Ljudisolering i prefabricerade betongstommar. En fÀltmÀtning av luft- och stegljudsisolering.

Two elementary schools are now being built in GrÄbo (in the municipality of Lerum),Röselidsskolan and Ljungviksskolan, which are both designed with solar thermalcollectors for the schools domestic water heating. During the summer while thelargest amount of solar heat can be generated, the activity hence the domestic wateruse in the schools are heavily reduced. Both schools are connected to the local districtheating system which makes it possible to use the solar collectors to deliver heat tothe district heating.The purpose of this thesis is to evaluate the two systems mentioned above and todetermine which system is more suitable to apply on a school. The building whichconditions were used for this evaluation is Röselidsskolan.A solar heating plant of each system type was dimensioned from the expected andknown conditions of the building. The purpose with the dimensioning was to makethe solar plants replace the ordinary energy source as much as possible.

Implementering av mjukvarubaserat PLC-system för reglering av magnetiseringen av en synkrongenerator

In order to reduce the price for, and improve the performance of automatic control systems for magnetization of synchronus generators, the possibilities of using a PC based software PLC system, Programmable Logic Controller, has been investigated. The result is a system based on the CoDeSys software PLC with runtime environment from 3S-Software, communicating with external units via Modbus fieldbus. System price is reduced from ?5000 to ?2000 and system processing speed is reduced from 10 ms for a Siemens S7 PLC to 4 ms with the CoDeSys PLC system though unsolved problems with runtime seizure caused by improper settings in the PC BIOS..

Finns det risk för att Sverige gÄr in i en ny fastighets- och bankkris?

The purpose of this thesis is to investigate if there is a risk that Sweden will go in to crises at the house market and in the bank sector. The Swedish house prices have in the last years growth very high and quickly and are now over the development in the beginning of 1990. The method I use to investigate this is a multiple regression model. I follow a regression that both OECD and the Swedish Riksbank use. The difference between my analyse and theirs is that we use different periods..

HÀlsoresan : Patienter och patientperspektiv pÄ hÀlsohemmet FöllingegÄrden 1976?1990

In the 1970s and 1980s, Sweden held about 15-20 certified health resorts that wanted to improve peoples? health with vegetarian food and alternative medicine. This essay aims to explore the popularity of health resorts through a patient?s perspective. What did the patients look for at the resort, which they could not find in the official health care? A basis for the analysis is Bonnie Blair OÂŽConnor?s theory of Health Belief Systems.

Förstudie: Internt moln : En fallstudie för effektivare IT-administration

This is a report of a prestudy commissioned by a medium-sized Swedish company before an imminent major change in IT systems. The change aims to provide a simplified IT administration within the company through a cloud-based approach.The preliminary study provides an interpretation of the concept of cloud computing. It also covers a review of different models to use in order to achieve an internal cloud. Suggestions on how to proceed with the change process are also provided, and which models might be appropriate for the specific company..

Osmoreglera mera - Phaseolus vulgaris under torka. Genotypiska skillnader i osmoreglering som anpassning till torka hos vanlig b?na.

Torka ?r en av de st?rsta begr?nsande faktorerna f?r jordbruksproduktion globalt och med klimatf?r?ndringarna f?rv?ntas b?de f?rekomst och intensitet av torka ?ka. Detta utg?r ett v?xande hot mot livsmedelss?kerhet samtidigt som ?kade krav st?lls p? livsmedelsproduktionen i takt med jordens v?xande befolkning. Den vanliga b?nan (Phaseolus vulgaris) ?r en vidspridd n?ringsk?lla med m?nga olika varianter, som rankas som den mest konsumerade b?nan.

En generell processkartlÀggning av leveransplanering för biobrÀnsle i Sverige

The contribution of biofuels to the total consumption of energy in Sweden must increase to 49 % in order to meet the goals for the year 2020 set by the European Union. In order to do so, improved information systems are needed to support the business processes within delivery scheduling between customers and suppliers.Enterprise Architecture (EA) is a concept to enable the alignment of Business processes and Information Systems. EA is the framework for the architectures of business, information and applications. With a comprehensive view of the architectures, an Information System aligned with the Business processes can be enabled. The first step in the development of an Information System is documenting the business processes.The goal of this study is to clarify a generic sequence of activities performed within the delivery scheduling process and the information needed to perform the activities.Data for the study was collected through qualitative interviews, first through a meeting with the respondent and after that a following telephone interview with in total 5 suppliers and 6 customers of biofuels.

Gröna lösningar - en fallstudie av aktuell teknik för energieffektivitet för Skanska Sverige ab 

ur society is today in a phase of development in environmental and sustainable thinking. Alarming reports show changes in climate caused by our load and exhaust of resources. The energy usage contributes to a big part of it, by its emission of carbon dioxide. The built environment uses around 40 % of the total energy consumption in Sweden and requests to strongly reduce it are presented from both EU and national level.This thesis brings up the subject of green building with a focus on how we can create more energy efficient buildings in projects of new construction. Since the construction industry today often fails to pass on the knowledge between different projects, as a return of experiences, the construction company Skanska suggested the topic for this thesis.

Universell stolkonstruktion: Till HĂ€gglunds fordon

NÀr man pÄ BAE Systems HÀgglunds AB konstruerar en ny stol till ett fordon sÄ har man tidigare individanpassat stolarna utefter dess position. MÄlet med detta examensarbete var, istÀllet för att individanpassa en stol, konstruera en stol som gÄr att anvÀnda pÄ flera positioner i flera fordon. Ursprungstanken var att konstruera en stol som skulle fungera att anvÀndas i tre stycken HÀgglundsfordon, Armadillo, Bvs10 och Cv90, dÀr stolen skulle fungera pÄ förarplats i Cv90 och Bvs10 samt som chef- och skyttestol i Armadillo och Cv90. Eftersom HÀgglunds tillverkar fordon med inriktning mot försvarsindustrin medför det att stolarna sitter i fordon som idag anvÀnds i krigsdrabbade omrÄden vÀrlden över. Detta bidrar i sin tur att kraven pÄ stolarna blir mycket höga.

BAKTERIER SYNS INTE Sjuksk?terskors upplevelse av att v?rda patienter b?rande av multiresistenta bakterier. En kvalitativ intervjustudie

Bakgrund: Multiresistenta bakterier (MRB) ?r bakterier som har skapat resistens mot antibiotika. Antibiotikaresistens har blivit ett globalt problem som leder till att vissa infektioner blir allt sv?rare att behandla. Problemet har ocks? blivit alltmer omtalat, och det arbetas aktivt f?r att f?rhindra fortskridande utveckling.

Att utveckla medicintekniska informationssystem pÄ rÀtt sÀtt : En studie om regulatoriska aspekters pÄverkan pÄ systemutveckling och IT-innovation inom hÀlso- och sjukvÄrd

IT is often seen as a solution to many problems concerning effectiveness in organizations. Information systems within the healthcare sector is often viewed as medical devices rather than just systems or services. These medical devices are thoroughly regulated by laws, standards and certifications. In this study I participated in an innovative project that aimed to bring new life and use to the old fashioned patient journal by giving it a visual representation through the use of an avatar. I aimed to study the effects of regulators connected with the patient journal as a source of information for the innovative project.
