This Master?s Thesis deals with a special problem that may be of importance when planning a frequency hopping mobile communication network. In normal cases the Frequency Assignment Problem is solved, in order to plan the use of frequencies in a network. The special case discussed in this thesis occurs when the network operator requires that the frequencies must be arranged into groups. In this case the Frequency Assignment Problem must be solved with respect to the groups, i.e.

The aim of this Master?s thesis is to study the information needs of the homeless. The main focus is to investigate what kind of information needs that are to be found among the homeless and also how information is exchanged and shared by the group. Another aspect of our study includes the sources that are used to fulfil these information needs. The homeless use of the library, as one of these sources, is also examined.

In 2009 transgendered persons were included in the Swedish law against discrimination. Prior to the inclusion a commission made an investigation of the necessity of such change in the law and how it could be designed. This essay focuses on the discourses regarding gender that appear in the law and the report written by the commission. Using theories by Judith Butler and discourse analysis inspired by Norman Fairclough it identifies two main discourses regarding gender: a two gender discourse and a queer discourse. The two discourses meet in the studied material in an antagonistic way, a conflict that is solved by separating the two and making one part of the law focus on gender and one on transgender.

In Sweden approximately ten percent of all children grows up in a family where at least one parent is having an alcohol related addiction. Since 1998 the development of group activities for children in this situation has been immense. The aim of group activities is to break the child's isolation and make them feel that they are not lonely in their experiences, give them knowledge about addiction and relive the pressure of guilt and responsibility.In a comparative study we examined studied how two different group activity models one with the conception of illness and one without, use the children's network to support the group process. The aim was also to find each models definition of the "normal family", since we understood the groupactivity as a part in the normalization process. We reached our aim through interviews with group leaders and by literature studies.

Abstract. The trade in prostitution/sexual services is regarded as a major social problem in Sweden. The prostitutes are seen as a group of passive, neglected and exploited victims, subject to repeated and forced outrage. However, there exists a network of sexworkers who claim their free will in selling sex as a trademark. They describe themselves as active subjects with a business of selling sex out of free will.

In order to decrease the disturbance from a cable testing equipment, the company Ericsson Network Technologies in Falun determined to design a new series resonant test system with a lower frequency. The new equipment is of series resonant type with a system frequency of 500 Hz. This equipment consists of an inductor, a capacitor and a voltage source. The voltage source is the same as the old one, the cable acts as the capacitor but the inductor has to be designed especially for the new equipment. In this thesis work several air coil inductor types were examined.

The aim of this paper is to find an algorithm to establish and maintain a virtual enclosure around a mobile unit. The area may take any form and should be scalable up to and including national borders. The enclosure is managed on the mobile unit. The target system is Android. Smartphones, tablets and more recently, cameras is examples of mobile units.

The linear televison have dominated the supply of moving pictures, but this is about to change with the possibility to consume it via the Internet.I n this thesis we have studied how the two Swedish tv-network companies, SVT and TV4 are working with their web TV and if their online services have affected the linear TV. To limit the size of the study we chose two network companies that provide the most popular tv channels and web services in Sweden. To gather data from these two companies we conducted qualitative interviews with people at the networks. We came to the conclusion that SVT and TV4 doesn't find that their web TV services (called SVT Play and TV4 Play) are competing with the linear TV. They rather regard them as assets to broaden their services.

Bitcoin is a digital currency that is used by people all around the world. The goal of this paper is to give an idea about how much trust there is in bitcoin among its users. This paper has used an online survey aimed at bitcoinusers and a content analysis to collect data about this trust.The conclusions show that there seems to be some trust in bitcoin as a technology and this is based on that the users have a good understanding about how bitcoin works. They also share their knowledge about bitcoin to people around them. The trust between people in the bitcoin network on the contrary doesn?t seem as high because certain technological properties hurt this trust.

Use of computers and computer networks is nowadays a part of everyday life. You do not use them only at home when you sit at you computer, but you can use them all the time everywhere. This can involve everything from surf to any website when you are at home, to checking your email on your mobile when you are on your way to work. Most people do not think about how it really works when they try to access a web page by typing the address into their browser, but something that most people probably notice is how long it can sometimes take to access a web page.All items which are directly connected to the IP network have a unique IP address that is used to make it possible to communicate. The IP address is either a period separated sequence of digits representing 32 bits or a colon separated sequence of digits representing 128 bits, depending on whether the address is an IPv4 or IPv6 address.

Because social media is personal and reaches users directly, it has become an important means of communication for companies trying to reach out to their audience (Nygren & Wadbring, 2013). Especially the possibility of interactivity has been discussed as social media's big advantage. But how much two-way communication is actually possible on social media? This is a quantitative study that focuses on how Swedish Facebook users in the ages of 16-25 interact with companies on the social network. The aim was to contribute with increased information and knowledge about how the users mentioned above interact with the companies as well as how the users perceive the companies communication and presence on Facebook.

Near Field Communication, NFC, is a short-range wireless communication technology that enables data exchange between devices in a secure way. A NFC phone has the potential to enable the convergence of wallet, phone and keys, but as many other technological innovations, the launch is struggling. We have discovered that technological innovation is only the first step. For an innovation to be adapted, there need to be business model innovation too. Many actors form the ecosystem of NFC and the business model for each service is still an unsolved problem.

During the last years, the importance of sourcing in firms has increased. Globalization, fierce competition and an increased level of outsourcing are common explanations to why firms have highlighted the potential to realize savings and the value creation that the Purchasing department can generate. One trend that follows in parallel with globalization is an increased pressure from society on firms to take responsibility for the impact that its products and services have on the environment. This responsibility creates even more attention as outsourcing involves trade with suppliers in low wage countries, where the level of environmental and social responsibility is not always satisfying. The Purchasing department, the firm?s interface with suppliers should therefore, together with the firm?s Environmental department, play a key role in the firm?s contribution towards sustainable development.

The purpose of this essay is to explore the actor network of a high technology company in the textile industry called F.O.V. Fabrics. The background for doing this is a recent project, which we choose to call the Salt & Paper Battery Group, aiming to commercialize a newly discovered technology ? a battery based on cellulose from an alga. We start by examining a range of network theories in order to eventually shape a framework of our own.

IT is often seen as a solution to many problems concerning effectiveness in organizations. Information systems within the healthcare sector is often viewed as medical devices rather than just systems or services. These medical devices are thoroughly regulated by laws, standards and certifications. In this study I participated in an innovative project that aimed to bring new life and use to the old fashioned patient journal by giving it a visual representation through the use of an avatar. I aimed to study the effects of regulators connected with the patient journal as a source of information for the innovative project.
