The Kedertruss is the loadbearing part in the Keder weatherprotectionsystem and it has been analyzed concerning its loadbearing capacity. The Kedertruss is produced and manufactured by Wilhelm Layher GmbH & Co. KG and this report has been made for their Swedish division Layher AB.  The Kedertruss, designed in Germany according to German designcode, has been recalculated concerning Swedish conditions according to Eurocodes and a ongoing European standardization project. The two-dimensional program Winstatik Frame Analysis has been used for evaluation of load effects. Capacity has been calculated by hand-calculations and it has been verified that the Kedertruss in its larger spans isn?t able to withstand the loads.

The aim with this study is to prepare for a larger study, by gathering information about hunting enrichment, discuss which enrichment Parken Zoo in Eskilstuna have that are suitable to use in the larger study and report which observation methods that are used in other articles. In the larger study, the focus will lie on evaluation methods and measurable results. They have, during several years at Parken Zoo in Eskilstuna, developed different types of hunting enrichments for their carnivores, because hunting is a natural behavior that is hard to accommodate in captivity. The bigger project will integrate other zoos so that they can do a study on a larger group of animals, and because a lot of other studies in the same field only capture the results of few individuals. In this literature study you will read about the goals of enrichment, research that have been done on enrichment for felids and review several specific articles about hunting enrichment for felids..

Reverse logistics is getting more and more attention both from companies and the public. It is an area with the possibility for companies to do good in the eyes of the public. This work focus on the return system of a one-way handling material called the loading ledge. The loading ledge is developed by IKEA as a substitute for the EUR-pallet in transports from suppliers with a long distance and even flow and in transports from suppliers with short distance and uneven flow. The loading ledge is made out of 100 % recyclable plastic.The purpose of this work is to find the most efficient set-up for recycling of loading ledges within IKEA on a European level from a transport and handling point of view considering aspects like cost, environment, time and, from an administrative point of view, user-friendliness.Who will the participants of the set-up be, where will they be located, which transports are needed and which income and costs does the set-up generate, are questions that will be answered.

Municipal safety work is an issue frequently discussed. The new legislation about accident prevention obeys the Swedish municipality to present an action program for accident prevention. In Borlänge municipality there has been no sanctioned proposal for a program. This report presents the problems found and gives proposals for improvements in the future safety work. The guiding words should be unambiguousness, able to control and not too complicated.

During the last decade, the construction industry has focused on improving and optimising its production process. The construction industry is now facing larger changes regarding efficiency in their supply chain for the next decade. Many companies are now trying to optimise its supply chain together with its supplier. JM AB, which is one of the biggest construction companies in Sweden, is looking at different options to improve its own logistics together with their suppliers. One option is to use a terminal between JM and the suppliers to solve problems such as quality, custom service and inventory for the in production.

In 2013 a new emission standard for heavy trucks was introduced and hence a number of new parts was brought in to Scania CV AB. This created a need for modifications in the silencers flow. The flow is highly complex involving several suppliers, call off methods and different models of silencers. The aim for this project was to improve the existing silencers flow. The flow, from supplier to assembling, has therefore been mapped.

The report is a project in cooperation with the Swedish toy company Playsam. The assignment was to design a new toy to their range of products, a pull along toy in shape of a snail with a mechanical function. The research phase contains studies and analysis of the company, its identity, product range and its customers. The research phase includes all the information needed to complete the project. A number of concepts were presented for evaluation by the company.

Quality can be defined as the ability of a business to satisfy their customers? needs and expectations. Total Quality Management is defined as the way to prevent, appraise and improve the entire organization to increase the product quality. In order to systematically increase quality in an organization, there are different quality systems in use. One example is process management, which is to divide the activities of processes.

