When the emissions from the diesel trucks today accounts for a large part of the total emissions from the road traffic, the trend with a more extensive use of diesel trucks for transportation will therefore lead to increasing carbondioxide emissions to the atmosphere. Because of the fact that technical progress in the form of optimized engines and shifts in the means of transport sometimes result in even greater emission levels, other solutions to this problem must be studied to decrease the emissions of carbondioxide from the diesel trucks. The purpose of the thesis is to show how a decrease of the carbondioxide emissions from diesel trucks in Sweden can be achieved in a costeffective way by the use of a carbondioxide tax and a differentiated vehicle tax. The method used in order to fullfill the purpose of the thesis is studies of literature, mainly of public government reports. Literature of enviromental economics will be used to show the need of a tax and how to determine the dynamic effective carbondioxide tax in steady-state.

Just how far is it possible to make learning of new parts for recognition and robot picking autonomous? This thesis initially gives the prerequisites for the steps in learning and calibration that are to be automated. Among these tasks are to select a suitable part model from numerous candidates with the help of a new part segmenter, as well as computing the spatial extent of this part, facilitating robotic collision handling. Other tasks are to analyze the part model in order to highlight correct and suitable edge segments for increasing pattern matching certainty, and to choose appropriate acceptance levels for pattern matching. Furthermore, tasks deal with simplifying camera calibration by analyzing the calibration pattern, as well as compensating for differences in perspective at great depth variations, by calculating the centre of perspective of the image.

The aim of the present study was to investigate response time variations in tasks for assessment of high level language functions and how response time is related to education, age and gender. Response time is defined as the time to complete a task after it has been presented. 103 subjects, aged 20 to 80 years, were tested with the Assessment of Subtle Language Disorders, Sentence analysis and Morphological completion. The subtest Comprehension of ambiguous sentences showed the longest response time and Morphological completion the shortest. Correlations were found between increasing age and longer response time for Comprehension of metaphors and between education and response time for several subtests.

The number of blogs, from weblogs, are increasing every day. Blogs are also becoming more visible in the public debate as well as the awareness of their existance is rising among politicians and citizens. The aim of this thesis is to answer the question what democratic potential blogs can have. This question will be answered by initially studying the research that exists today about weblogs and democracy. The second part of the analysis consists of a selection of texts from weblogs that touches this subject.

Is the Muslim Brotherhood a political force that can be able to push Egyptian society in to the process of democratization? We think that the answer to that question is yes, even though the movement clearly state that their main aim to create a democratic state, but based upon the Islamic shari?ah-laws. In this paper, we examine if the Brotherhoods? political platforms and ideas are compatible with the classic ideas of how a democratic state should be. We discuss Robert A.

The share of human beings with overweight or obesity is increasing. This has become a problem for society since obesity often leads to illness. This illness affects life negatively and often leads to depression, absence from work and medical care. One treatment against obesity is to do bariatric surgery, or Gastric bypass. The purpose of the study was to illuminate the experiences of care encompassing Gastric bypass surgery.

The retailing landscape has become even more competitive with an increasing number of store formats. One result of this can be seen within different retail-chains as they launch different formats that operate under the same name. Thus, consumers now have many alternatives and substitutes when it comes to choosing which format to shop from. This phenomenon has led consumes to shop across stores for the same brand. The objective of this study is to explain how consumers respond to various offers in different store formats and to determine whether the results differ if we compare a familiar brand with an unfamiliar brand.

Handling product returns has become a critical activity for organizations as the volume of gods flowing back through the supply chain rapidly increases. Few research studies have published specific empirical data concerning the reverse logistics practices of companies. Information technology and information support has long been recognized as a competitive weapon ? capable of enhancing company performance and achieving efficient reverse logistics. Reverse logistics is very unlike the forward, as it is more reactive and also has less visibility.

Increasing attention is being given to acid sulphate soils wherever they occur. The problems that leaching sulphate soils gives with significant lowerings of pH and mobilization of heavy metals influence large spectra of our society from fisheries to agriculture to construction. Mapping these soils is consequently of great importance and the methods of doing this is very much lacking in function and precision. This study was therefore carried out to investigate whether conductivity in running water can be used as a simple instrument to identify acid sulphate soils in the catchment. 31 coastal streams in the county of Västerbotten were analyzed for different catchment properties such as occurence of marine sediments and basic water chemistry including conductivity and sulphate.

Alzheimer?s disease has increasing effects on the Swedish population. Now, about 90 000 swedes have been diagnosed with the disease. Many of these persons are cared for by someone close to them. The aim of this study is to increase understanding for the situation and experiences of the persons caring for their affected partner and to examine which support they are given by the public sector.

With increasing wine consumption and a growing assortment at available to Swedish consumers, there is an interest in understanding the decision making process of Swedish wine consumers. In this thesis the expert phenomenon is studied with respect to wine through wine critic reliability: grading objectivity, understanding the process of wine criticism and possible critic influence on consumer behavior. Two studies were performed; a qualitative in-depth session of interviews with industry connoisseurs and a quantitative analysis of 589 online wine reviews. Our results indicate that wine reviews are highly subjective and defy prediction through analysis of external variables. Critics are likely to judge differently based on what information they have at hand, suggesting that expectations affect grading.

Background: The increasing number of actors on the market has led to a more intense competition among superstores. With this, marketing has gotten an even more essential meaning. The marketing activities superstores perform are adapted to the context in which the store is located. Purpose: The purpose of this thesis is to, from different theoretical dimensions, compare superstores? application of marketing strategies in Tokyo with the marketing strategies used by superstores in Stockholm.

The number of people that are categorized as being homeless in the Swedish society are increasing. This might be an indication that the methods being used today shows not to be working efficient enough. A group of researchers connected to the University of Lund are now in a process to spread new workingmethods against the problems with homelessness in Sweden. Their goal is to completely erase homelessness as a social problem. This new method of working is distinctively different from the one currently beeing used.

The aim of this thesis was to investigate how the use of the IT-personnelsystem influences human resources and the new challenges and future requirements that may occur, while IT-personnelsystem is used more extensively in the HR-function.Previous research referred to in this study, has focused on how the HR-transformation has contributed to the development of an IT-personnelsystem, which has been used with increasing frequency. This use has created a significant change in the HR-function. This thesis focuses on investigating, describing and analyzing how the practice and development of the IT-personnelsystem meets the needs of the HR-transformation.This study uses qualitative research methods to investigate sixteen users? experiences and our understanding and conclusion is based on both semi-structured interviews and webb surveys. Initially deductive, later on our study took a more abductive approach.The result indicated a variety of uses for a specific IT-personnelsystem dependent on the users? function and positions and also how HR-activity was organized within the business.
