From Wikipedia, the free encyclopedia
A digital elevation model is a digital model or 3D representation of a terrain's surface created from terrain elevation data.
There is no common usage of the terms digital elevation model (DEM), digital terrain model (DTM) and digital surface model (D
surface morphology and roughness of the films was observed by field emission scanning electron microscopy (FE-SEM, Model: JSM-6701F) and atomic force microscopy (AFM, Digital Instrument, nanoscope III) operated at room temperature, respectively. The electrical properties of the films were determined using Hall measurement system (Van der Pauwconfiguration, Hilton, Australia) at room temperature.
Overview
The printer that is widely used is 2D printer. 2D printer is operated with papers and ink. It can print the letters, shapes and colored pictures on the paper. However, 3D printer can make 3D structure with ink like polymer. 3D printers make the product with not the top-down method but the bottom-up method. The most useful advantage of 3D printer is that it is the more useful device wh

Although the name of 'QR code' was difficult to remember at first, the recognition rate of 'QR Code' is increasing day by day. As smart phones have become popular globally, various marketings which are using it have appeared. One of the typical marketings is QR code marketing. If QR code which is also called 2D barcode is scanned, it simpl

The iPhone features an internal rechargeable battery. Like an iPod but unlike most other cell phones, the battery is not user-replaceable. The iPhone can be charged when connected to a computer for syncing across the included USB to dock connector cable, similar

RFID technology has been used by thousands of companies for a decade or more. The technology is not new, so why is it taking off now?
Until recently, the cost of RFID has limited its use. For many applications, such as tracking parts for just-in-time manufacturing, companies could justify the cost of tags—a dollar or more per tag—by the savings

“Developed a theoretical model to evaluate the overall heat transfer coefficient, considering both conduction through the solid and heat exchange from the solid surface to the gas.”
An accurate determination of the geometrical parameters of the foam was considering the difference in the pore size and the measured value res