The thesis aims to compare differentpiping materials in heating systems interms of cost as well as to illustratethe impact of energy characteristics ofdifferent materials over its servicelife. The methods used for costcalculations regarding piping are alsoto be examined to highlight thedifferences between template basedcalculations and more carefully executedones. The work is delimited to discusspipes of steel, copper, plastics andcomposites. The aim is that the resultcan be compiled to illustrate the prosand cons of various materials whenevaluating investments.The main object of the survey is part ofa heating system in the office-block KVSommaren located in southern Stockholm.The configured piping system is designedwith the mentioned piping materials andis used to make up the data for flow andcost calculations. The differentmaterials are calculated in both aconventional manner with a supplementarycost for additional fittings and with amore accurate quantification of thecomponents.

This work is an experimental study where knock sensor placements are investigated using engine tests. The aim is to studythe quality of the signal from knock sensors and how the signal for engine control is affected at different sensor locations on Scanias, engine DC13. To find out at witch position on the engine youcan get a usable signal for engine control, the engine is running while the knock sensors with advanced measurement equipment is connected to the engine. Evaluation of signals from the knock sensors are made in the computer program Matlab. The program is producing a seriesof plots, from these plots it is visually possible to draw conclusions and find connections.

Kraven, som är framtagnamed spårbarhet i sjöoperativa förmågor, erfarenheter från den miljö ett luftburet system skaverka i ombord och systemexempel som visar vad som är möjligt att uppnå med dagenstekniknivå, presenteras som ett förslag till värderingskriterier och effektmått med tyngdpunktpå de krav som ställs på luftfartyget (UAV) i sig..

There are few legally protected gardens in Sweden, and those that are protected are mainly from the 17th and 18th centuries. All time periods have the same value and more modern gardens therefore needs to be protected. Evaluating parks is, however, complicated since it do not exist any methods. One environment from the 1960?s that has not been protected is Televerket in Farsta, Stockholm. The facility has been classified as worthy of preservation by Stockholm City Museum and has received the Kasper Salin Prize.

With background in the rapidly growing need to find solutions for sustainable energy production and the increasing interest for wind power, this report was written. With take-off point from the wind power plant Big Glenn, which has been built in the harbour of Gothenburg, a model of the adjacent power grid has been created in Simulink/SimPowerSystems. Parameters for the power grid and its components has been provided by Göteborg Energi Nät, that has also been the supplier of measurement data of produced power, the power need from loads in the vicinity, voltage levels, current values and also the variation of power factor at the wind power plant.The SimPowerSystems model has been used to perform simulations of power flow in the grid. These simulated values have then been compared to the measured values to verify the functionality of the model. Further, the model has been used to perform simulations of a grid fault, which causes a voltage drop.

The purpose with this report is to examine how the implemented energy efficiency measures on Bokelundskolan in Växjö have had impact on the energy use. The measures which have been implemented are, new ventilation system, new heating system, optimized adjustment of the heating system, new windows with U-value 1.2 and lower window height, insulation under windows and in the crawl space. The school's energy use before and after rebuilding has been calculated with the calculation program, Vip-Energy 1.5.5.Calculations of energy use for the school with windows on U-value, 0.9 and 0.7 have also been done. The replacement of windows has been studied from a cost perspective. The conclusion is that the exchange of heat and ventilation system was the biggest contributor to reduced energy use on Bokelundskolan.

A pilot-study was used to investigate, types of assistance, assessed needs, outcomes and effects of special-needs assistance given to a subsample of compulsory school pupils in an effort to develop an evaluation strategy for identifying educational impacts of specific special-needs inputs.  Preliminary results indicate a tendency for postive outcomes for most pupils in the pilot group (n = 11) but also that many pupils have residual difficulties.  Pupils with residual difficulties mostly required special education asssitance with Maths, English or Swedish.  More pupils also needed support with behavioral difficulties.  More research and an expanding knowledge base is required in order to effectively evaluate outcomes of teacher support.  Schools need help in devising different methods of assistance and particularly for pupils with behavioral difficulties..
