Experimentell konstruktion av pickupsystem anpassat för trummor med hjälp av MATLAB

For several years Uppsala University together with several companies has been involved in a WISENET project aimed at improving railway transport security. By placing a sensor system near the wheels of each wagon, the temperature of the bearings can be measured and transmitted to a collector placed centrally on the wagon. This in turn transmits the collected data to RFID receivers placed intermittently along the railway.As the signals are transmitted wirelessly, problems may occur as the antennas get dirty or coated with ice and snow. To determine the effects of these coatings, several tests were performed examining the reflection coefficient S11, the impedance Z11 and the efficiency eta of an antenna, and how they varied when various coatings were placed over the antenna. Examined coatings were ice, snow and water to determine the effects of weather, and various metal-based coatings: powdered iron both pure and partially oxidized, and iron ore granules.

Spelar skolbiblioteket någon roll? Hur elever från grundskolans år 9 söker, finner och väljer ut information till egna fördjupningsarbeten

The Swedish working-class author Ivar Lo-Johansson (1901-1990) wrote a collection of one hundred short stories between the years 1968-1972. His other productions, generally speaking, have partially different social reform purposes, but, according to himself, these short stories were written with the intention to be totally free of tendencies (even though he himself doubted that he succeeded with this).During the same period that these short stories were published, the Swedish social democrats were under the challenge of radical movements that, mainly on the radical left?s ideological foundation, had a relatively strong influence in Sweden, among other countries, from the mid 1960?s to the late 1970?s. Since Lo-Johansson mainly seemed to have supported the politics of the social democrats, the purpose of the investigation in this thesis has been to see if he ? in the three short stories: Vikingakärlek (1970), Rikslögnaren (1971) and Ansgars resa till Sverige (1972) ? is conveying an ideological use of history and basic political values that were used by the social democratic party during this time period.

Reflektion i förskolan : en vetenskaplig essä om den handledda reflektionens nytta och skada i förskolan

The purpose of my essay is to highlight the various dilemmas that can occur in the preschool during the moments of guided reflection but also the opportunities it can provide. I am using my own practical experience from situations where care for the children can be questioned and needs to be considered in comparison to the further development of the preschool teachers and with them the entire organization. In my research, I have chosen to highlight the importance of guided reflection, the importance of reliable and secure relationships for children and how these can be eradicated, and finally the importance of ethics for the preschool-teacher?s actions in a given situation.Key questions in my text are; What role does the reflection have in the work at the preschool? How are children affected while this is happening? How important is close and secure relationships for young children and how can they be affected? How can one find a balance between care and learning?By writing my essay I reflect on myself and my own actions. This leads me to a greater selfawareness and greater understanding of my own feelings and my role in the dilemmas I face in my profession.The conclusion of my work is that the preschool organization is not given and it can be constructed in many different ways.

Varför dela makten? En studie av consociationalism och Democratic Unionist Partys beslut att delta i regering på Nordirland.

On the 8th of May 2007 a local power-sharing goverment consisting of Sinn Fein and the Democratic Unionist Party (DUP) was formed in Northern Ireland. The aim of this dissertation is to explore why the DUP, who in the past have opposed all forms of power-sharing decided to form a goverment and take active part in a power-sharing agreement. The study is based on a consociational theoretical framework developed by Arend Lijphart and further developed in a Northern Irish context by John McGarry and Brendan O'Leary. Using this theory the study seeks to understand the broad conditions surrounding the DUP's power-sharing. After a description of consociational theory and the road leading up to the Belfast Agreement,three possible explanations for power-sharing, based onconsociational theory are discussed.

SSD - Stair Support Device

Together with Hälsoteknikalliansen the project team recognized the need to improve availability in the staircase environments. This is a difficult environment, especially for our elderly. The staircase leading to and from apartments is such a major obstacle that many people do not dare to go into the staircase leading to their front door. The market study that the project team conducted showed that many were in need of a living support, often a relative, who helped and supported them when they went into these stairs. It also appeared that these people manage everyday life just fine, but they suffer the problems that stairs to and from their apartment causes.
