Selective deposition of SiO2 nanoparticles was demonstrated on a soda-lime glass surface with a periodic sodium deficient pattern formed using the electrical nanoimprint. Positively charged SiO2 particles generated using corona discharge in a cyclic siloxane vapor, were selectively deposited depending on the sodium pattern. For such phenomena to occur, the sodium ion migration to the cathode si...

We address the problem of carrier frequency offset (CFO) synchronization in Orthogonal Frequency Division Multiplexing (OFDM) communications systems in the context of frequency-selective fading channels. The mathematic model of OFDM systems with cyclic prefix (CP) and virtual subcarrier is derived. And we propose the shift-invariance CFO estimation algorithm based on DOA-MATRIX method. After th...

The reduction of high harmonic content in the grid side current is achieved by different harmonic compensating techniques. In order to accomplish it, selective harmonic compensation is carried out in grid-connected photovoltaic inverters by means of resonant harmonic compensators. The harmonic compensator shown in this paper is lead lag compensator. This paper shows a systematic design procedur...

To reduce the high-order harmonics produced by the high-power pulse width modulated (PWM) converters, selective harmonic elimination (SHE) scheme is commonly used due to its superior harmonic performance at low switching frequency. This Project proposes an active compensation method through the PWM control of SHE phase angle. An application example on a high-power PWM current-source rectifier (...

The effect of three organic aromatic salts - Phenyltrimethylammonium (PhTMAB), benzyltrimethylammonium (BzTMAB) and benzyltrimethylammonium (BzTEAB) bromides - on the micellization of sodium dodecylsulfate has been investigated by conductometric method. The critical micelle concentration (CMC) values were found to decrease with increase in the concentration of the aromatic ammonium salts. Therm...

In this paper, a new approach is proposed for voltage and current harmonics compensation in grid-connected microgrids (MGs). If sensitive loads are connected to the point of common coupling (PCC), compensation is carried out in order to reduce PCC voltage harmonics. In absence of sensitive loads at PCC, current harmonics compensation scenario is selected in order to avoid excessive injection of...

In work on Wistar rats with experimental crush syndrome and acute alcohol intoxication shown that alterations of «metabolic profile» are stipulated by the lymphatic system, which emerges as an active component to urgent adaptation in critical situations. It is shown by the expressed infringements of an exchange of electrolytes in plasma. lymph and myocardium at the rats, that can make a part of...

the performance of selective media ltb, (leauryl tryptose broth), mmgm (minerals modified glutamate medium), bgbb (brilliant green bile broth), for the detection of e.coli in water in water, were compared and the following result were obtained: the mmgm found to be unsuitable as confirmatory medium for the detection of e.coli at 44 c, due to the occurrence of an unacceptable number of the false...

We examine the interaction between risk (uncertainty) and production efficiency in determining pay-performance sensitivity in optimal executive compensation. Particularly, we show that the risk-incentive trade-off is exacerbated (attenuated) as production efficiency increases when the efficiency level is greater (less) than the level of compensation risk. This result suggests that the optimalit...

Nowadays, abdominal catheterizations are mainly guided by 2D fluoroscopic imaging from one view, which complicates this task due to missing depth information, vessel invisibility, and patient motion. We propose a new technique for 3D navigation of guide wires based on singleplane 2D fluoroscopic views and a previously extracted 3D model of the vasculature. In order to relate the guide wire, whi...
