Computational thinking was brought to the forefront in 2006 by Jeannette Wing. Computational thinking is a problem solving method that uses computer science techniques.The thesis is analyzing computational thinking and how it could be applied to graph theory. Characteristics and main fields from computational thinking is being analysed. This analysis is applied to graph theory to see the potential in developing a proposal for how an exercise can look for an introductory course in discrete data types. Only basic knowledge of graphs is required to perform the exercise.

The aim of this Masters thesis is to examine librarians attitudes and values when it comes to the question if a new media, video games, should be introduced at the library or not. Video games are here seen as media primarily for youths. In our study we also wanted to study the discussions of quality and purchase, when computer games were introduced at the library. In order to answer our questions we conducted nine interviews with librarians working with children and youths, in eight libraries. By analysing their statements, using Maj Klassons theory where she defines the librarians role in three different strategies, we could demonstrate how the librarians reason when it comes to video and computer games, youths, quality and purchase.

The main object of this diploma work thesis is about how computer programs can bea tool to use for work on stormwater investigations. The advantage of using acomputer program compared with calculations made by hand is evaluated anddiscussed. The computer programs that have been used for studies and a sequence oftesting of the possibilities are Autodesks Storm and Sanitary Analysis and DHIs MikeUrban.Focus on sustainable development now permeates the building industry. As a resultstormwater investigations have been conducted in an increasing extent the recentyears. Stormwater is water produced due to precipitation, such as rain and snowmelt.Stormwater investigations normally contain descriptions of existing land use, plannedland use and suggestions of measures and technical solutions for the future disposal ofstormwater.The initial part of the thesis consisted of literature studies on stormwater andstormwater investigations to understand the science.

Titel: Kommunicera rätt! ? En studie om kommunikation mellan systemutvecklare med kundkontakt och kund. Författare: Peter Johansson Oskar Hanson Handledare: Johanna Törnquist Examinator: Guohua Bai Problemområde: Anledningen till detta examensarbete är att problem som kan uppstå vid systemutvecklingsprojekt vanligtvis har sin grund i kommunikationen mellan systemutvecklare med kundkontakt och dess kunder. Exempelvis hör en systemutvecklingsgrupp och ett bageri till två vitt skilda yrkesområden och därmed pratar de ?olika språk?, vidare kan det skapas semantiskt brus i kommunikationskanalen som i slutändan kan leda till en felaktig kravspecifikation och de verkliga förändringsbehoven förblir oupptäckta. Hypotes: Examensarbetet baseras på hypotesen: ?Semantiskt brus[1] i kommunikationskanalen[2], otillräcklig negativ feedback[3] från sändare[4] och mottagare[5] och svårighet att hitta rätt nivå på samtalet med hjälp av kodning[6] och avkodning[7] ger upphov till en felaktig bild av kundens verkliga förändringsbehov[8] .? Slutsats: Alla delar ur Shannons kommunikationsmodell tillsammans med cybernetikens negativa feedback påverkar resultatet vid framtagande av kravspecifikation. Delar som både teori och respondenter tar upp är att som konsult måste denne ?kunna tala kundens språk?, hitta rätt nivå på samtalet, ge och ta negativ feedback samt undvika semantiskt brus i kommunikationskanalen.

The Swedish energy companies have several different systems for data collection of the energy consumption of their clients. Often computerized remote meter readers are put in practice in order to register the energy consumption of large companies. The majority of household clients, however, are read off by the assistance of manual methods. Household power consumption is read off once a year. As a result, these clients are not debited for their actual consumption; their invoices during the year are the result of estimations. At times when the electricity supply system is highly loaded, electricity is more expensive.

Context. In today?s society we use smart cards in many areas, NFC is a smart card technology that allows contactless interaction between a reader and the tag, the tag is often in the form of a card. NFC can be used for various payment methods or as access card to a building which makes life easier. In previous studies, the technique has proven to be weak to attacks using an NFC reader connected to a computer.

