Stress, kreativitet och problemlösning : En kvalitativ studie i hur vi lo?ser problem under stress och vad detta kan inneba?ra fo?r designprocessen
Problem solving is a big part of design, however a lot of emphasis is put on creativity in research related to the effects of stress. Research has shown that the amount of stress we feel affects idea generation. Stress may also affect the ability to solve problems, however the researchers don?t seem to agree about what the effect of stress actually does.The study was made through experimental sessions where the respondents were asked to solve 4 matchstick puzzles of similar difficulty. Depending on their outcome they experienced more or less stress.
När mormors resa blir digital : Kognitiva aspekter på äldres interaktion med pappersbaserad respektive digital kollektivtrafikinformation - ett situerat perspektiv
Samhällets digitalisering innebär stora möjligheter till spridning och återbruk av informationsamtidigt som digitala klyftor skapas. Bland de medborgare som inte till fullo anammat den nyatekniken återfinns en stor grupp äldre, något som påverkar dessa individers möjligheter till en höglivskvalité i form av delaktighet, oberoende och god rörlighet. En aspekt i detta sammanhang äräldres möjligheter att åka kollektivt och på egen hand planera och genomföra resor, något somförutsätter en god tillgång till och förståelse av kollektivtrafikinformation. Föreliggandeexamensarbete avser här att belysa kognitiva effekter av det skifte i interaktionsmiljön som sker närkollektivtrafikens tids- och linjeinformation digitaliseras. Studien baserar sig på en situerad ansats tillmänniskans kognition, ett teoretiskt perspektiv som innebär att tänkandet baserar sig påmultimodala konceptuella erfarenheter.

Digitala läromedel inom undervisning i trä- och metall slöjd/ digital teaching aid in teaching woodcraft
Detta examensarbete är en undersökning av digitala läromedel i slöjd, då främst ur ett träslöjdsperspektiv.
Arbetet genomförs som ett gestaltande arbete. Detta innebär att arbetet består av två delar, förutom den skriftliga delen har jag även skapat ett anat material i form av ett digitalt läromedel som kan användas i slöjdsalen vid träslöjdsundervisning. Därför består arbetet av två delar, en skriftlig del och en digital instruktionsfilm. Instruktionsfilmen består av både rörliga och fasta bilder i ett bildspel.
Min avsikt med arbetet är att bidra till utveckling av undervisning i ämnet slöjd.
Diskkrypteringsprestanda i GNU/Linux
This thesis compares the impact on disk performance in a GNU/Linux environmentwith three encryption algorithms: AES, Serpent and Twofish in three different implementations: DM-crypt, Loop-AES and Truecrypt. For all three algorithms a key length of 256 bits is used.The thesis shows that the least performance impact during data encryption, and thus file writing, is reached by using AES or Twofish encryption implemented in DM-crypt or TrueCrypt. The thesis shows that some data operations with a sufficiently low processor utilization barely affects disk performance at all if encrypted using the optimal implementation and algorithm.It is also discovered that the performance impact during data decryption, or file reading, can be minimized by using the most efficient implementation and algorithm. The best results are met with the AES or Twofish cipher, regardless of implementation.An important conclusion that is drawn is that it is hard to determine a superior encryption solution for all purposes. However, by reviewing and examining the collected data from all aspects of disk performance the AES implementation in TrueCrypt is, with small marginals, determined to be the most optimal..
Analoga möten i en digital tid - En kartläggning av Socialdemokraternas och Moderaternas dörrknackningskampanjer under 2014
2014 is a special year in Sweden: for the first time elections to the European parliament and the national elections coincides, creating a"Super election year". This year has also seen the rebirth of an old way of campaigning: door-to-door canvassing. For the first time in 50 years the two biggest political parties, the Social Democrats and the Moderate Party, have decided to create a campaign based on personal meetings with the voters in their own home. To investigate this old-new way of campaigning, this study presents an overview of the history of door-to-door canvassing in Sweden and the research in political marketing associated with the phenomena. Based on that, a new model is constructed to help analyze and map the Swedish canvassing-campaigns.
