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.

This report describes a study of two different methods to achive the best possible result in setting out apartment details. These two methods are the setting out of details with a measuring tape from baselines and the setting out procedure with an instrument (totalstation).Through our knowledge in surveying and mapping technology and help from a carpenter, this investigation has been implemented. The setting out using a tape has been performed by letting the carpenter to set out windows, bathroom and water- and drain-details from baselines and drawing. The setting out using a surveying instrument was carried out by means of a Trimble Total Station. These two methods have been compared in order to detect and show the difference that occurs.The report shows the investigation background story from the practice of Swedish Mätcenter in Karlstad.A result of differences in accuracy and time is described in the report, as well as their theoretical consequences.

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.

This study examines the cultural place and status of video and computer games in the Swedish public library. Using works on popular culture and the theories of Pierre Bourdieu, this study employs quantitative methods, as well as textual analysis, to analyze the results of an online questionnaire with 19 questions focusing on selection criteria, shelf placement, perceived competence, as well as reasoning for having or not having these games in the library. 286 out of the 440 libraries contacted is participating in the study, and the libraries consist exclusively of public libraries in Sweden that are found in the database of the Royal Library.The results of this study show that a larger number of libraries than previously indicated have started to provide electronic games to their patrons. At the same time, patterns in the data and comments suggests that these games in many cases still do not enjoy the same level of cultural recognition as other media. Indicative of this is the way most libraries seem to focus on the medium being exclusively for their young patrons, with seem-ingly very little in the way of investment for adults.

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..

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.

This thesis studies the customer relationships and customer accounting methods used by a Swedish fashion company. The aim is to test the empirical applicability of the relationship based framework developed by Lind and Strömsten and to explain potential differences between empirical observations and theory. The framework is based on the categorization of four customer relationship groups and the appropriate customer accounting methods to be used for each relationship. The fashion company, that recently assessed the profitability of its customer base in an aim to implement a new customer strategy, is the object of the qualitative case study. The case study reveals that all customer relationships are to be found at Whyred, except the connective customer relationship.

Total organic carbon (TOC) and chemical oxygen demand (COD) are two methods used for measuring organic pollutants in wastewater. Both methods are widely used but the COD method results in production of hazardous wastes, including mercury.The purpose of this study was to validate the method TOC that will replace COD and find a factor to convert TOC to COD. In this study 26 samples were analyzed from four sewage treatment plant in the municipality of Enköping.The results show that the COD method could be replaced by the TOC method.The factor for COD/TOC was between 3.1 - 3.3. Both methods will be used in parallel until 2013 when it will be forbidden to use the COD analysis..

Abstract People who have problems with the written language will face serious difficulties in todays society. Our social structur is based on the criterium that every individual has to be able to read and write, and for this reason it is important that pupils with learning difficulties receive help. The purpose of my investigation is to examine how children with reading- and writing difficulties can benefit throught creative methods. Children with reading- and writing difficulties are in need of these creative methods that exist today. Amongst all of our public healht issues, dyslexia is one of the biggest problem we have today and children are therefor in need of these creative methods. Through  qualitative interviews with two educationalists there has been established thad the creative way of working benefits children in many ways if it is preformed correctly.

Ericsson har utvecklat ett ramverk för multimediakommunikation som heter Mario. Mario kan användas för att sätta upp video- och ljud-samtal över IP och finns fungerande på Android och iOS. Mario är en del av web browsern Bowser som finns att hämta på Google Play eller App Store. Bowser möjliggör att köra WebRTC applikationer skrivna i HTML5 och JavaScript på Android och iOS.Nu när Microsoft släpper sina nya plattformar, Windows RT, Windows 8 och Windows Phone 8 så finns ett intresse att försöka flytta detta ramverk till dessa plattformar. Vi kommer göra ett försök att porta Mario till Windows RT.

How does IT-consultants reason in their consulting process regarding the development of a clients IT-based internal recruitment system? The purpose with this paper is to investigate how an IT-consultant is reasoning in a consulting process and investigate whether consultants are using established models and methods in their work. We have chosen to work with a qualitative examination to attain our purpose. In our work gathering the empirical facts we have been working with a case study, an observation and a simulation exercise. The combination of these has made it possible to carry out the paper and produce the most correct data possible. Conclusion: We state that IT-consultants do not use any theory-based methods, they use process methods created by themselves and their company.
