This report studies the possibility of using some sort of radio sender and transmitter in order to position skis lost in powder snow. It is concluded that a RF-solution on the 433 MHz frequency should be the most efficient. Different forms of directional antennas are examined and studies show that in theory the best suited is the so called “Yagi-Uda antenna”. A solution based on using a Receive Signal Strength Indicator value together with the above mentioned directional antenna is developed. To control these different components microprocessors from Atmel is used. These are programmed in C and compiled with Atmel’s own compiler AVR Studio. Despite all efforts it is proven that the prototype does not perform in an adequate way. An alternative solution based on “byte-loss-rate” is then developed and the results are slightly improved. Nevertheless, the directional properties of the antenna are still too poor why other alternatives are discussed. No fully functioning prototype is achieved but good grounds for further development of the prototype into something that fulfills the specifications are produced.

Control applications are used in almost all scientific domains and are subject to timing constraints. Moreover, different applications can run on the same platform which leads to even more complex timing behaviors. However, some of the timing issues are not always considered in the implementation of such applications, and this can make the system fail. In this thesis, the timing issues are considered, i.e., the problem of non-constant delay in the control of an inverted pendulum with a real-time kernel running on an ATmega328p micro-controller. The study shows that control performance is affected by this problem. In addition, the thesis, reports the adaptation of an existing real-time kernel based on an EDF (Earliest Deadline First) scheduling policy, to the architecture of the ATmega328p. Moreover, the new approach of a server-based kernel is implemented in this thesis, still on the same Atmel micro-controller.

Thesis focuses on interpretation of nested petri nets described in PNML language on Atmel processors. It introduces this limited - from memory capacity and perfomance point of views - targeted architecture, since it greatly affected both design and implementation. The interpreter is thouroughly described from all aspects of its design. One of most important concerns in the whole process was the ability to test and verify achieved state of functionality quickly and possibly without Atmel processor. That’s why the implentation took place on a squeak platform, that allowed to translate whole interpreter for targeted platform. Motivation behind this and overall process of translation is also a subject of this work.

This study examined attitudes toward multiple role planning (ATMRP) amongst engineering students in South Africa (N = 146). ATMRP is an individual’s attitude or orientation toward planning for future involvement with work and family. Individuals with a more realistic attitude toward multiple role involvement are more likely to successfully manage a multiple role lifestyle. Exploratory factor analysis showed the multidimensionality of the ATMRP scale. The five dimensions were knowledge/certainty, commitment, independence, involvement and flexibility/compromise. The study examined the influence of cultural orientation i.e. gender role ideology, allocentrism and ideocentrism on their attitude toward planning for future work and family roles.

Os óleos vegetais estão cada vez mais em evidência já que esses materiais renováveis e versáteis podem substituir derivados de petróleo para a síntese de novos polímeros. Como o óleo de linhaça é constituído principalmente de ácido a-linolênico, um ácido carboxilíco contendo 18 carbonos e três duplas ligações cis em sua cadeia, ele é considerado uma alternativa interessante para a síntese de poliésteres funcionalizados via metátese de trieno acíclico (ATMET). Nanopartículas poliméricas ori-undas de monômeros com baixa solubilidade em água, como o óleo de linhaça, podem ser obtidas por polimerização em miniemulsão, onde cada nanogota de monômero age como um nanoreator. Entretanto, é um desafio realizar as reações de metátese em miniemulsão devido a dois efeitos importantes e negativos no catalisador, que são a decomposição parcial do metilideno em água e a possível diminuição da atividade cata-lítica dependendo do tipo de surfactante utilizado na miniemulsão. No presente trabalho, uma série de polimerizações do óleo de linhaça via ATMET foram conduzidas, utilizando as técnicas de massa e miniemul-são, com o objetivo de estudar a atividade de diferentes tipos de catali-sadores baseados em rutênio (Grubbs 1ª e 2ª geração, Hoveyda-Grubbs 2ª geração e Umicore M2) em ambos os sistemas. Três diferentes surfac-tantes foram utilizados (CTAB, Tween 80 e Lutensol AT80) para as miniemulsões. Para obter massas molares mais altas foram aplicadas condições como vácuo e purga com nitrogênio. Os processos estudados resultaram em polímeros com massa molar média numérica (Mn) de até 6,3 kDa em massa e 5,8 kDa em miniemulsão, dependendo do catalisa-dor e do surfactante utilizados. A massa molar mais alta na reação em massa usando o catalisador Grubbs 1ª geração pode ser atribuída à par-cial decomposição de catalisadores rutênio-benzilidenos em água. Po-rém, os resultados de massas molares em miniemulsão são comparáveis aos em massa quando o catalisador Umicore M2 e o surfactante Luten-sol AT80 foram utilizados, indicando que esse catalisador é mais robus-to para sistemas aquosos e o surfactante não-iônico empregado não afeta a cinética das reações via ATMET.

