The Swedish energy companies have several different systems for data collection of the energy consumption of their clients. Often computerized remote meter readers are put in practice in order to register the energy consumption of large companies. The majority of household clients, however, are read off by the assistance of manual methods. Household power consumption is read off once a year. As a result, these clients are not debited for their actual consumption; their invoices during the year are the result of estimations.

Many traffic incidents are due to the driver?s lack of attention, resulting in dangerous lane departures, either sliding off theroad or into the oppose lane. These kinds of incidents often have serious outcomes, which has led to much effort being concentrated on preventing or lessening the damages when the incident is already a fact, for example by installing safety belts and air bags. These measures may be considered to be acts of so-called passive safety. Active safety on the other hand, means that the safety systems intervene before the incidents have occurred.

Allt fler verksamheter väljer att investera i IT lösningar, med avsikt att skapa konkurrensfördelar gentemot organisationer i samma bransch. ERP system är en av dessa IT lösningar, och det har framkommit att dessa system inte alltid fungerar på ett tillfredsställande sätt. Därför är dessa system att betrakta som mindre dugliga ur ett användbarhetsperspektiv. Avsikten är att utveckla vår modell (TTF/A) som studerar hur en matchning mellan systemkaraktäristiska drag och karaktäristiska drag hos arbetsuppgifter påverkar systemets användbarhet. Modellen betraktar även hur erfarenhet av teknologianvändning och erfarenhet av att utföra arbetsuppgiften påverkar matchningen.

During the later parts of the 20th century there occurred several changes to the Swedish public sector. These changes aimed to effectivize and decentralize the governance model in the public sector. One of these changes was the municipalization of the school system, put forward and proposed by the social democratic government in the late 1980s and early 1990s. This study aims to examine and compare that times different parliamentary parties' opinions on the municipalization of the school system. The source material consists of government bills, and in direct relation to the municipalization of the school system.

The purpose of this thesis is to examine and analyze why, in the case of Afghanistan, the government chose to establish a highly centralized political system, when from a democratic standpoint a less centralized system would be preferable.The time period that is examined span from 2001 when the so-called Bonn-Accord was signed, to the parliamentary elections held in 2005, a period often referred to as the Bonn-process.The theoretical framework examines both the complex relations between federalism and democracy, as well as the relation between federalism and the role of existent ethnic minorities. The theoretical framework is then used in order to explain why it would be problematic to create a federal system in Afghanistan under the present circumstances.The conclusions that can be drawn are the following: In case of the republic Afghanistan the creation and implementation of a highly centralized political system was the only possible way for the government to be able to cope and practically deal with the problems of existent ethnic antagonism and regional warlords in order to create a stable political situation in the country..

Sammandrag Information flödar genom samtidens organisationer och behöver systematiskt kontrolleras. Genom att implementera Enterprise Resource Planning Systems, även kallat ERP-system, kan företag enklare samla upp, strukturera och utnyttja all denna flödande information i ett och samma informationssystem. Majoriteten av alla företag misslyckas dock att fullständigt integrera ERP-systemet med sina vardagliga rutiner. Tidigare forskning tyder på att den utbildning slutanvändarna får och ett kontinuerligt ifrågasättande av organisationens värderingar, även kallat double-loop learning (DLL), påverkar organisationens möjlighet till en fullständig integration. Genom en kvalitativ flerfallsstudie på olika företag inom detaljhandeln, alla användare av samma ERP-system, har denna studie undersökt vilken roll utbildningsfasen spelar för att DLL ska uppstå vid en ERP-implementation.

The aim of this study was to examine how the interviewed teachers in one school observe their view of gender and equality regarding the educational system.  Accordingly, I would like to present my intention with this study, also be to analyze how the interviewed teachers way of working with matters of gender and equality, carry out as a portrait of their values considering the distribution in terms of gender. The research questions are the following: What is the teachers view on the concepts of equality and gender in school?How do different teachers talk about their way of working in relation to gender and equality in school?How is boys and girls images presented in the teachers descriptions in their discussion about gender and equality?This study is based on a fundamental qualitative method, where a handful number of teacher?s from one school were interviewed in order to obtain information and data for the examination. The interviews were analyzed and discussed in association to earlier research in aspiration to study different writer?s theories about the conception of gender and equality.

In this project the focus has been on the system for recombination at Oskarshamn 2. The recombining systems have on several occasions switched paths due to low pressure before the last ejector that?s feeding the recombiner. Of the mentioned reason, events and several measuring points have been analyzed in this report since the installation of the recombining systems.In order to prove theories and demonstrate what may be the cause of this problem, we used heat balance calculations by the program Probera. Using the program, we can demonstrate that the catalytic process does not reach the desired temperature with the amount of combustible substance.

The interest in small-scale electricity in Sweden has increased strongly in recent years. The interest is noticeable both among politicians to increase the share of renewables in the energy mix, and among electricity consumers to partially replace purchased electricity with self-produced. This has resulted in a significant increase of electricity production in low voltage grids in recent years, and the trend appears to continue in the coming years. The majority of the new production plants are solar cells, followed by wind turbines, and it is also in these the greatest efforts are made in this paper.Distributed generation is often seen as something positive since it will contribute to reduced transmission losses and reduced voltage drop in the networks, and that it increases the share of electricity from renewable sources. In cases where the grids are not strong enough, or in other ways not adapted to manage the installed production, power quality may be adversely affected.

This report is the result of a thesis conducted at the consulting firm Bjerking AB andis the final part of the Bachelor Programme in Construction Engineering at Universityof Uppsala. The work aims to investigate the costs and how the choice of ventilationsystem affects building projects during a long-term period. This report covers costssuch as investment, maintenance and energy but also how they affect residents andbuilders. Building regulations for energy consumption are expected to be tougher;therefore a comparison of two different heat recovery ventilation systems(HRV-system) was made. One system is based on a centrally placed unit that coversthe whole buildings ventilation through vertical shafts.

This report examines some common or otherwise interestingnon-cryptographic hash functions with respect to the number of collisions when used in hash tables for different types of hashkeys. The report answers which of the examined hash functions can be seen as the best performing for the chosen hashkeys. To compare the different hash functions, an experiment which studies avalanche effect behaviour is carried out. The experiments also calculate the fraction of colliding hashkeys, and the distribution of hashkeys in hash tables is studied using Karl Pearson?schi-squared test.

AbstractIn the fall of 2003 a project was started in the Swedish building sector that is called BASTA (the building sectors’ termination of especially harmful substances). The project is operated by the building companies NCC, Skanska, PEAB and JM, the Swedish Building Industry and the Swedish Environmental Institute IVL. The purpose of the project is to create a common environmental assessment system for the entire building industry and with the help of this system phase out the use of especially harmful properties from building products.In a large sense BASTA works like this; On the BASTA web site there is a database, to which a supplier can register the company and the company’s products. Only those products with a substance content that fulfil the demands of the BASTA system, is to be registered. As it is the supplier himself that carries out the registration of the company and the company’s products to the system, the BASTA-organisation annually controls that the companies that are registered in the database, fulfils BASTA’s demands.Since NCC is one of the companies that operates BASTA, BASTA is probably going to be the environmental assessment system that is recommended for the company in the future.
