As the use of electronic voting systems and e-commerce systems increases, the efficient batch verification of digital signatures becomes more and more important. In this paper, we first propose a new method to identify bad signatures in batches efficiently for the case when the batch contains one bad signature. The method can find out the bad signature using smaller number of modular multiplica...

In this work, we evaluate the benefits of using Grids with multiple batch systems to improve the performance of multi-component and parameter sweep parallel applications by reduction in queue waiting times. Using different job traces of different loads, job distributions and queue waiting times corresponding to three different queuing policies (FCFS, conservative and EASY backfilling), we condu...

The objective of this paper is simultaneous of aerobic and anaerobic process for phosphorus removal from a dairy wastewater. The system consists of a granular sequencing batch reactor (SBR) working under alternating aerobic/anaerobic conditions. In order to analyze the process, four significant variables viz. MLSS, COD/N ratio, aeration time and cycling time and four dependent parameters as the...

At one time, information technology was thought to be best left to technicians so that managers could concentrate on the serious business of management. However, that might have been an effective division of labor only when computers were used solely to automate well-defined administrative functions, such as batch processing of payroll or preparation of summary financial returns. The organizati...

The Distributed Batch Controller DBC supports scienti c batch data processing The DBC dis tributes batch jobs to one or more pools of workstations and monitors and controls their execution The pools themselves may be geographically distributed and need not be dedicated to process ing batch jobs We describe the use of the DBC in a large scienti c data processing application namely the generation...

The Distributed Batch Controller (DBC) supports scientiic batch data processing. The DBC distributes batch jobs to one or more pools of workstations and monitors and controls their execution. The pools themselves may be geographically distributed, and need not be dedicated to processing batch jobs. We describe the use of the DBC in a large scientiic data processing application, namely the gener...

For the conceptual design of countercurrently operated reactive distillation columns, fast methods are needed to estimate potential top and bottom products. The possible column bottom product composition can be determined from the stable singular points of a batch reactive reboiler. In a similar manner the top product composition can be obtained from the stable singular points of a batch reacti...

We examine key convergence properties of the steady-state simulation analysis method of nonoverlapping batch means (NOBM) when it is applied to a stationary, phi-mixing process. For an increasing batch size and a fixed batch count, we show that the standardized vector of batch means converges in distribution to a vector of independent standard normal variates—a well-known result underlying the ...

A batch process is a discontinuous and concurrent process which is suitable for multi-product, small-sized production. The distinctive feature of a batch process is that various decision making processes, such as scheduling, design, operation, etc. are strongly connected with each other. Interaction among these processes is necessary to dynamically and flexibly cope with a variety of unplanned ...

The approach presented in this article is based on the real time simulation of p-time Petri net for the real time scheduling of batch systems. After defining the different kinds of constraints which can exist in a linear hybrid production system, we present the conflict resolution principle used by a token player algorithm at the global coordination level.
