A novel energy‐based approach for merging finite elements
International Journal for Numerical Methods in Engineering, 2010AbstractA novel approach for merging two intersecting finite elements is presented and demonstrated. The solution mimics concepts from biology and uses principles rooted in continuum mechanics.The problem of attaching (or merging) two coincident finite elements is common when using the plastering technique as part of the advancing front method.

Wavelet transform approach to energy based spectrum sensing
2012 20th Signal Processing and Communications Applications Conference (SIU), 2012The demand for the frequency spectrum is increased everyday which is a natural and limited source. With many new wireless services provided, wireless communication systems grow rapidly, and increasing the demand for spectrum. Cognitive Radio (CR) is proposed as a revolutionary solution to the conflict between increasing spectrum demand and finite ...

Energy-based approach to power transfer system analysis
Proceedings of the 40th IEEE Conference on Decision and Control (Cat. No.01CH37228), 2002This paper presents a new theoretical approach to energy-based power system analysis for multibus power transmission systems. On the basis of mechanical analogy, an exact energy integral expression is derived for lossy multibus systems through rigorous energy analysis.

Augmentation for Synthetic Vision Displays – An Energy Based Approach
SAE Technical Paper Series, 2000<div class="htmlview paragraph">To provide information about the position and orientation of the aircraft relative to the required flight path, several experimental synthetic vision display formats include a depiction of this path by means of a so-called highway-or tunnel-in-the-sky, sometimes augmented with a position predictor.

An energy based approach to undervoltage load shedding
Fuel and Energy Abstracts, 1995Abstract A novel effort to apply Lyapunov's energy methods towards developing an energy based load shedding scheme in order to alleviate voltage instability is presented. An ‘absolute’ energy function is derived which eliminates the need to calculate the unstable equilibrium points (UEPs) and thus saves a considerable amount of computation time.

Wavelet and energy based approach for PVC detection
2009 International Conference on Emerging Trends in Electronic and Photonic Devices & Systems, 2009This paper describes a wavelet and energy based technique for the detection of ventricular premature arrhythmic beats in Electrocardiogram (ECG) that are of great importance in evaluating and predicting life threatening ventricular arrhythmias. Premature Ventricular Contraction (PVC) can be seen in ECG as abnormal wave shape of the QRS complex.

Energy-based approach for flight control systems design
Automation and Remote Control, 2013We consider the fundamentals of the energy-based approach to spatial motion control. The resulting energy balance equation establishes quantitative relations between all energy sources and consumers in the system of objects "flying vehicle--thrust system--external environment." We establish the structure and further modification of an energy-based ...

Energy-Based Approach for Determining Flow Number
Journal of Testing and Evaluation, 2010Abstract The Asphalt Mixture Performance Test (AMPT) is being used in research and is nearing completion to be adopted by highway agencies for evaluating the performance of asphalt concrete mixtures. The implementation of Superpave volumetric mixture design has occurred in nearly all state agencies in the United States.

An Energy-Based Approach for Fatigue Crack Growth
Key Engineering Materials, 2006A fatigue crack growth model under constant amplitude loading based on the total plastic energy dissipation per cycle ahead of the crack was proposed. With the energy balance concept, the crack growth rate was correlated with the total plastic dissipation per cycle, and the total plastic dissipation per cycle was obtained through 2-D elastic–plastic ...
