This master thesis has been performed at the department of Machine Design at KTH, The Royal Institute of Technology. The thesis has been a part of a global development project in collaboration with Luleå University of Technology, Lund Faculty of Engineering and Stanford University. Corporate liaison and sponsor has been Immerse Global Inc. The project was also performed on sponsorship from the Product Innovation Engineering Program, PIEp. The thesis is a representation of some of the contributions made by the authors.The lack of clean drinking water is one of the key issues facing the world today.

A patient simulator for testing anaesthesia machines has been developed at Maquet Critical Care AB, to reduce costly and time-consuming experiments on animals. The device simulates human lungs regarding lung dynamics and volume, uptake of anaesthetic agents and the production of carbon dioxide, heat and moisture. Further demands on the simulator are durability and size; the device shall be compact enough to be moveable.The resulting simulator fulfils the requirements and enables better repeatability and ability to test extreme cases than experiments on animals do.Uptake of the anaesthetic agent is achieved in a active carbon filter and controlled by regulating the flow. The flow is created by a regenerative blower and controlled using a proportional valve. The uptake can be set by the user or by a simple uptake model modified to recursively handle changes in the concentration of anaesthetic agent.Carbon dioxide is fed into the system from a tank by a mass flow regulator.

Geodata finns idag tillgängligt via geodataportaler runt om i världen. På dessa geodataportaler beskrivs datamängder och tjänster som kommer från olika myndigheter. Geodatasamverkan har uttryckt intresse för att kunna beskriva realtidsresurser på dessa portaler med hjälp av metadata. Utifrån ett samarbete mellan SMHI och Lantmäteriet har denna studie tagits fram där en dynamisk realtidsresurs från SMHI testas beskrivas med Geodataportalens nuvarande struktur. Befintlig litteratur har undersökts för att presentera en bakgrund.

Mitt uppdrag var att undersöka om det fanns potential att förbättra en befintlig prototyp som Actegra AB hade utvecklat. Prototypen är ett system för att övervaka delar i konstruktioner, t.ex. takstolar, broar med mera. Detta sker genom avläsning av en rad trådlösa givare som sedan skickar data till en gateway som är ansluten till Internet. Gatewayen har i sin tur en websida där användaren enkelt kan läsa av datat via dator eller t.ex.

WesDyne TRC AB is a fully owned subsidiary of the global WestinghouseElectric Corporation. WesDyne is a world leader in non-invasive methods for theinspection of nuclear power plants. One of the inspection platforms used to scanfor defects in and around the welds in the reactor vessel is called the T-crawler.The T-crawler operates under water in a radioactive environment by stepping onthe vessel (reactor tank) inner wall using suction cups. The environment is harshand many traditional positioning sensors are not suitable for implementation. Thisthesis investigates the possibility to use a gyroscope and a pressure sensor tocreate an alternative and independent positioning system.

Svenska Aerogel AB has developed the material Quartzene® which is of the typeprecipitated silica and contains calcium - magnesium silicate ((Ca, Mg) SiO3). Thematerial is used for molecular filtration of contaminated air. Qartzene?, which is inpellet form, is porous and has a high internal surface which is a requirement for themolecular filtration. With the use of various impregnations, filtration can affect thedesired outcome.

This report is a description of a developed educational simulator over rail vehicles and its components. The simulator is a hardware-based prototype over a door system on rail vehi- cles. System specialists and technicians will use the prototype. The Simulator should give the user a technical demonstration on how components work in a door system. The proto- type consists of motor, switch, relay and sensor.

This thesis has been carried out in cooperation with a company which develops mobile sensor platforms. The sensors measure different types of data such as temperature, pressure etc.. They will communicate through the internet with a server that stores data in a database. This system will be controlled and monitored through a web page. The project's aim has been to develop this system and to implement a server, a database, a website and a client application that simulates sensor signals.

This thesis aims to analyse relations between the risk of Francisella in endemic areas and environmental variables. The thesis also discusses relations between occurrences of Tularemia and meteorological factors. The analysis resulted in several significant models that explained the occurrence of Francisella. These models can however only be applied to the year 2004 since there were too few test performed the other years, therefore no comparisons could be made. Another conclusion was that the relative humidity was significally higher in the year 2003, the same year as the occurrences of Tularemia was at its peak. .

This master thesis was carried out at Scania in Södertälje, Sweden. It investigates the possibility of changing a connector interface that is used when there is a need for splicing the wheel speed sensor and thereby determine the consequences.The problems that exist with the current connector interface occur during assembly, as more time is required to complete a connection in a reliable manner. A complete connection requires joining the male and female connector, insert the connection into a protective retainer and then strap a cable tie on each end of the retainer. This process makes it more time consuming and it requires 20-30 seconds to complete the connection. Solving this problem would save time and enable easier assembly, therefore resulting in economical benefits.This thesis was accomplished through discussions with different sections at Scania, studying available documentations, observations during assembly, writing a requirement specification and contacting suppliers.The aforementioned methods resulted in four connector suggestions, the DT and DTMH connector from Deutsch, MCON connector from TE connectivity and MLK connector from Kostal, each of them compliant with the set demands of the surrounding environment.

In this report you can get a complete instruction about how to build your own development system for the PIC-processor. This card will be used for laborations for the students at LITH-ITN. With this card you can send new assembler codes (new instructions) down to the microprocessor via the Serialport on your computer. Then the new instructions for the microprocessor will start to execute. We made a solder paste stencil at Campus Norrköping solder paste stencil laboratory.

Idag är antibiotikaresistens ett allvarligt problem. En tillfällig lösning på problemet är att utnyttja synergieffekter som kan uppstå mellan olika typer av antibiotika. Det innebär att antibiotika skulle kunna ha effekt mot bakterier som har utvecklat resistens.I denna rapport har flera olika metoder, för att mäta bakterietillväxt, utvärderats. Dessa metoder indikerar om antibiotikakombinationerna har en effekt. Däribland har både kommersiella och nyligen publicerade metoder undersökts.

This thesis is a part of the project "Sustainable harvesting and storage of sugar beets, more sugar to practice". The work has included a large part of practical experimental work with weight measurement, graduation and storage planning. The aim of the project is to be able to see whether the cultivars react differently in different storage conditions. The project has included storage under controlled conditions to give as accurate results as possible. To be able to mimic the farmers own preconditions the samples was harvested with a conventional Holmer.This project has two parts, one concerning the nature, time and temperature on storage where a number of different cultivars where investigated during three different recording times, two different temperatures and controlled in a controlled environment.
