Abstract This paper explores an idea of Stoic descent that is largely neglected nowadays, the argument valid when conditional formed by conjunction its premises as antecedent and conclusion consequent true. As will be argued, once some basic features our naïve understanding validity are properly spelled out, a suitable account conditionals adopted, equivalence between arguments true makes perfe...

Canonical quantization is a wonderful procedure for selected problems, but there are many problems which it fails. Affine different that has shown can solve canonical cannot. Here, words like succeed and fail to refer whether the results correct or incorrect. This paper offers two simple examples serve introduce affine quantization, compare studies of procedures.

Traditional approaches to temporal databases are either not formal or deal only with static features, considering mainly a single state of the database. The temporal nature of data in temporal databases, however, is intrinsically dynamic, for it deals with the evolution of data.

In this paper we extend the XPath data model and query language to include valid time. XPath is a language for specifying locations within an XML document. We extend XPath’s data model by adding to each node a list of disjoint intervals or instants that represents the valid time. The valid time for a node is constrained to be a subset of the valid time for a node’s parent. We extend the XPath q...
