Background: Obesity surgery is the only technique that has proved to have a long-lasting effect on weight loss. Operation is not a solution but rather a lifelong involvement for the person. To loose a lot of weight means a big adjustment for both body and mind and the operated person may need support, advice, information and encouragement. Aim: The aim was to describe how a person, operated for obesity, can be supported in order to reach improved health pre- and postoperative. Method: A systematic literature study was made which resulted in 18 scientific articles that have been reviewed.

This paper aims to describe the variation and develop a method to control the production for the product Metropol Kaktus from the snuff developer Fiedler & Lundgren. We are going to use the requirements from the product specifications as limits of the expected quality when we present methods to control the process. One method attempts to control during the process and the other attempts to maximize the number of products with strived quality before the process starts. Metropol Kaktus is a product produced with high quality, the mean weight is 20,023 gram and this is very close to the weight, 20 gram, which is reported in the product specifications. The variation in weight variable is less than what is reported in the specifications and the minimum weight is over the limit set by Livsmedelsverket.

The purpose of this report is to come up with possible improvement suggestions to the distribution central at Götene Stål & Verktygs AB (GSV). GSV is a wholesale dealer located in Götene. The company doesn?t produce anything it self, it buys in products and sells them to customers.The distribution central at GSV is the place where the products comes in and gets ready to deliver.To come up with possible improvement suggestions we started with process mapping over the main process and the distribution centre process. The main process here is from the point where the customer gives GSV an order to the point where GSV deliver the order.Our result shows that the major problem in the distribution central at GSV is the big volume differences in the incoming goods.

Denna slutreflektion beskriver arbetet med att designa soundtracket till filmen Ont blod, en novellfilm som spelades in på Gotland hösten 2010 av Andersson/Wilén produktion. Vårt arbete har varit postproduktionen av allt ljud, inklusive musikkomponering. Syftet med arbetet var att testa och jämföra de två metoder av surroundmixning (direct/ambient och direct-sound all round) för film som Holman (2008) beskriver, för att sedan välja den som passar vår produktion bäst. Reflektionen är skriven i två delar. Den första delen handlar om produktionen i sin helhet och om projektplanen. Vi går sedan in på arbetsprocessen och beskriver utförligt varje del av arbetet inklusive tillämpningen av de två metoderna för surroundmixning.

In the last decades, high speed cutting has become an attractive technology in the wood industry. The possibility of reducing global costs in addiction with an increase in productivity, were the main reasons for the enlargement of the use of this technology. As usual, these advantages are accompanied by disadvantages that should be carefully analyzed. If on the one hand cutting forces are reduced with increasing cutting speeds, on the other hand, the centrifugal forces affecting the tool are higher. Exposed to such high loads, there is a considerable risk of tool failure that embeds hazards for both machine and workers.

AbstractThis report intends through a case study to investigate if lightweight concrete isappropriate as main material in the outer wall of a seven storey residential building.A technical design is carried out in accordance with the definitions and requirementsfor passive houses, given by FEBY?s1 ?Demand specification for passive houses?.A literature review is also carried out for a comparison between regular bolt wall andlight weight concrete wall, with a focus on the safety of moisture.The lightweight concrete block used in the report is as a celblock produced by thecompany H+H Sweden AB.The methods used have resulted in compliance with requirements andrecommendations from authorities. Calculations of energy, noise and moisture riskassessment has been carried out.The work has resulted in the conclusion that the lightweight concrete itself is notable to isolate in the extent necessary to obtain chosen U-value of 0,1 W/m2 ° C,without getting to thick. Therefore additional insulation is needed. There are fewrelevant reference objects built with only light weight concrete.

As trucks are getting more and more advanced, information about their weight has become a key factor for controlling them in a more fuel efficient and safe manner. Knowing the mass of a heavy duty vehicle in real time has been a difficult challenge for the truck manufacturers. With the processing power for electronic control units in trucks steadily increasing, more advanced algorithms for calculating the mass has been developed, but at the moment there still is a wish for better performance.Since there is a lack of good information regarding the external forces acting on the vehicle, forces that depends on the slope of the road, foundation of the road and the wind, the methods have to be able to disregard these. Such an approach, based on an indirect least square solution, has been evaluated in this thesis. The results have been promising and based on these a recommendation about further evaluation has been made..

The Sub-Saharan countries have for a long time struggled with poverty and conflicts which might have proven hostile for investors. The analysis aims to see if there is a significant correlation between foreign direct investments (FDI) and economic growth and which cultural and institutional factors seem to be significant in this correlation. Considered are also other variables and their influence that might explain what motivates and gives incentives for foreign direct investments (FDI) and are used in the construction of a regression analysis. This to see whether there is an effect on the economic growth in relations to FDI. The results show that FDI is of significance to the economic growth in the region and the study shows that corruption seems to be the most significant institutional factor in the correlation with effect on economic growth and the ability to attract FDI..

The county hospital of Dalarna has for the last couple of years carried through a process of digitalization. The result is that within the county it exists image plate systems from two different manufacturers. In an attempt to create a tool for dose optimization and dose surveillance the county of Dalarna would like to investigate if the exposure index from Agfa and Fuji is suitable as a dose indicator. An investigation of the exposure index, S, from Fuji has already been done. This thesis has been continuing the investigation by evaluating the stability of the exposure index, lgM, from Agfa.

Tomo Hugglink (TOMO Skog) is an innovation for harvest and transport of biofuels. The system consists of a truck, a chipping unit and crane mounted on a link and a wood chip trailer. The system works in such a way that the chipping unit is disconnected and placed on the site and wood chips are loaded directly into the wood chip trailer.The aim of this study was:- To examine the performance of the TOMO Hugglink system under different conditions such as the size, placement and quality of the pile.- To calculate the cost per raw ton for two vehicle combinations at different transport distances and to examine the effect of a reduction in set-up time and an increase in load weight.- To identify possible improvements with the TOMO Hugglink system.A time study was conducted within the thesis work to make it possible to determine production and time consumption. In the subsequent economic analysis the cost per tone at different transport distances was calculated for two different lorry concepts. Furthermore the effect of a reduction in set-up time and an increase in load weight was calculated.Under current conditions the utilization of the chipper is low and only 29 % of the total system time is occupied by chipping.

Control of a diesel engine equipped with Variable Geometry Turbine (VGT) and Exhaust Gas Recirculation (EGR) requires a multivariable control method. One problem is that the engine system is non-linear. Furthermore there are strong cross-connections between inputs and outputs and the inputs have alsoboundaries. To be able to manage these control problems, MPC has been used that is a multivariable method. The MPC-controller consists of an optimization problem and therefore MPC can find the optimum control signals in an easy way.
