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 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...

The reliability of different electrode admittance equations in the case of the Ag/Ag I electrode is critically discussed. It is shown that the admittance equation already derived for the' metal arnalgam/metal-Ion reversible electrode reaction coupled with reactant adsorption offers some advantages compared to the admittance equation for the reversible electrode reaction on the metal/metal-ion e...

In the paper the application of haptic joystick with magneto-rheological (MR) brake in control of electrohydraulic drive is presented. Two impedance and admittance control methods are shown. Basing on main equations describing electrohydraulic drive, the simulation model of an admittance control system is proposed. The results of chosen simulations are presented. Laboratory test stand is descri...

Piezoelectric wafer active sensors (PWAS) at high temperature with reliable operation are desired for structural health monitoring. The PWAS may be generalized as an electromechanical system because of the incorporation of electromechanical coupling. The basic principle of SHM method by PWAS is to monitor variation in the electro-mechanical (E/M) impedance/ admittance signature. The operational...

Knowledge reuse has long been an issue for organisations. The management, reuse and transfer of knowledge can improve project management capabilities (i.e., learning, memory, cycle time) resulting in continuous learning. Although knowledge management has been recognised as a critical success factor in programme management very little research has been conducted to date (Lycett, Rassau, & Danson...

In physics-based sound synthesis, it is generally possible to incorporate a mechanical or acoustical immittance (admittance or impedance) in the form of a digital filter. Examples include modeling of the termination of a string or a tube. However, when digital filters are fitted to measured immittance data, care has to be taken that the resulting filter corresponds to a passive mechanical or ac...

Abstract. This paper proposes admittance matrix models to approach the behavior of six modern multiport functional blocks called: differential difference amplifier, differential difference operational floating amplifier, differential difference operational mirror amplifier, differential difference current conveyor, current backward transconductance amplifier and current differencing transconduc...

In this paper an adaptive compliant motion control is presented for either constant admittance or constant force mode of operation. From a desired trajectory of the admittance and virtual position in the task space, a virtual trajectory is generated to follow the desired admittance. We are talking about admittance because at the interaction port of the end effector the force is measured and a g...
