Erfarenhetsöverföring inom markarenan med stöd av simulatorteknik. : En studie av StriSimPC.

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.

Kontinuerlig RFID-detektering för batteridrivna system

This report deals with RFID systems and how to detect nearby tags with the Mifare standard using only a microcontroller and an antenna circuit.The aim was to investigate whether there was any possibility to continuously search for a nearby tag for a system operated with batteries without compromising   the lifespan of the battery. At this time the system would take too long time to wake up and look for a tag to give a satisfactory battery lifespan, which should be done a couple of times every second.The report has two issues, namely:Is it possible to direct the microprocessor to detect and identify a nearby tag after the Mifare standard?What hardware is required for this to be possible?As the research method to provide answers to the above questions an action research was used. This approach has meant that the group worked on information retrieval, examined existing solutions, tested their own solutions and documented the results.The group examined an existing solution that can search for nearby tags with minimal energy consumption. An antenna circuit was built that was connected to the processor.


Spelvärlden som informativt grafiskt gränssnitt : En studie om hur spelvärldens visuella uttryck hjälper ovana spelare att förstå mål och regler

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.

"Smartphonen är som en egen liten hjärna". En kvalitativ studie om specialpedagogers syn på smartphonens användbarhet som pedagogiskt hjälpmedel för elever i behov av särskilt stöd i gymnasieskolan

Purpose: The purpose of the present study is to investigate whether and how nine teachers of special education for older students, primarily at Upper secondary school, consider the smartphone an appropriate pedagogical means of assistance to improve participation and to support students with special education needs within and outside the school environment. Theory: The theoretical framework for the study is the sociocultural perspective on learning. The sociocultural perspective is related to the relational perspective and sociocultural learning theory involves learning and participation in school. It views the human being as socially active within a certain historical and cultural context which actively influences the way we act, how we learn and develop through interaction with others in the social, everyday practice. The latter is of vital importance here.

Frihet under ansvar eller sann och opåverkad kunskap ? Trovärdighet hos källor och hur den bedöms av två användargrupper.

This essay is investigating what type of sources we trust, depending on how the information in these sources is created and provided. To exemplify, the sources Wikipedia and Nationalencyklopedin (the Swedish National Encyclopedia) were used, each one representing different approaches. The first is a representation of the collective intelligence, where anyone can contribute with their knowledge to the public ? freedom under responsibility. The latter represents peer-reviewed knowledge, desirable enough to have people paying for it? true and unaffected.Based on theories of source criticism, collective intelligence, expertise and the different generations of digital natives and digital immigrants, two focus groups were conducted and analysed.

The fit of all-ceramic crowns produced using different digital impression systems

Syfte: Att jämföra marginell och intern passform på kronor framställda genom fyra olika digitala avtryckssystem med kronor framställda genom konventionell avtrycksteknik, som kontrollgrupp. Metod: Femtio helkeramiska kronor framställdes från 50 standardiserade provkroppar, som delades in i fem grupper, där varje grupp representerade ett avtryckssystem. Varje krona cementerades på sin respektive provkropp och sektionerades till fyra segment. Den marginella och interna passformen mättes i 8 fördefinierade punkter. Totalt 1567 mätningar utfördes, analyserades och jämfördes. Resultat: (1) Gällande marginell spalt kunde inga signifikanta skillnader hittas då kontrollgruppen jämfördes med vart och ett av de digitala systemen. (2) Lava? hade mindre marginala spalter än CEREC® och iTero®, (3) CEREC och Lava hade mindre spalter i chamfern jämfört med iTero och kontroll, (4) E4D® visade mindre spalter än CEREC i mätpunkter 4-8 och CEREC visade en mindre spalt i mätpunkt 2, (5) Lava visade mindre spalter än CEREC i mätpunkter 1, 3 och 5-8.


Varseblivning av objekt i digital grafik : påverkan vid förändring av textur.

Syftet med detta arbete är att undersöka hur förändring av material påverkar varseblivningen av objekt när formen lämnas oförändrad. Detta kan vara av intresse då spel med realistisk grafisk stil blir mer och mer högupplöst vilket samtidigt ställer högre krav på de grafiska utvecklarna att framställa verklighetstrogna material.Jag har utfört en kvalitativ undersökning med personintervjuer av sex personer. Dessa sex personer har fått se tre objekt där de fått definiera objektets syfte. Intervjupersonerna fick sedan se objekten med olika material där mina frågor haft som mål att få respondenten att motivera uppfattat material samt det uppfattade materialets egenskaper. De intervjuades motiveringar om objekt och material har jag sedan tolkat utifrån litteratur om psykologi, främst om kategorisering som George Lakoffs bok "Women, Fire, and Dangerous Things" (1990) beskriver.Min undersökning har visat att uppfattningen av textur kan förändra ett objekts syfte och funktion.

Hantering av verksamhetskrav : Utredning av hur hantering av verksamhetskrav från kunder kan förbättras på Saab Aerosystems

Saab Aerosystems have had one dominating product, JAS 39 Gripen, and one dominating customer, FMV, for a long time. The operations management system at Aerosystems is adjusted for development of Gripen and as the business unit is trying to enter new markets with other products and customer the operations needs to be adjusted to fit the development and manufacturing of these products as well.The purpose of the master thesis has been to investigate how Aerosystems is managing requirements on operations from external customers and how to make improvements within this area. The aim has been to carry out a situation analysis to identify where improvements are possible and then produce proposals for improvements through studies of literature and other business units. The thesis also include a study of knowledge transfer within the business unit to investigate how this can be applied to improve the managing of requirement on the operations.An extensive interview study has been carried out in which interviews mainly have been conducted with employees at Aerosystems, but also at Saab Avitronics and Saab Aerostructures. The reason why these business units have been examined is because they have carried out a large number of successful businesses with external customers, which also are potential customers for Aerosystems in the future.The interviews have been analysed to identify strengths, weaknesses, opportunities and threats with the present way of working.

Trådlös överföring av styrsignaler

Anledningarna till att använda sig av en trådlös signalöverföring i en industri kan vara många, oftast handlar det om ställen där det är svårt eller omöjligt att ha en trådad förbindelse. I det här fallet är det en sedimenteringsbassäng där man tar hand om processvatten från industrin. Bassängen är utformad som en cylinder där vattnet rinner genom olika avdelningar för att minska innehållet av sediment. I bassängen cirkulerar en plattform med diverse omrörare och skrapor på. Eftersom denna del går runt hela tiden är det svårt att ha en fast förbindelse till de drifter som finns.

Det digitala skolbiblioteket. En möjlighet för utveckling av såväl verksamhet som yrkesroll?

The aim of this paper is to study if implementation of a school library management system called FreeLib has created favourable conditions for the school librarians to cooperate with other professions and become a more forward working place. I have studied relevant literature about school libraries, organisation, digital libraries and documents that regulate school and library activities today as well in the past. In order to fulfil my purpose I have done a qualitative survey with six school librarians from Swedish primary schools with pupils at the age of 6 -16 years old. To identify strengths, weaknesses, threats and opportunities I found in the material I used a method called SWOT analysis. According to this study the use of the digital FreeLib system has developed a better teamwork between school librarians at different schools.
