There is an especially strong need in modern large-scale data analysis to prioritize samples for manual inspection. For example, the inspection could target important mislabeled samples or key vulnerabilities exploitable by an adversarial attack. In order to solve the “needle in the haystack” problem of which samples to inspect, we develop a new scalable version of Cook's distance, a classical statistical...
Ship shafting system is the indispensable component of a ship power plant. The primary function of a ship shafting system is to carry out energy transfer from marine engine to propeller, transmit axial thrust produced by the rotation of propeller to the hull, and drive the ship ahead. Vibrational power flow combines the effects of force and velocity amplitudes as well as the irrelative phase angle...
With the increasing consumption of power cable in urban areas, its ampacity becomes a hot research spot. At present, lots of researches about ampacity and temperature field concentrate on one single-core cable. However, pluralities of cables are laid intensively in duct banks for a real power system. Compared to single cable, if several cables are running at the same time, those cables' temperature...
This paper presents a new single image dehazing algorithm using dark channels with global transmission. The existing algorithms using dark channels cannot deal well with the scene in which objects are inherently similar to the atmospheric light and no shadow is cast on them. In order to eliminate the limitation, we use the positive depth of field prior and the global dynamic template instead of local...
Self-healing is the most important characteristic of smart grid, and its content including two parts: self-adjustment at normal state and self-restoration at breakdown state. In distribution network, the objective of self-healing control is supply users ceaseless electric power. The paper proposes a rapid heuristic restoration algorithm to achieve the process from breakdown state to normal state....
With the in-depth development of smart grid, renewable energy, such as wind power, will be an important source of electrical energy, the proportion of renewable resources increase rapidly. Serious problems emerged with large-scale wind power integrating to power grid. The integration of wind generation imports variability and uncertainty to system operation and control. Control center must consider...
The establishment of mathematical model of electric vehicle(EV) driving system combines balance equation of vehicle movement with equation of mechanical characteristics of direct current (DC) motor. Fuzzy PI control strategy optimizes the model and simulates the model with Simulink software. Simulation results show that the mathematical model of EV driving system can reflect operating condition of...
