Exact transmission moments in one-dimensional weak localization and single-parameter scaling
, 2003 We obtain for the first time the expressions for the mean and the variance of the transmission coefficient for an Anderson chain in the weak localization regime, using exact expansions of the complex transmission- and reflection coefficients to fourth ...

Thermophysical Properties of the Desulphurization Slags With Various CaS and CaO/Al2O3 Ratio
Advanced Engineering Materials, EarlyView.This article investigates how CaS content and the CaO/Al2O3 ratio influence the thermophysical properties of desulphurization slags. Using experimental measurements and thermodynamic simulations, this study reveals complex effects on viscosity, surface tension, and density, providing new insight into slag structure and phase behavior under ...

Evaluating Energy Absorption Performance of Filled Lattice Structures
Advanced Engineering Materials, EarlyView.Maximum stress must be considered to robustly evaluate energy absorber designs. This approach was applied to compare all types of absorbers in a single Ashby diagram and determine the utility of filling lattice voids with a second material. High‐performance fillers can improve the performance of lattices that are limited by buckling or catastrophic ...

Non-stationary thermal mode of a room at integrated regulation of split systems
Magazine of Civil EngineeringDue to the non-linearity of the propagation of temperature waves in massive fences, one of the most difficult control objects is an air-conditioned room equipped with automated microclimate systems, especially if complex algorithms are used for ...

Resonances in 1D disordered systems: localization of energy and resonant transmission
, 2003 Localized states in one-dimensional open disordered systems and their connection to the internal structure of random samples have been studied. It is shown that the localization of energy and anomalously high transmission associated with these states are

Generalized Bloch wave analysis for fiber and waveguide gratings [PDF]
, 1997 We have developed a generalized Bloch wave approach for the analysis of aperiodic gratings. This method yields both a macroscopic (i.e., reflection or transmission coefficient) as well as a microscopic (i.e., dispersion diagram and microstructure of the ...

Advanced Engineering Materials, EarlyView.New features on yttria‐stabilized zirconia after exposure at 1500°C: Newly discovered pyramidal structures on an old material. After exposure at 1550°C on the cross section of YSZ new features, namely pyramidal structures are discovered. These structures grow with time, increase in numbers, appear as singularities, are often arranged in strings, and ...
