In the year 1800, about 5 % of the world population lived in cities (World Wide Fund for Nature, 2012, 3). Today that number is about 70 % in Europe and North America, and in 2050 it is expected to be 86 % in the developed world and 67 % in the developing world (www, UN, 2009). In addition, the global population is expected to increase with 2.2 billion people until 2050. As a result of the population increase more food has to be produced which requires more transport from the countryside to the cities. However, this flow of resources faces some difficulties.

The project was based on a request to improve an already existing program and hardware at the electrical engineering department at the royal institute of technology. For maximum ease of use, tests have been done on students to properly design the program for what it is meant to be used for. These tests have been transcribed and analysed, then brought back to the group in a discussion and then transcribed and analysed again, I call this process the ?four step process? (this process is presented and explained in chapter 6.4.). A part of this master thesis was also to analyse the four step process to enhance validity of this research.The project resulted in a new program with a new graphical view and features to help students and researchers to work with the technical tool for electromagnetic readings of planar objects.

AbstractThe Swedish National Board of Health and Welfare has since a year or so started to introduce a new way to work with childcare investigations within the social services. This new concept, BBIC, is meant to put the child?s needs in the first room rather than the grownup?s as it used to be before. This study is about to examine how BBIC affects the legal security of the children within these childcare investigations.BBIC was first developed in England after a massive criticism against the way that the foster home- and institutional care was handled. In Sweden, BBIC was first tested and developed into Swedish conditions in a few project municipalities for about five years but is now being introduced all over the country.

This paper is a study and comparison between the two Wireless LAN (WLAN) standards HiperLAN/2 and IEEE 802.11a. WLANs are used instead or together with ordinary LANs to increase mobility in for example an office. HiperLAN/2 is an European standard developed by ETSI and the IEEEs standard is American. A WLAN-card consists roughly of a Medium Access Control (MAC), Physichal layer (PHY) and an antenna. The antenna is the same for the different standards.

Today there are commercially available databases with active features, i.e. active mechanisms are available for development of information systems. But the usage of active mechanisms is low in practice. This is due to the insufficient methodological support in analysis and design for developing ECA rule based software. It has been proposed that one of the most suitable ways to tackle this problem is not to develop new methods but to extend existing methodologies.In this thesis an extension of the Object Modeling Technique (OMT) is developed, called OMT-A, which is able to model active rules.

AbstractBusiness, or business decisions always involves an endangerment from the company?s aspect, but when it comes to business with foreign countries the risk profile looks quite different from the profile the company has when its doing business inside the country. Therefore, it is extremely important for an export company or import company to carefully consider the risks that are enclosed with the deal, before he makes the decision to enter a deal. One of the most important risks a company have to considerate when doing business with foreign countries is the currency risk. A company is exposed to currency risk when either long-term or short-term changes in the exchange rate may affect the result of the company, competitive position and growth.

It is reported that adolescents' health is deteriorating, when their mental illness has increased. Adolescents' social conditions have also become worse. The mental illness is linked to the individual living conditions. The purpose of this study is to investigate which factors adolescents experience have been contributing to making a lifestyle change. The apparent factors can be used to promote adolescents´ health.

A vulnerable group in society is people with ASD (autism spectrum disorders) or autism. This group seems to increase, mainly due to genetic factors but also environmental problems. Medical research has accelerated in the U.S. and Europe. The biggest problem for people with disabilities is the inability to communicate, both verbally and socially.

Studien syftar till att erhålla en djupare förståelse om hur ordningsvakters uppfattningar om hur deras yrkes? och privatroll ser ut. Vidare är syftet att ta reda på hur våld och hot hindrar utförandet av en framgångsrik vaktroll. Metoden vi har använt oss av var semistrukturerade kvalitativa intervjuer med åtta ordningsvakter. Studiens resultat tyder på att yrkes? och privatlivet utgör två separata sfärer.

Lansen Technology is a security company from Halmstad, Sweden and their focus indeveloping and selling alarm solutions. One of their latest inventions is a vibration sensor thatrecognizes very small movements in the ground.The thesis work was made in cooperation with Lansen Technology AB and the task was toinvent a test equipment that decides whether the sensor is working correctly. By generatingcertain frequencies with specific amplitude, we will expect the sensor to give a similar output.The final report includes all the parts of our work as studying, choosing components,programming, construction, results and conclusion..

This thesis work is executed at Business Unit Ericsson Test Environment (BETE), in Linköping. BETE is the department at Ericsson, which is responsible for the operation and maintenance of the company's Operations Support System (OSS). Their management system was outdated and they wanted it to be updated and it also required new features. The database needed to be replaced and the data migrated to a new database without licensing costs. The system also needed a part where employees could manage existing users.As a programming language PHP was chosen for its dynamic possibilities, platform independence and good support for database intergration.

Motivation, in an organizational context, is about whether the employees feel that their work is worthwhile, satisfactory and that there are opportunities for further development within the organization. However, motivation can be affected by a number of factors that originate from the employees? characteristics, the characteristics of the situation and the individuals perception of that situation. A factor that could lead to a low level of motivation is if the employee feels that his work is monotonous.Thus the purpose was to study the factors that lead to motivation and job satisfaction in a working environment that generally is considered monotonous and dull by investigating the target group cashiers at two Swedish grocery stores called Ica Kvantum and Coop Forum.In this study a quantitative method was used by the design of a questionnaire. The questionnaire was used to get a general idea of the factors that the respondents consider motivating in their work.The results and the analysis of the questionnaire show that you really cannot make any general conclusions since there are many different factors that lead to motivation depending on who you are as an individual and in what phase of life one finds oneself.

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.

In this study we have analysed from an intersectional perspective two textbooks Historia 1b and Progress Gold A which are purposed to be used as teaching material in Swedish schools in the subjects of History and English. Our question and reason for doing the analysis is to emphasise and make the variety of women in the books visible in order to compare that variety to the one that is demanded by the Swedish curriculum. The analysis is made from an ideology critical perspective and contains quantitative elements. Our conclusion is that the material contains both excluding and including features. Some intersectional categories are well represented while others, like functionality and religion, are not.

When SKL (Swedish National Laboratory of Forensic Science) gets images to analyse, the task often is to identify a person or an object. In that work it?s important to find features. Unfortunately images from camera surveillances often contain a lot of noise, so details can be hard to discern.A simple method to improve an image from a sequence is to compute the mean of some of the images. However, the part of interest in the image has to be in the same position in all images.
