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.

Utmattningsberäkning av hydraulikkopplingar : Metoder och beräkningar gällande utmattningsteorier

The purpose of this thesis is to investigate the fatigue life of two components in different hydraulic quick couplings. The crack which initiates the fatigue Failure usually occurs in the bottom of one of the threads. Thus, the threads in the coupling are carefully investigated. A few different approaches for determining the fatigue life are studied for each component. CAD (Computer Aided Design) models for both components are created and analyzed with FEM (Finite Element Method).

Aortic Body Tumors in Dogs

The purpose of this essay was to review the literature and describe the patophysiology, diagnosis, microscopic and macroscopic appearance of aortic body tumors in dogs. The tumors originate from the chemoreceptor organs situated at the base of the heart. The chemoreceptor organs are neuroendocrine cells responsible for surveillance of changes in e.g. the blood pH. Aortic body tumors are rare and represent 7 % of the total cases of primary cardiac tumors in canines.

Hydroperikard hos katt : patofysiologi, diagnos och behandling

Hydropericardium or pericardial effusion (PE) is the accumulation of fluid in the pericardial sac and is often secondary to pericardial diseases or diseases related to the heart. It is unusual with clinically relevant pericardial diseases in cats but pericardial effusion is the most common one. Since PE causes serious symptoms and may lead to death it is important with a quick diagnosis and treatment. PE can be acute and cause cardiac tamponade, which gives severe clinical signs. Cardiac tamponade needs to be treated immediately or else the cat will die from cardiogenic chock. More common is chronic PE where the fluid accumulates during a longer period of time and the pericardial sac stretches.

Representativa testnät försvenska eldistributionsnät

This project was started within the Market-Design programme of Elforsk, with the aim of developing representative test systems of Swedish distribution networks. Using such test systems as a basis for reliability and customer interruption cost calculations makes it feasible to analyse the network tariff regulation of Swedish power  istribution companies. In particular, it enables studies of the incentives for companies to invest in system reliability. Until now, the available test systems are either not representative of Swedish conditions, or too small in scale and limited in function.Within this project we have created two test systems. In order to represent the diversity of actual Swedish distribution networks, we have created one test system for urban environments and another for rural environments.

Trovärdighetsbedömningen av muntliga utsagor i brottmålsprocessen

In some criminal cases, the only existing evidence is the verbal statement of a witness or the plaintiff. The typical example is an alleged rape where victim and perpetrator have had some kind of relation, and their records of the incident differ. In these cases, the assessment of the value of the evidence drawn from the plaintiff's story is of crucial importance. On the one hand, a false positive judgment means that a person is wrongly convicted, on the other hand, a Failure to correctly identify a truthful claim of rape means that a victim of a severe crime is left without judicial remedy. That the prosecutor must prove that the crime is committed by the defendant without reasonable doubt, means that there is much more chance of a Failure to convict guilty felons, than of the opposite.In the essay, the rules of criminal procedure directed at the evaluation of the verbal statement are identified and critically evaluated from the perspective of how they may or may not facilitate the judgment of a verbal statement presented before the court, either in person, or through other media such as video.