Abstract : Plant oils are earning growing attention since these renewable and versatile materials could potentially replace petroleum derivatives materials for the synthesis of new polymers. As linseed oil mainly consists of a-linolenic acid, a carboxylic acid with an 18-carbon chain and three cis double bonds, could also be an interesting alternative for the synthesis of branched and functionalized polyesters via acyclic triene metathesis (ATMET). Polymer nanoparticles of monomers with very low solubility in water, such as linseed oil, can be obtained by miniemulsion polymerization wherein monomer nanodroplets act as a nanoreactors. However, it is a challenge to perform metathesis reactions in this system due to two important and negative effects of metathesis catalysts, specifically the partial ruthenium methylidene decomposition in water and the possible decrease of catalyst activity in miniemulsion depending on the type of the surfactant used. In the present work, a set of ATMET polymerizations reactions of linseed oil was performed in bulk and miniemulsion to evaluate the activity of different types of ruthenium-based catalysts (Grubbs 1st and 2nd generations, Hoveyda-Grubbs 2nd generation and Umicore M2) in both systems. Three different surfactants (Cetyltrimethylammonium bromide, Tween 80 and Lutensol AT80) were evaluated in the miniemulsion reactions. In order to achieve higher molecular weights, vacuum or nitrogen purging were used. The studied processes produced polymers with number average molecular weight (Mn) up to 6.3 kDa in bulk and 5.8 kDa in miniemulsion, depending on the catalyst and the surfactant employed. Higher molecular weight observed in the reaction in bulk using Grubbs 1st generation catalyst may be attributed to partial Ru-benzylidene catalysts decomposition in water. Moreover, Mn results in miniemulsion polymerizations were found comparable to bulk reactions when Umicore M2 and Hoveyda-Grubbs 2nd generation catalysts and nonionic surfactants were used, indicating that these catalysts are more robust in the presence of water and that the non-ionic surfactants do not affect the kinetics of ATMET reactions.

AVR32 is a new processor architecture made by Atmel Norway, and in this thesis it has been used to make a control system platform. The hardware used in this platform is the STK1000, an AVR32 development board and an I/O-card. The I/O-card were developed as a part of the thesis. Software for the platform consists of I/O-card firmware, Linux device driver for the I/O-card and user mode drivers. The platform supports usage of Matlab Real-Time Workshop as a rapid prototyping tool, that generates code from graphical visualization of mathematical models. S-functions were created so Matlab Real-Time Workshop can control the I/O-card. The control system platform is documented in an user manual. This manual describes how to install development tools for the platform on a Linux or Windows computer, and how to use the it.

I detta projekt undersöker vi om man kan bygga en maskinaktivitetssensor med

hjälp av en enkretsdator som genom en accelerometer mäter en maskins

vibrationer. Sensorn skall generera en statussignal. Accelerometern ger en

mätbar signal baserad på maskinens vibrationer. Enkretsdatorn används för att

sampla, transformera och analysera signalen och generera statusinformation.

Med LabView kan vi spara, studera och analysera olika signaler och olika

transformer. Vi studerar maskinvibrationer i LabView och beslutar att 5 kHz

sampling räcker för att fånga intressanta vibrationer. Vi jämför transformers

egenskaper och beräkningskrav och väljer Fouriertransform som analysmetod.

Vi beräknar att en Atmel ARM SAM7S256 kan utföra uppgiften och

implementerar interruptbaserad signalsampling, frekvensanalys och en

beslutsrutin som resulterar i en utsignal med statusinformation.

