Comparative Study of P-P and P-U Based Acoustic Vector Sensors for Underwater Application

Full-duplex underwater acoustic communications via self-interference cancellation in space

“…Apart from directly measuring the particle velocity, which is called P-U method and P-P method, which only measures pressure is more commercially practical. The P-P method is based on the estimation of pressure gradient by setting closely located pressure sensors [34]. The AVS we propose in this research takes advantage of P-P method with structure in Fig.…”

Design Synthesis and Characterization of Novel Quinazolin-4(3H)-one Derivatives with Anticipated Pharmacological Efficacy

“…The antimicrobial and antiinflammatory activities of these derivatives were investigated [2]. Thirty new 2-(substituted)-3-{[substituted]amino}quinazolin-4(3H)-one were designed and synthesized keeping in view the structural requirement of pharmacophore and evaluated for anticonvulsant activity and neurotoxicity [3]. A series of novel Schiff bases were synthesized by condensation of 3-amino-6,8dibromo-2-phenylquinazolin-4(3H)-ones with different aromatic aldehydes via cyclized intermediate 6,8-dibromo-2-phenyl benzoxazin-4one.…”
