Konstruktion av sök/räddningsrobot

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.

Grafisk utvecklingsplattform för signalbehandling - Design och implementation

We have different kinds of signal processing everywhere around us in our everyday life, in our cellphones, when we are listening to music, watching TV etc. This makes signal processing a very interesting and important technical area, where the demand of skilled engineers sets the limit of what is possible.Working with signal processing requires in-depth knowledge in areas such as mathematics, physics, electronics, and other related areas. For this, it has traditionally been demanded by a talented developer to also master the advanced programming languages such as C / C + + and Assembler.This has begun to change; today there are several companies that offer graphical development environments for signal processing, environments where programming skills are not needed anymore, and the focus can be on signal processing instead.The goal with this project is to build a corresponding graphical development environment to reach an understanding of what is required of these systems, and also to grasp what opportunities that are available within graphic programming. Inspiration for the work has partly arise from some of the tools available on the market, and partly from previous theses that have been written about graphic programming.The challenge lies in creating a program that can execute signal diagrams in real time from given signal blocks, and be able to handle feedback loops in an efficient way and to do so at the lowest "cost" in terms of clock cycles as possible. This should also be compared against to code, compile and run a complete signal diagram directly.To increase the usability it should also be possibility to externally manage in real time the parameters of the signal diagram during execution.The interface is a separate program, which is to some extent similar to Matlab Simulink, where a signal diagram is drawn up graphically by connecting wires between different signal blocks.

Användning av CAD-data vid NC-programmering

The degree project is performed at Metso Kamfab. The production is aimed on machines everything from handling of fiber to paper pulp. Metso Fiber and Kamfab are using Pro/Engineer for design and blueprint production. The processing department types the NC-programs in notepad on the basis of the blueprints, the CAD-dates that already is there are not used. The aim with the work is to study if Kamfab can use CAM-system for processing and production of programs for their NC-machines.

Dimensionering av ventilhus med avseende på skärkrafter

The company Somas, Säffle, has assigned Fredrik Kjellin the project of finding out how ?KVTF DN250?, one of their own valves, reacts on cutting forces under production. They wish to know if and then how much it?s possible to minimize the wall thickness of the valve with neither plastic nor to big elastic deformations caused by processing.The most critical processes have been identified as rough lathing. The study has shown that the marginal for a wall thickness of two millimeters, to fall short of the yield stress in the most critical process, is good.

Automatisk testning av WebGL på mobil- och desktopenheter

WebGL is a standard for drawing graphics in a web browser. Currently it isn?t widely understood how consistently WebGL performs across a majority of the de- vices that support it. Determining if an image looks correct to a human observer is an interesting problem. The solution for this is useful when developing WebGL applications, since a developer could make better informed decisions during de- velopment.

Tillvägagångssätt vid långsiktigt digitalt bevarande: en studie av bevarandeplanering

Den långsiktiga bevaringen av digital information innebär nya utmaningar för svenska offentliga arkiv. I arbetet med att utveckla system för att hantera dessa utmaningar utgår svenska offentliga arkiv ifrån en konceptuell rammodell kallad Open Archival Information System (OAIS- modellen). Syftet med denna uppsats är att bidra med en ökad förståelse för hur svenska offentliga arkiv kan hantera de aktiviteter som ryms under bevarandeplanering (Preservation Planning) enligt OAIS-modellen. För att uppnå syftet har existerande forskning på området granskats och kopplats till bevarandeplanering enligt OAIS-modellen. För att kunna utvärdera den existerande forskningen har ny empirisk data samlats in genom kvalitativa intervjuer. Viktiga slutsatser som har varit möjliga att dra i denna undersökning är att en migreringsstrategi är att föredra för svenska offentliga arkiv. Det kan även vara lämpligt för svenska offentliga arkiv att frångå OAIS- modellen och lagra teknisk metadata dels i informationspaketet och dels i en separat referensdatabas.

Hedersrelaterat våld och förtryck : en kvalitativ studie om professionellas erfarenheter av utslussning från skyddat boende

The aim of this study was to understand how social workers deal with honour-related violence, with special focus on the processing from sheltered housing. Our qualitative interviews with social workers that work with this kind of problems show that there are both obstacles and opportunities in the processing from sheltered housing. On the negative side are the loneliness, the shame and the guilt that the girls may experience when they need to leave their families. The social services can both be an obstacles and an opportunity. When the girls need to create a new life in a new city they have a lot of opportunities and in the same time it is hard to get to know new friends when you don´t know the city or have much money.

