ABSTRACTThe aim of this study is to analyse if the UN today constructs the water issue as a security issue and to argue about in which way the organization in that case does so alternatively why it can be said that the UN doesn?t construct the water issue as a security issue.In order to reach this purpose the following questions will be answered:?Does the UN construct the water issue as a security issue today?-If yes, in which way?-If no, why can it be said that the organisation doesn?t?The methods used are qualitative literature studies of policy documents on water from the UN. The focus is to analyze the ideas about water and to apply my theory on the concept of security, which is Barry Buzan?s framework on security, to these ideas.The main results showed that the UN strongly constructs the water issue as an environmental security issue for environments and species and in relatively strong terms also constructs it as an environmental security issue for civilisations. In rare cases the organisation constructs it as a societal security issue, but the UN doesn?t construct the water issue as a military, political or economic security issue..

DARC är ett sätt att sända digital information via FM-rundradionätet. Moduleringsmetoden för DARC är GMSK. Målsättningen var att jämföra kostnad/komplexitet och strömförbrukning för olika sätt att demodulera GMSK. Tre icke-koherenta demodulatorer och en koherent demodulator har jämförts. Man vill veta hur stor resursanvändningen var för olika FPGAer.

This study is based on an earlier interdisciplinary study made by Redbo et al., (2000), Extensive cattle production systems ? out wintering, which lasted over two winters, 97/98 and 98/99, with two groups of heifers indoors and two groups of heifers outdoors raised in different environments, indoors or outdoors during their second winter. Both indoor and outdoor heifer groups were fed grass silage ad libitum throughout the experimental period that lasted from October until May. The objective of this study was to evaluate the long term effects of being raised in these two environments. This study includes data collected during the period lasting from the start of the experiment of Redbo et al., (2000) until the heifers had calved a second time and the results mainly deal with the performance of the animals after the experiment during their first two calvings and their first lactation.

Embedded Systems Lab at Umeå University is currently part of a research project with the purpose to examine the behavior of dairy cows inside a barn. Each cow needs to be tracked with a precision of 50 cm, and since GPS-technique has poor functionality at indoor environments, an indoor positioning system needs to be developed.Embedded Systems Lab has already developed an indoor positioning system using IR-light and radio, but since this system demands extensive infrastructure and is rather expensive, an alternate positioning system using ultrasonic pulses and radio is being examined.In this report the range, beam angle and current consumption of ultrasonic transmitters- and receivers are investigated. Three different driver stages for the transmitter is tested, and two amplifier solutions for the receiver. The report also describes how the length of the transmitted ultrasonic pulse affects the received signal, accessibility of a ?shadowed? signal, and the effect of different sound frequency..

This Master?s Thesis is an evaluation of the software Xilinx System Generator (XSG) and blockset for Matlab. XSG is a module to simulink developed by Xilinx in order to generate VHDL code directly from functions implemented in Matlab. The evaluation was made at Saab Avionics AB in Järfälla, north of Stockholm. In order to investigate the performance of this new module XSG to simulink, a model of a frequency estimator often used in digital radar receivers were implemented in Matlab using XSG.

The purpose of this study is to highlight some aspects of the increased usage of tablets in preschool environments by answering the questions: what does the tablet become in the preschool environment, how much freedom does the children have over its usage.To answer these questions a series of observations were made at two different preschools. The observations were then complemented by interviews with teachers at the same preschools.This qualitative study focuses on some of the didactic questions regarding the tablets, based on a theoretical framework that is within the design-oriented perspective; which addresses the children's? autonomy, the institutional framework and affordance.Our conclusion is that the tablet?s introduction in the preschool has helped the teachers in numerous parts of their documentation, but we can also see that the children's opportunities to make choices regarding the tablet are more limited than with any other resource on the preschool. In our results we also see that when the children get access to the tablet they receive a learning experience, which among other things, strengthens their language skills and their social interaction with each other..

Stress is commonly found in society today. This paper aims to examine how work performance, cooperation and team spirit are maintained in demanding work environments. By studying two departments in a public hospital that practises addiction care, our findings suggest the following: If the experienced stress is mainly connected to challenge stressors, it has a positive effect on work performance. By organising work through mechanistic and organic structure, the handling of qualitative and quantitative stress is facilitated. As a consequence, first and foremost cooperation can be maintained, but also work performance and team spirit.

