Summary: This paper conducts numerical studies to investigate the hemodynamic effects on the rupture of the middle cerebral artery (MCA) under different working conditions. The findings show that the increase in blood viscosity and velocity leads to higher wall shear stress and increases the risk of aneurysm rupture. The flow pattern inside the aneurysm and the angle of the incoming bloodstream also play important roles in the formation of high-risk regions.

Summary: There is a significant gap between academic research and practical application in power distribution system planning (PDSP). Existing PDSP models in academic research mainly focus on cost as the objective function and have constraints such as power flow equality, voltage limits, and capacity limits. However, these models are rarely used in real distribution system companies. This paper proposes a new feeder planning model for urban distribution networks, considering practical requirements such as load moment, block loads, street layout, network configuration, and the crossing requirement of feeders. The model is solved using mixed integer linear programming and is demonstrated on test and real distribution systems.

Summary: The aim of this study is to investigate the potential region for rupture and hemorrhage inside the MCA aneurysm through the simulation of blood hemodynamics. It mainly focuses on disclosing the impacts of endovascular coiling on blood hemodynamics and the risk of aneurysm rupture. The computational study of blood flow is conducted by solving the Navier-Stokes equations assuming laminar, unsteady, and non-Newtonian flow. The influences of blood hematocrits and coiling porosity are also examined, with results showing limited impacts of blood hematocrit on the maximum OSI in the MCA case.

Summary: This study used computational fluid dynamics to simulate the blood flow in cerebral aneurysms treated with coiling embolism. The results showed that the wall shear stress (WSS) was highest near the neck of the aneurysm, while the oscillatory shear index (OSI) was highest near the dome of the aneurysm. Coiling reduced the OSI but had limited impact on the WSS near the neck.

Summary: In this study, numerical simulations are performed to investigate droplet breakup in an asymmetric T-junction microchannel. The results show good agreement with previous studies, and the effects of capillary number, non-dimensional droplet length, and non-dimensional width ratio on the breakup time and splitting ratio are studied. It is also found that the mass center of the mother droplet is shifted to a wider branch, facilitating the asymmetric breakup in the T-junction microchannel.

Summary: Defining the correct inlet boundary conditions is crucial in computational wind engineering, and synthetic inflow turbulence is a preferable approach due to its cost-effectiveness. This study investigates different synthetic turbulence generator methods and evaluates their performance in wind engineering applications. The results show that most methods produce spurious pressure, except for the Synthetic Eddy Method with the Gaussian shape function (SEM-G), which is found to be suitable for peak pressure prediction with a maximum error of 30%.

Summary: This article introduces a confidence interval based distributionally robust real-time economic dispatch (CI-DRED) approach, which addresses the risk associated with accommodating wind power. By developing a novel ambiguity set based on imprecise probability theory and transforming the original nonlinear dispatch problem into a determined mixed integer linear programming problem, the proposed method effectively balances operational costs and risks. Numerical results on both the IEEE 118-bus system and a real 445-bus system demonstrate the efficiency and effectiveness of the approach.

Summary: This paper studies adaptive optimal control based on sliding-mode surface (SMS) for a class of continuous-time switched nonlinear systems with average dwell time (ADT) using actor-critic reinforcement learning strategy. By developing a specific cost function related to SMS, the original control problem is transformed into finding a series of optimal control policies through AC neural networks. The proposed method is shown to ensure the boundedness of all signals in the considered closed-loop switched nonlinear systems through Lyapunov stability theory.
