Screen printing or thick film technology is a widely know approach to manufacture disposable and low-cost sensors and biosensors. Screen-printed electrodes can be manufactured with diverse conductive inks, shapes, and dimensions, depending on the analytical need. Besides their fabrication, these platforms are suitable to be customized with a variety of (nano)materials and bioelements. Herein, we highlight...
Nowadays Integrated Circuits (IC)s frequencies causes switching noises. To minimize the mentioned issue in IC designs were used decoupling capacitor (decap) cells to filter out noise in power network. In this paper, have been discussed two approaches of using decap cells in Universal Serial Bus Test Chip (USB TC). Firstly, designed USB TC with decoupling capacitor cells which place over the chip by...
This paper presents hybrid L- and P-stable implicit numerical methods for solving differential equations of electronic circuits and systems. Hybrid methods are developed on the basis of two known subclasses of implicit Runge-Kutta methods commonly referred to as Rado IIA and Lobatto IIIA methods. Comparative analysis of the known methods and the proposed hybrid methods demonstrates a high accuracy...
Stochastic Local Search (SLS) is one of the most popular approaches to Boolean satisfiability problem and solvers based on this algorithm have made a substantial progress over the years. However, nearly all state of the art SLS solvers do not attempt to find a good starting point, instead using random values. We present a heuristic for finding an initial assignment based on non-linear optimization...
The paper is devoted to the sampling theorem in frequency domain, which provides the possibility and method for reconstructing the integral Fourier transform of a time-limited signal over an infinite number of coefficients of its Fourier series. The theorem is formulated and proved under very general assumptions: for non-zero index of signal overview window and frequency samples non-multiplicity of...
The problems of parallelizing computations and increasing real performance are among the main ones for high-performance computing systems.

Methods for solving other problems of classical dataflow systems and traditional cluster supercomputers by the parallel dataflow computing system are also...
Estimation of multiplicative noise influence on the measurement error of information parameters of the useful signal. It is shown that the multiplicative noise leads to a bias of estimated parameters of the useful signal; taking into account a bias value allows us to have unbiased estimates. The expressions describing the relative accuracy of information parameters of the signal under the influence...
This paper presents the new face verification algorithm based on deep convolutional neural network.
