This article describes an expert system, COT-XPERT, developed for controlling insects and diseases affecting cotton crop as well as system for Rice Stem Borers (RSB) simulation. The system works in two parts. The first part addresses the issues of efficient use of knowledge for RSB problems and...

A significant characteristic of ubiquitous computing is the need for interactions of highly mobile entities to be secure: secure both for the entity and the environment in which the entity operates. Moreover, ubiquitous computing is also characterised by partial views over the state of the...

Neural networks are currently finding practical applications, ranging from 'soft' regulatory control in consumer products to accurate modelling of non-linear systems. This paper presents the development of improved neural networks based short-term electric load forecasting models for the power...

We consider parallel, identical machine scheduling problems where the jobs are subject to precedence constraints, release dates, and the processing times of jobs are governed by independent probability distributions. The objective is to minimize the expected value of the total weighted...

An independence system is a family I of subsets of a ground set V with the property that any subset of any member of I also belongs to I. The inclusion-minimal sets not in I are called minimal covers. We prove several complexity results related to computation, enumeration, and counting of the...

The object-role model (ORM) data structure can be represented in the unified modeling language (UML) using the five fact encoding constructs: class attribute, association, association class, sub-class and the association qualifier. In the existing literature there exist numerous mappings of how...

In dit artikel worden de 9 UML diagramsoorten in hun onderlinge samenhang beschreven. Als uitgangspunt voor deze beschrijving worden de modelleringsconstructies en de modelsoorten uit Kenniskunde gebruikt. Het artikel laat verder zien wat de essentiële diagramsoorten in UML zijn en in welke...
