Abstract :

In Modern times need for wideband applications has increased. In recent years there have been many research works are going on in the design of antenna system as it is the main source for any communication system. The horn antenna is widely used in the transmission and reception of RF(Radio Frequency)microwave signals in areas of wireless communications, also used in electromagnetic sensing, nondestructive testing and evaluation, radio frequency heating and biomedicine. Horn antennas have many advantages such as they are simple to build, provide very good directional performance and show excellent peak power handling capability.  Since horn antennas do not have any resonant elements they operate at wide range of frequencies and have a wide bandwidth. Moreover, they serve as a universal standard for calibration and gain measurements of other antennas. This paper highlights the design and fabrication of a pyramidal horn antenna and simulate of its parameters using MATLAB. The materials used for fabrication of proposed horn antenna is steel. The designed antenna has a gain of 10dB operating at 950MHz. Simulation and comparison of developed antenna with the available antenna were done by using MATLAB software.

Abstract :

Today, there is a necessity to build structures which are economical and last for long. The buildings constructed with earth substance without stabilization, deteriorate quickly in bad weather. Compressed stabilized earth block (CSEB) is an alternative building block among the Engineered brick products. These are non pollution, eco-friendly and the construction tends towards green building. Stress-Strain characteristics and mechanical properties are required for effective and economical design. These values vary due to percentage difference in the ingredients in soil at different locations. Here, the structural properties of  stabilized block masonry in cement mortar 1:3 and 1:5 are evaluated under compressive load in vertical direction. fb of CSEB is  9.587 MPa, E: 1550  MPa and µ :0.242.

Abstract :

This paper demonstrates the idea for globalization of small and medium enterprises (SMEs) using product recommendation based on user behaviour and user location. E-commerce platform is fast emerging as a new trend in global trade and SMEs should use this medium to get direct access to the world markets. As SMEs play an important role in exports, manufacturing and employment generation, there is a need to address their issues related with product selection, regulations, intellectual property rights and standards. This research paper will provide easy and smooth way to help SMEs to get the benefit of e-commerce and globalize to international market. In this paper we are going to propose a marketing strategy that will help the customer to get updates about the products which are not available at their location. This paper proposes a recommendation approach in which we will collect the user location and based on that location we will perform data mining and find the products which are not available at the customer’s location.

Abstract :

Performing accurate relative measurements of sample’s activities using a Hyper Pure Germanium detector (HPGe) necessitates the use of calibration standards. However, standards with similar characteristics like those of the measured samples are not usually available. This work aimed at studying the effect of variation in chemical compositions of measured samples on the accuracy of the gamma analysis used hyper purity germanium (HPGe) detector-based spectrometers. The Monte Carlo simulation technique is used to obtain the detector response due to four different standard soil samples. The samples were assumed to be identical except for chemical compositions and slight variations in densities. The simulation process involves the modeling of a HPGe detector for which the pulse height tally “F8” is calculated at different common gamma ray energy lines using the MCNP5 Code for the four samples. The analysis covered gamma energies ranged from 46.5 up to 1764.0 keV. The results showed that the effect of soil's chemical compositions is less than 0.5% for gamma energy greater than 186.2.0 keV.

Abstract :

The flow problem of Magnetohydrodynamic three-dimensional Casson fluid past a porous linearly stretching sheet is investigated analytically. The flow governing equations are reduced to a set of nonlinear ordinary differential equations using the similarity transformations and solved using an efficient and suitable mathematical technique, the differential transform method (DTM), in the form of convergent series, by applying  Pade approximation and the results are validated using Runge-Kutta-Fehlberg Numerical Method. DTM-Pade proves to be an efficient method in solving the Non-linear Differential Equations.  By increasing the non-Newtonian  fluid parameter the fluid reduces to the Newtonian Fluid is illustrated using graphs. It is also clear that the Casson fluid parameter, stretching parameter, Hartmann number and porosity parameter increase with increase in the velocity profiles of the fluid.

Abstract :

This study presents an experiment for examining the degradation and failure of local sharp-dented 6061-T6 aluminum alloy tubes submitted to cyclic bending. The dent depths of circular tubes were considered from very trivial to approximately 0.6 times the tube’s wall thickness. The moment-curvature response revealed an almost stable and closed hysteresis loop. The dent depths had almost no influence on the loop configuration. The ovalization-curvature behaviour demonstrated an asymmetrical and ratcheting trend along with the number of bending cycles. Furthermore, the deeper dent depths led to larger ovalizations. The relationship between the controlled curvature and the number of bending cycles required to ignite failure on a log-log scale displayed five nonparallel straight lines for five different dent depths. Finally, an empirical formula was introduced to simulate the relationship between the controlled curvature and the number of bending cycles required to produce failure. As a result, the experimental and analytical data were found to agree well.

Abstract :

The high-speed catamaran unmanned craft is taken as the research object. A comprehensive optimization mathematical model with rapidity, maneuverability and stability as the objective function was established. The genetic algorithm and particle swarm optimization algorithm were used to optimize the calculation respectively. Then, select the better ones and the algorithm was used to calculate the sensitivity of the five main variables (propeller diameter, pitch ratio, speed, speed, and body spacing) and the effects of different weight assignments on the objective function were discussed. The calculation results show that the particle swarm optimization algorithm is superior to the genetic algorithm. The propeller diameter is the most sensitive variable among the five variables. When the rapidity weight is 9/5, the maneuverability is 4/5, and the stability is 25/36, the equation Constraint satisfaction is best.

Abstract :

In this work the prediction of rain is based on  (a) Time Series method (b)  Fast Fourier Transform method , (c) the average of the two methods , and (d)  modification of the average method by including a random factor.  This factor which is less than one modifies the average value. In these methods, historical rain data of Vidarbha from 1987 to 2018 are selected for projection. These methods take into account the trends in rain pattern also. The forecast is being made in month of February much before the Monsoon season  starts in June. This forecast  makes known that there will be more rainfall than the 32 year average. This early forecast can be useful to the farmers for planting crops, and city governments for making arrangements for water supply.

Abstract :

David and Lang developed a mathematical model (SIR) i.e Susceptible-Infective-Recovered, for the spread of infectious in a given population over a time. The model gives a reasonable and sound results. However, some more realistic factors have not been accounted for in their model. These realistic assumptions will give better understanding of the modelling epidemics if included. Therefore, this paper is proposed to include some of these assumptions to improve the SIR model. We provide a number of contributions by incorporating the assumptions to enhance the analysis of the spread of diseases under different conditions. We have classified these conditions into four and provide experiments to each of the condition. We further provide a numerical scheme for the modified model and simulated the scheme using Visual Basic (VB) to test the model’s accuracy. The results show that the modified model proved to be more efficient than the existing SIR model. However, due to the inclusion of new assumptions to the existing model, the modified model shows faster decrease in infected population and high recovery rate than the existing SIR model. Moreover, we also investigate the reproductive ration, stability analysis, equilibrium points of the model, the Jacobean and the eigenvalues of the model.

Abstract :

The cart-inverted pendulum system is one of the classical experimental systems that fully converges the complex properties of nonlinear control problems. It represents a class of real world systems such as two-wheeled mobile robots, pendubots, missile launchers and many more. The problems associated with it are always challenging topics in the field of control systems. This paper presents a novel technique to control this system stabilizing at a vertical upright position, its unstable equilibrium point. Simulation and experimental results will show a better performance of the proposed controller in comparison with Quadratic Optimal Regulator method under disturbance and change in mass.
