Detektion av vätgasläckor med CUSUM-algoritmen
Detektion av gasläckor används i en mängd olika applikationer som till exempel kvalitetskontroll av kylskåp, lokalisering av skador på kablar och lokalisering av bränsleläckor i bränsletankar.Denna rapport undersöker förbättring av detektionsalgoritmen i en existerande vätgasdetektor.CUSUM algoritmen är en enkel men kraftfull metod för att snabbt detektera små ändringar i nivån av en signal. Denna metod är anpassad till det dynamiska beteendet i sensorn som används för att spåra vätgasläckorna och även utvärderad på omfattande mätningar utförda på läckor med kända storlekar. Resultaten visar att användning av den föreslagna detektionsalgoritmen innebär en betydande ökning av detektorns prestanda. Särskilt bra blir resultatet på små läckor..
Redovisningens värderelevans av fritt kassaflöde : för den svenska aktiemarknaden
Problem: Is the free cash flow a value relevant accounting measure in relation to the Swedish stock market?Objective: The aim is that by using an investment strategy to examine whether the free cash flow is an accounting measure that could be perceived as value relevant in relation to the Swedish stock market.Method: The paper is based on a quantitative survey of empirical evidence that has been collected from companies listed on the Large and Mid-Cap lists of the Swedish stock market.Theoretical Frame of reference: value relevance, cash flow, portfolio theory, drive theoryResults: It was concluded that the study results conform to the Finnish survey results. The portfolio shows higher returns than the OMX index..
Hinderdetektering och kartläggning för autonom robot
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.

Studiemotivation en jämförelse mellan gymnasieelevers egen uppfattning om motivationsnivå och Self-Determination Theory : en jämförelse mellan gymnasieelevers egen uppfattning om motivationsnivå och Self-Determination Theory
Studien handlar om svenska gymnasieelevers motivation för att studera matematikämnet. Den teoretiska grunden hämtas ifrån Self-Determination Theory (Deci & Ryan, 1985). Studiens syfte är att undersöka hur väl gymnasieelevers egen uppfattning om sin motivationsnivå kan prediceras genom de fyra ingående motivationsorienteringarna i Self-Determination Theory: (1) external regulation; (2) introjected regulation; (3) identified regulation; och (4) intrinsic motivation. Deltagarna (n = 132), 44 pojkar, 84 flickor och fyra som valde att inte specificera kön, studerar vid två gymnasieskolor i Falu kommun. Deltagarna fick via en webbsida besvara en enkät som mätte variablerna: upplevd motivationsnivå, external regulation, introjected regulation, identified regulation och intrinsic motivation.
Cash-to-cash-styrning : ett spelteoretiskt angreppssätt
Objective: The objective is to examine if long terms of payment are created because of a perceived zero-sum game in the cash-to-cash cycles between companies. The study will also examine if dependence effects the dependent companies Cash-to-Cash-cycle because of long terms of payment. Scientific method: The study uses a qualitative and a quantitative method, where primary data is collected from semi-structured interviews. Additional primary data is collected from an unstructured interview with an expert in the field of which is examined. Additional data has been collected from the studied companies? annual reports.Theoretical references: The primary theory has been Game theory, where the researchers have used this theory to analyze the behaviors of the companies.

Post-Columbine - en kvalitativ studie av sju skolskjutningar
The study has got three aims. The first purpose is to implement the Newman et al.s rampage theory (2004) in a more dominant European context. In this way, the theory?s strengths and weaknesses can be exposed. The second objective is to look at the motive.
Att definiera konst : En kritik av George Dickies institutionella teori
This paper treats George Dickies institutional theory of how to define art. Some alternative theories and their originators are also introduced. According to Dickie something is art because it has been created against a background of an already existing artworld. Dickie has formulated his theory in two different versions, ?the earlier? and ?the later?, which differ somewhat in their design.
