Energibalansberäkning

Abstrakt -  As energy prices rise, energy-saving in buildings is becoming increasingly important. By applying different construction and installation technologies, to new buildings the energy consumption can be reduced effectively, compared to similar existing buildings. These technical measures are often an investment in the long term and will reduce energy costs significantly. The purpose of this report is to show how to reduce energy consumption in a small house. It is presented in this report that both building's technical saving arrangements (the sealing of a building) and an installation technical arrangement (changing from the F-system to the FTX-system) would reduce energy consumption in newly built detached houses, if compared with a similar existing house but without these technical measures. The report presents also detailed calculations showing how much energy an existing 2-storey house, built in the year 2007 in Eskilstuna, consumes and how much energy would be saved if these corrective measures were applied to a new building. It is also reported how much money would be saved each year over a 10 year period if the measures were applied. The results show that both solutions are a good investment in the reduction of energy consumption and hence the cost involved. Keywords: energy, heat energy, infiltration, FTX-system, free temperature effectively. .

Rekursiv greyboxidentifiering av drivsystem i industrirobot.

In modern industrial robots the components in the transmission contain nonlinearities. These nonlinearities need to be to estimated either for better control or to use the parameters for diagnosis of the system. There is a lot of work done within system identification and mainly within the field of iterative parameter estimation.This thesis considers recursive grey-box identification for a nonlinear model of the transmission in an industrial robot. The nonlinearities that are identified are friction, spring stiffnes, hysteresis and backlash. These nonlinearities are a part of the models that are presented in this thesis.

Kundlönsamhetsanalys som avbildande kalkyl och medskapande praktik: En fallstudie av Billerud

In recent years, customer profitability has become a focal point of academic discussions on business performance. However, researchers remain divided as to how evaluation of customers ought to be conducted, resulting in uncertainty of how accounting systems should be adapted to prevailing conditions. This paper aims to investigate the application of customer accounting techniques and the role they play in the organisational and commercial context in which they take place. In a case study of Billerud, a Swedish company providing materials and services for packaging solutions, the interplay between customer accounting techniques and customer relationship characteristics has been examined through the application of a theoretical framework developed by Lind and Strömsten. Particular emphasis has been put on deviations from the prescribed pattern of the framework.

Uppfyller BIM förväntningarna som arbetsmetod för broprojekt?

The purpose of this work is to design and construct a device able to measure the mechanical attrition of oxygen carrier particles. Those particles are used in chemical looping combustion and in the present situation there is a lack of knowledge in how the attrition process work and in which extension. To find already tested solutions trying to answering this problem a literature study wascarried out and the best solution found was the so called Grace-Davison Jet-Cup method. This method is supposed to emulate the attrition caused by a cyclone separator and its advantages are that it is possible to use small test amounts, 5-10 g, and a thirty minutes long test will be enough to acquire useable results. An device was designed based on the Jet-Cup method with some slight modifications.

Subjektiva och objektiva jämförelser mellan två benledningshållare, Softband och Adjoin

Background: Bone anchored hearing system is a surgically implantable system for treatment ofindividuals with hearing loss. The Softband is intended for patients who can benefit from a boneanchored hearing system but who are not yet suitable for implant surgery.Objective: The aim of this study was to investigate whether an adhesive bone conductor, Adjoin, canbe used as an alternative to Softband.Material and Method: Twenty adult subjects with normal hearing participated in the study.Measurement of functional gain and speech intelligibility was performed with Softband and Adjoinwhich then were compared. A questionnaire was answered by the participants after the measurementsthat treated their subjective experiences with each option.Results: The objective measurements yielded no overall difference between Softband and Adjoin forthe group studied. The subjective results showed differences in the perceived comfort as well as whichof the two bone conductors that would be preferred to use in everyday life, with Adjoin being thepreferred option. No difference was detected on participants perceived gain, sound quality and speechintelligibility.Conclusion: Based on the measured results, Adjoin seems to be a suitable alternative to Softband.However, there are questions about how Adjoin works with long-term use..

Energikartläggning av ett 1970-tals lägenhetshus på Skarpövägen i Nacka kommun : Simulering av energibesparande åtgärder i ?IDA Indoor Climate and Energy?

