Comparing Time and Accuracy of Building Information Modeling to On-Screen Takeoff for a Quantity Takeoff of a Conceptual EstimateAlder, Morgan A. 19 July 2006 (has links) (PDF)
Estimating is a critical aspect of every construction project. The most tedious component of an estimate is the quantity takeoff. Different tools are available to improve an estimator's productivity for a quantity takeoff. Faster quantity takeoffs enable estimator to bid more jobs. This study analyzed the time and accuracy of performing quantity takeoffs when using building information modeling (BIM) through a comparison study using Revit (BIM software) and On-Center's OST. In preparation for the study the researcher conducted a pilot study. Participants of the study were asked to perform a quantity takeoff using both Revit and OST. Their resulting data was then, analyzed comparing both the time and accuracy of each item taken off. The subjects' perspectives on the two different methods of performing takeoff are also included in the findings of this study. This study focused on a conceptual estimate takeoff for a small commercial building. The results of the study showed that, on average, those using BIM were able to perform the overall takeoff faster than those using OST while still maintaining equivalent accuracy. This study includes methods to improve productivity for quantity takeoff through an analysis of the takeoffs of counts, areas, and lengths. Findings of this study include methods, techniques, and cautions for performing a quantity takeoff using BIM.

A Plastic-Based Thick-Film Li-Ion Microbattery for Autonomous MicrosensorsLin, Qian 17 February 2006 (has links) (PDF)
This dissertation describes the development of a high-power, plastic-based, thick-film lithium-ion microbattery for use in a hybrid micropower system for autonomous microsensors. A composite porous electrode structure and a liquid state electrolyte were implemented in the microbatteries to achieve the high power capability and energy density. The use of single-walled carbon nanotubes (SWNTs) was found to significantly reduce the measured resistance of the cathodes that use LiAl0.14Mn1.86O4 as active materials, increase active material accessibility, and improve the cycling and power performance without the need of compression. Optimized uncompressed macro cathodes were capable of delivering power densities greater than 50 mW/cm2, adequate to meet the peak power needs of the targeted microsystems. The anodes used mesocarbon microbeads (MCMB) with multi-walled carbon nanotubes (MWNTs) and had significantly better power performance than the cathodes. The thick-film microbattery was successfully fabricated using techniques compatible with microelectronic fabrication processes. A Cyclic Olefin Copolymer (COC)-film was used as both the substrate and primary sealing materials, and patterned metal foils were used as the current collectors. A liquid-state electrolyte and Celgard separator films were used in the microbatteries. These microbatteries had electrode areas of c.a. 2 mm x 2 mm, and nominal capacities of 0.025-0.04 mAh/cell (0.63-1.0 mAh/cm2, corresponding to an energy density of ~6.3-10.1 J/cm2). These COC-based batteries were able to deliver constant currents up to 20 mA/cm2 (100% depth of discharge, corresponding to a power density of 56 mW/cm2 at 2.8 V) and pulse currents up to 40 mA/cm2 (corresponding to a power density of 110 mW/cm2). The high power capability, small size, and high energy density of these batteries should make them suitable for the hybrid micropower systems; and the flexible plastic substrate is also likely to afford some unique integration possibilities for autonomous microsystems. The mechanism by which the SWNTs improved the rate performance of composite cathodes was studied both experimentally and theoretically. It was concluded that the use of SWNT improved cathode performance by improving the electronic contacts to active material particles, which consequently improved the accessibility of these particles and improved the rate capability of the composite cathodes.

ScreenCrayons: Using Screen Captures for Annotation and ResearchTaufer, Trent Alan 16 December 2006 (has links) (PDF)
In a world full of digital information we should be able to easily collect, organize, annotate, and leverage information from many different sources. This should be easy to do and not interrupt our normal workflow. A system to support information collection and organization should be user-friendly and as unobtrusive as possible, while still allowing for flexible and intelligent annotation. It should also be able to leverage the inherent information content of a collection of annotated information. We present a system that will demonstrate how these ideas can come together to make information collection easier and more productive. The system facilitates collection, organization, and annotation of information using screen captures, and leverages the information content of the annotated collection to automatically summarize the information and find additional related information via searchable document repositories. ScreenCrayons is a system for collecting annotations on any type of document or visual information from any application. The basis for the system is a screen capture upon which the user can highlight the relevant portions of the image. The user can define any number of topics for organizing notes. Each topic is associated with a highlighting "crayon." In addition the user can supply annotations in digital ink or text. Algorithms are described that summarize captured images based on the highlight strokes so as to provide overviews of many annotations as well as being able to "zoom in" on particular information about a given note and the context of that note. Annotations the user makes on the screen captures are automatically associated with regions of text that are then used to formulate queries to a search engine. The results of these queries are filtered and ranked based on their similarity to the original annotations. The system then presents links to these documents to the user. We also describe an experiment that shows that the documents found by the annotation system are generally found to be more relevant to a user's topic than the users own queries using the search engine.

Föräldrars upplevelser kring barns användning av skärmmedierLandberg, Karin January 2022 (has links)
Syftet var att undersöka föräldrars upplevelser kring barns användning av skärmmedier. Med utgångspunkt i struktureringsteorin, cultural studies och identitetsteorin har uppsatsförfattaren undersökt frågor som berör föräldrar och barns relationer. Några frågor som har undersökts är om föräldrar använder begränsad skärmtid till barn, om föräldrar ansåg att skärmar skapade beteendeförändringar och konflikter och om barn mött faror på nätet. Undersökningen ville belysa föräldrars positiva och negativa bild av barns skärmanvändning. För att besvara frågorna användes en surveyundersökning som delades i föräldragrupper på Facebook där 323 föräldrar svarade. I analysen fick uppsatsförfattaren bland annat reda på att föräldrar engagerar sig i barns skärmmedia, föräldrar spelar spel, ser film och serier med barn och föräldrar upplever att barn införskaffar sig kunskap via media. Föräldrar läser ämnesrelaterad litteratur för barn om faror på nätet med förhoppning om att de ska våga berätta om de möter något obehagligt på nätet. Föräldrar märkte även av en del konflikter och beteendeförändringar hos barn. / The purpose was to investigate parents' experiences of childrens use of screen media. Based on structuring theory, cultural studies and identity theory, the essay author has investigated issues that affect parents and childrens relationships. Some questions that have been investigated are whether parents use limited screen time for children, whether parents considered that screens created behavioral changes and conflicts and whether children encountered dangers online. The survey wanted to shed light on parents' positive and negative image of children's screen use. To answer the questions, a survey was used that was divided into parent groups on Facebook where 323 parents answered. In the analysis, the essay author found out, among other things, that parents get involved in children's screen media, parents play games, watch movies and series with children and parents experience that child acquire knowledge via the media. Parents read subject-related literature for children about dangers online with the hope that they will dare to tell if they encounter something unpleasant online. Parents also noticed some conflicts and behavioral changes in children.
