In 1958 - Claude Berge introduced the domination number of a graph which is used to protect the single vertices. But in 2011 Duygu Vargor and Pinar Dundar initiated the medium domination number of a graph which is utilized to protect the pairs of vertices in a graph.
In a graph every vertices u, v ∈ V should be privileged and it is essential to scrutinize how many vertices are proficient of dominating both of u and v. We compute the total number of vertices that dominates all pairs of vertices and evaluate the average of this value and call it "the medium domination number" of graph. The medium domination number of G is the minimum cardinality among all the medium domination sets of G.
We prove the main result by two-dimensional induction method. First we are manipulative the medium domination number of J1,3. Then we are calculating the medium domination number of Jm+1,3 and Jm,n+1. Finally we are getting the medium domination number of Jm,n. By using this method we can proficient to observe how many pairs of vertices are dominates in the Jahangir graph Jm,n.
In graph theory, there are many stability parameters such as the connectivity number, the edge-connectivity number, the independence number, the vertex domination number and the domination number. In this paper, we obtained the bound of the medium domination number of Jahangir graph Jm,n.

The income velocity of money measured as the ratio of GDP at current market prices to money stocks - M1 and M3 - is found to display the characteristics of random walk during 1950-51 to 1992-93. Accordingly, effort has been directed towards searching for an appropriate functional specification for velocity, which accounts for influence of institutional structural and Socio-demographic changes presumed to affect the velocity behaviour. The empirical results derived from alternative specification of velocity equations reveal that failing to take the cognisance of institutional, structural and Socio-demographic variables may produce an upward biased income elasticity of demand for money. Hence, this study arrived at the conclusion that the virtual decline in velocity when real income rises may be taken to suffer from the errors of ignored variables which act as potential shifters of demand for money.

This study investigates the significance of dispersion between the growth rate of some weakly separable monetary asset groups and that of their corresponding monetary aggregates, arising out of non linearity in aggregation. As the aggregates are derived from the Divisia quantity index number the relevant dispersion measures used in the analysis are their second moments. The empirical evidence show that the commonly employed statistical tests - the Granger causality test and the information content test in which both the aggregates and their corresponding dispersion measures appear as arguments, do not require the incorporation of the latter, implying that there is no distributional effect of component assets on the macro behaviour of the aggregates under consideration. Hence, this evidence is attributed to the fact that the Divisia index can track even a non-homogeneous aggregator function and remains appropriate even for changing taste and technology of consumer preference over time.- Selection of Flywheel Material using Multicriteria Decision Making Fuzzy Topsis

Flywheel is used to store rotational energy and subjected to more stress and strain. The selection of material have a vital role in the fabrication of flywheel. In this paper we are using Multi Criteria Decision-Making Fuzzy Topsis tool for selecting the material for flywheel. As per the literature review best suitable 5 materials (Carbon steel 1065, Alloy steel AISI 4340, Maraging steel 18ni, Alloy steel AISI E9310 and Stainless steel) are taken into consideration for selection and with the help of decision makers 5 material properties (Density, hardness, young’s modulus, bulk modulus and poison’s ratio) are chosen for analysis. Weightages are provided by 3 decision makers and averaged for analysis. As per the analysis maraging steel 18ni chosen for the fabrication of flywheel and the least material will be carbon steel 1065. In future more suitable materials and properties will be chosen for analysis which will provide more accurate results and the same method can be applied for selection of materials for other applications.Keywords

The non-biodegradable wastes have been increasing widely day by day. These wastes not only cause harm to the environment and its resources, but also they have an adverse impact on the human health causing a number of health problems. In order to control this issue, a number of approaches have been done and carried out by the hosts. In the present article, we are discussing this issue taking into consideration certain factors and strategies. The factors of waste disposal were identified to be human health, waste reduction, sustainability, cost effective and environmental benefits using the disposing strategies such as landfills, incineration, energy transform, reuse and recycling. The nonbiodegradable wastes include plastics, construction wastes, metal scraps, rubber tyres, man-made nylons, polyesters, glass, cable wires, cellophane, CDs, DVDs, processed wood, styrofoam, aluminium cans and bottles. The survey was carried out using the Fussy Topsis Method, which is a multi-criteria decision making optimization tool. It helps us in making the best choice out of the available options. The results obtained revealed that recycling is the most efficient method, whereas the landfill is an unpleasant option of solid waste management.Keywords

This study examines the extent to which the Reserve Bank of India has sterilised its intervention in the foreign exchange market. We have estimated a monetary policy reaction function and inferred that the sterilisation of official intervention in the foreign exchange market is partial for the sample period 1975-76 to 2000-01. The evidence for a sub sample spanning April 1994 to July 2001, describing the period of market based exchange rate regime, indicates that the sterilisation is more active. However, the positive trend in exchange rate and continuous accumulation of foreign exchange reserve have led us to conclude that the RBI's direct intervention in the foreign exchange market has been mainly for the purpose of building up reserves apart from stabilising the exchange rate. This suggests that if the RBI's direct intervention in the foreign exchange market has the twin objectives of stabilising exchange rate and building comfortable foreign exchange reserves then the exchange rate stability must be supplemented by indirect monetary policy measures.- Intuitionistic Fuzzy Nano Topological Space: Theory and Applications

In automobile industries, usage of unconventional machining is increased due to their precision and accuracy. This research work is planned to upgrade the Wire Electric Discharge Machining (WEDM) process parameters by considering the impact of discharge current, pulse on time, pulse off time and servo speed rate. Tests have been led with these parameters for the measurement of metal removal rate and surface roughness for each of the trial run. This information has been used to fit a quadratic numerical model. Predicted information has been used as a graphical representation for demonstrating the impact of the parameters on chose reactions. Predicted information given by the models has been utilized as a part of an ideal parametric mix to accomplish the unrealistic yield of the procedure. Response surface method with grey relational analysis has been utilized for enhancement. The ideal value has been checked to the predicted value from the confirmation tests.Keywords
