Den mobila prefabriceringsfabriken : Ett nytt produktionskoncept
This is an investigation of a mobile prefabrication factory´s competitiveness and profitability which also will result in a suggestion for a design of the factory. The mobile prefabrication factory is an idea of a new concept for production which is meant to be used in the manufacture of slab. The main intention with this concept is that by using a fast established prefabrication factory to produce elements near the construction site, thus avoiding transport from the factory to the building site. This means not only an environmental and economic gain, but also that you can avoid risking damage the elements which often occur during transportation. The contractor is owner of the mobile prefabrication factory and can thus avoid long waiting times and cyclicality.

En kostnadsanalys av energieffektiva flerbostadshus
In Sweden the real estate sector accounts for 33 % of energy consumption and just below 10 % of the emission of carbon dioxide. As a consequence of the external pressure from climate change it?s in everybody?s interest to reduce the energy consumption and thus reduce the emission of carbon dioxide. An additional incentive to reduce the energy consumption is the substantial increase of the energy price since the deregulation of the electricity market in 1996.In this study the techniques that exist to build multi-storey residential buildings with high energy performance will be investigated. Further the study intends to investigate the optimal energy performance from a real estate economic perspective.In order to investigate the optimal energy performance a model has been created with the parameters investment cost, rental revenues, operation and Maintenance cost, discount rate and investment horizon.The result shows a relationship between a high investment cost and a high energy performance for newly constructed multi-storey residential buildings.
Parkeringsköp ? ett verktyg vid plangenomförande?
Few issues raise such an engagement as parking areas, both by the municipality, property- and car owners. For car owners, it is of great importance where to park his car. Parking is not simply about availability but also about safety, security and how it affects the urban environment.When the land will be utilized for building development, there are regulations in Chapter 8, § 9 PBL how parking will be provided. Property owners have an obligation to provide parking space and it shall be arranged in an equitable manner, on the site or near it, which gives an opportunity for shared parking facilities. The guidelines for parking that the municipality has adopted should be the starting point for the extent of that space for parking is required when a building permit review.The first thing you should look at, is if the property owner has ability to provide parking space at his own property, but this is not always the best solution in areas such as inner cities.
Framtidsoptimerad livscykeloch hantering av versioner : för Scanias Fleet Managementavdelning
In the haulage business customers are constantly requesting new features. Hence thedevelopment department must constantly update their system which ultimatelyresults in a variety of versions of the system. The large number of versions creates acomplexity which often reduces product quality and extends the developmentlifecycle time.The work on the following thesis has taken place at Scania?s Fleet Managementdepartment, which develops tools for hauliers to track their vehicle fleet in real time.The purpose of this thesis was to examine how Scania can handle an increasedamount of versions of the Fleet Management System which Scania expect will be seenin the future. The investigation was conducted by preparing a number of differentscenarios that formed the basis for a discussion of what these different scenarioswould mean for different parts of Scania?s business.
Lantbruket som energiproducent : tekniska, ekonomiska och miljömässiga förutsättningar för fjärrvärmeproduktion med lokalt skogsbränsle
A third party access to district heating networks has been proposed in Sweden, to increase the competition
on the district heating market. Such third party access could create opportunities for the agricultural sector
as an energy producer. This study describes the technical, economical and environmental prerequisites for a farmer cluster to build and run a heating plant, fueled with local wood fuel.
The heating plant in the described scenario is 8 MW and will supply a village of 1000 houses, and is fueled with wood chips exclusively. Supplying a heating plant with fuel puts high demands on the logistics, since there need to be a continuous flow of fuel. In the scenario, wood residues from felling and thinning is stored in stacks in the forest, and a few times a year chipped and transported to a storage area at the heating plant.
In the study, an estimation of the profitability has been made by estimating the cost of the investment,
personnel, operating and Maintenance costs and costs for the fuel and ash handling.
Automatic Trimmerhead
Automatic trimmerhead is an examination project for making an automatic trimmerhead for grass trimmers with the user and functionality in focus. Our perception is that a happy user is a user who can pick up his or her trimmer, use it and put it back to its place when the job is done. It should not be necessary to interrupt work and perform Maintenance on the machine just to make it work as promised.The project has been made in collaboration with the company Husqvarna, which is one of the biggest actors dealing with garden machinery on the market. Together we determined the project goal, ?To invent, construct and test a brand new concept for how an automatic trimmerhead can look and function?.At this day there are several different automatic trimmerheads on the market, both semi and fully automatic.

Utvärdering av viktmåttbaserad reglering av lokal- och regionnätens resursbehov
The Energy Market Inspectorate is implementing a new tariff regulation in Sweden. A small part of the new regulation concerns effectible operation costs and originally they where intended to be calculated using a modification of equivalent comparison standards, in Swedish Ekm. This thesis is intended to analyze if Fortums grid in Stockholm could be described correctly, using equivalent comparison standards. In Ekm every part of the distribution grid is designated a weighting in relation to 1 km 0.4kV over head line. These Ekm-measurements are intended to simplify comparison between different grid areas with different structure and geographical conditions.

Prosodisk förmåga hos svenska grundskolebarn med cochleaimplantat
Prosody can be characterized as the rhythm and the melody of speech. Prosodic features convey emotions, thoughts and geographic origins of each individual. Spoken language without prosody would be monotonous, without variations in loudness and rate. Children with cochlear implants perceive speech in a different way than children with normal hearing. Consequently the speech produced by a child with cochlear implants may sound different.The purpose of this study was to examine prosodic skills in Swedish children with cochlear implants and to compare them with the prosodic skills in Swedish children with normal hearing.
