This paper addresses the problem of channel tracking and equalization for multi-input multi-output (MIMO) time-varying frequency-selective channels. These channels model the effects of inter-symbol interference (ISI), co-channel interference (CCI), and noi ...

Five bonds form in one pot, from three well-designed yet readily accessible substrates. Simply mixing an o-alkynyl aniline, e.g., 2-H2NC6H4C==CCO2Me, an aldehyde, e.g., heptanal, and ammonium chloride in toluene at room temp., followed by addn. of an isocy ...
Any innovative design of a chem. or biol. reactor has to consider the dynamics of the primary phys. and chem. steps involved in the overall process. For homogeneous highly viscous systems the mixing time is of crucial importance for the product quality. In ...
Structure and morphology of solid particles in precipitation from aqueous solutions correlate with formation (solution) conditions and thus reflect the growth mechanism. Calcium phosphate precipitation obtained from dilute aqueous solutions at room and bod ...
Dispersive mixing of high viscosity ratio blends was studied in a converging flow using a capillary rheometer equipped with dies having different entry profiles. Three inhomogeneous bimodal polyolefin blends, with stress-dependent viscosity ratios ranging ...
The role of the confinement potential symmetry on the electronic and optical properties of quantum mires is systematically studied. In a wide class of quantum mires with mirror symmetry we evidence a new set of optical transitions resulting both from band ...
Experimental results on storage and mixing of ten-percent-talin/water ice slurries are presented. For this purpose a system with a storage tank, with a volume of 1000 liters and a mixing device containing three slightly inclined cones, was investigated. In ...

Calcium phosphate precipitation obtained from aqueous solutions at room and body temperatures and pH 5.5-7.5 were investigated by high-resolution transmission electron microscopy (HRTEM), transmission electron diffraction, scanning electron microscopy (SEM ...
Computational Fluid Dynamics (CFD) has been employed for the optimization of the mixing efficiency of a Kenics static mixer. A series of numerical simulations has been undertaken for non-creeping flow conditions to determine the optimal twist angle of the ...
Mixing liquids on the micro-scale is difficult because the low Reynolds numbers in microchannels and in microreactors prohibit the use of conventional mixing techniques based on mechanical stirring which induces turbulence. Static mixers can be used to sol ...
