Adaptiv stÀmning : En bedömning av acceptabilitet och tonkvalitetsuppfattning
This thesis presents an adaptive tuning system that can be described as a dynamic Just Intonation tuning system, being compatible with equally tempered instruments. The tuning system is called Hermode Tuning (HMT) and the tuning used as comparison for evaluation is the standardized western tuning, the equal tempered tuning. This study investigates preferences for these two musical tuning systems, depending on whether the tunings are presented on a piano or with woodwind instruments. A listening test was done with students at the Falun Conservatory of Music, including both a vertical listening (intervalls) and a horizontal listening (cadenses and musical compositions) of Hermode tuned musical material. Overall the results showed no significant preferences for either tuning system irrespectively of what instrument it was presented with.

AbstractIn the fall of 2003 a project was started in the Swedish building sector that is called BASTA (the building sectorsâ termination of especially harmful substances). The project is operated by the building companies NCC, Skanska, PEAB and JM, the Swedish Building Industry and the Swedish Environmental Institute IVL. The purpose of the project is to create a common environmental assessment system for the entire building industry and with the help of this system phase out the use of especially harmful properties from building products.In a large sense BASTA works like this; On the BASTA web site there is a database, to which a supplier can register the company and the companyâs products. Only those products with a substance content that fulfil the demands of the BASTA system, is to be registered. As it is the supplier himself that carries out the registration of the company and the companyâs products to the system, the BASTA-organisation annually controls that the companies that are registered in the database, fulfils BASTAâs demands.Since NCC is one of the companies that operates BASTA, BASTA is probably going to be the environmental assessment system that is recommended for the company in the future.

Ledarskapsutbildning ? till nytta eller nöje för Kommunstyrelsens ordförande? : En uppsats om betydelsen av ledarskapsutbildning
Many IT projects that have been developed in recent years are often considered to be unsuccessful. According to a study by Exido up to the 72% of all IT projects are considered to be failed. A failed IT projects means that the organizations that have ordered the new system may have higher costs or/and the system will not be ready in time. If costs are too high the new system might not be installed in the organization or if the system is not completed within the specified time frame the organization can become stagnant.In this paper we conduct an investigation of the failure of IT projects there we will examine where, in the systems development lifecycle four different phases, projects fail. We will conduct an empirical study of each phase, where we describe the key steps in the process; we will also investigate failed IT projects that are linked to the current phase.
Ett kommunikationssystem för fiberoptisk överföring av bilddata förvÀrvad av en miniatyriserad undervattensfarkost
This report describes the development and implementation of a system for transmitting digital information at high speeds from a miniaturized submersible developed by the Ă
ngström Space Technology Centre at Uppsala University. For instance, the vehicle shall transmit image data ? even stream live video - through an optical fibre to a monitor in a ground station. Hence, the system shall be used both to convert the image data to make it transmittable, and to recreate it at the receiver.The work includes a pre-study of the programming language and the technology used. A concept for the solution is presented together with main components later broken down into internal functions.
Implementering av ERP-system i offentlig sektor : Kritiska faktorer och mÄtt att beakta för framgÄng
ERP-system (Enterprise Resource Planning Systems) spelar en allt större roll för organisationer och att implementeringen av dem blir framgÄngsrika Àr av stor betydelse för ett företag. Det finns exempel dÀr en misslyckad implementeringsprocess medfört att hela företag försatts i konkurs.Följaktligen har flera studier gjorts gÀllande ERP-implementeringar. Ibland syftar artiklarna till att visa pÄ rekommenderade tillvÀgagÄngssÀtt genom att redogöra för implementeringens kritiska framgÄngsfaktorer ? de moment, aktiviteter eller liknande som genom studien identifierats som avgörande för en framgÄngsrik implementering. Majoriteten av studierna har berört organisationer i privat sektor.Författarna till denna uppsats ansÄg att det fanns starka argument för att dessa studiers resultat inte med nödvÀndighet Àr applicerbara pÄ organisationer i offentlig sektor, utan att de kritiska framgÄngsfaktorerna kan skilja sig Ät eller ha olika prioriteringsgrad i respektive sektor.
CMS och UX : tekniker för hur man utformar en god anvÀndarupplevelse
The purpouse of this study is to find out how and if a Content Managment System (CMS) can benefit from applied User Experience Design (UX). A work project has been executed where a client wanted the students to create a user friendly CMS for adding content to a global hotel review site. A prototype of a CMS was created based on literature studies about UX and CMS. The prototype of the user friendly CMS was then tested through user tests and interviews with key users. After input from the key users the prototype was changed until the users were satisfied with it..

LEED i Sverige och i byggprojektet Borgarfjord 3.
This thesis provides a good introduction to the American environmental certification system LEED, Leadership in Energy and Environmental Design, and trough compar-isons between Sweden and the United States an explanation to the systems design is given. The work is closely linked to a LEED Core & Shell project in Stockholm, Swe-den, where the goal is to reach the second highest rating in LEED - Gold.This thesis gives a broad description of the LEED system and a more profound study of the energy sector, Energy and Atmosphere. Here, for example, an analysis has been made of how the energy consumption of an imaginary building designed according to the requirements of the BBR (Swedish building code) performs in comparison to the Baseline building in LEED.The existing model of Borgarfjord 3, which served as a case study in this work, has al-so been modified to investigate the energy savings that could have been achieved by adding extra insulation to the building. A description of the problems, regarding how the Swedish district heating system (DES) is treated in LEED, is given as well as the suggested modifications. This is an issue that will be pursued during the process of shaping a new, international, version of LEED due to be launched 2012..
Konceptstudie av Waste Heat Recovery System pÄ Tunga Fordon
In today?s fast growing and closely connected society, a reliable and energy efficient transportation system is more than ever desirable. Nowadays the significant part of the transportation sector?s energy demand is supplied by fossil fuels.Improving energy efficiency in combustion engines will result in reduction of fuel consumption and CO2 emissions. A modern internal combustion engine has an efficiency of 30-45 %, where the most energy loss occurs as result of heat losses in the exhaust and cooling systems.

Miljöbyggnad, GULD vÀrt? : En undersökning av fastighetsÀgares erfarenheter och tankar kring ett nytt certifieringssystem
During the past few years an increased attention has been paid to environmental issues in the construction and property sector in Sweden. In order to simplify the work with these issues a Swedish environmental certification system for buildings called Miljöbyggnad has been developed. This thesis aims to investigate the opinion of a selected number of selected property owners of Miljöbyggnad. From that basis recommendations and actions for the future work with the system will be presented.The investigation has been conducted through personal interviews with five property owners. The main issues that the interviews have been based on are their purpose, experiences, perceived complications and future prospects in terms of certification using Miljöbyggnad.The system intends to be cost-effective, simple and to offer a relevant environmental assessment of buildings and the result from the report indicates that this is largely fulfilled.
