Det är dit man går om man ska söka information. Skolbibliotekets roll i gymnasieelevers informationssökning
The aim of this thesis is to examine how high school students use their school library for their information-seeking. The theoretical framework is based on Louise Limbergs three categories of students views on information-seeking and Andrew Large and Jamshid Beheshtis three categories of students choice of information systems. Qualitative interviews were used and seven high school students were interviewed. The empirical material was compared and divided into 9 categories. The results show that the students see the school library as a place where they can search for information, but its also considered to be a good place to hang out between lessons to study or to meet friends.
Kungliga bibliotekets klassifikationssystem över den svenska samlingen år 1887
We have carried out a study of a classification system for the Swedish collection at The Royal Library in Stockholm from 1887. It was printed in 50 copies. The constructor, Bernhard Lundstedt, and his colleagues used it as guidance in lack of a catalogue. We regard it a local classification system. Little research has been done on old classification systems, but Francis Miksa points out the importance of examining them.
Bilden av kvinnan i Library of Congress Classification En genusstudie av Library of Congress Classifications första och senaste upplaga
I have done a comparative gender study of Library of Congress Classification from 1900 and 2001. I have also used a hermeneutic method and ideological critics to find out what picture of women the both systems shows. In my comparative study of the both systems I have found low update of classes which relates to women in the new classification system. Men seem to be a norm in the system, because men are not defined in classes related to both men and women. But many classes related to women are named Women as and Women in The study also shows that women are more related to subjects about family and marriage than men are.
Implementering av mjukvarubaserat PLC-system för reglering av magnetiseringen av en synkrongenerator
In order to reduce the price for, and improve the performance of automatic control systems for magnetization of synchronus generators, the possibilities of using a PC based software PLC system, Programmable Logic Controller, has been investigated. The result is a system based on the CoDeSys software PLC with runtime environment from 3S-Software, communicating with external units via Modbus fieldbus. System price is reduced from ?5000 to ?2000 and system processing speed is reduced from 10 ms for a Siemens S7 PLC to 4 ms with the CoDeSys PLC system though unsolved problems with runtime seizure caused by improper settings in the PC BIOS..
Effekter av ett informationsintensivt material- och produktionsstyrningssystem
We were assigned to do this master thesis by Husqvarna AB who at the time for this thesis just had implemented a new material and production planning system called Replenishment system. Husqvarna AB wanted us to examine the effects of their new planning system to see if it was profitable or not. Husqvarna AB had for a time considered their delivery and supplier service to bee their biggest problem and they wanted to solve this problem by improving the communication with all involved actors in the logistic chain, which they hoped would result in a better mix of products in their warehouses. The aim of this report was therefor to analyze eventual effects for Husqvarna AB when changing from a traditional material- and production planing system to a more information intensive one. The result of this report showed effects on decreasing administrational routines and improved flexibility and lead-times.
Säkerhetsanalys av Windos Server 2008 i militära system
This analysis recommends not to use Windows Server 2008 without properevaluation in any system containing classified information. The reasons are too lowassurance and too weak authentication. If Windows Server 2008 is to be used itshould be supplemented with a stronger authentication mechanism. The installationshould preferably be of Server Core type and the server should be maximallyhardened..
Miljöbron - Går det att göra ett databassystem med begränsade resurser?
Miljöbron is a non-profit organization; their main purpose is to merge companies and students into different environmental projects. The projects can be an assignment, practical vocational training or degree thesis. Miljöbron is expanding and the demand from students and companies is rapidly growing. Because of the expansion, a large amount of information needs to be stored and managed in a structured database. Also the need of a interface that is structured and easy to use when managing information and Miljöbron?s statistics, for Miljöbron?s staff.
Levbart transportsystem i Uppsala
In this thesis a transport system is sought after thatif realised in the city of Uppsala could provide bothwell-being to all its inhabitants and sustainability,here jointly refered to as liveability. It is found thatthe car dominated transport system that is inoperation today provides two fundamental values,namely accessibility in both time and space, whichsets it apart from other transport solutions. Thesetwo values are of immense importance for theliveability in our modern world. On the other handthe car dominated system decreases the liveabilityof Uppsala in several different ways. Some of theseproblems, it is argued, could be solved within thecar system, through the adoption of moreenvironmentally friendly cars etc., but otherproblems are inherent in the car system and willremain no matter what changes are made.
