Full-Duplex MIMO Relaying Powered by Wireless Energy Transfer

, 2015
We consider a full-duplex decode-and-forward system, where the wirelessly powered relay employs the time-switching protocol to receive power from the source and then transmit information to the destination.

Growth of single-crystal columns of CoSi2 embedded in epitaxial Si on Si(111) by molecular beam epitaxy [PDF]

, 1989
The codeposition of Si and Co on a heated Si(111) substrate is found to result in epitaxial columns of CoSi2 if the Si:Co ratio is greater than approximately 3:1. These columns are surrounded by a Si matrix which shows bulk-like crystalline quality based

Investigation of Drive Performance of Motors in Electric Loaders with Unequal Transmission Ratios—A Case Study

World Electric Vehicle Journal
Research on electric wheel loaders (EWLs) has predominantly focused on battery management, hybrid technologies, and energy recovery. However, the influence of motor types and drivetrains on the drive performance of EWLs has received little attention in ...

A Search Method of NN Reducer’s Transmission Ratio

Jixie chuandong, 2022
The transmission ratio of NN reducer is discrete and nonlinear, and the gear matching method determines the volume and stability of a reducer. In previous studies， most scholars tried to find out the key parameters affecting the change of transmission ...

Approach for the Calculation of Transmission Ratios and Their Errors in 4-Bar Mechanisms, Considering the Precision Variations by Dimensional Tolerances

AppliedMath
This paper presents research and theoretical development of a mathematical model that, first, allows us to understand how the positional exactitude of the output link of a four-bar mechanism depends on the manufacturing dimensional tolerances.

Dual Cone Continuously Variable Transmission Model Controlled by LabVIEW

Machines
This paper outlines the design, development, and practical implementation of a rubber belt-driven dual cone continuously variable transmission (CVT) model. This model enables a demonstration of stepless changes in the transmission ratio between input and

Spam1-associated transmission ratio distortion in mice: Elucidating the mechanism

Reproductive Biology and Endocrinology, 2005
Background While transmission ratio distortion, TRD, (a deviation from Mendelian ratio) is extensive in humans and well-documented in mice, the underlying mechanisms are unknown.

The viral content ratio between abdomen and head is informative of the relative efficiency with which Bemisia tabaci populations transmit begomoviruses. [P.12] [PDF]

, 2015
Begomoviruses (family Geminiviridae) are transmitted by the whitefly Bemisia tabaci in a circulative non propagative manner. B. tabaci is a species complex composed of at least 24 morphocryptic species which differ in host range, insecticide resistance ...
