A bstract We propose the three-dimensional counterpart for Jackiw-Teitelboim gravity coupled with CFT 2 bath based on partial reduction. The is classical AdS a defect brane which has small fluctuation in transverse direction. derive full action by considering as dilaton field. demonstrate that fine-grained entropy computed from island formula precisely agrees extremal surface. Our construction ...
Understanding the stability and reactivity of iron sulfide phases is key to developing predictive capabilities for assessing their corrosion and catalytic activity. The differences between the free surface and the bulk interior of such phases are of particular importance in this context. Here, we employ density functional theory to investigate the formation energetics and electronic structure o...
Infrared spectroscopy of adsorbed CO was used to characterize the dependence of surface structure on deposition temperature during homoepitaxial growth on Cu(100). Intensity borrowing due to dipole coupling greatly enhances the absorption signal due to defect-bonded CO, making it possible to detect and quantify defect concentrations at the level of a few percent. For deposition temperatures bet...
In this paper, we propose a convolution filtering scheme for detecting small defects in low-contrast uniform surface images and, especially, focus on the applications for backlight panels and glass substrates found in Liquid Crystal Display (LCD) manufacturing. A defect embedded in a low-contrast surface image shows no distinct intensity from its surrounding region, and even worse, the sensed i...
Atomistic simulation techniques are used to investigate the defect properties of anatase TiO(2) and Li(x)TiO(2) both in the bulk and at the surfaces. Interatomic potential parameters are derived that reproduce the lattice constants of anatase, and the energies of bulk defects and surface structures are calculated. Reduction of anatase involving interstitial Ti is found to be the most favorable ...
One of the stages of quality control in porcelain producing factories is sorting that do with human eyes. Machine vision , including new methods for defect detection and sorting of different products. In this study, with defects diagnosis and as a result sorting porcelain, use from linear structured light pattern, triangulation techniques and rules governing mirrors. Also, among the defec...
Automated optical inspection systems are frequently utilized to sort out defective objects. However, those objects might actually be reworked or disposed. The combination of defect detection and specific processing in a single operation helps to reduce reworking time and waste. Defect detection on 3D objects is approached by combining the techniques of surface detection and geometry estimation....
In this paper a prototype system is described for the management and content-based retrieval of defect images in huge image databases. This is a real problem in surface inspection applications, since modern inspection systems may produce up to thousands of defect images in a day. We are using a noncommercial, generic content-based image retrieval (CBIR) system called PicSOM that is modified to ...
Background: Bernard-Soulier syndrome is a rare inherited bleeding disease caused by quantitative or qualitative defect of GPIb/IX/V, a platelet complex that binds the Von Willebrand factor. The expression of GPIb-IX-V complex can be evaluated by flow cytometry and confirmed by the absence of ristocetin-induced platelet aggregation in platelet-rich plasma. The main aim of the present study was t...