En studie om fastighetstaxeringssystem : -Vad kan Sverige lära av England och Wales
According to the client, land survey of Sweden, there is no current information regarding other well developed property tax systems. This information is necessary in order to analyze the effectiveness and develop the Swedish system. The purpose of this study is to contribute with improvement proposals to the development of the Swedish property tax system through a survey of the English and Welsh property tax system.Methods used are: (1) a literature review where the English and Welsh valuation methodology and organization regarding property taxation is studied; (2) an interview with the client at the land survey of Sweden regarding existing problems with the Swedish property tax system; (3) An interview with a contact person of the Valuation Office Agency regarding the English and Welsh property tax system.In England and Wales there are two different property taxes for municipals, Council Tax and Rating. All domestic properties are included in Council Tax and commercial properties or part of commercial properties is included in Rating. Council Tax is based on the properties market value and Rating is based on the commercial property or part of the properties current rental value.
Ett vårdinformationssystem i vårdens frontlinje : En fallstudie om Cambio Cosmic på en vårdcentral i Landstinget Kronoberg
In healthcare there is a rapid development towards introducing and implementing a wide range of information technology (IT) to aim for higher quality and more effective care. A common health information system (Cambio Cosmic) has been implemented in Landstinget Kronoberg. Clinical microsystems are the frontline units where staff and pa-tient meet. When the conditions in the microsystems are changed, it is interesting to de-scribe and analyse the consequences.The purpose of this study is to describe how health care staff uses a health information sys-tem and how they experience its functionality in their patient work. Initially, a literature re-view about the use of health information system was undertaken, followed by a qualitative case study based on interviews about how healthcare staff describes their reality.
Hjälpkraftsystem med två lågspänningsnivåer
Because of increasing demand of power on Malmbanan the capacity of the existing wires which supply the trains must be increased. This increases the stress on the existing poles and for this reason the system for supplying the loads along the railway is to be removed from the poles and be replaced by some other system. This thesis is a study on a two-level low voltage (1 kV and 0.4 kV) electrical system with the aim to investigate if it can be an alternative to the system used today taking into account the voltages, fault currents and costs.In this thesis the following tasks have been performed:? Gathering of data? Description of basic theory? Loadow and fault current calculations of the system with MATLAB? Life Cycle Cost estimate of the system? Analysis and conclusions from the resultsThe results show that the new system can be an alternative to replace today's system. The simulations and calculations show that the voltage drop is at an acceptable level and that the fault currents are large enough to supply a safe disconnection if a fault occurs at the far end of the system..

Museum på webben - en undersökning om användbarhet och åtkomst
The aim of this thesis is to describe and evaluate the usability of two Swedish systems, Sofie and Carlotta, which are used to organize and present data regarding museum objects on the web. This thesis also presents how objects are described and made accessible to the public in the two systems. To evaluate the usability, a heuristic method combined with Systematic Usability Evaluation has been used. The description and accessibility of object representations in the systems are evaluated using indexing and classification theories from the field of Library and Information Science. Additional theoretical background that has been used is how users search and browse information systems.
Ett verktyg för konstruktion av ontologier från text
With the growth of information stored over Internet, especially in the biological field, and with discoveries being made daily in this domain, scientists are faced with an overwhelming amount of articles. Reading all published articles is a tedious and time-consuming process. Therefore a way to summarise the information in the articles is needed. A solution is the derivation of an ontology representing the knowledge enclosed in the set of articles and allowing to browse through them. In this thesis we present the tool Ontolo, which allows to build an initial ontology of a domain by inserting a set of articles related to that domain in the system.
Felhantering vid informationsutbyte mellan IT-system
Problemet med hantering av fel vid informationsutbyte mellan system hos stora företag med komplex IT-arkitektur är bakgrunden till varför denna rapport har skrivits. Det primära företaget i denna studie har varit Sandvik AB.Typiska fel som kan uppstå i sådana sammanhang är så kallade logiska fel. Definitionen av ett logiskt fel är ett fel som påverkar processens funktionalitet vid utbyte av information mellan två eller flera system. Exempel på sådana fel är att ett visst system behöver en viss speciell information eller har vissa regler uppsatta för att kunna ta emot information från ett annat system. När det hänvisas till tekniska fel, så avses fel som kan uppstå i den tekniska infrastukturen.Problemet med logiska fel finner man mest i distribuerade system och i SOA-arkitektur där det finns en anledning till detta på grund av dess uppbyggnad och lösa kopplingar mellan system.
