Bidirectional asymptotic structure methods have long been used to solve topological optimization problems, but are prone being stuck in local optimal solutions. To this problem, paper proposed a topology method based on the Bi-directional Evolutionary Structural Optimization and Simulated Annealing algorithm (SA-BESO). First, structural elements of partition encoded by dual encoding, where assigned with density values binary strings. Second, strings crossed mutated, while criteria for adding...
AbstractThis article discusses the experimental investigation of dynamic mechanical behavior polyethylene (PE) foam under shock wave loading. The experiments were conducted using a two-stage light tube, and response was characterized by measuring pressure transmitted through load on specimen sensor cell, respectively. High-speed imaging also used to capture deformation during results show that loading is non-uniform along length influenced presence metal plates inserted specimen. degree...
This paper introduces an improved sequential convex programming algorithm using adaptive non-uniform discretization for the hypersonic entry problem. In order to ensure real-time performance, inverse-free precise based on first-order hold is adopted obtain a high-accuracy solution with fewer temporal nodes, which would lead constraint violation between nodes due sparse time grid. To deal this limitation, developed, provides search direction purposeful clustering of discrete points by adding...
When applying the sequential quadratic programming (SQP) algorithm to topology optimization, using quasi-Newton methods or calculating Hessian matrix directly will result in a considerable amount of calculation, making it computationally infeasible when number optimization variables is large. To solve above problems, this paper creatively proposes method for approximate structural with minimum compliance problems. Then, second-order Taylor expansion transforms original problem into series...
<title>Abstract</title> The mechanisms underlying how cells dynamically remodel membrane phospholipids to prevent phospholipid peroxidation-induced damage and evade ferroptosis, which maintains the physiological function of cellular processes cell survival, remain unclear. Herein, we reported that lysophosphatidylcholine acyltransferase 1 (LPCAT1) played a critical role in ferroptosis resistance by increasing saturation via Land’s cycle, consequently reducing levels polyunsaturated fatty...
Abstract Considering the uncertainty of wind power output and load as well differences in operating characteristics various adjustable resources over different time scales, a multitime scale optimal dispatching model based on stochastic optimization distributed robust is designed for distribution network. Firstly, demand response user side divided into price-based incentive-based load, price elasticity coefficients are introduced to describe it. Then, with minimum operation cost network,...
In this paper, we investigate the synchronization problem of a two-layer network, consisting an information exchange layer and noise diffusion layer, each with different directed topologies. A new stochastic control is proposed conditions for network are derived through Lyapunov method extension algebraic connectivity in graphs. The effect on also considered, it demonstrated simulation example that can induce synchronization. This demonstrates advantages over traditional control. Finally,...
This paper introduces the extrapolated proportional integral projected gradient (ePIPG) method, a newly developed first-order for second-order cone programming problems (SOCP), and its customized implementation to solve 3-DoF powered-descent guidence problem. The ePIPG solvers parse problem parametets automatically fully utilize sparse structure. In addition, different from classic interior-point being only relies on simple algebra operations, example, projection onto convex sets,...
