model uses 16 regressions estimated from three pairs of curriencies: $/SEK, £/SEK and ?/SEK.
Mobilt arbetssätt inom sjukvården och patientens personliga integritet : Klarar patientens integritet att journalen görs tillgänglig för sjukvården mobilt?
In the light of new technology health care is now given the opportunity to form a more mobile way of working that would bring about potential gains in terms of efficiency and quality. On the other hand, a more mobile health care also requires a more generous handling of personal information, something that may raise issues in terms of privacy. This study shows that the privacy of the patient requires two things: (i) that the personal information of the patient is handled in a way that generates her an overall positive expected utility and that (ii) the negative expected utility that each risk of an information leakage causes is offset by the expected utility it also makes possible. The first requirement (i) is shown, in comparison with today?s way of working, to be met due to the potential gains in efficiency and quality in combination with no increase in the probability of informational leakage or negative effects of such a leakage. The second requirement (ii) was also considered met since no separate risks of information leakage could be identified that was not offset by the gains it made possible in terms of expected utility..
Produktionsanalys av: Backa Teaters uppsättning av: UTOPIA 2012. När var du i paradiset senast?
This essay analyzes the production process in connection with the original play Utopia 2012, which premiered at Backa Theatre, Gothenburg, Sweden on 27 October 2012.The aim of the essay is to seek a deeper understanding of this particular production process. No universal process plan was employed when creating Utopia 2012. Therefore, taking into account artistic, technical and administrative aspects of the work, a chronological process map has also been constructed in connection with this essay, in order to clarify each step of the theatrical working process.The theoretical approach is hermeneutic, and the material is based on interviews with key individuals with different professions and functions within the working process in order to gain multifaceted perspectives and results. The interviews took place at Backa Theatre with the exception of those held by telephone with the project?s two producers, both of whom by that time no longer worked at Backa Theatre.The findings of the essay mostly indicate that, with the significant exception of director Mattias Andersson?s artistic vision, no fixed process map nor explicitly articulated common goals were employed in this particular theatre production.
