Efficiency and Slippage in Draw Gears with Flat Belts
This paper presents the measured energy losses in a draw gear with NE22, XH500, LL2, and CFG flat belts. The ranges of torque capacity, slippage occurrence, and transmission efficiency of selected drive belts are also presented.

On transmission efficiency of quantum modulations [PDF]
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]
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]
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.
