On transmission efficiency of quantum modulations [PDF]

open access: yesQuantum Studies: Mathematics and Foundations, 2019
In quantum information theory, it is important to find modulations with low information loss for noisy channels. In this paper, using the quantum dynamical entropy and the quantum dynamical mutual entropy, we investigate the transmission efficiency of two quantum modulators through attenuation channels.

On Adaptive Energy-Efficient Transmission in WSNs [PDF]

open access: yesInternational Journal of Distributed Sensor Networks, 2013
One of the major challenges in design of wireless sensor networks (WSNs) is to reduce energy consumption of sensor nodes to prolong lifetime of finite capacity batteries. In this paper, we propose energy-efficient adaptive scheme for transmission (EAST) in WSNs. EAST is an IEEE 802.15.4 standard compliant.

Separation of ions with the same charge to mass ratio from a collision experiment [PDF]

open access: yesJournal of the Serbian Chemical Society, 2000
Some atomic collision experiments lead to ions having identical q/m ratio, as well as average velocity, so that standard electric and magnetic analyzers are not able to identify them separately.

Fault Identification of Broken Rotor Bars in Induction Motors Using an Improved Cyclic Modulation Spectral Analysis

open access: yesEnergies, 2019
Induction motors (IMs) play an essential role in the field of various industrial applications. Long-time service and tough working situations make IMs become prone to a broken rotor bar (BRB) that is one of the major causes of IMs faults.
