Uppgiften var att ta emot och avkoda en radiosignal för tidsangivelse, DCF77. Avkodaren implementerades i en FPGA-krets från ALTERA. Utvecklingen genomfördes i Quartus II-miljön med språket VHDL samt en alternativ lösning där mjuk processor användes. Både utvecklingsmiljön och språken var väl lämpade för uppgiften. Ett genomgående problem var dock radiomottagaren ofta levererade för svag signal för att kunna avkodas korrekt.

Digitala ytmodeller (Digital Surface Model ? DSM) används ofta i geodetiskt sammanhang. DSM har länge skapats bland annat med hjälp av fotogrammetri där flygbilder har tagits med traditionella flygningar. Intresset tilltar nu för att framställa DSM med hjälp av obemannade flygfarkoster, så kallade UAS (Unmanned Aircraft System). Den största fördelen med UAS är att det går snabbt och enkelt att få den lilla flygfarkosten upp i luften för att ta flygbilder och framställa DSM kostnadseffektivt.Syftet med detta examensarbete var att undersöka vilken höjdosäkerhet som kan uppnås i DSM som framställts genom fotogrammetri med UAS.

This thesis purpose is to investigate the sociopolitical factors and causes that led to why KB chose not to use the criteria and guidelines for their digitization activities are described in DIGSAM. To do this I focused on three research questions;- What factors (internal / external) led to the decision not to use the criteria guidelines for digitization, which is described in the policy document DIGSAM and what arguments and opinions formed the basis for the decision.- What is the Library's digitization activities, the factors, criteria and guidelines governing activity in the current situation? - Will KB's choice not to use DIGSAM as a whole in their digitization activities affect national library's role as a beacon for the Swedish libraries digital work? In what way and why? In order to answer these questions I interviewed three of KB:s librarians who had extensive knowledge of digitization and DIGSAM. I chose to also use a pilotstudy that was conducted at KB in the of spring 2010. The idea was to use this material as a basis to build on.As a theoretical framework, I chose to use a socio-political theory of Ingrid Mason.

Laser for material processing possesses a number of advantages which mean that it has been and will be an important component for a wide range of industries' future development. Cutting materials processing is the dominant use of laser technology and has revolutionized the manufacturing industry. The aim of this thesis is to describe the principles of metal cutting by laser, how laser cutting is applied in practice and to identify how Swedish companies are using laser cutting. For the theoretical and technical description of laser cutting literature studies are the primary source of information. The empirical basis for the mapping of the Swedish industry for laser cutting is grounded on a survey; this includes Swedish companies that use laser cutting in their production.

This quantitative study explores how employee perceived efficiency within customer service is affected by standardized routines, digital tools, and motivational factors. The study is based on survey data collected from 42 employees across five customer service departments in a larger organization. The theoretical foundation integrates Weber?s bureaucracy theory, the Technology Acceptance Model (TAM), and the Job Characteristics Model (JCM), allowing for a multidimensional analysis to capture the employees' experiences of efficiency. Findings reveal a statistically significant positive relationship between perceived efficiency and both standardized routines and perceived digital tool usefulness and ease of use. Furthermore, the study identifies that skill variety and task significance are positively correlated with experienced meaningfulness, which indicates a potential mediating relationship between these motivational aspects and perceived efficiency.

Since the beginning of the 21st century the Open Access-movement, which advocates free online distribution of scholarly information, has gained momentum. Authors can provide Open Access to their work in two main ways: by depositing a copy of their research output in an e-print archive and by publishing in Open Access journals. During the past few years, universities and other research institutions throughout the world have established institutional repositories to manage, preserve and provide access to the intellectual output of the university/research institution. The purpose of this master?s thesis is to describe the implementation of an institutional repository at the Swedish University College of Borås.

