The Library of Uppsala University has decided to change their classification system from the Swedish SAB system to the American Dewey Decimal Classification. One of the main reasons for this decison was that Kungliga biblioteket also has made an exchange between these systems. Due to that, the national bibliography of Sweden classifies Swedish documents according to Dewey Decimal Classification and the SAB system is no longer maintained. A transition to Dewey Decimal Classification will enable Swedish librarians to import foreign catalouge posts and classification codes and will provide them with a common standard between their libraries and other libraries due to the use of the same international classification system. It is disputed whether the Dewey Decimal Classification is equally suitable for all subjects.

Automatiserad service är ett växande område där olika produkter och tjänster erbjuds genom kiosk- automater. Att använda den här typen av system är inget nytt, det har använts på flygplatser en lång tid för att avlasta personal, eektivisera och spara kostnader samt göra det smidigare för kunden att resa. Skillnaden är att det har börjat anammas av flera typer av företag och framförallt så är dessa system eektiva i situationer där man vill spara in pengar och låta kunden själv genomföra sina köp eller bokningar. Men för att dessa system ska vara kompletterande och inte öka utgifterna för företagen så krävs det att kiosk-tjänsterna har en fungerande och eektiv interaktionsdesign. Annars leder det till missnöjda kunder och ökade omkostnader för uppdateringar och underhåll.Vi har undersökt och utvärderat tre system för att se vilka brister som finns i deras användbarhet och hur detta påverkar efektiviteten.

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.

In the pilot plant at Hammarby Sjöstad, Sjöstadsverket, several new methods are tested in order to achieve a good use of resources. When a new technique is considered it is often the performance of the technique itself, under given conditions, that is evaluated. However, in order to evaluate the overall function the whole picture is needed. With a system analysis it becomes possible to make a comparison where all the positive aspects are put up against the negative ones, for the technique itself as well as its requirements. In this way the influence that minor components have on an entire system can be considered.This report presents a system analysis of an anaerobic membrane reactor (MBR) with a VSEP-membrane (Vibratory Shear Enhanced Process).

Quickmatch is a company that recruits students to other companies that need temporary workers. Today all administration is done by hand, which is very time demanding and therefore inefficient. Employees send assignment reports by e-mail about the working hours and breaks to the administration office. Since these reports are handled manually, there is a great need for an automated system that makes the company more scalable.The purpose of this work was to solve the defined problem, i. e.

During test flights SAAB uses the data acquisition system COMET 16. The part of the system that receives the signals from the sensors and converts them is called KSM 15. The purpose of this thesis is to develop a data acquisition module on stacked PC/104 modules with a lower production cost. Our work has been divided into one part about analog signal conditioning and a second part with digital filtering and memory management of the sampled data. The analog part, designed of regular components like instrument amplifiers, voltage references, operational amplifiers and multiplexers, adjusts the sensors signal levels for the ADC?s that converts the signals.

The thesis describes the following main question: Will the administrative labour during football tournaments be made easier with the help from a mobile web service or will it convey to unnecessary extra work? To be able to give a good and qualified answer to this question, the thesis will in the beginning describe how the technique for such a system might look like and also describe the existing administrative moments during a football tournament, this is too give the reader a deeper understanding for further reading. The thesis then goes on to describe a concrete system which is tested on three football tournaments. On the basis of the tests, interviews and through analysis of these the thesis will be able to answer our questions. The result which we present in the thesis have unfolded through testing of the system on three chosen football tournaments.

The main purpose of this C-essay is to answer the question: What have been the consequences and effects of the merit point system on language studies and the parties concerned (teachers, students and principals) during the school year of 2010/11?The merit point system is the result of a political decision and was implicated for the first time in the Swedish upper secondary school during the school year 2010/2011. Being a completely new phenomenon it is of great interest and importance to study its effects.The study in this essay also aims to verify, falsify or nullify two hypotheses very often referred to in the political discussions regarding the merit point system:The merit point system will replace affection and interest as main reasons for language studies in upper secondary school and cause a rectification amongst the students choices of additional courses.The merit point system will have a segregating effect upon society and make it harder for people to rise in society through education in the future.A verification of these hypotheses would imply the appearance of an increased rectification amongst students as well as an orientation towards an in the future more segregated society.The empiric material has been collected and examined with qualitative as well as quantitative methods (questionnaires and interviews) and belongs epistemologically to the phenomenological and hermeneutical traditions..

Rapporten undersöker om kontextberoende generering av träd är lämpligt att använda i dataspel. I arbetet presenteras ett system som möjliggör procedurell generering av träd som omgivningen kan påverka. De faktorer som inverkar på trädets grenstruktur är solljus, vind och gravitation. Projektet bidrar med en lösning till att minska utvecklingstiderna för dataspel genom att möjliggöra att trädmodeller algoritmiskt genereras i datorn istället för att de modelleras av en artist..

The dependency of continuous electricity supply is high in the Swedish society today, at the same time no one is willing to pay for a too costly or over dimensioned power distribution system. The owners of the distribution systems are the ones responsible for this balance act of maintaining a high quality of electricity delivery to customers at a reasonable cost.In this master thesis a limited part of the primary distribution system (10 kV), owned by Mälarenergi Elnät AB and located in the city centre of Västerås, was chosen for a deeper analysis of its reliability. Its ability to handle outages of system components (N-1 and N-2 contingency analysis) was investigated to find out potential weak spots and parts of the grid that showed signs of being overdimensioned.The results of the performed simulations showed that in 74 % of the studied N-1 contingencies cases, consisting of outages of a bus bar in a distribution substation, the system could handle this without causing outages in other parts of the grid. For the N-2 contingencies 61 % passed the test. It was also found that one of the two included high voltage substations could alone supply the investigated part of the grid.

Denna examensrapport redogör för hur man kan få en kortslutningsskyddadoch säker inkoppling av en DC-länk mellan två skiljda elektriska system.Rapporten bygger på hur en lastbil ska kunna få en större säkerhet för attbibehålla sina elektriska bromsar om tex ett av bromssystemen tappar sinordinarie matning.Lastbilens bromssystem består idag av två skiljda elektriska system med ett 24volts strömförsörjande batteri vardera. Det ingår två stycken elektriskabromsar i varje system. Om det tex blir fel på en av bromsarna och dennapåverkar ett av systemen vill man kunna koppla bort denna enskilda bromsmed sitt system. Man vill även kunna försörja den fungerande bromsen somsitter i samma system via en så kallad Axle Link. Denna strömmatningslänksitter mellan två hjulpar på samma axel.I denna studie undersöktes möjligheten att realisera en kortslutningsskyddadoch säker DC-överföring via en Axle Link, i första hand med diskretakomponenter.

Sheep production is the only animal production in Sweden that is increasing. Therefore,increasing knowledge of the production is of great interest. In order to run a viable sheepproduction, producers needs to be successful in the breeding of the animals and achievean economic surplus in the end. Lambs that are born healthy and vital have greaterconditions to perform high lamb weight gains and thus a successful production. Thereare many factors affect the survival, birth weight and early weight gain of the new bornlamb.

Failed system development projects are a common sight within the IT-industry. During the last ten years we have seen several more or less disastrous high profile projects being reported in the news. One aspect that might hold some of the responsibility for these failures is the fact that more organisations are knowledge intensive which makes their work processes difficult to capture in computer systems. How requirements engineering is handled becomes even more important in these cases, where processes are unpredictable and rely on individual judgement and knowledge. In this study we have examined the challenges of developing systems for knowledge intensive businesses through a method of qualitative case study of a university laboratory.
