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.

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..

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.

Background: Sleep-disturbances in persons with Alzheimer´s disease are prevalent. They are characterized as increased frequency and duration of awakenings, decreased slow-wave sleep, REM-sleep and increase of day-time napping. Depression and lower quality of life are associated with sleep-disturbances. Altogether a significant source of stress for caregivers and an important factor in institutionalization. Non-pharmacological treatment alternatives are rare.Method: Single-case A-B-C design, with non-concurrent multiple baselines, a pilotstudy.Aim: To explore if an educational program on sleep, sleep disturbances and behavioural change directed towards caregivers improved sleep, depression and quality of life in persons with Alzheimer´s disease living at home.

Orust Kretsloppsakademi is a nonprofit organisation, with a goal of annually generate the same amount of electrical energy that is consumed. Orust is an island on the west coast of Sweden, north of Gothenburg. The population of 15 000 reaches 40 000 during summer, due to the large amount of vacationer. The total electricity demand is 174 GWh a year with a maximum power need of 32 MW. This report presents an analysis for the plausibility of their plan and from a power system stability perspective, the effects on the electrical grid.The conclusion is that the restraints for development of power generation from wind, solar and wave generation, are the power systems capability to transfer power, primarily in the transformers of the grid.

This thesis work includes studies and simulation how magnetization of the translator in a linear generator for wave power can be automated. The translator is the moving component in the generator that is "dressed" with permanent magnets. The translator is magnetized with rectangle-shaped permanent magnets that are today's strongest permanent magnet type of neodymium-iron-boron (NdFeB).Eight equivalent metal sheets are mounted around the translator. The plates have milled tracks where 106 permanent magnets per sheet are mounted. Today the assembling of the magnets is done by hand, which is a very tedious and time-consuming work.  This project presents investigations about the automation of the translator magnetization theoretically and simulation results are preformed in ABB's robot simulation software RobotStudio. Even robot-held tool was designed that enables the robot to be able to magnetize the translator in a simple manner.  The investment cost is roughly 1.5 million SEK. With an economic life-time of five years, the investment costs are estimated to 24000 SEK / month.  According to the calculations, this project is very motivated to implement, as it provides savings up to 17 000 SEK per translator which is 10.2 million SEK assuming that the robot cell is operating at full speed the whole year.According to this thesis work the result is a 4x9 meter cell with two industrial robots of the type ABB IRB6650S.The cycle time to magnetize one translator was calculated to about 10 hours.This prototype of project can possibly be implemented in a full-scale production line and performed according to the calculations and simulations presented in the report. Further work is suggested to improve the tool.Lyssna .
