Hur påverkar ny teknik företags relation och kommunikation mot sina kunder och leverantörer?: En studie av fyra företags utnyttjande av moderna affärssystem och effekterna i kund- och leverantörsrelationerna.

This qualitative case study, made with four companies, looks closer at how more effective information management, with the help of IT-systems, affect companies market communication and relations to customers and suppliers. Customer Relationship Management perspective is used and Enterprise Resource Planning-systems are the ground for new technology change. The main conclusions are that new technology affects the outcome of companies? relationships towards their customers and suppliers and that the processes and activities between the involved parties are more closely linked. Also involving your suppliers and external actors makes the information handling more effective and companies that do so most likely have a competitive advantage..

Systemanalys av skogsbränsletransporter :

At the end of 70s and the beginning of 80s, 18 terminals was built and used for chipping wood residue from clear cuttings. Most of the terminals was terminated before the 2000s but with the high oil- and energy prices that we can see today there might be a place for these terminals again. The goal with the study was to analyze and compare economical differences between 5 different logistical systems, collected data was used with a set of formulas. The systems include long range transport of slash, chips and bundles. Three of the systems include transport by lorry to industry the last two includes a terminal with access to train transport.

Undersökning av mental arbetsbelastning under instrumentflygövningar

En människa har en viss mängd kapacitet för att utföra uppgifter. Om uppgifterna blir för svåra eller för många, det vill säga om den mentala arbetsbelastningen blir för hög, går det inte längre att klara av alla uppgifter och prioritering av de viktigaste uppgifterna blir nödvändigt. Piloter behöver ofta ta in och bearbeta en stor mängd information under instrumentflygning. Ofta måste en del av uppgifterna utföras samtidigt och på begränsad tid. Syftet med examensarbetet är att, med hjälp av en subjektiv mätmetod undersöka vilka moment under instrumentflygövningar som medför störst respektive minst mental arbetsbelastning.

Framgångsfaktorer för rundvirkesåkerier i Mellansverige :

Generally, the economic health of Swedish roundwood truck transport companies has not been good. Profitability is important for maintaining the stability in the transport business, which is a condition for long-term transport planning in the forestry sector. The scope of this study was to identify probable factors influencing the profitability of roundwood truck transport companies and quantify the influence of these factors on economic results. The study was carried out at a major roundwood truck transport organisation in mid-Sweden and was implemented in four steps. In the first step economic results from the haulage contractors were collected and a random sample was taken from accounted net margin for the account year 2005/2006. In the second step hauliers were interviewed to identify probable success factors. At the third step data for identified factors were gathered through a questionnaire.

Tar vi barnens intresse för natur och teknik på allvar? : En kvalitativ studie om hur några förskollärare resonerar runt möjligheterna att ta tillvara barnens intresse för naturvetenskap och teknik i förskolan

The purpose of this study was to examine and compare what six preschool teachers thought about their opportunities to take advantage of children's interest in natural sciences and technology, across four kindergartens. The following questions were explored in order to achieve the aim of the study: How do the preschool teachers interviewed describe their work with science and technology in the preschool and what these preschool teachers think about the meaning of motivation in the children?s learning of natural sciences and technology in preschool.  The study used a qualitative approach in the form of semi-structured interviews and interviewed a total of six trained pre-school teachers from four kindergartens with different profiles. The first kindergarten focuses on mathematics, science and technology.

Perspektiv på lärplattformar : Hur tekniksyn påverkar användandet av lärplattformar på universitetet

Information technology inflicts upon us in our everyday life. It is a natural part of our work and of our spare time. The education system is not excluded from this development, IT is becoming an important part of education at all levels. In university, learning platforms is one of these new ways of using IT in education. Learning platforms becomes a valuable tool for teachers and students.

