Dynamisk simulering av avfallskraftvärmeverk
On a request from the water sewage plant Gryaab in Gothenburg a power quality survey was performed. The voltages and currents have continuously been sampled in the incoming 10 kV substation HSP01 from April-August 2008. Power quality measurements were also performed in Gryaabs other 10 kV substation HSP04 fed from HSP01 and at the terminals of the induction motor IN_PU4040 of 1.3 MW which controls one of the four large inflow pumps to the plant. The reason for the latter measurement was due to registered negative transients each time the motor was connected to the grid. The cause of the transients could be explained by the coupling in the substation, the ageing of the motor which could result in damage of the bearings or resonance in the motor circuit which amplifies high frequency harmonics.
Motivation at Work?
The purpose of this diagnostic master thesis is to examine the motivation of the individuals working in a specific section at Sony Ericsson BGNMVNL. In order to do this, we will distinguish motivational and de-motivational factors that influence the individuals? in their work. Further, we also have the aim of giving recommendations on how to act on these outcomes in order to improve the motivation in BGNMVNL. Our thesis is a diagnostic study in which data is collected by qualitative face-to-face interviews and observations with selected individuals at Sony Ericsson.
Mer ekologisk mat : i Jämtlands läns landsting
Authorities, municipalities and county councils have great opportunities to pave the way to a sustainable society. In the public sector, the tax revenue is used and therefore it is important that both employees and societal stakeholders feel that they participate in the sector?s decisions and fields of application. Municipalities and county councils are primarily service organisations. The employees? commitment is necessary to be able to reach set goals, to develop procedures and policies that support the overall political goals, in other words, to be successful in the environmental work.
Övervikt hos husdjur : djursjukvårdarens roll
The obesity problem in the world is growing bigger and today even our companion animals are becoming heavier. In this paper the importance of a balanced diet for the companion animal is emphasised. There are many disadvantages for the animal and for the owner if the animal becomes obese and it is important to stress the facts on what the consequences might be. There are several medical conditions connected to obesity and a short summary of these will be discussed. It is often easier to prevent obesity rather than loosing the overweight and some ideas of how to do this is looked in to.
In many veterinary clinics today, the veterinary nurse is the first and sometimes the only person to see the animal.
Carlstad Comic Con : En fallstudie
This is a case study of Carlstad Comic Con 2011 and 2012.The purpose is to study the event in relation to a project management and a local culture policy perspective. This in order to analyze the organization of a popular culture event and see how such a local event may benefit Karlstad as a city. Besides studying the organization of Carlstad Comic Con and its outcomes I am sketching a short cultural history of popular culture media and its context within recent year?s globalization.The study shows that the events have had a great beneficial impact on the local industry; lacking any negative sides, and have put Karlstad in an international context which goes directly in line with the standard guidelines for project management of region culture policy. Concerning how to organize the event the organizers have not followed a strict project structure.
Energianalys av Vikan Kross och Asfalt
On a request from the water sewage plant Gryaab in Gothenburg a power quality survey was performed. The voltages and currents have continuously been sampled in the incoming 10 kV substation HSP01 from April-August 2008. Power quality measurements were also performed in Gryaabs other 10 kV substation HSP04 fed from HSP01 and at the terminals of the induction motor IN_PU4040 of 1.3 MW which controls one of the four large inflow pumps to the plant. The reason for the latter measurement was due to registered negative transients each time the motor was connected to the grid. The cause of the transients could be explained by the coupling in the substation, the ageing of the motor which could result in damage of the bearings or resonance in the motor circuit which amplifies high frequency harmonics.

Lärares erfarenheter av arbete med elever som far illa
The purpose of this study was to investigate the association between physical activity and perceived stress, energy and musculoskeletal disorders among office-workers and warehouse-workers and also to see if there were any differences depending on work-place and gender. The method that was used to collect data was three different validated questionnaires that measured stress and energy (the Stress-Energy questionnaire), musculoskeletal disorders (intensity and localization of pain, a Pain Drawing questionnaire with a VAS-scale) and physical activity (IPAQ ? the short version). Eighty-eight workers participated in the study. Forty-seven of them were office-workers and forty-one were warehouse-workers.
"Det" - Profession och giltighetsanspråk i läraryrket
During my one year master in pedagogic science, I was frequently given the impression that depicts the pedagogue?s profession as a rather transcendent talent or, more precisely, a matter of having ?it? or not. It seemed to me, as if the communicative part of the teacher?s specialised skill was more or less undefined in the description of what makes the pedagogue a professional pedagogue. On those premisses, I was led to the aim of this study, which is pursuing the very essence of the profession by discussing how five teachers validate their daily work from a habermasian perspective on communication, society and pedagogy.
Barn kommunicerar om film
The aim of this master?s thesis is to obtain greater understanding of how children relate to the film medium and their experiences. This is obtained by listening to the children and observing their verbal and nonverbal communication in two focus group interviews. Children?s access to and selection of film are due to adult?s restrictions.
UV-tork - analys av drift :
The company Somas, Säffle, has assigned Fredrik Kjellin the project of finding out how ?KVTF DN250?, one of their own valves, reacts on cutting forces under production. They wish to know if and then how much it?s possible to minimize the wall thickness of the valve with neither plastic nor to big elastic deformations caused by processing.The most critical processes have been identified as rough lathing. The study has shown that the marginal for a wall thickness of two millimeters, to fall short of the yield stress in the most critical process, is good.
Design and Analysis of an All-optical Free-space Communication Link
Free Space Optics (FSO) has received a great deal of attention lately both in the military and civilian information society due to its potentially high capacity, rapid deployment, portability and high security from deception and jamming. The main issue is that severe weather can have a detrimental impact on the performance, which may result in an inadequate availability. This report contains a feasibility study for an all-optical free-space link intended for short-range communication (200-500 m). Laboratory tests have been performed to evaluate the link design. Field tests were made to investigate availability and error performance under the influence of different weather conditions.
En kritisk granskning av svenska statens ställningstagande till barns deltagande i domstolsförfaranden
The aim of this study was to describe and scrutinise the position of the Swedish government on whether children should participate directly or through a representative in judicial proceedings.The main questions for this study were to find out (1) what position the Swedish government has on the subject, (2) how the position is justified, and (3) what view on children the position reflects.A qualitative design was used in the study and in order to describe the position a descriptive method was used. In the second part of the study a critical approach was used to examine and analyse the position.The main conclusions were that the position is ambiguous but that it mainly reflects, with a few exceptions, that it is better for children to be represented than to participate directly in judicial proceedings. The arguments that are given as basis for the position are short and lack both the objective and subjective grounds needed to decide the best interest of the child. The analysis of the position showed that it mainly reflects a view on children as objects and when the statement reflects a view on children as subjects, it relates to age and maturity in the child..
