Field-programmable gate arrays (FPGAs) can provide an efficient programmable resource for implementing hardware-based spiking neural networks (SNN). In this paper we present a hardware-software design that makes it possible to simulate large-scale (2 million neurons) biologically plausible SNNs on an FPGA-based system. We have chosen three SNN models from the various models available in the literature,...
At first, based on the thought over properly and the modern market competition, the flexible development of Circular Economy has been advocated as a new model of economy development. This development model can solve the externality problems better which have not been solved under traditional model. Then, in this paper, the"3+3"model of the flexible development of Circular Economy has been...
By analyzing the method of present generating test paper, the article represents a method of generating test paper based on genetic algorithm. A mathematical model for generating test paper is built. By putting forward the intercross operator and mutation operator in consistence with the independent coding, an automatic generation system for test paper is realized.
In this paper, an optimization is reported for the determination of time response (Tr) and power (P) of Electric Vehicle. The electric constant of back-electromotive-force, stator d- and q- axes inductances, switching period, battery voltage, stator resistance and torque gear ratio were selected as factors being able to influence the Tr and P. The optimization process was carried out with Doehlert...
This paper proposes a new mathematical method to solve min-max predictive controller for a class of constrained linear Multi Input Multi Output (MIMO) systems. A parametric uncertainty state space model is adopted to describe the dynamic behavior of the real process. Since the resulting optimization problem is non convex, a deterministic global optimization technique is adopted to solve it which is...
Refined Oil demand has great influence on the planning, operation and control of Refined Oil systems. A combined forecasting model based on the principle of gray theories was put forward to optimize Refined Oil demand forecasting models. The example shows that combined gray forecasting model can overcome the disadvantages of individual model, raise the precision.
The modeling and simulation of container terminal logistics system is rapidly developed and widely applied. This paper describes three parts of the modeling and simulation of container terminal logistics system, which includes Logistics system modeling technology, Verification Validation and Accreditation and screening test, and then the research approach and target, the primary coverage and the key...
Aiming at the risks of the real estate appraisal methods of subjectivity, easy handling high dimensional data, Projection Pursuit technique is proposed risk evaluation of real estate to reduce the dimension. And using the PSO algorithm to optimize the projection index function to establish the Projection Pursuit of Real Estate Risk Assessment Model witch is based on PSO. The model is high of objectivity...
