The collective processing of multiple queries in a database system has recently received renewed attention due to its capability of improving the overall performance of a database system and its applicability to the design ...
A practical approach to transforming extended ER diagrams into the relational model
(Elsevier, 1987-07)
Constructs for the extended ER model are defined and classified as a basis for transformation into the relational model. Transformation rules are developed for the different possible forms of n-ary relationships among ...
Definability by constant-depth polynomial-size circuits
(Elsevier, 1986)
A function of boolean arguments is symmetric if its value depends solely on the number of 1's among its arguments. In the first part of this paper we partially characterize those symmetric functions that can be computed ...
Parametric analysis of dynamic postural responses
(Springer-Verlag, 1984-12)
A detailed theoretical understanding of postural control mechanisms must be preceded by careful quantification of both the deterministic and stochastic aspects of postural behavior of normal and abnormal subjects under ...
