Mänskliga och skriftliga informationskällor - en studie om vari värdet ligger i att få information på mänsklig respektive skriftlig väg

Abstract: The aim of this study is to investigate the attitudes towards the labour movement?s strategies, goals and organisational issues in Swedish Miners? Union?s (Gruvindustriarbetareförbundet, hereafter Gruv) paper, Gruvarbetaren 1917-1925.The theoretical starting point is Engels? view on the class state. This perspective turns the question of socialism and the way to get there into an issue of working class power over the state. Another theoretical perspective is the partition of the labour movement into a trade-unionistic branch, seeing unions as financial organisations of interest, and a pro-state one, considering unions as political organisations.During the period investigated Gruvarbetaren was quite radical and advocated a firm class struggle strategy towards employers. Since these were considered unreliable, class struggle was seen as the only way to better the conditions for the working class.

Risker i flera dimensioner : Om kopplingen mellan designmönstret MVC och projektrisker

The purpose of this project was to further develop and complete a quadcopter that had been built in an earlier course at KTH, so that it could be used for demonstration and education at the school. The quadcopter was at the beginning of the project completed when it came to hardware, and there was some software functionality implemented but no system for automatic stabilization. The main goal of the project was to implement such a system, and to combine it with the previous functionality to make the quadcopter operable and able to fly. To create a functioning and stable ground multiple basic software features has been implemented, and on top of that additional software to improve the safety, stability and functionality. The most important part is the control system that is responsible for converting sensor and control signals to suitable motor values.

En övervikt av kvinnor : En kvantitativ studie av bilder och skribenter på Aftonbladets viktsajt ur ett genusperspektiv

We have investigated the visual representation of men and women in Aftonbladet?s weight site. We have made a calculation of how many of the women and the men who were portrayed smiling/ not smiling, active/passive, looking into the camera/looking away from the camera and from which camera angle the picture is taken. We also kept statistic on the gender representation of the authors of the articles.Our investigation shows that Aftonbladet?s weight site has a distinct overrepresentation of women on their pictures, but also in terms of the authors of the articles.

Höghöjdsanpassning av BvS10 : Konceptstudie för optimering av överladdningssystem

This report relate a concept study that consider a number of different proposals to improve the overcharging system in BAE Systems Ha?gglunds tracked vehicle series BvS10, to maintain sealevel power at extreme altitude.At high altitude the power losses beacuase of the air density that decreases, which results in less fuel can be burned. The decreasing of air density also gives rise to fatigue failure of the turbocharger unless power is reduced.The proposals shall be as required by BAE Systems Ha?gglunds economically sustainable and defensible from a packing perspective. That means the selected solution must have a reasonable price tag and at the same time a minimal impact on adjacent components.The basis for this thesis is based on benchmarking of both the auto industry as the flight industry, to find inspiration and tips for improvement.Some of the concepts have after gathering facts and calculations been excluded while other solutions has been considered as workable and thus interesting for BAE Systems Ha?gglunds.Initially the current turbochargingsystem was analyzed in order to determine the starting point and thus be able to fix the current problems surrounding high altitude driving.

Analys av spänningsstabilitetsberäkningar i det svenska elsystemet

Numerical simulations play a vital role in both static and dynamic stability assessment of electric power systems and the foreseeing of voltage collapse. Simulations performed by Svenska Kraftnät(SvK) are mainly done in the specialized voltage collapse predicting software tool, SPICA and the more all?purpose software tool, ARISTO.The grid operators at SvK use SPICA to predict the maximum transfer limit at specified sections (in this report the section in concerns is the southern part of Sweden i.e. interface1 4). SPICA is mainly used as an online application by using actual states from the grid, these states update every quarter of an hour.This thesis is a continuation of the master thesis SPICA ? ARISTO JÄMFÖRELSE by Jakob Katzman and Johan Fält.

När handling säger mer än ord

The purpose of this paper is to present a possible understanding of why the company Tekola is segregated according to sex. In accordance to this purpose, an understanding of how the segregation affects the employees in relation to power, values and possibilities is discussed. The theoretical understanding is that the organization of men and women within Tekola is done in close connection to creation of the meaning of gender in Tekola. This, in turn, affects and is affected by the recruitment to and within the company. Through the study of statistics from a survey, five interviews with employees and former employees and Tekolas? equality plan, we are able to see the possible existence of a glass ceiling, and a culture of homosociality, which affects the possibilities of women to enter the company and also to gain full entrance to power-positions in a negative way.

Störs laxens lekvandring i en kraftverkspåverkad älvsträcka? :

The upstream spawning migration of Atlantic salmon (Salmo salar) at the confluence area between the power-station outlet and the bypass-channel in river Umeälven (flow 430 m3s-1) was compared in 2004 and 2005, two years with different experimental flow-regimes. In 2004 the water flow in the bypass-channel was altered during the day with increased flows during the nights while the water flow in 2005 mainly was altered between the weekdays and weekends. Salmon showed altered migratory behaviour in this confluence area, assessed with telemetry (n=116) and echo-sounding, with up- or downstream responses depending on flow-changes in both the bypass and the power station outlet. Increased turbine flow through the power-station generally attracted salmon into the tunnel outlet area while increased spill-flows facilitated salmon to enter the bypass. Echo-sounding in the confluence area showed an increased swimming activity up- and downstream due to time in the day and flow-rates through the tunnel outlet. No changes in activity could be detected due to increasing or decreasing flow through the hydro-power facility.

Monitoring and pest control of Fruit flies in Thailand : new knowledge for integrated pest management

Fruit flies (Tephritidae) are serious pests that cause enormous losses for farmers in many countries. The frequent use of insecticides in controlling fruit flies in fruits and vegetable has not resulted in sustainable management of the pest. Problems associated with this complete reliance on chemical control are many residues of insecticides in crops, health problems for farmers, contamination of water and soil, insecticide resistance development and decrease in natural enemy populations. The implementation of control measures that do not imply an added burden to the environment and/or the farmers is urgent. More knowledge about the ecology of fruit flies is the basis for finding new and better ways to control this pest.

Anställdas attityd till miljön och miljöledningssystemet: ALSTOM Power Sweden AB

Today environmental management systems (EMS) are common documents (more correctly, a combination of documents) that direct, steer and regulate environmental efforts within many companies. The intention of EMS is that its guidelines are reflected in how the employee carries out his everyday work tasks. This study aims to illuminate the attitudes that exist regarding the EMS at ALSTOM Power Sweden. By using questionnaires and interviews as a method to communicate with employees,a study of the existing attitudes regarding the EMS was carried out. The results were analyzed categorically and statistically and show that there are consistent attitudes among employees, but that there are also inconsistent attitudes.

Hur enkel- & dubbelportsturbin i kombination med två olika avgassamlare påverkar gasväxlingsprestanda på en Scania V8

The exhaust arrangement on a Scania V8 consists of one manifold at each bank connected to a twin entry turbine (8-2-2). A study in GT-Power has shown improved performance and reduced cylinder to cylinder variations using two manifolds at each bank in combination with a single entry turbine (8-4-1). This thesis work analyses the difference in performance shown in simulation and verify it by engine test.The initial work was focused on simulation in GT-Power. Investigating how exhaust manifold volume and pulses effects the turbine efficiency and the mean effective pressure during the gas exchange. To verify GT-Power simulations four engine tests with different exhaust arrangement have been made.The results from GT-Power simulation indicate that a larger exhaust volume improve the turbine efficiency.
