Definitions for heterogeneous congruences and heterogeneous ideals on a Boolean module M are given and the respective lattices CongM and IdeM are presented. A characterization of the simple Boolean modules is achieved differing from that given by Brink in a homogeneous approach. We construct the smallest and the greatest modular congruence having the same Boolean part. The same is established f...

Tourism is becoming an important sector with a great impact on economic development. Tourists form a heterogeneous group of visitors with significantly different spending patterns. This paper addresses the economic importance of a particular class of tourists, viz. those visiting friends and relatives (VFR). After a review of the literature, this paper offers an empirical case study of VFR tour...

Neural Networks are an important class of algorithms used in many machine learning tasks, such as image classification and speech recognition. These algorithms are computeintensive and its users often need heterogeneous acceleration to achieve satisfactory performance. We survey the landscape of heterogeneous acceleration for Neural Networks, comparing three classes of accelerators, GPUs; ASICs...

An important task of multidatabase systems is the integration of existing databases. Database Integration is achieved primarily through the use of generalization. Hence, it is important to develop good tactics for processing queries over generalization hierarchies. This paper defines the class of conjunctive generalization queries, and it describes four tactics for processing those queries that...

In this paper we describe the difficulties we faced to evaluate performance of heterogeneous cluster so that we get reliable performance analysis of a given cluster or in that matter ”cluster of cluster” system. We also describe the options that we thought for such an analysis. We started with homogeneous machines and tried to develop a model to identify the issues that would arise in a general...

In their concept article on page 12, X. Cui, A. P. van Muyden, and J. Dyson, describe state-of-the-art core–shell materials employed as heterogeneous catalysts for a range of sustainable catalytic transformations, focusing the advantages that this intriguing class brings to field.

The nonparametric estimation(NE) of kernel polynomial regression (KPR) model is a powerful tool to visually depict the effect of covariates on response variable, when there exist unstructured and heterogeneous data. In this paper we introduce KPR model that is the mixture of nonparametric regression models with bootstrap algorithm, which is considered in a heterogeneous and unstructured framewo...