In this project we examine the possibility to create a machine activity sensor by

a one-chip computer that measures a machines vibrations through an

accelerometer. The sensor shall generate a status signal. The accelerometer is

used to give a measurable signal of a machines vibrations. The one-chip

computer is used to sampel, transform and analyze this signal and generate a

status signal. With LabView we can save, study and analyze different signals

and their different transforms. By studying machine vibrations in LabView we

decide that sampling at 5 kHz is sufficient. By comparing different

transformations in regards to performance and calculation needs we choose

Fast Fourier Transform as analyzing tool. We calculate that a ARM

SAM7S256 can manage the task and implement an interrupt based sampling,

frequency analysis and decision making routine which results in a status signal.

Today, more and more embedded hardware devices are reaching the market and consumers with a demand for smaller and better devices than yesterday. Increasing the performance of a device decreases the operating time since more power is consumed, still, decreasing the size of the device also decreases operating time as the battery size decreases.To allow the performance to increase and the size of the device to decrease, the designer must nd techniques allowing the hardware to consume less power during normal usage of a device than during the peak usage.In this thesis an implementation of an ARM based microprocessor system is presented and used for measuring and evaluation of the power consumption possibilities of the system.

This report describes the development of a sample loader for my diploma work at Q-linea AB in Uppsala. The sample loader will replace the process of loading fluid samples into Q-linea’s instrument for biomolecule analysis. The earlier process was done by hand and was a time consuming and inefficient task. The work was initiated with a design phase where an overview of the system was created. The sample loader will be receiving text commands from a PC that coordinates all the subsystems like pumps and lasers on the analysis instrument. The commands will be translated by a microcontroller into the correct movement of the samples needed to load them. Most of the work was put down into developing the software responsible for handling communications and actuation of a couple of stepper motors. Lastly a circuit board was designed and manufactured, ready to be mounted into the existing instrument. The result was a working prototype which now is used in the daily work at Q-linea. It is subject for further development and in the future it will be shipped as a part of the finished biomolecular analysis instrument from Q-linea.

Il sistema di acquisizione dati del nuovo layer IBL di ATLAS conta attualmente 15 schede ROD attive sull’esperimento. In ognuna di queste schede sono presenti due catene JTAG per la programmazione e il test. La prima catena è facilmente accessibile da remoto tramite uno standard VME o Ethernet, mentre la seconda è accessibile solo tramite un programmatore JTAG. Accedere alla catena secondaria di tutte 15 le ROD è in primo luogo sconveniente poiché sarebbero necessari 15 programmatori diversi; in secondo luogo potrebbe risultare difficoltoso doverli gestire tutti da un unico computer. Nasce così l’esigenza di sviluppare un’elettronica aggiuntiva con funzione di controllo che riesca, tramite un unico programmatore, a distribuire un segnale JTAG in ingresso a 15 uscite selezionabili in maniera esclusiva. In questa tesi vengono illustrati i vari passaggi che hanno portato alla realizzazione del progetto ponendo attenzione alla scelta, al funzionamento e all’eventuale programmazione dei componenti elettronici che lo costituiscono. Per ogni parte è stato realizzato un ambiente hardware di prototipazione che ne ha garantito il test delle funzionalità. La scheda, basata su un microcontrollore ATmega 328-P, è attualmente in fase di completamento nel laboratorio di progettazione elettronica dell’INFN di Bologna. Il prototipo studiato e realizzato tramite il lavoro di questa tesi verrà anche utilizzato in ambiente CERN una volta che ne sarà convalidata l’affidabilità e potrà anche essere facilmente adattato a tutti gli esperimenti che usano un protocollo JTAG per la programmazione di dispositivi remoti.

The thesis deals with the design and implementation of smart house lighting. In the living parts of the house, the light intensity is maintained at a constant level which is set by the user. The intensity of lighting can be set manually for each room from a central module with a user interface. It can also be changed by any remote control directly in the room in which the user is currently located. When the remote control is used, the information about the change of light intensity is transmitted to the central module. For communication between the central module and the luminaires, the existing power lines are used.
