The objective of this work was to evaluate and implement a number of energy saving functions for a specific embedded system. The functions were then grouped into a number of energy levels with known properties in terms of functionality, energy consumption, and transition time between the levels.The embedded system consisted of an AT91 ARM9 processor, GSM/GPRS modem, display, Ethernet and other peripheral units. Some energy saving methods that were considered were suspend to RAM, suspend to disk, frequency scaling, and methods for saving energy in the modem, Ethernet, USB and display backlight. The functions were grouped into levels and an interface was specified for controlling the energy level.It proved possible to get known properties within the defined energy levels, even though the paritioning of functions into these levels proved to be sub-optimal in a typical application usage scenario because it was designed for mainly energy consumption, not usage.The final result is a number of energy saving functions grouped into levels, which are controllable via an application interface. Each of the levels have a known energy consumption in both loaded and un-loaded mode..

Syfte: Att klargöra vad det finns för likheter hos de nyheter som publiceras av privatpersoner på sociala medier för att sedan plockas upp och bli till nyheter i de traditionella medierna.Metod: Kvalitativ forskning.Material: Fem nyheter som skapats av privatpersoner och publicerats på sociala medier och sedan plockats upp av traditionella nyhetskanaler.Huvudresultat: De fem fall som studerats i denna uppsats indikerar att man som medborgare, med rätt sorts materiellt, kulturellt och socialt kapital, i vissa specifika fall, har möjlighet att påverka den traditionella nyhetsagendan genom att publicera text eller video på sociala medier..

Through earlier research it has been established that more and more readers are turning to social media in their search for everyday news. In this report we zoom in on news concerning football and try to find out how readers reason in picking their sources, whether it is social, online or traditional media. By interviewing a group of six, all interested in football and active within social media, we have seen that allthough social media is becoming a major influence in news reporting, it does not seem to be competing with traditional online media. Instead the two are offering the readers very different things all together, and theese differences are what we try to show in this report. Our hope is that the research in sport journalism can be translated in to all kinds of areas and be an indication on how journalism and our society is evolving online..

Our premiss in this study is the escalating competition in the swedish newspaper market, which have become an issue regarding smaller editions for the newspapers, and some scientist have claimed that this has brought an sensational touch to their news. With this in mind, we have studied if a sensational touch is brought to the two biggest Swedish newspapersAftonbladet?s and Expressen?s first pages. Our purpose with the study is to look into the newspapers development regarding a more sensational newsworthiness on the front page over time. The use of quotes, images and news themes is indicators to measure the development.Trough a content analysis from three different years, 1972, 1992 and 2012 we have measured the data with the computer program SPSS.

Uppsatsens syfte är att studera skillnader mellan kultur- och sportjournalistik för att kunna undersöka vad dessa skillnader har för grunder och betydelser för vår uppfattning om kultur och sport i samhället. Varför låter sport- och kulturjournalistik så olika? Vad har det för betydelse? Genom att detaljstudera två av Sveriges Radios nyhetsprogram, Kulturnytt och Radiosportens nyheter, görs skillnader mellan de två genrerna tydliga och konkreta. Skillnaderna analyseras utifrån begrepp som genre, hegemoni, dikotomi och uppdelningen mellan hög och låg samhällelig status. Uppsatsens slutsatser är att uppdelningen mellan sport och kultur hålls stabil genom journalistiska genrer, vilka i sin tur är skapade efter uttryckens olika samhälleliga status.

This project investigated the current market regarding wireless net and the communication between the tools used for diagnostics/maintenance and an embedded system. Based on documentation obtained through interviews a demo system was created based on Bluetooth Low Energy (BLE) communication between an embedded system and an Android device.This report intends to describe the tools and methods used in the design of the demo system and the result of an analysis of the BLE communication.Bluetooth Low Energy is an exciting protocol with wide applicability within the industrial field. This project investigated the communicational possibilities between a Smartphone and a Raspberry Pi and based on the results that emerged the conclusion can be drawn that BLE is a protocol with many beneficial applications within industrial IT..

