We applied a multi-class k-nearest-neighbor based text classiication algorithm to the adap-tive and batch ltering problems in the TREC-9 ltering track. While our systems performed well in the batch ltering tasks, they did not perform as well in the adaptive ltering tasks, in part because we did not have an adequate mechanism for taking advantage of the relevance feedback information provided by...

This paper describes a case of integrating Siebel CRM (Customer Relationship Management) with Finnish Red Cross (FRC) training-site application. The main focus is on evaluating a suggested batch-transfer based integration architecture using use case scenarios and Software Architecture Analysis Method (SAAM) method. The batch approach is compared against synchronous web service based architectur...

We investigate performance characteristics of secure group communication systems (GCSs) in mobile ad hoc networks that employ intrusion detection techniques for dealing with insider attacks tightly coupled with rekeying techniques for dealing with outsider attacks. The objective is to identify optimal settings including the best intrusion detection interval and the best batch rekey interval und...

This article would study batch and recursive methods that used in terrain navigation systems. Terrain navigation has a lot ofdisadvantages and so researchers have been studied on different method of aided navigation for many years. Therefore, more types of aided navigation systems were introduced with advantages and disadvantages in terms of practical and theoretical. One of the main ideas for ...

Many interesting computations can be expressed conveniently as data-driven task graphs, in which individual tasks wait for input to be available, perform computation, and produce output. Systems such as DAGMan, Karajan [7, 8], Swift [7, 8], and VDS support this model. These systems have all been used to encode and execute thousands of individual tasks. However, dispatching such tasks directly t...

Scheduling is one of the interesting research fields in batch chemical industries, which substantially differs from that in discrete manufacturing systems. One of the main differences between these two fields is the intermediate storage of materials, which appears in chemical processes. This situation prevents the direct applicability of some of the scheduling techniques (such as Petri nets) us...

Game theoretic analysis of sequencing situations has been restricted to manufacturing systems which consist of machines that can process only one job at a time. However, in many manufacturing systems, operations are carried out by batch machines which can simultaneously process multiple jobs. This paper aims to extend the game theoretical approach to the cost allocation problems arising from se...

The work of this paper contributes to the structural analysis of batch deterministic and stochastic Petri nets (BDSPNs). The BDSPN model is a class of Petri nets introduced for the modelling, analysis and performance evaluation of discrete event systems with batch behaviours. The model is particularly suitable for the modelling of flow evolution in discrete quantities (batches of variable sizes...
