Our population are ageing. As this happens more people will be in need of long term care facilities. We now know that some elderly people with certain background factors are more likely to be injured or sick. One of the four biggest background factors is fall propensity. Most of the reported falls come from long term care facilities, approximately 60 % of the care takers in long term care facilities fall one time or more each year.

From a time where employees often remained at one company until retirement, globalization and changed employment patterns have created a more mobile labor market in the last years. In an effort to expand the connection between organization and employee a rising interest in corporate alumni networks has emerged. Previous research has shown that conditions for such networks are formed through employees social identification, perceived organizational support and organizational citizenship and can be shaped by company's HR practices.This paper aims to examine two case companies' perceived benefits through alumni relations as well as their HR prac-tices, in order to increase understanding surrounding the relationship between the two areas. Further the study intends to draw conclusions about the role of corporate alumni networks in the creation of the received benefits.The study indicates that HR practices, through the creation of an organizational citizenship behavior, can influence the conditions for beneficial alumni relations. Results show that some expected benefits of alumni relations can be re-ceived through strong citizenship.

?Medicines are available in different forms and often have different types of compound components. More and more drugs are found on the market. This means that professionals who handle different medicines must have access to more and more information.The information available includes information about side effects, active substances, interactions and pill identification. You may want to access different information, depending on your profession.

The use of spread spectrum signals has increased dramatically in military applications. Finding methods for detecting and positioning of these signals have become interesting research areas for signal intelligence purposes. One method is to measure the time difference of arrival (TDOA) that occurs when two receivers are synchronous and spatially separated. Based on the TDOA-technique an audio-demonstrator has been developed and implemented. This report describes the theory for how sound received in microphones can be used to extract information about the transmitter?s position from the measured time difference.

This report is part of the major thesis carried out at Stoneridge Electronics in Bromma,Stockholm during autumn and winter 2005-2006. The background to the thesis is the trendwithin the automotive industry where color displays have become more common for presentationof information to the driver, a trend that has come to the commercial vehicle market. Thepurpose of the thesis has been to evaluate whether programmable logic, with respect to FPGAtechnology, could be suitable for display control and graphics generation of these more complexcolor displays in automotive environment.Within the scope of the thesis the FPGA technology has been investigated, i.e. whatopportunities and threats there are with aspect to environmental and security requirements. Inaddition, the market of FPGAs and pre-built IP-cores has been investigated.

The purpose of this study was to understand what the professionals experiences are of stressed youth. We did a qualitative study with interviewing three school nurses, one welfare officer and two recreation leaders. Research is saying that stress is increasing among the youth and that girls are more stressed than boys. It also says that medium is a big consequent for that (ex. Brun M.

To render outdoor scenes with lots of vegetation in real time is a big challenge. This problem has important applications in the areas of visualization and simulation. Some progress has been made the last years, but a previously unsolved difficulty has been to combine high rendering quality with abundant variation in scenes. I present a method to mathematically generate and render vegetation in real time, with implementation in the scene graph Gizmo3D. The most important quality of the method is its ability to render scenes with many unique specimens with very low aliasing.

Several studies have analysed the relationship between Normalised DifferenceVegetation Index (NDVI) and radiative surface temperature. A main goal for moststudies have been to find the best method for carrying out land cover classificationsand to study land cover changes, based on a combination between the twoparameters. Since atmospheric components have a significant influence on bothparameters, most applications were based on multi-temporal data. The quality of theindividual values in such a combination is improved, but the biophysical justificationis uncertain. This study presents a different method, based on only the combination ofvalues that have been registered the same day and about the same time of the day.125 daily images of NDVI and 250 images of radiometric temperature were used inorder to analyse the relationship between (1) NDVI and radiative temperature and (2)NDVI and relative temperature difference between early morning and mid-day.Results between NDVI and radiative temperature show a significant negativecorrelation on areas where a distinct growing season develops, and a strong positivcorrelation where vegetation is abscent throghout the season.

Yesterdays common fertilizing strategy was to apply phosphor (P) and potassium (K) in thefall a few times in the crop rotation. In the spring only nitrogen (N) was applied. Recent trialsand studies has shown that this strategy, N+P/PK, is ineffective compared with the systemwhere NPK is spread every year in the spring. The strategy with annual NPK-fertilizer in thespring has proven to be better for the crop, the environment and the farmers economy.In the NPK-system the crop responds with higher yields and better quality, especially in thespring cereals. This is mainly because of an interaction between the different nutrients in thefertilizer.

This essay is about the planning of Stockholm's border regions (areas on the outskirts of the city) during the first seven years of the 21st century. It describes how planning decisions are made in reality, in respect to a 'green' perspective. By describing what a "markanvisning" is (the right to negotiate with the city about a certain piece of land) and by discussing examples of what has happened with a hundred applications for markanvisning, this essay shows how Stockholm's border regions are planned. In the majority of cases it is the initiative of the future developers that begin the planning and construction processes. Research shows that the application to get a markanvisning in Stockholm does not follow a clear, structured system. However, the existing system in Stockholm does work and it seems like almost all the employees within the municipality, the politicians, and the future proprietors are happy with the current situation. Interviews have been held with key individuals involved in the planning process.

The subject of this thesis is the application of Support Vector Machines on two totally different applications, facial expressions recognition and remote sensing.The basic idea of kernel algorithms is to transpose input data in a higher dimensional space, the feature space, in which linear operations on the data can be processed more easily. These operations in the feature space can be expressed in terms of input data thanks to the kernel functions. Support Vector Machines is a classifier using this kernel method by computing, in the feature space and on basis of examples of the different classes, hyperplanes that separate the classes. The hyperplanes in the feature space correspond to non linear surfaces in the input space.Concerning facial expressions, the aim is to train and test a classifier able to recognise, on basis of some pictures of faces, which emotion (among these six ones: anger, disgust, fear, joy, sad, and surprise) that is expressed by the person in the picture. In this application, each picture has to be seen has a point in an N-dimensional space where N is the number of pixels in the image.The second application is the detection of camouflage nets hidden in vegetation using a hyperspectral image taken by an aircraft.

This final thesis was performed at Ericsson in Gävle between April and June of 2008. Ericsson is a world leading manufacturer of radio base stations (RBS), which handles mobile phone traffic with 2G and 3G technology. The main purpose of this study is to examine if two different types of products (RBS and site material) should have different terms and conditions, today the terms and conditions are the same for both types. During the course of our study we have tried to think of the terms reliability, validity and generalization. The intention in doing that was to keep the thesis at a high academic level. To name an example of this we have tried to keep our minds at an objective level during the interviews and informal conversations.

In today?s computerized society more and more companies choose to utilize new applications that can ease the way of handling the information. For many of us is imperative that the process as efficient as possible if one takes in consideration the size of savings that this new application can bring.The developer of the evaluated system is SYSteam AB Huskvarna and they are the ones that gave us this assignment. The application that we evaluate is SCM (Secure Connection Manager). It is already used today by big companies such as Telia and Ericsson to search for errors in telephone servers placed all over the country.

The interest in tiny wireless applications raises the demand for an integrated reference oscillator with the same performance as the macroscopic quartz crystal reference oscillators. The main challenge of the thesis is to prove that it is possible to build a MEMS based oscillator that approaches the accuracy level of existing quartz crystal oscillators. The MEMS resonator samples which Philips provides are measured and an equivalent electrical model is designed for them. This model is used in the simulations of the Pierce oscillator and the transresistance amplifier oscillator that are evaluated in this thesis. Finally the Pierce oscillator is implemented in the A BCD2 process and manufactured at Philips Semiconductors in Nijmegen, The Netherlands.
