????Att lösa reglertekniska problem med Modelica
Modelica is a multi-domain and equation-based modeling language. Modelica is based on object-oriented principles and non-causal modeling. The language is constructed to facilitate reuse and decompose models. The models and the modellibrary can modified to design a new nonlinear components.Object-oriented modeling is an excellent way to analyze and study large complex heterogeneous physical systems. The object-oriented modeling approach build on reusing and decomposition of models and non-causal modeling.Modeling physical systems often leads to a DAE system with index 2 or 3.
Klassifikation av litteratur om film och TV ? En komparativ studie av Klassifikationssystem för svenska bibliotek (SAB) och FIAF Classification scheme for literature on film and television
The aim of this thesis is to compare two different classification schemes with each other and see what the differences and similarities are when classifying literature concerning film and television. One of the schemes is of general kind, Klassifikationssystem för svenska bibliotek (SAB) and the other is a special system, FIAF Classification scheme for literature on film and television. The focus of the examination is on comparing the structure, contents and division of firstly the main classes and secondly on comparing the notation and the auxiliary tables in the schemes. The theoretical framework of the comparison is based upon theory of classification but the conclusions drawn are though mostly of a more subjective character. In addition to the comparison itself interviews have been made with four libraries, two with experiences of SAB and two with experiences of FIAF.
En jämförande studie mellan tre selektiva agarplattors förmåga att detektera ?-laktamas producerande bakterier
Betalaktamaser med utvidgat spektrum så kallade Extended Spectrum Beta-Lactamase (ESBL) är enzymer som produceras av bakterier och som har en avgörande roll ur kliniskt perspektiv då de blir resistenta mot de flesta antibiotika vilket leder till begränsade behandlingsalternativ. För att selektera fram dessa bakterier användes kromogena agarplattor vid odling, vilka selekterade bort jästsvampar och grampositiva bakterier och underlättar detektionen av ESBL-positiva stammar. Syftet med studien var att jämföra tre olika selektiva agarplattor CHROMagar ESBL, ChromID ESBL och CHROMagar C3GR genom att utvärdera deras specificitet och sensitivitet. Totalt användes 130 olika patientprover från feces, blod, sår och urin, vilka valdes ut slumpmässigt ur den rutinmässiga diagnostiken. Proverna odlades på de tre agarplattor.
Ämnessökningar med kontrollerad vokabulär och naturligt språk: en jämförande studie med felanalys.
The aim of this thesis is to compare the effectivity of using a natural language and a controlled vocabulary when performing subject searches in the bibliographic database LISA Library and Information Science Abstracts. 20 topics were created and for each topic two searches were made, one by using a query formulated with natural language directed to the abstract field and the other one by using a query formulated with descriptors from the thesaurus in LISA directed to the descriptor field. The average relative recall amounted to 64,8% for the AB-queries and 54% for the DE-queries. Failure analysis showed that the majority of the relevant documents not retrieved by AB-queries could have been retrieved with other query terms, such as synonyms. In a natural language there are many different ways of expressing a topic, and this tends to have a negative effect on retrieval effectivity.

Klassifikationssystem för en medicinhistorisk samling en jämförande studie av SAB och NLM
This thesis deals with classification of the subject field history of medicine. The two classification systems SAB and NLM are compared in order to find out which one is the most adequate to organize a small collection of history of medicine. SAB and NLM are the two most commonly used classification systems in medical libraries in Sweden today. NLM classification system specializes in medicine and SAB is a universal classification system. Our purpose with this study is to find out the pros and cons of each system, whether the systems treat the subject history of medicine in a satisfactory way and what kind of classification system that is better for this assignment, a specific one or a general one.
Thymidinkinas 1 som tumörmarkör vid juvertumörer hos tik :
Determination of serum thymidine kinase 1 (TK-1) activity is used as a tumour
marker in both human and veterinary medicine. TK-1 is an intracellular enzyme
involved in a salvage pathway of DNA synthesis. The expression of TK-1 is cell
cycle dependent and the activity increases markedly after the G1 to S transition in
the cell cycle and then declines rapidly in G2. The pronounced proliferative
activity in tumour cells result in a higher TK-1 enzyme activity within the cell.
The fact that the increased TK-1 activity can be measured in serum makes TK-1 a
useful marker in diagnostics of neoplastic diseases and it provides information
regarding prognosis and treatment effectiveness. In human medicine a radioactive
based test is used to determine the TK-1 serum activity.

