The objective of the thesis is primarily to conform and encode a digital signal to be controlled by software. The idea is to transport today?s tracesignal through the IP-network instead of cable-net. In this report I will suggest a possible solution to get a fully passed result with no peculiar time delay. I will also suggest some ideas for a future work with the new tracesystem..

Syftet med uppsatsen var att ta reda på hur man som pedagog kan arbeta med digital portfolio i förskola samt hur digital portfolio kan fungera som ett underlag till reflektion över pedagogens verksamhet samt som ett verktyg till att förändra den. I min undersökning har jag använt mig av en kvalitativ metod i form av intervjuer med pedagoger i förskolan som arbetar med digital portfolio. Min studie visar att pedagogerna anser att digital portfolio är ett arbetssätt som synliggör barns lärande för pedagogerna, barnen själva samt för föräldrarna. Studien visar även att digital portfolio används till att förstå och förändra den egna verksamheten men att pedagogerna inte på ett medvetet sätt använder digital portfolio till det syftet. I min diskussion för jag ett resonemang om resultatet samt om möjligheterna med digital portfolio..

For systems with multicore processors contention for shared resources is a problem that occurs when several memory-intensive processes are executed in parallel within the same memory domain. This contention has a direct influence on the performance of the system and is a complex problem that has been recognized for a long time. An attractive and actively studied way to minimize this problem is by using a process scheduler adapted to allocate processor cores in a way such that contention for shared resources is minimized.With the introduction of multicore NUMA-systems (Non-Uniform Memory Access) the situation has become even more complex. In these systems the access time for processor cores to different memory domains vary depending on factors such as distance and load. Thus, the process scheduler also has to consider where the memory of each process is placed to minimize the distance and balance the load on each memory domain.This report presents a user-level process scheduler for a NUMA-system based on the multicore processor Tilera TILEPro64.

I dagens visuella effekter är digital compositing en av de viktigaste processerna. Från att uteslutande ha utförts i 2D har digital compositing dock kommit att innebära en alltmer tredimensionell process. Det här arbetet reder ut begreppet 3D-compositing och sammanställer vilka 3D-compositingtekniker som är vanligt förekommande. Ett urval av dessa tekniker tillämpas sedan i en egen effektsekvens. Slutsatsen blir att det är kombinationen av 3D-funkionalitet och 2D-compositing i samma program som är styrkan med digital compositing i 3D-miljö..

I denna studie har skolledares åsikter och insikter kring digital kompetens stått i centrum. Syftet har varit att genom intervjuer belysa vad begreppet digital kompetens innebär för skolledare och hur rektorer ser på sin och lärares yrkesroll kopplat till digital kompetens. Utgångspunkt i denna studie har varit rektorernas egna uppfattningar kring begreppet digital kompetens.  Studien är en fallstudier med intervjuer, och ett abduktivt synsätt har applicerats då den söker mönster i de åsikter och tankegångar som de utvalda skolledarna angivit i sina svar..

During the development of microwave based sensors such as radar target seekers, input signals are needed to verify the performance of the system. Therefore, a channel board has been developed by previous thesis projects at Saab Bofors Dynamics. It uses a technique called Digital Radio Frequency Memory (DRFM). The purpose of this board is to sample and digitally store radio frequency signals in order to reconstruct them after a certain delay.The aim of this thesis project was to use the channel board named above to construct a portable instrument for generation of stimuli signals. This assignment has been divided into two tasks: firstly, to construct and put together the hardware components and secondly, to implement a graphical user interface for the instrument.

This essay is a product of our examination work on candidate level in Interaction Design. The aim in this project was to design a digital wallet integrated into a cellular phone and make it as an electronic payment tool. In our project the goal has been to create a digital wallet not just for payment, but also develop it into a complete digital wallet, replacing visa, membership card, student cards, id card and receipt. Our ambition is to take care of current qualities of today's wallet and improve where it is possible so that can be replaceable with the digital wallet..

The purpose of this project was to produce signal relay stations that could receive information via 2.4 GHz radio and relay the information to a designated target station. If a relay station was located outside of signal range for the target station it was supposed to utilize other relay stations to transfer the information to the target station, so called multi-hop.The would-be application of the relay stations was orienteering. When an orienteer punches a checkpoint the signal stations would relay information of who punched the control, when it was punched and the checkpoint that was punched to the speaker tower in the goal area.The work resulted in prototypes which fulfilled the statement of purpose and was tested at an orienteering competition with satisfactory results. The performance of the prototypes was tested and found adequate for the would-be application..

This thesis studies the negative impact that control signal saturation may have on a controlled system. Different methods that are used to compensate for this problem are also studied and evaluated. Both sensitivity to disturbances and the effect the method has on the systems'ability to follow a reference signal will be examined. Stability will be discussed, but no conclusions whether the systems are stabilized or not can be drawn. Control signal saturation will lead to a slower behavior in general.

Projektet i denna rapport har fokuserat på hur man kan förbättra den visuella och taktila upplevelsen av digitala slagverk. Målet var att utveckla en digital version av moderna percussionisters shakers, som tilltalar användarna inte bara med sina funktioner och digitala möjligheter utan även som ett musikinstrument.Processen och utveckling av instrumentimagen för digital percussion kan appliceras på alla digitala instrument, men resultatet av detta projekt illustreras genom ett koncept på en digital shaker..

This report tested the possibility of using induction as a mean for transferring data and power so that it can be implemented as a communication medium between a terminal and measuring head mounted in a measuring frame. This would eliminate the need for the cable bunches that are used today. For testing, signal generators were used to generateFSK-signals and were transferred with the help of inductors to the oscilloscope for signal detection, this to see how the coils used in the tests behaved. Simulations of a PLL were performed to see how good it could handle FSK-demodulation. With the help of a PLL IC and the simulations a working FSK-demodulator could be assembled.

The Swedish forest industry has put a lot of resources in the development of digital communications in hopes of improving collaboration with suppliers. The purpose of this study was to investigate whether VIDA would benefit from using digital communication with suppliers. The survey was conducted as a questionnaire study among the company?s staff and its suppliers. The result indicated needs and interests to use digital communications in both groups. Young suppliers and suppliers on a distance showed the most interest in using digital communication. In terms of using these digital communications, the staffs and suppliers were most interested in information regarding transaction and forestmanagement plans.

We are in an emerging digital society where we are increasingly dependent on the mastery of IT and digital technologies to better carry out our everyday tasks. They cover everything from keeping in touch with family and friends to pay bills and declare. At the same time there are those who have not learned how to use the new technology and live their lives outside of the digital society. What happens to these people, in a society that is becoming increasingly digitized? Do they take harm by being in digital exclusion? It looks like this are issues that will not become less important as digital technology constantly changes.

There is little doubt that the digital technology has played a major role in reshaping the ways in which we experience the world. In a few decades the Internet has become a vast repository for knowledge and ideas. New arenas where people may meet and fraternize have emerged, and with the help of various digital tools and websites, the production of new material has increased to an almost unfathomable level.But all is not well on the digital front. As the Internet has become a crucial part of our everyday life, certain skills in handling digital media has become very important to master. A well-developed ability to navigate through this ocean of information is needed, and knowledge in managing the risky nature of the internet is critical.

This thesis discusses the possibilities to distribute digital video in a military vehicle. Today, an analogue system is used, which has a maximum capacity of eighteen video sources and the same number of monitors. The purpose of this thesis is to increase the systems capabilities regarding secure distribution and additional functions. Both software and hardware tests are made to investigate the features of the digital video standard MPEG-2. Both the coding delay and the image quality are of great interest.
