Pseudo-BL algebras are non-commutative fuzzy structures which generalize BL-algebras and pseudo-MV algebras. In this paper we study the states on a pseudo-BL algebra. This concept is obtained by using the Bosbach condition for each of the two implications of a pseudo BL-algebra. We also propose a notion of conditional state for BL-algebras.The author would like to thank Laureiu Leutean for his valuable suggestions in obtaining the final version of the paper.  相似文献

Generalized Bosbach and Rie c? an states, which are useful for the development of an algebraic theory of probabilistic models for commutative or non-commutative fuzzy logics, have been investigated in the literature. In this paper, a new way arising from generalizing residuated lattice-based filters from commutative case to non-commutative one is applied to introduce new notions of generalized Bosbach and Rie c? an states, which are called hybrid ones, on non-commutative residuated lattices is provided, and the relationships between hybrid generalized states and those existing ones are studied, examples show that they are different. In particular, two problems from L.C. Ciungu, G. Georgescu, and C. Mure, “Generalized Bosbach States: Part I” (Archive for Mathematical Logic 52 (2013):335–376) are solved, and properties of hybrid generalized states, which are similar to those on commutative residuated lattices, are obtained without the condition “strong”.  相似文献

Rough implication operator based on strong topological rough algebras   总被引:1,自引:0,他引:1  
The role of topological De Morgan algebra in the theory of rough sets is investigated. The rough implication operator is introduced in strong topological rough algebra that is a generalization of classical rough algebra and a topological De Morgan algebra. Several related issues are discussed. First, the two application directions of topological De Morgan algebras in rough set theory are described, a uniform algebraic depiction of various rough set models are given. Secondly, based on interior and closure operators of a strong topological rough algebra, an implication operator (called rough implication) is introduced, and its important properties are proved. Thirdly, a rough set interpretation of classical logic is analyzed, and a new semantic interpretation of ?ukasiewicz continuous-valued logic system ?uk is constructed based on rough implication. Finally, strong topological rough implication algebra (STRI-algebra for short) is introduced. The connections among STRI-algebras, regular double Stone algebras and RSL-algebras are established, and the completeness theorem of rough logic system RSL is discussed based on STRI-algebras.  相似文献

In this paper we proved several theorems concerning the structure of finite dimensional estimation algebras. In particular, under proper technical assumptions, we proved the following: (1) The observation of a filtering system must be linear if the estimation algebra is finite dimensional. (2) All elements of a finite dimensional estimation algebra belong to a special class of polynomial differential operators. (3) All finite dimensional estimation algebras are solvable.  相似文献

We consider the boolean complexity of the decomposition of semi-simple algebras over finite fields and number fields.We present new polynomial time algorithms for the decomposition of semi-simple algebras over these fields. Our algorithms are somewhat simpler than previous algorithms, and provide parallel reductions from semi-simple decomposition to the factorization of polynomials. As a consequence we obtain efficient parallel algorithms for the decomposition of semi-simple algebras over small finite fields. We also present efficient sequential and parallel algorithms for the decomposition of a simple algebra from a basis and a primitive idempotent. These will be applied in a subsequent paper to obtain Las Vegas polynomial time algorithms for the decomposition of matrix algebras over and .  相似文献

In this paper infinitesimal elasto-plastic based topology optimization is extended to finite strains. The employed model is based on rate-independent isotropic hardening plasticity and to separate the elastic deformation from the plastic deformation, use is made of the multiplicative split of the deformation gradient. The mechanical balance laws are solved using an implicit total Lagrangian formulation. The optimization problem is solved using the method of moving asymptotes and the sensitivity required to form convex separable approximations is derived using a path-dependent adjoint strategy. The optimization problem is regularized using a PDE-type filter. A simple boundary value problem where the plastic work is maximized is used to demonstrate the capability of the presented model. The numerical examples reveal that finite strain plasticity successfully can be combined with topology optimization.  相似文献

无线传感器网络中的传感器要把被监测的数据有效地传输到远端的收集器,且其节点的能量有限,为了提高衰落无线信道中无线传感器网络通信的有效性,提出基于有限反馈机会波束的无线传感器网络,基站设置多天线,传感器节点设置单天线,构成MISO系统,在每一时隙基站选择处于峰值状态的传感器节点进行通信。设置反馈门限,当传感器节点的接收信干噪比大于反馈门限时,对信干噪比进行量化,再将量化电平反馈给基站;否则,无需进行量化和反馈。以吞吐量最大化为原则设定最佳反馈门限和量化电平,在瑞利块衰落信道中对系统进行仿真,结果表明:随着节点数的增加,该系统的反馈数可降至传统模拟反馈的1%以下,大大降低了反馈量,提高了系统的效率和节点能量利用率。  相似文献

This research addresses system reliability analysis using weakest t-norm based approximate intuitionistic fuzzy arithmetic operations, where failure probabilities of all components are represented by different types of intuitionistic fuzzy numbers. Due to the incomplete, imprecise, vague and conflicting information about the component of system, the present study evaluates the reliability of system in terms of membership function and non-membership function by using weakest t-norm (Tw) based approximate intuitionistic fuzzy arithmetic operations on different types of intuitionistic fuzzy numbers. In general, interval arithmetic (α-cut arithmetic) operations have been used to analyze the fuzzy system reliability. In complicated systems, interval arithmetic operations may occur the accumulating phenomenon of fuzziness. In order to overcome the accumulating phenomenon of fuzziness, this research adopts approximate intuitionistic fuzzy arithmetic operations under the weakest t-norm arithmetic operations (Tw) to analyze fuzzy system reliability. The approximate intuitionistic fuzzy arithmetic operations employ principle of interval arithmetic under the weakest t-norm arithmetic operations. The proposed novel fuzzy arithmetic operations may obtain fitter decision values, which have smaller fuzziness accumulating and successfully analyze the system reliability. Also weakest t-norm arithmetic operations provide more exact fuzzy results and effectively reduce fuzzy spreads (fuzzy intervals). Using proposed approach, fuzzy reliability of series system and parallel system are also constructed. For numerical verification of proposed approach, a malfunction of printed circuit board assembly (PCBA) is presented as a numerical example. The result of the proposed method is compared with the listing approaches of reliability analysis methods.  相似文献