Är det svårt att hitta i en mobitelefonmanual? : En kvalitativ fallstudie om informationssökning och användbarhet
This master thesis states the following questions: Is it easy or difficult to retrive information from a mobile phone manual? How can the search process be described among user for a mobile phone manual? What similarities and differeces can be identified between users? Arhe there any variables that affect search performance such as reading skills or technical domain knowledge? Eight mobile phone users participated in an empirical observation and the scope was to find information in a paper version of a mobile phone manual according to given tasks. The results shows that some users has problems to retrieve information due to that the correct page in the mobile phone manual could not be located. The results show that the user is using several search strategies, for example the table of contents and the index, when trying to locate information. The results also revel that the user initiates multiple search steps before the correct information can be located.
Internetbaserade insamling och behandling av data
AbstractAim of this project was to analyse signals and try to localize the position of source of sound. It is donewith three microphones which have 90 degrees angle to each other. Each microphone detects one partof the sound wave. The microphones are connected toan ADC which turns signals from analogue todigital shape. After that the three signals are transformed to a computer.
Axess och feminism : En kritisk granskning blir kritiskt granskad
This essay is about a debate concerning the magazine Axess, feminism and antifeminism - in relation to a issue of Axess called To a new feminism. The theoretical foundation of this essay is Pierre Bourdieu and his field theories. The battles taking place in this particular field concerns the positioning of feminism and antifeminism in the way we culturally interpret these in our society. The essay shows that the magazine Axess (at least in the first edition of 2012) links feminism with a very prominent symbolic capital in a culture context. This discussion can at times seem confusing, and this is probably due to the fact that Bourdieus symbolic capital can be a very abstract concept. The journalist and author Maria Sveland writes about the development of a culture moving towards accepting antifeminism (and also xenophobia). She expresses the opinion that this, to a high degree, is due to actors in the culture domain with a big amount of trust in the public eye has moved towards expressing anti-feministic (and xenophobic) views.
URLen som förbindelselänk: en utvärdering av URLers pålitlighet som åtkomstmetod mellan webbresurs och bibliografisk post i LIBRIS och NetSök
The aim of this masters thesis is to study the reliability of the URL as the link between a bibliographic record and a web resource. The Swedish catalogue services LIBRIS and NetSök have been evaluated on three different occasions, to study how these services have succeeded in giving access to web resources by using URLs. Because URLs are changeable, we have tried to find out common characteristics of the URLs in broken links. To accomplish this study we have used a quantitative approach and evaluated five percent of the web resources in the catalogues using a random selection. We have also used documentation relevant for our study, among other things to illustrate previous studies of the nature of web resources and alternative solutions to URLs as access points to web resources.

Dynamisk kunskapsorganisation: teoretisk ansats och implementering
Knowledge organization is perceived as a central, constituting activity defining the notion of libraries. Critique calling for a new theoretical foundation voiced by active researchers within library and information science concerning the current knowledge organization has been utilized as a point of departure. Specifications concerning a new theoretical foundation implied by these critiques are considered within this thesis and theory found in The Order of Things by Michel Foucault proposed as an alternative theory for understanding knowledge organization as a human science where meaning, value and representation, by which the ordering of things is possible, is acknowledged as a result of human activity and history. Thus meaning, value and representation must be perceived as dynamic. An example of implementation of the proposed theory has been achieved by the use of bibliometrics.
