This Master thesis has been carried out at Scania CV AB in Södertälje, in collaboration withKTH, The Royal Institute of Technology, Stockholm. The focus of this Master thesis isSetBased Concurrent Engineering(SBCE), with the purpose of answering the questions: what isSBCE, how does it work, and for what purposes is it applied.It was early established thatSBCE is often included as a part of Lean product development,which in its turn is often related to Toyota?s way of working. TheSBCE method includesworking with multiple solutions in parallel, eliminating weak alternatives throughout thewhole process. In opposite to a conventional product development process, where it iscommon one at an early stage tries to identify and choose the most promising alternative.Despite the appearance ofSBCE as a resource consuming method, figures from Toyotaindicates the opposite, thatSBCE is in fact a very effective way of working compared to othermore traditional methods.The process of this Master thesis was divided into three phases.

Wastewater handling of private sewage systems has become an all increasing matter. In Stockholm region the 90 000 private sewage systems contribute with larger phosphorus flows to the Baltic Sea than the two biggest sewage plants in the area, Henriksdal and Käppala, contribute together, even though these two plants purify wastewater from more than one million inhabitants. When summer house areas turn into areas for permanent living ? transition areas ? the load on the existing systems increases, systems that already often are unsatisfying. In those areas it is not clear what the best system choice is; On-site systems for single households; Local collective systems or Connection to central systems.

sustainable development by reducing the energy use by EU:s directive of energy efficiency and the UN Convention. The second purpose is to present the technical solutions regarding ventilation and heating system that is being used in passive houses. This was done using 8 passive houses, 4 germany and 4 swedish passive houses. Even the international and Swedish system requirements for passive houses have been addressed in this project. The goal was also to explain how and why the mechanical system in passive houses has developed to the technology used today.

High technology companies in Sweden spend a huge amount of money on research and product development in proportion to what they get back in earnings from their inventions. Product development has traditionally been regarded as much more important than business development. This thesis aims to point out the critical factors behind successful business development processes for high technology companies. We have chosen to make a case study of Hexagon, a highly successful and innovative company within the measurement technology business. Internal and external actors that are important for business development have been identified and interviewed in order to understand how ideas are developed and executed.

Webbaserad programuthyrning innebär, till skillnad från traditionell försäljning och implementering av informationssystem, att kunder erbjuds hyra systems funktionalitet över Internet. Denna modell anses av många ha stor framtidspotential, men skeptiker ifrågasätter konceptets hållbarhet och vi upplevde kvalitetsrelaterade problem i samband med driftsättning av ett system som användes över Internet under förhållanden som ur ett tekniskt perspektiv liknar programuthyrning. Syftet med denna uppsats är att undersöka om tekniska förutsättningar, vad gäller prestanda, pålitlighet och säkerhet, är goda för att bedriva webbaserad programuthyrning och om dessa förbättrats under de senaste åren. För att besvara undersökningsfrågan genomfördes prövning av fem hypoteser med anknytning till problemområdet. Empiriskt underlag togs fram genom mjukvarutester genomförda 1999 och 2003 samt en enkätundersökning ställd till det testade systemets användare.

Earlier studies of musculoskeletal problems with milkers working in milking parlour operators have shown that it is a physically demanding occupation. The extremities that are most exposed are neck, shoulders, hands and wrists. Those systems that have been studied in present cases are fishbone and some tandem barns. There have been changes in the working environment during the past ten years. The mechanisation has been developed for the better with automatically removers of the milking units and vertically adjustable floors in almost every daily milking barn. In other hand the milk production are more industrialised and more related to stress today.

The company System Andersson is developing systems for controlling materials and production in industries. They want to add a new service, where parts of those systems are accessible through cell phones.In this paper we are investigating which technology are best suited for this kind of application. And then we describe how we are developing a prototype fort this application, based upon that technology. After investigating technologies such as Java ME, Microsoft Silverlight, and web applications we settled upon building the system as a web application, customized for a mobile environment.To build a web page which is readable by many different cell phones we use the markup-languages which are developed for cell phones. We put much effort in reading about the standards and recommendations for the mobile web, produced by the organizations W3C and OMA.

