The objective of this research was to produce prototype of an early warning system based on SMS for detection the rising level of ammonia gas in embroidery wastewater treatment of leather tanning industry.The systems consist of three parts, those were data input, data processing, and output.Ammonia gas sensor as a detector that produces an analog D
Analysis of Oil Distribution and Reduction of Axial Force due to Oil Supply in a Multi-Plate Clutch
Wet multi-plate clutches enable safety-critical operations in various types of powertrains.Ensuring sufficient oil coverage on each friction interface of industrial clutches is achieved by pressurized oil supply.The challenge of building capable test rigs to study oil and pressure distribution inside a practically relevant loaded clutch and the lim
Secure channel estimation model for cognitive radio network physical layer security using two-level shared key authentication
Abstract Physical Layer Security (PLS) in Cognitive Radio Networks (CRN) improves the confidentiality, availability, and integrity of the external communication between the devices/ users.The security models for sensing and beamforming reduce the impact of adversaries such as eavesdroppers in the signal processing layer.To such an extent, this arti
Investigation of characteristic hemodynamic parameters indicating thinning and thickening sites of cerebral aneurysms
Cellular and animal experiments and computational fluid dynamics (CFD) have revealed that mechanisms of the initiation, growth and rupture of a cerebral aneurysm are related to hemodynamics.By direct observation of a cerebral aneurysm during craniotomy, thinning or thickening sites can be found on the aneurysmal wall.The thinning site of a cerebral
