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.

People spend much of their timeat work and health is affected by how we experience our everyday work situation. Health in the workplace is important for public health and seems to improve the occupational health of theemployees. The pace of work and requirements have hasincreased at work and it's not equal accepted to have an obstacle that makesyour work capacity decreases. Despite this, there are health factors that enable us meet therequirements and can maintaingood health in the workplace. Theaim of the studywas to see if there has beena change in healthcare workers work-related health over time.

The Swedish armed forces has for many years educated squad leaders by letting them start their training two and a half months before the soldiers start their training. 2007, this system was used for the last time. I went trough this system myself in 2005 and had a positive experience and when I did my internship I experienced a slight difference in the attitude of the squad leader. I talked with my colleges at the company and they had felt the same. This essay will try to analyse if the squad leaders has lost any of there ability and if so, what could be the cause? To analyze the ability of the squad leader in this essay it will first analyze their ability through the Direct leadership theory, which is the theory that is presently used in the Swedish armed forces.

When cylinders for motor saws are manufactured there are high demands on the cylinders strength and wearing qualities. Aluminum is a material with low density and is used by Husqvarna AB for their motor saw cylinders. The aluminum is strengthening with nickel that is attached to the cylinders through electrolysis. When aluminum is in contact with oxygen a film of oxide is formed. To eliminate the oxide and to prevent formation of new oxide zinc is used.

This paper presents a study of the Swedish public service television broadcaster - Sveriges Televisions (SVT) transfer pricing model. The aim of the thesis is to examine the motives for using transfer pricing from a theoretical perspective and if SVT?s transfer pricing model fulfils these motives. We will also examine any potential managerial problems the existing transfer-pricing model might cause and discuss how these could be solved. We have in our study found that the main motive for using transfer pricing within SVT is to allocate internal resources as efficiently as possible.

The need for a more efficient electrical grid has made the smart grid concept popular in recent years. The aims of this study are to identify the conditions in Sweden for implementing a smart grid and to analyse the opinions of stakeholders. One finding is that the large capacity of Sweden?s existing electrical grid decreases the immediate need for smart grid solutions. However, the rapid increase in wind power might push the development of a smart grid in the coming years.

Background: Practical blood flow restriction (pBFR) combined with resistance training has been proven to facilitate muscle strength despite training at low intensity. However, research investigating the effects of long-term pBFR-training and its periodization with strength training (ST) at a higher intensity is lacking, as well as the effects of occlusion training on blood lactate levels (BLL) over time.Purpose: To compare the effects of 2 weeks of pBFR training followed by 2 weeks of ST (BFR-ST) with 2 weeks of ST followed by 2 weeks of pBFR training (ST-BFR) on anaerobic performace and BLL.Method: 5 adults (age 23 ± 2 years) with a minimum of 1 year of ST experience were recruited and randomized into BFR-ST (n=2) or ST-BFR (n=3). Anaerobic performance was measured using a 30-s Wingate-test and BLL samples were collected <1 and 5 minutes post-Wingate. Data and samples were collected before the intervention and after the 2 protocols.Results: No differences were seen between groups in anaerobic output or BLL after 4 weeks of training (p>0,1 for all values). A decrease in time to peak power (tPP) were seen in both groups with an advantage for BFR-ST (-37 ± 8 %) over ST-BFR (-27 ± 22 %).

With examples from a single classroom situation, several educational moments show what goes on between the teacher and the student. The teacher?s responsibility in the learning process is, with a gesture frozen in the air of the moment, to lead and follow the student in her tentative efforts at seeking knowledge. Initially, it is an attempt to shed light upon the "not yet seen" with a certainty that the student herself possesses the capacity and the aptitude to reach greater insight and clarity in her understanding. The Validation/Feil Method presented in this instructional situation illustrates how best to communicate with elderly people suffering from Alzheimer?s dementia.

Nature´s healing capacity is well known and is today an important asset in the protection against stress. Noise problems in cities and it´s green spaces are increasing which in turn provokes stress and in the long term can lead to cardiovascular diseases. To promote people?s health it is important that natural environments have good soundscapes, research show that visiting natural surroundings and listening to sounds of nature promote rehabilitation and relief stress. The purpose of this essay is to determine the value of rehabilitation in forests in Carlshem and Röbäck.

To succeed, a word that can be interpreted in many different ways. In this thesis the authorshave highlighted the word succeed with success. There has been a case study of twocompanies, which managed to penetrate a competitive market which is still under expansion.These brands are popular and maintain a high standard. Boomerang and Vagabond are twoSwedish companies which not only managed to penetrate the Swedish market, but also aninternational market. These are two Swedish companies which started from scratch as anyother company.

The energy in laundry rooms, in form heated air, can be utilized with a heat exchanger. A concept and an early prototype of the heat exchanger have already been developed to show that the theory works. This report describes the continued development and construction of the product.A field study was made in order to investigate the environmental usage and establish the product design. The most common washing machine was used as a calculation model, and calculations were also made to estimate the amount of energy in the air. A previous analysis of the existing prototype is also presented in this report, to show the products potential capacity.

A Swedish electronics company wants to make the cooling of one of their electronic components more efficient. They propose that a retrofit liquid cooler is the way to achieve this goal. The current air cooling has high energy cost due to the high amount of power needed to power fans and heat exchangers. Using high volumes of air for cooling also leads to noise pollution. The conversion from air to liquid cooling would possibly make the operation of the electronics more cost efficient and less noisy.The purpose of this project is to theoretically evaluate different concepts of drawing the heat generated by the electronic component in to a fluid, using numerical calculations in Matlab and FEM simulations in ANSYS.

Vocational rehabilitation is an ongoing issue that directly or indirectly affects everyone at a workplace. In recent years, laws and rules have changed. The 1st July 2008 changes were made in the General Insurance Act (SFS 1962:381). These changes have meant that there is now a so-called rehabilitation chain.  The rehabilitation chain contains time frames for when sick people will have their ability to work tested against their normal work or to other jobs. If a person is considered having enough capacity to be able to work he or she will lose their entitlement to sick pay.The aim of our study is to investigate managers? perceptions of the new rehabilitation chain, with a focus on vocational rehabilitation of long-term sick to get them back to work.The method used was qualitative and data collection was done through nine semi-structured interviews.

Data consists of qualitative interviews with students and parents who experienced the method during the last years. Violineurhythmics can be seen like a genre of the method of the rhythmic.

This report summarizes the development of a calculation program estimating the profitability of converting a peak-load oil-fired boiler to pellets. To convert an oil-fired boiler to pellets a new fuel handling system must be designed. Changes also have to be made to some other components. Since there are many different techniques for transportation, storage and treatment of the fuel only the most interesting techniques from Swecos experience and interest were included in the study.The capacity of the different parts in the system was dimensioned based on the power of the boiler after conversion. To estimate prices, installed power and dimensions manufacturers and distributers were contacted.
