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 study is to examine the roles of the children?s librarian in a reading aloud context. To reach understanding in this subject, we have conducted interviews with four Swedish librarians working in public libraries whom are involved with reading aloud practices. Previous research shows that the reasons for reading aloud in libraries are diverse and plentiful. Such reasons can be to spread cultural experiences, help children develop their language skills and promote the library to the public.

This is a master degree thesis at Royal Institute of Technology (KTH) betweenÅngpanneföreningen and Programma. KTH is the examiner, Programma is the client andÅngpanneföreningen is mentor for this project.Programma has a product called TM1800 that has problems with EMC; the problem is thatthis product does only pass the CE-check with a small safety margin. This problem can besolved by reducing the radiation from the electric components in the product or by reducing offix base frame. In this degree thesis the focus is only on mechanical redesign.The main problems right now depends on the long distance between the screws, there is anisolating layer on most of the parts and the forces between the joints are too small. The mainfocus is to solve these three problems.The best solutions are when the whole base frame is more or less redesigned instead of onlyredesigning some of the connection points.

Voice over IP (VoIP) is a relatively new technology that enables voice calls over data networks.With VoIP it is possible to lower expenses, and increase functionality and flexibility. FromSwedish Armed Forces point of view, the security issue is of great importance, why the focus inthis report is on the security aspect of the two most common open-source VoIP-protocols H.323and SIP, some of the most common attacks, and counter-measures for those attacks.Because of the level of complexity with a network running H.323 or SIP, and the fact that it hasyet to stand the same level of trial as of traditional telephony, a VoIP-system includes manyknown security-issues, and probably at present many unknown security flaws.The conclusion is that it takes great knowledge and insight about a VoIP-network based onH.323 or SIP to make the network satisfyingly safe as it is today, and is therefore perhaps not asuitable solution for the Swedish Armed Forces today for their more sensitive communications..

Introducing a new type of IT-structure means a change that employees within an organization must adapt to. Today, many companies have implemented information technology in the form of Enterprise Resource Planning (ERP) Systems and find themselves in th so-called Second Wave stage where an after work is ongoing with continual improvement that involves changes that employees need to understand and act upon. To learn how to work with these recurrent misadventures is of importance because it is seen as a critical factor in order to take advantage of the ERP system and its benefits. To study this a study was conducted through personal interviews at Apoteksgruppen AB which a few years ago introduced a new ERP system. There the authors saw that employees learned in different ways depending on the position, and that the more responsibility this person had the greater freedom this person had to resolve their problems and therefore learned more effectively.

This thesis work has been performed at the Division of Assembly Technology at Linköping University for a period of ten weeks. The work is part of the project ProFlexA, which is a research project in collaboration between Linköping University, Lund University, and industrial partners such as Combi Wear Parts and Smålands Stålgjuteri AB.The casting process creates random incurred burrs and defects, which must be removed during a cleaning process to make sure that the cast can be sold. Automation has long been sought for the cleaning of castings due to, among other things, poor working conditions for staff, but this has proved difficult to implement with today's technology. Automation has for some time been available for more capital strong companies with large annual volumes, but for smaller companies with small-and medium-sized volumes, automation has not been an option.The goal of ProFlexA is to develop an automated cleaning cell aimed at small-and medium-sized volumes.The goal of the thesis is to do a pre study at ProFlexA?s partners on cleaning of castings, and develop concepts for automated cleaning of castings.By recording the process and cycle times, the cleaning of castings has been documented as it works today, and on this basis, information and statistics has been compiled.

This user study was carried out at the library at Chalmers University of Technology in Gothenburg in the spring of 1999. Chalmers wanted to investigate how much their employees use electronic journals. To facilitate decision-making and be cost effective, the library needed to know about their customers' opinions. The main purpose was to investigate the usage of electronic journals, how the library's choice of these journals affects the frequency of use and what the attitudes towards them are. A questionnaire was sent out to 2 400 employees; 477 replies were received.

