Empiriska växelkursmodeller för den svenska kronan - Är det någon som fungerar?
The forecast ability of four well-known exchange rate models for theSwedish krona is tested in this thesis. The models that are tested arethe purchase power parity, the real interest differential model, thesticky-price model and a productivity model. In addition to thebenchmark, the random walk, they are also compared to each other.They are all tested on three different horizons one quarter, two quartersand four quarters. The mean squared forecast error criteria and thedirection of change criteria are used for evaluation of the forecastability. Only in a couple of cases are the forecast ability of thetheoretical based models significant better than the random walk..
En indirekt metod för adaptiv reglering av en helikopter
When a helicopter is flying, the dynamics vary depending on, for example, speed and position. Hence, a time-invariant linear model cannot describe its properties under all flight conditions. It is therefore desirable to update the linear helicopter model continuously during the flight. In this thesis, two different recursive estimation methods are presented, LMS (Least Mean Square) and adaptation with a Kalman filter. The main purpose of the system estimation is to get a model which can be used for feedback control.
Analys av mätdata från nätstationer
Fortum has in a pilot project installed metering equipment with wireless communication in secondary substations in Stockholm. So far, the collected data are used only in specific projects.This master thesis was carried out at Fortum Distribution AB in Stockholm during 2013. The purpose of this study is to simplify and enhance the use of data in for example network planning process, by giving suggestions on how data can be managed and giving examples of analyzes that collected data can be used for.The electricity meter which Fortum has installed is a EDMI-Mk10A which is set to measure max/average/min values with a one hour time resolution of the following parameters: voltage (per phase), current (per phase) andactive power and active and reactive energy.In order to analyze the collected data an analysis tool is required. During this thesis two customized tools in Microsoft Excel have been developed, one for sorting data and one for analyzing.One aim of the thesis is to show examples of what collected measurement data can be used for. This work shows an example of analysis of active power, power factor, voltage, occurrence of interrupts and the relationship between outdoor temperature and power.This master thesis has among others resulted in the following advice: Expand the number of secondary substations with measuring equipment.
Konceptutveckling i bostadsbranschen ? en möjlighet till innovation och mervärdeskapande
Alneskolans slöjdlärare Sara Edström anser att deras trä- och metallslöjdssal upplevs som trång, är oändamålsenlig och har brister utifrån de gällande arbetsmiljökraven.Syftet med denna rapport är att slöjdläraren ska få ett underlag som visar hur slöjdsalen kan utformas för att bli effektivare, trevligare och uppfylla gällande lagar och rekommendationer. Underlaget som kom att innehålla en planritning, rivningsritning, rumsbeskrivning och en kostnadsberäkning, ska sedan användas för att få till en verklig förändring av slöjdsalens utformning.Utformningen grundades på boverkets byggregler, arbetsmiljöverkets rekommendationer och slöjdlärarens anvisningar.Resultatet visade att slöjdsalen kan utformas så att den blir mer effektiv, trevligare och säkrare. Till en kostnad av 125 000 kr kan lokalen utformas så att den uppfyller alla regler och rekommendationer samt de flesta av anvisningarna som angivits. .
Strategi, Läge & Varumärke
Goal: To describe which evaluation method is used by Swedish retailers to assess a potential retail location and to describe to what extent the retail brand effects this strategic decision. Design: Analysis of ten interviews with companies within five retail sectors in Sweden. Main study: Indication of what methods are used to evaluate a location and how a company's retail brand affects the decision. Results: Retailers use a mix of theoretical methods to evaluate the location attributes and possible profit. Most common among mixtures was an application of the analog method, residual method or the checklist method in combination with a financial assessment.
Analys av systemfaktorers påverkan på tillförlitligheten i distributionsnät
In this master thesis outage statistics covering tree years from two distribution grids are analyzed with the purpose to deduce which factors yield outages. The statistics are extensive therefore allowing in-depth analysis of both customer and system related factors. From this starting point and as a model of explanation energy not supplied is studied as the consequence and the measurement of the inconvenience caused by outages. Different methods for calculating energy not supplied are developed and studied and put in comparison to the method used in Network Performance Assessment Model, which is the Swedish frame work for regulating electricity distribution.Analysis of the outage statistics show a relation between the type category of customer and outages that can be deduced to the variance and the density associated with that customer category. Prioritization of different customer categories is elevated also in this aspect.
Maskulinitet : en kvalitativ studie om hur maskulinitet kan konstrueras bland unga män, som är aktiva inom lagidrotten fotboll, analyserat ur ett genusperspektiv

Fastighetsmäklare - mycket slit och dåliga villkor?
