This paper presents techniques for speeding up commonly used algorithms forbounding volume (BV) computation, such as the AABB, sphere and k-DOP. Byexploiting the possibilities of parallelismin modern processors, the result exceedsthe expected theoretical result. The methods focus on data-level-parallelism(DLP) using Intel?s SSE instructions, for operations on 4 parallel independentsingle precision floating point values, with a theoretical speed-up factor of 4 ondata throughput. Still, a speed-up between 7?9 are shown in the computation ofAABBs and k-DOPs.

This study examines whether a spatial relationship exists between blue-green infrastructure and indicators of gentrification in Hisingen, Gothenburg, during the period 2015?2023. Using a GIS-based approach, sociodemographic changes across 83 demographic statistical areas (DeSO) were analysed in relation to six parks established or significantly developed during the study period. Changes in mean income, educational attainment, share of residents with foreign background, and mean age were combined into a gentrification index, which was then tested against distance to the nearest park through linear regression analysis.The results show that socioeconomic changes consistent with gentrification occurred across parts of Hisingen during the period, with the highest index values concentrated in the central and south-eastern parts of the district. However, these changes were geographically selective rather than district-wide.

Everyday life mobility of elderly people ? opportunities, restrictions and sustainable urban visions aim to examine and describe elderly people?s movement patterns, their opportunities and restrictions of reaching high mobility and accessibility, and their attitude towards various sustainable urban visions. This paper is based on an approach of time-space geography as it covers the topic of movements in time-space, explained and developed using the concepts of mobility and accessibility. To examine elderly people?s attitude towards sustainable urban visions, this paper also takes approach on theories such as New Urbanism, mixed-use and the compact city.The method used in the study is an interweaving of a time geographic diary and qualitative interviews, where the respondents are six retired people between 68 and 77 years old living in Gothenburg city.

The retailing industry has an extremely high density of brands. In order to differentiate its offer, both retailers and suppliers, are constantly forced to come up with new ways to launch their products. A collaborative strategy between two brands is called co-branding, which means that both the private label and the supplier's brand are displayed on the new product packaging. Several studies have shown that a co-branding strategy is successful, but many operators are still reluctant to use co-branding in fear of long-term losses due to potentially damaged business relations. The objective of this study is to explain how the product- and brand related value for customers, retailers and suppliers is affected by co-branding between private labels and national brands.

The study aims to demonstrate the significance of educators lived experiences of stimulating children's physical development. It has been noted that children are occupying themselves with more and more sedentary activities, which may lead to that they do not develop motor skills at the pace expected. To understand educators lived experiences from a phenomenological hermeneutic perspective empirical relevance has been collected through narrative interviews. The results shows that educators find it difficult to understand the Curriculum goals for motor activity and that the desire to stimulate motor development is great, but the realization is conspicuous by its absence. The discussion highlights educator?s commitment and motivation and the importance of being a reflecting practitioner..

This essay is a comparison according to the ideological thoughts about womens position in the society of Mao Zedong och Josef Stalin. The material I have analysed is writings by Mao and Stalin, in a wide range from leaflets to orders to the armies of the states of China and the Soviet Union. The method I have used is an ideological analysis where the attitude towards women is the target for my survey. The attitude towards women generally was not unified in the world during the time for Mao and Stalin. In many countries the women was intended to take care of the children and the home, not be active in working and fighting.

The thesis main objective is to establish the determinants for granting executive stock options and to examine their impact on performance for firms listed on OMXS30. The analysis is based on accounting data gathered from annual reports and Thomson Datastream. The empirical results display that firms grant stock options to mitigate the principal-agent problem. Furthermore, risk proves to be positively significant with executive stock options, implying that either executives increase the level of risk after being granted stock options or influence the decision of the remuneration towards stock options when the firm increase the level of risk, in purpose to boost the expected value of their options. No relation between executive stock options and firm performance could be established..

This paper studies the option market?s implied dividend as a predictor of future equity market returns. We introduce this variable in the simple total return framework and discuss some complications of using it as a proxy for the expected dividend. We construct some regressions using the price-dividend ratio and the implied dividend growth, and test them on six years worth of data on the EURO STOXX 50-index. The main result is that implied dividend growth exhibits some forecastability over two-year horizons, but that the dataset is too short to draw any definitive conclusions about long-horizon forecastability.

Background: People are individuals who react differently when confronted with unexpected events. To miscarry is nature?s own way of sorting out the foetuses which could never become a fully grown child. The loss can without help be difficult to handle and can impact the couple negatively towards future pregnancies. The nursing staff ought to familiarize themselves with the experience, encounter their feelings and identify their needs.

The increasing road traffic in Sweden will require investments in the infrastructure that the tax withdrawal of today will not allow according to a new government report, SOU 2006:33. An existing willingness to pay for those investments has therefore become an alternative to increases in taxation to be able to cover the costs. A proposal to let the willingness to pay, alternatively increases in taxation that act proportional, decide how a cost is distributed can be said to be related, but not fully correspond, with different theories of justice described by Robert Nozick and John Rawls. It can therefore be interesting to see how the two different theories of justice are edified and how they distribute a joint cost. The aim of the first part of the thesis is to present and criticize Rawls' and Nozick's theories of justice in a common formulated economic model.

Background: 2007 there was 42 000 fall related accidents in Sweden and they are expected to increase the next few years. Fall among elders results in both increasing economically costs and suffering, but they can be prevented. For example has physical exercise shown an increasing effect on the risk for falls. Aim: The aim of this literature review was to investigate what influence Tai Chi has on the risk for falling among elder. Method: A literature review was conducted where eleven scientific articles were analysed with inspiration of the content analysis.

The aim of this study is to describe and analyse the knowledge of three of the treatment methods used in youth welfare and this is accomplished through a knowledge review. This study contains an analysis of three different treatment methods described in eleven different peer reviewed articles. The articles are all internationally published between the years 2006 to 2012 and they are all effectiveness evaluations. The articles deal with treatment methods concerning Motivational interviewing (MI), Aggression Replacement Training (ART) and Cognitive behavioural therapy (CBT) and these are three of the most common in youth welfare in Sweden. There is not much knowledge of Swedish conditions and that is why this study focuses on international research.

The number of HIV- positive is increasing all over the world and it's very likely to meet these patients as a nurse. The interaction between the nurse and the patient is characterized by experience and knowledge and at the same time the nurse is expected to act professionally. The purpose of this literature review is to investigate the nurse's complex of problems regarding the treatment of the HIV- positive patient by exploring the attitudes against HIV among nurses and how the nurse can maintain the integrity of the HIV- positive patient. Antonovsky's salutoqenic model, sense of coherence, has been used as theoretical frame. From 14 articles five topics have been found that influence the nurse's attitudes against HIV-positive patients.

The purpose of this essay was to compare the Swedish and the Japanese pension system and see if there were any big differences or similarities. I was looking for answers to such questions as if the systems were modelled with the problematic demographic situation in mind and also how these two countries had tried to manage the problems. Path dependency was also a central conception when I studied the reforms of the two pension systems. I mainly used literature and Internet sources in my study. There were many books on the Swedish pension system and the debates that had been going on since the 80's.

TCP (Transmission Control Protocol) is a transport protocol designed for the wired Internet. In wireless networks packet losses occur more frequently due to the unreliability of the physical link. The main problem is that TCP treats all losses as congestion, which leads to a lower throughput. Ad hoc networks are multihop wireless networks of mobile nodes, where each node can allow other packets to pass through it. Topology changes often occur and may lead to packet losses and delays, which TCP misinterprets as congestion.
