Mesoscale eddies are important for transporting oceanic energy and matter. We investigated the three-dimensional structure of an irregularly shaped warm eddy using three Chinese underwater gliders and satellite data during May 2015 in the northern South China Sea. The warm eddy lasted for 2 months, remained quasi-steady, and had a mean radius of ~ 70 km from May 10 to May 31. The heat contents observed...
Umbilical can implement the integrated functions of providing power, hydraulic channel for deep-sea underwater equipment, transmitting the chemicals required for the development of oil and gas field, transmitting the control signals from the mother ship as well as data from the underwater equipment sensors. With the development of offshore engineering goes to deep-water day by day, the design, manufacturing,...
Path planning of underwater glider in stronger ocean current field is researched. Firstly, we established the ocean current model and the motion model of the glider in current environment. According to current forecast, the wavefront algorithm and A∗ algorithm were used to get the optimal path respectively. When the time spent on the distance between the start and the destination beyond the current...
Based on the idea of Barro's endogenous economic growth model and the balanced score card, this paper considers the impact of organizational learning on organizational performance eventually reflects in financial affairs, customers, internal business progress, and learning & growth of organization. Financial indexes reflect the organizational performance directly. The latter three aspects are...
Restoration of a power system after a complete blackout is a very complicated problem. Reasonable black-start schemes play a very important role in the fast restoration of the power system. This paper proposes firstly to apply the DEA/AHP method - combining data envelopment analysis (DEA) with analytic hierarchy process (AHP) - to assess and sort the power system black-start schemes. The significant...
A method based on the method of independent component analysis is offered. It can reduce constraint of price regulation information asymmetry in electricity market effectively. Then it is applied to analyze cost of electricity distribution utilities and evaluate the productivity of electricity distribution utilities. As results, the regulation information is compressed effectively and the market information...
