Optimal path planning and smooth trajectory are critical for effective navigation of mobile robots working towards accomplishing complex missions. For autonomous, real time extended operations robots, the capability needs to be executed at edge. Thus, efficient compute, minimum memory utilization key parameters that drive successful operation autonomous robots. Traditionally, solutions focus on developing robust algorithms which compute/memory intensive. Bidirectional-RRT(Bi-RRT) based have...
The composition and properties of blast furnace slags greatly affect the productivity quality hot metal produced. Viscosity is an important physical property slags, strongly influenced by chemical composition, structure temperature. Experimental measurement slag viscosity requires high temperature equipment time consuming. Therefore, parameters are used to identify trends in as function composition. Limited information available for High Alumina Blast Furnace Slags, since much open...
AbstractAbstractBlast furnace operation is a complex phenomenon; maximising productivity requires balance of burden characteristics. Meeting the targets optimum sinter strength and minimum slag volume matter concern for high alumina (2·0–2·1%) iron ore fines. To achieve reduced MgO in may be maintained by addition coke breeze. However, associated increase fuel rate during sintering raises FeO content. The effects increasing lowering on softening melting behaviour materials have been assessed...
The standard free energy of formation alumina, , has been determined in the temperature range 1350°–1550°C, by studying reaction
More than 80% of the high grade chromite ores are fragile and tend to form fines during their handling. In order utilise these ore fine, in ferrochrome production, agglomeration is necessary. present study, direct sintering presence coke breeze has been carried out, which does neither require further grinding ( − 10 mm) nor binder. It uses suitable fluxes as heat source raise temperature up 1600°C produces a semifused mass (20% molten phases) with good strength. The developed sinter showed...
The present study reports unidirectional laminar flow of ferrofluids between parallel plate channels under the action a homogeneous magnetic field. applied field is found to uniquely modify local velocity distribution and reduce effect both adverse favorable pressure gradients. We find that it possible control separation by varying strength within certain range also discuss magnetization relaxation time scale volume fraction solid particles on phenomenon. Finally, we propose an analytical...
Multi-robot systems, working collectively to accomplish complex missions beyond the capability of a single robot, are required for wide range applications such as search-and-rescue, precision agriculture and industrial automation. The collective behavior multi-robot system is governed by its continuous interactions with physical environment, inter-robot information exchange, intelligent decision making. Energy-efficient performance, size, weight scalability key sensor, compute,...

Lump lime and iron ore are generally used in the basic oxygen furnace as flux cooling material, respectively. Owing to high melting point, poor dissolution property, fines generation tendency, hygroscopic nature of lump lime, delay process operational complexities encountered. On other hand, charging creates slag foaming. In order alleviate above problems utilize waste materials, fluxed lime–iron oxide pellets (FLIP) containing oxides (10%–40%) were prepared subsequently strengthened with...
