Ljudlandskapets Attribut: Metoder för att bättre förstå och beskriva ljudlandskap
In soundscape research, the field?s methods can be employed in combination with approaches involving sound quality attributes in order to create a deeper understanding of sound images and soundscapes and how these may be described and designed. The integration of four methods are outlined, two from the soundscape domain and two from the sound engineering domain. This study has shown that by combining these methods the understanding of both the entire soundscape and the specific sounds increase. The study also shows that when the methods are used, there is a qualitative change of the description and understanding of soundscapes and the concrete description becomes more elaborate..
Styrmekanismers funktion i relationsbyggande: En studie av ett relationsnätverk i verkstadsindustrin
The aim of this study has been to examine the role of control mechanisms when it comes to building relationships in a small business network. In order to reach this goal, we have performed a case study of a Swedish supplier of machines to the engineering industry, which acts as the exclusive representative of a foreign manufacturer on the Swedish market. Main results: A number of control mechanisms, both formal and informal, could be identified in the network. Their specific use, as well as relative importance differ between different actors in the network. In general, the importance of formal control mechanisms decreases as the relationship evolves over time and the importance of informal ones, mainly trust, increases in a corresponding manner..
Neutral bolagsskatt? : Analys om SOU 2014:40 skapar neutralitet mellan lånat och eget kapital
This paper examines the power producing dams along the Ume-river as an integral part of and a result from the urbanization process in Sweden during industrial capitalism. The aim of the paper is to contribute to the knowledge of the urbanization process in Sweden in general and of its traces along the Ume river in the county of Västerbotten in particular. The paper applies the theory of concentrated urbanization and extended urbanization put forward by Neil Brenner and Christian Schmid (2015) and argues that the building of power producing dams along the Ume-river is part of an extended urbanization process. This becomes particularly evident when examining the vast physical structures that is the dams, situated in an otherwise remote and sparsely populated area. These vast physical structures are also very well connected to a nation wide electric grid that has connections to bordering countries as well.
Kollisionsdetekteringssystem för autonom robot
Examensarbetet har utförts på företaget Husqvarna AB vid avdelning Concept & Features electric products (EN-NEP). Uppdraget var att utvärdera en alternativ kollisionsmetod till deras robotgräsklippare. Metoden som utvärderats går ut på att detektera kollision med hjälp av samplad data från en accelerometer samt samplad strömnivå från de bägge drivhjulens motorer.Den metod som används för att detektera kollision på nuvarande robotar fungerar väl men kräver att robotens kaross och chassi rör sig ifrån varandra för att krock skall detekteras. För att kunna reducera antalet komponenter och priset på roboten är andra metoder intressanta att utvärdera för uppdragsgivaren.En algoritm har designats i simulationsmiljö som sedan testats på ?riktigt? genom implementation i en Raspberry Pi som kommunicerar med robotgräsklipparen.
Kraftkabelförläggning i mark : - en studie av produktionsmetoder
The assignment given to us by NCC was to compose a degree project based on ground excavations for power cables. The aim of the study was to examine suitable excavation methods depending on different possible terrain conditions. The amount of previously written material within this subject is nearly non- existent and therefore there is a genuine interest by the NCC to receive a compilation of different production methods. The greater part of this study is based upon interviews with several companies active within this area of expertise. The technique of placing the electricity grid beneath ground for safety is today getting more and more common.
Standardiserad tillverkning av nätstationer
AbstractAbetong in Falkenberg manufactures, among other things, small prefabricated concrete buildings for housing various installations, such as electric transformers.The aim of this dissertation is to reduce the time needed to design such buildings, by way of finding a number of standardized buildings. Standardized in such a manner as to incorporate both the needs of the manufacturer (Abetong) and its customers.To analyze the needs of the parties the work has included a market survey and calculations on the strength of these buildings.One survey was a letter questionnaire to all of Abetong?s customers who have, in the past, ordered these types of building. The aim of the questionnaire was to establish how the customers want these buildings designed.Another survey conducted was an inventory of all of Abetong?s previous projects where these types of building were manufactured.
En ny förskola i Lerum
ABSTRACTThe discussions about energy use have increased year by year everywhere in the society, and so also in the healthcare sector. But what is actually energy use in a hospital facility, and what affects it?The typical way today to express the energy use is in kWh/m2. The problem with a key performance indicator that is expressed as energy use in relation to a specific area is that it does not take into account the activity in the building. Even though the activity to a very high extent affects the energy use.

PSQS ? Power Supply Quality Simulator
Kitron had wishes to be able to test and measure how disturbance affects their vehicle electronic units before they have been verified by SP Technical Research Institute of Sweden in Borås. This work started with the writing of a demand specification together with Kitron for a product PSQS, Power Supply Quality Simulator, which can generate some test pulses according to a standard for electronic units to Volvos vehicles. A design proposal was developed with the help the demand specification and was verified with the help of simulations. All electric schematics was designed with the guide of the design proposal. The pulses realized in the works of this thesis are those which Kitron experienced that they have a need to test in their own premises and which are possible to generate with the means available.
