Comparison of Stiffness of Skin - Simulations vs Experimental
Abstract: Minimally invasive surgeries are the most elusive, yet highly demanded subset of surgeries which requires precise knowledge of the pertinent patient. Compared to conventional surgeries, minimally invasive surgeries are characterized by less pain, low risk of infection, lesser scarring, etc. In the status quo, doctors use intuition through experience to determine the parameters for surgery such as the force required to cut, size of cut, depth of cut, etc. With …

Behavior of Iron Ores During the Sponge Iron Production Process
Abstract: Behavior of natural iron ores with coal from different mines were undertaken to achieve better quality of sponge iron during direct reduction. Iron ore is the raw material used to make sponge iron, which is one of the main raw materials to make steel. 98% of the mined iron ore is used to make steel. The paper gives the introduction about subject. It tells about the need of direct reduced …

Effectiveness of Extensional Damping Using Rubber as Layer
Abstract: Structural damping treatments are free layer damping and constrained layer damping, made of metal and viscoelastic layer combinations which help to reduce vibrations. A free layer damping (FLD) treatment also known as Extensional Damping is formed by applying a coating of a damping material to one side of a structure. The treatment may be symmetric or asymmetric, and applied to beams, plates or shells in bending or in tension. In …

Efficient Conversion of Sponge Iron from Iron Ore-Coal Composite
Abstract: Today India stands as the largest producer of coal based sponge iron using calibrated ore and non-coking coal. Production of sponge iron, via the direct reduction route using rotary kilns, continues to experience significant growth in India. Direct-reduced iron (DRI), also called sponge iron, is produced from direct reduction of iron ore (in the form of lumps, pellets or fines) by a reducing gas produced from natural gas or coal. …

Mathematical Modelling and Comprehensive Review on the Application of Evolutionary Strategies in Design Optimization of Shell and Tube Heat Exchangers
Abstract: This review article presents the application of different evolutionary algorithms which have been utilized for design and optimization of shell and tube heat exchangers in the last decade. The traditional trial and error design approaches can be replaced by such evolutionary algorithms. These evolutionary techniques do not need information of derivatives and hence it can be implemented in various heat exchangers geometry without much complication. Many such EA’s are successfully …

Modification of gating System of Ball Valve Component using Soft-cast Simulation
Abstract: There are two main important considerations in castings are quality of the casting and yielding of the casting due to which scrape of material will reduce. Production of good quality casting mainly depends upon the gating system. In casting process gating and risering system has direct effect on its quality. Generally, many industries follow the trial and error method for casting process which is not economical for foundries for long …
