Summary: An improved hybrid method for constructing a multi-parameter adjustment curve in the time domain is proposed in this paper to generate artificial ground motions that are highly compatible with multi-damping design spectra. The method combines the advantages of the simulated annealing algorithm (SAA) and the time domain adjustment method, and uses SAA to determine the optimal weights of the corrective time histories and adjust the artificial ground motion in the time domain to reduce the fitting error. The method also simplifies the multi-damping design spectra matching problem.

Summary: Mining of upper multilayers in deep coal seams generates cyclic loading-unloading stresses in bottom layers, which improve permeability and enhance coalbed methane gas drainage. Testing showed that permeability increased approximately by 5.8 times after loading-unloading cyclic tests. Different numbers of loading-unloading cycles produced similar fracturing effects, with the largest effect occurring within the effective stress range of 4 to 11 MPa.

Summary: This research validates a numerical model using experimental results and investigates the nonlinear seismic response of stiffness-eccentric structures under varying seismic orientations. The study finds that stiffness-eccentric structures are more sensitive to rotational seismic response, and the rotational response at the stiff edge exhibits more variability than at the flexible edge under different seismic orientations.

Summary: This article introduces a distributed estimator design problem for stochastic Hamiltonian systems under fading wireless channels. The goal of the problem is to design estimators that can estimate the target state of the Hamiltonian system and ensure the stability of the estimation system using fading channels and graph theory. The article provides sufficient conditions for the existence of the designed estimator gain for each sensor and validates the theoretical claims through two examples.

Summary: This article investigates the impact of energy harvesting (EH) on throughput optimization in Industrial Wireless Sensor Networks (IWSNs). By transforming the problem into a convex optimization problem using the successive convex approximation (SCA) approach under limited EH energy supply, a power allocation algorithm is proposed to maximize the network's transmission rate. Simulation results show that the proposed algorithm can maximize throughput under the premise of SINR reliability.

Summary: The study reveals the effects of different mining intensities, cyclic loading and unloading, and pore pressure on gas permeability in a coal mine. The permeability evolution curve can be described by quadratic polynomial equations and split into three stages. Different axial stress paths during cyclic loading and unloading have varying effects on coal permeability, with increased axial and confining pressures decreasing permeability and pore pressure sensitivity.
