Numerical simulations play a vital role in both static and dynamic stability assessment of electric power systems and the foreseeing of voltage collapse. Simulations performed by Svenska Kraftnät(SvK) are mainly done in the specialized voltage collapse predicting software tool, SPICA and the more all?purpose software tool, ARISTO.The grid operators at SvK use SPICA to predict the maximum transfer limit at specified sections (in this report the section in concerns is the southern part of Sweden i.e. interface1 4). SPICA is mainly used as an online application by using actual states from the grid, these states update every quarter of an hour.This thesis is a continuation of the master thesis SPICA ? ARISTO JÄMFÖRELSE by Jakob Katzman and Johan Fält.

The study of medicinal plants is a popular subject that, at least in the archaeological sciences, has met a lot of criticism due to the lack of physical data. It is problematic to distinguish the medicinal plants from local flora since many herbs that were used often could be found in the nearby vegetation.  The purpose of this essay is to archaebotanically analyze samples from the medieval town Nya Lödöse and compare the data with a previous analysis from the site and a literature study. The herbs meadowsweet (Filipendula ulmaria), lady?s mantle (Alchemilla sp.), sweet gale (Myrica gale), hop (Humulus lupulus), common tormentil (Potentilla erecta), St. John?s wort (Hypericum perforatum), henbane (Hyoscyamus niger), catnip (Nepeta cataria) and motherwort (Leonurus cardiaca) have been selected for closer analysis since they occur with frequency in the historical medicinal texts and in previous analysis made on the site.

The aim of this study was to understand how social workers perceive and understand violence and threats of violence from clients, and how it effect their working environment. It seems that the respondents understand the violence and threats of violence from clients as a result of the clients background problems, vulnerability, dependency and from ?the reason" that the client is currently in the contact with the organization. How respondents interpret the client´s behaviour based on the above-mentioned factors, seem to determine how the respondents perceive and define the violence and threats of violence by clients directed against them. Interestingly enough, although all respondents in the study experienced violence and threats of violence from clients, none of them perceived themselves as exposed at work. The answer to this is consensual.

The aim of this essay is to study the decision making process and implementation of the principle of political participation and influence for Roma minority in Sweden. The results regarding the decision making process is structured through a discourse influenced policy analyses. Problem picture and recommended measures in the political documents representing the decision making process are analysed through theories of minority rights and equality. The implementation is seen through, by the author given minority discourse and the work in the roma council and analysed by the same theories already mentioned.The results show that regarding the decision process the aim of art.15 in the framework convention is based on the idea of equality while the Swedish documents relates more to an idea of the right to speak for the group. Regarding recommended measures, the framework convention gives several recommendations on specific measures for political participation while the Swedish documents focuses on the general politics of the state.

Vattenfall AB is a large producer of electric energy where approximately half of the energy comes from hydropower. Vattenfall Hydropower has got almost a 100-year old history and the company has developed a lot since 1909. After that the number of power plants increased and the competition got more intense, there were higher demands on the reliability. One way to secure the reliability with a good satisfaction at the power plants is to implement a maintenance method named Reliability-Centred Maintenance. RCM is a result of the introduction of the complex aeroplane Boeing 747 in the 1960?s.

This thesis aims to investigate possible positions of identification for people with dis/abilities. With a theoretical basis in crip-theory it discusses the notions of power and deviance and its? importance for the formation and reproduction of ideas around the concepts of dis/ability, ableism, deviancy and normality..

The aim of this thesis is to develop a new business model for district heating and cooling firms which can contribute to a stabilization of the Swedish national energy system. The business model is developed for a district heating and cooling firm and is exemplified with Fortum Heat. The theoretical investigation around the topic creates a rigid base for following qualitative empirical studies. Osterwalder?s canvas for business model generation is used together with a Casual Loop Diagram to identify a number of business opportunities which stabilizes the national energy system.

This thesis is about how the front-staff in two service companies experience empowerment. Competition for business in today's society is becoming increasingly fierce, which means that they must find a way to differentiate themselves from competitors. Service has become a way to compete. Front-staff competence and ability to offer a good service is a crucial factor when the company's success is being measured.Empowerment in business is used as a tool to create motivation and satisfaction of individuals at work. Companies using empowerment can create the freedom and opportunities for employees to act at their own intelligence and discretion.

Dichotomy in change ? a study of how the relationship in terms of power between politicians and civil servants in local government is affected by the transition to a system without branch committees.

Title: Merkel with NSA on the telephoneThe aim of this essay is to study how Angela Merkel is being portrayed in context of NSAs surveillance in the Swedish newspapers Dagens Nyheter and Aftonbladet. The time period for the study is from the 24th of October to the 7th of November in the autumn of 2013. To concretize the aim three questions was formulated, how Angela Merkel was being portrayed in the material, how NSAs surveillance of Angela Merkel was being portrayed in the material and how different statements for various individuals in the material could affect the truth about the surveillance. The method chosen to study these questions was a discourse analysis, which also would contain parts of a linguistic analysis. The theories to support the method were Laclau & Mouffes discourse theory and Michel Foucault?s genealogical discourse analysis.

The aim and goal of this work has been to design and implement a voltage reference network for a 12-bit PSAADC, Parallell Successive Analog to Digital Converter. A chip containing the design has been sent away for fabrication. Because of the long processing time, no measurement data are presented. The main specifications for the voltage reference generator is to generate stable reference voltages with low noise and a good PSRR. Efforts has also been made to minimize the power consumption..

The purpose of this study was to examine how the personnel of the Employment Office in Malmoe interpret the emotional situation and health of unemployed individuals. We also wanted to examine if and how the personnel work with these aspects. In relation to this we found it very interesting how the personnel dealt with the responsibilities of power, hierarchy and how subordination afflicts the unemployed. Our main questions were: Are the previous studies results confirmed by the response the personnel of the Employment Office give about the difficult situation among unemployed individuals? Which factors do the personnel at the Employment Office consider the main causes of negative emotional situations among the unemployed? How do the personnel deal with the emotions of the unemployed? How does the important responsibilities of power affect the relationship between the personnel and the unemployed? Which effects/impacts from current political changes are the personnel able to see on the situation of the unemployed? We interviewed eight people working at the Employment Office in Malmoe.

The company Olofsfors AB manufactures drive belts for forest machinery, known as ECO-Tracks, and abrasion-resistant steel and cutting edges for graders, excavators and tractors, known as Bruxite and SharqEdges. Manufacturing these products requires the steel to be heated and molded, then submerged in water and hardened. The water used in the hardening of steel is pumped to the process from pits below the floor and then pumped back to the pit after it?s been used. Since the temperature of this water rises after being used to harden the steel the temperature of the pumping pit needs to be adjusted to maintain its setpoint of 21°C.

By limiting our horse?s freedom of movement, we restrict their opportunity to forage, which is one of their most important needs. If their need of forage is not fulfilled it can lead to frustration, which might manifest itself in abnormal behaviour, like the oral stereotypies for example crib-biting. It is a held belief that the horse swallows air while crib-biting, which they don?t, and that swallowed air causes colic, and the belief that other horses can copy the behaviour, leads to the use of many methods to prevent the behaviour.

The aim of this master?s thesis is to explore concert institutions? informative texts prior to upcoming concerts ? texts in promotional materials and descriptive texts in programme papers. The thesis is carried out from a critical discourse analytical perspective. The discourse analysis is focusing on finding the texts? messages and it asks the question: To whom are these texts addressed? Theoretical support is mainly taken from Foucault?s theory about the relation between power and knowledge.
