Laborationsutrustning till 1FF21I Fartygs- och Verkstadsförlagd utbildning

För att täcka ett behov av laborationsutrustning för enklare felsökningsövningar på dieselmaskinerför första-års-studenter vid Sjöfartshögskolan, Linnéuniversitetet, startades det här projektet. Syftetvar att tre stycken laborationsstationer skulle byggas ovanpå tre stycken kasserade dieselgeneratorersom skolan hade stående. Det skulle på varje station gå att simulera fyra stycken olika fel, och detskulle även finnas underlag för felsökning till varje station. Eftersom utbildningen är engrundutbildning skulle även hänsyn tas till att många studenter helt kan sakna kunskaper ocherfarenheter av förbränningsmotorer.Projektet har arbetat enligt en praktisk metod där problemet formuleras och struktureras samtlösningen planeras och genomförs. Struktureringen gav vid handen att felsimuleringarna bordeomfatta en förbränningsmotors grundläggande system, samt förbränning.

Energiförbrukning för putsade, odränerade träregelväggar i fuktigt respektive torrt tillstånd

In recent years, moisture damages have been noticed in rendered, undrained stud walls. The design is built on the principle one-stage tightening which means that there is no air gap in the construction. The damages have occurred when water has permeated through the rendering in leaking connections and fittings for windows, doors, canopies, balconies, terraces and awnings. Behind the plaster carrier, which consists of either polystyrene or rigid mineral wool, plasterboard has often been used as a wind protection barrier. In many cases the wind protection barrier and the underlying wooden studs have been exposed to mould and in some cases even rot.

Möjligheter och hinder för aggregerad förbrukningsflexibilitet som en produkt på reglerkraftmarknaden

Electricity production from renewable energy resources such as wind energy and photovoltaics is variable. Integration of these intermittent resources into the electricity system leads to new challenges in how to manage imbalance between supply and demand on the grid.One way to meet these challenges is to develop so-called smart grid solutions. One idea, called demand response, is to adjust the amount or timing of energy consumption, e.g. by control of household appliances, to provide flexibility that could be used to balance the grid. In aggregate, when applied to many units across the system, large volumes of energy could be made available when needed and this grid flexibility can be used as a product on the electricity regulation market.Despite the potential benefits, the number of demand response bids is currently low.

"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.

Kalibrering av en transient GT-Power modell av en SI PFI turbo motor

I detta arbete behandlas transient simulering i ett 1D-simuleringsprogram, i dettafall Gamma technologies GT-Power. Vad som behöver ändras i en modell för attden skall kunna simulera en motor under transienta driftsfall med godnoggrannhet har undersökts. När detta är gjort, skall det undersökas hur väl dentransient kalibrerade modellen kan simulera en motor med förändrad rörgeometripå insugs- eller avgassidan, och vad som måste omkalibreras om detta inte ärfallet.Den viktigaste slutsatsen av detta arbete är vikten av att ha en korrekt framtagenkompressormapp i modellen. Den som fanns tillgänglig under arbetet hade baramätdata ned till 70000 rpm. Detta resulterade i en överskattning av massflödet iden lägre regionen i den av GT-Power framställda kompressormappen.

Föräldraskap, kön och jämställdhet i Maria Svelands Bitterfittan

The aim of this Masters´ thesis is to examine parenthood, gender and equality. The analysis is based on the novel Bitterfittan. The primary theoretical points of departure are Judith Butler?s theory about doing gender and Yvonne Hirdman?s theory about the gender system, the hierarchical order and the separation of the sexes. I use Lisbeth Bekkengen?s thesis in which the nuclear family is seen as an institution which is upheld by two structures; that is the social relationships man-woman and parent-child, and also by two discourses; on the one hand a notion that fathers and mothers are principally different and on the other hand the child focus.

The purpose of the thesis was to develop and design calculations andsimulation tools for ABB FACTS?s standard series capacitor platforms.

Representativa testnät försvenska eldistributionsnät

This project was started within the Market-Design programme of Elforsk, with the aim of developing representative test systems of Swedish distribution networks. Using such test systems as a basis for reliability and customer interruption cost calculations makes it feasible to analyse the network tariff regulation of Swedish power  istribution companies. In particular, it enables studies of the incentives for companies to invest in system reliability. Until now, the available test systems are either not representative of Swedish conditions, or too small in scale and limited in function.Within this project we have created two test systems. In order to represent the diversity of actual Swedish distribution networks, we have created one test system for urban environments and another for rural environments.

