Performance Analysis of cooperative SWIPT System: Intelligent Reflecting Surface versus Decode-and-Forward
In this paper, we explore the impacts of utilizing intelligent reflecting surfaces (IRS) in a power-splitting based simultaneous wireless information and power transfer (PS-SWIPT) system and compare its performance with the traditional decode and forward relaying system. To analyze a more practical system, it is also assumed that the receiving nodes are subject to decoding cost, and they are on...
متن کاملPassive and Active Glenohumeral Joint Stiffness
1. Introduction It is not clear how different portions of the capsuloligaments and muscles contribute to GH stability. Since GH instabilities occur frequently in various shoulder injuries, it is important to understand the restraining forces provided by various structures in the GH-joint. A better understanding of the GH stiffness will also help improve existing shoulder models by including GH ...
متن کاملMulti-axis passive and active stiffnesses of the glenohumeral joint.
OBJECTIVE To investigate passive and active glenohumeral stiffness in the anterior, posterior, superior, and inferior directions at different lateral positions of the humerus. DESIGN Glenohumeral stiffness along multiple axes was determined in fresh-frozen shoulder specimens under both passive (no simulated muscle contraction) and active (with simulated muscle contraction) conditions. BACKG...
متن کاملJoint Temporal-spatial Reference Beamforming: Eig Beamforming
Traditional methods for beamforming can be grouped in two families, the time reference beamformer and the spatial reference beamforming. Nevertheless, the increasing demand on receivers for location systems and high bandwidth over frequency selective fading able to properly manage multipath and co-channel interference motivates the need for versatile processing able to cope with both problems. ...
متن کاملControl Processes Optimization for Mechanical Systems with Active, Semi-Passive and Passive Actuators
The influence of the geometric parameters of two-link manipulator on the energy expenditure necessary for the implementation of a given movement is investigated. It is proposed approximation-compensatory approach to replace the active actuators in the joints of the manipulator on semi-passive and entirely passive actuators. Advantages and disadvantages of such replacement are analyzed and the f...
