The comprehensive purpose of this Master of Science thesis is to examine which fleetmanagement services for engineering vehicles, ?Fleetech? preferablyought to develop inorder to reach a broad market and meet the demands of contractors.Scanty explained, fleet management is the management of a company's vehicle fleet and theservices can include a range of functions such as driver management and fuel management. Inshort the thesis encompasses four sections:1.Survey of the general contractor industry: The survey has been preformed toevaluate the potential size of the market for fleet management services in the generalcontractor industry.2.Needs analysis: The needs analysis aim was to define what contractors tasks andgoals are, and to determine what functions they want and need from a system.3.The use of CAN and the technical premises: The prerequisite for developing asophisticated and generic system is that vehicle data can be accessed from the CANbuss.The use of CAN standards in construction equipment has therefore beenexamined.4.Specification: An explicit set of requirements have been set to be satisfied by a fuelmanagement service, based on CAN standard protocol J1939.Important conclusions: The use of CAN protocol standards are extensive and the prerequisitesfor developing elementary and CAN based services good. The services should be compatiblewith different manufacture?smachines.

The calcium homeostasis in the body is normally strict regulated to be kept within very narrow limits. This regulation is due to the action of parathyroid hormone (PTH) which is synthesized in the chief cells of the parathyroid glands. In different diseases, the calcium homeostasis is disturbed and this could either be due to a dysfunction of the parathyroid gland itself, or it could have a completely different explanation. To investigate disturbed calciumhomeostasis, ionized calcium and PTH can be analyzed from a blood sample. There are a lot of different assays to measure PTH in humans.

To achieve the Government's milestones for 2018, which means that 50 % of food waste shall be separated from household waste and undergo biological treatment (composting or anaerobic digestion).   Hultsfred, Högsby and Vimmerby are three adjacent municipalities of Kalmar, county Småland. During 2012 and 2013 analyzes were performed on their household waste to determine its composition. The household waste is currently collected in one fraction. The work, examines how much food waste the household waste contains. From the amount of food waste, the biogas potential is examined - how much food waste biogas generates and how much energy it corresponds to.   Food waste is broken down by microorganisms under anaerobic conditions (anaerobic digestion) in a biogas plant.

The higher status homestead called Kullen is located on top of a small hill just outside of Hova in V?stra G?taland. The house stands on a plateau surrounded by a stonewall. Aerial photos from the 1960?s shows what looks like a big parklike garden behind the house, with a gravel walk cutting through on the length of the garden up to the house.

Forest fertilization had its peak in the late 60´s, when almost 200 000 ha was fertilized annually. The silviculture of today has high demands for timber production at the same time as the demand for nature conservation increases. It means that it?s necessary to produce more volume in smaller areas in the future. The use of DGPS equipment has in modern forestry in Sweden become more and more common.

When drivers overnight in the truck lots of electric energy is consumed by heaters, fans, lights and other extra equipment. If the engine is not running, this energy is taken from the lead/acid batteries of the truck which then needs to be recharged during operating hours. The fact that the charge acceptance of the lead/acid batteries is dependent on the temperature makes it hard to fully recharge the batteries at lower temperatures. A negative charge balance can lead to starting problems within a few days use in cold climate.In this thesis work, the effects of different battery charging concept are evaluated on the most common Scania battery (175Ah). A battery model is implemented in Matlab and some simulations of charging are made.

This Master Thesis has been carried out in cooperation with Silva Sweden AB. A companywhich manufactures products like compasses, pedometers, headlamps, hiking poles and otherequipment for the out door life and navigation. The purpose of the project has been toassemble methods and models which support user involvement in Silva?s design process.Thus, to increase the number of products with purchasing power, enhance product quality aswell as increase foundation for new product ideas.The focus through out the project has been to assemble a pallet with methods for userinvolvement and from this select a few methods that will fit the company. The purpose of thepallet is to be accessible for the company during their work of change with the design processthat has been going on and will be in the future.

Haldex Barnes Hydraulics (HBH) is a company which produces hydraulic aggregates for use in forklifts, construction equipment, and trucks. The last two years the company has expanded. This has lead to an insufficient production of aggregates. Thus wishes HBH to increase their production without making to large investments.This report includes a now-state analysis of the problems and where they are. From this a further analysis of possible improvements are made.HBH works mainly with assembling and this is made manually.

 This report will describe a project between two students from Karlstad University and Markus Norström from Hovercraft solutions. The project aim was to develop a cabin for the hovercraft 380TD. The project was divided into two sub parts; one concerning the design of the cabin and one concerning the engineering. Throughout this rapport you can follow the engineering part of the project. The project has followed a systematic product development process resulting in optimized results for material selection and engineering solutions.

AbstractThe dependency of fossil fuels in the transport sector causes large emissions of carbondioxide. This problem can we reduce by using vehicle gas from digested solid manure and leftover of pasture. I have studied the potential for this in the county of Västernorrland. Thepurpose is to investigate how much vehicle gas that can be extracted.One central, large scale digestion and upgrade plant should be placed in Härnösand. Theamount of pasture and manure that is economical and practical available is enough to produce2,7-3,5 millions Nm3 vehicle gas.

The wastewater treatment plant at GE Healthcare's facility in Uppsala deployed a three step vacuum evaporator in 2007. The purpose of this was to pre-treat wastewater containing amines. The purpose of this thesis was to optimize thisprocess by reducing the amount of concentrate without releasing more nitrogen tothe environment and to examine if density could be used as a measurement of whenthe process should be ended.To create a foundation for optimization six test cycles were conducted with samples taken from all three steps. Both concentrate and condensate were tested as well as the incoming solution. Furthermore, the thesis has been expanded with a benchmarking part examining two different evaporators.

AbstractThis essay investigates what knowledge members of staff in day care centres for grown up people with disabilities have about Alternative and Augmentative Communication, AAC (in Swedish, Alterantiv och Kompletterande Kommunikation, AKK). Day care centres are working places for people with disabilities who do not have the possibility, caused of their disability, to work in ordinary works in the open market.To communicate with other people is a human right for all people even if you have a disability, even if you don?t have a spoken language or if you, because of your disability, have difficulties to understand a spoken language. When you don?t have a spoken language you need different ways to be able to communicate, make choices and take part in activities in the community.

När ett företag inför decentralisering medför det att det uppstår mer eller mindre självständiga enheter, som ofta handlar internt med varandra. Genom decentralisering vill företagen korta ner tiden för beslutsprocesser och ge ett större ekonomiskt ansvar för varje enhet, man vill med detta nå en effektivisering inom företaget. Problem som kan uppstå vid decentralisering är att samordning och kontroll av enheter försvåras. Dessa problem försöker företag lösa genom att införa ett internprissystem. Internprissystemet byggs på företagets specifika situation och dess syfte med internprissättningen.

Information and communication technologies (ICT) are constantly evolving in today's information society. The school uses ICT as a teaching tool and it begins to be included at the leisure-time in school by the educators.Aim of this study is to examine how educators describe their perceptions and experiences of using ICT in the leisure activities. The questions is about how the educators use ICT, what they believe children learn of ICT, and which advantages and disadvantages they see with ICT at leisure-time in school.Through a qualitative approach, I have had my questions answered by six trained educators, five of whom are recreational educators and one who is a preschool teacher. These have individually answered my interview questions as an interview took place over a phone call, while the others answered the same questions by e-mail. The interview questions were open-ended questions that were formulated so the educators could respond so freely and fulfilling as possible.The survey shows that teachers use ICT in multimodal approach at leisure-time in school, both in informing parents and in activities with the children.
