Analys av PWM-mönster i Matlab

One of ABB Power Systems´s business areas is HVDC (High Voltage Direct Current) technology. HVDC is used for transmissions for both short and long distances. One of Power Systems?s products is called HVDC Light. HVDC Light is a relatively new technology for power transmission, but have before only been used for motor drives applications.

Import av avfall för energiutvinning ? en systemanalys av avfallshanteringens klimatpåverkan

This study has examined if importation of waste for energy recovery can reduce the climate impacts of Waste Management Systems. Using Systems Analysis this study will try to examine the complex waste systems in a systematical and strictly logical way to see how these systems interact and affect each other. Specifically examining the climate impact of waste management systems in England. The traditional way of handling waste in England is through Landfills. Land filling leads to emissions of the greenhouse gas Methane. The EU has put in place a landfill directive that is supposed to lead the member states away from land filling as a method of waste management. Today in Sweden there is a competition for the waste available for incineration. The worsening economical situation together with less product packaging and an increase in source separation leads to a lack of waste available for incineration.

"Det som är hemskt känns väldigt hemskt i den åldern...". En kvalitativ studie av skydds- och riskfaktorer för depression hos unga vuxna samt familjeförhållandenas betydelse för behandling och tillfriskningsprocesser

The worsening of psychical health issues among young people has widely been discussed over the last few years. Research shows for example that 9% of girls at the age of 16-24 reported anxiety problems in 1989 while 16 years later, in 2005, the same number was 30%. The purpose of this essay was to study and analyze psychiatrists', psychologists' and counselors' view on the resilience and risk factors for youth depression (age 16-24). Beside this, our aim was to study their view on the influence of family environment on treatment and recovery. Data were collected with qualitative interviews with eight informants within the psychiatric care.

Samtidigt fokuserar tja?nstefo?retagen alltmer pa? fo?retagets personalresurser och att kunna erbjuda na?got uto?ver ka?rntja?nsten fo?r att differentiera fo?retagets position pa? marknaden.

VSM och 16 förluster

With background in the rapidly growing need to find solutions for sustainable energy production and the increasing interest for wind power, this report was written. With take-off point from the wind power plant Big Glenn, which has been built in the harbour of Gothenburg, a model of the adjacent power grid has been created in Simulink/SimPowerSystems. Parameters for the power grid and its components has been provided by Göteborg Energi Nät, that has also been the supplier of measurement data of produced power, the power need from loads in the vicinity, voltage levels, current values and also the variation of power factor at the wind power plant.The SimPowerSystems model has been used to perform simulations of power flow in the grid. These simulated values have then been compared to the measured values to verify the functionality of the model. Further, the model has been used to perform simulations of a grid fault, which causes a voltage drop.

Dimensionering av hjälptransformator

The aims of the following project has beento make a proposition how to create aspecific kind of transformer. Thefollowing report evaluates the differentimportant variables and contains asuggestion for a possible design. Intheory it's an ordinary transformer that'ssuppose to transform electrical effect toa high voltage line. The design of thetransformer is using an already existingcurrent transformer design and is adjustedto work for it's specific purpose. Theproject also contains the developing of atransformer simulation model that will beused to evaluate and optimize thedimensions of the resulting transformer..

Vasaskolan i Gävle 1865-1899 : en studie i social tillhörighet hos läroverkets elever

The conception of exhaustion was first used in the end of 1960 and was then used in a psychological context directed towards the working life. Eventually was the conception devided into two main categories: mental and somatic symtoms. Today research of exhaustion is mainly aiming towards recovering and returning to working life.This work sets out to analyse the importance and effects of social networks such as family, friends and professional relations in helping people who suffer from exhaustion to recover. The study is based on interviews with eith people who have suffered from exhaustion but today are recovered. To my aid I have used tree different questions: What part have the social network of family and friends ment to the recovery? What part has the professional relationships with doctors, therapists and curators ment to the recovery? How have you changed your life in order to maintain balance?The interviews pointed out the importance of the social relationships as support, feedback and understanding that the process takes time.

Det publika samtalet som curatorisk praktik

The focus of this study is on the nature of social support from the rape survivor's perspective. Research has shown that social support is essential to the survivor's ability to recover from rape and that it acts as a powerful tool for the survivor to effectively deal with the PTSD symptoms that follow rape. The research also shows that survivors often receive or interpret reactions after a rape as negative. Hence, these reactions can be detrimental tothe healing process.Qualitative interviews with six women on their experience of social support after rape form the base of this study and Anthony Giddens terms ontological security, fateful moments and bodily self-management are a part of the analytical apparatus. Rape is commonly analyzed from a feminist perspective.

Comparison between anesthesia with sufentanil-midazolam and sevoflurane in medetomidine premedicated rabbits undergoing ovariohysterectomy

Rabbits carry a high risk of anesthesia related death. This study was part of a project to develop a form of total intravenous anesthesia (TIVA) with minimal effects on cardiac, respiratory and metabolic parameters. In the study, TIVA with sufentanil and midazolam (group TIVA, n=9) was compared with inhalation anesthesia with sevoflurane (group SEVO, n=9) in female rabbits undergoing surgery (ovariehysterectomi). All rabbits were pre-medicated with medetomidin and carprofen before anesthesia induction. Anesthesia was induced with TIVA (2.3 ?g/ ml sufentanil, 0.45 mg/ ml midazolam) at a rate of 4 ml/ kg/ h and the mean induction dose was 0.4 ?g/ kg of sufentanil and 0.1mg/ kg of midazolam.
