Utformning av ett materialflödessystem anpassat för HSP-Gripens produktion
Like many small-time companies there is a need to improve the flow of materials at HSP-Gripen AB. The company develops and manufactures hydraulic-powered grapples for the machine- and forest industry. By mapping the material flow in the current production and gathering necessary data, suggestions on how different parts of the production could be controlled is presented in this dissertation. This has been achieved by the study of relevant scientific literature. The suggested ways of controlling the production consist of 2-bin systems, hybrid material flow system as well as a cyclic product-planning.
Skuggvävens effekt på fryslagrade täckrotsplantor av tall (Pinus sylvestris) i upptiningsstadiet :
This project was an assignment by Sveaskog and Svenska Skogsplantor. The purpose was to study the effect of protective fabric on the thawing stage of frozen pine seedlings. The function of the protective fabric is that it should protect the seedlings against strong sunlight and create an even temperature inside the boxes containing the seedlings. The result has shown that there was no statistically significant difference when the protective fabric was used or when it was not used, although this was probably due to the weather conditions. The study was carried out under cold and cloudy weather conditions and probably would have given other results if there had been more sunny days with a higher ambient temperature.
Nollföljdsmodellering av transformator-Beräkningar av följdproblem vid ökad kablifiering på mellanspänningsnivå
Historically transformers with system earth equipment have been modeled as open circuits in zero sequence. This approximation has been satisfying, but lately it has been discovered that equipment on one side of the transformer have responded to faults that occurred at the other side. Most of these problems took place when the majority of the system on the secondary side of the transformer contained cables. These findings have led to questioning whether or not the former model of the transformer in zero sequence is correct. This report investigates if it is necessary to represent the transformer in zero sequence in another way than it is usually done today.
Modernisering av driv- och vändstation för timmersortering
The purpose of the rebuild of Notnäs AB timber sorting line is to renew the existing drive and turning ends of the transport chain, which has become old. This means that Notnäs AB have problems to get new parts if the gearbox and chain are worn out. They also require that the rebuild should have a maintenance schedule for the new spare parts that will be used in the rebuild. Maintenance workers placed great emphasis on that in a rebuild it shall be a service-friendly design. The maintenance schedule used in Notnäs AB in the current situation is from Statoil and the report uses SKF formulas and recommendations in order to obtain a lubricating schedule.
En nutida analys av reseguidehemsidor
In this research our goal is to conclude the aspects of interactivity which can
prove to be important during the creation of a website. The focus in this essay
is websites functioning as travelingguides, because we live in a time of
traveling, experiance and learning.
How can an analyzing method of websites be shaped? What can an analyze of
interactivity on current travelingguides provide for recommendations by the
creation of interactive travelingguides? The analyzingmethod is based on three
shapingmethods and a poll that was answered by both national and international
people. The analyze gave us quite clear results, if you follow the basics of
Use Case, Personas, Usability and design, the website will have a bigger chanse

Tillämpad informationsteknologi i klassrummet
This bachelor thesis in science Informatics contains the qualifications for the applying of IT in education for students in elementary school, grade 1-3. By empirical case study on an existing elementary school, whose success on IT use is noticed, describes how to apply IT in the classroom in an adequate way. We look at different theoretical frameworks in interaction and design of systems designed for learning purposes, and satisfies their specific needs and situations within the classroom's four walls. The current lack of statistical measurements on students' results and effects of the use of IT in teaching, prevents further improvements. If we simultaneously work to develop more well-designed systems that are designed for this purpose, it is possible that the effects become more and better.
Skapandet av en snackis : En studie av marknadsförares väg för att nå ut i reklambruset

They are doing a case study of a marketing campaign which tried to solve the communication problems that clutter is causing. The goal of this campaign was to create a snackis, a Swedish word for a current topic, to reach out with their message. The campaign attracted attention from the media.
Insatser och åtgärder för främjandet av laddelbilar i Sverige
To achieve the goal of fossil independency in the Swedish vehicle fleet in 2030, it would be important to substantially increase the proportion of electric vehicles, both BEV:s (Battery Electric Vehicles) and PHEV:s (Plug-in Hybrid Electric Vehicles). The Swedish Energy Agency has funded numerous research and development projects about electric vehicles in recent years. An important task for the Swedish Energy Agency is to allocate state funds to those projects with the greatest potential to contribute to increased establishment of electric vehicles in society.
The purpose of this work is mainly to understand the efforts and measures that can make the market for electric vehicles to grow. The report can contribute to a better understanding of how far the research on electric vehicles has come and what has to be done in the future to promote the establishment of electric vehicles. Another aim for this report is that it should serve as a basis for future decisions by the Swedish Energy Agency on which projects that will be funded with state funds.
Porslinskonsumtion sett ur ett generationsperspektiv: Köpbeteende - Generationskohorter - Porslinsindustrin
During the latest 50 years, the Swedish porcelain tableware industry has gone from being rather successful to experience significant problems. Our empirical study attributes these problems to underlying changes in consumer buying behaviour, whereas current generation theory supports our findings. The younger generation has significantly different preferences compared to older generations, with less focus on quality and more focus on variability, and there is reason to believe that these findings also are applicable to other consumer purchases. The successful porcelain companies of tomorrow will be the ones that continuously can adapt to these and further changes in consumer buying behaviour..
