Instantaneous frequency estimation and localization
(
Elsevier Inc.
, 2016 , Book chapter)
In many applications, a critical feature of a non-stationary signal is provided by its instantaneous frequency (IF), which accounts for the signal spectral variations as a function of time. This chapter presents methods ...
Detection, classification, and estimation in the (t, f ) domain
(
Elsevier Inc.
, 2016 , Book chapter)
Several studies involving real-life applications have shown that methods for the detection, estimation, and classification of nonstationary signals can be enhanced by utilizing the time-frequency ((t,f)) characteristics ...
A dynamic prognosis scheme for flexible operation of gas turbines
(
Elsevier Ltd
, 2016 , Article)
The increase in energy demand has led to expansion of renewable energy sources and their integration into a more diverse energy mix. Consequently the operation of thermal power plants, which are spearheaded by the gas ...
Multiple comparator classifier framework for accelerometer-based fall detection and diagnostic
(
Elsevier Ltd
, 2016 , Article)
There are a significant number of high fall risk individuals who are susceptible to falling and sustaining severe injuries. An automatic fall detection and diagnostic system is critical for ensuring a quick response with ...
On dual peak detection UWB receivers in noise and interference dominated environments
(
Elsevier GmbH
, 2016 , Article)
We propose the use of a non-coherent dual peak detection architecture for ultra wideband (UWB) receivers. To benchmark our proposed architecture, the performance of non-coherent UWB receivers based on single peak, dual ...
Theory and design of high-resolution quadratic TFDs
(
Elsevier Inc.
, 2016 , Book chapter)
The quadratic time-frequency distributions (TFDs) introduced in the previous chapter represent the majority of traditional time-frequency ((t,f)) methods used in practical applications that deal with nonstationary signals. ...
Multisensor, multichannel, and time-space processing
(
Elsevier Inc.
, 2016 , Book chapter)
This chapter presents time-frequency (t,f) methods suitable for multichannel signal processing using multisensor and time-space processing methods. The topic is covered in seven sections with relevant cross-referencing.

A Neural Field Theory for Loss of Consciousness: Synaptic Drive Dynamics, System Stability, Attractors, Partial Synchronization, and Hopf Bifurcations Characterizing the Anesthetic Cascade
(
Elsevier Inc.
, 2016 , Book chapter)
With the advances in biochemistry, molecular biology, and neurochemistry there has been impressive progress in understanding the molecular properties of anesthetic agents. However, there has been little focus on how the ...
Time-frequency and instantaneous frequency concepts
(
Elsevier Inc.
, 2016 , Book chapter)
This chapter provides an extended in-depth treatment of the material described in Chapter I. It focuses on the precise description of the key concepts and formulations needed to formally describe time-frequency (t, f) ...
Time-frequency diagnosis, condition monitoring, and fault detection
(
Elsevier Inc.
, 2016 , Book chapter)
This chapter aims to further illustrate the (t,f) approach by selecting a few key generic applications of diagnosis and monitoring. The topic is represented by seven sections.
One key application is electrical power ...