Fastighetsmäklare har ett rykte att de tjänar mycket pengar utan att anstränga sig. Stämmer detta eller är det bara en bild som media skapat? Med den bakgrunden valde vi att titta närmare på vilka lönesystem för fastighetsmäklare som finns i branschen. Med avgränsning till privatbostadsmarknaden och Stockholm-Uppsala regionen.Syftet är att öka kunskapen om olika lönesystem för fastighetsmäklare på privatbostadsmarknaden.Vi har även tittat på hur det fungerar med sjukpenning, föräldrapenning och a-kassa. Sedan har vi valt att titta på hur en mer traditionell lön ser ut och vilka förmåner utöver lön som kan förekomma.Vi har genomfört två intervjuer angående hur en traditionell eller ?normal? lön fungerar samt fyra intervjuer med fastighetsmäklare angående lönesystem för fastighetsmäklare..
Friheten från fattigdom - En rättighet eller något annat?
This paper investigates whether there is a right not to suffer from poverty. The investigation is being conducted from the theoretical standpoint/view that only civil and political rights constitute justiciable rights and rights proper from a moral stance, whereas economic and social rights constitute mere political agendas or less.In the search of an answer to this question the content of economic and social rights, and thereafter civil and political rights will be outlined, followed by an inquiry of what should really be considered as rights. Finally, the arguments against economic and social rights as real rights is presented and scrutinized.This paper will conclude that the stated difference between the above-mentioned sets of rights is illusory and that the right not to suffer from poverty ought to have the same status as civil and political rights..
Jämställdhetsarbete på en akademisk institution, från ord till handling
The essay discusses how to look at a equality plan of a academic department experiences the, gender equality in general and how power is portrayed from a gender perspective in the academic department. Through the use of qualitative interviews and a short survey the results have shown that few of the staff members have knowledge about the equality plan and few are familiar with its contents. Furthermore results show that the academic department is run hierarchyilly and that both vertical and horizontal gender segregation exists.The climate at the academic department is characterized by the will to work with gender equality but so far there have only been few exercised or planned efforts to do so. The gap between theory and practise is wide, the will to be seen as an equal academic department concerning equality of men and women seems important. The conscious or unconscious strategy of covering up the real gender equality seems to be done by focusing on the numerical equality..
HAVECA-modellen : En metod för att fortlöpande säkra ett internt nätverk mot tredjepart
This thesis will address a problem concerning availability of information systems at an enterprise within the financial sector and its external suppliers, so called trusted third party. The information system resides on the internal network of the enterprise and must be available to both employees of the enterprise and the trusted third party simultaneously. This contradicts the company policy which disallows third parties access to the internal network. The HAVECA-model introduced in this thesis provides a framework of methods, each solving a sub problem identified in the model. The identified methods are hardening, verification, control and assurance, together supplying a method for continuously securing the internal network against a trusted third party.
Att digitalisera kyrkliga handlingar
With this study we aim to learn more about the relationship between digitalization and the swedish church. We have interviewed two priests and two other persons ? one who got married about five years ago, and one who, at the time of writing, is getting married in a few weeks. In addition to the interviews we found some earlier research that were relevant to us, which we read and compared to the empirics we got from the interviews. In our study we have taken qualitative research into practice since we want our interviewees to really share their points of view on the organisation?s usage of digital media.
En komparativ litteraturstudie av olika termkällor för query expansion
The purpose of this thesis is to make a comparative literary study of ten laboratory experiments with different kind of sources for query expansion terms. The experiments are grouped according to categories of term sources, which are: search results, collection dependent knowledge structures, collection independent knowledge structures and one that combines the two last mentioned sources into one. To enable a comparison all other variables were held as constant as possible. There is the improvement measured in mean average precision, which is used to measure the various sources potential. The result from the study shows a strong connection between the kind of source for the expansion term and improvement of the result.
Den virtuella mötesplatsen : Om de ungas användning av datorer och Internet i vardagen
The purpose of this study was to illustrate how children of the "digital generation" used their computers in their everyday practice. The important in the study was children's perspective on computers interactions and communications in a digital arena.An essential item about understanding children's way to think about computers was to let children themselves speak by taking part in the study, because children's voices are seldom heard in public. The empirical material used was interviews with sex children between 13 and 15 years old. My method was qualitative.The main results showed that social relations are very important for children. The Internet gives children access to an arena where they are able to make new contacts with others as well as transcend their biological as their physical identity.An important accepts for the children in the study was the option to be anonymous.
AKK - Alternativ och Kompletterande Kommunikation : AKK som stöd i den dagliga förskoleverksamheten
This study was built on the concept of Emotional Intelligence (EI) as an ability with four branches, to effectively: (1) perceive (2) reason (3) understand and (4) manage emotions. By closely studying the four processes of EI through eight semistructured interviews with psychologists, counselors, CBT-therapists and psychotherapists, a study of participants' stories from real practice was done and then analyzed and interpreted. The purpose of this study was to get the participants to describe and put words on practical experiences that occur with clients that correspond to the four domains that define the concept of EI according to Mayer et al. (2008) and find out about if their way of "doing" EI gets trained and developed after several years of professional activity. The results shows that the practitioners used all four branches of EI in dialog with the client, both intra- and interpersonal.
