This article reviews and discusses a geometric perspective on the well-known fact in graph theory that effective resistance is metric nodes of graph. The classical proofs this make use ideas from electrical circuits or random walks; here we describe an alternative approach which combines (using simplices) algebraic Schur complement) ideas. These perspectives are unified matrix identity Miroslav...

Chromium carbide – nickel chromium powder Cr3C2-25wt.NiCr was plasma sprayed by a water-stabilized system WSP®. A series of experiments with variable feeding distance was carried out. Basic characterization of coatings was done by XRD, SEM and light microscopy plus image analysis. Microhardness was measured on polished cross sections. The main focus of investigation was on resistances against w...

Distance-bounding is a practical solution to be used in security-sensitive contexts, to prevent relay attacks. Its applied cryptographic role is definitely spreading fast and it is clearly far reaching, extending from contactless payments to remote car unlocking. However, security models for distance-bounding are not well-established and, as far as we know, no existing protocol is proven to res...

The electrical resistance and polarization effect of cement paste containing reinforcement were tested to research the anti-corrosion properties steel bars in paste. Moreover, microstructure composition passivation film rust on studied. water–cement ratio this study was 0.3, with 0.5% NaCl, 1% NaNO2, Benzotriazole, an assembly unit NaNO2 + Benzotriazole by mass added provide a chloride environm...
