Communication is a part of everyday life. The more sensitive information we handle, the more interesting the question around security of your information becomes. There are two ways of handling security around the information you want to communicate, either you control the means by which you are communicating. Or you control the way you communicate, making you able to use existing communication channels. Existing methods within cryptography enables two parties to communicate information securely.

The aim of this study is to describe, from a didactic point of view, wether gender norms are challenged and sex equality is maintained when two teachers in grade one communicate with their pupils. This is based on the existing norms in our society which generates into certain expectations of how one should act depending on wether you are a girl or a boy. In addition to this, the lack of equality between women and men is a global question. The norms and conditions in society are reproduced, but can also be deconstructed in school (Martinsson and Reimers 2008, p. 8).

The purpose of this report is to evaluate different methods for identifying states in robot models. Both linear and non-linear filters exist among these methods and are compared to each other. Advantages, disadvantages and problems that can occur during tuning and running are presented. Additional measurements from accelerometers are added and their use with above mentioned methods for state estimation is evaluated. The evaluation of methods in this report is mainly based on simulations in Matlab, even though some experiments have been performed on laboratory equipment.The conclusion indicates that simple non-linear models with few states can be more accurately estimated with a Kalman filter than with an extended Kalman filter, as long as only linear measurements are used.

In this master?s thesis the problem of simulating conditional Bernoulli distributed stochastic variables, given the sum, is considered. Three simulation methods are considered, namely the acceptance/rejection technique, Bondesson?s method and the Markov chain Monte Carlo method.To compare the three methods the bias and the standard deviations of the simulated variables are evaluated. The results of the simulation study shows that the Markov chain Monte Carlo method is not the best method for this type of simulation.

Aeroseum is an aviation museum located in an old military underground hangar. The ventilation system in the hangar is designed for the military purpose of the hangar. This design includes a solution with air flowing through the space between the construction of the hangar and the rock surface. The solution is intended to avoid a buildup of inflammable gases. This design leads too high humidity levels in the hangar.

ABSTRACT This essay is about traffic analysis of Web servers. The purpose is to investigate if companies analyse the traffic on the Web server and if they use this information to create more than simple statistic reports. The questions that we will answer are the following: ? How common is traffic analysis on the Web server among companies? ? Is the Web administrator limited in analysing the Web traffic, if the company has the website on a Web hotel? ? Does the company uses the results they get from analysing the traffic on the Web server for updates and changes on the Web page? To answer these questions we made a questionnaire investigation by telephone interviewing the companies? webmasters. The extent of the investigation was 20 companies in Blekinge. The information we gathered from the investigation showed that it is becoming more common that companies analyse the traffic on the Web page and that they uses the information to more than statistic reports, for example updates and changes of the Web page.

In Sweden we have a regulated gambling market which means that there are three gambling companies who are operating under the supervision of the Swedish state. These companies have exclusive rights to the Swedish market, divided between them. AB Svenska Spel is one of them and they control all gambling concerning sporting events and the four casinos in Stockholm, Gothenburg, Malmö and Sundsvall. However, since a few years back several Internet-based companies have entered the Swedish market and the competition has become even fiercer in the last years. Due to numerous marketing restrictions the Internet companies have been forced to find new ways to strengthen their brand.

Gotland is famous around the world for its unique nature. The agriculture here has always been an important source of income and part of the identity of the island. But today the profession has low status and hard to survive. How can the interest for farming be increased?Gotlandsgården is an investigation about how the agriculture could develop.

Operators and Internet service providers invest in broadband to be able to deliver new services that require higher data transmission rate. A way to make this possible is to use ADSL, Asymmetric Digital Subscriber Line, as the access technology. To be able to handle this technology, the service providers should do a pre-qualification. Methods and tools are needed to analyze the local copper lines and decide if these qualify for ADSL with respect to service availability and possible bandwidth through the lines. This report brings up some methods for pre-qualification of ADSL, the important quality parameters and how to gather them from the available services today.

This thesis shows the result from investigations of methods that use distance vectors when matching pictures. The distance vectors are available in a distance map made by the Euclidean Distance Transform. The investigated methods use the two characteristic features of the distance vector when matching pictures, length and direction. The length of the vector is used to calculate a value of how good a match is and the direction of the vector is used to predict a transformation to get a better match. The results shows that the number of calculation steps that are used during a search can be reduced compared to matching methods that only uses the distance during the matching..

The purpose of this paper is to investigate contents in the news in order to search for similarities between the two television news reports, Rapport and Nyheterna. The news features that I examined in my investigation were broadcast in April and May 2006.SVT and TV4 are two Television channels both belonging to the analogue television network in Sweden, which means that they reach out to almost the whole country. Hence I thought it was interesting to investigate their reports on similar news.The question:- Which are the similarities and differences between how the two programmes describe their reporting on similar news?When I put together the information from the two programmes in the schedule I based my analysis on the following questions: topic, place, length, type of reporting and per-sons/sources.The method for this investigation is a quantitative content analysis. However, some part of the collection of information and description/interpretation of the material is qualita-tive.Rapport and Nyheterna had an average of 15 similar news features per week, of which foreign news dominated.

The setting of pupils' final grades in the Swedish upper secondary school system is the responsibility of their teachers and once grades are set, they are not open to appeal. This can be compared with the British system where an external, central examination board sets the final grades based on the result of externally marked examinations (A-levels). These grades are then open to appeal if it is felt that an injustice has been made.This research paper has been an investigation into how pupils in one Swedish upper secondary school attempt to influence their teachers in the grade-setting process and how these teachers are affected by these different methods. Five teachers in total were interviewed in a qualitative case study. The study has also taken up the controversial issue of how grades, which are set individually by thousands of teachers across the country, can be deemed to be fair and equivalent.The study revealed that pupils employ many different methods when trying to influence their teachers in the grade-setting process e.g.

Mould is a common contamination in cereals. The growth of mould can stimulate mycotoxins production andsome of which at critical concentrations cause health problems in humans and animals. Fusarium is one of thefungus species that has been found in crops and can cause major problems for farmers such as reduced harvestand economic losses. A group of Fusarium species, Fusarium avenaceum, Fusarium poae and Fusariumtricinctum express a mycotoxin, enniatin. The limited information available today about enniatin-forming fungiis that they grow out on fields of wheat in colder climates.

Introduction: In this investigation I have illustrated, teacher treatment in a mono-cultural pre-school class and in a multicultural pre-school.Purpose: The purpose of the study was to illustrate how educators go about it when they face bilingual children to see how they work in a comparative perspective. The purpose was answered, based on four questions relating to how teachers relate to the meeting with bilingual children, the approach teachers use, which operation mode the use, if the take advantage of children's traditions, and if there is any different in the teachers? treatment of bilingual children in the mono-cultural pre-school class and in the multicultural pre-school.Theories: The theory is linked to the concepts like operation mode, inter-cultural approaches and communications.Methodology: The used methods are qualitative interviews with four pre-school, teachers where an interview guide with formulated questions and observations were used. The purpose of the working methods was to highlight teacher treatment of bilingual children to discover different approaches to meet the bilingual children.Conclusion: The study has shown that the multicultural pre-school working inter-culturally, they are taking advantage of children's home language that is lifted in the nursery and the children's background, while in the mono-cultural pre-school class, they meet bilingual children foremost to develop the Swedish language and they also show interest to the children's traditions. Teachers? treatment leads to a growing confidence in the children and knowledge for the cultural background..
