The present study is concerned with the investigation of mechanical properties of A713 alloy castings produced by investment casting process using expandable polystyrene as the pattern material and the plaster of paris as the mould material. Experiments were conducted as per Taguchi’s L9 orthogonal array. Castings were made under the constraint of different process parameters like mould firing ...

The concept of "random loose packing" (RLP) has evolved through extensive study of loose packings of spheres, which has resulted in an accepted definition as the loosest packing that can be obtained by pouring grains. We extend this consideration to packings of nonspherical grains (ellipsoids) formed by slow settling in a viscous liquid, and perform a detailed analysis of the structural propert...

The performance of a two stage control design scheme on the control of liquid outpouring and the suppression of liquid sloshing during the outpouring phase of the pouring process is studied for the case of liquid containers carried by manipulators. The designed scheme, that does not require measurements of the liquid’s motion within the tank, combines a partial inverse dynamics controller with ...

Diesel fuel in motion when is transporting by pipes mixing, pumping, filtering, agitating or pouring them from one vessel to another can generate static charges. Also, electricity may occur if the liquid splashes and forms a mist inside tank. Accumulation of can, under certain conditions, be discharge ignite flammable/explosive atmosphere. Ignition hazards discharges eliminated controlling gene...

We investigate the capacity of various ISI channels with additive white Gaussian noise. Previous papers showed a minimum Eb/N0 of −4.6 dB, 3 dB below the capacity of a flat channel, is obtained using the water-pouring capacity formulas for the 1 + D channel. However, these papers did not take into account that the channel power gain can be greater than unity when water-pouring is used. We prese...

In this paper predictive model for Metal Matrix Composite (MMCs) has been developed with the use of Artificial Neural Network. Stir casting process has been used to fabricate the fly ash based AL-6063 particulate MMC. The hardness of fly ash based AL-6063 MMC is taken as output variable, however fly ash(FA) percentage of reinforcement in MMC, stirring speed of stirrer and pouring temperature of...

To accurately pour drinks into various containers is an essential skill for service robots. However, drink pouring a dynamic process and difficult to model. Traditional deep imitation learning techniques implementing autonomous robotic have inherent black-box effect require large amount of demonstration data model training. address these issues, Explainable Hierarchical Imitation Learning (EHIL...
