The empirical material is collected through an inquiry and several interviews with scinentists at the ten universities of Sweden. This inquiry was done within the timeframe of November 2000 to Janurary 2001. The purpose is to find out wich methods scientists use to spread their knowledge to the society and what possibilities there are to improve these..

Två olika tårsubstituts påverkan av synkvaliteten

Tårsubstitut används mycket bland linsbärare och personer med torra ögon. Detär vanligt nuförtiden att arbete i kontorsmiljö och vid datorer ger problem medtorra ögon, Computer vision syndrome (CVS), och att dessa personer dåanvänder tårsubstitut. Ofta står det i tårsubstitutens bipacksedel att de kan geproblem med dimsyn en stund efter applicering.Tidigare studier har visat att aberrationerna i ögat ökar vid applicering avtårsubstitut och möjligtvis är det anledningen till att dimsynen uppkommer.Syfte: Syftet med studien är att ta reda på hur mycket synkvaliteten påverkas avtvå olika tårsubstitut och hur lång tid den påverkas.Metod: Metoden innebar att närvisus och aberrationer mättes på 30 patienter (60ögon) först utan tårsubstitut. Sedan applicerades det första tårsubstitutet(Systane) i höger öga och ytterligare en mätning av närvisus och aberrationerutfördes. Därefter gjordes ytterligare 5 mätningar av aberrationerna, en var fjärdeminut.

Universell Design - en användbarhetsutvärdering av MyTobii C-series Control

Universal Design is a well established methodology with the fundamental purpose of designing products to be usable for as wide audience as possible, without the need of special adjustment to suit the individual. In this essay, Universal Design has had a clear influence in both the process and the result. The choice to use Universal Design as methodology in this usability evaluation, has essentiallv to do with the target audience.As a part of the design process of MyTobii C8 has Tobii Technology ask for a usability evaluation. MyTobii C8 is an 8" touch screen computer with a windows based operating system which will initiate the software MyTobii C-Series Control. MyTobii C-Series Control is the control panel for MyTobii C8, whose interfaces constitute the platform for various modificarion of the unit.

Analys och kontroll av hållfasthet på grenställsarm

The thesis was done in collaboration with EAB situated in Smålandsstenar. In the initial discussion faze on doing a thesis with them there was a need to analyze and ensure the strength of an existing product, cantilever racks. This included performing FEM calculations on a model and comparing the results with physical tests.EAB has two models of cantilever racks, a light duty and a heavy duty. Within the heavy duty model series there are five product variants that differ in both size and load capacity. We will be working with the product variant with a load capacity of 1000 kg/arm which is the variant that is in the middle of the series.When we started work on the thesis we did a literature study and couldn?t find any well defined methodology that integrates both product development and computer aided design analysis.

Läs: spela!

Abstract Svanvik, Robin (2013). Läs: spela! En jämförande studie av elevers uppfattningar om datorspel, skönlitteratur och lärande. Svanvik, Robin (2013). It Reads: Play! A comparative study of students' beliefs about computer games, fiction reading and learning. This essay is part of a masters degree of pedagogy and investigates the experiences of 10 high-school students concerning playing computer-games-off-the-shelf (COTS) on the one hand, and reading fictional, printed novels on the other. The aim of this study was to learn more about the students' thoughts about playing COTS and reading novels; also, what differences and similarities there might be between these activities. Furthermore, I wanted to know what they thought they might learn from these activities. The theoretical point of departure for the study is twofold: Firstly, a theory of learning as expressed by Illeris (2007) and, secondly, a sociocultural perspective on learning, represented by Säljö (2000, 2005/2010) which includes the educational benifit of both playing COTS, represented by Gee (2007), and reading fiction, represented by Probst (1990) and Langer (1995). The method used in this study is mainly qualitative by nature.

Soft Softer Sopho : Utformning av ett användbart användargränssnitt för mjukvarutelefoner

Internet is the future and VoIP (Voice over Internet Protocol) is growing in use. Companies are starting to realise the benefits with VoIP. Skype is the number one soft phone on the market but it doesn't satisfy the needs of companies (e.g. transfer calls, redirects calls and so forth) and leaves therefore a gap. The purpose of this master thesis is to provide Objektor AB (thesis initiator) with tips on how to design a usable soft phone that they know is based on relevant human computer interaction research.The method used in the thesis has been iterative development.

Underhållskostnader på rundbalspressar :

Costs of maintenance on agriculture machines is something that many farmers has a low knowledge of, it can depend on low interest or that the farmer don?t have enough time. To make it easier for the farmers they can use many computer programs which are available on the market. In this program they can calculate their costs of maintaince on their agriculture machines, for example STANK and JTI machine calculation program. Most of this program is using Svensson (1987) costs model whish was made in Sweden in the middle of 80 decade in a large study.

