The versatile ability of MZV(MULTI ZONE VEHICLE) to run at any place for specific requirements makes this MZV more creditable in a variety of applications such as stairs-climbing, snow-filled areas, on-road, off-road etc. resulting in reduction of human effort, stress and load of working. Its efficient mechanism provides its ease to perform several functions with optimum results. Multi-Zone Vehicle-999 has been designed especially for handicapped people to reduce their efforts of working. This Paper deals with how efficiently Multi-Zone Vehicle-999 can climb the stairs along with its versatile functionality.
Extractive desulfurization is an alternative for other desulfurization processes due to its certain merits such as less expensive and green. In single stage extractive desulfurization, low level of sulfur (< 50 ppm) in liquid fuel is not achieved. Hence multistage extractive desulfurization is preferred for deep desulfurization (< 50 ppm). In present paper various outlook of multistage extractive desulfurization using ionic liquids has been presented. Feasibility of ionic liquids for multistage extractive desulfurization of liquid fuel with respect to various process parameters has been discussed. Also the extraction mechanism and regeneration along with process consideration has been reviewed.
Electro Chemical Discharge Machining (ECDM) is a well-known process commonly used for machining of non-conducting materials. The current work aims at studying the material removal rate (MRR), tool wear and surface finish of micro-channels machined on borosilicate glass using electro chemical discharge machining (ECDM) under different parametric conditions. Two sets of experiments were conducted. Through one set of experimentation, an optimum voltage value was found which was used for further experimentation by varying the concentration of electrolyte. The throughout study was carried out on a comparative evaluation criteria, both with the presence and absence of an electrolyte stirrer.
In the present scenario, the dimensional accuracy and surface roughness of casted complex shape products have become a critical issue to reduce machining cost in terms of time, price and scrap materials. So, different types of casting processes have been introduced. One of the important casting process is Investment Casting Process with Expandable Polystyrene Pattern, instead of wax pattern. In this casting process, the shell is made by decomposition of Expandable Polystyrene pattern with the application of heat. During the foam removal process, several problems have been created such as bending, expansion, distending and crack of the shell. In this paper, Zirconium Flour and Mullite sand (Aluminium-Silicate) have been introduced as coating materials with different ratio, with binder as Sodium Silicate and Potassium Silicate. Twelve samples have been prepared and the densities and viscosities of each sample are calculated. Twelve shells are also generated. For selection of best shell material composition, Analytical Hierarchy Process (AHP) is used. Sample 7 has the best result. Also, Potassium Silicate is found better than Sodium Silicate as binder, to reduce distending of shell, cracks, etc. and to increase surface finish and strength to weight ratio of shell.
Wire Electric Discharge Machining (WEDM) is a specialized machining process capable of accurately machining parts with varying hardness, complex shapes, which have sharp edges that are difficult to machine using mainstream machining processes. This process is used to make intricate shapes with the help of a wire. Aluminum alloy 6063 is used as a work piece and performance analysis is done to find out the significant control factors for aluminum alloy 6063 by using one factor approach at a time. In this paper effect of various parameters like pulse on time, pulse off time, servo voltage, peak current, water pressure, wire tension, wire feed on cutting rate has been investigated while machining on aluminum alloy 6063 using one variable at a time approach. Experiments show the response for different parameters on WEDM.
There are numerous methods available for the identification of isomorphism and distinct mechanism. According to various researchers their method is easy to use and reliable but every method has some limitations. In this paper author studies among existing methods which are already available in literature. And an effort is being made to compare some important methods from the point of view of various attributes like reliability, simplicity, capability, time and applicability etc. to detect the best method for identification of isomorphism and inversions (distinct mechanism) of a kinematic chain. These methods are based on rating according to above attributes and on a scale of one to five. Highest ratings among these methods are considered as best method.
