The occurrence of food safety incidents such as “Sanlu Milk Powder” make the public have doubts about the effectiveness of food quality safety market admittance system. Therefore, studying and evaluating the effectiveness of food quality safety market admittance system has become a problem to solve urgently. The article combines the theory of management science with the practice of food quality...

The goal of the present study was to determine the effects of prolonged, intermittent flexion on trunk neuromuscular control. Furthermore, the potential beneficial effects of passive upper body support during flexion were investigated. Twenty one healthy young volunteers participated during two separate visits in which they performed 1 hour of intermittent 60 seconds flexion and 30 seconds rest...

The transfer-admittance of n and p-channel MOS transistors has been measured under the condition of a uniform channel. These MOS transistors all showed a measurable “slow interface state drift” <O.l-0.2V. The transfer-susceptance has been found to show a significant peak value in moderate inversion. Over the entire moderate and strong inversion region the transfer-susceptance remains constant a...

The formulation of the wall admittance of a circular microstrip antenna by the spectral domain method is presented. The circular microstrip antenna is calculated using the cavity model. The electromagnetic fields within the antenna cavity are determined from the impedance boundary condition at the side aperture. The contribution from the region outside the antenna is taken into account by the w...

In this paper the design method leading to the radio-frequency (RF) filters working in the pure current mode is shown. New active elements called current mirrors and inverters (CMI) are presented, a generalized variant (GCMI) is used for the design purposes, and a universal version (UCMI) is fitted to the filtering-circuit final solution. Initial autonomous circuits are derived from the full ad...

Admittance reshaping is a widely used strategy to address the converters low-frequency stability issues in weak grid, caused by PLL and its interaction with dc ac voltage controls. However, asymmetric control of $d$ - notation="LaTeX">$...

The full-wave model of underground cables is presented. The solutions of this model in frequency domain, applied in underground insulated, cable is evaluated. To allow the inclusion of this formulation in EMT programs a rational vector fitting of the propagation constant, characteristic admittance Yc and the propagation function H in frequency domain is presented. The simulations in time domain...

The admittance of an infinite cylindrical antenna is calculated as a function of exciting frequency and exciting gap thickness. The results obtained show that an asymptotic analytical expression derived for the susceptance by Chen and Keller and also later by Fante, is strictly valid only in the limit of "Vanishing gap thickness. An altenate analYtical. form is presented-for die susceptance, wh...
