Vederlagsgrundande mätning med skördare

This study was performed in collaboration with Moelven Skog AB, Örebro district. The purpose of the study was to review existing literature in order to describe the current status of harvester based measurement technology as the way to provide information for calculating payment to the forest owners. In addition to this, a short survey was conducted to find out how a switch to harvester based measurement would affect the administrative workload on timber purchasers working for the district. The literature study shows that the harvester measurement technology is ready to use if it is combined with well-established routines for control of the harvesters, methods for automatic quality indexing of the timber and ways of creating pricelists specially adapted for harvester measurement. Pricing each stem seems to be the most promising method. Stem pricing has several benefits.

Klassifikation och definition av socialantropologi En jämförande studie ur ett hermeneutiskt perspektiv

The purpose of this thesis is to study the relationship between the definition and bibliographical classification of a certain academic subject; social anthropology. The theoretical framework consists of views held in Information Science regarding the definition and classification of subjects. The methodological onset is based on hermeneutical concepts that allow an extended analysis of abstract structures of thought. This analysis comprises of two parts; a descriptive analysis and a comparative analysis. The result of the descriptive analysis, whose aim is to describe the academic subject social anthropology, shows that this is not easy to define, instead it is nowadays almost the same as cultural anthropology.

Prognostisering av småbolagsindex

Analysarbetet av finansiella data i samband med prognostisering blir snabbt omfattande, både ur ett teoretiskt och ur ett empiriskt perspektiv. Prognosteorierna står mot varandra. Är marknaden starkt effektiv eller finns det prognosmöjligheter? Att genomföra en empirisk prognosstudie resulterar snabbt i krävande beräkningsintensiva prognosmodeller. Då prognoser för flera tidpunkter behövs så måste beräkningarna upprepas och använda olika delmängder av tidsserierna som beräkningsunderlag.

Transtaggning och ämnesordsaktivism : Indexering i händerna på Den Andra

This thesis emanates from the understanding that it is of importance that transgender-themed literature is indexed in accordance with how people who identify as trans name themselves and interpret the concept of trans. Based on interviews with representatives from controlled vocabularies and LibraryThing users who tag transgender-themed material, existing attitudes towards user influence in controlled vocabularies are described and the significance of tagging for transgender-themed material is looked into. With queer theory and postcolonial theory as its main framework the analysis looks at what possibilities there are for users to influence controlled vocabularies and explores possible strategies for a future library catalog that includes the voice of the Other. The study lands in the understanding that many of the resisting attitudes towards user influence within the systems for subject headings in fact lie in the systems? limitations.

Funktionella krav på metadata: En undersökning av Dublin Cores överensstämmelse med FRBR

The purpose of this master thesis is to examine how Dublin Core corresponds to the findings in the IFLA report Functional requirements for bibliographic records FRBR, and what consequences this correspondence has on the usability of Dublin Core as a bibliographic standard. While the study describes the conceptual model of FRBR and the entities work, expression, manifestation and item, its main focus is the mapping of attributes and relationships to the user tasks defined, namely to find, identify, select and obtain entities. The study makes a comparison between data that FRBR rates as highly important for any user task, and the elements defined in DCMI Metadata Terms. The outcome of the comparison is then analyzed as to how it affects Dublin Core's possibilities to assist in the different user tasks, and common problems are discussed. The results show that problems in expressing attributes and relationships through Dublin Core elements concern all of the four user tasks.

Anställdas attityder till bibliotek

This paper is about employees' opinion towards libraries. The target group consists of employees at industrial research institutes in Sweden. Libraries offer several more services today than they have done before.

Since I am curious about if this is true or not the purpose of this essay is to find out, through an attitude research, the employees', at industrial research institutes, opinion about library service.

Marginaliserad kunskap? ? En kritisk studie av representationen av genusvetenskaplig litteratur i klassifikationssystem och ämnesordslistor

The main focus of this master?s thesis concerns the relation between subject representation, power and gender. Classification systems and subject heading lists are products of their cultural and social context and some subjects and disciplines are given a greater value than others. Our aim in this thesis is twofold; to discuss and critically analyse the prevailing gender norms that are expressed trough classification systems and subject heading lists and to examine how they manage to represent gender studies as a multidisciplinary subject in theory as well as in practice. We are also discussing the particular problems with the representation of multidisciplinary subjects in general.

Analysis of Raspberry ringspot virus in raspberry by amplification of RNA-2

So far, only limited research has been carried out on viruses infecting raspberry, even though the diseases that these viruses cause result in economical losses for raspberry growers. Raspberry ringspot virus (RpRSV) belongs to the family Comoviridae and the genus Nepovirus. Nepoviruses are characterized by their icosahedral virus particles and bipartite genome of single-stranded (+) RNA (RNA-1 and RNA-2). These viruses are transmitted mainly by nematodes of the genus Longidorus, which feed on the roots of plants. RpRSV causes disease in raspberry, grapevine, strawberry and many other plants.

Doktorander i fysik söker information : en intervjuundersökning av forskarens första tid som informationssökare

The aim of this Master's thesis is to examine difficulties concerning information acquisition, use, and management experienced by graduate students in physics during their first years of research work. Semi-structured, qualitative interviews were carried out with nine doctoral students. The theoretical background for analysis of the material is based on the work of Patrick Wilson, with particular focus on the concept of cognitive authority, and on that of Lars Seldén, who has proposed the idea of an information seeking career running parallel to the academic career of the researcher. Results from the interviews indicate that most of the students, in the early stages of their information seeking careers, rely to a great extent on supervisors and more experienced colleagues when identifying material needed for the research project. In a situation where information of potential relevance is abundant and where experience and focus are not yet fully developed, senior researchers function as cognitive authorities and as guides to other cognitive authorities.

Detektering av krypterade filer

In contemporary encryption the vast amount of text subject to cracking has brought about the demand for methods distinguish files more likely to be encrypted. The encryption software Truecrypt can encrypt files that are not possible to identify with a file signature. To solve the detection problem, an algorithm sensitive to the absence of structure in the very code of files was developed. The program was written in the programming language EnScript which is built into the forensic software suite EnCase. The essential part of the algorithm therefore deployes the statistic of a chi-square test for deviance from a uniform distribution to distinguish files with contents that appear to be random.
