The purpose of this thesis has been to develop a tool for modelling and simulating the nuclear plant Ringhals 3. The model should be used to improve the knowledge on the dynamics of the plant. Ringhals 3 is being upgraded to produce more power and a tool for analyzing the new operating conditions is needed.The work in this thesis has consisted of improving and developing an existing model of Ringhals 3 made with the modelling tool Dymola. The model has been validated by comparing the results of a simulated house load transient with data from the actual plant. Validation shows good agreement with data from the real plant.
"Jag blir den du säger att jag är" : Intagnas upplevelser kring bemötande och maktutövning på kriminalvårdsanstalt.
Prisons are for many an unknown world, and few know about the prison culture which includes unwritten rules, power structures, interactions and relationships between inmates and correctional employees.While many think that Swedish prisons are too comfortable,inmates are facing extreme stress due to surveillance and detention, by depriving inmates their possibility to shape their own lives. When the inmates is deprived of control over their own life?s the penal system have great power to shape and to influence the inmates.The purpose of this paper is to investigate prisoners' experiences of treatment and exercise of power in prisons. Starting point is to examine what are the kinds of relationships between prison officers and inmates from a power perspective, if there is any difference between the closed and open prisons and how the inmates affected by the structures that exist.Based on my overall purpose, and with my informant´s stories which revealed a number of similar points, four main headings were developed; Mass media and society´s view, and unknown world, interaction between inmates and prison officers and consequences.Prison officers with the role as a contact persons as well and other staff which work close to the inmates play a significant role by supporting through motivational interviewing and can help the inmates to gain insight about their life situation and actions. My informant?s underlined that a good contact person can either help or discourage.Inmates who contributed with their experiences express that there is a big difference between open-and closed prisons.

Rundstyrning i lokalnät : En förstudie i tekniska och ekonomiska konsekvenser för Värnamo Elnät AB
Värnamo Elnät owns and operates a ripple control system which is used to control loadsespecially when the grid is heavily loaded and for control of street lighting. This report aims atclarifying technical and economic aspects of the ripple control system?s future. The system wasinstalled from 1975 and onwards and its use was greater in those days when the controllableloads where greater then today, the current controllable load level is about 3 MW. The reporthighlights three different aspects of the ripple control system?s future ? retain the currentsystem, reinvest in a newer system or discontinue the system.In the report the author also discusses relevant connections to Smart Grids and future meteringsystems and tariffs.
Erfarenhetsåterföring inom anläggningsbranschen: Vad sker idag och vad kan förbättras?
Denna rapport beskriver arbetet med utvecklingen av en ny modell för kaplanturbiner. Utvecklingen bygger på två kopplade differentialekvationer som under arbetets gång anpassats och implementerats i turbinmodellen.Modellen beskriver hur vattenflöde och turbinmoment påverkas av avvikelsen från den optimala kombineringskurvan för vinklarna på turbinens ledskena och löphjul, och är anpassad för ett referensaggregat med tillgängliga provdata. Även övriga enheter i vattenkraftaggregatet modelleras och sätts samman med frekvensregulator och elnät för att simulera aggregatets reglerstabilitet i önätsdrift.Verifieringen av turbinmodellen sker genom försök att återskapa de befintliga verkningsgradskurvorna med hjälp av modellen. Resultatet visar en god följning av de verkliga kurvformerna, dock med något lägre maximal verkningsgrad.Verifieringen av önätmodellen sker genom att prova stabiliteten i nätfrekvens och turbineffekt vid stegpålastningar. Resultatet ger en stabilare reglerstabilitet än i verkligheten, men uppfyller ändå förväntningarna på en fungerande modell.This report describes the development of a new kaplan turbine model.
ADHD som meningsskapande diskurs : om ADHD i socialt arbete i kriminalvården
The aim of this study is to discuss the diagnosis ADHD as a meaning-making discourse that is something more than just a diagnosis with a set of symptoms. I aim to discuss that the diagnosis is productive and can be seen as a means to control and to comfort individuals. The research was based on a method consisting of an idea analysis and a discourse analysis. I am using both a discourse analysis and a critical ideology analysis as perspectives. These perspectives are also based on a general theory of late modernity.
Handlingsutrymme : En kvalitativ studie - ur ett socialsekreterarperspektiv, gällande insatser för barn till föräldrar med psykisk sjukdom
How does a social welfare officer know when a parent with mental illness or behavioral symptoms is harmful to the children? As a social you are confronted with different ethical dilemmas on a daily basis. The social welfare officers have to follow their own authorities, laws, guidelines and regulations while at the same time do everything to satisfy their clients? needs. This inconsistency can sometimes be difficult to handle.
Ovidkommande vatten i spillvattensystemet - problematik och åtgärder
The purpose of this essay was to examine whether small businesses can avoid ac-counting crimes with a well-conducted internal control system. The questions we asked ourselves was, whether and if so, companies can prevent this from happening by using a internal control.In this essay we used a qualitative approach. Essential information was given to us from four different interviewees. We also worked from an inductive approach which means that we interviewed people without any earlier research to build on. The method also had a hermeneutical approach, which means that we made different interpretations based on the reference framework and the empirics.After the study had been carried out, we concluded that all evidence from this essay suggested that even small businesses need an internal control to protect their business.

Inställning av automatikermed spänningsreglerande verkani det sydsvenska 400-130 kV nätet
The voltage level in the power grid varies due to variations in load and production. Normally these variations are manageable, but they may be excessively large during a disturbance. If the voltage is too high it may damage the equipment in the grid and too low voltages may cause problems like voltage instability. The magnitude of the voltage variation depends on the short circuit power capacity of the point of interest.This problem may become lore prominent due to automatic voltage regulation that acts on shunt reactors and shunt capacitors. When the shunt reactor is connected or disconnected to the grid it may cause such large changes in the voltage that the shunt reactor starts hunting.
En diskursreglerad v?rld: Makt, kunskap och agens i Mark Lawrence? The Book That Wouldn?t Burn
Historically the library has owned more than silent, book-filled halls; it has been a center for learning and ideas, a source of both freedom and oppression, in other words, a medium for knowledge, truth, and power. Cultures have been divided into powerful and powerless through access to the library's content; those who have - and those who do not have - access to information determine which voices are heard and which are ignored, thus determining the outcome of the future.
This thesis investigates how The Book That Wouldn't Burn by Mark Lawrence portrays the relationship between knowledge and power using Michel Foucault's discourse theory. More specifically, how this relationship is manifested through the structures and norms of society, and how the library as a place and institution serves as the means by which this relationship plays out. An established classic like Fahrenheit 451 by Ray Bradbury is placed as a contrasting reference point to help deepen its thematic message of information control and cencurship. Furthermore, the agency of one of the main characters is also examined in the light of Anthony Giddens' stratification model, as an actor with the potential to move beyond the confines of the power structure.
The analysis demonstrate how knowledge, truth, and power remain continuously thematically relevant within literature, and how the reality of our time may be better understood through literary contributions.
