ByggnadsInformationsModellering, BIM är ett komplext begrepp med varierande innebörd beroende på var i byggprocessen det används. Det finns ingen enkel definition av hur arbetet med BIM tillämpas och innefattar många aktiviteter. I rapporten har en litteraturstudie samt intervjufrågor legat till grund för resultat och slutsatser, dessa har riktats mot att ta reda på hur digital informationshantering anpassas till en byggnads förvaltningsskede och hur inventering av en befintlig byggnad kan utföras med dagens teknik. Genom att studera vad som tidigare skrivits inom ämnet samt med kontakter via personer som sysslar med konsultuppdrag eller förvaltningsadministration inom byggbranschen har en sammanställning av nuvarande tillämpningar kunnat visas. I grund och botten är BIM ett modernt arbetssätt som kan nyttjas av alla discipliner för att tillge information i ett projekt som även kan fortsätta att uppdateras vidare genom produktion, förvaltning, ombyggnader samt renovering, och slutligen rivning. Inventering av en äldre byggnad som saknar data kan återskapas med laserskannerteknik och ger en tillförlitlig datainsamling som sedan bearbetas i CAD-program. Forskning har skett för att försöka hitta ett sätt att lokalisera inbyggnadsmaterial utan att göra åverkan på byggnadskonstruktionen. .

Today every organization is committed to some kind of environmental scanning in order to get necessary knowledge of the world around them. The acquisition, organization and storage of information in combination with a strategic use, is today an important factor for a successful organisation in any sector of our society.In this Master thesis I have studied how an organisation such as The Confederation of Swedish Enterprise (Svenskt Näringsliv) handles its information resources. I have also looked at the flow of information within the organization. The Confederation of Swedish Enterprise is Sweden?s largest business federation representing 50 member organizations and 55 000 member companies.

The purpose of this paper was to identify the elements and the alloys that five objects found in Birka consist of and to examine whether there are any significant differences between the presumably imported and domestic objects. The material was analyzed using a scanning electron microscope (SEM) which was equipped with an energy dispersive X-ray spectrometer (EDS) in order to identify the elements that are present and the alloys that the objects are made of. Then the SEM results were compared with the results of previous analyzes that have been performed on finds from Birka in order to investigate how the objects differ in elemental composition and to find out if there are any significant differences between them. The results showed that the objects? content of the elements analyzed varies as the copper alloys the objects are made of.

The aim of this study was to gain a better understanding of resource schools 1 as a human services organization and institution, based on teachers and principals? perspectives. The purpose of resource schools is to provide the students tools and resources to enable them to return to the regular school within two years. The study also aims to examine more closely how this objective applies to the studied resource schools in the studied municipality, as well as highlighting the success factors and barriers that exist to achieve the goal. Previous studies show that this kind of differential practice tends to become a permanent solution.

This project report shows the work around a mockup to a three-dimensional avatar-making application. An avatar-making application is a computer-based software program in which it is possible to create your own personal virtual character. The possibility to use three-dimensional avatars can in the future be essential for adding extra personal information or characteristics to social communication over the internet or over mobile phones. The problem of transforming a physical form and reconstruct it to a virtual basis has been an important problem to solve for many companies and software developers in the, for instance, virtual worlds area. Methods and ideas over making this transformation is the key throughout this project.

Nowadays Wireless LAN is playing a more and more important role in network systems. After 1999, in which the IEEE organization published its Wireless Local Network standard 802.11[1], many people saw the advantages of the standard but also the lack of support for multimedia streaming. A lot of research work has been done on the proposed IEEE 802.11e standard draft during the past 4 years. It is supposed to be able to fully support Quality of Service. The final version will be published early in 2004.

