Supervised machine learning enables complex many-to-many mappings and control schemes needed in interactive performance systems. One of the persistent problems in these applications is generating, identifying and choosing input output pairings for training. This poses problems of scope (limiting the realm of potential control inputs), effort (requiring significant pre-performance training time)...

to increase agricultural crops’ quality and to minimize losses in the final product and used energy during the drying process, major drying system parameters should be continuously controlled. precise control of such parameters is attained by using automatic control systems. to optimize the overall dryer efficiency in a forced convective solar dryer, a controller was designed, constructed a...

A ZigBee based collision avoidance system for railways has been proposed in this paper. The Train Anti-Collision System (TACS) has four sub centers namely, Train Subsystem, Station/Control Center Subsystem, Signalling Post Subsystem and Level Crossing Subsystem. A safe distance of 1 Km has been given for braking between the trains in case of collision distance. Based on the studies, it has been...

از آغاز فراگیر شدن راه آهن در سطح دنیا، مشخص شد که کنترل قطارها تنها با تکیه صرف بر قابلیتها و مهارت لکوموتیوران می تواند حوادث ناگواری را به دنبال داشته باشد. حتی با فرض اینکه لکوموتیوران بدون خطا باشد، به علت محدود بودن دید و طولانی بودن خط ترمز امنیت قطار به طور کامل تضمین نمی شود. بنابراین نیاز به روشهایی که بتوانند این مشکل را حل یا بهبود بخشند کاملا احساس میشد. از نخستین روشها می توان به ...
