Application of Fast Dynamic Allan Variance for the Characterization of FOGs-Based Measurement While Drilling

open access: yesSensors, 2016
The stability of a fiber optic gyroscope (FOG) in measurement while drilling (MWD) could vary with time because of changing temperature, high vibration, and sudden power failure.

Improved simulation of lignocellulosic biomass pyrolysis plant using chemical kinetics in Aspen Plus® and comparison with experiments

open access: yesAlexandria Engineering Journal, 2023
The successful use (for performance predictions, in previous work) of process modeling and simulation of fast pyrolysis plants has made these techniques imperative in the design and operation of the pyrolysis plant itself.

Differential Amplify-and-Forward Relaying in Time-Varying Rayleigh Fading Channels [PDF]

open access: yes, 2013
This paper considers the performance of differential amplify-and-forward (D-AF) relaying over time-varying Rayleigh fading channels. Using the auto-regressive time-series model to characterize the time-varying nature of the wireless channels, new weights

Finite-Time Synchronization Between Two Different Chaotic Systems by Adaptive Sliding Mode Control

open access: yesFrontiers in Applied Mathematics and Statistics, 2021
The finite-time chaos synchronization between two different chaotic systems with uncertain parameters and external disturbances is studied. A new and improved adaptive fast nonsingular terminal sliding mode control (ANFTSM) has been designed for a fast ...

From packaging to fast timing simulators

open access: yes2003 IEEE International Symposium on Electromagnetic Compatibility, 2003. EMC '03., 2003
When considering all the steps from packaging to verification of the design one is faced with many challenges ranging from the choice of the proper tools to model the device/interconnect physics, to high level simulations at the timing level. This paper starts by reviewing some of the tools available for extraction of device/interconnect parameters ...

A broadband stable addition theorem for the two dimensional MLFMA [PDF]

open access: yes, 2009
Integral equations arising from the time-harmonic Maxwell equations contain the Green function of the Helmholtz equation as the integration kernel. The structure of this Green function has allowed the development of so-called fast multipole methods (FMMs)
