Short time power smoothing of a low power wave energy system

IECON 2012 - 38th Annual Conference on IEEE Industrial Electronics Society, 2012
This paper presents smoothing of oscillatory power generated by a wave energy converter (WEC) from sea wave. WEC oscillates in sea wave and an electrical generator connected to it generates oscillatory power of typical period of oscillation of 6 to 10 seconds.

Power-Bandwidth Performance of Smoothed Phase Modulation Codes

IEEE Transactions on Communications, 1981
Constant envelope phase varying sinusoids of the form \sqrt{2E/T} \cos(\omega_{c}t + \phi(t)) are studied, in which the phase function \phi(t) follows some coded pattern in response to data. Power and bandwidth performance are studied for such patterns.

Smoothing of power spectral densities

Proceedings of the 33rd Midwest Symposium on Circuits and Systems, 2002
Power spectral estimates are smoothed using a Kalman filtering approach. The filter is used to segment the power spectral density by separating signal-dominated regions from noise-dominated regions. In doing so, it tends to preserve the fidelity for signal-related spectral peaks while smoothing the segments dominated by the noise.

Smoothing spectral power distribution of daylights

Color Research & Application, 2012
CIE Division 1 entrusted TC 1–74 to investigate the possibility to develop a smooth curve version of the D illuminants. This article investigates the possibility to create such smoothed curves with minimal colorimetric error. Six different smoothing algorithms were investigated; the best method, using a locally weighted regression and smoothing ...

Smoothing Methodologies for Photovoltaic Power Fluctuations

2019 8th International Conference on Renewable Energy Research and Applications (ICRERA), 2019
The escalation of energy demand causes increasing power generation resources. So Worldwide there is a challenge to meet this demand with clean resources. Despite that photovoltaic panels (PV) and wind farms represents a great solution, many voltage and power issues occur.

Distributed estimation of smooth graph power spectral density

2017 IEEE Global Conference on Signal and Information Processing (GlobalSIP), 2017
Stochastic modeling of modern datasets entails the need for accurate descriptions of random phenomena on graphs. In this respect, wide sense stationary (WSS) graph processes have been defined and studied. Fundamental to precise modeling of these processes is the knowledge of the power spectral density (PSD).

A power control game with smooth reduction of SINR objectives

2009 47th Annual Allerton Conference on Communication, Control, and Computing (Allerton), 2009
When rate expectations of users in a wireless network cannot all be satisfied, one choice is to discard some users from the system, in a mechanism called admission control. However, in a data network, users have a certain tolerance to occasional rate outages.

Flying Supercapacitors as Power Smoothing Elements in Wind Generation

IEEE Transactions on Industrial Electronics, 2013
This paper presents a capacitor-clamped three-level inverter-based supercapacitor direct integration scheme for wind energy conversion systems. The idea is to increase the capacitance of clamping capacitors with the use of supercapacitors and allow their voltage to vary within a defined range.

pH regulation and buffering power in gastric smooth muscle

Pflügers Archiv, 2001
Intracellular pH can have profound effects on tissue function, but little is known about how pH is regulated, buffered or affects the function of gastric smooth muscle. As the pH of gastric myocytes may alter with pathophysiological disturbance of the gastric lining, or reduction in blood flow to the stomach, these parameters were investigated ...

Wavelet power spectrum smoothing for random vibration control

IEEE Transactions on Industrial Electronics, 1999
This paper compares the wavelet power spectrum smoothing method with the Welch method in the random vibration control algorithm of an electrodynamic shaker. Practical results show that the wavelet smoothing method improves the control algorithm performance significantly.
