Industriforskning och informationssökning: en användarstudie av en grupp forskare vid ABB Corporate Research

The thesis aims at, from a user perspective, examining how a group of industrial researchers understand the information seeking in their every day work. A qualitative method is employed. The empirical material consists of open-ended interviews with in all ten researchers. All of them work at the Swiss-Swedish Technology Company ABB's research laboratory in Västerås. The thesis is based on the opinion that the scientific knowledge production has become commercialised and that the scientific communication is going through certain changes.

"Sång får ju faktiskt människor att må bra" : Kören: hälsan å riten!

In this thesis you will meet people that are members of a ?health-choir?. This people are singing together once a week and the purpose is to get a better health. You will also see if choir-singing can be seen as A rites of Passage. You will get a direct link to the informants.

Globala och lokala sökmotorer: en utvärdering av Google, MSNSearch och Svesök

The purpose of this thesis is to evaluate three search engines with regard to retrieval effectiveness of information specific to Swedish users. Coverage and the precision in result descriptions are also examined. The three selected search engines are Google, MSN Search and Svesök. 30 queries were tested against the search engines and the first 20 result descriptions and results were judged for relevancy. Relevancy was judged by a binary scale.

Evaluering av återvinningseffektiviteten i Svensk Medicin och Google Scholar med medicinska frågor ur Fråga doktorn.

The purpose of this thesis is to evaluate and compare the retrieval effectiveness of two search engines on the Internet: Svensk Medicin and Google Scholar. Svensk Medicin is a medicine-specific search engine and Google Scholar specialises in indexing scholarly material. A set of 20 questions in four categories were used to conduct the searches with the search engines. Genuine medical information needs were selected from a question collection provided by the television program Fråga doktorn. The relevance of the first 10 retrieved documents was judged by using a binary scale and the measure used was precision.

Faunapassager : How animals cross roads

A fauna passage is a way for animals to cross roads separated from the traffic. In Sweden, there are an unknown number of passages with different functions and appearances. These passages would, with the question ?Which fauna passages can be found in Sweden, and how well do they work?? as a base, be compiled in a comparable way. This would be done with a number of questions asked to the different regions of Vägverket.

Söktjänster för akademiskt bruk: En utvärdering av Google och Argos med frågor från en akademisk ämnesdisciplin

The purpose of this MSc thesis is to examine the retrieval effectiveness of two Web search engines with queries from the academic discipline of Classical Studies. The two search engines are chosen to represent two different types Google as a broad general search engine and Argos as a specialised search engine for the subject of Classical Studies. The search engines are compared for precision among the first twenty results returned for thirty queries. In order to avoid bias in the study, the queries are based on real users' information needs. Due to the subjective character of the concept of relevance, the study is performed with five different experiments with five different definitions of relevance.

Bostadsrätten och ägarlägenheten : en jämförande studie

Under ht08 och vt09 har vi gjort ett examensarbete där vi i gruppen utvecklat ett mekaniskt styrsystem för sjukhussängar. Det nya styrsystem ska underlätta det dagliga arbetet för personalen på sjukhusen, då det idag är svårt att kontrollera sängen när man är ensam och knuffar. Men med RaaLie fastmonterad på sängen kan man utföra arbetet själv, och det är mycket lättare att ta sig runt skarpa svängar och trånga passage..

Informationspraktik hos ensamföräldrar som genomgått assisterad befruktning

The aim of this paper is to examine the actualities of Information Practicefor single women whose parentage has been made possible through assistedreproduction, which places these parents in a norm-breaking position.Study issues related to parents? perceptions of information needs areinvestigated, as is the process of information retrieval and library usageas well as the obstacles and opportunities facing parents in search ofinformation related to their own family constellation. To this end, theoriesby Tom Wilson, Reijo Savolainen and Elfreda A. Chatman have been usedas a model of selection. Empirical data have been gathered from interviewswith eight single women, whose parentage has been made possible throughartificial insemination or IVF with sperm from an open or anonymousdonor.

