Abstract:
Capital is required for the growth and also for the development of every sector of the economy at large. There are two sources of arranging capital that is internal sources and external source. In the year 1991 India has faced Balance of Payment crisis which force India to open the economy for liberalisation, Privatisation and Globalization. This allows a foreign capital to invest in selected sector. There are various factors which can affect the foreign capital investments like Strong Regulatory System, emerging market, transparent economy etc and this gives scope to Foreign Institutional Investors (FII) to invest capital. Corporate Governance is also considers as one of the factor which can have impact on inflow of capital in equity and debt. Hence there arises a need to find out to what extent FII are related with Corporate Governance of a company. The present study tries to find out the relation of Corporate Governance with FII and also tries to find out the other extraneous variables impact on FII. For the study purpose the secondary data will be collected from respective company’s annual reports of the year 2015-16. CNX Nifty 50 companies are selected for the study. To find out the impact various statistical tool were applied like Correlation Coefficient, Regression model, f-test and z-test

A Markovian inventory integrated policy with inter-demand time as exponential distribution is considered in this paper. This paper presents, a single-vendor and multiple-buyers integrated inventory model for deteriorating items. The model contains the exponential parameter which is unknown and is estimated through MLE and Baye’s under a squared error loss function. The conjugate Gamma prior is used as the prior distribution of exponential distribution. Finally, a numerical MCMC simulation is used to compare the estimators obtained with Expected risk and are shown graphically. The proposed model is formulated and the optimal decisions are obtained by minimising the average total cost of the integrated system. A numerical example is taken to illustrate the developed model. The sensitivity analysis is also carried out for the model with percentage change in the parameters.

Abstract:
The changes observed and evaluated due to the solvent effect of a dipolar protic or dipolar aprotic solvent on the thermodynamic extensive properties of solvolysis of the propionate ester have been found responsible for changes in its biochemical and medicinal properties.With a view to highlight the effect of a polyhydric alcohol (dipolar protic solvent) on the extensive thermodynamic properties of propionate ester, the kinetics of alkali catalysed hydrolysis of ethylpropionate was studied in aquo-glycerol reaction media. From the enhancement observed in G* values with simultaneous decrease in the values of H and S* of the reaction, it is inferred that the organic co-solvent glycerol acts as entropy controller and enthalpy stimulator solvent for alkali catalysed hydrolysis of ethyl propionate. The numerical value of Iso-kinetic temperature of the reaction which comes to be nearly 286.0 (below 300) indicates that there is weak but considerable solvent-solute interaction in the aquo-glycerol reaction media.

Abstract:
The study explored the students’ engagement in the group-based approach and analyzed their perceived advantages and disadvantages in learning mathematics. It employed the descriptive method of research through a researcher-made instrument to collect the learners’ perceptions on the statements describing the positive and negative effects of group-based learning on the grounds of their experience. Three groups of respondents were considered as samples in equal numbers, forty each from the classes of STEM (Science, Technology, Engineering and Mathematics) students in the secondary level, Science major students in the tertiary level, and Mathematics major students also in the tertiary level. All of them were exposed to group-based learning in their respective mathematics classes. Data were analyzed using the weighted mean and t-test for independent samples. Statistical results revealed that majority of the respondents believed that there were more merits than drawbacks when they were engaged with a group. Students’ from different levels and in diverse fields of interest expressed varied opinions on some issues regarding their experience in working with peers. Based on the learner’s perceived beneficial and shortcoming effects of this learning approach, the study offers recommendations which may be considered by the mathematics educators in the design of their instructional plan.

Abstract:
Several energy saving opportunities in the ethiopia ceramics factory are obtained by this research and can be directly implemented in the factory. It is tried to classify some of energy saving options based on cost of implementing them and this is done by estimating the capital cost and annual cost of operation as well as saving that could be achieved by implementing the saving option and by calculating the payback period of the measures. The result of the current research has showed that more saving can be achieved by investing more on identified energy saving opportunities. Energy saving measures identified by the current research like reducing thermal mass of existing kiln cars, installing new modern low thermal mass kiln cars, recovering waste heat from cooling zone of tunnel kilns especially from glost kiln, installing high speed burners in kilns, avoiding dummy firing in tunnel kilns, reducing loss of products at each step of production, applying monitoring and targeting system etc can be implemented with low cost there by resulting in huge energy saving which can pay back the investment cost in less than two years time, for most of them the payback period being below one year. But above all the energy saving opportunity that can make ceramics factory competent in local as well as in world market by greatly reducing its specific energy consumption. This measure will require substantial investment cost and change in process and the reward will be very high; saving of about 50% with payback period of below three years. The major fuel switching opportunities identified by current research and to be applied in Ceramics Factory are mainly focused on switching to cheaper fuels that can be obtained within Ethiopia thereby saving the foreign currency the country expends to import petroleum fuels. According to the researcher this can be achieved by using Ethiopian coal as fuel in spry drier which currently uses gasoil, effectively recovering heat from cooling zones of kilns to supply heat required for drying sanitary wares to save fuel used in boilers to produce hot water for mentioned purpose, and as there is plan that Ethiopia will be commercially producing natural gas in coming six years it is wise decision to switch fuel of kilns from current kerosene to natural gas. This will have multi-benefit as experiences from developed countries shows that they have already done this measure because natural gas is environmentally friendly fuel than other solid and liquid fuels and in our case it will save foreign currency for fuel of kilns when produced in Ethiopia.

