Design och utvärdering av power system stabilizer isynkrongenerator

The purpose of this report was to investigate what characterizes a good psychosocialwork environment, and whether it may have impact on a vessel's safe voyage. Thisreport is proposed to increase the understanding of what creates a good psychosocialwork environment and its potential effect on safety at sea. In order to find out thesuccess factors for a good work environment group interviews were conducted in socalledunstructured focus groups. During these conversations, the participants discussedfreely by the question "what is a good psychosocial work environment for you?? Thesuccess factors were thereafter applied on selected accident reports, to investigate theextent to which they were represented and taken into account.The results of the study show three categories of factors: colleagues, communicationand competence, where colleagues are the main contribution to a good psychosocialwork environment.

Döden som rituellt medel

This essay consider ritual death during the ironage, and through a presentation of historical and archaeological sources. Considered ritual death I think we should study both historical and archaeological sources, to get a vider view and a new perspective. To make the essay easier to understand I have split up the early and the late Iron Age in the discussion. In order to study the ritual death I have shown archaeological examples like bogsacrifices in the early ironage, and decapitated victims in the Viking society. The victims have been considered as slaves by some archaeologist.

Demand and economic potential for working horses in Swedish municipalities

The aim of my study is to answer the question whether there is a potential for services by working horses in the Swedish municipalities. The Swedish University for Agricultural Sciences (SLU) and Swedish Farmers Union (LRF) has started a cooperation called Climate School (Klimatskolan), with the purpose to increase knowledge in environmental and climate related issues in context of agriculture. This Master thesis is in the framework of the Climate School.Global warming is a problem that gets much attention today. Global warming and climate change are two subjects that are very much in focus on the political agenda. The municipalities of Sweden have a big responsibility concerning environmental work and to develop their own environmental thinking.

Hur påvekar författares föreställningsramar och arbetsmetoder det arkeologiska materialet och dess framställning? - En exemplifierande jämförelse av två författare

This essay is comparing two authors and the way they make use of and explain some of the archaeological methods and artifacts through their books.The first author is the Swedish archaeologist Stig Welinder, who has written Jordbrukets första femtusen år (The First Five Thousand Years of Agriculture). The second author is the American archaeologist and writer Adrian Praetzellis, who has written the book Death by Theory.These books are very different in some ways, but not in others. The main difference is that Death by Theory is belles-lettres while Jordbrukets första femtusen år is science.Both authors explain and in some way apply the use of the terms ?artifact? and ?ethnoarchaeology?, which is the two main subjects of comparison in this essay. The way they present these subjects, through their different styles of writing, is compared and discussed.

Windbelt

Radio Frequency Identification, RFID, is a convenient way to enable contactless identification which does not require any physical nor optical contact. As with any radio-based communication the signal can be intercepted, thus making the technology vulnerable to several kinds of attacks. Interception of communication is not the only threat. Since RFID tags might contain personal information or information that will grant the owner access to secure areas, skimming and spoofing attacks are also major threats against this technology. In this thesis report,  the perspective of an adversary is portrayed in an RFID-enabled environment by presenting where RFID is used and how it could be abused.

Fo?rstudie fo?r automatisering av skateboardtillverkning

This report is based on a thesis that was carried out during spring 2012. The report covers the development of a preliminary study to Performance Sk8. The purpose of the study is to facilitate and contribute inspiration to Performance Sk8 to run an automation project to bring home their production to Sweden from China. The reason is to gain a greater ability to control quality, produce smaller batches and reduce the cycle time to reduce costs.The goal is that the preliminary study shall meet the requirements and wishes Performance Sk8 and other partners defined. The pre study will contain different cost proposals for the automation of selected process and serve as a basis for procurement of the equipment.The pre study has resulted in some proposed solutions to the various steps required to automate Performance Sk8 ?s production.

Konstruktion av mutterdragare för stora moment

This degree project was conducted in collaboration with Gremo AB located in Ätran.The aim of the project was to develop a solution to secure quality and to help assemblingthe locknut holding the vertical hinge on the harvesters and foresters from Gremo.At this time the nut is assembled manually by the aid of an overhead crane. The nut istightened differently from time to time, and there was no specified torque to which it istightened. Another present problem was the locking washer which sometimes getsdamaged during assembly, when this happens the procedure has to be started over fromthe beginning. The current assembly procedure is very time consuming and lengthy forthe employees.Our task was to design a machine that could tighten the nut to a specified torque with amargin of error of ± 3%. The assembly procedure will be held simple and the timerequired at a minimum.The project started by developing several principle solutions, the one solution that bestmatched our specifications were developed to a primary solution.Today we have started manufacturing and assembling our prototype.

Konduktivitet i vattendrag som indikator på sura sulfatjordar

Increasing attention is being given to acid sulphate soils wherever they occur. The problems that leaching sulphate soils gives with significant lowerings of pH and mobilization of heavy metals influence large spectra of our society from fisheries to agriculture to construction. Mapping these soils is consequently of great importance and the methods of doing this is very much lacking in function and precision. This study was therefore carried out to investigate whether conductivity in running water can be used as a simple instrument to identify acid sulphate soils in the catchment. 31 coastal streams in the county of Västerbotten were analyzed for different catchment properties such as occurence of marine sediments and basic water chemistry including conductivity and sulphate.
