A general description of various path-dependent functions is given by using series expansions of Taylor type. Path-integrals and path-tensors are defined as many-components quantities whose values contain complete information on the path. These quantities are considered as elementary path-dependent functions and are used instead of power monomials in ...

Imprecise Functional Dependencies
2009Functional dependencies represent a fundamental concept in the design of a database since they are capable of capturing some semantics of the data strongly connected with the occurrence of redundancy in a database. The development of applications working on fuzzy and multimedia databases has required the extension of the functional dependency notion to

Dependencies in fuzzy databases: functional dependency
Proceedings of 1995 IEEE International Conference on Fuzzy Systems. The International Joint Conference of the Fourth IEEE International Conference on Fuzzy Systems and The Second International Fuzzy Engineering Symposium, 2002Classical and fuzzy functional dependencies, which consist of an important class of constraints, are examined in fuzzy relational databases. The truth value of a proposition expressing a functional dependency is not a binary value even for a classical functional dependency in fuzzy relational databases.

Neuropsychological functioning and alcohol dependence
Current Opinion in Psychiatry, 2005Alcohol dependence is a significant challenge to society and health-care services. The associated cognitive deficits are thought to affect behavioral control, therapy and liability to relapse. The present review demonstrates important new findings.Recent interest focused on compensatory functional circuits, components of executive functioning ...

Functional Dependency and Other Related Dependencies
2005The invention and rise of the relational database starting in the 1960s was accompanied by the remarkable development of canonical design techniques, making it possible to avoid many database designs with unintended bad consequences (Codd, 1970, 1971). These techniques, called “normal forms,” prevent the occurrence of what are called “anomalies.” If a ...