Future emission legislation puts great emphasis on increasing the efficiency of the engine, thereby reducing fuel consumption. The tribological contact between cylinder liner and piston ring is where an great amount of energy is lost due to friction, and by reducing these losses an reduction in fuel consumption can be achieved.The aim of this thesis was to evaluate the tested piston ring coatings against a plasma sprayed cylinder liner and rank these combinations of materials for friction and wear resistance. The coatings that were tested was Cr + Al2O3, (Al,Cr)N, two types of CrN and WC / C.The experimental tests were performed with a so-called pin-plate, where used oil with addition of an acidic mixture of sulfuric and nitric acid to mimic the acidic condensate formed when exhausts recirculate, were added with a continuous flow. The results were then analyzed by weighing, studies by optical microscopy and scanning electron microscopy (SEM) and profile measurements.The results from each material combination were that the plasma coated cylinder liner wears too aggressively in order to yield a ranking of the piston ring coatings based on the parameters of friction and wear resistance. It is therefore proposed that an alternative coating on the cylinder liner should be developed, lacking the large abrasive wear on piston rings and that can withstand the corrosive environment resulting in engines equipped with EGR.

This bachelor thesis is about an ultrasonic sensor, implemented in a bubble chamber in Artis. The sensor consists of the piezoelectric sensor and an electronic control circuit. The control circuit consists of a programmable microprocessor, PIC18F2420 and a circuit, which sends the excitation signal to the piezoelectric sensor, and later receives the echo. This bachelor thesis consists also of a theoretical study, which examines different techniques of liquid level sensing in a chamber. The study discusses which factors are important in liquid level sensing and examine accepted methods.

Laser scanning is a method of surveying that has evolved rapidly in recentyears. The technique is based on a laser scanner set up, which can document a structureusing pulsed laser beams. Each time the laser hits a surface it is partly reflectedback to the scanner that stores the point. By using strategically placed targets, storedpoints from different scans can be merged into a point cloud. A point cloud is avisualization of the scanned object with a very high accuracy.

Executive summary This master thesis was originally based on a specific assignment given to the authors from ABB Full Service, a unit specializing in providing maintenance outsourcing: ?How can ABB Full Service expand its offering of providing fundamental maintenance by seamlessly incorporating the business concept with competencies and solutions from other ABB divisions?? The academic issue was developed throughout the thesis, resulting in the following formulation: ?From an organizational perspective; how can service providers bring continuous added value to intra-organizational outsourcing partnerships?? Many of the key findings of this thesis are reflected in the issue. The term intra-organizational outsourcing is a proposed addition to the terminology in the academic discourse on outsourcing. The definition of the term is: ? Where an organization outsources a business process interlinked with the physical operations, requiring the service provider to take over a preexisting unit and its employees.This is an accurate description of the form of outsourcing that ABB Full Service is engaged in.

The requirements for operative planning activities are increasing. The forest industry wants to gain better control over wood flow. A felling that is more market adjusted is desirable. However, this causes problems in the operative planning process because of the data collection methods used today. Data about timber assortments and data about the distribution of the tree diameter, etc., are often lacking. Airborne laser scanning is used to a greater extent than before for estimation of forest variables and should perhaps be used to the same extent in operative planning activities as well.

The perioperative nurse's primary responsibility is to care for the patient during the operation?s three phases; before, during and after. The communication between colleagues in the surgical department is increasing opportunities for safe care for the patient and a good dialogue with the patient can alleviate the concerns facing the unknown environment such as an operating theater. The pilot study was to investigate the surgical nurses' perceptions of conversations with the patient one year after graduation. To answer the pilot study's aim a qualitative interview study was chosen with a phenomenographic approach.

The aim of this thesis is to examine Social science teachers infor-mation seeking in their professional role.The focus in this study has been on what sources the teachers use for information seeking, examine and analyze their information practices and how they state their reasons for using different in-formation sources, and finally how these teachers experience con-ditions related to information seeking and how these conditions in-fluence their information seeking.This study is based on four semi structured qualitative interviews. The empirical material from the interviews has been compared to earlier relevant research and analyzed with a theoretical frame-work, which includes conceptions from a sociocultural perspec-tive, a matrix over different kinds of information sources devel-oped by Höglund och Persson and McKenzie?s model of infor-mation practices.The results of this study are:- These teachers use both formal and informal sources and external and internal sources. Digital sources are important and these have consequently been added to Höglund och Persson?s original matrix from 1985.- Information practices tend to overlap each other, for example ac-tive seeking (more specific and prepared information seeking) and active scanning (less specific), which are the two most common information practices among the teachers.
