We derive coupled nonlinear Schr"{o}dinger equation (CNLSE) for arbitrary polarized light propagation in a single-mode fiber. We introduce a basis of trans... DG Singh,Louw,JJ &Amp,... - IEEE Global Telecommunications Conference 被引量: 17发表: 2003年 Quantum-beat analysis of the rotationa...
atrunature® Grape Seed & Resveratrol now provides timed-release action in an easy-to-take tablet. That means you take ONLY one tablet for sustained benefits every day. Just take it and forget it until the next Omega-3 fatty acids may help maintain and support trunature®葡萄种子& Resvera...
Other external factors also affect the variation of the heart-rate with various frequency components. The heart-rate variability (HRV) has been used as an index for the heartbeat variation, but it represents the variation caused by a large number of factors through a single measure, since it ...
Nutritional epidemiology aims to link dietary exposures to chronic disease, but the instruments for evaluating dietary intake are inaccurate. One way to identify unreliable data and the sources of errors is to compare estimated intakes with the total ene
Depending on the parameters, those systems have a highly non-stationary nature such as exponential growth of amplitude, vibrato, tremolo, and beat (periodic modulation of frequency and amplitude), etc. In this presentation, we will propose an exact mathematical technique for estimating the parameters...
frequency questionnaire, which asks individuals to recall frequencies of intake of various foods over protracted periods. Shorter-term instruments used to identify detailed dietary intake require individuals to estimate and record the amount of food that they are eating (for example, food intake diaries...
biological and acoustics. For example, the human heartbeat has been modeled by Van der Pol equation with large\(\varepsilon\), thereby establishing a close analogy between the heartbeat mechanism and relaxation oscillators. It represents a nonlinear system with an interesting behavior that arises na...
As for timing synchronization in NB-IoT systems, a lot of research has been done. In [17], an effective method is proposed to reduce the complexity of NB-IoT cell search by splitting narrowband secondary synchronization signal (NSSS) generation formulas. In [18], frequency diversity (FD) ...
Abstract: This paper presents an algorithm structure for an active noise control (ANC) system based on an improved equation error (EE) model that employs the offline secondary path modeling method. The noise of a compressor in a gas station is taken as an example to verify the performance of...
Equation-based modeling is one of the great strengths of COMSOL Multiphysics. The ability for you to easily access the equations describing the physics you are working with, and adding or manipulating them as you see fit, dramatically opens up the realm of possibilities that you can achieve thr...
