This report is an inventory of the street lighting in half of the residential estates owned by Karlstad Bostads AB, a public housing company. The inventory was made to reduce the environmental impact of the street lighting. From the inventory an estimation of the total installed power and the energy consumption was made. The total estimated power of the street lighting was 125 kW and the energy consumption was 500 000 kWh/year with an estimated running time of 4 000 h/year. The dominating source of light was 125 W discharge mercury lamps.

The aim of this master thesis is to evaluate the performance of the content-based image retrieval system ImBrowse from a semantic point of view. Evaluation of retrieval performance is a problem in content-based image retrieval (CBIR). There are many different methods for measuring the performance of content-based image retrieval systems, but no common way for performing the evaluation. The main focus is on image retrieval regarding the extraction of the visual features in the image, from three semantic levels. The thesis tries to elucidate the semantic gap, which is the problem when the systems extraction of the visual features from the image and the user?s interpretation of that same information do not correspond.

This study in the subject of forest planning is made for Sveaskog and its aim is to develop tools that prognosticate outcome in terms of volumes per sort from not yet cut forest stands. The degree of detail is just to get reliable results for at least one months volumes, for Sveaskogs own forestland in the market region of Norrbotten that is about 100 000 m3fub. The course of action to accomplish this is regression analysis and the data consists of cut tracts on own forestland in Norrbotten during the years 2006, 2007 and 2008. That is a little more than 4 million m3fub. Two tools were made.

Livestock of pastoralists provide meat, milk, blood, dung and are useful for transportation purposes. In semi-arid and arid areas with very low precipitation the herder must often walk far distances to feed the livestock. This affects the animals? production, especially of milk. Previous studies have investigated how to improve milk production in terms of milking strategies in cattle.

In this bachelor thesis a complete prototype of an industrial vibration measurement platform has been developed.

The aim is to evaluate hardware and software solutions for a possible future product. Based on a requirement specification a proper hardware design has be developed. The hardware consists of a four-layer PCB with an ARM Cortex-M3 microcontroller and about 250 other components. The PCB was designed, assembled, tested and finally housed in a box.

The state of our society is frequently changing. Due to various factors, the pressure of creating a changeable city is high and necessary to adequately supply the needs for its inhabitants. But making these changes and adapt to the fast shifting state of the city is not always physical possible. Young adults and students is a group that often seeks to move to intensely growing city regions. The reason for this is a more promising job market and more attractive educations, but coincidentally the shortage of housing is extremely high in these areas.

The assignment is issued by Scania Maintence AB seeking a new approach to detect power changes in their industrial processes. The work has taken place at Ångströmslaboratoriet and tests have been performed at Scania AB Södertälje.Today?s society consumes enormous amount of energy. In both economically and environmental view, it is important that the processes are effective, with high power factor. There are many ways to measure power in the industry, what they all have in common is that the installation is advanced, requires time and planning.

A possible treatment for patients with lymphoma and myeloma is stem cell transplantation (SCT). SCT is preceded with cytostatic treatment. There are several side effects related to this treatment, for example fatigue, nausea, constipation/diarrhoea, pain, mucositis and loss of appetite. Aim: Investigate which side effects related to the treatment where most troubling after SCT and if nurse assessment and patient assessment differ. Methods: A quantitative empirical study with repeated measuring.

Present master of science thesis has been carried out at the Swedish Road Administration consulting services (Vägverket Konsult) in Karlstad. The purpose of the study is to investigate how well the calculated drawdown of the groundwater table predicts the actual drawdown when the road and railway gates at the studied sites are built. For this purpose the groundwater levels at the three bridges were measured during 6 months. The bridges in question are two railway bridges situated in Ölme and Ulvåker and one road bridge crossing a pedestrian and cycling path in Lidköping.In Ölme the calculated area of influence was smaller than the measured one. It differed up to 30 meters, i.e.

This is a study on individual development plans (IDPs) in pre-school and their relationship with the teaching performed. Skolverket does not mention the IDPs in their steering documents for pre-school, and have in a separate memo discouraged from the use. Yet reports show that many of the pre-schools in Sweden are using IDPs. Teaching in pre-school is expected to be a mixture of care and learning without clear boundaries to the scientific topics pre-school aims to introduce children to. The purpose of this study is to investigate if the use of IDPs affect the teaching in pre-school.

AbstractThe aim of this essay is to understand the view of man as a creature in the Norse culture by studying rituals and ritual actions in conjunction with homicide. The material on which the study is based is called the Icelandic sagas, which are important source of information to the Norse culture. To achieve the purpose, I used a qualitative content analysis and qualitative narrative analysis along with ritual theories based on Roy A Rappaport among others. The questions are for instance:- What ritual actions occur in connection with the homicide, according to the Icelandic sagas? - What are the differences in how individuals are treated in passages where the ritual actions in relation to homicide and homicide cases investigated and why?The results show four different types of ritual acts in relation to homicide.

By applying a segmentation procedure to two different sets of computed tomography scans, two geometrical models of the abdominal aorta, containing one inlet and two outlets have been constructed. One of these depicts a healthy blood vessel while the other displays one afflicted with a Abdominal Aortic Aneurysm. After inputting these geometries into the computational dynamics software FLUENT, six simulations of laminar, stationary flow of a fluid that was assumed to be Newtonian were performed. The mass flow rate across the model outlet boundaries was varied for the different simulations to produce a basis for a parameter analysis study. The segmentation data was also used as input data to a surface description procedure which produced not only the surface itself, but also the first and second directional derivatives in every one of its defining spatial data points.

To turn the dairy heifers out on pasture is the most natural way for the cattle to get feed. At the same time it is cheap and if it is right treated a feed of high nutritive value. The problem today is to get dairy heifers to grow enough when they are grazing at natural pasture for the entire summer. Therefore, the opinions differ whether pasture is a resource or a problem. The increasing interest of pasture production is due to the fact that you can receive grants for preserving valuable natural assets and cultural landscape elements in the pasture land. A high grazing pressure is necessary to preserve an open landscape and a great variety of species. In the same time the heifers have to supply their nutritive needs in order to grow and be large enough to show heat and be pregnant in right time to calve with a sufficient body size and at an economically right age. This paper includes a literature review on natural pasture, pasture production, and growth of dairy heifers together with own interviews with dairy farmers about their point of view to the pasture husbandry on the farms, how they plan for pasture, look after natural pasture, treatment areas and take care of the calves and heifers. The results indicate that the time it takes and the demanded work are the biggest factors to how and why the farmers do as they do..

The aim of this study was to examine how the activities of two preschools develop the language in matter of the teacher?s work of procedure. The following research questions were essential for the survey and therefore formed the basis of the examination:How do the teachers in both preschools work in a language evolving way?What significance does the environment have for the language development?Are there similarities and differences between the preschools in their language development approach?The study is based on a qualitative method, where the teachers of both preschools were interviewed with the purpose of obtaining information. The teacher?s statements and interviews were analyzed in relation to previous research, where the theories of different writers form the base of the theoretical connection to the study.The teachers view in developing the language regarding to their aspirations in measuring the language an important position in their operation, can be portraied as the conclusions of this study.
