At Uppsala university scientists have during the last years developed and built wave energy converters. This project is called "Lysekilsprojektet". The development has come so far that they are currently investigating how to gain profit in a mass production. For that reason they want to automate as many steps in the production as possible.The winding of the stator is one part that is being automated using industry robots. The stator is cable wound unlike many other generators.

AbstractConsider a ?uid being heated from below. The heating leads to an upward convectiveforce that is counteracted by the viscous forces of the ?uid. If the convectiveforce is large enough in comparison to the viscous forces the ?uid will be put in anunstable state.

The aim of this study is to provide an investigation of an ?old? political phenomenon that over the recent years has enjoyed a considerable revival across Europe. This study about nationalism is mainly based on empirical second hand source material from literature and articles providing us with both a historical as well as a contemporary insight in this ideology. This study shows us the complexity and the difficulties that the academia is facing regarding nationalism due to the dynamic nature of the ideology, in the sense that it simply means different things to different peoples in different cultures across different points in time. The study is conducted by using a phenomenological, qualitative and inductive method of gathering and interpreting information.  A handful of books have formed the foundation through the gathering of relevant empirical information, along with articles from both scientific publications as well as the mainstream media. The data have been studied and laid out to make key points regarding nationalism and the theory behind it clear for the reader.

Background: Insufficient nutritional support is associated with prolonged hospitalisation, impaired wound healing and impaired survival for patients in intensive care. In severe sepsis and septic chock, calculation of nutritional need is complicated since the metabolism is affected by decease. Aim: The aim of the study was to investigate nutritional support and to examine the quality of nursing documentation of nutritional status and nutritional support in patient records in severe sepsis and septic chock.  Method: The study was conducted as a retrospective investigation where 64 patient records were studied. The quality of documentation was examined in 10 patient records using an examinational model.Findings: Calculation of average nutritional support showed insufficient supply particularly in the two first days of intensive care. During the next five days nutritional supply was higher but individual variation was seen, why a clear picture of nutritional support is hard to detect.

Den här uppsatsen redogör för en studie om ledningens roll vid postimplementering avaffärssystem. Syftet med studien var att belysa vilka faktorer som bidrar huruvidapostimplementeringen kommer bli ett prioriterat område i verksamheten. Studien syftadeockså till att ta fram riktlinjer som kan vara behjälpliga för ledningen vid genomförandet avpostimplementeringen. Studien består av en teoretisk referensram, som är uppdelad i tre olikadimensioner: ledning, organisation, system. Vi har i studien gjort en förstudie och enhuvudstudie.

Gliding and sealing functions in Öhlins shock absorbing systems sets great demands onthe contacting surfaces. In this particular case, the bushings and the sealings on acylinder piston. The surface wanted is a surface with both low frictional forces and smallleakage. This study was done with the goals of investigating and determining existingsurfaces due to the frictional force and leakage. How can we in an easy mannerdescribe these?A number of ten front forks were part of a main study.

In 2007 Swedish Meats, the dominant Swedish meat-producers cooperative sold its slaughtering and processing industry. The goal of a producer cooperative structure is to create value for members through vertical integration, and to strengthen members? market position. When Swedish Meats sold the slaughtering and processing components, it ceased in some respects to serve the function of a cooperative. This is a lost opportunity for both members and non-members, because Swedish Meats as a functioning cooperative could have exploited its dominant market position to positively effect producer?s prices.

The goal of this thesis is to analyse whether the method ?Observiaire? is of any use for traffic analysis. The method consists of analysing film material, preferably before and after changes are made to an area, by answering a survey for the users that are observed within the population. The method also opens up for deeper qualitative analyses which are rooted in the quantitative data collected from the survey-study. In this study we analyse the method by applying it to the case study of the changes made at Götgatan in Stockholm, where a green wave was implemented and the bicycle road widened.

Denna komparativa studie behandlar de faktorer som spelat in i militärregimernasfall i Grekland och Argentina. Som teoretiskt ramverk för analysen utgår vi ifrånO´Donnell och Schmitter "Transitions from Authoritarian Rule" samtHuntingtons teorier i "The Third Wave". Studien är av "mest lika design", varssyfte är att finna de faktorer som de båda transitionerna delar, för att därmedkunna dra generella slutsatser om faktorer bakom militärregimers fall.Resultatet visar att bakomliggande faktorer i de båda fallen ärlegitimitetsproblem, liberalisering, civil society, liberalisering, hard och softliners,mobilisering av civila politiska aktörer, samt de slutgiltiga militära nederlagensom transitionsutlösare. Studien visar att den viktigaste av dessa faktorer ärlegitimitetsproblemet, eftersom denna faktor på ett eller annat sätt är kopplad tillövriga. Vidare visare studien att ekonomisk instabilitet spelar en stor roll imilitärregimernas fall, vilket inte lyfts fram i teorin..

Den här studien handlar om användarkompetens vid postimplementering av affärssystem.Syftet med studien var att belysa vilka faktorer som påverkar om användarnas kompetenskommer att omsättas till effektivare nyttjande och användande av affärssystemet. För attkunna göra detta har vi kartlagt hur ett antal företag arbetar med dessa frågor. Studien syftadeockså till att ta fram riktlinjer för hur företag effektivt bör hantera och utveckla användarnaskompetens under postimplementeringen. Studien består av en teoretisk referensram, som äruppdelad i fyra kategorier; ledningens roll, kompetensplanering, kompetensutveckling ochanvändarmedverkan. Vi har i studien gjort en förstudie och en huvudstudie.

The concept of vulnerability is the capacity or the sensitivity to become damaged. Vulnerability are characterized by one or more of the following terms; a system´s sensitivity to exposure to shock, stress or interference, the state of the system in relations to a threshold of damages, and the system´s ability to adapt to the changing circumstances. Vulnerability in this study is referring to the sensitivity of the circumstances that lead to sustainable livelihood that can´t be maintain and that there is an inability to cope with and manage stress. The choice of making a study in this area is based on that action needs to be taken to moderate the vulnerable aspects of society, in this respect in relations to storms. Analyzes of the social vulnerability to climate change or natural events is needed for effective actions.

This bachelor thesis is about an ultrasonic sensor, implemented in a bubble chamber in Artis. The sensor consists of the piezoelectric sensor and an electronic control circuit. The control circuit consists of a programmable microprocessor, PIC18F2420 and a circuit, which sends the excitation signal to the piezoelectric sensor, and later receives the echo. This bachelor thesis consists also of a theoretical study, which examines different techniques of liquid level sensing in a chamber. The study discusses which factors are important in liquid level sensing and examine accepted methods.
