Qos Enhancement in Manet by Directional Power Control

open access: yesCommunications, 2014
In this paper, the 4-Way Directional Power Control with Recoil Loop (4WDPCRL) protocol for power control of directional antennas is presented. We propose the scheme with using of control packets (RTS/CTS/DATA/ACK) for exchanging information about node's ...

Study on RP-3 Aviation Fuel Vapor Concentration

open access: yesAerospace, 2023
Fuel vapor concentration is a key parameter for assessing the flammability of aircraft fuel tanks. However, the current research on RP-3 (Rocket Propellant-3) fuel vapor concentration is inadequate. This study categorizes fuel components by the number of

Enhancing the power of understanding [PDF]

open access: yesBolgoda Plains, 2021
Power of understanding is a rewarding cognitive capacity required for all of us from early childhood to the highest level of intellectual settings. Among other things, the concept of understanding plays a vital role in education. When I was a second-year undergraduate, I was so curious to know why some of my colleagues could understand subjects much ...

Arraying of microphotosynthetic power cells for enhanced power output

open access: yesMicrosystems & Nanoengineering, 2022
AbstractMicrophotosynthetic power cells (µPSCs) generate power through the exploitation of living photosynthetic microorganisms by harvesting sunlight. The thermodynamic limitations of this process restrict the power output of a single µPSC. Herein, we demonstrate µPSCs in four different array configurations to enhance power output from these power ...
