Cochannel interference introduced by frequency reuse under space division multiple access can be reduced by controlling the frequency sharing according to the users’ spatial separability. The system avoids placing highly correlated users in space into the same spatial multiplexing group. This paper describes a user spatial compatibility evaluation criterion based on channel matrix structure ana...

BACKGROUND Diabetes mellitus is a disease lack of insulin, which has severely delayed and impaired wound healing capacity. In the previous studies, various types of scaffolds and growth factors were used in impaired wound healing. However, there were several limitations to use them such as short half-life of growth factors in vivo and inadequate experimental conditions of wound-dressing materia...

The researcher measured the least number of frequency response functions required for the identification of modal parameters, in order to simplify the identification of modal properties of such systems. In this work, the orbital machines are supposed to be a combination of orbital and non-orbital components. Structural Approach specified the identification of dynamic properties only to those ph...

Three different calibration approaches were applied in HPLC/MS/MS using electrospray ionization for the determination of 14 diverse pesticide residues at different levels in a variety of food matrixes. This study was conducted as part of a 4 day training course for 17 chemists to learn the "quick, easy, cheap, effective, rugged, and safe" (QuEChERS) approach to pesticide residue analysis in foo...

In this paper, we present a new speech perceptual hashing authentication algorithm based on wavelet packet decomposition (WPD) for speech content authentication. Firstly, a wavelet packet coefficients matrix of wavelet reconstruction is generated from an original speech signal after high frequency pre-processing followed by wavelet packet decomposition. Secondly, the wavelet packet coefficients...

For thermal management applications, copper (Cu) metal matrixes reinforced by carbon are undoubtedly one of the most promising composites for heat spreaders In frame this work, hard Cu matrix having anisotropic conductivity were fabricated using flakes coated with carbonized polydopamine. The simply immersing them into a dopamine aqueous solution, then they submitted to treatment under dihydrog...

In this paper, an image-based method-non-uniform light field mapping is proposed which combines edge-based surface light field partition and non-uniform decomposition of light field matrixes for real-time rendering. Through this method view-dependent appearance of scenes with complex reflectance properties can be rendered in real-time. This method obtains surface light field by resampling the d...

In this work two new alloys were obtained by extrapolation from a wellknown high entropy alloy, the equimolar CoNiFeMnCr one. This was doneby addition of carbon and tantalum, Ta being one strongestMC-former elements. They produced conventional casting underinert atmosphere. The microstructures characterized X-raydiffraction, metallography, electron microscopy, energy dispersionspectrometry. The...

BACKGROUND Real-time PCR is the technique of choice for nucleic acid quantification. In the field of detection of genetically modified organisms (GMOs) quantification of biotech products may be required to fulfil legislative requirements. However, successful quantification depends crucially on the quality of the sample DNA analyzed. Methods for GMO detection are generally validated on certified...

To provide an objective measure of the correlation between the internal energy content of ions generated by matrix-assisted laser desorption/ionization (MALDI) and the matrix properties, a series of well-characterized benzyl-substituted benzylpyridinium salts were used as thermometer molecules (TMs). To determine the internal energy variations of analyte ions, the survival yields of TM molecula...
