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..

Syftet med arbetet var att ta reda på om den ökade tidsåtgången som parprogrammeringen leder till uppvägs av de fördelar som den genererar i jämförelse med enskild programmering där arbetet delas mellan två programmerare och sedan integreras. I arbetet presenteras resultatet från en enkätundersökning som sju personer från fyra olika företag i Sverige har besvarat. Samtliga personer som besvarat enkäten har arbetat både med enskild programmering och parprogrammering. Vårt arbete bidrar till forskningsområdet programvaruteknik som intresserar sig för mjukvaruutvecklingsmetoder. På senare tid har detta forskningsområde också intresserat sig för lättrörlig mjukvaruutveckling där utvecklingsmetoden Extreme Programming (XP) ingår.

This Masters thesis work describes a comparison between two different methods for estimation of the down channel (base station to mobile subscriber) in Wide-band Code Division Multiple Access (WCDMA). The first estimation method, Optimal Feed-forward Channel Estimation (OFCE), is a conventional method that bases the estimates on data that is known to both sender and receiver, so called pilots. The second method, Decision Directed Channel Estimation (DDCE), is an elaboration of OFCE. It also uses user data for estimation. Simulations show that DDCE, in comparison to OFCE, does not attain an improvement in signal-to-noise-ratio (SNR) for high bit error rates (BER).

This report describes the development of an application in collaboration with Designingenjörerna AB. The company has worked for a long time with a community platform and they required an application where users can create their own unique profile representations, called Avatar Creator. An Avatar Creator is computer based application, which makes it possible to create a virtual character. The problem area behind this is that, large websites require a lot of administrative work when people upload profile pictures on different community pages. They can contain abusive material or pictures of other people rather than those who created the profile.The questions in this report are, how can an Avatar Creator help user to get a unique profile of himself? What are the advantages and disadvantages of an Avatar Creator? How to create a user-friendly application?To understand how an Avatar Creator works and get ideas to create an application, exiting Avatar Creators were reviewed on the Web.Collaborative work with Designingenjörerna AB was done to pin down the requirements for the Avatar creator application.

The technological development contributes to an increase in advertising when it comes to media. Those who are working to develop advertising are constantly looking for new ways to reach consumers in unexplored contexts. Web TV is a relatively new technique that involves the distribution of television across the Internet. This study intend to investigate how users perceive advertising appearing on web TV, and contribute to the knowledge about how advertising adapt to new media. To reach the results of this study, we used quantitative data, collected in the form of web-surveys and qualitative data collected through semi-structured interviews.

The number of smartphones are constantly increasing, 2010 approximately 200 million unitswere sold globally and the figure is predicted to increase to 1 billion in 2016. The increased useof smartphones also carries many risks, for example many smartphones are connected to theInternet. This is a possible way for hackers to gain access to user devices. Smartphones are wellrepresented in research on its safety, while research on its use and users? awareness often leavesmore to be desired.

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.

A rhetorical analysis of the educational interactive film ?Riskprofilen?, produced by the Swedish Civil Contingencies Agency (Swedish: Myndigheten för Samhällsskydd och Beredskap). This essay uses the theories and methods of Procedural Rhetoric, as described by Professor Ian Bogost, and Visual Rhetoric, as described by Professor Brigitte Mral to analyse the interactive and visual component parts of the artefact, and compares them to the intended purposes of the artefact as stated by documents pertaining to its creation, found to be those of educating the public; marketing the agency; and driving traffic to its webpage. The artefact is through analysis found to fulfil the purposes of marketing the Agency and of likely increasing traffic to the website upon which it is hosted. Regarding the primary, educational purpose this analysis finds that the artefact does not teach a user the accident-avoidance strategies it claims to do, but is dependent upon further materials..

I ett franchisesystem blir kontrollen av hur varumärket sköts inte lika överblickbart för franchisegivaren, eftersom den dagliga verksamheten planeras och styrs av någon annan, franchisetagaren. Franchising har historiskt sett nyttjats mest inom detaljhandeln. På senare år har även tjänsteföretag insett fördelarna med franchising. Dessa har dock andra förutsättningar än traditionella varuföretag eftersom det är svårare att standardisera och mäta hur en tjänst ska levereras och hur den upplevs av en kund. På grund av detta blir det av yttersta vikt för tjänsteföretag i franchisesystem att upprätta fungerande kvalitetssäkringssystem så att varumärken inte missköts.

A large part of the Namibian low income population lack access to grid distributed electricity. This mean they are effectively shut out from basic functions such as lighting, information technologies and hygienic food handling. Hence, finding ways of providing affordable off-grid electricity is an important, not to say critical, task.This master thesis is an innovation and concept development project that has been carried out in cooperation with organisations in Sweden and Namibia. The purpose of the project has been to (1) develop a concept for off-grid electricity supply in Namibia and (2) to gain a deeper knowledge within the area of innovation and product development for the Base of the Pyramid population, i.e. the poorest, but largest, socio-economic part of the global population.Essential in this project has been to acquire user understanding and to identify user needs to create a foundation for developing the concept.

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..

In this Bachelor's thesis the result from a Delphi study regarding FRBR, performed by Yin Zhang and Athena Salaba in 2007 and published in 2009 ? What is next for Functional Requirements for Bibliographic Records? A Delphi study ? is analyzed by qualitatively interviewing professionals active within the library and information science field in Sweden. The results are compared and possible deviations and adjustments are illuminated and discussed. The purpose of the thesis is to determine the topicality of the Delphi study in 2011 from a Swedish perspective. Conclusions made from the thesis shows that the main areas are still the same, but adjustments regarding the relative order of issues might be needed; primarily a shift of focus from theoretical to practical issues.

The aim of this paper is to investigate who the visitors are at a children's department at amain library in a larger municipality, and for what purpose they use it. We discuss: Is therea difference between various user groups, and if so, how do they differ'? Which library rolesdoes the children's department have? Does the children's department serve as a local libraryfor those who live in the immediate surroundings or as a main library for the whole municipality?The paper is based on a user survey performed in the spring of 1996 at the City Library ofGothenburg. 417 visitors and five staff members were interviewed.The children's department is used by various groups of people, from young children to seniorcitizens. The library roles are, among other things, an independent learning center and formaleducation support center.

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.