Hinder för fysisk aktivtet hos ungdomar i övre tonåren

AbstractEmilia Rönnberg.Barriers to physical activity in adolescents in their late teens. Vetenskaplig C- uppsats HT 12 Physical activity has been essential to human health and well-being since several thousand years. In Sweden, it has been shown that both adults and young people are less physically active than the rest of Europe- a large proportion of young people today do not meet the recommendations for physical activity (60 minutes per day). The purpose of this study was to determine what proportion of young people, i.e. high school students, did not meet the recommendations for physical activity.

Artistskatten och dess betydelse - en komparativ studie mellan Sverige och Danmark

Denna uppsats beskriver skillnaderna mellan svensk och dansk beskattning beträffande såväl inhemska som utländska idrottsmän. Sverige dammsugs på spelare på grund av att de danska reglerna är mycket förmånliga i förhållande till de svenska för utländska artister. Många svenska klubbar försöker kringgå full beskattning med hjälp av en så kallad signing bonus..

Only recently did bibliometric indicators become one out of many means for the allocation of financial resources for scientific research at Swedish universities. The purpose of this thesis is to discuss the issue of using citations when evaluating science. The author studied the issue from the perspective of citers? motives.

Umgås på Internet eller på ett café? : ? en studie om Internetanvändningens sociala konsekvenser.

AbstractTitle: See each other on the Internet or on a café? A survey about social consequences of Internet usage. (Umgås på Internet eller på ett café? ? en studie om Internetanvändningens sociala konsekvenser.)Number of pages: 34 (including enclosures).Author: Carolin Johansson.Tutor: Else Nygren.Course: Media and Communication Studies C.Period: Fall 2007.University: Division of Media and Communication, Department of Information Science, Uppsala University.Purpose/Aim: The purpose is to get increased knowledge about the social consequences that may come up when young people at the age of 16-20 are using the Internet.Material/Method: The material consists of a questionnaire that I made with questions about Internet usage that 84 young people from five classes (from three different upper secondary schools) answered.Main results: To have access to a computer and Internet and the fact that broadband is more inexpensive now than before leads to an increased usage of the Internet. I found out that chatting, music/movies, searching for information and using the Internet for entertainment is what most of the participants spent the most time on while using the Internet.

DNS prestanda

Use of computers and computer networks is nowadays a part of everyday life. You do not use them only at home when you sit at you computer, but you can use them all the time everywhere. This can involve everything from surf to any website when you are at home, to checking your email on your mobile when you are on your way to work. Most people do not think about how it really works when they try to access a web page by typing the address into their browser, but something that most people probably notice is how long it can sometimes take to access a web page.All items which are directly connected to the IP network have a unique IP address that is used to make it possible to communicate. The IP address is either a period separated sequence of digits representing 32 bits or a colon separated sequence of digits representing 128 bits, depending on whether the address is an IPv4 or IPv6 address.

Normalvetenskapen och dess förutsättningar : Två grader av relativism? - En jämförelse av Thomas Kuhns och Richard Rortys kunskapsteori.

All since Thomas Kuhn?s strongly influential The Structure of Scientific Revolutions the Philosophy of Science and ?even more so ?the Social Sciences have contained a greater amount of theories that could be described as more or less relativistic, meaning that the standards of justification or truth thereafter more often were said to be relative to language, culture, or biological makeup. One of the more elaborate ways of developing Thomas Kuhn?s theories in a more relativistic direction ismade by the philosopher Richard Rorty. Rorty, mainly a supporter of Thomas Kuhn, is also a philosopher who has been seen as a main exponent of a so called Postmodern philosophy.My intention in this thesis is to evaluate whether Kuhn's and Rorty's theories of science and knowledge could be regarded as relativism, in respects of their view of incommensurability, rational argumentation, and of their position vis-á-vis the more conventional picture of scientific knowledge and truth.

C, C++, Java och Python : En prestandajämförelse mellan fyra programmeringsspråk

In today?s society computers are getting a much more important role. To get a computer to work as intended it has to be programmed. A computer program is written with programming languages.

Mot en delad framtid? : Mendeley som exempel på vetenskaplig kommunikation online

The last few years have been characterised by increasing online communication and the emergence of social media, made possible by Web 2.0. In society as well as in research, social media is used for knowledge produc- tion and networking. One example of this is Mendeley, a social reference management tool. With answers from users all over the world, this study investigates the use of Mendeley, if the respondents use other social media and if all of this affects scientific communication. The aim is also to study what the respondents think about the future of scientific communication and if this can be related to current tendencies.The theoretic framework for this study is based on Leah Lievrouws research on the Cycle of Scientific Communication and the relationship between the ?Little Science 2.0?-scenario and the ?Big Science Retrench- ment?-scenario.A qualitative web based survey was conducted (41 answers) and complemented with an interview with a professor in environmental sciences.
