Batch Di e-Hellman key agreement schemes are described, motivated, and analyzed for security and e ciency.

The effects of ultrasonication of corn slurry, on particle size distribution and enzymatic hydrolysis was studied for the dry-grind mill ethanol industry. Two independent ultrasonic experiments were conducted at a frequency of 20 kHz; in batch and continuous systems. The ground corn slurry (33% m/v) was pumped at flow rates 10-28 L/min in continuous flow experiments, and sonicated at constant a...

In this work, perlite was used as a low-cost source of Si and Al in the synthesis of sodalite zeolite using hydrothermal synthesis method. Cu2O nanoparticles were coated on a bed of sodalite zeolite and used as an adsorbent for removal of diazinon from aqueous solutions. To analyze the process, a significant variable .i.e. removal efficiency (%) of diazinon and three dependent parameters as the...

As reverse osmosis (RO) desalination capacity increases worldwide, the need to reduce its specific energy consumption becomes more urgent. In addition to the incremental changes attainable with improved components such as membranes and pumps, more significant reduction of energy consumption can be achieved through time-varying RO processes including semi-batch processes such as closed-circuit r...

the purpose of the current research is investigating the phenylalanine removal by using magnetic nanoparticles (fe3o4) from water samples. the effect of ph, contact time and phenylalanine concentration on phenylalanine adsorption efficiency by magnetite nanoparticles are studied in a batch system. transmission electron microscopy (tem), x-ray diffraction patterns (xrd) and fourier transform inf...

The batch scheduler is an important system software serving as the interface between users and HPC systems. Users submit their jobs via batch scheduling portal and the batch scheduler makes scheduling decision for each job based on its request for computing sources, i.e. core-hours. However, jobs submitted to HPC systems are usually parallel applications and their lifecycle consists of multiple...

The study of scheduling algorithms for parallel tasks in a grid computing context either neglects local reservation systems which manage parallel resources, either suppose that they use a First Come First Served strategy, or the experimental model does not handle parallel tasks. In this report, we describe an API built in the grid simulation tool Simgrid. It offers core functionalities to simul...

This paper describes a modeling and analyzing method for batch sequential control systems by using colored Petri net (CPN) model. For this purpose, we propose systematic procedures to create CPN model from a various information based on ISA S88, i.e., master recipe, equipment information and batch schedule. To examine the effectiveness of the proposed method, we applied it to a two-step polymer...

Despite recent advances, grid and P2P systems remain difficult for many users to bring to real-world applications. One difficulty is the lack of schedulers for such systems. In this work, we consider the allocations of jobs to resources using batch mode methods. These methods are able to provide fast planning by exploring characteristics of distributed and highly heterogeneous systems. In evalu...

The recently developed Q-PI approach for quality control of linear continuous systems is extended to non-linear batch systems. The new control law contains proportional and integral terms with which the operators are intimately familiar. It is shown that control quality may be improved or costs reduced, consistent with the process specifications, by adjusting the tuning constants of the control...