Exportledd utvecklingsstrategi : en studie av ?Export Processing Zones? i Mexico

I denna uppsats undersöker vi Export Processing Zones (EPZ) roll i ett lands ekonomiska utveckling, exemplifierat med Mexico. Fokus för uppsatsen är centrerat kring de bakåtriktade länkeffekter som förväntas uppstå som en effekt av ett EPZ-program. Fenomenet längs den mexikansk-amerikanska gränsen kan sägas ha flera orsaker, men grundas i tillgången på billig arbetskraft samt närhet till världens enskilt största konsumentmarknad. Uppsatsen visar på ett minskat FDI-inflöde, ökad sysselsättning, begränsad teknologiöverföring samt mest jobbspecifik kunskapsöverföring. Eftersom få lokala eller inhemska underleverantörer kontrakteras av EPZ-företagen minimeras länkbildningen.

Allt som finns kvar : Om personarkiv hos föräldrar som förlorat små barn

The object of this two years master's thesis has been to study a specific genre of personal archives by examiningthe archives of nine parents who have lost one or several infants. Using internet-based methods, (e-mail, Skypeand digital photographs), I have conducted qualitative research using a general interview guide technique. Usingresearch from archival theory as well as other fields, my material has been arranged and analysed according tothemes and recurring thoughts picked up from my informants during the interviews.My main theoretical aid has been that the role of parent who has lost a child is the starting point for the creationof the personal archives. Another important theory is my definition of the term ?document? as not dependent onmedium and format, but on usage: if an object has been used as a part of an archive, it is a document.

Digitala signaturer ? ett alternativ för långsiktigt digitalt bevarande?

I denna studie behandlas området långsiktigt digitalt bevarande, med fokus på digitala signaturers lämplighet för autenticering av digitala handlingar. Den teori som beskrivs tar upp vad en digital signatur är, vilka problem dessa har på lång sikt samt konceptet Trusted Archival Services som ett koncept för arkivering av digitala handlingar. Det empiriska materialet har samlats in genom intervjuer med tre valda respondenter. Dessa respondenter har valts utifrån deras praktiska erfarenhet inom detta område. De slutsatser som har kunnat dras av studien är att digitala signaturer inte är en lämplig teknik för att säkerställa autenticiteten i digitala handlingar på lång sikt.

Det sinnliga upplevandet av landskapet : en teoretisk undersökning av positiva emotioners roll vid utomhusrekreation

The purpose with the paper is to theoretically investigate how sensory experience and positive affect in contact with outdoor environment can promote health by 1) develop a model of the sensory and emotional processes based on multiple code theory (Bucci, 1997) and 2) examine if this model can increase understanding of the processes that takes place in outdoor recreation, the way this is described in environmental psychology research and theory. The paper starts by introducing research and perspectives concerning outdoor recreation. Different theories of nature?s health promoting effects are described. These include the restoration theories of Roger Ulrich and Steven and Rachel Kaplan, theories more concerned with outdoor activities and a theory combining these two perspectives called instorative theory. After this sensory and emotional information processing is examined through the works of Wilma Bucci and Jean Ayres. Antionio Damasio?s theories of emotion and Daniel Stern?s concept of vitalityaffects are than introduced to extend this reasoning.

Bevarande av webbplatser : En kartläggning bland statliga myndigheter i Sverige

The purpose of this thesis was to investigate if Swedish agencies preserve their websites according to the Swedish archival legislations and guidelines. As a theory the OAIS Reference Model (Open Archival Information System, developed by US Consultative Committee for Space Data Systems, CCSDS) has been used as a model to show how important it is to develop strategies for public digital information which has to be preserved for long term. The ingest function in the OAIS Reference Model demands that files are prepared for long term preservation and requires that the digital information fulfils established technical requirements.In the study the Swedish National Archive and their advices about preserving websites to archivists on the Swedish agencies are being studied. To control if the agencies meet the requirements for their management and preservation of their websites a survey was sent out to investigate if Swedish agencies preserve their websites. According to the survey result, 84 of 113 agencies preserve their websites in some way. If the technical requirements really was met could not be verified in this thesis, the results was relied on the responses from the authorities.

?Jag undrar varför farbrorn inte hade ett koppel på hunden?? ? En interventionsstudie med syfte att främja elevers läsförståelse och läsintresse ?Jag undrar varför farbrorn inte hade ett koppel på hunden?? : - En interventionsstudie med syfte att främja e

The aim of this study was to investigate the result of an effort to support reading development and the reading motivation. My approach was an intervention study during four weeks, where intensive reading in a group of three pupils in grade one took place. Individual conversations and group conversations were central methods in combination with different ways of processing the texts. Interviews were conducted with the class teacher and the participating children to see the difference in reading and motivation before and after the project. The result shows that an intensive period with reading fiction books with subsequent conversations and different processing of the text is a useful developing method for decoding, reading comprehension and reading motivation.
