Norrborns Industri AB in Bollnäs manufactures truck trailers with the brand Parator. One of their trailers is Parator LX 10-20. The trailer is designed to transport hooklift containers with the option to tip loose goods such as gravel, asphalt and seed. The container is mounted on a frame which is placed on the chassis. To reduce weight a redesign of the trailer is needed.

Direkt viktoptimering (Direct Weight Optimization, DWO) är en ickeparamterisk systemidentifieringsmetod. DWO bygger på att man skattar ett funktionsvärde i en viss punkt genom en viktad summa av mätvärden, där vikterna optimeras fram. Det faktum att DWO har en inparameter som man måste veta i förväg leder till att man på något sätt vill skatta denna inparameter. Det finns många sätt man kan göra denna skattning på men det centrala i denna uppsats är att skatta inparametern lokalt. Fördelen med detta är att metoden anpassar sig om till exempel systemet ändrar beteende från att variera långsamt till att variera snabbare.

This report describes the master thesis project ?Weight Optimization of a Composite Chassis for a Multimodal Lightweight Vehicle? which is a part of the Master program in Naval Architecture and a part of a research project at the Centre for Naval Architecture, KTH. Demands on smart and energy efficient transport solutions are continuously increasing. In the Stockholm region the citizens are expected to increase with 25% and the road vehicles with 80% until 2030, putting high demands on the traffic system. Using a small multimodal vehicle deals with this problem and uses both the land and waterways for transportation.

The purpose of this thesis has been to build a parameterized model of a prototype motor in the program Solidworks, to use in future optimization of aspects of effectiveness and weight. The result were two models. The first model were one minor part of the whole design in 2D, to be able to optimize and study the minor part with a faster loss simulation. The second model was the whole design in 3D. The whole model were done with the three programs Solidworks, Comsol and Matlab.

An old and well known problem in sawmilling is to determine which dimensions /products those are most profitable to produce. Existing optimization models maximize the value of the log. In other words, based upon the market prices of the dimensions the models calculate the best way to split the log. Yet there is a great uncertainty if the most well paid dimensions really are the most profitable to produce. The costs of the process from lumber to sawn products are hard to determine and are therefore often left out from the optimization process. In this study the economic contribution of different dimensions/products are analysed.

Direct marketing is an area within marketing that is growing rapidly. Many companies has realised the benefits of using direct marketing, such as receiving direct response from customers and gaining a better customer relation. The growth within direct marketing means that traditional mass marketing today face harder competition than ever. This thesis examines and look in to three well recognised Swedish companies use of direct marketing. Our main purpose is to establish how companies spend their marketing budget between direct marketing and traditional marketing activities.

This thesis report describes the development of concepts regarding how weight can be reduced to the analytical instrument Biacore 4000. This thesis has resulted in five different concept proposals, all of which is solutions to reduce the instrument's weight.The thesis started with a pre-study where the instrument's structure and function were studied using both Solid Works, the opportunity to study the instrument in real life were also possible done. During this phase, a weight study was conducted as well, in which the instrument's weight distribution was studied and mapped.Following the initial phase, the work proceeded by developing concrete concepts to reduce the weight of the instrument where focus mainly was on the two cabinets. In addition, another two concepts were revealed, both with a more general approach.At the final phase of the thesis, the concepts were compiled and evaluated among themselves and the initial instrument.The thesis resulted in a study of the instrument's structure and weight distribution, with suggestions on how weight may be reduced for the instrument.The result factors such as materials, and manufacturing were aspects that were taken into consideration.At the final section of the report, suggestions for further work in which different aspects are discussed can be found..

The purpose of the study was to examine what methods and strategies individuals use to maintain their weight loss. Another aim was to explore which factors can complicate or simplify weight loss maintenance. Fifty-four individuals who had maintained their weight loss more than a year, participated by answering a questionnaire. The questionnaire was constructed and distributed through the internet. The answers were registered in the program google docs.  The participants mentioned successful methods and strategies, such as exercising regularly, the majority exercised 30 minutes at least five times per week.

AimThe purpose of this degree thesis was to find out what strategies and behaviours earlier overweight individuals have used to maintain their weight loss.- What strategies did the participants use to loose weight?- Which behaviours are related with maintained weight loss?MethodThe study is based on an encase research with earlier overweight individuals who had lost weight with help of the Cambridge method. The chosen population who further more had maintained their weight for over one year have answered questions about their successfully maintained weight loss.ResultsThe results are based on 32 overweighed individuals, 9 men and 23 women, who had maintained their weight loss for over one year. After the initial weigh loss by help of the Cambridge method their main strategy was to change eating behaviour ? by eating on regular schedule, choose food with less fat ? and to increase their physical activity.

Over the past few years the Swedish forestry industry has become increasing interested in direct seeding. Although, in practice, this interest has been restricted to pine seed, the knowledge and techniques that have been developed for pine seeding can readily be transferred to spruce. Direct seeding is a method that is of interest to the forestry industry since it can lead to lower regeneration costs, denser stands and better root development than the more conventional planting method. This study evaluated experiments that focused on direct seeding of spruce in the northern Sweden. Skogforsk set-up the experiments in Gideå and Sävar in 2003.

The aim of this littrature review has been to describe how you can satisfy the need of nourishment for older people who suffer from dementia. Data has been retrieved by searches in Academic Search Elite, Sience Direct, Blackwell, PubMed and in the Journal Vård i Norden. The studies show that most of the people with dementia have a hard time to satisfy the nourishment. The results show that through different preventive measurement you can improve the nourishment for these people, to set the table, play calm music and to have a table companion. By taking the food oneself created a good meal environment and the individually need was provided for.

The thesis aims to examine how companies optimize the human capital from a value creation perspective. The value creation will be related to transfer of knowledge, recruitment, staff turnover and development. The thesis has a deductive approach and six qualitative interviews have been conducted. The results from the interviews will be strengthened with a quantitative data analysis of two measurements; value added per employee and human capital efficiency. The theoretical framework includes definitions of human capital.

Ever since it was first introduced in an article in the Journal of Finance 1952, Harry Markowitz? mean - variance model for portfolio selection has become one of the best known models in finance. The model was one of the first in the world to deal with portfolio optimization mathematically and have directly or indirectly inspired the rest of the world to develop new portfolio optimization methods. Although the model is one of the greatest contributions to modern portfolio theory, critics claim that it may have practical difficulties. Partly because the Markowitz model is based on various assumptions which do not necessarily coincide with the reality.

In this report focus is put on the combustion process at a cement plant. Combustion is the heart of the cement making process and absolutely crucial to have under full control and well optimized. The fuel is put into the process through a burner pipe and this burner pipe is modified to reach a more efficient combustion. The primary target is to enable burning of heterogeneous alternative fuels and increase the production level. Other positive effects from this type of optimization is lowered specific fuel consumption and lowered CO2 emissions. A redundant burner is chosen for the project and overall the project steps are the following: 1. Installing a Jet air nozzle ring in a way so it can move both axially and radially due to temperature changes. 2.
