 Abstract

In the present experimental investigation, the parametric optimization method using Taguchi’s robust design is proposed for Plano milling machining of alloy steel SA387 & mild steel IS2062 with coated cemented tungsten carbide tip tool. In this paper, the effects of process parameters like cutting speed, feed rate and depth of cut have been investigated to reveal their impact on material removal rate and surface roughness. The Plano Milling Machine is used to conduct experiments based on the Taguchi design of experiments (DOE) with orthogonal L9 array. The orthogonal array, signal-to- noise ratio (S/N) and analysis of variance (ANOVA) were employed to find the maximum material removal rate and minimum surface roughness. The experimental results showed that that the optimal combination of parameters for surface roughness are at cutting speed of 250 rpm, feed rate of 1.42 mm/rev, depth of cut of 1.5 mm while for material removal rate are at cutting speed of 400 rpm, feed rate of 1.42 mm/rev, depth of cut of 1.5 mm for material SA-387. The Optimum value of the surface roughness (Ra) comes out to be 2.31 μm. While the optimum value of the material removal rate (MRR) comes out to be 18.8x10 -6 mm 3 /min for alloy steel A387.

 Abstract

Ideal utilization of bandwidth, storage room and simple transmission over correspondence channel are vital and testing undertakings in late sight and sound world. One conceivable answer for conquer this components is picture compression, which will be utilized to diminish the capacity limit of pictures furthermore to transmit a picture with restricted bandwidth. It assumes an imperative part to use the bandwidth in a significant way and conservative by reducing the span of picture without debasing the perceptual visual nature of a picture. Here in this proposition we investigated the execution and examination of adaptive wavelet with level dependent thresholding (AW-LDT) based compression techniques for MRT pictures. Experimental analysis has been analyzed using image quality (IQ) metrics such as Peak Signal to Noise Ratio (PSNR), Compression Ratio (CR) and Mean Square Error (MSE).

Abstract The present study is to know about the customer opinion on CSR practices. It is treated as a long term strategy for value appreciation rather than service motto. We have undertaken a survey to analyze whether customers are believing in CSR practices . we have obtained astonishing results. Most of the respondents felt that companies really do not want to implement CSR with an intention to serve the people but they are doing it to gain the publicity and increase their brand value. Moreover companies are receiving tax incentives for conducting CRM programme .Most of the respondents felt that there may be number of reasons for practicing CSR by the corporate but ultimately it is the people who are benefited by CSR. So it is sure that social welfare is result of CSR activities. It is certain that brand value is certain to increase by practicing CSR. The main reason behind this is companies gain goodwill reputation and positive word of mouth through CSR. In the past companies launch CSR programmes as a part of good intention i.e. to serve the society. But now companies are launching it to increase TRP, GRP which in turn increases profitability and growth. Most of them are of opinion that both the society and companies are benefited by CSR. Society is benefited by their welfare programmes through CSR.

In the present modern wireless communication world, OFDM technique plays an important role in the transmission of multiple signals simultaneously over a single transmission path. OFDM is the good choice for multipath propagation systems. But, this multi carrier modulation technique is suffering with a PAPR problem due to the addition of number of narrow orthogonal sub-carries at OFDM transmitter. This PAPR problem leads to power inefficiency in RF section of the transmitter. To reduce this PAPR in OFDM system, numbers of techniques are proposed and implemented. In this paper we done analysis of different PAPR reduction techniques of OFDM systems and compared their PAPR values through simulation results.

 Abstract

In a ZVS single full bridge inverter with dynamic load with THI PWM is employed. The THIPWM (Third Harmonic injection Pulse Width Modulation) generates more voltage as compared to traditional SPWM. The ZVS THIPWM is evolved from the double-frequency THIPWM by adding gate drive to the auxiliary switch. The ZVS condition is analyzed and the circulation loss of the resonant branch is optimized by adjusting the energy storage in the resonant inductor. The reverse recovery of the body-diode of MOSFET is relieved and ZVS is realized for both main and auxiliary switches. The filter inductors are significantly reduced with higher switching frequency. The design guideline of resonant parameters and the implementation of ZVS THIPWM with dynamic load in MATLAB software are given with graphical representation and reports.

 Abstract

Franchising is an arrangement where one party (franchiser) grants another party (franchisee) the right to use its trademark or trade-name as well as certain business systems and processes, to produce and market a good or service according to certain specifications. The franchisee usually pays a one-time franchise fee plus a percentage of sales revenue as royalty, and gains immediate name recognition, tried and tested products, standard building design and decor, detailed techniques in running and promoting the business, training of employees and ongoing help in promoting and upgrading of the products. For examples some of the largest franchise in the world which are deemed as supersized franchise brands are McDonald’s, 7-Eleven, KFC, Subway, Burger Kind, Hertz, Ace Hardware and Circle K. Until now, research on franchising has been lacking in India. However, India was one of the first Asian countries to develop numerous franchise units. Previous franchising research indicates that qualitative studies are not sufficiently used in this field. Therefore, it was decided to interview franchisees in order to better understand how and why people choose franchise rather than other forms of business. The purpose of this exploratory/descriptive quantitative study is to examine the viability of various franchisee models prevailing in the market. For this research the researcher has selected a sample size in the city of Chennai.

 Abstract

An unmanned aerial vehicle (UAV), commonly known as a drone is an aircraft without a human pilot aboard. Wing bracket plays a major role in the transferring of loads from the wing structure to the fuselage. Bracket members secured respectively to the end of the wing at a forward or aft location, and to the aircraft fuselage form with a clevis pin a clevis connection with the clevis pin projecting through the bracket members. Especially in the UAV wing bracket need to transfer a high load, since the wing span of the aircraft is very high compared to the other. Here wing bracket is designed using CATIA software and then it is analyzed by using NASTRAN &PATRAN software. By analyzing, deflection and stress effects for the load acting on the wing-fuselage bracket can be determined easily. In this analysis piecewise approximation method is been used and for meshing tetra mesh is used.

 Abstract

Water is vital for sustaining all forms of life on earth. Treatment of domestic wastewater before its disposal into the environment was not given much importance until the recent past. This was due to increased contamination rates of surface and ground water sources. Domestic wastewater treatment is becoming even more critical due to diminishing water resources and resulting water scarcity especially during summer in many parts of the country. Aeration is one of the methods which help in the removal of various contaminants present in domestic wastewater. During the past decade, pond aeration systems have been developed which will sustain large quantities of fish and invertebrate biomass. Dissolved Oxygen (DO) is considered to be among the most important water quality parameters in fish culture. Fishponds in aquaculture farms are usually located in remote areas where grid lines are at far distance. Aeration of ponds is required to prevent mortality and to intensify production, especially when feeding is practical, and in warm regions. To increase pond production it is necessary to control dissolved oxygen. Artificial intelligence (AI) techniques are becoming useful as alternate approaches to conventional techniques or as components of integrated systems. They have been used to solve complicated practical problems in various areas and are becoming more and more popular nowadays. This project presents a new design of diffused aeration system using fuel cell as a power source. Also fuzzy logic control Technique (FLC) is used for controlling the speed of air flow rate from the blower to air piping connected to the pond by adjusting blower speed. matlab simulink results show high performance of fuzzy logic control (FLC).
