To decrease the computational complexity and improve the search capability of quantum-inspired evolutionary algorithm based on P systems (QEPS), a real-observation QEPS (RQEPS) was proposed. RQEPS is a hybrid algorithm combining the framework and evolution rules of P systems with active membranes and real-observation quantum-inspired evolutionary algorithm (QEA). The RQEPS involves a dynamic structure...
In the optical voltage sensor based on first order electro-optic effects, the half-voltage of electro-optic crystal is one of the key factors influencing the input-output characteristic of sensors. With relative analysis of the electro-optic modulation mechanism, LiNbO3 crystal is chosen to set up the measurement system of half-voltage, measurement is done on half-voltage. Theoretical calculation...
In this paper, a type of sensor for the non-contact monitoring of lightning and switching overvoltage in power grid is presented. It is designed based on Pockels effect and stray-capacity coupling theory. Double-crystal structure is utilized to restrain the unwanted influence caused by natural birefringence. The transmission of the data is achieved by optical fibers which are immune to the electromagnetic...
This aim of this paper is to research on culturing marine algae with high efficiency. Using microalgae Isochrysis Galbana as a model organism, a rapid growth regularity of microalgae in 4.5-L bioreactor was discovered under optimized culture condition, namely, specific growth rates of microalgae from the fourth day to the seventh day at maximum phase (631∼905×104 cells·mL−1·day−1). Accordingly, a...
To improve the local search capability of quantum-inspired evolutionary algorithm based on P systems (QEPS), a memetic algorithm based on P systems (MAPS) was proposed. MAPS is a hybrid algorithm combining the hierarchical framework and evolution rules of P systems with real-observation quantum-inspired evolutionary algorithms (rQIEA) and local search methods (LS). In MAPS, rQIEA is employed in elementary...
In this paper, a quantum-inspired evolutionary algorithm based on P systems (QEPS) is used for radar emitter signals to promote the application of membrane computing. QEPS combines the framework and evolution rules of P systems with the chromosome representation and evolutionary mechanism of quantum-inspired evolutionary algorithms (QIEA). With good global search capability and rapid convergence,...
To enhance the local search capability of quantum-inspired evolutionary algorithm, a novel memetic algorithm based on real-observation quantum-inspired evolutionary algorithms (MArQ) was proposed. MArQ is a hybrid algorithm combining QIEA with local search techniques. In MArQ, QIEA was used to explore the whole solution space and tabu search was employed to exploit the neighboring domains of the searched...
Service grid can provide us an environment to distribute tasks to executors around the world. Since there exist time zone difference and different working calendar systems for independent organizations, there will be some organizations are on-duty while others are off work at a specified time point. Therefore, the time factors can play an important role for job optimization scheduling in service grid...
