This report describes the development and implementation of a system for transmitting digital information at high speeds from a miniaturized submersible developed by the Ångström Space Technology Centre at Uppsala University. For instance, the vehicle shall transmit image data ? even stream live video - through an optical fibre to a monitor in a ground station. Hence, the system shall be used both to convert the image data to make it transmittable, and to recreate it at the receiver.The work includes a pre-study of the programming language and the technology used. A concept for the solution is presented together with main components later broken down into internal functions.

The task was to design and manufacture a submersible displacement pump working with the wobble plate principle. The main task for the Wobble plate pump is to be used as a sewage pump for smaller households or dewatering pump in environments where small flows and high pressures are acquired. For these purposes ITT Flygt sell a screw pump, PC-Grinder 3068. The hydraulic part of the PC-Grinder is manufactured by a subcontractor. Therefore ITT Flygt wants to evaluate an alternative to their screwpump PC-Grinder, which can be entirely manufactured by them self.

Internet and information technology today has a rather obvious role in the activities of companies and organizations. All cash transactions within and between companies is digitized, communication within the company is done via e-mail, sales and marketing is done largely with marketing and ads on the Internet. This has resulted in economic benefits for companies and organizations, and facilitated the work for them. However, this has also led to new threats have emerged. Companies and organizations is well aware that there are numerous threats that comes with using the Internet and Information Technologies but exactly what those threats are for a mid-sized company in Sweden is not clarified anywhere.

This bachelor thesis is about an ultrasonic sensor, implemented in a bubble chamber in Artis. The sensor consists of the piezoelectric sensor and an electronic control circuit. The control circuit consists of a programmable microprocessor, PIC18F2420 and a circuit, which sends the excitation signal to the piezoelectric sensor, and later receives the echo. This bachelor thesis consists also of a theoretical study, which examines different techniques of liquid level sensing in a chamber. The study discusses which factors are important in liquid level sensing and examine accepted methods.

Detta arbete har två olika delar som behandlats på olika sätt. Inledningsvis har dagssituationen för teknikämnet i grundskolan kartlagts. Bland resultaten återfinns ett samband mellan behöriga tekniklärare samt de lärare som själva valt att undervisa i teknik, och intresset för ämnet teknik. De behöriga tekniklärarna återfinner vi framförallt i de större städerna. I den största gruppen lärare som undervisar i teknik, No lärarna, har endast tio procent valt att undervisa i ämnet själv.

 The aim of this essay is to examine if the Swedish Major labels are moving towards making their catalogue available on different platforms rather than their traditional distribution of music. The new technology has really stirred things up for the major labels and file-sharing has been a problem for a long time. The labels have a history of fighting new formats instead of embracing them and listen to what their consumers actually want. We have found that the majors now are in the leading edge of music distribution due to technology and that is a first. We have focused this essay on if the consumption of music has changed the distribution of it or the other way around and found that people have changed their ways of consuming music over the years and the labels have always been forced to adapt.

The three dystopian novels Brave New World by Aldous Huxley, Kallocain by Karin Boye and Nineteen Eighty-Four by George Orwell have been highly discussed amongst literary critics and scholars. Although these works are well-known, some themes have had very little or no recognition. Biological reproduction is a recurring subject in dystopian literature. Although it is not the main theme in the novels, it is a very important part in dystopian culture and dystopian society. By focusing on reproduction and the structure of gender roles in these three dystopias, I hope to bring to light something that's been in the shadows for a long time i.e.

Facilitated by the breakthrough of the internet, new ways of organizing internet-based projects that harness the power of the crowds are becoming increasingly common. Today there are ways of using the crowd as paid labour, as funders of your new project ventures and even for helping scientists doing science. Staying true to its traditional principles of objectivity and trustworthiness while asking the crowd to contribute, crowd generated ?Citizen Science? does not provide even the slightest amount of pay in exchange for the time and effort put in by their contributors. Surely there can not be many people willing to do such a thing voluntarily? Actually, practice is showing the exact opposite with contributions counted in their millions among the more popular Citizen Science projects.

Det FInns många typer av identikationsmedel och i denna rapport redovisas uppbyggnaden av en prototyp som använder ansiktsigenkänning för identifiering vid en dörr. Prototypen är ett resultat av ett examensarbete på företaqet Wawo Technology AB och författarens roll i projektet var som projektledare. Projektledarens fokus låg på kommunikation med teammedlemmarna, på att driva projektet framåt samt på att användartesta systemets alla delar. Resultatet av projektet blev en prototyp som i dagsläget är monterad på ett kontor och används av personalen. Registreringen till systemet sköts viaen hemsida av en administratör.

Med ordet 'omfattande' försöker vi indikera att projektet har inkluderat de flesta aspekter som arbetas med i modern 3D-animerad film. Vi har grävt ner oss i begrepp så som modellering, texturering, UVW, benriggning, skinning & morphing varav alla har spelat in en viktig roll vårat animationsarbete..

Safe operation of a large synchronous power system as Nordel is not an easy task.There are several aspects to take into consideration. This thesis focuses on the problems due to voltage collapses in a transmission system.The ability to foresee an upcoming collapse is vital to maintain stable operation of the grid. The grid operator at Svenska Kraftnät (SvK) uses the computer program SPICA to predict the maximum transfer limit at specified transfer sections. SPICA uses actual states from the grid to predict the transfer limitation, and a quarter later a renewed estimate is produced and so on. This means that the operator can se his transfer limits vary every fifteen minutes.Our task in this project is to validate the accuracy of the limitations obtained by SPICA.

Abstrakt I den här uppsatsen undersöks hur ett narrativ kan drivas inom digitala spel enbart med hjälp av spelmiljön. Syftet är att få förståelse för vad miljöberättande behärskar som en självständig form av berättande och vad författarna kan göra för att uppnå detta mål. För att undersöka problemområdet genomfördes en spelproduktion där metoder framtagna under undersökningens gång applicerades. Produktionen testades av utomstående studenter i medieteknik och resultaten sammanställdes med reflektioner kring vad som uppnåtts och de metoder som applicerats. Undersökningen beskriver arbetsprocessen och metoder och visar hur dessa kan driva ett narrativ med en spelmiljö. Abstract In this thesis examines how to drive a narrative in digital games using only the game environment.

Denna uppsats beskriver Internet i Kina i allmänhet, från dess politiska bakgrundsmotiv och inledande grunder till dess nuvarande tillstånd av dynamisk ekonomisk infrastruktur och medel för folkligt politiskt inflytande. Tonvikten läggs vid för Kina unika aspekter, såsom partiinflytande över informationsutbytet, folkliga attityder till fildelning i ett samhälle som bara nyligen erkänt privat ägande samt effekter av kulturkrockar på nätet mellan västlig och kinesisk civilisation. Det argumenteras för att Kina i en framtid kommer att ha ett stort inflytande över cybermarknader och i beslutsfattande om Internets framtida utveckling, genom tekniska, ekonomiska och politiska medel. Slutligen resoneras att Internet i Kina har förändrat och kommer att förändra folkets mentalitet, så att det anammar västerländska tankemönster i liknande utsträckning som i angränsande länder, vilket banar väg för politisk pluralism..
