Det finns stor potential i byggbranschen att förbättra produktionsprocessen på en arbetsplats med hjälp av nya planerings- och modelleringsverktyg. En produktionsteknologi som är särskilt intressant att studera är det platsgjutna betongbyggandet. Här utförs många olika, men sammanhängande, moment tätt på varandra och processen styr mycket av andra processer som följer efter detta skede. Det är därför viktigt att kunna planera och kontrollera byggandet med platsgjuten betong med enkla och effektiva planeringsverktyg. En relativt ny modelleringsteknik som har stor potential att förbättra produktionsprocessen är 4D CAD.

This report deals with activities that from a CSR perspective are considered to create a shared value for a medium-sized construction company in Sweden. The CSR definition used in the report is the European Commission?s since it reflects the valuecreating aspects of CSR, in contrast to the traditional philanthropic aspect of CSR.Companies in the building construction industry have difficulties identifying activities that create value in society and in the company. The aim with the project is to, from a CSR perspective, identify and evaluate value creating activities in a building construction company. The activities will be evaluated with respect to competitiveness and how they can be implemented into an organization.

För att Swepart Transmission AB ska fortsätta att hålla en hög standard på produkter som levereras till kunder, ska monteringslinan för Power Take-Off säkras. Budgeten som är avsatt till att kvalitetssäkra monteringslinan är 500 000 kr. Pick-to-Light och Pick-to-Voice är system som kan användas för att kvalitetssäkra monteringen av Power Take-Off. Systemen jämfördes med systemet med monteringskort som används i nuläget. Det mest lämpliga att införa har visat sig vara Pick-to-Light.I samband med införandet av detta system måste utredningar göras för vilka komponenter som behöver sensorer och vilka som kan säkras på andra sätt.

Speech Transmission Index (STI) är både en metod för att mäta taltydlighet och en skala som beskriver taltydlighet. Metoden presenterades av H. Steeneken och T. Houtgast 1985 och har därefter fått många användningsområden. STI beräknas utifrån modulationsindex, där modulationsindex är förändringen av modulation genom ett system.

Oxytocin is a hormone which plays a crucial role in many reproductive and behavioural functions. It affects many organs and the classical peripheral targets are the mammary glands during lactation and uterus during labour. Oxytocin receptors have recently been described in a variety of normal tissues and primary cell cultures, but also in neoplastic tissues and established neoplastic cell lines, as breast cancer cell lines. The signalling pathways and biological effects of the oxytocin/oxytocin receptor system seem to depend on species, type of tissue, physiological versus neoplastic state and receptor location within the cell membrane.The aim of this project was to find out if the cell proliferation in the canine mammary carcinoma cell line CMT-U27 was affected upon stimulation of oxytocin, and to investigate the presence of oxytocin receptors in these cells. The cell proliferation was examined by using an ELISA-kit, where the absorbance measured is relative to the amount of living cells.

This paper is about basic set theory and cardinalities for infinite sets. One of the results are that the line R and the plane R2 contains exactly the same number of points. Because of that the set theory is described with a formal language this the paper has an appendix about formal languages..

Improved wireless datacommunication with the forest machines might be the next big step in the logging process. The use for wireless communicationsystems within the forestry is among other things to report the production from the forest machines, to supply the machine opera-tors with the right information and for safety. CDMA2000/ 450 is a third generation mobilecommunicationsystem which could replace the old NMT- 450 and for comparatively low costs. The reason for the low costs is that you only have to use the old NMT- 450 masts and supply them with new equipment. In the test of CDMA2000/450, that has taken place in northern Uppland, two kind of files have been sent.

During the period called Little Ice Age (1400 ~ 1900) the climate of northern Europe was in an annual year-basis overall colder than it was before and after that period. The numbers of short, cold and rainy summers and long, bitter-cold winters where often repetitive under the approximately 500-years the period lasted. In Scandinavia, the coldest time during this period is estimated to have started around the end of the 16th century and lasted to the beginning of the 18th century. Trees growing at the tree-line are limited by temperature for their annual growth and hence showing differences of growth during changes in the climate,  a method called dendroclimatology. The variations of growth can be read in the tree-rings either by analyze the width of the ring or by look into the density of the wood and is used to reconstruct past climates.

Nine out of ten larger companies have an intranet today which is supposed to improve the communication withinthe company and save money. A great part of these intranets were established in the beginning of the 1990?swithout giving any thought to the users and their needs. How does the communication inside the corporationslook like when the intranets that are supposed to be the source for every information request, aren?t usable? Whatother sources do the users use and how much?The aim of this master thesis is to examine information source selection at a specific company.

The purpose of this study is to understand the factors that are affecting students at the Technology and Electricity- and energy programs in their choice of studies and vocation. The study is a comparative case study and quantitative method has been used in the form of questionnaires. The result shows that students do not like to be affected by another person but believes that they themselves have made their choice. Interest turns out to be the biggest influence factor of choice for both students at the Technology and Electricity- and energy program. For Electricity- and energy students have also access to work had some impact.The parents' education level was higher for Technician students and their parents worked with occupations requiring university degrees.

The purpose of this study is to improve the understanding of the dynamics behind Chinese-Western buyer-supplier relationships. The study takes on a partially inductive approach by commencing with exploratory in-depth interviews. The main body of the study consists of a cross-sectional survey. Data has been collected through an on-line questionnaire. The theoretical review consists of industrial relationships with specific accounts on the role of adaptation, trust and commitment; a stream of literature in cross-cultural relationships deriving from Hofstede?s culturalist legacy with specific reference to Chinese-Western relationships, including studies on relationship bonding, and the role of guanxi.

This report is the result of an investigation of the possibility to use RFID-technology in a producing company. The investigation is focused on a flow between the company?s producing subsidiary company in Lithuania and its main facility in Sweden.RFID is the abbreviation for radiofrequency identification. The RFID-technology forms the base of a system with wireless information transmission between an object to which a transponder, also called tag, has been attached and a reader. The information is transmitted by radio waves and the system is equipped with software that can digitalise the radio waves.

This thesis describes how a cost reduction project was done on the Packsize ondemand packing machine EM7. The cost reduction was achieved by making minorredesigns of the EM7.The project began by studying the EM7´s structure and function by working on itsassembly line. A short literature study on the subject Design for Manufacturing wasalso done.By working on the assembly line and by speaking with staff from production anddevelopment departments, a number of ideas for reducing manufacturing costs arose.Estimations of the potential cost reduction size for each proposal were done incollaboration with vendors and the purchasing department. Based on the size of the cost reduction, technical risk, impact on the assembly lineand the development time the various proposals were ranked. The two highestranked proposals were selected for further development towards finished solutions.One of the ideas that were selected to develop in to a finished solution meant thatsome of the pneumatic valves were replaced with others.
