Två nya trailerkoncept för transport av rundvirke hos Stora Enso : en analys av prestation och flexibilitet
The need for roundwood transport capacity vary throughout the year. The need during a period is influenced mainly by the volume transported the period, the number of days during which transport can be carried out, seasonal variations in road conditions and the weight of the roundwood, and the origin of the wood (private forest owners/ forest companies). The need for transport capacity generally increase during the winter and in spring, after thawing. Lack of logging trucks combined with a lack of drivers for these trucks make it hard to hire extra help during periods of increased transport capacity needs. It is also very expensive to keep logging trucks for use only during these periods.
In this thesis, two new concepts based on the partial transport by truck tractors have been examined, to find out the possibility for increased performance and flexibility.
Spännkraft på bandavskrapare : Utredning och konstruktion
This thesis was performed at Vendig AB which is a company that develops and sells products such as belt scrapers for conveyor. The thesis is divided into two parts, one part where it´s investigated which tension force is required to tighten Vendig AB´s scraper Hampus against the belt in a correct way. The second part is called mechanical design and here a new and more compact tension device is developed.Field studies has been conducted at a couple of Vendig AB´s costumers to get a knowledge base about how Vendig AB´s products are used, how they function and the environment they operate in. During one of the field studies the force between the scraper and the belt was measured. The result from the measurements, together with a report from LKAB [1], were evaluated and summarized in a table.
Vi skapar barns ordförråd : En studie om barns språkmedvetenhet i förskolan i Sverige och Marocko
AbstractThere is a lot of confusion when it comes to defining Special Education. An example of this appears here by a statement from Assarson (2007) "Special Education initiates a special pedagogy, but contains no innate sense of what is the special component in it" (p. 52, authors? translation). This study is an attempt to clarify the elements of the concept.
Playplus : Utveckling av produktkoncept för aktivitets- och inlärningsmotiverad lek
In a society where adults set the conditions for children?s play and generate modern and at times technically advanced products, fundamental characteristics like simplicity, opportunities for motor skills training and learning tend to be neglected. Owing to this, the Linköping-based company Time In wants to introduce a new multifunctional product, which differs from other products in shape and function and lives up to the often overlooked, basic characteristics in a toy.With Time In as the assigner, the purpose of this master thesis has been to use simple means to produce a "learning by playing" concept. Since Time In sells toys and products suitable for children in nurseries and preschools, the development of the products has therefore included a study of nursery and preschool environments.The thesis has been carried out within the Product Design subject area at the Department of Management and Engineering at Linköping University. Concept development has been done in three phases: the Preparation phase, the Design phase and the Presentation phase.

Lägesbild : Problemområden vid skapandet
Within the framework of the concept of Network Based Defence (NBF) services should be available in the network, in order to increase the aggregate capacity. A common situation picture is one of these services.The aim of this paper is to answer the problem "What are the main problem areas in the creation of a situation picture in the land arena, with the help of the technical sensors that exist today?" and to develop a basis for continued research in the field situation in the concept Networking Enabled Command, Control and Collaboration (NEC3) at JCDEC (Joint Concept Development and Experimentation Centre). To answer the problem, a descriptive method is to be used in descriptions of the land arena, the information arena and the sensors and a deductive method is used when analyzing the asensors in the land arena.The problems that exist in the creation of a common situation picture, is that different types of obstacles makes it difficult for the sensors, the large number of people who are not combatants and that it is difficult to judge if a civilian vehicle is a threat, then it could be driven by civilians or by combatants..
Första plats, andra plats, tredje världen. : En postkolonial studie om hur begreppet tredje världen gestaltas i svenska medier.
The aim of the essay is to investigate how the term ?Third world? is constructed in media. With this I intend to make a historical survey of the conception. With the help of Swedish newspapers and their description of the concept, I am going to answer the following questions: How is the concept ?Third world? constructed in script, in a historical context and in modern time? Is there a tendency of racism in the term?The method I used was discourse analysis.
