We calculate the dephasing rate due to magnetic impurities in a weakly disordered metal as measured in a weak-localization experiment. If the density nS of magnetic impurities is sufficiently low, the dephasing rate 1/tauphi is a universal function, 1/tauphi=(nS/nu)f(T/TK), where TK is the Kondo temperature and nu is the density of states. We show that inelastic vertex corrections with a typica...

This paper aims to study a 3 kW wireless power transfer system for electric vehicles. First, the LCL-LCL topology and LC-LC series topology are analyzed, and their transfer efficiencies under the same transfer power are compared. The LC-LC series topology is validated to be more efficient than the LCL-LCL topology and thus is more suitable for the system design. Then a novel q-Zsource-based onl...

A number of properties of Young raising operators as applied to S-functions and Schur Q-functions are noted. The order of evaluating the action of inverse raising operators is found to require careful specification and the maximum power of the operators bij is determined. The operation of the inverse raising operator on a partition .A is found to be the same as for its conjugate t A new definit...

Wireless power transfer is rapidly advancing in its ability to efficiently transfer power to a variety of devices. As the efficiency increases, more applications for these systems arise. Since magnetic resonant wireless power transfer can only transfer a small amount of power, most current applications only focus on powering low-powered devices. Wireless Sensor Networks are composed of many low...

This paper investigates ultrasonic transcutaneous energy transfer (UTET) as a method for energizing implanted devices at power level up to a few 100 mW. We propose a continuous wave 673 kHz single frequency operation to power devices implanted up to 40 mm deep subcutaneously. The proposed UTET demonstrated an overall peak power transfer efficiency of 27% at 70 mW output power (rectified DC powe...

Background: Studies on how the shoe insole hardness regulate joint stiffness and transfer energy in the lower extremity during jump landing are scarce. The current study aimed to determine the effectiveness of shoe insole changes in joint power and stiffness during landing from jumps. Methods: Fifteen healthy male athletes volunteered to perform jump-landing in various shoe insole conditions. ...

One of the concepts in restructuring the electric power industry is the ability to accurately and rapidly quantify the power transfer so-called as the available transfer capability (ATC). Accurate identification of ATC provides vital information for both planning and operation of the bulk power market in reserving transmission services. There are various methods used to determine ATC such as th...

In this paper, we analyze a noise-to-jitter transfer function on DLL (Delay Locked Loop) considering power supply noise effects on PDN (Power Distribution Network). Noise-tojitter transfer function of DLL circuit can be estimated by using single-tone power supply noise analysis. Noise transfer function through the PDN can be obtained from transfer impedance of hierarchical PDN using TLM (Transm...

With the rapid development of wireless power transfer (WPT), self-resonant WPT system without using additional compensation capacitors has attracted attention. However, most reported systems have low (less than 100 W) and high operating frequencies at megahertz. In this article, four multilayer, coil pads with different dielectrics are designed experimentally validated. The aim article is to in...
