This thesis lays the foundation of the future routines of effective error repotring fortraffic devices in the raiway sector.If a device, for example a timetable display, stops working it is vital that the device isfixed as fast as possible so that the travelers dont miss any important information.The methods that are used today are old and not very effective. It can take time forthe repairmen to find the right device or locating the broken component. At the sametime he is supposed to maintain telephone contact with central control throughoutthe whole session.The need for a new, more effective, system is vital to make the whole repair pfocessmore effective and let the repairmen work without having to contact the centralcontrol by phone.I started this work by examining the possibilities of assigning every object with aunique identifier (ID tag) that could be accessed by a manual scan device. The ideawas that the ID tag could holw information about the object and be obtained byscanning the ID and get the information presented on a mobile device.The work also included building a internet application that enabled the reader to seeand change the information on the ID tag.The result was a database that stored information of different objects which could beobtained by scanning the ID tag and presented by a internet application..

The development of applications for mobile devices has exploded in recent times. This has also led to the introduction of several new mobile operating systems. To streamline application development for multiple platforms, techniques have been developed to be able to reuse the same application regardless of the operating system. If the same application can be used on multiple platforms it will save both a lot of time and money. Today there are three types of techniques to develop an application; web, hybrid and native application, where the latter is specific to the operating system it has been developed to.

Denna rapport beskriver framtagande av ett koncept för ett geografiskt informationssystem som är anpassat för att köra på moderna mobila enheter ute i fält. Detta sätter krav på systemet vad gäller beräkningskraft, lagringsutrymme samt möjligheten att klara av intermittent datakommunikation. För att ta fram systemet utfördes först en förstudie med databaser och sökmotorer användes för att hitta relevant information och relevanta artiklar som kunde hjälpa till vid framtagningen av systemet. Denna fakta tillsammans med utförda tester och ?trial-and-error?-programmering ledde i slutändan till ett koncept som klarade av de krav som ställdes på systemet.

This thesis is basically a design project aimed to find a safe and reliable automatic safety device, which is designed to be suitable for highly automated industrial situations.

All human beings need and have the right to a language. How a language is learned and used depends on the individual conditions. This study considers the work to development the language done by pedagogues in a special school for mentally retarded children. How do pedagogues work to develop the language in children who are so different and have so different conditions and needs? That is the central aim of this study.

The purpose of this study was to investigate how social services workers describe, the risk of being exposed to threats and violence in their profession. Six social services workers were interviewed, four from the Welfare Office in a major city and two from the Child and Family Services in a minor city. Results showed that the majority of social services workers consider themselves exposed in their profession, meaning that they feel there's a risk of a violent or threatening situation occurring in their work situation. All interviewees had experiences from some sort of threat or violence in a work related context and they attested that non-personal assaults, such as threats made through telephone, email and answering machines are more common than verbal assaults made in personal meetings. Being prepared and listening to ones intuition is a way of dealing with exposure when meeting with a client.

This Bachelors exam is about young adults and their use of Mobile Social Network System.The use of mobile social media has become more common in today?s society, ranging fromteenagers, the dominating internet users, to the elderly. The traditional purpose of use inmobile phones, the voice communication from one place to another, has in Sweden beendominated by text communication instead. Along with the development of Smartphones andthe mobile interface, the births of mobile social media have increased in the market.Reports have shown that of all the devices with the possibility to connect to social networks,the one kept closest to our bodies is the mobile phone. One of the advantages of using thephone for mobile social media is that you can easily and smoothly update whenever andwherever, within one arm?s reach.

The focus of this study is children´s influence and participation. This is an important part of preschool, according to the Swedish curriculum (Skolverket, 2010). Hoping to see another perspective of working with children´s influence and participation, my study took place in Nepal. The method used for this study is qualitative interviews. The interviews are made with teachers with insight in preschools in Nepal.

Every year, approximately 700 000 individuals´ visit an emergency ward in Sweden as a result of injuries and to the emergency ward at Umea University hospital (NUS) about 12 000 injured arrive every year. This study is a retrospective cross-sectional study that surveys injuries caused by crashes among 153 pedestrians and 53 bicyclists, who have been injured in a geographically well defined area during the period January to June 2009. The aim of this study is to survey injuries among pedestrians and cyclists and to examine what preventive measures could reduce these injuries in the Umeå municipality. The results show that falls caused by slipper surface are common among both pedestrians (71 %; n = 109) and bicyclists (32 %; n = 17). Almost one third of the pedestrians (34 %; n = 43) were in the age of 65 or older.

The main topic of this thesis is to evaluate the impact on the usability of web pages when using responsive web design, a concept for developing web pages whose design adapts to the screen size being used. This is done by creating a responsive prototype based on an existing web site. A number of usability tests are conducted on the two versions of the site in order to compare the time to complete the tests and to observe the behaviour of the test participants. The tests are conducted on desktop as well as on mobile devices with varying screen size.The number of test participants was relatively low, and so the quantitative result is not statistically valid. However, the conclusion is that the most effective combination is to use either of the sites on desktop format.

The aim of this thesis was to investigate how students, teachers and special teachers use, or may want to use, mobile phones as a resource in everyday schoolwork. An analysis of the result was made base on two main theories. One i Säljös theory about the sociocultural perspective, where artefacts play an important part in the devolopment of human society. The other is Laurillardss thougts of social learning and the use of technology in teaching. The methods used were inquiries and semi-structured interwiews with individuals and groups.

Music has always been an important form of communication and it can be found in many different contexts including aesthetical, cultural and emotional forms. In the globalized society of today music can be distributed fast through radio, TV, CD: s and the Internet. For many people consumption of music is an important part of the daily life and it can contribute to shape an individual?s attitudes and personality.The main purpose of this study is to find out whether there are any differences between men and women?s musical preferences. I will apply an explorative approach using qualitative interviews to describe what causes the differences.

With the purpose of finding the motives behind use, production and reuse of Open Educational Resources (OER), the writer has conducted a qualitative survey. The three main questions in this two years master?s thesis are:? Why do people use others? unmodified OER?? Why do people produce OER?? Why do people alter and reuse OER?The theoretic framework is built around Manuel Castells? network society, with its social and efficiency seeking dimension, along with the Knowledge commons. Some pedagogy is included as well.A web survey was distributed to 796 users of the Connexions OER repository. 95 responses were received.

The aim of this master?s thesis is to obtain greater understanding of how children relate to the film medium and their experiences. This is obtained by listening to the children and observing their verbal and nonverbal communication in two focus group interviews. Children?s access to and selection of film are due to adult?s restrictions.