The mainpart of this thesis is about the developing of a new analysis tool to be used in Zenicor Medical Systems AB ECG-system. The primary task of the system is to simplify the ECG survey for patients who suffers from different kinds of arrythmias, for example heart fibrillation. With this system is it possible for the patients to do their ECG survey by them self at home and then send the signal with their telephone or mobilphone to a server. The equipment used to do the survey is not bigger than you can have it in a pocket and this results in a bigger flexibility for the patient. A doctor can connect to the server and analys the ECG-curve and follow up the patients condition..

Detta examensarbete utgår ifrån en artikel i vilken en metod för att skapa holografisk video beskrivs. Syftet med arbetet är att återskapa denna metod. Metoden bygger på projicering av hologram med hjälp av delar från en projektor, en laser och några linser.Först görs en litteraturstudie för att få förståelse över hur metoden fungerar. Här behandlas hur ögat ser djup och vilka olika typer av displayer det finns för att återge tredimensionella holografiska bilder. Vidare beskrivs skillnaden mellan optisk och datorgenererad holografi.

Denna rapport kommer att behandla processen i skapandet av RADA som är en applikation där användare kan dela idéer. RADA är ett uppdrag av Acne Digital som jag har tillägnat 3 månaders praktik. Målet med RADA är att medarbetarna som jobbar på Acne Digital ska på en snabbt och interaktivt sätt kunna dela idéer och bilder. Rapporten beskriver hur arbetet gick till från koncept, design och utveckling till en färdig slutprodukt. Jag kommer att undersöka skillnaderna mellan olika tillvägagångssätt när det gäller utveckling och design för webbaserade applikationer och så kallade native applikationer, som släpps på App Store eller Google play.

To be able to plan different treatments, accurate data is required. The collection of data is often expensive and that?s why the aim is to lower the inventory costs without loosing the accuracy of the data. Holmen Skog has in its strive to lower the costs, decided to evaluate two different methods for forest delineation, computer aided forest delineation and digital stereo view. This study?s purpose is to evaluate these two methods in regard to usability for a beginner and how good the delineation gets.

Detecting small signals with a comparator demands that the total voltage offset is lower than the actual signal. The total offset includes the voltage offset in the comparator and the voltage offset that is created by the offset currents that flows thru the load at the comparators input. The goal with this comparator that has been developed has been that it will have a total voltage offset at maximum 500 uV. The comparator does not need to be extremely fast or does not need to operate in a big frequency area. To have all the flexibility that is needed a full custom technique is used.

The purpose of my study is to give a good picture of what social media really is and how companies can make use of it, in their marketing strategy.

This study gives you a snapshot over todays situation in the area of social media marketing.I have interviewed four different persons, who I believe have a great competence and are highly qualified for this kind of study. All of the interviewed persons work with social media marketing at a daily basis.

One of the main tasks of the Swedish Armed Forces over the past few years has been International assignments, which increased the importance of the Lessons Learned process. Methods of simulator training with computers have become more frequent and the technical ability to collect digital data from sensors has been developed as well. This work demonstrates how the experience of Lessons Learned can be communicated with the computer simulator StriSimPC and how modern technology in future support experiences from the Lessons Learned process at the tactical level in the Army.Currently knowledge sharing consists of several processes and strategies in the Swedish Armed Forces. This is done by written reports, oral presentations and different practical exercises.This case study shows the functions of the simulator StriSimPC, methods of training and how it is used today. The study also describes the future opportunities, where digital metadata acquired from the modern combat vehicles could contribute sharing of experience in the Lessons Learned process.The summarized conclusions indicate that StriSimPC can combine the two strategies for personalization and codification of knowledge transfer to reach a higher level of learning.

The diegetic game world places high demands on how it is designed. It is common that game developers wants to create a deeper player immersion and some developers believe to achieve this by integrating HUD elements into the game world. To find out how digital games can rely on the design of the game world, we performed user studies on beginners who have very limited experience of playing digital games. By observing the beginners, we could discern the visual aspects in the diegesis that helps players understand the game rules and objectives because the beginners won`t make their choices based on previous gaming experiences. If players encounter a variety of difficulties to understand the rules of a game, then it will less likely be a successful game.
