Fuzzy蕴涵代数的素MP滤子 总被引:1,自引:0,他引:1
对Fuzzy蕴涵代数(简称FI代数)的滤子理论作深入研究.首先对由非空集合生成的MP滤子的性质作进一步探讨;然后引入素MP滤子的概念并讨论其基本性质,给出了素MP滤子的若干等价刻画,证明了并半格FI代数的素MP滤子定理;最后利用素MP滤子概念时满足条件(S)的并半格FI代数的MP滤子格((L)MP(X),(∩))中的素元进行刻画. 相似文献

A novel method of implementation of frequency encoded logic gates NOT, OR, AND, NOR, NAND, X-OR, X-NOR is discussed. The frequency sources and physical requirements for the implementation are also discussed. The non-linear material (liquid) suitable for these operations to be performed should be of large non-linear coefficient, high reverse saturation absorption, large thermo-optic coefficient and low viscosity. The input controlling beams used to induce non-linearity in the switch are either of frequency υ1 or υ2 and the probe beam is a mixed signal of frequencies υ1 and υ2. Depending on the nature of the controlling inputs the output conditions of the probe can be adjusted to get different logic gates. 相似文献

In this paper a simple all-optical logic device, called Mach-Zhender Interferometer is composed by using a semiconductor optical amplifier (SOA) and an optical coupler. This device is used for generating the logical functions (AND, XOR) and a multiplexer and an Encoder are obtained using this device in Optical Tree Architecture. The simulation of Encoder and Multiplexer is done at a rate of 10 Gb/s and both are simulated for different input logical combinations. Simulations indicate that the device is suitable to operate at much higher bit rate and also for different logical entities. 相似文献

三I推理方法是一种新的模糊推理方法,通过已有的研究成果表明,在许多方面它优于传统的CRI推理方法,它将成为模糊系统和人工智能的理论和应用研究中一个比较理想的推理机制。最近,国外学者提出了一个新的模糊逻辑形式系统,叫做Monoidal t-norm based logics(简记为MTL),已经证明这个形式系统是所有基于左连续三角范数的模糊逻辑的共同形式化。本文基于这类逻辑将三I推理方法形式化,从而在这些逻辑系统中为三推理方法找到了可靠的逻辑依据。 相似文献

The feasibility of controlled ultrafast pumping in the mid IR and the probe of the subsequent intramolecular dynamics is illustrated for vibrational excitation of the two metal carbonyls W(CO)6 and Mn(CO)5Br in solution. Pumping and probing is performed by short, 130 fs, pulses centered at about 2000 cm−1. Frequency resolved measurements of the time delayed probe pulse are performed. Measured two dimensional spectra are fitted by a kinetic scheme that models the vibrational dynamics. Fast relaxation is solvent induced with the solvent acting also as a heat bath. The (several) probe signals in the experiment can be thought of as the response of a finite state logic machine. This suggests that the molecular machine can act as an ultrafast (petaHertz) processor. The number of internal (memory) states of the machine is determined by the number of vibrational states in the kinetic scheme that can fit the observed relaxation. The number of outputs of the machine is the number of the several different available probe signals. It is shown that the machine is massively parallel because in each (sub ps) time step it produces an entire vector as an output and that each component of the output vector is, by itself, a transform over the input. Beyond that, the machine can produce a (finite number of) different output vectors in sequential time steps. 相似文献

本文提出了一种新型的加权抽取模糊逻辑推理模型;旨在既克服运用“max-min”算子带来的信息丢失、封闭性、二义失效和全同失效而难于获得合理的结果的缺陷,又克服了传统加权模糊逻辑扬弃子结论之间逻辑关系的缺陷;达到了既考虑子结论的逻辑关系,又考虑了结论的相对重要程度且不丢失过多信息的目的。文中还给出了较详细的实验结果。 相似文献
