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,...
The paper has constructed the mathematical model on the storage location assignment in AS/RS, and then optimized and solved it, performed instance simulation design and analysis on the storage location assignment by means of Flexsim. Finally, we have concluded that the storage location assignment model after optimization would solve the storage location assignment problem in AS/RS effectively and...
This paper puts forth a model of the transportation and inventory integration and optimization problem based on system and optimal theory which we take into account the antinomy relationship of transportation and inventory and the antinomy relationship of inventory and stock-out in supply chain logistics system. We consider that the resources available and the total time of inventory and transportation...
Plastic profiles produced by extrusion die are cooled down and calibrated by calibrators, so it is very important to properly design the cooling system in calibrator for the profile quality. Based on the finite element method (FEM) and the finite difference method (FDM), the numerical simulation of the cooling process is realized for plastic profile within calibrator. The simultaneous shape and topology...

Some key technologies of the mathematical theory and algorithms about...
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...

As the complexity of under the condition of large-scaled resource-constrained multi-project duration optimization problems, it is difficult to give its analysis solution. With the network technology in this paper, taking the minimum number of the multi-project weighted duration as the goal, then establish a mathematical model for the optimization problem. In view of the basic cellular automaton topological...
The process planning and scheduling (PPS) is to determine a solution (schedule), which tells a production facility what to make, when, and on which equipment, to process a set of parts with operations effectively. Multiobjective PPS problems become more complex because the decision maker need to make a trade-off between two or more objectives while determining a set of optimal nondominated solutions...
With respect to the multiplicative complementary judgement matrix, n groups of approximate weight vectors are given by considering the judgement informations in detail provided by decision makers (DMs) in this paper. And some information aggregation operators are used to aggregate these approximate weight vectors according to the credibility degree of alternatives into judgements defined in this paper,...
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...
In order to solve two major bottlenecks of the analog design flow: the time-to-market and the production yield, we introduce in this paper a design tool for measuring the robustness capability of the analog circuit topologies with the guarantee of fulfilling all the design specifications. With this measure, we can describe the feasible subspace by using the set inversion algorithm. A robustness estimation...
The constraints to manage in a telecom splitter design are numerous and according to a given splitter structure, the choice became difficult.

This one carries out the modelling of the electrical circuit configurations, and creates the corresponding computation code, used for simulation or optimisation. The methodology is detailed...
A systematic design methodology for low-noise amplifiers (LNAs) is introduced. This methodology follows a bottom-up approach that employs a multi-objective evolutionary optimization algorithm, which is used at two levels. First, it is used to generate Pareto-based performance models for integrated planar inductors. To do so, an electromagnetic simulator that takes into account the inductor's layout,...
In this paper, it is to apply genetic programming to explore some new chaotic systems. Based on a tree representation, each function in the state dynamical equation of a chaotic system can be well defined. Thus, through the optimization process governed by genetic programming, it is demonstrated that some new potential forms can be determined, for which chaotic systems are obtained by having tuning...
Traffic congestion has been a long-held social problem because of the increasing number of vehicles. In this paper, we apply a pheromone model to a traffic signal control in order to alleviate the traffic congestion. The pheromone model is a tool to communicate among insects (e.g., ants) for their crowd action. In our target problem, the pheromone is strewed by vehicles in a trail across the road...
Wireless Sensor Networks(WSN) is a hot spot of the research of wireless networks currently, the key of achieving efficient transmission business is to control node energy and improve the network lifetime in wireless sensor networks.

In city traffic system We adopt intelligent traffic system. We make use of the tension characteristics of composite-spring-net to solve traffic problems. The tension characteristics are that every route income is more, its residual capacity is smaller, and every route income is smaller, its residual capacity is more. We use the tension characteristics, and use MAS at tempering traffic system choosing...
