Deep Green i oceana strömmar - en konceptstudie

With growing economies and better living standards in many parts of the world today, there is a need of expanding the capacity of generating electricity. The alternatives for renewable energy technologies are not fully developed and have still some problems to conquer.The company Minesto has developed a technology that is called Deep Green. It is designed to gain electricity from tidal currents. Deep Green works in a similar way as a kite that is attached to the seafloor with a moving wire. It contains of a wing that moves due to the water current.

Kvalitetssäkring

This thesis has been made in cooperation with Forsheda Stålverktyg AB which develops and manufactures injection moulds and diecasting tools. The main concern has been their Trading-system which provides them with considerable amount of quality lost function.Focus has to however be put on the analysis of the Trading-system due to the fact that this has previously meant various quality issues for the company.This thesis treats quality assurance of the Trading-system, identification of the problems in the process and improvements of these problems.Quality assurance is carried out when a company detects that their quality based costs become too high. Quality based cost are? the costs that would disappear if a company's products and its different operational processes were absolute? (Sörqvist, 2001 p.30, free translation from Swedish). High quality based costs often result in increased quality problems, which can lead to substantial economic loss for the company.This work has resulted in a thorough review of the Trading-system whereupon problems have been identified.

Vindkraftens påverkan på lokalsamhället : en fallstudie

The purpose of this thesis is to investigate how a local community, and those who dwell within its borders, are affected when a large scale windmill park is planned in its immediate vicinity. I have used a qualitative approach and conducted semi structured interviews to gather empirical data. The study took place in a small Swedish village named Svartnäs, situated in the region Dalarna.I have used the concept of community as a symbolic construction (Cohen 1984), that together with the theory of structuration (Giddens 1984) and the notion of expert system (Giddens 1996) served as my main theoretical perspectives.Even though the windmill park is not built yet, its impact on the people and the local community of Svartnäs has been considerable. In the traces of the new windmill park new options and constraints, that will play an important role in the lives of the people who dwell in Svartnäs, are arising. The windmill project is enlarging old conflicts and is creating a divided village.

Lagring av flisade skogsbränslen : - med avseende på att minska energi- och kvalitetsförändringar

Computer based information systems play an important role in modern military combat vehicles. The crew needs to be able to quickly get information about both the vehicle and its outer surroundings in order to quickly make the correct decisions. In this report, we describe the development of a prototype new information system for the BvS10 vehicle, manufactured by BAE System Hägglunds AB in Örnsköldsvik.An important aspect of the system is the time it takes from the point that the information is generated by the vehicle sensors until it is presented to the user. The system must be able to ensure that it never displays information that is out of date. Thus, it is important to create a layer and component based architecture for the solution, making it possible to control, in detail, the information?s age as it moves through the system.

Diagnostik för mjukvara, en ny trend?

Detta examensarbete beskriver utvecklingsprocessen och implementaionen av delar av ett sådant system. Rapporten behandlar också till viss del diagnostikverktyg som finns idag och lite om hur framtida system för att underhålla datorsystem kan se ut..

Att sjunga en fråga. En jämförelse av tre Query-by-Humming-system och deras användare.

The aim of this study was to compare the Query-by-Humming systems Midomi, Musicline and Tunebot regarding their retrieval effectiveness. The aim was to see if there were differences between the systems but also between the user groups common users, musicians and singers. Query-by-Humming system means that the user sings a tune that the system then use to find the right melody.To compare the systems and their users, queries where collected from the different user groups and replayed for the systems. Mean Reciprocal Rank and Friedman test was used to do the comparison.The results showed that the system did not achieve equivalent and that there were no difference between the user groups. The Mean Reciprocal Rank showed that the systems had very different retrieval effectiveness, where Midomi was the system with best result and Musicline with the lowest result..

Översvämningsmodellering av ett dagvattensystem

Storm water management has become a more important matter as urban areas are expanding and natural areas are being exploited. As nature landscapes are being converted into hard surface areas storm water flow is affected both in terms of velocity and size. A flow increase can easily result in a flooding if the dimensions of the pipeline system are inadequate. Considering predicted upcoming climate changes, flooding?s may become more common in urban areas in the future.

John A Wardens teori om fienden som system applicerad på Al-Qaida

Den amerikanske flygvapenöversten John A Warden III har lagt fram en teori om att man kan se på fienden som ett system av system för att hitta hans svagheter. Teorin bygger på att skapa en bild av fienden genom en fördefinierad indelning i subsystem bestående av fem ringar. Denna bild skall därefter kunna brytas ner i ytterligare subsystem bestående av samma fem ringar som till slut avslöjar fiendens tyngdpunkter. Uppsatsen prövar om Wardens teori går att applicera på Al-Qaida..
