About the Cover

Engineering is the science, skill, and profession of acquiring and applying scientific, economic, social, and practical knowledge, in order to design, build, and maintain structures, machines, devices, systems, materials and processes. Engineering is a profession aspires to high standards of conduct and recognizes responsibilities to clients, peers, and to society as a whole. It is based on knowledge of mathematical and natural sciences. Engineers recognize that the earth’s supply of materials and energy is not limitless, and they must be concerned not only with utilization of these resources but also with their conservation. Engineering involves seeking solutions that are energy efficient and exploring for new sources of energy to replace those that are being depleted. Engineers seek solutions that are economical. This implies that the benefits of their solutions must exceed the costs. It must exercise care in the management of money, time, materials and other resources. Engineers must objectively evaluate their designs to insure that the positive effects exceed any adverse effects and that, on balance, their solutions are for the public benefit.

Privacy Preserving Data Mining: A perspective

Vaijayanthi N

Privacy Preserving Data Mining (PPDM) addresses the problem of developing accurate models about aggregated data without access to precise information in individual data record. A widely studied perturbation-based PPDM approach introduces random perturbation to individual values to preserve privacy before data are published.

A Study on Effectiveness of Management Games in Personality Development (With specific reference to Management Students)


Vaijayanthi N

Many people still think that personality is related to the physical appearance of a person. If a person is well-built and wearing a good dress it is said that he/she has a good personality. But this is not a rational approach.

A Study on Transformational Leadership in Service Sector

Balasubramanian J, Vaijayanthi N

Over the last decade and a half, the topic areas of transformational leadership in organizational settings have undergone a significant evolution in terms of both theory development and empirical investigations. This study briefly describes the roots of transformational leadership and summarizes evidence of its effects. An exploratory research was conducted to find transformational leadership was a stronger predictor for development of the organization. Theoretical and methodological issues for transformational leadership research in professional organizations are discussed.

A Study on public awareness and perception towards solar energy resource

Vaijayanthi N

All the energy that comes from resources which are naturally replenished is classified as renewable energy. Major sources of renewable energy include sunlight, rain, wind, and tides. There are many sources of energy that are renewable and considered to be environmentally friendly and harness natural processes. These sources of energy provide an alternate ‘cleaner’ source of energy, helping to negate the effects of certain forms of pollution. All of these power generation techniques can be described as renewable since they are not depleting any resource to create the energy. The study concentrates about the public awareness and perception towards the renewable energy with specific reference to solar energy and it gives more importance to sensitize the consumers to embrace and practice of sustainable consumption towards solar energy. Solar energy is the key component of energy independence and clean energy because of the two key facts about solar energy. First the sun is a limitless and completely free natural resource available to everyone in the Earth. Second in one hour the Sun supplies the Earth with enough energy for an entire year. Solar energy is harnessed by the use of solar cells also know as photovoltaic cells. In this research topic survey is conducted to identify the public their interest level towards sustainable consumption towards solar energy.

Construct Synthetic Tissues by 3-D Printer

Anusuya V

The new type of material consists of thousands of connected water droplets, encapsulated within lipid films, which can perform some of the functions of the cells inside our bodies. These printed 'droplet networks' could be the building blocks of a new kind of technology for delivering drugs to places where they are needed and potentially one day replacing or interfacing with damaged human tissues.

REVIEW

Industrial automation based on OpenCV: a review

Hiral Raval Jani

As the name Industrial Automation based on OpenCV suggests that some kind of control in instruments/industrial machines is being done. OpenCV(Open Computer Vision) is the image processing library. We can write programs in any IDEs(Integrated Development Environments) in C/C++ language installing OpenCV library in it. Based on that image processing results we can control or automate industrial machines or any process in industries. We can choose any sequences for that.

An efficient control of BLDC motor using PID controller and genetic algorithm

Selvakumar M, Selvaraj P, Sivaprasath V, Vishnu R, Subramanian R

Brushless DC motors (BLDC) are widely used for many industrial applications because of their high efficiency, high torque, higher speed ranges, noiseless operation and low volume. More advanced controllers are used to manage acceleration, control speed and fine-tune efficiency of BLDC motor. A proportional-integral-Derivative (PID) controller is a generic control loop feedback mechanism widely used in industrial control systems because of its simple structure and easy implementation. The conventional PID controllers are not providing optimum performance under non - linear conditions and parameter variations. The aim of this research is to develop a complete model of the BLDC motor and to design an optimal controller for its control. The Genetic Algorithm is proposed as a global optimizer to find the optimized PID gains for control of BLDC motor.

Novel technique for designing Optical Processors

Anusuya V

Rice University scientists have unveiled a robust new method for arranging metal nanoparticles in geometric patterns that can act as optical processors that transform incoming light signals into output of a different color. Rice's team used the method to create an optical device in which incoming light could be directly controlled with light via a process known as "four-wave mixing."
