91. Since heating power is symmetric for each half cycle of applied voltage, the principle component of this hum is twice the line frequency (and even harmonics of the line frequency). 92. A 3D model similarity matching algorithm based on spherical harmonics descriptor is proposed in this paper. 93. Calculatoins of bore show that the acoustic power is radiated mainly from finger holes for fundamental wave and mainly from the open end of bell for higher harmonics. 94. In an electrical network, unbalanced and harmonic currents generated by nonlinear and unbalanced loads can cause harmonics and unbalanced voltage. 95. The seventh fret harmonics pitch should match the fundamental frequency of the open string notes. 96. Two harmonics method is presented for strongly nonlinear dynamic - system. 97. The CPW sub- harmonically pumped diode mixer was used finite ground CPW that can reduce radiation loss, suppress high order harmonics and be more convenient to layout. 98. The approach starts from an analysis of spherical harmonics and finds out a quadratic polynomial form of environment mapping. 99. The researching intention of this paper is to establish a high precise and real time harmonics measuring system. 100. By using the time variant modulation ratio method, the harmonics can be eliminated and a sinusoidal and balanced output voltage or input current is obtained. 101. For the operating power grids, background harmonics can be obtained by field tests. 102. Aiming at the existing problem in harmonics measurement of power system, the paper(presented) a collecting method based on frequency multiplication phase-locked. 103. It usually appears at the RF, blade passage frequency and commutator brush frequency, and their higher harmonics. 104. In the system, an electronic circuit for reducing harmonics of an output signal from a power amplifier in a transmission circuit for a wireless communication device is provided. 105. To measure phase accurately in the presence of harmonics for both noisy input signals, a technique based adaptive bandpass filter (ABF) and the method of interchanging signal channel is presented. 106. These low frequency spectrum lines are basically the harmonics of the rotor shaft frequency and the blade-passing frequency. 107. The Difference in Discrete Harmonics Synthesized pulse Wave form based on FFT and F. T. Spectrums. 108. Usual detectors include rate-line detector that detects the line spectrum at the rate of the chips and carrier detector that detects the line spectrum at the harmonics of carrier frequency. 109. Those who are ready to become Masters of Time will no doubt celebrate this recalibration and will be ready to "ride" the waves of Cosmic Energy that also make one a "Master of Light Harmonics". 110. Derived the formula for computing quadratic harmonics of output current in the single phase unit power factor AC DC converter based on analysis of the circuit module of the equivalent current source. 111. Dynamic harmonic harness and reactive compensation solutions can filter APF output of the high harmonics. High-pass filter with a fixed capacity can realize reactive power compensation. 112. In this paper, two methods for improving the accuracies of the quasi-synchronous sampling harmonics analysis are proposed. 113. In Chapter 4, we discuss a fast prefiltering method for environment maps based on spherical harmonics, which is the analogue on the sphere to the Fourier basis on the line or circle. 114. Based on character of signal in TWACS and harmonic in power system, the digital differential technique can detect the TWACS signal and eliminate the integer harmonics effectively. 115. It provides a modulated clock source that reduces electromagnetic emissions and associated harmonics at the source. 116. The high - frequency harmonics from charge rectifier of storage battery and its suppression means were discussed. 117. The control strategy of adaptive ASLMS-based harmonic cancellation is proposed for eliminating the higher harmonics of acceleration response. 118. Subsequently, the analysis of harmonics can be done in only one period. 119. The development of the ellipsoidal harmonics theory provides means for solving lineared Geodetic Boundary Value Problems(GBVPs) which correspond to an ellipsoid of revolution. 120. At last several Methods : To optimize harmonics are put forward and compared.
