Fuktåterföring i roterande värmeväxlare

För att ha en chans att ändra trenden med ökande utsläpp av växthusgaser är internationella samarbeten nödvändiga. Därför har EU genom miljökvalitetsmålet Begränsad Miljöpåverkan satt krav på högsta tillåtna utsläpp av växthusgaser. Att sänka energianvändningen för upp- värmning är ett steg i att även sänka utsläpp av koldioxid, som är en av växthusgaserna. Sänkning av energianvändning kan göras på flera sätt, bl.a. genom att öka tjockleken på isoleringen eller återvinna värmen i frånluften. Men dessa åtgärder ska inte helt okritiskt göras.

Mode & identitet : - Att visa sin insida med utsidan

AbstractAim: The purpose of this thesis is to research how women think about fashion in relation to their self and to others. Can clothes be an expression of who we are who we want to be and how we look at others? What are the main characteristics in this type of communication and what kind of information can be distributed using this tool?Method/Material: InterviewsMain results: Clothes can work as a tool to show who we are and what we are, mainly on short term. We use clothes for different purposes, sometimes we what to be seen and really show who we are and what we stand for and sometimes we just what to go with the flow and not be seen at all. We will always have a physical need for clothes but it is also a natural and important part of our individual expression and our identity.Keywords: Fashion, Clothes, Identity, Lifestyle.

Implementation of a Simulated Annealing algorithm for Matlab

In this report we describe an adaptive simulated annealing method for sizing the devices in analog circuits. The motivation for use an adaptive simulated annealing method for analog circuit design are to increase the efficiency of the design circuit. To demonstrate the functionality and the performance of the approach, an operational transconductance amplifier is simulated. The circuit is modeled with symbolic equations that are derived automatically by a simulator..

Analys och planering av likviditet : En studie av kassaflödesanalyser och prognosers interna användbarhet inom ABB, Manpower, Gina Tricot och Västerås stad

Nyckelord: Kassaflödesanalys, kassaflöde, likviditetsplanering, likviditetsbudget, likviditetsprognos, likviditet och nyckeltal.Frågeställning: Hur och varför använder de fyra valda organisationerna kassaflödesanalyser och -prognoser internt?Vilka är skillnaderna i de fyra organisationernas sätt att ställa upp och använda sig av kassaflödesanalyserna och -prognoserna och beror skillnaderna på i vilken bransch de verkar?Syfte: Syftet med uppsatsen är att undersöka hur kassaflödesanalyser och -prognoser tillämpas praktiskt i de fyra stora organisationerna ABB, Västerås stad, Manpower och Gina Tricot för att identifiera om skillnader i uppförandet finns.Metod: Studien är av kvalitativ karaktär då fallstudierna av organisationerna gjordes genom intervjuer med representanter på respektive organisation. Totalt genomfördes elva intervjuer med tolv personer. Data till referensramen samlades in genom sekundära källor. Insamlad data och information analyserades där referensram och empiri sattes i relation till varandra.Slutsats: Brister i metoden för hur kassaflödesanalysen ska upprättas finns då den i praktiken inte används av de undersökta organisationerna internt.

This study aims to evaluate the value relevance of Piotroski?s (2000) nine fundamental signals. In order to do this, the signals are tested on the OMX Nordic Exchange Stockholm between the years 2003 and 2009. The hypotheses of the study are whether the signals are value relevant and if the value relevance has changed. To test this, a Chi-square test and a regression are used.

Identifiering av avgo?rande faktorer fo?r optimal intern bygglogistik : En fallstudie av tre byggarbetsplatser

Unlike the manufacturing industry, the construction industry is always in motion. Each new construction project brings new opportunities, and it requires a new plan, new organisation, and new suppliers. All construction projects are very different from each other and in terms of a logistical perspective, this is very weak as it makes it difficult to get a flow in the production and to make flawless routines. The way the external and internal logistics are managed, can effect the final product in the time taken to produce it, the quality of the product and the profit made from it. When internal logistics are handled poorly, it could result in materials not being at the right place at the right time, or information not going through to the right person.

Ledtidsreducering ur ett värdeflödes-perspektiv

This case study is performed within the production of Sherwin-Williams, Bellö. The purpose is to increase the understanding how a value stream can function more efficient, from a lead time perspective. With the analytical model that is build up on known theories, the purpose have been fulfilled. Mapping of value and non value time for four products thru their respectively process reveals wastes, which is, waiting, transport and movement, incorrect processing and set-up time that in it self create transport and movement. Thru identified wastes that causes loss in lead time suggestions of improvement has been proposed.

Time and architectural representations: the illusion of being eternal

Att beskriva en byggnad som tidlös är bland det finaste en kan säga. Några av världens mest uppskattade byggnader har beskriv- its som just det, tidlösa. Hur kommer det sig att en av den finaste komplimangen och erkännandet en byggnad kan få, egentligen är intetsägande? Tiden går ständigt och det finns ingenting någon kan göra för att ändra det. Människor, djur och även byggnader utvecklas och åldras.

To be able to find out we did a case study on a service producing IT-company. Two personal interviews were done with two of the managers. Our empirical research showed that the company used internal marketing on a daily basis.

Att reducera ledtiden i en produktion med hög variation och låg volym - En casestudie på Lab.gruppen

Due to increasing product availability and higher demands on fast deliveries, the competition between companies is growing. To be able to satisfy the customers? requests an efficient logistics system with short throughput time is required. By using tools associated with Lean production companies are able to make great improvements in their manufacturing systems and reduce lead times to satisfy customer demands.There are two classifications associated with manufacturing, high variety and low volume (HVLV) and low volume and high variety (LVHV). The general belief is that the concept of Lean production is difficult to implement in a production environment with high variety and low volume due to the concept being adapted to mass production.

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.
