Den demokratiska konsolideringen i delade samhällen - fallet Makedonien En studie om Makedoniens demokratiska utveckling efter den väpnade konflikten år 2001
The consociational democracy model in Macedonia, which came out from a warcrisis and a peace agreement from 2001, in addition, putting an end to the violent conflict, actually admits the division of the society along the ethnic lines. Paradoxically, there is an attempt to bridge the ethnic gap with this model. As a result, the consociational democracy model holds solutions that can be abused if somebody misuses its power and desires to disintegrate the country. The future development depends therefore on the moderate attitude of the citizens, and first and foremost, on the political elites and their commitment to the values of democracy and human rights instead of their nationalistic goals. Furthermore, thepresent democratic consolidation in Macedonia is established on the execution of the peace agreement and the improved effectiveness of the institutions.
Price adjustment and vacancies on theStockholm market ? Estimation of rent levelsdue to office-allocations
The Stockholm office market segment have for a long time been considered a safe havenwhen it comes to withstand negative turmoil in the form of rental compression due toeconomic fluctuation, especially in the CBD demographic. Recently however, a large numberof banks and institutions, amounting to some 200000 square meters, have decided to relocateto more peripheral locations with the aim of cost reductions on rent. This mass exodus isstudied with focus on rental dynamics as the result of increased vacancies. Other variables arestock changes and employment. The method is econometric combined with an interviewseries.
Frekvensreglering i det nordiska kraftsystemet
Svenska Kraftnät is (together with the other transmission system operators of the Nordic power system) responsible for keeping balance between the generated and demanded power in the Nordic power system. Spontaneous load variations and system disturbances, however, lead to power imbalance followed by frequency variations. The frequency deviations can be limited to an acceptable level by the spinning reserve, mainly by hydro power control. But there are also other system properties which have a great influence on the frequency and system stability. The frequency and voltage dependence of the loads have a direct influence on the power balance.
Någonting mystiskt händer i Sjumilaskogen: En kulturpolitisk analys av TV-reklam riktad till barn på TV 4 och Kanal 5
The aim of this Masters thesis is to review Swedens unique law against TV-commercials intended for children under twelve years old. The law has to be abided by TV 4, but not by Kanal 5, so the aim is also to compare TV 4 and Kanal 5 and to see in what different ways commercials are shaped in the two channels. The cultural policy analysis is based on our aim and problem. We have also had the terms semiotic and intermediality in mind together with a model made by the researcher in semiotics Roman Jakobson. The model consists of six different communicative functions.
3D-modellering i AutoCAD -att skapa en digital huskonstruktion
3D-modelling in AutoCAD This thesis is done in cooperation with LB-Hus in Bromölla, and have aimed to establish a digital AutoCAD model of one of the company?s house types and to find out what opportunities there are to do visualisations in the form of images directly from the programme. Modeling has been carried out so that the very construction of the house is included. Interiors and installations, with the exception of the ventilation system, have been left out in the model. The model has been created with solid models after a comparative study made between solid models and surface models to find out which option in this case was the easiest to handle and took up the least space.
Utvärdering av Capcals förmåga att beräkna framkomlighet
Performance of an intersection affects the total travel time in a traffic network. An intersection with good performance can easily be described by its contribution to lower travel time than in a comparable intersection. The travel time is of importance in the cost calculations when a specific intersection is to be chosen and designed. It is important to be able to make correct and precise performance calculations so that the cost calculations will not be incorrect. For that purpose the software Capcal, which is a traffic model for intersection analysis on performance, is used in Sweden.
Rocchio, Ide, Okapi och BIM : En komparativ studie av fyra metoder för relevance feedback
This thesis compares four relevance feedback methods. The Rocchio and Ide dec-hi algorithms for the vector space model and the binary independence model and Okapi BM25 within the probabilistic framework. This is done in a custom-made Information Retrieval system utilizing a collection containing 131 896 LA-Times articles which is part of the TREC ad-hoc collection. The methods are compared on two grounds, using only the relevance information from the 20 highest ranked documents from an initial search and also by using all available relevance information. Although a significant effect of choice of method could be found on the first ground, post-hoc analysis could not determine any statistically significant differences between the methods where Rocchio, Ide dec-hi and Okapi BM25 performed equivalent.
