Safe operation of a large synchronous power system as Nordel is not an easy task.There are several aspects to take into consideration. This thesis focuses on the problems due to voltage collapses in a transmission system.The ability to foresee an upcoming collapse is vital to maintain stable operation of the grid. The grid operator at Svenska Kraftnät (SvK) uses the computer program SPICA to predict the maximum transfer limit at specified transfer sections. SPICA uses actual states from the grid to predict the transfer limitation, and a quarter later a renewed estimate is produced and so on. This means that the operator can se his transfer limits vary every fifteen minutes.Our task in this project is to validate the accuracy of the limitations obtained by SPICA.

The focus of the thesis is: how conditions for agriculture in the Republic of Macedonia today may form the basis for development of the agricultural sector towards conditions needed for future accession into the European Union. The method for investigating this question has been to look at newly available farm monitoring system (FMS) data from Macedonia. Also to look at the latest government policies created in the country for the agricultural sector and rural areas in relation to the requirements for EU accession. Articles and empirical studies published by other authors related to the questions which arise in this study have been reviewed and presented herein. Trade relations, trade patterns and national economic and agricultural trends are displayed to provide a background overview for the study of the agricultural sector.

Twice as many women as men suffer from mental ill-health. The negative trend of mental problems among teenagers continues. In certain places in Sweden, 40 per cent of the teenage girls have outspoken symptoms of depression. This is why it is important to observe mental ill-health in a public health perspective. One effect evaluation of the DISA method (Depression In Swedish Adolescents) drew the conclusion that this universal depression preventive method is well working. The DISA method includes cognitive behavioural techniques that change negative pattern of thinking, give practice of communication, strategies of problem solution plus exercises to strengthen the social network.

Efterfrågan och tillhandahållandet av platsberoende tjänster blir allt större vilket i sin tur skapar intresse för billiga och skalbara tekniker i alla möjliga olika miljöer. Särskilt intressant blir tekniker som är lätta att installera på nya platser och vars hårdvarukomponenter är enkla och billiga. I denna rapport presenteras en experimentiell systemteknisk metod för positionsberäkning i inomhusmiljöer, specifikt de som på grund av lokala elektromagnetiska fält, rörliga större föremål eller oregelbundna ytor skapar störningar som gör det svårt att utföra förlitlig positionering. Systemet utgörs av ett antal wifi-routrar samt en signalmottagre kopplad till en dator med systemets mjukvarukomponent installerad. Resultatet bedömdes utifrån en förväntad nivå av korrekthet, närmare bestämt att minst hälften av systemets bedömningar inte har fel med mer än två meter, samt en övre gräns på högst tre meters fel i minst 90 procent av fallen.

Songs from the Crypt: Mapping the Forces that Hinder the Digital Revolution of Music Distribution This paper seeks an explanation to the low market share growth of the commercial digital music distribution in Sweden. The analysis identifies a spectrum of obstacles that hinder the digital distribution technology from becoming the main form of music distribution in Sweden. These obstacles make the digital music distribution less favourable in comparison with physical distribution from the consumer?s point of view. The authors suggest that in order for the digital distribution of music to become competitive the digital product would either have to be developed further to offer more customer value or the so called a là carte retail model would have to be replaced by a subscription-based distribution model.

In this essay the aim is to look at difficulties in preservation of buildings in general, andespecially the ones of the modernist era. To navigate in this huge field the study is narroweddown to take place in Finspång, a small Swedish town. In Finspång there was a swimmingpool facility built in 1967. In 2003 the facility was closed down due to its unusable conditionsand then after seven years with discussions of different plans about what to do with thefacility it was demolished in 2010. This case is the base in the essay, and why it was notpreserved.The purpose of this essay is to look at what the people in Finspång think about preservation ofbuildings with the demolished swimming hall facility as base, and what impact materiality hason questions regarding preservation, cultural heritage, memory and history.

Transmission of reactive power is well known to cause active power losses. Thus, newcomponents who can help minimizing these expensive reactive power flows are ofgreat interest to the power distribution companies. ABB Corporate Research hasdeveloped the first electronic power breaker. One possible application for thisbreaker is transient-free switching of capacitor banks. This could prove a usefuldistribution voltage complement to the switch-sync technique, mainly applied to transmissionvoltage level.

Som många andra IT-företag jobbar EVRY One Eskilstuna med nätverkssäkerhet. Detta område är komplicerat, omfattande och väldigt brett. Mitt uppdrag var att undersöka de olika nätverksattackerna som kan drabba ett företag. Vilka råd som finns för att skydda sig mot dem och jämföra dessa mot deras befintliga skydd. Syftet med denna rapport var att skapa en helhetsbild gällande nätverkshot och olika sätt man kan skydda sig mot.