På riktigt : Fyra lärares erfarenheter av blogg i undervisningen
The purpose of this thesis was to find out what experiences teachers have from using a class blog in teaching. What are the advantages and disadvantages by the use of blogs in education?I have used qualitative interviews with four teachers in grades 1 to 6 who have worked with a class blog in teaching between one and three years.The study has shown that teachers' experience is that the blog serves as motivation and promotes learning for many different pupils and that, together with other digital tools is more equal. The main benefits that teacher mention is the expanded concept of text that offers multiple forms of expression and the authentic reader, which makes it more real, important and meaningful. Other benefits that come up are that it helps students to see their learning and learn from and with each other.
"Hur känd kan jag bli på fem veckor?" : En studie om distribution av musik via Internet.
Internet and the digital channels for distribution have meant big changes for the musicindustry. The physical record that has been symbolising this market for a long time is slowlybeing replaced by digital based music. The technical progress during the last ten years has ledto a democratization of music production. The amateur musicians of today can produce highquality music on their laptops and later distribute it via free music sites. MySpace andYouTube are two of the biggest sites for this free distribution and is therefore my main choiseof study.The purpose of this essay was to find out how and if these changes have made a difference formusicians without a record deal to reach an audience by themselves.
Trådlösa Nätverk : säkerhet och GPU
Trådlosa nätverk är av naturen sårbara for avlyssning för att kommunikationen sker med radiovagor. Därfor skyddas trådlosa nätverk med kryptering. WEP var den första krypteringsstandarden som användes av en bredare publik som senare visade sig innehålla flera sårbarheter. Följden blev att krypteringen kunde förbigås på ett par minuter. Därför utvecklades WPA som ett svar till sårbarheterna i WEP.
?Stå inte och häng!? En undersökning av bemötandepolicyer på svenska folkbibliotek
The aim of this Master?s thesis is to survey what personal encounter at the library can signify, and to examine Swedish public libraries? policies for personal encounter. The posed questions are: What does personal encounter at the library signify? How are users and library staff represented in the collected policies?

Of 140 responses, 107 stated that they did not have a written policy on personal encounter.
Resurseffektivt bussprotokoll o?ver RS-485
This report describes the design and implementation of a multi-master, packet based protocol for small and tiny microcontrollers where resources are limited. The protocol was named "Tiny Controller Network" or TCN for short. The protocol is meant mainly as a control bus for automation and sensor acquisition applications but due to its flexibility can also be used for other purposes as well. It borrows some of its functionality and design ideas from the well known CAN bus and Modbus but also has a number of major differences like the use of standard hardware and time synchronisation. One of the key aspects during the design was the use of very little system resources and common on-chip hardware peripherals like a UART.
Frivilliga VD-avhopp En signal på förändring i aktiekurs?
Vi menar att undersöka om vid meddelande att VD avgår enligt vår definition frivilligt, se påverkan på aktiekursen i det berörda företaget både på lång och kort sikt. Om utfallet blir att underavkastning sker i en väsentlig del av händelserna, skulle det ge stöd åt att frivilliga VD-avhopp i de flesta fall vittnar om fallande lönsamhet. Vi genomför en eventstudie där vi analyserar ett visst antal frivilliga VD-avhopp inom två stycken händelsefönster. Där efter ser vi om vi hittar någon avvikande avkastning på grund av dessa frivilliga VD-avhopp..
Är den svenska valutan anpassad för en långsiktigt hållbar utveckling? : ? vilka brister finns och hur kan de åtgärdas?
Money by definition is always a subjective human creation. Because of this it is unavoidablethat the physical and mental structure of a specific money system will have an effect on thesociety where it is circulating. With this fact as a starting point, the thesis is analysing whetherthe Swedish national currency, the crown, is consistent with a sustainable development. Theaim of the analysis is to: (a) identify the major shortcomings of the infrastructure of the crownin relation to its ability to support a sustainable development, (b) evaluate what possiblesolutions there are at hand to adjust for the shortcomings. The method used is purely based ontheoretical analysis, with emphasis on abstraction and causal simplicity.In a modern society, money is not only circulating as coins and bills, but also as digital assetstransferred directly between bank accounts.
