针对电力系统经济负荷分配这一典型的非凸、非线性、组合优化问题,提出一种将基于自适应权重更新策略和差分进化的随机变异策略的鲸鱼优化优化算法(ADWOA)相结合。该算法首先在鲸鱼优化算法中引入了自适应权重来提高WOA的搜索能力,使算法能够在早期执行精细的全局搜索,在后期执行精确的局部搜索,加速寻优算法的迭代,同时由于随机变异策略,会再次更新位置。然后从更新的结果中选择最优位置,以加速种群的收敛,并有效...
Motion in a random force field     movement  Gay force field       2015/9/29
We consider the motion of a particle in a random isotropic force field. Assuming that the force field arises from a Poisson field in Rd, d  4, and the initial velocity of the part...
Non-linear modal interactions in the dynamics of a vibrating drop are examined. The partial di!erential equations governing the drop vibrations are formulated assuming potential #ow and incompressibil...
Combined seismological, space-geodetic and numerical studies have shown that the seismicity at subduction zones may be modulated by tides and glacier fluctuations on timescales of 1–100 a, becau...
This study uses in situ measurements collectedfire model WRF-SFIRE. during the FireFlux field experiment to evaluate and improve the performance of the coupled atmosphere
The control of thermal radiation is of great current importance for applications such as energy conversions and radiative cooling. Here we show theoretically that the thermal emission of a finit...
Effective magnetic field for photons based on the magneto-optical effect.
We exploit the unique properties of optical waves in nanophotonic structures to enhance the capabilities for active control of electromagnetic thermal transfer at nanoscale. We show that the near-@...
The goal to achieve arbitrary control of photon flow has motivated much of the recent research on photonic crystals and metamaterials. As a new mechanism for controlling photon flow, we in...
The conventional approach for radiationless interference exploits the interference of evanescent components for the purpose of deep-subwavelength focusing and image formation. As a result, deep subwav...
The concept of a tapered outside diameter coiled tubing(TODCT) system was first presented in 20041). This paper laid out the basic requirements for a TODCT system and the advantages of the TODCT sys...
Sonic Scanner has been recently introduced to the market. This is the first 3D sonic logging tool developed in Japan. It measures sound slowness(1/velocity) of P and S wave along well axis, around we...
We present the analytic calculation of the cross-spectral density tensor of a thermally radiative planar dielectric slab in extreme near-field, intermediate near-field, and far-field...