Bakgrund: 2010 presenterade SCB en undersökning om hur 403 000 jobb tillsattes (GP2010). 79 000 av dessa tjänster tillsattes via personliga kontakter och ytterligare 100 000där arbetsgivaren själv kontaktade den arbetssökande. Denna trend i användandet av detsociala kontaktnätet får stöd av Lena Hensvik, doktorand i nationalekonomi, i tidskriftenFramtider (2012). Hon skriver att den sociala omgivningen såsom grannar,skolkamrater, tidigare kollegor och föräldrar har stor betydelse för hur vi får anställningeller inte. Hon menar att kontaktnätet är en viktig självinvestering då vårdandet av ensnätverk uppenbarligen kan underlätta jobbsökandet.

Bakgrund: Det finns många olika sätt att marknadsföra sig på idag. Det kan exempelvis vara via sponsring. Sponsring är en markandsföringsform som ökar för varje år trots att forskning tyder på att det fortfarande är svårt att räkna på investeringen.Syfte: Studien har som syfte att öka förståelsen för varför företag väljer att sponsra en elitidrottsförening trots att det är svårt att räkna hem investeringen. Vi har valt att fokusera på fotbollsföreningen IF Elfsborg.Design/metod: I studien används en abduktiv ansats vilket innebär att vi har fått komplettera vår ursprungliga teoridel med mer teori allteftersom vi upptäckte fler delar under vår empiriinsamling. Empirin har samlats in genom en kvalitativ studie där vi har intervjuat personer som är ansvariga för företagets sponsring.

Authors: Daniel Kirby & Émelie Vangen LindgrenTitle: Controlling the WordLevel: Bachelor of JournalismLocation: University of GothenburgLanguage: SwedishNumber of pages: 29The largest arena for public debate in Sweden is the television show Debatt, airing every week on SVT: Sweden?s public service network. Every episode has an audience at around 500.000 viewers. Because the channel is under the rules of the public service agreement, strict rules of diversity are applied.The purpose of this study is to examine the gender representation in Debatt; to investigate how men and women behave in the context of the televised debate and to see if the programme has managed to reflect an equal representation of the voices of men and women.We did this by performing a quantitative content analysis of four different episodes of Debatt, with 4 different hosts ? two women hosts and two men.

Due to poorly functioning local and regional markets, the smallholders in San Francisco, Petén, were dependent on intermediaries that took advantage of the smallholder?s distance to markets. In an attempt to secure income and strengthen their bargaining position, 189 smallholders joined forces through the creation of a social smallholder network, held together by a community based enterprise. This enterprise was initiated in 2011 with the help of government incentive programmes and NGOs that within a few years will leave the enterprise to auto regime. This study treats the sustainability of a community forest based enterprise, Chachaklum, in northern Guatemala. The study identifies factors that enable smallholders to organize themselves in order to obtain business practices that support an improved standard of living.

This paper is a study and comparison between the two Wireless LAN (WLAN) standards HiperLAN/2 and IEEE 802.11a. WLANs are used instead or together with ordinary LANs to increase mobility in for example an office. HiperLAN/2 is an European standard developed by ETSI and the IEEEs standard is American. A WLAN-card consists roughly of a Medium Access Control (MAC), Physichal layer (PHY) and an antenna. The antenna is the same for the different standards.

During the latter part of the 20th century the situation for people with intellectual disabilities in Sweden changed and developed. Clients have the right to participation and self-determination in society and in applied measures under the law of individual rights legislation; LSS. The purpose of this study is to describe and understand how team-leaders and managers in day-centres in a municipality works with participation and self-determination for clients, and what the professionals consider affects the client's possibility to self-determination and participation. The research questions intended to be answered are:? How does the team-leaders and managers work to enable self-determination and participation of the users in the public day-centres?? What does the team-leaders and managers describe and understand as enabling and limiting factors for the client?s possibility to self-determination and participation?The study is qualitative and interviews have been held with eight interviewees, which I contacted through snowball sampling.

Introduction : Structural cardiac malformations affects 0.8-1% of children born worldwide, in Sweden 800-1000 children per year. Most children with congenital heart disease and their families will have frequent and lifelong contact with highly specialized care. Awareness of the parents experience is crucial in order to improve the nursing care. These experiences will be illustrated using a theoretical model of family-based nursing. Aim: The aim of this study was to describe experiences of being a parent to a child with a congenital heart disease.
