A new method of optimization using the thru-focus MTF is described. Operands based on the thru-focus MTF peak and distance from the evaluation plane to the peak are investigated for their insensitivity to local minima in DLS optimization. The new optimization method is generally compared to conventional MTF optimizati…

The interaction in the CaCl2-MgCl2-(NH4)2HPO4-NH3-H2O and CaCl2-MgCl2-(NH4)2HPO4-(C6H11NO4) n -NH3-H2O systems at 25°C has been investigated by the solubility (Tananaev’s residual concentration) method and by pH measurements. Magnesium-containing calcium hydroxylapatites with the general formula Mg x Ca10 − x (PO4)6(O…
The electronic band structures of periodic models for Si–H compounds are investigated by the density functional theory. Our results show that the Si–H compound changes from indirect-gap semiconductor to direct-gap semiconductor with the increase of H content. The density of states, the partial density of states and th…
Although forming of porous metal is demanded for industrial applications, the deformation characteristics have not been investigated sufficiently. In this study, lotus-type porous copper is processed by multi-pass cold rolling. At the early stage of rolling, the elongation of the porous copper in the rolling direction…

The corrosion of low-carbon steels in natural deep-well water of Moldova and in a number of process environments is studied. Peculiarities of the corrosion process in the model solutions depending on the chemical composition, total salt content, total and carbonate hardness, and other parameters of aqueous environment…
A series of potassium titanyl phosphate single crystals doped with zinc (KTP: Zn) is grown by spontaneous flux crystallization. Their properties and the way the additive is implanted in the crystal lattice are studied. The inclusion of zinc atoms in the KTP structure is evidenced by the data of chemical analysis and t…
Experimental data on the nonlinear dynamic responses of barium titanate (discontinuous phase transition, PT), triglycine sulphate (continuous PT), as well as the prototype relaxor lead magnoniobate, and the weakly doped quantum paraelectric K0.995Li0.005TaO3are presented. The classic ferro-electrics display all featur…
With the increasing number of processor cores in chip multi-processors (CMPs), 2D Mesh has been gaining wide acceptance for inter-core on-chip communication. Program performance is more sensitive to the router latency than to the link bandwidth. This paper presents a low latency Dynamic Virtual Output Queues Router (D…
We studied the complete set of elastic constants Cij and internal frictions tensor Qij−1 of anisotropic decagonal Al72Ni18Co8 single quasicrystal by electromagnetic acoustic resonance at low temperatures, to 5 K. Most Cij(T) showed usual stiffening upon cooling and their temperature behaviors are well characterized by…
The behavior of excited PyS− with the quencher NO 2 − in an ionomer solution of anion-conductive resin and in the nanochannels of an anion-conductive membrane was investigated by luminescence quenching measurements. Compared with the behavior of an excited Ru(bpy) 3 2+ -MV2+ system in the presence of Nafion, the mobil…

Differential scanning calorimetry, X-ray diffraction analysis, polarization microscopy, methods of cloud points and static sorption, and a polarization-photoelectric installation were used to make a thermodynamic analysis of systems constituted by hydroxypropylcellulose, poly(ethylene glycols), and water. The thermody…
Lotus-type porous carbon steel (lotus carbon steel) plates were fabricated by continuous casting technique in a pressurized nitrogen atmosphere. The experiments were done both with adding 0.3wt% of NiO powder in molten carbon steel in a ceramic crucible and without NiO powder. The lotus carbon steel fabricated without…

The excellent spreading and wetting behaviour of superspreader solutions has been known and extensively studied over recent years. However, explanations for spreading dynamics and accompanying mathematical models have not yet proved completely successful. Many attempts have been made to quantify the spreading exponent…
BaxSr1-xTiO3 (BST) thin films were deposited by modified CSD, in which partially hydrolyzed Ti-alkoxide was reacted with Ba-Sr precursor solution to form highly polymerized BST precursor solutions, leading to the better electrical properties of the resultant thin films. BST precursor solutions of 0.1 M were prepared t…
