Användandet av mobila enheter med appsystem och appars fackmannamässiga potential inom byggbranshen
Mobile devices such as tablets and smartphones are quite common in this day. The author of this thesis wanted to know how common these mobile devices are in the building industry and how they are used and what potential an app could have. The author thus conducted an investigation on this matter, mainly in the form of interviews.Answers given by the interviews were then used as a basis to survey the usage of mobile devices and the usage of different kinds of apps. An investigation of different apps with the potential to be used by professionals in the building industry has been carried through. Apps which manage such things as scanning documents, measuring distances and handle communication.

AbstractWrite the most important things first in text that will be read by a scanning web user. This paper is based upon theories about? how we read? what style in texts is? how texts should be written for web pagesReading from computer screens is about 25 percent slower than reading from paper. This because screens? flicker? have lower resolution than paperAll text with the purpose of being read from a screen should be adjusted to the reader?s physical condition.
Att spegla sin omvärld ? En exemplifierande fallstudie av Haninge kommuns biblioteksverksamhet
The purpose of this paper is to investigate in which aspects the public library is affected by its local community. This is re-searched by means of an exemplified case study of a Swedish public library in which we analyze governing documents and the library website with respect to environmental scanning and mar-keting of library services.The research questions are: How are the local community?s demands on the public li-brary being described in the governing document? How is the public library?s response to the demands of the local community being described in the operational plan? How are the demands of the local community, as shown in the governing document and the operational plan, re-flected in the marketing of library services on the library website?Our conclusions are that:The demands of the local community are described in a general fashion in the governing document, but there is a lack of concrete political guidelines.The public library's response to the demands of the local commu-nity is described to some length in the operational plan, but not with respect to economical factors.The demands of the local community are reflected to some length in the marketing of library services on the library website. Many of the overall themes that we identify in the governing document and the operational plan can be found in the marketing directed towards important target groups..
BIM : Förvaltning, inventering och användningsområden
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. .
Inverkan av olika joner och jonconcentrationer på porstorleksfördelningen i trämassa-fibrer
The basic ingredient of paper is the individual wood fibers. The property of the fibers depends on a variety of factors e.g., method of pulp production and processing. The final sheet quality depends in part on how the fibers interface between each other and therefore factors that affect the fiber size are of interest.The flexibility of the fibers depends in part on the pore water i.e., the fiber swelling. The sheet becomes less flexible at low water content which gives a loss in strength. Thus it becomes desirable to increase the water uptake.The experimental investigation described in this report consists of exposing the wood fibers to different ions and ionic strength and then measure the pore size by thermoporosimetry where a DSC (Differential Scanning Calorimeter) is used.
Forskning och museer : en kartläggning av fältet
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.
SEM/EDS-analyser av föremål påträffade i Birka : En jämförande studie
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.
3D-avatarskaparen
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.
Optimering av driftläggningar i Fortums nät
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.

Jämförelse av programvaror för konstruktion i råa punktmoln
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.
Flygburen laserskanning kopplat till skördarmätning för datainsamling till operativ planering :
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.
Det perioperativa samtalet-nyexaminerade operationssjuksköterskors uppfattningar
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.
Gymnasielärares informationssökning: En studie av samhällskunskapslärares informationssökning i yrkesrollen
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.
Utvärdering av olika metoder för framställning av höjdkurvor från laserskannade höjddata
Lantmäteriet (the Swedish mapping, cadastral and land registration authority) has been laser scanning Sweden since 2009. From the laser scanned data a digital elevation model (DEM) in grid format, with a resolution of 2 m, is produced. This DEM is called GSD-Höjddata, grid 2+ and from its data and the laser point cloud itself (in the form of a las-file) contour lines can be extracted. Lantmäteriet has not yet done this, but plans to update the contour lines in their cartographic products exist. If this is to be done in a satisfactory way an evaluation of different methods for it is needed.