Modellbaserad drivlinereglering
A cars powertrain consists of everything that is needed for its propulsion. The components in the driveline that transfer the power from the engine to the driven wheels are not absolutely stiff, hence they will wind up due to the torque and act as torsion springs. If you suddenly demand a bigger torque by stepping on the accelerator pedal, a so called tip in manoeuvre, and that torque is acquired from the engine as quickly as possible, the driveline will not be able to transfer that fast torque change due to its weakness and as a result it will start to oscillate. These oscillations will be transferred to the driven wheels and make the car to accelerate jerkily which will be experienced as uncomfortable by the passengers. Furthermore, there is a backlash in the driveline that will make the weakness in the driveline even more excited than it should have been if the backlash did not existed.To avoid too big problems with these oscillations there is a control system that controls the demanded torque.
Termomekanisk utmattning av Sanicro 25 : Materialmodellering med finita elementmetoden
The report aims to describe the austenitic stainless steel Sanicro 25 from a thermomechanical point of view. The thermal and mechanical properties of the material make it suitable for use in coal ? and thermal power plants. By the use of Sanicro 25 it would be possible to bring the efficiency of these plants up while bringing the carbon emissions down.A material model is created from material testing and validated through simulation in the finite element software Abaqus. The model that has been derived describes the material behavior during loading and stress relaxation for the first cycle in a thermomechanical fatigue test well.
Kreditklassning av aktiebolag i Sverige, en logistisk regression
Predicting corporate failure is an increasingly important topic in the world of economics today. This paper, with the help of the credit ranking company Syna AB, aims to investigate a few different statistic strategies to do just that. This task is accomplished by using a data material of 250 000 Swedish companies divided into two subsamples. The first sample is used to develop the model and the second as a validation sample. The model developing sample holds 160 000 companies divided into five different subgroups based on size and age.
Utveckling av lastmodell för Uppsala fjärrvärmenät
The aim of this study was to develop a load prognosis model for Uppsala district heating system to be used as a tool for heat production optimization. The methodwas to build three models for the different customer types; housing, industry andoffices and then scale them for the total system using data from Uppsala districtheating system. The heat load consists of two parts, one that is temperaturedependent and one that is dependent of the social behavior of the customers. Thetemperature part was modelled with an ARX model using an outdoor temperatureprognosis as input signal. The social behavior part was modelled using the mean ofthe social behavior from some days before and additionally by distinguishing betweenweekdays and weekends.
Förskollärares erfarenheter av särskilt stöd i förskolan
Much of the everyday work of teachers in pre-schools, schools and youth centers is based on experience. This study is a qualitative interview study intended to make visible the experiences of pre-school teachers in situations when children are considered to be in need of special support. I have looked at pre-school teachers? descriptions of the kinds of situations in which a child is estimated to be in need of special support, what teachers look for in a child to identify it as a child in need of special support in a specific situation, and how the teachers define special support. Both this study and previous research show that children?s estimated need of support depends on the situation and context the child is in. The pre-school teachers in this study identify common situations where children are estimated to be in need of special support, namely: in interaction with others, in structured situations, during changes of activities and during free play.
Kunskapsteori och kunskapsorganisation: En diskursanalys
This Masters thesis concerns epistemology in Knowledge Organization KO, as a field of study in Library and Information Science LIS. Using a theoretical model by Birger Hjørland and foucauldian discourse analysis as springboards, this study analyses three epistemological discourses in the practice of KO. The aim of the study is to show how these discourses are constituted and demarcated in relation to KO, as well as to examine how they fit into Hjørlands model. A brief historical outline of some epistemological trends in LIS is sketched, as well as examples of how different epistemological schools influence different parts of KO, e.g. information retrieval, indexing- and classification theory.
Modellering av reserv- och nödkraftsystem i JAS 39 Gripen
Simulation is a vital tool during development of JAS 39 Gripen, since money and time can be saved.The Auxiliary and Emergency Power System, AEPS, is a subsystem of the secondary power system in Gripen. It has the function of providing the aircraft with electrical and hydraulical power before activation and after deactivation of the main engine. The system also functions as backup in case of a safety critical problem in the main power supply system. The system basically consists of a control unit and an auxiliary gearbox. The gearbox is driven by an air turbine.
Belting - en studie av hur en sångteknik beskrivs och används
Uppsatsens syfte var att utforska och definiera belting, den kontroversiella sångtekniken som kommit att bli allt mer vanlig och använd bland sångare, som ett resultat av ett ökat intresse och flöde av populärmusik i vårt samhälle. Syftet var också att studera hur denna teknik används av sångpedagoger i deras arbete. Denna kvalitativa undersökning är baserad på litteraturstudier inom röstfysiologi och röstens funktion, och specifika teorier angående belting. Den grundar sig även på intervjuer av sångpedagoger som använder belting i sitt vardagliga arbete, både som pedagoger och som sångare. Resultaten visar att belting kan ses som en röstfunktion eller som en utvidgning av det låga registret, eller som en blandning av båda.