Vilka faktorer påverkar börsbolagens nedskrivningsbeslut?

By using univariate analysis, tobit and logit regressions, this thesis investigates determinants of asset writedowns. After controlling for variables indicating reductions in asset values, the results show that changes in senior management are significant in explaining the writedown decision and magnitude, which is in line with previous research. The explanatory power of changes in senior management has not increased with the transition to IFRS in 2005. No evidence is found supporting the hypothesis that the explanatory power of management incentives is higher for more discretionary types of asset writedowns..

Diktaturmänniskans fall : Bilden av Spanien i Per Wahlöös texter 1951-1962

Per Wahlöö is one of Sweden´s most famous crime writers. Together with Maj Sjöwall he revolutionized the swedish crime novel in the mid-sixties with the Martin Beck-series. Before that he was working as a reporter in the fifties and started writing novels about the oppression of man, power and totalitarian mentality in the end of the decade. Those novels (1959-1968) are called ?The dictatorship?-series.

Fortsatt gran eller självföryngrad björk efter stormfällning? : en ekonomisk analys

The southern part of Sweden, Skåne, is frequently exposed to storms causing great damage to Norway spruce (Picea abies L. Karst.) stands. A storm during the winter 1999/2000 raised the attention of the problem. A lot of forest owners got large areas of spruce stands wind thrown during this storm. Can naturally regenerated birch (Betula sp.) be an alternative on these wind-exposed sites? This was the main question I was facing when discussilig the problems with Esben Möller Madsen, Söderåsens forest district. The aim of this master thesis was to present an economic analysis of Norway spruce versus birch.

Simulator för el- och värmeproduktion : påverkan på ekonomi och miljö

In this project a simulator has been developed (in C++) with the purpose of illustrating how changes in environmental regulations, tax levels and other policy measures affect the composition of an energy system. The aim of the project was to investigate how energy companies? investment strategies are affected when changes in economic and environmental conditions occur. A standard scenario has been created based on current Swedish conditions, but the user can create new scenarios and set parameters freely. The user is tasked with building power plants to supply the city/region with district heating and electricity during a pre-set number of years. When the simulation is finished the result is graded in the following categories: economy, environment and quality. To evaluate the simulator three scenarios were created (?early 20th century?, ?reduced environmental control? and ?future?) in addition to the standard scenario and these were compared with each other by examining how a select group of power plants perform under the given conditions.

Styrketräning för truppgymnaster : mer än bara kroppsvikt som belastning?

Syfte och frågeställning: Syftet med denna studie är att undersöka de eventuella fördelar styrketräning med yttre belastning kan ge kvinnliga truppgymnaster på juniornivå. Frågeställningar: Vilken effekt på explosivitet i nedre extremitet har sex veckors powerträning med yttre belastning på truppgymnaster? Skiljer resultaten sig från de som uppnås vid traditionell gymnastisk styrketräning?Metod: Två lag som representerar Sverige-eliten på damsidan i juniorklassen delades in i test- (n=7) och kontrollgrupp (n=8). Testgruppen genomförde under sex veckor ett specialdesignat träningsprogram riktat mot power medan kontrollgruppen genomförde traditionell gymnastisk styrketräning. För- och eftertester genomfördes för att utvärdera effekterna av programmen.

Alternativa stråbränslen i växtföljden :

The purpose of this report is to find out which crops, that are good for strawfuel, and can be grown i the area around the city of Lund. The background of this report it that Lunds energy is planning to bild a biofuelheated thermal power station in Örtofta outside of Lund. I have in the report limited me to the crops hemp, whole crop (triticale), reed canary grass, elephant grass and jerusalem artichoke. I have through a documentary research checked the crops, cultivabillity in the south of Sweden, and how they should fit, in the Scanian crop sequence. Hemp is an annual crop which probably could manage in the Scanian crop sequence. Whole crop often triticale because of it´s high yield and low rate of shed seed. Could also fit into the crop sequence of crop in Scanian. Triticale is annual, and could be grown at the same kind of fields as used to wheat, whith is why it would be possible to grow it in Scania. Reed canary grass is a reedlike grass that is easy grown at most soils.
