Coatings with vertical gradients in composition were produced by drying an aqueous polymer dispersion containing both charged and neutral particles. After drying, the neutral component was enriched at the film/air interface. The spontaneous vertical segregation between the two types of particles goes back to a difference in collective diffusivity. As the film dries, a layer enriched in polymer ...
This paper deals with the design of an H∞-observer to estimate the state variables of the vertical car dynamics to be used for suspension control applications. The proposed methodology allows to cope with both the disturbance decoupling problem (for the road profile effects) and the implementation issue (through observer pole placement). The considered model is a 7 DOF full-car vertical model s...
Global Positioning System radio occultation measurements by the FORMOsa SATellite mission3/Constellation Observing System for Meteorology, Ionosphere and Climate satellites were used to analyse the behaviour of the signature of the terdiurnal tide in sporadic E (ES) layers at midlatitudes (43–63 N). According to theory, the occurrence of ES is expected when the vertical zonal wind shear, which ...
Three-field simulations of interchange turbulence are presented for a simple magnetized toroidal plasma with a vertical magnetic field. The simulations show the presence of two turbulent regimes characterized by low (L) and high (H) confinement properties. We evaluate analytically the properties of the L regime, obtaining expressions for the plasma gradients and for the density and heat fluxes ...
The goal of image or video quality assessment is to evaluate if a distorted image or video is of a good quality by measuring the difference between the original and distorted images or videos. In this paper, to assess the visual quality of an arbitrary distorted image or a compressed video, visual features of the image or video are compared with those of the original image or video instead of d...
Low-pressure hydride vapor phase epitaxy (HVPE) is being used for the regrowth of thick GaAs on orientation-patterned templates for nonlinear optical frequency conversion. We have achieved epitaxial growth rates of 200um/h and produced millimeter-thick films in 10-h-long growth runs. A critical problem in the HVPE regrowth of orientation-patterned GaAs is the preservation of the original patter...
We show that when the gravitational force is correctly calculated in dealing with the vertical hydrostatic equilibrium of black hole accretion disks, the relationship that is valid for geometrically thin disks, i.e., c s /Ω K H = constant, where c s is the sound speed, Ω K is the Keplerian angular velocity, and H is the half-thickness of the disk, does not hold for slim disks. More importantly,...

We derive radial and vertical distributions of H i and H2 gas densities in our Galaxy by using the terminal velocity method. We calculate the molecular fraction (fmol) defined as the ratio of the molecular hydrogen to total hydrogen gas density at galactic longitude l = 33◦ ∼ 64◦ and galactic latitude b = −2◦ ∼ +2◦. The thickness of the molecular dominant region (fmol ≥ 0.8) is approximately co...
