Time-Frequency Distributions Based on Compact Support Kernels: Properties and Performance Evaluation
(
IEEE
, 2012 , Article)
This paper presents two new time-frequency distributions
(TFDs) based on kernels with compact support (KCS)
namely the separable (CB) (SCB) and the polynomial CB (PCB)
TFDs. The implementation of this family of TFDs ...
A Resolver Angle Estimator Based on Its Excitation Signal
(
IEEE
, 2009 , Article)
A resolver generates a pair of signals proportional to the sine and cosine of the angular position of its shaft. A new low-cost method for converting the amplitudes of these sine/cosine transducer signals into a measure ...
Operational modeling of multistream heat exchangers with phase changes
(
Wiley Subscription Services, Inc., A Wiley Company
, 2009 , Article)
Multistream heat exchangers (MSHE) enable the simultaneous exchange of heat among multiple streams, and are preferred in cryogenic processes such as air separation and LNG. Most MSHEs are complex; proprietary and involve ...
Adaptive and Predictive Control of Liquid-Liquid Extractors Using Neural-Based Instantaneous Linearization Technique
(
WILEY-VCH Verlag GmbH & Co.
, 2006 , Article)
Nonlinearity of the extraction process is addressed via the application of instantaneous linearization to control the extract and raffinate concentrations. Two feed-forward neural networks with delayed inputs and outputs ...
Dynamic behavior of mixer-settlers
(
Wiley Subscription Services, Inc., A Wiley Company
, 1990 , Article)
A mathematical model has been developed to simulate and predict the dynamic behavior of liquid extraction counter current operations in mixer-settler units. Murphree efficiency has been included in the model. The behavior ...
Developing Engineering Learning Objects Online Portal with LabVIEW and an Open Source Web Content Management System
(
ASEE
, 2009 , Article)
Learning objects (LOs) are independent chunks of knowledge normally used for instructional or learning purposes. LOs are normally reusable in the sense that they can be adopted and adapted for various learning and instructional ...
Estimating the number of components of a multicomponent nonstationary signal using the short-term time-frequency Rényi entropy
(
Springer
, 2011 , Article)
The time-frequency Rényi entropy provides a measure of complexity of a nonstationary multicomponent signal in the time-frequency plane. When the complexity of a signal corresponds to the number of its components, then this ...
Robust human silhouette extraction with Laplacian fitting
(
Elsevier
, 2014 , Article)
Human silhouette extraction has been a primary step to estimate human poses or classify activities from videos. While the accuracy of human silhouettes has great impact on the follow-on human pose/gait estimation, it has ...
Boost inverter-based HVDC transmission system with inherent blocking capability of AC side contribution during DC side faults
(
Elsevier Ltd
, 2014 , Article)
Semiconductor advancements in the past three decades have positioned the voltage source converter-based HVDC (VSC-HVDC) solution as a practical and popular alternative to its line-commutated converter high voltage DC ...
Mathematical model for predicting sludge accumulation in septic tanks based on operational parameters: effect of hydraulic mixing
(
John Wiley & Sons, Ltd.
, 2015 , Article)
Reporting sludge accumulation in septic tanks as a constant rate is no longer accepted, and there is a need for a model that predicts sludge accumulation in septic tanks taking into consideration the continuous consumption ...