Journalists´ role in society has traditionally been of representative nature with a task to distribute news and scrutinize those in power. But technological changes have created a new publishing world outside the traditional media institutions. In today?s redactional society anyone can become a publisher in a blog or through other channels on online. This process can be seen as contributing to increased democratization giving everyone the opportunity to publish.

This report presents a master thesis project performed at Elekta AB during the fall of 2013 and early 2014. Elekta is a medical technology company and their main product in the Stockholm office is a gamma knife used for radiosurgery. The gamma knife contains a cluster of a dozen motor servos and motors used for adjusting the patient and the radiation sources over a CAN bus. A self-developed hardware-in-loop simulator running on a PC with LabVIEW is currently being used for integration level testing of the control system of the gamma knife. The simulator has some problems with it not running in real-time and having other performance issues.

This is a qualitative study of how some journalists on the Swedish national media are using social media in news work. The study, carried out by using interviews, also covers how these journalists' work is influenced by social media. For the journalists in the study social media has become a tool to do research, get news ideas and find interviewees. At the same time social media affects the work of the journalists, as the social media increases the speed of news and flow of information. Even though they involve some challenges, social media facilitates news work and the journalists in this study have a positive attitude towards the phenomenon.Keywords: Social media, news journalism, the national media..

The study - Hur skapas en journalist? - examines why so many people choose to turn tothe journalist profession when the conditions for a secure position on the labor market ispoor. The study also highlights how recently graduated journalist perceives their temporary and insecure position on the labor market.The study was performed trough ten biographical interviews with recently graduated journalists. Via the interviews I examined what has formed the individuals to perceive journalism as a rational or pragmatic choice for a career. The study shows that journalists, who come from families with high cultural capital, have been shaped by a particular culture of education, which focuses on education as a step towards selfrealization.

Minimizing power consumption is a critical part of many embedded design projects. Thechallenge is to limit the power consumption of the system and at the same time providesatisfactory service to the user. With regards to microprocessors, the main way of limiting powerconsumption during program execution is to adjust the frequency and the voltage at which theprocessor operates.To enable the implementation of real-time scheduling with support for dynamic voltage andfrequency scaling, an exhaustive study of the Freescale i.MX31 embedded microprocessor isperformed. Specifically, the power consumption relationship to all relevant frequency andvoltage settings is investigated. In addition, to enable frequency and voltage scaling in a real-timeenvironment, a complete timing analysis of proposed voltage and frequency scaling methods isperformed and their suitability for use in real-time systems is evaluated.To integrate voltage and frequency scaling capability into OSE RTOS, a software module hasbeen developed for this operating system.

In year 2000 the Swedish Public Service television started a new series of programmes named Mediemagasinet. The purpose was to expose the work of journalism through the eyes of a journalist. The programme showed different types of tasks and problems that have to do with journalistic reporting. The form of Mediemagasinet wasn?t anything new but the content was presented as the very first of its kind.

This study examines from a gender perspective how the gender distribution is viewed in the content of Göteborgs-Posten's sports pages and the short and long term effects of the the newspaper's gender equality plan that was introduced in 2005. It is a quantitative study for two sample periods, 2005 and 2009, that investigates how many articles in the newspaper which is about women's sports and male sports. Michel Foucault's theory of discourse is central to the study, his view of identity in society and how these are represented fit well on gender issues in sports journalism. The results show that women's sport is greatly subordinate to man's sport in terms of number of articles. The gender equality plan has not had any noticeable effects on Göteborgs-Posten's sports pages. This is due to a variety of factors ? economic aspects weigh heavily in this problem. .

Computational techniques have transformed the journalistic approach. Journalists now have the opportunity to integrate user-statistics from the news website with their work. Singer (2011) argues that journalists seem particularly afraid of items, which they perceive as trivial or otherwise unsavory, will prove popular - potentially creating management pressures to produce more of those stories. She describes this practice as ??traffic whoring??.
