The paper connects the characteristics of a dissipative system, which operates far from equilibrium, a chaotic system , depending upon initial conditions and complexity, which forms from the holistic connection of its parts .Consequent, the human brain, human society and the universe itself are portrayed as dissipative, chaotic and complex. Chaos is everywhere as is complexity. The paper analyzes the aspects of nonlinearity in system dynamics based on the ideas of Ilya Prigogine and attempts to forge a link between the systems discussed . The Second Law of Thermodynamics involving the total increase in entropy is elucidated as being universal and inherent in all events of the universe. The law may be considered as part of the evolutionary tool in the formation of complex organisms, galaxies and life itself. Chaotic phenomena are considered in forming, through bifurcation points, un9predictable yet deterministic complex systems .The universe is strikingly similar in its structure to ...

Over the most recent two decades or somewhere in the vicinity, flow forming has been developing as a metal shaping procedure for the generation of engineering parts in little and medium bunch amounts. One of the most earliest used technique for chip-less development is Metal spinning. Customarily, in this procedure a tubular work-piece is hung on a mandrel and prolonged, through thickness diminishment, by pivotally moving rollers. High exactness, thin walled and tubular segments are customary flow shaped items. The power and force necessities are much lessened as compared to the press forming, due to the incremental process and also at a time just a little volume of metal is deformed. In this paper, impact of roller way and feed ratio on a spun sample's wall thickness and also numerical model of wrinkling failure were done. There was unique blank thickness due to high feed ratio additionally prompt material failure and unpleasant surface wrap up.

Chaotic phenomena are considered in forming, through bifurcation points, un⁹predictable yet deterministic complex systems .The universe is strikingly similar in its structure to the human brain and follows the sequence from dissipative state to complexity and order through chaos .For the Second Law of Thermodynamics to be valid universally, the universe is proposed to be an open system. Furthermore it would be governed by intelligence.

The widespread adoption of particulate metal matrix composites (MMCs) for engineering applications has been hindered by the high cost of producing components of complex shape. Casting technology may be the key to overcoming this problem with stir casting. But the problem arises with stir casting is wettability and porosity. To overcome the problem of porosity a hybrid casting process is needed. So, hybrid stir casting process was developed to produce a silicon carbide particulate aluminum alloy composite. In this paper, the authors have discussed the various parts like Muffle Furnace, Thermocouple, Electric motor Impeller & Stirrer, Crucible, Vacuum pump, Nitrogen gas, and Lifting mechanism of the Hybrid Stir Casting process.