Att ämnesbestämma bilder: En teoretisk undersökning

The aim of this master ´s thesis is to understand why there are difficulties in finding joint methods and standards in the field of image indexing. The main focus for interpreting these issues is on Sara Shatford ´s article Analyzing the Subject of a Picture: A Theoretical Approach. In the article Shatford discusses a theoretical basis for identifying and classifying the subject in a picture. In doing so she uses concepts taken from The Philosophy of Art, Meaning in Language and Visual Perception. With the aid of S.R.

En tesaurus som ledsagare ? En jämförande studie av tre sökstrategiers inverkan på återvinningsresultatet i en bibliografisk databas.

This Master?s thesis is a comparative study of information retrieval results between three distinct search strategies in simulated automatic query expansion in a bibliographic database. Our purpose is to investigate which of the search strategies score the most effective precision and to what extent the same relevant documents are retrieved (overlapped). A thesaurus attached to the database is used to select appropriate descriptors for the baseline query formulations which subsequently are expanded with hierarchical relations. The search strategies are s1: A baseline query with two or three descriptors, s2: The baseline descriptors combined with at least one Narrower Term, s3: The baseline descriptors combined with Narrower Term and at least one Broader Term.

Konststycket

Projektets utgångspunkt är ett nytt konstmuseum i Uppsala, i området bakom Uppsala centralstation, som nyligen genomgått ett ansiktslyft.Museets långsmala karaktär har hämtats från det intilliggande godsmagasinet och från tomtens form. Genom byggnaden har ett diagonalt stråk öppnats, för att ge möjlighet åt fotgängare att passera genom byggnaden och för att skapa liv och rörelse på platsen.Genom fönstren i passagen kan förbipasserande få en skymt av vad som händer inuti muséet. I passagen ligger museets entré, den pedagogiska verksamheten och ett kafé för allmänheten.Museets fasad är inspirerad av den arabiska mashrabiyan. Byggnaden har fönster längs hela fasaden, som i sin tur är täckta av skärmar tillverkade av sträckmetall. Ljuset tillåts komma in i byggnaden samtidigt som sträckmetallen täcker fasaden och bevarar något av museets hemligheter för förbipasserande.Museets inre väggar består av massiva betongskivor, placerade i ett rutnät som fått sin riktning av passagen genom huset.

Det relativa värdet av ämnesingångar i databaser: Variationer mellan discipliner

This thesis deals with tactics for information seeking in electronic databases. An important aspect is knowledge of the relative value of different subject access points. The method used here is literature studies. Nineteen empirical studies are described and analysed with the purpose to compare the relative value of different subject access points. The studies examined compare the relative value of subject access points in relation to each other or in relation to different scientific disciplines.

Antinutritionella substanser iåkerböna, ärter och blålupin vidutfodring till mjölkkor

There is a shortage of locally produced high quality protein concentrates in Europe andSweden. Local production would decrease the dependency on imported soybean and meet thedemand for organically grown feedstuff from ecological dairy farmers. Field bean (Viciafaba), peas (Pisum sativum) and sweet lupin (Lupinus angustifolius) are good alternatives tosoybean, but contain anti-nutritional substances (ANS) that could reduce their use as proteinconcentrates in dairy cow diets. The aim of this literature study was to review which ANSfield bean, peas and sweet lupin contain and whether they affect dairy cows negatively.Trypsin inhibitors and Chymotrypsin inhibitors (TI) were present in all three crops. TI couldbecome inactivated and degraded in the rumen, but due to the high passage speed of thedigesta, most TI left the rumen in an active state.

Safe retrieval of nutrients to improve food security

Safe retrieval of nutrients from human excreta to fertilize crops in order to gain adequate yields will increase food security and sustainability in agriculture areas with nutrient-poor fields. Safe and nutritious food will meet the dietary needs of the individual which promotes public health and the ability of an active life. Human excreta should be considered as a resource instead of being assumed as waste. Human faeces and urine is excellent fertilizers which may close the nutrient loop if utilized properly. However, sanitation of the excreta is required to prevent disease transmission by reducing the content of gastrointestinal pathogens such as bacteria, viruses and parasites. The objective of this study was to in small scale evaluate the sanitation in a combined liquid compost and urea treatment by monitor the inactivation of bacteria and viruses at the combination three start temperatures, 45, 40 and 35 °C, and three additions of urea, 0.5, 0.75 and 1 % and reference, 0 % urea addition.
