In the case of limited energy, waste energy and economic loss caused by abnormal electricity consumption should not be underestimated its detection plays an important role. However, also faces many challenges. On one hand, labeled data are difficult to obtain. other building different models for users undoubtedly increases demand burden training. To tackle these challenges, in this paper, we propose a transfer learning based graph convolutional network with self-attention mechanism method...

Kinetic Monte Carlo (KMC) is a widely used method for studying the evolution of materials at microcosmic level. At present, while there are many simulation software programs based on this algorithm, most focus verification certain phenomenon and have no analog-scale requirement, so serial in nature. The dynamic algorithm implemented using parallel framework called SPPARKS, but it does not support Embedded Atom Method (EAM) potential, which commonly metal materials. Metal material - preferred...

Power systems are undergoing a significant change by introducing competition. In market environment, the decentralised decision-making approach should be strongly encouraged so as to use an ‘invisible hand’ achieve efficient equilibrium. However, in current power markets, centralised is still widely used due lack of proper optimal methods, e.g. OPF for managing congestion and setting price. A management spot market, which can also discover price, proposed. this approach, each participant...

Minimally invasive vascular surgery is an important surgical procedure which requires specialized skills to manipulate instruments. However, the insufficient conventional training paradigm of "see one, do teach one" cannot meet urgent need for surgeons. In this paper we present a novel computer-based system aims at helping trainees with acquiring manipulation and gaining simulated experience. This integrates physics model guide wire, 3D vasculature segmented from real patients self-designed...

Abstract Adjusting the trailing edge radius of intake struts may be advantageous in suppressing vibration compressor rotor blades. To explore impact on excitation force and vibration, this study focuses a with struts, fluid calculations were conducted. The revealed that decreasing led to reduction separation near strut’s edge, resulting narrower wake weakened mixing edge. This caused total pressure loss region induced by become more elongated low-frequency component, leading nonlinear...
