Överföring av elektrisk signal och effekt med magnetisk induktion.
This report tested the possibility of using induction as a mean for transferring data and power so that it can be implemented as a communication medium between a terminal and measuring head mounted in a measuring frame. This would eliminate the need for the cable bunches that are used today. For testing, signal generators were used to generateFSK-signals and were transferred with the help of inductors to the oscilloscope for signal detection, this to see how the coils used in the tests behaved. Simulations of a PLL were performed to see how good it could handle FSK-demodulation. With the help of a PLL IC and the simulations a working FSK-demodulator could be assembled.
Digitalt utbildningshjälpmedel : Interaktiv karta för utvärdering av militära övningar
Precis som titeln avslöjar handlar rapporten om att utveckla ett system som kananvändas vid utvärdering av övningsmoment. Idag saknas ett liknande system somvara ett stöd för hemvärnets instruktörer vid utvärderingar som har till syfte att ökaförståelsen hos övande personal. Systemet består av en mobilapplikation och enwebbapplikation. Mobilapplikationen loggar hur en soldat har framryckt under ettövningsmoment och sedan sammanställs data från en eller flera mobilapplikationer ien webbapplikation där data visas på en interaktiv karta. Kartan ger möjlighet attstega sig igenom händelseförloppet.
Att leva med missbrukare : En studie om medberoende kvinnor från Sydostasien
The purpose of this essay was to examine female immigrants of South East Asia who have lived together with a drug addict and how they were affected and let themselves be influenced by that, and to study their reactions to such situations.The main questions were:· How do the women describe their personal relationship matters with their husbands with focus on abuse / co-dependency?· How do they show their co-dependency in actions?· How do the women handle their co-dependency?I chose a qualitative method because my purpose was to get a comprehension and hopefully find a pattern in the life situation in this specific target group. Regarding the collection of dataI used both primary data in the frame of interviews with persons connected to the problem, and secondary data in the form of earlier studies in that field.As the main result I found that these women lived in a severe stress. They were affected both psychically and physically by the abuse of their partners. They developed different strategies of survival to stand the reality and to save the family.
Detektering av in- och utandning vil bilkörning med hjälp av Matlab
Volvo Human Monitoring (VHM) is an ongoing project at Volvo Cars where they measure, amongst other parameters, inhalation and exhalation through a device called Respiratory Inductance Plethysmograph (RIP), on drivers. RIP measures changes in the cross-sectional area of the chest and abdomen. When the driver is in motion, such as when she is turning the vehicle, the cross-sectional area changes and noise in the RIP signal may arise.The noise results in a large number of manual adjustments in the analysis of the RIP signal, which is very time consuming and the validity of the device for measuring inhalation and exhalation is questioned.The purpose of this study was to improve the efficiency of the analysis of the RIP signal. The goal was to create a new data processing tool in Matlab that automatically detects inhalation and exhalation from a RIP signal with higher validity compared to the previous data processing tool.In this study, nine tests were performed on drivers while they were driving in different scenarios such as highway, country road and in city traffic. Inhalation and exhalation was measured using a RIP, a pneumotachograph with a tightly sealed facemask and a thermocouple placed between the nose and mouth, which was used as reference to the RIP.The result of this study was a data processing tool that automatically detects inhalation and exhalation with higher validity compared to the previous data processing tool.
Verktyg för hantering av kommunala VA-data
Inom ramen för projektet ?Kiruna referenskommun? har Tekniska Kontoret gett i uppdrag åt Metria IT i Kiruna att utarbeta en applikation i ArcView för hantering av det kommunala VA-nätet. Uppgiften för detta examensarbete var att bygga en del av applikationen. Arbetet inleddes dock med en förstudie av alternativa system för ledningshantering. Bland andra kan nämnas KORDAB och Vabas/Duf vilka båda är specifika VA-program med ett omfattande antal funktioner.
Hantering av specialservice för DHL
In order to measure the quality of the logs, one can with help of Fast Fourier Transform technique get the signals resonance peaks. With help of these peaks you can see whether the quality of a tree is good or bad. This report contains the work of a where a program has been developed to be able to process a vibration created by an automatic hammer hitting on a log of wood. From the processed signal the program should be able to show both the raw wavesignal and the processed measured data from the resonance peaks. Beyond the raw wavesignal and resonance peaks the program should also be able to control the automatic hammer.

En kvalitativ studie av lärstrategier och perceptionsmodeller inom kemiämnet på gymnasie- och högskolenivå med fokus på de laborativa momenten
The aim of this study is to investigate how chemistry teachers at secondary school anduniversities work with learning strategies and models of perception. This thesis leans on theworks of Lev Vygotskij and his likes but also on the theory of conceptual metaphors by GeorgeLakoff and Mark Johnson as a tool to analyze the collected data.The Empirical data that this study is based upon have been collected through semi-structuredinterviews with teachers as primary respondents.The study has resulted in a two practical assignments for secondary school which are builtaround the concept of open assignments. This thesis has also generated a suggestion for a newstructure of the bachelor programme in chemistry at KTH..
Bergkyla och bergvärmeutredning för industrilokalen Rödbergsmyran 5 i Umeå, Västerbotten.
Grubbe Ventilation AB is a sheet metal and ventilation company who provides design, installation, service, and repair of ventilation. The company is expanding their business by building a new facility in Umeå, Västerbotten. The property is designed to be used for both office and industrial work.Grubbe Ventelation AB has not yet decided upon wish system which is to be established to provide the building with heating and cooling. The consulting firm Umeå Projekt Team has therefore been asked to investigate the possibilities to invest in geothermal- heating and cooling.If the investigation of a geothermal heating- and cooling system would provide favorable results it would be a very appropriate alternative that provides energy at low costs and are an environmentally friendly option as the energy comes from stored solar energy in the ground is provided by stored solar energy in the ground.The facility ´s heating and cooling consumptions are calculated in the program BV2 and the result indicate a heating demand of 185 000 kWh per year due to thermal transmittance, transmission losses, heating of warm water and a cooling requirement of 5500 kWh.Three different systems of geothermal heating and cooling were tested in the computer program Energy Earth Design. The results show no difference in the dimensioning of the drill hole if merely heating were to be used or both heating and cooling were to be established.
Implementering av PostgreSQL som databashanterare för MONITOR
Monitors affärssystem MONITOR är under ständig utveckling och i och med detta ville man kolla upp huruvida PostgreSQL skulle kunna användas som DBMS istället för det nuvarande; Sybase SQL Anywhere. Examensarbete har därför bestått av en jämförelse hur PostgreSQL står sig jämte andra DBMS:er, en implementering utav en PostgreSQLdatabas som MONITOR arbetar mot samt ett prestandatest utav skapandet av databasen.I många avseenden verkar PostgreSQL vara ett alternativ till SQL Anywhere;Alla datatyper finns i båda dialekterna.Backup av data finns i olika utföranden och går att automatisera.Enkelt att installera och uppdatera.Ingen licensieringskostnad existerar.Support finns tillgänglig i olika former.Dock så är inte PostgreSQL ett bra DBMS att byta till i dagsläget då systemet inte fungerade på grund av att vissa uttryck inte översattes ordentligt samt att ingen motsvarighet till LIST existerar. Ännu större är dock problemet med tiden det tar att flytta data till en PostgreSQL-databas då det inte är intressant att lösa problem med funktioner i systemet om det ändå inte går att använda på grund utav att konvertering av data tar så lång tid som det gör..
