Utvärdering och åtgärdsförslag av energianvändning i kontorsbyggnad
AbstractEmbla 5 is an office building which has done a large improvement. The clients of this building has made an order of WSP and the student Anders Kempe to calculate the use of energy for the building, and after that result proposing further measures which can decrease the energy use of Embla 5.The ground for this report is when calculation of the present energy use of the building is stated. To make that information of a number of parameters such as envelope, the heating system and ventilation has been located and set in to the simulation program IDA ICE which calculate the energy use.To improve the energy use further this project has been concentrated to change the system of ventilation. Today the ventilation system is of the kind CAV (constant air volume) and the air flow is dimensioned for after recommendations from BBR and Arbetsmiljöverket in the office spaces. Consider that Embla 5 is an office building where the people only staying for 8-10 hours/day so was the ide to see how much energy saving if the air flow is reduced the time people not being in the building.
Arkeologi som kulturarvsförmedlare och kulturarvsturism ? ett möjligt samarbete?
For some time now, there has been a debate concerning the relationship between the Cultural Heritage of Sweden and the public. It is said that mediation has been, and still is a, one-waydialog between the two. As a result, people have found a new way to interact with our heritage, thru cultural tourism. This area has been blamed for commercializing our CulturalHeritage, but also ignoring the great problems concerning fragile monuments and sites, which can be destroyed by tourism. Is it possible to find a Solution regarding these problems, andcan these two areas benefit from each other?.
Konstruktion av säkerhetslagerför svänghjul
This thesis is the result of the investigation and Solution of a mechanicalproblem regarding flywheel malfunctions. A flywheel is, in short, a devicethat relies on a rotating object?s moment of inertia to store energy overshort time spans. This project is part of the development of a fourthflywheel prototype at the division for electricity at Uppsala university,which uses magnetic levitation to keep a hollow cylinder rotating at veryhigh speeds inside a vacuum chamber. Should the magnets fail however, orsome other error occur that leads to an uncontrolled state of rotation, thecylinder needs to be stabilized mechanically by a device usually referredto as ?back-up bearing?.
Utformningen av ett förstärkt skruvförband på en differentialväxel i bandvagnen BvS10 : Analys av olika förband med hjälp av CATIA och MATLAB
This is a thesis presents a differential gear which is found in a tracked vehicle called BvS10. The tracked vehicle is manufactured by BAE Systems Hägglunds AB in Örnsköldsvik, Sweden. The differential gear has a bolted house. The differential meets the requirement specifications, but the problem is that the bolts are sheared off because of the extreme torque that the differential is exposed to resist.Previous report on the differential show pictures of bolts which have been sheared off at the threads. This report is also includes three lists that explain seven different proposals which some are approved and some are not, and the report also presents the force, tensile, and shear stress.In a bolted connection there is both axial tension stress and radial shear stress, which can lead to wear out and broken bolts.

Integrering av ekodesign i produktutvecklingsprocessen hos Blå Station
Eco-design is all about improving products environmental performances throughout the products lifecycle by including the environmental aspect into the product development process. There are a large number of different tools that can be used for this, but there are several factors that can affect which one will be the best to use. Some tools for eco-design takes comprehensive studies and can only be performed by experts, while some tools can be used more time- and cost efficient and with basic knowledge. The choice of tool should be based on the company?s situation.This report describes the research of how the design and furniture company Blå Station could include a tool for eco-design in their product development process.
Återvinning av näringsämnen från hushållsspillvatten med omvänd osmos
Hammarby Sjöstad is a new district in Stockholm with high environmental standard. Stockholm Water Company evaluates a local wastewater treatment plant with cutting edge technology. The first step is an experimental treatment plant (Sjöstadsverket) with four parallel lines of treatment, each with a capacity to treat wastewater from 150 persons. Within the membrane technology subproject the possibility of using reverse osmosis (usually called RO) to regain nutrients is examined.Reverse osmosis separates the incoming water in a clean permeate and a concentrate that, as the name indicates, is a more concentrated version of the incoming water. Using this method in wastewater treatment, a Solution high in nutrients can be obtained without the use of chemical precipitation agent and with no production of sludge.
Solenergi : en lönsam investering för ett lantbruk?
A possible way to reduce pollution and slow down the process of global warming is to increase the usage of renewable energy sources. One of these renewable energy sources is solar power. With the aid of solar panels and solar cells the energy from the sun can be transformed into both heating and electricity. The requirement to use the sun in this fashion is a suitable surface, for example a big roof, an angle between 40-60 degrees and that the surface should be exposed to the south. Almost every farm meets these requirements.
Medling enligt föräldrabalken (FB) : En studie om domarnas syn på medling
This paper is based on a study seeking answers to questions about how the judges at district courts look at mediation as a way to deal with custody and visitation disputes between parents who do not live together. The questions posed in this study are: When is a mediator appointed? What result do judges expect to mediation? What do the judges say about how a mediator should work? What are the judge?s opinions about the lawyer?s role in these cases? Finally, how do the judges define the children?s needs and how do the judges check that the Solution is best for the child? The study also aims to compile theories of mediation, to create new knowledge and to possibly develop new research questions related to mediation. The study is a qualitative case study with law sociological and abductive approach. The interviewed judges all have a lot of experience in family law cases.
Strategic forest planning using AHP and TOPSIS in participatory environments : a case study conducted in Vilhelmina, Sweden
When a decision is to be made on what long term strategic forest management plan to use, consideration must often be taken to multiple objectives. Such decisions are very complex and a promising approach to handle them is by Multiple Criteria Decision Analyses (MCDA). The study is based on the problem that the MCDA that have been implemented into forest management planning have only had capacity to compare and evaluate a limited number of management plans; which means that there is a risk the most suitable plan is missed. The aim with this study was to test the applicability of combining the MCDA tools: the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) and the Analytic Hierarchy Process (AHP) for including consideration to multi-objectives into strategic forest management planning. The study was based on the process of creating and selecting a management plan, using Heureka PlanWise, suitable for all the major objectives found in the forest holdings of a municipality in northern Sweden.

Vätskekopplade värme- och kylåtervinningssystem Utveckling av ett verktyg för energiberäkningar
According to a decision of the European Commission, measures are to be taken to reduce the use of energy in the EU. The goal is to reduce it by 20 % compared to the current use. This shall be done to the year 2020 (European Commission, 2011). One industry that use large amounts of energy is the construction of buildings which account for almost a third of the energy use (Brogren, 2012). The major part of the energy that is used in the construction industry is not used when the buildings are built, but rather during the rest of their subsequent lifetime.
