Pedagogers adaption av surfplattor : En studie av implementeringen av iPad i en F-5 skola
The tablet is a new IT-tool which have started to get introduced into school, but research is still missing and especially in the pre-school environment. The purpose with this study is to investigate teachers uptake, how they use the tablet in everyday pedagogy work as well as the organizational conditions that that facilitate and hinders. Through my observations and interviews in a Swedish K-5 school I have found that the teachers find tablets more appealing to use in comparison to computers. These findings are partly supported by Davis et al.?s (1989) TAM-theory who considers there to be three types of aspects that affect the way individuals adapt to technology.
Sekundärnät för lågtempererad fjärrvärme
Lower energy use in buildings is a result of increasingly stringent energy requirements across Europe. When conventional district heating technology is used in areas with low energy consumption heatlosses do not fall even though the amount of energy delivered is reduced. This reduces income for thedistrict heating company. To maintain their economic viability the district heating companies? majorchallenge is to implement new solutions that minimize heat loss.
En jämförelse mellan Andra Thessalonikerbrevets och Andra Petrusbrevets eskatologi : Den eskatologiska utvecklingen inom två efterpaulinska Jesus-rörelser
The ever-evolving information technology gives users more opportunities, but also put higher demands on them. The digital agenda of the state and society clarifies the objectives and effects academic libraries? development. E-books influence the development of organizational, economic, legal and political perspectives. At the University Library in Gävle work is ongoing. The process is controlled by the acquisition policy which makes it clear that e-books should be purchased if possible.
Eynavster : En studie om teknik som hjälpmedel för synskadade i utomhusnavigering
Navigating to different locations isn?t always easy. Imagine then how it is for people with a visual impairment to walk across the street or to get from one point to another. The Swedish Association of the Visually Impaired (SRF) has pointed out that today's society is not sufficiently accessible to people with visual impairment and there are improvements that need to get done. Technology is something that has evolved a lot this last decade and occurs today almost everywhere in our environment.In some areas, technology has facilitated people's daily life very much and we have therefore chosen to examine whether a combination of several technical functions integrated into the fictive artifact called Eyenavster can facilitate outdoor orientation and increase the accessibility for people with a visual impairment.Qualitative data collection methods have been used in this study by six interviews to answer our question.
Investeringar i klädproducerande fabriker i Södra Indien
Given that the end-customer has become more demanding, the retailer has to deliver products according to the market demands, which have forced manufacturing companies to constantly search for new opportunities to reduce costs and improve efficiency. It is, therefore important to choose suppliers that are able to compete with the market demands.The market demands in the textile industry have lead to shorter product life cycles, which have caused manufacturers to deliver flexibility with high technology to compete successfully on the global market. To achieve the market requirements the underlying factor is to be aware and optimally use and control time. New technology can have a major influence in the production development, if the company choose to take benefit of the advantages, by optimal allocation of the internal resources the productivity and efficiency will increase, to accomplish a competitive advantage. One way to achieve this is by investing in a Unit Production System.In our thesis we have questioned what the main driving forces for an apparel manufacturing company is when it chooses to invest in new technology.
Om kommunalt beslutsfattande kopplat till bostadspolitik. En jämförande studie av två Socialdemokratiskt styrda kommuner.

Nevertheless, people with cognitive and communicativedisabilities have limited access to common communication technology like textmessaging via a mobile phone. This study is part of the project Text messagingwith picture symbols - a possibility for AAC users and people with cognitiveimpairments. Semi structured interviews were used to investigate three menand four women?s experiences of using Windows mobiles with adaptedfunctions for text messaging.
Transporttidsmodellering vid provpumpning i heterogen jord : spårämnesförsök i en isälvsavlagring
When protection zones for wells are delineated, it is important to acquire good knowledge about possible travel time from different points in the catchment area to the well. Often, simple analytical methods are used for estimating travel times and the assumption is made that the hydraulic conductivity is relatively homogenous within the aquifer. Nevertheless, many aquifers are strongly heterogeneous which may lead to differences between estimates and actual travel times. As a part of the process to develop improved methods for delineating protection zones for groundwater supply wells, a tracer experiment was performed in a glaciofluvial esker formation in Järlåsa. On the basis of the experiment, a numerical flow model was created for the test site.The purpose of this master?s thesis was to apply the flow model to an aquifer where the hydraulic conductivity shows great variability and should be described by a stochastic distribution.
Simuleringsverktyg som hjälpmedel vid optimering av signalavstånd inom järnväg : Simulation tool as a help for optimization of signal distances on a railway track
The project Design analysis and proposals of plastic screw caps in Australia was performed at Högskolan Dalarna incooperation with University of Western Sydney, Australia. The Swedish company Tetra Pak, in Lund, were assigner forthe project that was performed 2006-2007. The commission was to do a survey about the packages for non-carbonateddrinks in Australia. The bottles had to be plastic, able to open in one step and with focus on the caps.The project has result in design analysis and a new proposal of a plastic screw cap for the Australian market. Sixbottles were choosen and they were all testet on 20 consumers each with a Likert-scale test.

Utveckling av styrning till solföljande MaReCo-hybrid i Hammarby Sjöstad
Turning solar collectors, heliostats, is certainly not a new idea but has been explored for at least two decades. Projects on this subject have resulted in more or less realistic constructions, in a commercial point of view. Far too often the technical goals have had higher priority than the economical, which has resulted in a few constructions having the ability to compete with conventional, fix solar collectors. The economical issues have been given high priority in this project, without decreasing the demands on reliability. The system has been given the following mechanical and electronical properties: One-axis movement, fix heat carrying fluid system, microcomputer controlled movement and automatic protection from overheating.
Linjenätsutredning i Täby kommun.
The public transport network in Täby commune consists currently of two types of bus line of whichboth belong to the category of feeder lines. The first type terminates at Danderyds sjukhus and feedsto the subway whereas the second type terminates at Täby centrum and feeds to Roslagsbanan, asuburban narrow-gauge railway system in northern Stockholm. The trunk bus line that connectsgreater parts of the commune with Danderyd is the ring line 604 and goes both clockwise (604H) andcounterclockwise (604V). The main negative aspect of this structure is the complicity in incorporatingit timetable-wise with other bus lines that share the same route, such as through Enebyberg.The goal of this project is to investigate the possibilities of splitting ring line 604 and connecting theends to two different bus routes that terminate at Täby centrum today. Apart from easing thecoordination with other bus lines through Enebyberg, the extension also creates new directconnections from various areas in Täby to Danderyds sjukhus.

Changes in the climate and the environment are largely consequences of human influences. Resources are given to teach adults about the environment. However, there are problems in focusing on adults because it is difficult to influence people when they already have created a lifestyle. We have instead chosen to focus on teaching children about changes in the climate and the consequences of this.Many of the toys available on the market today encourage children to consume. Luxury cars and dolls with hundreds of accessories are often made of materials that has have a negative effect on the environment.Another problem we often encountered during the year is the declining interest in technology and science.
??Auktorisation och ackreditering inom Försvarsmakten : En studie i nyttan av en standardiserad process för att hantera informationssäkerhet
???Information Technology is an essential part of the society today, not least in large ???organisations dealing with sensitive information. An example of such an organisation is the Swedish Armed Forces which indeed is in the need of ways to ensure information security in their Information Technology systems. The means which is used is an authorisation and accreditation process.All Information Technology systems go through a life cycle which includes realisation, usage, development and liquidation. In the Swedish Armed Forces the lifecycle is an authorisation process.
