Abstract: Biogas promises bioenergy to be developed as a renewable fuel to reduce the fossil energy crisis.Biogas raw material can be derived from tofu liquid waste.Biogas is processed by anaerobic digestion.This study aimed to develop a simulation of the kinetic model variations of biogas production from tofu liquid waste.The results showed that t
In the satellite microwave power transmission (MPT) system, antenna arrays are usually adopted for a higher gain.For the passive wideband antenna array, wideband power dividers are essential when the feed network is constructed.Because the microstrip-slotline coupled power divider could achieve wide bandwidth and compact size at the same time, it b
The COVID-19 pandemic has generated a great impact on public health resta moisturizer all over the world.In order to control it, many strategies had been adopted.Nevertheless, not enough emphasis has been given to improving the immune system of the persons, which is, probably, a better solution to this and other pandemics.With this purpose, an educ
To defend against poisoning attacks and free-riding attacks conducted by malicious sensing terminals in crowd sensing-based collaborative spectrum sensing (CCSS), a novel audit game-based defense scheme was proposed, which combined lawn chairs 9 inches off the ground the pre-deterrence and post-punishment mechanisms.Firstly, considering the audit b
