Simultaneous Scheduling of Machines and AGVs in Flexible Manufacturing System with Minimization of Tardiness Criterion

AbstractOptimum Automated Guided Vehicles (AGVs) operation plays a crucial role in improving the performance of Flexible Manufacturing System (FMS). One of the main elements in the implementation of AGV is task scheduling. This will enhance the productivity, Minimize delivery cost and optimally utilize the entire fleet. This enhance article Deals with Binary particle swarm Vehicle Heuristic Algorithm (BPSVHA) for simultaneous Scheduling of machines and AGVs adopting Rebust factor function and minimization of mean tardiness. The method is found to provide better solutio

Sporulation of Pyricularia spp. in culture. effect of some aromatic compounds

The effect of L-tyrosine, DL-phenylalanine, shikimic acid and chlorogenic acid on sporulation was studied with six isolates of Pyricularia from different gramineous hosts. In general, the isolates from cultivated gramineae sporulated better than the isolates from the wild grasses. The effect of the compounds on sporulation varied with the isolate. Possible genetic differences among the isolates are invoked to explain the results

Sporulation of Pyricularia spp. on detached leaves of gramineae and in media supplemented with leaf extracts

Except for the isolate fromS. italica, all other isolates of Pyricularia sporulated best on detached injured leaves ofT. vulgare andS. italica as compared to their natural host leaves in light. The observed results are ascribed to heterokaryosis and production/selection of sporulating biotypes rather than to the stimulation of sporulationper se of the isolates by special pre- or post-inoculation compounds in the detached leaves

Effect of some phenolic compounds on sporulation and growth of Pyricularia spp

Sporulation of Pyricularia isolates were generally depressed by most of the phenolic compounds under the experimental conditions. However, many of the compounds tended to induce conidial formation in the otherwise non-sporulating isolate from B. mutica. Caffeic acid and guaiacol for the isolate from O. sativa, coumarin for the isolate from E. coracana and cinnamic acid for the isolate from P. repens were stimulatory for sporulation. As judged by their growth response, the isolates from O. sativa and B. mutica tolerated a wider variety of phenols than the isolates from L. hexandra and P. repens. The isolates from E. coracana and S. italica showed an intermediate response

Radioclimatology over Southern India

7-12Radioclimatology over southern India is studied and the results are discussed. The refractivity gradient is found to be maximum during premonsoon months in the coastal areas. Incidence of super-refraction is found to be maximum during April-May while it is minimum in the months of December and January. High refractivity gradients are found to be associated with temperature inversions or isothermals and with very high vapour pressure gradients