This study has been carried out in the spring of 2014 on behalf of PQR Consult AB in Stockholm. The aim of the study has been to analyse the energy usage of the building Skarpövägen 1 in order to explore the possibilites of saving energy by using appropriate equipment. These possible solutions have been simulated by using the programe IDA Indoor Climate and Energy, combined with a life cycle cost analysis. The laundry building, Skarövägen 23, has also been analysed due to its high amount of energy usage. The result of the energy analysis showed that the energy usage was much higher than the energy declaration.

Urban odling : möjligheter för framtiden

By exploring different forms of urban cultivation and looking into future gains of sustainability, I want to focus on unconventional and perhaps necessary ways of building, living and making a living. This will be made through study of literature on the topic.Urban cultivation could be anything from a pot of basil in the kitchen window to a city farm. The core of the concept is that the food is produced where it is eaten, in or in direct vicinity to the city and that it is produced ecologically. There will be many benefits, ecological, economical and social.The world is at a turning point right now where consumption patterns and the industry processed food are questioned and it is important that the things we consume are genuineand authentic. We want food that is locally and ecologically produced; food that we can trust.

Förbättring av väggfäste för flatscreens

The project was carried out in cooperation with the department of product development IOS at IKEA. The work included improvements of a new existing product that Ikea soon will release on the market, Observatör, a wall bracket for flat screens. The product is supposed to fulfil the needs within this market for IKEA. However, since Ikea was not satisfied with it, our work was to carry out the improvements that were specified in the beginning of the project. Another task in the project was to develop a side-product that is supposed to be used together with Obeservatör for storage of DVD/decoders.The project included labour as problem definition to final technical drawings and a prototype.

Etiska regler och konkurrensregler inom advokatyrket

Uppsatsen innehåller en studie av hur etiska regler, vilka framför allt återfinns inom advokatyrket, påverkar konkurrensen och de konflikter som uppstår mellan de svenska och europeiska konkurrensreglerna och dessa etiska regler. Mer specfikt identifieras vilka konkurrenshämmande effekter dessa regler medför, och vilka alternativ som finns för att kombinera etiska regler och konkurrensregler på ett sådant sätt att minsta möjliga skada uppstår för konsumenterna av advokattjänster. Resultatet av uppsatsen är att vissa etiska regler bör elimineras eller modifieras, eftersom de påverkar marknaden på ett negativt sätt utan att medföra motsvarande vinster annorstädes. The essay contains a studie on how ethical rules, here represented by the rules for the law profession, influence the competition. Furthermore are the conflicts that appear between the ethical rules and the Swedish and European competition rules identified and analysed.

Facket och de papperslösa arbetarna

In the beginning of 2002 a new kind of debate started inside the Swedish trade unions that also were published in the newspapers. The debate was about if the Swedish trade unionshould organize the undocumented workforce or not. In this thesis I will deal with this issue and also investigate what kind of solutions the trade unions in Sweden use on this newphenomenon, a phenomenon that recently have become a social and political problem during the last years. This is a new subject within political science and there is limited research made before. Because of that, this thesis will be empirical, inductive and exploring by its nature.

Lag om kassaregister : Motverkan av manipulation och snedvriden konkurrens

 This bachelor?s thesis purpose is to examine how library staff experiences the meeting with non-Swedish speaking users of public libraries, and how they solve different situations. Today there is not much research on this subject but we find these questions important to study because we think it is good to be aware of the situations that can arise and discuss how to solve any problems. To have a basis for this qualitative study we conducted group interviews with library staff, where they are asked about their experiences with non-Swedish speaking users. In the analysis the results of the interviews are compared to previous research and related to communication theory, which is the theoretical framework for this study.

Meaningful teaching in physical education ? A study of pupils opinions of the contents and teachers methods to activate and account inactive pupils.Nowadays people in society are getting more and more inactive, and we have during our practice at different schools, noticed that many pupils are uncalled for and inactive at the lessons in physical education. The purpose with the study is to see what pupils in the ninth grade thinks about the contents of the subject and what they want it to contain to make the teaching more meaningful. The study also looks in to different methods that teachers in physical education use to make the lesson feel meaningful for all the pupils and how they work to activate and account inactive pupils. To collect the information we chose to distribute questioners to pupils and do interviews with teachers.
