In previous work [27, 26] the author defined a notion of CSP-like operational semantics whose main restrictions were the automatic promotion of most τ actions, no cloning of running processes, and no negative premises in operational semantic rules. He showed that every operator with such an operational semantics can be translated into CSP and therefore has a semantics in every model of CSP. In ...

The paper proposes a diagnostic method using possibility theory. According to possibility theory, fuzzy set A on a set of possible causes U, B on possible symptoms V, and a fuzzy relation R on U ́V could be understood as possibility distributions pU(ui), pV(vj) and a conditional possibility distribution pV1⁄2U(vj1⁄2ui), respectively. In this paper, we define diagnosis as a problem to obtain poss...

In this paper, we purposed a new method in modeling the uncertainty data based on the theory of fuzzy sets and the interpolation B-spline model curve. The uncertainty data firstly defined by using fuzzy number concept and fuzzy relation by defined them in real data form. The existed coefficient control of interpolation B-spline basis function is substituted with the fuzzy data points(FDPs) whic...

A fuzzy preference relation is a powerful and popular model to represent both individual and group preferences and can be a basis for decision-making models that in general provide as a result a subset of alternatives that can constitute an ultimate solution of a decision problem. To arrive at such a Þnal solution individual and/or group choice rules may be employed. There is a wealth of such r...

A fuzzy bipolar relation is a relation defined by a fuzzy bipolar condition, which could be interpreted as an association of a constraint and a wish. In this context, the extension of the relational division operation to bipolarity is studied in this paper. Firstly, we define a bipolar division when the involved relations are crisp. Then, we define, from the semantic point of view, several form...

Rough set is approximate representation of a crisp set. Rough set theory provides an approach to approximation of sets that leads to useful forms of granular computing. Several applications have revealed the need to extend the traditional rough set approach. A special place among various extensions is taken by the approach that replaces the relation based on equivalence with a tolerance relatio...

Topological relations between geographic objects are among the most important kinds of relations to manage in Geographic Information Systems (GIS). However, it its very expensive in storage space to keep these relations explicitly stored. Therefore, the relations are usually not directly stored, but they are inferred from the geometry of the objects. Furthermore, the inference of the topologica...

On 17th March 1909 a boy, Dhamram, aged 12 yeai's, was brought to dispensary for treatment at 9 a.m. History of the case.?The boy had been to mohuwa picking where he saw a snake hidden under the dried leaves of the tree. In attempting to point out the snake to his friend he was bitten on the dorsum of the light hand at about 8-80 a.m. The snake had been killed immediately after the boy was bitt...