Att implementra integration En diskussion kring integrationsbegrepp och integrationspolitik med frontlinjebyråkrater som utgångspunkt
The aim of this study is to discuss the implementation of Swedish integration policy from the perspective that public officials, so called front-line bureaucrats, are the real creators of this policy. The concept of integration is far from unambigous; it can have different meanings depending on the theoretical perspective applied. This give topical interest to the question of how the concept is conceived on the national level versus the implementation level. I also aim to uncover how these front-line bureaucrats look upon their role as creators of integration policy. My material consists mainly of interviews with front-line bureauctrats.
"Barnens bästa". En poststrukturalistisk studie av debatten om en individualiserad föräldraförsäkring.
The thesis explores the meaning of the concept "children's best" in relation to the social Swedish parental insurance debate from a post-structuralist view. The main material has been taken from daily news papers and the methodological as well as theoretical basis is provided for by Laclau & Mouffes discourse theory. In particular has the concept "empty signifiers" been of use when investigating "children's best" as a strong argument on both the "pro" and "against" sides of the debate of an individualized parental insurance. The theoretic purpose of the thesis is also to examine the poststructuralist/feminist dilemma in order to approach a more pragmatic and useful model of the two combined provided by Alcoff and Fraser. One conclusion is that "children's best" may never have an objective answer and will be a changing concept in time, ideology preference and discoursive field.
FRAMTAGNING AV INSTALLATIONSKIT FÖR PROJEKTILINMÄTNINGSYSTEM
The report presents a thesis carried out on behalf of the company SAAB Training and Simulation which is situated in Huskvarna. The authors of this report are going to graduate as mechanical engineers focusing on product development and design, and this thesis should reflect the knowledge obtained during the education. The assignment, given from the company was to develop a concept of a stand that will constitute as a part of a mobile system for target practice. The reader get to follow throughout the project and can hopefully learn from the smart solutions and approaches that have arisen during the process.Today SAAB doesn?t have a mobile application in their portfolio that utilizes the benefits of their sensor measuring system, also called the LOMAH-bar.

Detektering av sprickor i vägytor med hjälp av Datorseende
This thesis describes new methods for automatic crack detection in pavements. Cracks in pavements can be used as an early indication for the need of reparation.Automatic crack detection is preferable compared to manual inventory; the repeatability can be better, the inventory can be done at a higher speed and can be done without interruption of the traffic.The automatic and semi-automatic crack detection systems that exist today use Image Analysis methods. There are today powerful methods available in the area of Computer Vision. These methods work in higher dimensions with greater complexity and generate measures of local signal properties, while Image Analyses methods for crack detection use morphological operations on binary images.Methods for digitalizing video data on VHS-cassettes and stitching images from nearby frames have been developed.Four methods for crack detection have been evaluated, and two of them have been used to form a crack detection and classification program implemented in the calculation program Matlab.One image set was used during the implementation and another image set was used for validation. The crack detection system did perform correct detection on 99.2 percent when analysing the images which were used during implementation.
Hållbar Utveckling 2010 : Hur uppfattar lärare begreppet idag?
This work is a study of subject teachers in social studies and science understand the concept of sustainable development. The work uses a qualitative and a quantitative approach. Teachers in various schools and stages have been answering questions about how they perceive sustainability, how they implement it in teaching and if they feel that school is important for the future of sustainable development at large.The theoretical background is based on environmental ethics as well as the different meanings and definitions of the concept of sustainable development. These theories and definitions are coupled with the empirical results.The study concludes that all teachers throughout the study perceive the concept of sustainable development as something ecological, something that has to do with nature. A few teachers also state economic and social dimensions.Questions about how the teachers in the study implement the concept in their teaching can be seen as three different approaches.
Utvärdering av fjädrande statorfötter : Nytt koncept i vattenkraftgeneratorer
This thesis is an evaluation of a new design concept for statorfeets in Gallejaur hydro power plant. Founder of the work is Vattenfall AB Vattenkraft. During the 70- and 80´s nuclear power began to be phased in to the Swedish grid, which meant that hydropower became an important source of rules. The generators began running in so called intermittent operations instead of basic operations, which meant 300-600 start/stop per year instead of one-ten numbers start/stop per year. In order to deal with the thermal forces that arise at every start and stop suppliers began to mount so called sliding joints, which is to take advantage of these forces and maintain the stator shape.
