Based on the data of yellowfin tuna Thunnus albacares caught by tuna longline survey sponsored by Agriculture Department's Fishery Observer Programme in the western central Indian Ocean from January to June in 2003 and 2004,the basic biological characteristics of yellowfin tuna were studied.
Based on the data from Observer Program sponsored by Agriculture Ministry and the number of Thunnus obesus captured from China tuna longline fishery in the West-central Indian Ocean between January and June in 2003 and 2004,the reproductive biology of Thunnus obesus captured were analyzed.
Present international environmental law has entitled environmental NGO some rights. Thus environmental NGO can participate in international environmental affairs with the status such as consultative status,observer status,partnership status and "tthe friend of court" status.
Today,China has become an observer of the GPA and independent innovation has become one of our basic national strategies. The research on the international legitimacy of the right that government gives priority to the procurement of their own intellectual property products undoubtedly has important theoretical and practical significance.
The high-gain observer was used to estimate the state of the system.
A sliding mode perturbation observer (SPO) is designed to estimate unmeasurable states and system perturbations that involve system nonlinearities, disturbances and unmodelled dynamics.
It was shown that the processes in the observer based on the desired matrix transfer functions are limited by the possibilities of physical realization and that in the general case the desired processes in the observer are rank-constrained.
Stepwise procedures for choosing state observer controls from high-gain feedback systems are developed.
Linear control in the "object-state observer-controller" loop was considered.
