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.

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.

Hållbarhet handlar om att främja välfärd nu, och i all tid framöver, genom att ta hänsyn till egologiska, sociala och ekonomiska aspekter. Det handlar om att tillgodose dagens behov utan att förstöra möjligheterna för kommande generationer att tillgodose sina.Vårt examensarbete undersöker förutsättningarna för hållbar möbelproduktion. och vi gör detta genom ett flödesschema som skall användas vid uppstart av hållbart producerande företag. Idén bygger på att råvarorna utvinns och förädlas inom en femmilsradie.Vi hoppas kunna åstadkomma en djupare relation mellan användaren och objektet än vad endast köpande och ägande ger. Vi har valt att tydliggöra konstruktion och uppbyggnad, samtidigt som formen uppmanar förnuftet till kritiskt ifrågasättande av stabilitet och hållbarhet både konkret och i ett vidareperspektiv.

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.

Hand raising is a common method in schools and a way for students to engage in the classrooms turn-allocation (Andersson & Haglund 2006, p 35), but not all benefit from it. According to Dylan Wiliam (2011) hand raising divides the students by putting the students that participate in hand raising at an advantage versus the students that do not. This study aims to examine hand raising as a phenomenon and the students and teachers thoughts about hand raising. The main research questions were:How do the students perceive hand raising?How do the teachers reflect upon hand raising?How is hand raising usedas a tool by the students?The main reference to this study has been senior lecture Fritjof Sahlströms (1999) thesis Up the Hill Backwards.

Results have shown that flow batteries may be a solution in the future as an effective and environmental friendly method to an energy storage system (ESS). The technology is reliable and has a high efficiency that comes with low energy losses and a long lifetime. The range of possible fields is suitable for cutting energy peaks in the power grid, by always have a ready and available energy storage that balances the production. By comparing the advantages of flow batteries with conventional batteries it is mainly the fact that they can conserve energy for a long time without being self-discharged thanks to that the storage capacity is in principle endless and limited by the size of the electrolytes tanks that makes them a great energy storage system. The batteries won?t take any damage or decrease in performance when charging or discharging it or if you exhausts it to 100 % and leave it discharged for a long time.

The competition has increased with the establishment of the new banks and the credit institutes taking on the market, the big banks are no longer alone on the market.In speed with the increased range, have also the marketing and the recruit of new bank customers become more driven.Bank customers with lacks in the Swedish language, is a segment with potential which doesn?t get used by the banks and in turn of that the bank customers doesn?t get their needs satisfied.The purpose with this survey was to analyze if the four largest banks, Föreningssparbanken, Handelsbanken, Nordea and SEB had prepared strategies that were directed to bank customers with lacks in the Swedish language. In those cases the banks had strategies, respective measures were presented.Furthermore the bank customers with lacks in the Swedish language were studied if they experienced that the banks were using measures to satisfy their language needs in contact with the banks and presented the benefit of them.The information about the banks strategies was assembled through interviews with persons from each bank. The bank customers experience was assembled through a questionnaire survey.The result showed that the banks hade different strategies for reaching out to these customers, it was from showing understanding to multicultural offices. Half of the customers appreciated that the banks pressured themselves for them by being patient, explained the services and in some cases had staff that could several language.

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..

The purpose of this essay is to explore the actor network of a high technology company in the textile industry called F.O.V. Fabrics. The background for doing this is a recent project, which we choose to call the Salt & Paper Battery Group, aiming to commercialize a newly discovered technology ? a battery based on cellulose from an alga. We start by examining a range of network theories in order to eventually shape a framework of our own.

Det kommande innehållet i detta examensarbete kommer att handla om min frågeställning som berör integrering av 3D objekt i en verklig miljö: ?Vad finns det för metoder att integrera 3D objekt med en verklig miljö och hur gör man??.Arbetet och efterforskningen har utförts i Söderhamn, där jag har arbetet hos 3D animationsföretaget Magoo 3D Studios. Med hjälp av anställda på Magoo har jag genomfört experiment för att själv prova på de olika metoder som ska kunna besvara min frågeställning.Som resultat så har jag kommit fram till att alla divisioner inom 3D, som modellering, texturering, ljussättning och compositing kan bidra till realistisk integrering på sitt eget vis, dock i olika utsträckningar. Mina experiment har alla varit lyckade och jag känner att de är på rätt väg mot fotorealistiska resultat.I slutändan så upplever jag att de metoder som bidrar mest till en realistisk integrering är en bra ljussättning med en Image Based Lighting metod, samt att ha bra vetskap om hur en kamera fungerar för att sedan kunna efterlikna dess typiska drag samt artefakter så bra som möjligt.Kombinerar man dessa metoder så är man en bra bit in på vägen till fotorealism där man inte längre är säker på om datorgenererade bilder är riktiga eller inte..

The aim of this essay is to analyze the discursive production of Food, within the Slow food movement, by its members. Through a discourse analysis inspired, theoretically and methodically, by Michel Foucault, this essay examines how the idea of food ? that is ?what should be eaten? ? in opposite to what can be eaten, is constructed within by Slow Food members in the Gothenburg area. The essay analysis how Slow Food?s food discourse is structured and what results this formation has on food within this discourse.

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..
