The paper aims to explore to what degree different types of terms in engineering information (Ei) thesaurus and classification scheme influence automated subject classification performance. Preferred terms, their synonyms, broader, narrower, related terms, and captions are examined in combination with a stemmer and a stop-word list. The algorithm comprises string-to-string matching between words i
Popular Abstract in Swedish Denna avhandling är inriktad på metoder för att förbättra och utvärdera infrastrukturer för geografiska data (eng. Spatial Data Infrastructure). Syftet har varit trefaldigt: att utveckla ett ramverk för hantering och utvärdering av en infrastruktur, att förbättra tillgängligheten av geografiska data i en infrastruktur, och för att förbättra kartografi i visningstjänsterThis thesis mainly focuses on methods for improving and evaluating Spatial Data Infrastructures (SDIs). The aim has been threefold: to develop a framework for the management and evaluation of an SDI, to improve the accessibility of spatial data in an SDI, and to improve the cartography in view services in an SDI. Spatial Data Infrastructure has been identified as an umbrella covering spatial data
History plays an important role in the philosophy of human rights, more so than in philosophical discussions on related concepts, such as justice. History tends to be used in order to make it credible that there is a tradition of rights as a moral idea, or an ethical ideal, that transcends national boundaries. In the example that I investigate in this chapter, this moral idea is tightly spun aroun
To manage increasingly complicated 3D city models, a framework based on NoSQL database is proposed in this paper. The framework supports import and export of 3D city model according to international standards such as CityGML, KML/COLLADA and X3D. We also suggest and implement 3D model analysis and visualization in the framework. For city model analysis, 3D geometry data and semantic information (s
Recent advances of body networks enable the acquisition of personal context from various kinds of body sensors. As a result, how to build a platform to properly manage personal context becomes a problem. In order to address this issue, we design and implement a mobile physical space gateway (MPSG) which is a generic context management framework in mobile spaces. This framework includes three layer
Many of the water bodies in Europe are in bad ecological condition due to anthropologic impacts. Pollution and morphological changes have had a severe impact of the water environment and flora and fauna associated with such environments. The fact that water courses often cross administrative borders within countries as well as internationally makes the water management that much more difficult. Th
The overall objective of this thesis was to investigate how CSR is approached by commercial banks in the U.S and Sweden respectively. We have therefore made a comparative analysis of the national differences in terms of CSR. This research was done by introducing and identifying dimensions that affect the CSR practices in each country. These dimensions have been analyzed based on the national busin
OMX spreads decline from 2001-2006. The average volume and average number of trades / trading frequency increases over this period, whereas the average trade size decreases consistent with greater retail investor activity. Macroeconomic factors such as interest rates, inflation rate and GDP rate do not seem to affect changes in the spreads.

In this report, the implementation of a technology called sensor-based sorting technology is analyzed from different perspectives. The technology can be used to identify individual particles in order to sort wanted material from unwanted material. Today, the technology is widely used in different industries such as the food industry, the recycling industry, and to some extent the mining and minera
This thesis investigates the ontological meta-narratives of glitch art and focuses on it as the transition from images with noise, into a site of meaning. In the first chapter I will discuss glitch art as a failure in communication that stimulates our perception. By relating glitch art to noise art, I will describe the prevalence of a common artistic approach towards errors, while through Fiske’s
The purpose of this thesis is to explore the possibility of asymmetry in the dynamic conditional correlation of stock returns and gold returns. We hypothesize that this asymmetry might be different for large and small firms, as a result of size specific characteristics that may influence firm profitability and risk following negative market shocks. We investigate this on three different sized U.S.
The sun is an important reason to why there is life on earth. To be able to predict future solar activity it is important to uncover past solar activity and its cyclicity. This thesis investigates the solar activity throughout the past 2000-years to the beginning of 21th century. Diagrams which contain relevant data from radionuclide and sunspot records have been constructed to get a better overvi
This paper addresses the Environmental Management System (EMS) frameworks among the twenty-five biggest oil companies in the world. An Environmental Management System is a framework which can be used by companies to structurally control and manage their environmental aspects and impacts. Specifically in this study, focus is put on the content and structural set-up of EMS frameworks. The study look
It is indisputable that in order for an organization to act within a society, legitimacy is needed. A peace-building organization in a post-war society this might be even truer. This thesis attempt to answer how it is possible to understand legitimacy in relation to peace-building. By participating observational study and semi-structured interviews I have collected empirical material from a peace-