The aim and goal of this work has been to design and implement a voltage reference network for a 12-bit PSAADC, Parallell Successive Analog to Digital Converter. A chip containing the design has been sent away for fabrication. Because of the long processing time, no measurement data are presented. The main specifications for the voltage reference generator is to generate stable reference voltages with low noise and a good PSRR. Efforts has also been made to minimize the power consumption..

Abstract CORDIC (Coordinate Rotation Digital Computer) is an iterative algorithm for the calculation of a two-dimensional vector in circular, linear or hyperbolic coordinate systems. This paper presents a survey of known CORDIC algorithms and architectures for the rotation and vectoring mode in the circular cordinate system. In addition an implementation of the differential CORDIC algorithm in VHDL has been done. The implementation is designed to keep the fast timing and throughput characteristic known for on-line redundant arithmetic..

This report discusses a method to detect divers in harbour environments usingpassive acoustic detection. The goal was to achieve as high detection as possiblewithout having too high false alarm rate. A short execution time was also desirable.By using the characteristic of an inhalation a band-pass filter was applied to the signalto improve the signal to noise ratio. After the filtering an energy estimation of thesignal was made. This energy estimation was later used in a frequency analysis, whichcould tell us if there were enough energy in the frequencies that correspond to adivers breathing frequency.

Introduktion: Skolios som drabbar barn och ungdomar ger en krökning av ryggraden i sidled. Upprepade undersökningar med joniserad strålning av främst flickor i puberteten innebär risk för bröstcancer. Genom att på olika sätt optimera undersöknings metoderna och använda skydd till patienter kan biverkningarna minskas. Syfte: Syftet med studien var att genom en systematisk litteraturöversikt sammanställa vilka metoder och röntgenparametrar som kan användas för dosreducering i samband med radiologisk skoliosundersökning av barn och ungdomar. Metod: Studien utfördes som en allmän litteraturöversikt.

Tidigare forskning har visat att systematisk självrapportering är en fördelaktig metod för att följa enpersons psykiska mående över tid, och att en digital mätmetod i sin tur skulle innebära många praktiskafördelar jämfört med en analog. Detta är en experimentell randomiserad, kontrollerad studie som medutgångspunkt i personcentrerad vård och spelifiering undersöker 35 personers användarfrekvens ochattityder efter en tvåveckorsperiod där hälften har fått prova att självskatta sitt psykiska mående via enmobilapplikation, och hälften fått göra detsamma via ett analogt stämningsformulär. Resultatet visar enhögre användarfrekvens bland deltagarna i mobilapplikationsgruppen, samt ett uttalat intresse hosbägge grupper för digitala metoder för självskattning av psykiskt mående. Bägge metoderna ansesstärka personcentrerad omvårdnad. The aim of this study is to explore user frequency and attitudes for persons using a mobile applicationfor assessing mental health compared to persons using an analogue assessment method.

This rapport aims to examine the difficulties in presenting a complex game in a way that will invite new players by making the game more accessible.

Our solution to this issue includes RFID-tags and readers together with four buttons, as input devices. This simple input device, placed in a gun-type control unit, aims to provide an intuitive interaction..

På uppdrag av Tidningsutgivarna har en studie utförts angående olika möjligheter att införa tryck av variabeldata med tryckmetoden inkjet i svensk dagspress. Målet var att undersöka tekniska möjligheter och begränsningar samt att utreda om det fanns något intresse på marknaden som skulle kunna ge någon avkastning. Studien utfördes med hjälp av noggranna källstudier och ett fortlöpande samarbete med olika företag med intresse för dagspress. Rapporten beskriver också företag som arbetar med den här typen av innovationer idag och diverse tidigare projekt med variabeltryckta tidningar. Nya teknologier som eventuellt kan vara av intresse för framtida utveckling har också beskrivits och hur tidningens framtid kommer att se ut ur ett kortare och ett längre perspektiv.Studien visar att inkjetpressar inte klarar av den hastighet som de moderna tidningspressarna håller idag.