Detta examensarbete har genomförts på uppdrag av Outokumpu Technology AB och bestod i att genomföra dynamiska beräkningar av en punchmaskin i syfte att skapa en bättre kunskapsbas för framtida utveckling Lämpliga aspekter att studera är bl.a: Vilka krafter som uppstår vid slagförloppet samt sambandet slagkraft/slaghastighet. Accelerationer och utbalansering vid slag och förflyttning. Utmattningspåkänningar i bärande konstruktioner. Vidare så är konstruktionsförbättringar av utsatta komponenter en möjlig del av examensjobbet. Som grund för beräkningarna har uppmätningar av en punchmaskin i drift genomförts och även tidigare mätningar har använts.

St. Jude Medical Inc is one of the worlds leading companies in the medical technology area with cardiovascular devices as its specialty.Manufacturing implantable medical devices such as Pace Maker Electrodes requires complex design, safe processes and well trained operators. User friendly manufacturing operations are a necessity.Lately there?s been an increase of the manufacturing volume which also increased the number of operators. More operators need to be trained and cross-trained.

The purpose of this thesis is to increase the understanding about consumer buying behaviour when purchasing books online. In order to acquire data for the study we used a questionnaire that 75 students where asked to respond. The respondents were students at the University of Technology in Luleå. Our findings suggest that the following factors are the most commonly cited reasons for deciding to complete the purchase: trust, perceived risk, price, convenience, design of the website and experience. The following factors are the most commonly cited rea-sons for deciding not to complete the purchase: trust, perceived risk, price and the design of the website.

Helsingborg has the intention to build a train tunnel south of Knutpunkten. This report investigates the hydro geological aspects of the project. Questions at issue that will be answered: 1. Which parameters affect the groundwater level? 2. How will these parameters change within 100 years considering climate changes and what will be the consequences on the groundwater level. According to SMHI climate analysis the climate can change causing increasing precipitation, temperature, and a rising sea level.

Petro-electric IFVs (Infantry fighting vehicles) or hybrid-IFV?s are not a new phenomenon. During the 1900?s Germany as well as the U.S both tested vehicles constructed with hybrid technology. In spite of several identified advantages, no serving hybrid-IFV exists today.

In 2010, Airwatergreen AB started testing their new technology, the Airwaterwell, an atmospherical water generator of their own design that is running on solar heat, with a production capacity of three litres of water per day and m2. The purpose was to focus on foreign aid organizations as main purchasers for project investments towards rural communities in developing countries that suffer from lack of, or compromised quality of drinking water. In order to further understand if this technology would bring a positive impact in the developing countries, the company contacted the Swedish University of Agriculture for a socio-economic study of the Airwaterwells? potential. The authors elected Cost benefit analysis as the appropriate method for conducting the study and India became the study region because of its many problems with water related issues such as diseases as well as insufficient water supply for households. The regions that this study is based on are Gujarat, Haryana and Uttar Pradesh given their differences in income, health situation and poverty rate.

The aim of the study was to explore how persons with aphasiaexperience literacy and reading and writing. Seven persons with mild-moderateaphasia were interviewed. The interviews were recorded, transcribed andanalysed using qualitative content analysis. The analysis resulted in three mainthemes; A changed reading, A changed writing and How to adjust andaccommodate to new conditions. The most apparent aspect was that theinformants experienced that literacy had changed, regarding what and how theyread/write.

For the last 50 years the amount of available consumer goods has exploded in number, due to improvements in production and technology. The problem is that the overall sales of many categories are stagnant and retailers are unwilling to grant the categories more shelf space. Therefore many categories are crowded with products and hard for consumers to navigate in. The purpose of this paper is to examine the effects of an assortment reduction on several variables relating to assortment perceptions, customer satisfaction and store choice. The study was carried out as an experiment with 127 participants.