Abstract:
The objective of this contribution is to present a numerical simulation method to model the motion of a packed bed in a rotary kiln using object-oriented techniques. The method chosen is the Lagrangian time-driven method and it uses the position, the orientation, the velocity and the angular velocity of particles as independent variables. These are obtained by time integration of the three-dimensional dynamics equations which were derived from the classical Newtonian mechanics approach based on the second law of Newton for the translation and rotation of each particle in the granular material. This includes keeping track of all forces and moments acting on each particle at every time-step. Contact forces depend on the overlap geometry, material properties and dynamics of particles and include normal and tangential components of repulsion force. The resulting equations of particle motion are solved by the Gear predictor–corrector scheme of fifth-order accuracy.The back ground version of DEM and time integration algorithm are developed and implemented into C++ code. The implementation of time-integration algorithm is verified by simple test concerning particle-particle, particle-wall interaction for which analytical expression exist. In this paper particle force due to different material property are investigated.

Abstract:
The instability of the plane interface between two Oldroydian viscoelastic superposed fluids through porous medium in the presence of uniform rotation and variable magnetic field is discussed. The magnetic field, the viscosity and the density are assumed to be exponentially varying. For stable density stratification, the system is found to be stable for disturbances of all wave numbers. The magnetic field stabilizes the potentially unstable stratification for small wave-length perturbations which are otherwise unstable. The long wavelength perturbations remain unstable and are not stabilized by magnetic field. Rotation does not affect the stability or instability, as such, of stratification.

Abstract:
A large quantity of ceramic tiles change into wastage, these waste materials are not reusable and recyclable due to their physical and chemical structure. Using ceramic wastage in concrete production could be an effective measure in maintaining the environment and improving the properties of concrete. The present experimental study deals with the investigation of possibility of using waste ceramic tile in concrete. Waste ceramic tile is the least expensive of all the concrete constituents and is much less expensive than natural aggregates and thus the idea is to replace as much of the natural aggregates as possible to save money and to reduce the amount of disposable wastes, as well, but care has to be taken in order not to weaken the concrete by adding too much ceramic tiles. To do so, first, the ceramic waste tiles are collected and then being grind by a hammer. They are used in concrete as the substitute for coarse aggregates with 0 to 50 percent of substitution with W/C ratio of 0.5. Besides, all other parameters are constant. Then a standard series 18 density tests and compressive strength tests were conducted. The output results obtained from this laboratory program showed reliable data points and promising further research horizons. The optimum value of coarse waste ceramic tile to be used within the concrete mix with a water-cement ratio of 0.5 was determined as about 30%, and the corresponding expected 28-days hardened concrete compressive strength was about 23.2MPa. Also the density of concrete cube decreases as the amount of tile increases. The findings revealed that using waste ceramic tile lead to enhancing the properties of concrete

Abstract:
The knowledge of the maximum depth of scour around such structures is essential from the point of view of safety of these structures; excessive scour can undermine the foundations and lead to the failure of the structure. Alluvial streams are sometimes partially obstructed by hydraulic structures such as spurs, bridge piers, abutments, guide banks etc. In some other cases high velocity sheets of water from spillways and sluice gates flow over loose alluvial material. In all these cases the bed level in the vicinity of the structures is lowered as a result of interaction between the high velocity flow and the loose bed and consequent modification in the flow pattern, such local drop in the bed level is known as local scour. Proper design requires that the foundation be taken down to a level lower than the anticipated level of the scour hole. It has been reported that since 1950 over 500 bridges have failed in U.S.A. and majority of failures were due to scour of foundation material. In the Indian context, such data on number of failed bridges due to scour are not easily available. However it is known that scour has been the matter of concern to the railways, and detailed hydrologic and scour studies have been undertaken by RDSO, Lucknow. Three major reasons for such a concern can be mentioned namely- (i) Inadequate knowledge of scour phenomenon when these bridges were constructed; (ii) these bridges were designed probably for maximum observed flood upto the time of design. However, since flood is a probabilistic phenomenon, floods of higher magnitude of larger return period must have occurred and for which foundation was no designed. (iii) lastly the size of wagons , trucks and their frequency has significantly increased which has increased the load on the bridge

In this paper, we studied the scenario of distribution losses in Haryana due to electricity theft. The electricity board in the state of Haryana is facing financial losses owing to these distribution losses and the main reason for this is the non-technical losses. Distribution losses account for the mismatch between the billed electricity units and supplied units. The major factors which are responsible for distribution losses are system inefficiency, tampering with energy meter, hiding actual installed load, malpractice of electricity theft etc. Social and economic factors like literacy, income, lack of information etc. also affected the distribution losses in Haryana, a rural dominated Indian State. Haryana is an Indian State in which 65.21% of total population lives in the rural areas. In this paper, we analyse the distribution losses based on the data obtained from the distribution company in the northern areas of State (i.e., Uttar Haryana BijliVitran Nigam Ltd.). For indicative analysis, we have chosen Kharkhoda block of Haryana State as the sample area for study of the distribution losses based on the data provided by UHBVNL.

Abstract:
Frequency deviation control is a major issue in a power system. With increase in complexity of the network and frequently changing load, make it more significant issue. For stable operation of the power system within the stability limit, the frequency deviations must be controlled. Controlling frequency by installation of prime mover governor is a very simple mechanism to control the frequency deviations. If the frequency of the system is not controlled within the fraction of time, the stability may be jeopardized. Many intelligent techniques are available in the literature to control the frequency deviations such as fuzzy control, particle swarm optimization and neural network control etc. Fuzzy logic frequency controller is proposed in this paper.
