Journalistrollens rivaler : Om public service-reportrars syn på sin roll i relation till användarskapat innehåll och medborgarjournalistik

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.

Implementation of an FFT algorithm using a soft processor core

This report deals with the modeling of a part of the communication system based on the IEEE 802.11a standard which represents the next generation of wireless LAN with greater scalability, better interference immunity and significantly higher speed, up to 54 Mbps. 802.11a uses Orthogonal Frequency Division Multiplexing (OFDM) where modulation is performed by an IFFT and the demodulation by an FFT. After modeling the FFT in Matlab and C, the FFT implementation has been validated using a soft microprocessor core by Xilinx (Microblaze) and the results were compared..

Systemidentifiering och reglering av en luftningsbassäng på ett reningsverk

A wastewater treatment plant has the task to refine the wastewater from substances that should not be released into the environment. The decomposition process can, in a simple way, be described as follows: micro-organisms breathe oxygen and eat unwanted substances. The environment in which the micro-organism lives is known as sludge and the correct amount of oxygen available in the sludge is important for the decomposition to be effective. The oxygenation of the sludge alone stands for about 30% of the plant?s energy consumption.

En studie av miljöfaktorers betydelse för förekomsten av Francisella

This thesis aims to analyse relations between the risk of Francisella in endemic areas and environmental variables. The thesis also discusses relations between occurrences of Tularemia and meteorological factors. The analysis resulted in several significant models that explained the occurrence of Francisella. These models can however only be applied to the year 2004 since there were too few test performed the other years, therefore no comparisons could be made. Another conclusion was that the relative humidity was significally higher in the year 2003, the same year as the occurrences of Tularemia was at its peak. .

Artificiell Insemination (AI) hos hund : en sammanställning över användandet av seminering inom hundaveln i Sverige under åren 1995-2004

The use of artificial insemination (A.I.) as an alternative to normal mating in dog breeding in Sweden are controlled by regulations from the Swedish Board of Agriculture and by ethical rules assigned by the Swedish Kennel Club. Only veterinarians, who have a specific certificate and are specially trained and educated, are allowed to perform inseminations in dogs. Each artificial insemination must be documented and reported to the Swedish Kennel Club (SKK) which, on the behalf of the Swedish Board of Agriculture, yearly presents statistics concerning the use of A.I. in Sweden. The objective of this study was to illustrate the use of artificial insemination in dog breeding in Sweden for the last decade, using the yearly reports from the Kennel Club during the period of 1995 to 2004.

Development and evaluation of environmental enrichment for captive Humboldt penguins

Environmental enrichment is of high importance for zoos. Borås zoo asked SLU (Swedish University of Agricultural Sciences) for a student to perform a bachelor thesis for them. The task was to develop and evaluate environmental enrichment for their Humboldt penguins. A structure was made, consisting of a sinking skeleton with a floating bridge attached to it. It was presented in an area of the pool that the keepers had experienced that the penguins did not use to any extent.

Användarcentrerad Systemdesign

This essay focuses on the term usability while conducting a user centred system design. Usabilitymeans to what extent a user can use a product to achieve effectiveness, efficiency and satisfaction.Development using a user centered system design means that knowledge about the end-users andit?s opinions becomes a crucial part of the development process. The question of this essay is if usinguser centred system design will lead to good usability.We used methods from a user centered system design point of view while developing an applicationfor a Swedish bookstore company called Bokia AB. This included user and task analysis following by aclose relationship between the developers and end-users by using sketches and showing themprototypes of the system while collecting feedback.After concluding our case study we determined that using methods from user centered systemdesign could be used as a great tool to further improve the usability and to improve an applicationssuccess chances..

Könsskillnader i betyg, Ronneby kommun -Ett implementeringsproblem?

This study was carried out in Ronneby municipality during May 2006. I chose to compare three senior schools with regards to the implementation of objective orientated directives based on the teachers understanding of the task, motivation, resources allocated and their significance for the disparity between boys? and girls? grades.I carried out nine in-depth interviews: three at each senior school. From the interviews it emerged that teachers perceive objectives differently from parents and students. Teachers claim that they understand the directives but say that they lack the resources.

