While reconfigurable intelligent surface (RIS) technology has been shown to provide numerous benefits to wireless systems, in the hands of an adversary such technology can also be used to disrupt communication links.This paper describes and analyzes an RIS-based attack on multi-antenna wireless systems that operate in time-division duplex mode unde
One of the mathematics learning purposes is using reasoning in patterns and properties, mathematical manipulation in making generalization, compiling evidence, or explaining mathematical ideas and statements.Mathematical learning based on behaviorism has been seen as less successful in instilling character of mathematics reasoning.Therefore, it is
Fraction of photosynthetically active radiation (FPAR), as an important index for evaluating yields and biomass production, is key to providing the guidance for crop management.However, the shortage of good hyperspectral data can frequently result in the hindrance of accurate and reliable FPAR assessment, especially for wheat.In the present researc
We study the features of the nonlinear optical response of silver nanoparticles (Ag NPs) of spherical and triangular shapes synthesized using a citrate-borohydride approach and their mixtures with methylene blue (MB+).The Z-scans at BOSCH Serie 6 BFL554MS0B Built-in Solo Microwave - Stainless Steel the wavelengths of 532 nm using 10 ns pulses were
