This paper presents a data structure based on Sparse Spatial Selection (SSS) for similarity searching. An algorithm that tries periodically to adjust pivots to the use of database index is presented. This index is dynamic. In this way, it is…

Nowadays, data intensive applications are in constant demand and there is need of computing environments with better intelligent capabilities than those present in today's Database Management Systems (DBMS). To build such systems we need formalisms that can perform complicate inferences,…

An important problem in Mineralogy, is to accomplish an adequate representation of a great amount of data coming from different geological environments, in order to characterize a particular geologic region in terms of its tectonic setting. With such Databases of…

The present experiment attenmpted to evaluate the formation of associations between elements of an odour-flavour compoundpared with a LiCl injection, in rats. The data ob­tained show that the aversion produced to the lacquer thinner odour is greater when this is…

Introduction: The nutritional registries are data bases through which we obtain the information to understand the nutrition of populations. Several main nutrition societies of the world have these types of registries, outstanding the NADYA (Home artificial and Ambulatory nutrition) group…

In this paper the stability of specific quantum control protocols is analyzed through a simu­lation. Two-level quantum systems driven by resonant external fields are studied. The focus of attention are those protocols requiring long sequences of external pulses. It is…

The performonce of an instrumental response, maintained under o fixed-interval schedule, was studied 30 sec., 40 min., 4 hr. and 8 hs.. afterr administering holoperidol, in rats. A marked reduction of operant responding was seen after the first two periods,…