När tågen slutat gå : förvandling av övergiven räls till publikt promenad- och parkstråk

Abandoned and unused railway structures often possess great potential if they are reclaimed and reused for new purposes. The thesis focuses on the global trend of restoring and revitalizing these areas, converting them into park areas, rail trails and green corridors in the city landscape, while preserving their ecological, social, esthetic and historic values. These rail areas were often abandoned when industries moved out from the cities, either to industrial areas or abroad. The use of railways for transporting industrial goods was also replaced to a large extent my motorized road vehicles in the mid 20th century, leaving the rails under-utilized. Because of their location and intrinsic values, they can be reused for important functions, such as green areas in the city environment, providing space for recreational activities and exercise and social meetings and interactions. I have closely investigated the three park areas High Line in New York, Promenade Plantée in Paris and Schöneberger Südgelände in Berlin, which have all gone through this transformation in recent years. I have summarized my conclusions in three key concepts to consider: design for social values, preserve the architectural history, and leave room for future evolution. The final part of my work is a design program for an abandoned railways area in Stockholm: Eriksdal railway area.

Factors influencing pig behaviour during unloading from a transport

Transportation of pigs might be a welfare problem. Stress during and after transportation can negatively affect the meat quality or cause carcass damages, which leads to major economic losses every year. The transportation chain can be divided into several stages; loading, transport and unloading. This literature review focuses on unloading of pigs from a transport. When arriving at an abattoir pigs can be fatigued and need to be as smoothly unloaded as possible.

IT-Instrument : En intervju-och observationsundersökning kring användandet av digitala instrument inom undervisningen i ämnena historia och engelska i en gymnasieskola

This essay is a study of the use of IT technology by teachers of English and History at a Swedish upper secondary school. It is based on four interviews and four observations. In my analysis of these I have made use of the theory of Social Shaping of technology, a theory which puts emphasis on a teacher´s purpose regarding the use of IT technology in order to empower the teaching process. As a researcher I aim to explore the reasoning on the part of the teacher and to that end I use the method of interviews and observations. This study shows different ways of using IT technology varying from one teacher to another.

Jämförande simulering och modellering av framtida järnvägars elenergiförsörjning

In this thesis, the Train Power System Simulator (TPSS) has been compared and verified with the commercial simulator TracFeed® Simulation (TracFeed). The basis for the comparison was a given part of the Swedish railway system, with steel transportation trains. Primarily, emphasis was placed on running time and energy consumption in simulation results. Two transformer systems were analyzed, booster and auto transformers. The high voltage transmission line, parallel to the railroad track, was disconnected in some simulations.

HelpSeat

The Smart Grid technology has during the last decade been established as a way to create a greater flexibility on the electricity grid that will be needed as the development moves towards an increased share of renewable primary energy sources in the electricity production. One part of the Smart Grid technology is the ability to shift loads in time, to adapt to either price or emissions, known as Demand Response. This project, which was conducted at KTH in collaboration with the consulting corporation Capgemini, examines the economic, environmental and social aspects of the Demand Response technology. In the project, three household products are used in a model that derives the potential savings in costs and emissions of CO2e. The results show that the actual savings measured in SEK are small, but that the savings measured in percent can be as high as 20 percent. Reduction of CO2e emissions is slightly lower.

Tidsåtgång för rundvirkesmottagning på Södra Cell Mörrum

This study was made for the round wood transport company MT Transport AB. Time studies were made in order to analyze time consumption on the mill site for timber trucks delivering round wood at the Södra Cell Mörrum mill. The most interesting was to see how much of the time spent at the factory that was waiting time. In three weeks the study was going on and the drivers were clocking it themselves..

The technology system is called EDIT (Educational Development through Information Technology) and has been developed and applied at Linköping University?s Faculty of Health Science. EDIT supports Problem Based Learning and enables scenarios to be presented through the World Wide Web. The study was divided into two parts.

Användaracceptans vid systemimplementering.

Användaracceptans är en viktig del i alla systemutvecklingsprojekt och är också en väldigt lättpåverkad variabel för en lyckad implementering. Därför är det viktigt att ha översikt på sådana faktorer som kan påverka användaracceptansen negativt, en sådan faktor är försening. Denna uppsats belyser sammanhanget mellan hur en försening påverkar användaracceptansen. Genom att låta en undersökningsgrupp genomgå en enkät utformad efter Technology Acceptance Model har jag samlat upp en generaliserad åsikt. Resultaten visar att försening som variabel inte påverkar användaracceptansen för fallstudien..