Detta arbete är en reflektion över ett programvaruutvecklingsprojekt, WAIS, och den arbetsmetodik som användes för detta projekt. Arbetsmetodiken för utvecklings-projektet var Extreme Programming (XP) och vi ifrågasätter om detta val var lämpligt för ett projekt som WAIS. Projektet genomfördes vid Blekinge Tekniska Högskola under våren 2004. Utvecklingsprojektet WAIS var en del av ett större projekt, AIS 42, som stöds av VINNOVA. Huvudprojektets bakgrund och syfte beskrivs för att läsaren skall förstå den roll projektet hade. Studenternas uppgift har varit att utveckla en prototyp för ett system som skall sprida information relaterad till logistik och transporter.

In the history of scientific visualization techniques there is a lack of social science practices and methodologies. The advent of modern computer graphics brought the use of visualizations into a whole new era, but even though the tools by which such modern visualizations are created become easier to access and use, the lack of social science researchers harvesting the benefits of such tools still remain. This ease of use, increase in power and accessibility plus the ever growing need within the natural sciences to augment the human senses has further complicated the relationship between scientific methodologies, validity, reliability and the use of visualization techniques. This relationship must be explored, demystified and understood in order to fully grasp the impact of visualization practices when incorporated into any given scientific method. Within the social sciences there is one example of a tradition that has since its conception carried within it a graphical notion and a visualization practice.

Mitt projekt är en film i 3d med en skräckfylld underton som utspelas genom en fiktiv persons ögon där färden går genom en skog fram till vad som ser ut att vara en nedlagd fabrik. Men där tystheten från början råder visar sig både det ena och det andra utav märkligheter uppstå! Effekterna för den mörka upplevelsen är prioriterad framför en begriplig handling, och därför finns inga övertydliga budskap som underskattar betraktarens egna slutsatser av filmen. Filmen är ett experiment med 3d, postproduktion och ljud som visar en blandning av konkreta spänningsmoment och en morbid känsla av rå död!.

The purpose of our study is to describe and understand whether, and if so, how social workers in school and in social services construct computer gaming adolescents as a social problem. We chose social workers who encounter adolescents with different problems. We have conducted qualitative interviews with vignettes to capture the social workers' reasoning about computer gaming adolescents and how they handle this in their work. The study shows that all social workers we interviewed had encountered adolescents with troubling computer gaming habits. In the study, all agree that computer gaming becomes a problem when it leads to deviant behaviour such as not going to school, staying up all night and so on.

Human-computer interaction is central for computer assisted development. The aim was to investigate the user experience of a new (U2) compared to an old (U1) computer system, within a cognitive psychology frame of reference. Six subjects, frequently using the system, participated in the study. It was shown that the new (U2) compared to the old system (U1) enhanced and supported more the users? system related procedures/tasks.

The project is a practical and theoretical test of IP telephony with Skype in order to form a base for a comparison between IP-Telephony with Skype and the Public Switched Telephony Network (PSTN). PSTN is the common standard that most of us use for telephony today. The objective for the study is to simplify the choice between PSTN and IP-Telephony for the Swedish private customer user group. The project is supposed to answer the following questions. - How easy is it to start using IP-telephony with Skype? - How is the quality of IP-telephony compared to PSTN? - Are all services provided by PSTN available and accessible using the IP-solution? - How are the usability and the availability of support with IP telephony? - Is IP-telephony a cheaper solution and in that case under which circumstances? Within the project a collection of practical and theoretical tests have been performed to be able to form an opinion on the IP-solution in the following areas, installation, function, quality, usability, costs, accessibility and security. In order to study usability, a test group of ten persons have been used to evaluate the usability of the system.

This essay is based on students' growing lack of interest in science at school. Both from a democratic and social perspective, this is a worrying factor for the future. Through observation, I investigated how five science teachers conduct their teaching. This is to get a better understanding of how teachers' behaviour in the classroom can affect students' interest in science. With a socio-cultural research approach, I have tried to highlight a few pieces of the puzzle that may explain students' declining interest in science.
