The purpose of this study was to quantify the performance and assess the utility of two different types of scanners for radiochromic EBT film dosimetry: a commercial flatbed document scanner and a widely used radiographic film scanner. We evaluated the Epson Perfection V700 Photo flatbed scanner and the Vidar VXR Dosimetry Pro Advantage scanner as measurement devices for radiochromic EBT film. ...

The plane-strain bulge test is used to investigate the mechanical behavior of freestanding electroplated Cu thin films as a function of film thickness and microstructure. The stiffness of the films increases slightly with decreasing film thickness because of changes in the crystallographic texture and the elastic anisotropy of Cu. Experimental stiffness values agree well with values derived fro...

Thin Al2O3 films are grown and in situ doped with erbium by pulsed laser deposition in a single step process, by alternate ablation from Al2O3 and Er targets. The as-deposited films have an Er step dopant profile throughout the film thickness, whose concentration depends on the number of pulses at the Er target. The as-grown films are optically active, as evidenced by the photoluminescence spec...

Article history: Received 26 June 2016 Accepted 7 July 2016 Available online xxxx In the thin film transistors (TFTs) device research for foldable display, the degradation effect by the mechanical stress is crucial. Here, the crack position is critical for TFT reliability. However, it is difficult to characterize the crack position due to the random generation of the crack by mechanical stress....

In order to more accurately calculate the film stiffness of angular contact ball bearing, it is necessary to establish the film stiffness calculation model that is consistent with reality. The frictional heat exists in high-speed ball bearings, and can impact on oil film thickness and stiffness. The calculation model of film stiffness of an angular contact ball bearing taking account of the eff...

The global thin film transistor-liquid crystal display (TFT-LCD) manufacturers concentrate in Korea, Japan and Taiwan. In view of growing rapidly of demand in the world, the competition of TFT-LCD manufacturers has been a fierce phenomenon. The most important subject for every TFT-LCD manufacturer administrator is how to make the best disposition of resources and create more and more profits. T...

This paper presents a data hiding technique based on a new compression enhancement called Film Grain Technology. Film grain is a midfrequency noise-like pattern naturally appearing in imagery captured on film. The Film Grain Technology is a method for modeling and removing the film grain, thus enhancing the compression efficiency, and then using the model parameters to create synthetic film gra...

background radiography plays an important role in the detection of interproximal caries. objectives the aim of the present study was to determine diagnostic accuracy of chargecoupled devices (ccd), photo stimulable phosphor (psp) and film radiography in detecting non-cavitated caries. patients and methods seventy-two non-cavitated approximal surfaces of extracted human posterior teeth were radi...

the aim of this study is to compare the sensitometric properties of commonly used radiographic films processed with chemical solutions in different workload hospitals. the effect of different processing conditions on induced densities on radiologic films was investigated. two accessible double emulsions fuji and kodak films were exposed with 11-step wedge and processed with champion and cpac pr...