The industrialized timber housing process is capable nowadays to build multi-storeyhouses since fairly new changes in the Swedish regulations where made after theadmission of the European Union in 1994.The industrialized process moves parts of the construction process into a highlyeffective factory where 3D-volumes of the building are prefabricated beforetransportation to the building site for assemble.The assembly process is relatively effective compared to the completion of thebuilding service system and this is therefore the main focus in this thesis. This thesisattends problems with completion of the building service system, and thereforedemarcates from other aspects, such as technical and economic aspects, of thebuilding service system.The degree of completion of the flats differs from completion of the connectivepassages, for example hallways, in a way that suggests a need for further investigation.This thesis includes analysis of the possibilities to increase the prefabricatedconnective passages, to the extent of containing building service systems.An increase of the prefabrication of the building service system has a greatdevelopment potential, even though some restraining factors need to be solvedbefore implementation.This thesis was made in collaboration with two of Sweden?s leading companies on themarket of multi-storey industrialized timber housing, Moelven ByggModul AB andLindbäcks Bygg AB..

ABSTRACTThis pilot study examines the knowledge about tree root systems amongst five treeplanting professionals. The aim is to find out the professionals? collective knowledge ofthe nature of root systems of various trees used in green areas. Furthermore; to explorehow the professionals adapt landscaped green areas to the tree root properties in asustainable manner. Questions: Which tree species have special root properties toconsider and how do the professionals utilize this knowledge? And: How do theprofessionals in general adjust planting according to the root systems of trees in areas tocreate sustainable green environments?Interviews with the professionals were performed.

There exist several known methods for calculation of radio coverage for ground-based systems. As far as we know there are no equivalent methods for the case of flying platforms when the altitudes and speeds are significantly different to those of ground-based systems. This thesis describes the theoretical concepts behind calculations of radio coverage for flying platforms. An investigation is made to sort out what is important and possible to employ in a model for simulations. A method is described and implemented in a program for evaluation of flying radio systems.

Sustainable urban development is a concept that has become increasingly important as the urbanization continues and more and more challenges are focused to the cities.  The Swedish government and authorities regulates and sets goals for how a sustainable urban development is to be achieved. These laws and goals are vaguely defined, which leads to disputes between the actors about how the term should be interpreted. By examining Västermalms Strand, an urban development project in Stockholm, this study strives to describe how involved actors interpret the concept of sustainable urban development and what the consequences of this are for urban development in Stockholm from an ecological, social and economic perspective. A case study has been carried out where a document study and interviews have been conducted. The interviews were conducted with four key actors from the private and public sector.

Vi lever idag i ett informationssamhälle där mängden information och informationssystem tenderar att öka med tiden. Företag strävar hela tiden efter en ökad kontroll av sina informationssystem och därför har begreppet ?IT-konsolideringar? kommit att bli ett populärt koncept. En konsolidering syftar till att förstärka ett företags IT-miljö och påverkar ofta de anställda. Därför är det intressant att studera hur utvecklare arbetar med beställare och slutanvändare vid en IT-konsolidering.

AbstractMy purpose with this essey is to study how they work in preschool whir language- stimulation. I will try a way to work with this trough intervjus whit teacher at preschool. My main questions are: Way dose teachers use language- stimulation? How dose teachers use language- stimulation when it comes to there way of working and methods? Do the teachers think that language- stimulation help the childrens development?To answer these questions I interviewed 6 teachers I central Sweden and used this as data. I have written about language, language- development in a biologik and theoretical aspect, teachers plan, language- stimulation, playing by language sounds and TRAS (early registration of language development) in my literary review.My result shows that working whit language- stimulation helps children in there language- development, it also develops there self-image and identity.

The aim of this essay is to examine three separate Swedish public libraries and their respective websites on the grounds of the usability sciences. I firstly had to summarize the main properties of the usability-field in order to gain an extended knowledge of its purposes and possible usage for today?s library systems. I was then able to apply the extended knowledge in the examination of the three library websites and the purpose of determining whether or not they were designed according to the standards set by the usability-sciences.Usability is a rather new science that deals with the dissection and examination of computer-based systems, in order to find the key components that make systems user-friendlier. With user needs being the main focus of its research, usability tries to meet all the different needs of the modern user and construct systems that are less system-centered and more user-centered.
