The aim of this masters thesis is to, from a queertheoretical point of view, examine the possibilities to classify the subject homosexuality in three different classification systems. The three systems that have been analysed is the Swedish classification system SAB, the Universal Decimal Classification UDC and Dewey Decimal Classification DDC. The analysed editions are updates from the beginning of the 1970´s until today. The emphasis has been on how well the systems correspond to the changing society. We found several differences between the three systems, but also some resemblances.

Heartwood has always been a desirable part of the tree, due to it?s superior decay qualities com-pared to the sapwood. How the formation of heartwood works has been known for a long time, but which factors that initiates and stimulates the production are poorly understood. This case study presents the results of a study in which silvicultural treatments and site properties had a key position as factors to the formation of heartwood. According to the hypothesis the amount of sapwood is directly controlled by the size of the crown.

Eutrophication of lakes and streams are nowadays a well known environmental problem and implies an enrichment of the nutrients phosphorus (P) and nitrogen (N). Phosphorus is considered to be the most important component for the growth of aquatic plants and leads in too large quantities to an intensification of growth. Phosphate (PO4) is the fraction of phosphorus that can easiest be taken up by plants and thus have the greatest impact on eutrophication. Increased plant growth in lakes and unfavorable conditions for aquatic animals are two examples of negative consequences. A significant portion of the increased nutrient supply to nearby water can be derived to phosphate leaching from agricultural areas, where private sewers and agriculture is two main sources.

Companies today need to be more focused than ever on having an active Human Resource Management culture. This is not only because of the companies? concern for their staffs wellbeing, but for the companies? effectiveness in the long run. The reward systems which many corporations use today, to both keep their employees and attract new ones, is a well researched subject by scholars as well as journalists. Earlier research has suggested that it is important to implement an active Human Resource Strategy.

This master thesis covers the development of an automatic tuning process for the existing speed controller for drive systems. The drive systems are resonant two-mass systems where a motor is used to drive a load connected by a shaft. The developed method relies heavily on system identification and the construction of a complete mechanical model of the process. With this approach, the common problem with poor load speed control that derives from measuring only the motor speed can be addressed and solved for a majority of such processes.The automatic tuning method has along with general test functions been implemented in a complete tool for automatic tuning, testing and performance evaluation and reporting for drive systems..

This thesis deals with subject-based hierarchical search-services on the World Wide Web. The purpose is to investigate how systems of this kind facilitate information retrieval through subject-based information seeking. Its starting point is taken from the study of texts and qualitative analyses of search-services on the World Wide Web. Important aspects and features of the Internet and the World Wide Web are explained as well. Three systems are examined: Mölndals Stadsbiblioteks Länkkatalog, Svesök, and Alta Vista.

This thesis is about informal seatings, those which are planned to merge into the city core environment and to supply a flexible public space. The thesis discusses how a diverse range of elements could result in different functions and social meanings. These are illustrated with visual examples and conceptual drawings. The position of the seating in a small public place is important, as well as its location in the city. Furthermore, the detail design of the seating, such as the form and dimensions have to be considered in order to create an informal seating appropriate for the user. This leads to the broad scope of this thesis which deals with the small scale - how the seatings can create a good environment in a small place; and the big scale - how a site can influence the city. This thesis suggests the physical design of some informal seatings and also investigates how these seatings can strengthen the place through their function and how they relate to their surroundings.

Building Automation Systems in commercial buildings are often designed and installed by different contractors, using equipment and components from different manufacturers. The lack of an accepted communication standard has resulted in a few different standards. Many manufacturers of building automation systems only support one, a few or none of these standards, while developing proprietary system solutions. Regin, who develop such equipment, are planning to adopt an open communication protocol specially designed for building automation - BACnet. As a step in that direction this thesis was announced with the purpose to investigate the possibility to implement BACnet in one of their products and to gain more knowledge of the BACnet protocol.

Information handling has been a key issue for different companies for a long time. Electronic Data Interchange (EDI) is used to transfer different business documents from one company to another. This is done in such way that the information itself is separated from how this information is stored and handled in the companies internal systems. As different companies have different systems there is a need for a standardised format for this exchange. There is a big difference between EDI-systems based on what kind of EDI-standard is used.

The city of Kalmar has a desire that their 3D maps of the city should come to a greater use and get residents more involved in Kalmar city. The purpose of this report is to show one way to work with these 3D maps when it comes to presenting information about Kalmar for its residents and tourists in a specific area.  The report also includes information about advantages and disadvantages with the use of 2D and 3D maps in different environments. Various reports and other sources indicate an interest in 3D and a use for this, but even that 2D is still seen as a natural way to read a map. By collecting information from relevant literature, interviews and user testing, the group has obtained sufficient background information to present the results of a web site, where the visitor can navigate in both 2D and 3D in a specific area of Kalmar. User tests and surveys have been conducted in two rounds and the web site has been revised after their results..

The increased competition in e-commerce puts pressure on e-businesses which makes it even more important to influence the visitors on their e-commerce sites. An often overlooked marketing tool is atmospherics. With the increased focus on e-commerce from both traditional and new e-businesses this marketing tool becomes even more relevant. The aim of this thesis is to investigate how the atmosphere on an e-commerce site influences the customers' thoughts, emotions and behaviors. We examine the effects the level of stimulus on a website has on the customer's emotions, attitudes, intentions, behaviors as well as the relationship between these variables.

Prescribed burning was commonly used for site preparation in Sweden to establish new forests until the 1960?s, when mechanical scarification was introduced. During recent decades the interest in prescribed burnings has increased again, mainly due to certifications of forestry stating that 5% of the regeneration areas should be burned on dry and mesic soils. The objective of the study was to evaluate actual influence of prescribed burning compared to other site preparation on stand stem density, growth parameters and tree damages for Scots pine (Pinus sylvestris L.) after direct seeding and planting. The study also attempts to simulate growth until first thinning.

The purpose of this thesis has been to assess whether leaching from one particular Swedishlandfill site, Skörbytippen, is contributing to elevated levels of heavy metals in a ditch runningfrom the landfill site to the lake Mälaren in the communal region of Håbo kommun. Since theditch is stretching approximately five km downstream from the landfill site, in situ observationsand maps with known points of inflow was utilized to determine appropriate test points for thecollection of samples.Soil, water and sediment samples were collected and analyzed for content of organic material, pHand conductivity. Data on plant-available elements and total amounts of heavy metals wasacquired through ICP-analysis.The results show that the Skörby landfill is currently in the methane-forming anaerobedevelopment phase, which indicates that the concentration of free and complex-bound metals inthe leachate water should be low due to chemical binding with other landfill compounds. The pHof the sediment samples was generally one unit higher than the soil samples and some of themeasured data, such as pH and conductivity, show that an environmentally disturbing dischargeof some kind of strongly alkaline chemical(s) has been made from Benders? takpanneindustri inclose proximity to the landfill.

Real-time systems are required to answer to external stimuli within a specified time-period. For this to be possible, the systems behaviour must be predictable. The use of active databases in real-time systems introduces unpredictability in the system, e.g. due to their use of active rules. The behaviour in active databases is usually specified in ECA-rules.