Den som hoppar högst är bäst? : En kvalitativ intervju-studie om gymnasieelevers uppfattningar om betyg och bedömning i idrott och hälsa

abstract buzz marketing, the phenomena Have you ever thought about why the small French pastries called macarons suddenly became so extremely popular? Soon they were seen everywhere in the media, on every celebrity party and shortly after of course on every Swedish person?s cake dish. Could it be that a trendy it-girl happened to mention these lovely creations in her blog?What (or who) is it really that decides and controls what is popular and what is going to sell? If one individual can influence a whole group of followers it is definitely something marketers should take advantage of. One cannot any longer rely on traditional advertising, one needs to be more creative and rethink the possibilities to get through the media noise.

LCC-kalkyler i byggbranschen : förutsättningar och tolkning av resultat

Background:Life-cycle costing (LCC) is an investment calculation that takes intoaccount operating costs throughout the investee lifecycle. LCC calculations are mainly usedto evaluate investments that have no revenue side. Attempts to apply the LCC calculations forbuilding-related investments have occurred since the 1980s. Despite the advantages ofusing LCC calculations, use has not passed through in full. The main obstacles have beenidentified as a lack of relevant input data, and insufficient experience of workingwith LCC calculations.

Energideklaration och energiförbrukning för småhus och flerbostadshus

Energy is today a very common topic, not only in Sweden but in the whole Europe. In EU they have given out a directive 2002/91/EG about buildings energy use and throw this they have forced their members to show how much energy their buildings use. In Sweden has the gouvernment established a law (SFS 2006:985) about energy declaration for buildings which demands that the building owner needs to show how much their buildings energy consumption are. Important to know is that this law doesn´t applies for industrial buildings.The report will show what the new law about energy declaration for buildings and appurtenant directions will mean for Riksbyggen. Also energy calculations will be done to be able to compare Riksbyggen buildings with the new law and directions.

Cykeltidsoptimering av sjuaxligt robotsystem

This master thesis studies how much the cycle time, i.e. the time it takes for an industrial robot to perform a given task, can be reduced if an extra degree of freedom (DOF) is added to the robot system. The extra DOF consists of a linear track, which is supposed to be used in an optimal way. The problem has been studied using simulations in the robot simulation tool RobotStudio. To be able to run an optimization in Matlab, with the RobotStudio simulation cycle time as the object function, communication between Matlab and RobotStudio has been set up with an interface written in Visual Basic.

Konstruktion av mutterdragare för stora moment

This degree project was conducted in collaboration with Gremo AB located in Ätran.The aim of the project was to develop a solution to secure quality and to help assemblingthe locknut holding the vertical hinge on the harvesters and foresters from Gremo.At this time the nut is assembled manually by the aid of an overhead crane. The nut istightened differently from time to time, and there was no specified torque to which it istightened. Another present problem was the locking washer which sometimes getsdamaged during assembly, when this happens the procedure has to be started over fromthe beginning. The current assembly procedure is very time consuming and lengthy forthe employees.Our task was to design a machine that could tighten the nut to a specified torque with amargin of error of ± 3%. The assembly procedure will be held simple and the timerequired at a minimum.The project started by developing several principle solutions, the one solution that bestmatched our specifications were developed to a primary solution.Today we have started manufacturing and assembling our prototype.

Att styra och ställa En styrningsstudie med ResursCentrum för kvinnor som fall

In 1994 it was decided that a new network based organizational model was to be initiated to face the problems of some of the gender inequalities in Sweden. The organisation structure was named Resource Centre for Women (ResursCentrum för kvinnor).This essay constitutes a qualitative case study of governing, with this organisation structure as my field of inquiry. My ambition has been to outline and explain what kind of governing has been used and how it works. I have also tried to identify potential changes of the ways of governing over time. To help me out with that task, I have applied a theoretical framework, characterized of a governance perspective, and have used terms as: governing with networks, partnership, projects and visionary government to interpret my empiric material.My result shows that there have been various changes in the ways of governing, from a more hierarchal government form of governing to a more governance based one..
