Self-consistent scattering theory of transport and output characteristics of quantum cascade lasers [PDF]

, 2002
Electron transport in GaAs/AlGaAs quantum cascade lasers operating in midinfrared is calculated self-consistently using an intersubband scattering model.

Performance Prediction of Subsonic Separated Cascades [PDF]

Volume 5: Manufacturing Materials and Metallurgy; Ceramics; Structures and Dynamics; Controls, Diagnostics and Instrumentation; General, 1990
During the design process of fans and compressors, rapid computation of performance characteristics at various operating points is essential. In view of estimating off-design performance, the prediction of compressible separated flow is needed. A method has been developed for predicting such flows in 2-D cascades, with varying blade ...

Adaptive Cascade Generalized Predictive Control

International Journal of Intelligence Science, 2014
Cascade control is one of the most popular structures for process control as it is a special architecture for dealing with disturbances. However, the drawbacks of cascade control are obvious that primary controller and secondary controller should be tuned together, which influences each other.

Colliding cascades model for earthquake prediction [PDF]

Geophysical Journal International, 2000
A wide set of premonitory seismicity patterns is reproduced on a numerical model of seismicity, and their performance in prediction of major earthquakes is evaluated. Seismicity is generated by the Colliding Cascades Model, recently developed by the same authors. The model has a hierarchical structure.

Terahertz quantum cascade laser bandwidth prediction [PDF]

2015 International Topical Meeting on Microwave Photonics (MWP), 2015
Recent research shows that terahertz quantum cascade lasers are well-suited to high speed free space communication. The results of both theoretical and laboratory work indicate the devices are able to deliver bandwidths in the gigahertz to tens of gigahertz range without the burden of relaxation oscillations found in diode lasers.

Novel application of Relief Algorithm in cascaded artificial neural network to predict wind speed for wind power resource assessment in India

Energy Strategy Reviews, 2022
Wind power generated by wind has non-schedule nature due to stochastic nature of meteorological variable. Hence energy business and control of wind power generation requires prediction of wind speed (WS) from few seconds to different time steps in ...

Prediction of Cascading Failures in Spatial Networks

PLOS ONE, 2016
Cascading overload failures are widely found in large-scale parallel systems and remain a major threat to system reliability; therefore, they are of great concern to maintainers and managers of different systems. Accurate cascading failure prediction can provide useful information to help control networks.
