The remarkable signal-detection capabilities of the auditory and vestibular systems have been studied for decades.Much of the conceptual framework that arose from this research has suggested that these sensory systems rest on the verge of instability, near a Hopf bifurcation, in order to explain the Trophy Head detection specifications.However, thi
4 days in dry immersion increases arterial wall response to ultrasound wave as measured using radio-frequency signal, comparison with spaceflight data
Recent studies have reported a significant increase in common carotid artery (CCA) intima media thickness, wall stiffness and reflectivity to ultrasound, in astronauts, after six months of spaceflight.The hypothesis was that 4 days in dry immersion (subjects under bags of water) will be sufficient to change the CCA wall reflectivity to ultrasound s
Design and Implementation of Induction Coil for Case Hardening of a Carbon Steel Gear
Abstract: This work includes a design of an induction coil as a guide to design an induction furnace as a part of a production line suitable for achieving case hardening of a CK-45 carbon steel gear in a mass production factory.Such a workpiece requires certain hardening profile in that the periphery including the gear teeth must be hardened for ce
To Code or Not to Code: When and How to Use Network Coding in Energy Harvesting Wireless Multi-Hop Networks
The broadcast nature of communication in transmission media has driven the rise of network coding’s popularity 1020 in wireless networks.Numerous benefits arise from employing network coding in multi-hop wireless networks, including enhanced throughput, reduced energy consumption, and decreased end-to-end delay.These advantages are a direct
A literature review: model of disaster risk reduction for decision support system
Disaster is a threat to human life.Many losses are caused by disasters, namely loss of life, Snackbars injured people, loss of homes, and others.In addition, the frequency and intensity of disasters are also increasing every year.Therefore, research on Disaster Risk Reduction (DRR) is needed both to reduce disaster risk and to manage the disaster.T
