In multichannel blind deconvolution (MBD) the goal is to calculate possibly scaled and delayed estimates of source signals from their convoluted mixtures, using approximate knowledge of the source characteristics only. Nearly all of the solutions to MBD proposed so far require from source signals to be pair-wise statistically independent and to be timely not correlated. In practice, this can on...

The synthetic hydroxyapatite is a very useful material for numerous applications in medicine as a biomaterial. One of the most economic manufacturing process is the precipitation route. In the present work, synthetic hydroxyapatite was prepared using the precipitation route, starting with aqueous solutions of calcium nitrate (Ca(NO3).4H2O ) and ammonium phosphate (H2(PO4)NH4). The effects of ph...

Abstract The corrosion mechanisms and kinetics of a Mg-rich alkali aluminoborosilicate glass simulating UK high-level waste (CaZn28) were investigated upon dissolution in synthetic cement solutions. Dissolution varied as function the different pH alkali/alkaline earth content each solution. High resolution microscopy spectroscopy techniques ascertained nature interface between TEM-EDS revealed ...

In some real applications of Statistical Process Control it is necessary to design a control chart to not detect small process shifts, but keeping a good performance to detect moderate and large shifts in the quality. In this work we develop a new quality control chart, the synthetic T control chart, which can be designed to cope with this objective. A multi-objective optimization is carried ou...

Humanitarian demining by scientific methods is a very important technical issues and ground penetrating radar (GPR) can be one of the best solutions for this difficult task. However, strong clutter makes difficult for detecting buried landmines in real situations. We have developed a synthetic aperture based GPR and tested its capabilities by experiments. We found that synthetic aperture radar ...

In previous studies of the reactions of fluoride ion with synthetic hydroxylapatite and powdered enamel and dentin (1,2), it was thought that low concentrations of fluoride ion might be affecting the rate of recrystallization of the apatites. Neuman et al. (3) found that fluoride impregnation had no effect on calcium and phosphate exchange of glycol-ashed bone. The experiments described below w...

As a reference platform for in vitro synthetic biology, we have developed a prototype flow microreactor for enzymatic biosynthesis. We report the design, implementation, and computer-aided optimisation of a three-step model pathway within a microfluidic reactor. A packed bed format was shown to be optimal for enzyme compartmentalisation after experimental evaluation of several approaches. The s...

vanadium is quantitatively retained on 2-nitroso-1-naphhthol-4-sulfonic acid tetradecyldimethlbenzyammonium chloride onto microcrystalline naphthalene in the ph range of 3.0-4.0 from a large volume of aqueous solutions of various alloys and synthetic samples. after filtration, the solid mass consisting of the vanadium complex and naphthalene was dissolved with 5.0 ml of dimethylformamide and th...

Automatic design of synthetic gene circuits poses a significant challenge to synthetic biology, primarily due to the complexity of biological systems, and the lack of rigorous optimization methods that can cope with the combinatorial explosion as the number of biological parts increases. Current optimization methods for synthetic gene design rely on heuristic algorithms that are usually not det...
