Data flow graphs are a popular program representation in machine learning, big data analytics, signal processing, and, increasingly, networking, where graph nodes correspond to processing primitives and edges describe control flow. To improve CPU cache locality exploit data-level parallelism, usually process batches. Batchy is scheduler for based packet engines, which uses controlled queuing re...

Batch processes are very common and important in, e.g., the chemical industries. The international standard ISA S88.01 defines the terminology, the functionality and the models for batch control systems. The production specification of how to produce a batch, is called a recipe. This paper shows how High-Level Grafchart, a Grafcet and High-Level Petri net based programming language can be used ...

Abstract Scheduling of processes in mixed batch/continuous plants, due to their hybrid nature can become very complex. This paper presents the Timed Hybrid Petri net (THPN) as a suitable tool for modelling and scheduling of hybrid systems. One of the major benefits over traditional methods is a significant reduction in complexity during problem formulation. A sugar milling plant containing both...

Removal of Fe (II) from aqueous media was investigated using chitosan as the adsorbent in both batch and continuous systems. Batch experiments were carried out at initial concentration range of 10-50 mg/L and temperature range of 20–40˚C. In batch experiments, maximum adsorption capacity of 28.7 mg/g and removal efficiency of 93% were obtained. Adsorption equilibrium data were well-fitted with ...

one of the major obstacles of bt production as a biopesticide is its expensive bioprocess and fermentation. therefore, the objective of the present study was to optimize growth condition and develop a low-cost bioprocess for mass production of a native coleopteran-effective bacillus thuringiensis (bt) strain (kh4) based on agricultural wastes, at incubator and batch fermenter level. preliminary...

a shortcut procedure as quick, easy-to use method for design and simulation of multicomponent batch distillation is used to predict the operating condition of recovering xylene from solvent in an existing batch distillation column in benzol refinery. the procedure can be used to investigate the effect of the operating parameters on the operation of column for three possible modes of batch disti...
