Individuell mätning av hushållsavfall i flerbostadshus : ?Ett incitament för minskad klimatpåverkan?
The electric vehicle market has potential to contribute to Sweden?s national goal to have a fossil fuel independent transport sector by 2030. However, the market answers to a lot of challenges making it difficult for the market to fully reach its potential. The volume of electric vehicles has seen a steady increase during the last year (2012), although many of these vehicles are mostly for PR purposes or bought by the public sector that wants to lead by example. Still, barriers in the form of high purchase costs, an anxiety for the limited battery capacity and the lack of standardisation are some of the problems that the market is struggling to solve.
Engångs- eller returtransportförpackningar i livsmedelsbutiker
Master thesis for Mechanical engineering, at the University of Lund. Incorporated in project Pondora.The purpose of this master thesis is to compare the existing one way packaging system with a proposed return crate system not yet available in Sweden. The comparison is focused on packaging handling in the grocery store.The purpose is also to investigate how operating return crate systems in Norway and Finland function, identify, the problems they have encountered and survey economic and technical aspects. The knowledge we hereby have acquired was subjectively evaluated in the thesis.The Swedish survey has a focus on meat and bread. The surveys in Finland and Norway contain all the products utilizing the studied return crate systems.We have surveyed how the handling of transport packages for meat & provision and bread is done in the store.
Designerrollen i en webbdesignprocess
This study investigates if, and in that case, how design theory is applied in practice in the web development field. Prior research has focused on methods used in the web development field. We wanted to study the designers role in a web design process by comparing existing designer roles with design theory literature. We did qualitative interviews with two practitioners at two different communication agencies in northern Sweden. Based on our qualitative data and literature review we have concluded that a designer has to devote a lot of energy on requirements engineering in order to develop a clear understanding of the design situation..
"The Never Ending Story" : Sårbarhet och kamp för överlevnad i Olofströms kommun
The world around us is shrinking and globalization and capitalism are processes affecting the world. Global trends, like outsourcing and relocation of firms to low-cost countries, have become more common. This creates a huge vulnerability in the municipalities that today are concentrated around a single large company. One of these is Olofström which today is one of the most vulnerable municipalities in Sweden and whose survival today lies in the hand of the company ?Volvo Cars Corporation?.
Automatiserad Verifiering av Grafiska Ritare och Tranformationsutvinning
En grafisk ritare i flygande system måste under dess utveckling verifieras för
att bekräfta att den fungerar. Då bilderna som ritas inte behöver vara
identiska mot referensbilder genererade av en fungerande ritare så ställer det
krav på verifieringsprocessen att kunna acceptera en viss grad av "fel". Att
automatisera den processen är i högsta grad intressant för att minska
kostnaden. Uppsatsen presenterar en samling lösningar på delproblem som kan
uppstå, däribland ett sätt att utvinna eventuell transformation mellan två
bilder..
Partnering för bättre samarbete men till vilket pris? : En studie av offentlig beställares argument till partnering

Industriell produktion av loggia - en studie om loggiarum som alternativ till inglasad balkong
AbstractIntense competition in the building industry has forced building companies to develop highly efficient and optimised building solutions. This project, with a loggia that works both as an extended living room and a glazed balcony offers a highly economic viable alternative to standard balconies. This alternative is likely to attract build master since the area of the loggia will be part of the apartment area, i.e. included in the area for rent..
Webbsäkerhet och vanliga brister - kunskapsläget bland utvecklare
This bachelor thesis looks at developers knowledge about web security both
regarding their own view on their knowledge and their actual knowledge about
vulnerabilities and how you mitigate against them. Web developers knowledge
regarding web security are becoming more and more important as more
applications and services moves to the web and more and more items become
connected to the internet. We are doing this by conducting a survey among
developers that are currently studying in the field or are working in the field
to get a grip on how the knowledge is regarding the most common security
concepts. What we saw was that the result varies between the different concepts
and many lack much of the knowledge in web security that is getting
increasingly more important to have..
Undersökning av modern reproduktionsteknik för
karosseridetaljer
En marknadsundersökning av förekommande metoder för digitalisering av karosseridetaljer. Olika skannertyper analyserades och en rekommendation av lämplig metod lämnades till uppdragsgivaren. Förutom punktantal beaktades även punktorintering, inskanningskostnad/tid, positioneringssystem och mätrymd. Uppdragsgivaren rekommenderades att använda en optisk skanner för projicering av fransar med ett optiskt spårningssystem. Då tillverkning skall ske i mycket små serier berördes även olika tillverkningsmetoder, som exempelvis hydroformning mot ett formverktyg av aluminium eller kompositcement.
Energieffektivisering på Skutskärs Bruk : Varvtalsstyrning till utvalda pumpenheter på Blekeri 4
In modern society in terms of economics and environmental impact, it is important to ensure that a company is as energy efficient as possible to reduce the amount of energy used. About 10 TWh of electricity used annually to pump drives in Swedish industry. Therefore, pumping system has great potential for energy savings.The objective of this report was to determine how much energy and money that can be saved with the insertion of variable speed drive to six pumps on Bleach plant 4 in Skutskär Mill. The work was performed with electrical measurements during one week, analysis of pump curves and the compilation of production data over a year.The results show that four of these six pumps were profitable and yielded an annual saving of 1172 MWh of electricity and 560 000 SEK. With an economic lifetime of 10 years and a discount rate of 6.8% the final result for the entire life-cycle savings became 3 355 000 SEK.
Lilla Spöket Laban
Detta är slutreflektionen över ett kandidatarbete gjort av Karl Tannergård och
Per Thulin. Arbetet har gått ut på att skapa en prototyp av en barnspel baserat
på Inger och Lasse Sandbergs böcker om Lilla Spöket Laban och hans familj.
Spelet är tvådimensionellt och vänder sig till barn i åldern fyra till sju år.
Det är skrivet i programmeringsspråket Python och använder
multimediabiblioteket pygame. Utvecklingen har skett i samarbete med
animationsstudion PennFilm AB..

Utvärdering av färdplaneringssystem
I denna rapport utvärderades olika färdplaneringssystem. Vid val av lämpligt färdplaneringssystem belystes några väsentliga områden. Avsikten var att hitta ett system som kunde hjälpa användaren att utföra sin flygverksamhet på ett kostnadseffektivt sätt och förenkla planeringsarbetet. Rapporten skulle vara en vägledning för bolag som står i begrepp att välja nytt färdplaneringssystem. I urvalsprocessen gjordes en marknadsundersökning för att välja de mest lämpliga systemen till utvärderingen.
Språkstöd i distanslaboratoriet på BTH
To study and laborate at distance, its necessary that the coursematerial is
accessible via internet.
Teaching at more languages than swedish bocomes more common,
why the information of courses needs to exist at several languages.
As teacher, you need a way to publish and edit material of a course. It also
has to be easy for the students to find the information. The distance
laboratory have developed an administrative websystem that handles programme,
courses and students, but misses the possibility for teachers to change content
at the webpages and publish new coursematerial on a way..
