A Cramér-Rao bound (CRB) for semi-blind channel estimators in redundant block transmission systems is derived. The derived CRB is valid for any system adopting a full-rank linear redundant precoder, including the popular cyclicprefixed orthogonal frequency-division multiplexing system. Simple forms of CRBs for multiple complex parameters, either unconstrained or constrained by a holomorphic fun...

We develop a new coordination contract of manufacturer-retailer in a distribution system. A revenue sharing contract based on retail price is modelled, which is more practical to handle channel conflict. We also integrate two concepts of CSR (Corporate Sociality Responsible) and Semi-TDPD (Semi Third Degree Price Discrimination) into our model. Semi-TDPD strategy makes it possible to exploit th...

Recently, porous materials on the base of semiconductor crystals arouse greater interest as photon crystals in terms of opto-electronic applications and formation of arrays of nano-elements with oneand zero-dimensionality. The crystals of porous silicon have been developed best to date. The obvious trends in this field now are towards using other materials for electrolytic etching, decreasing t...

The experimental charge and discharge profiles of a LiCoO2 electrode show that the overpotential of the electrode does not change much during alvanostatic charge, but changes significantly during galvanostatic discharge. Semi-empirical porous electrode models are presented to simulate he charge and discharge profiles of the LiCoO2 electrode. The symmetry factor is empirically assumed to decreas...

Simulating flow of a Bingham fluid in porous media still remains a challenging task as the yield stress may significantly alter the numerical stability and precision. We present a Lattice-Boltzmann TRT scheme that allows the resolution of this type of flow in stochastically reconstructed porous media. LB methods have an intrinsic error associated to the boundary conditions. Depending on the sch...

A strategy for the synthesis of covalent organic frameworks with open docking sites is developed. The docking sites are ordered on the channel walls and structurally predesignable for meeting various types of noncovalent interactions, thus opening a way towards designing supramolecular materials based on crystalline porous organic frameworks.

This paper deals with the analysis of an unsteady mixed convection flow of a fluid saturated porous medium adjacent to heated/cooled semi-infinite stretching vertical sheet in the presence of heat source. The unsteadiness in the flow is caused by continuous stretching of the sheet and continuous increase in the surface temperature. We present the analytical and numerical solutions of the proble...

Abstract. Porous poly(N-isopropylacrylamide) (PNIPAAm) hydrogels with pore diameters in the nanometer and micrometer range were synthesized using two variations of surfactant-based template method. We showed that smaller lead to faster swelling deswelling. A graphic representation a model describing kinetics explains assumption release uptake water is for larger specific surface area, diameters...
