Quasi-dynamic energy flow computation (EFC) has become a critical tool to determine and predict the states of multi-energy system (MES), which helps improve MES’ operation efficiency issues security warning. However, methods in literature suffer numerical problems including fake oscillations, divergence, etc., Also, with increasing dimensions, can be hardly guaranteed due cross iterations betwe...

Control systems need to be able operate under uncertainty and especially attacks. To address such challenges, this paper formulates the solution of robust control for uncertain time-varying unknown time-delay attacks in cyber-physical (CPSs). A novel method deal with thwart on closed-loop is proposed. Using a descriptor model an appropriate Lyapunov functional, sufficient conditions stability a...

The upgraded elastic surface algorithm (UESA) is a physical inverse design method that was recently developed for compressor cascade with double-circular-arc blades. In this method, the blade walls are modeled as Timoshenko beams smoothly deform because of difference between target and current pressure distributions. Nevertheless, UESA completely unstable an intense normal shock, which causes d...

A previously unexplored experimental scheme is presented for generating low-divergence, ultra-dense, relativistic, electron-positron beams using 400 GeV/c protons available at facilities such as HiRadMat and AWAKE CERN. Preliminary Monte-Carlo Particle-in-cell simulations demonstrate the possibility of containing $10^{13}-10^{14}$ pairs sufficiently high densities to drive collisionless beam-pl...

Natural and laboratory ESR dose response curves (DRCs) of [AlO4/h]0 [TiO4/M+]0 were investigated for samples quartz from the Luochuan loess-palaeosol master section, Chinese Loess Plateau. The natural DRCs show a clear divergence above ∼1000 Gy, with much lower D0 values saturation levels observed DRCs, which is in agreement previous study by Tsukamoto et al. (2018). Young (<15 ka) Jingbian – a...

We develop numerical methods for performing efficient Brownian dynamics of col-loidal suspensions confined to remain in the vicinity of a no-slip wall by gravity or active flows. We present a stochastic Adams-Bashforth integrator for the Brown-ian dynamic equations, which is second-order accurate deterministically and uses a random finite difference to capture the stochastic drift proportional ...

The United States shows striking racial and ethnic differences in marriage patterns. Compared to both white and Hispanic women, black women marry later in life, are less likely to marry at all, and have higher rates of marital instability. Kelly Raley, Megan Sweeney, and Danielle Wondra begin by reviewing common explanations for these differences, which first gained momentum in the 1960s (thoug...

Stochastic Structural Stability Theory (SSST) provides an autonomous, deterministic, nonlinear dynamical system for evolving a turbulent mean state. In this work SSST is applied to the problem of understanding the origin and dynamics of roll/streak structures associated with both transition to turbulence and maintenance of the turbulent state. Roll structures in the cross-stream/spanwise plane ...
