Space Vector Control Method for PM-BLDC Motor
Several methods have been proposed to eliminate the low-frequency torque pulsations for BLDC motor drives such as Fourier series analysis of current waveforms and either iterative or least-mean-square minimization techniques. Most methods do not consider the flux linkage control, therefore possible high-speed operations are not feasible. In this work, a novel and simple approach to achieve a low-frequency torque ripple-free speed and flux control with maximum efficiency based on dq reference frame similar to the permanent magnet synchronous motor (PMSM) drives is presented. The electrical rotor position is estimated using winding inductance, and the stationary reference frame flux linkages and currents. Moreover, this method also permits to regulate the varying signals. Simple voltage vector selection look-up table is designed to obtain fast torque and flux control. Furthermore, to eliminate the low-frequency torque oscillations, two actual and easily available line-to-line back- EMF constants (kba and kca) according to electrical rotor position are obtained offline and converted to the dq frame equivalents using the new Line-to-Line Park Transformation. Then, they are set up in the look-up table for torque estimation.

Design and Fabrication of Low Cost Additive Manufacturing Machine
This paper describes the design of a 3D printer by reducing its cost to the optimum level. 3D printing technology has become an emerging topic in today’s technological discussion. All over the world companies and individuals are doing experiments by extruding plastics, metal objects for prototyping or their own needs. To satisfy these demands we have developed a machine named as “Additive Manufacturing Machine” based on 3D printing technology. Using this machine user can turn any digital file into a three-dimensional (3D objects) physical products. In this paper, we will look for the additive manufacturing. First, we will define what we mean by this term. Then the methods used in this technology and how we have reduced its cost. Then we will delve a bit into the advantages over conventional methods of manufacturing. We shall observe a lot of applications in today’s world. Finally, the future potential of this technology is outlined.

Big Data Analytics for the Social Security Smart (SSS) Card (National Identity Card) Usage for All Citizens
Discovering the data for the smart card is the collection of data and the development of an application for the social security smart card for the Indian citizen also the design of this application. A smart card is designed is look like typically a type of chip card, is a plastic card that contains an embedded computer chip–either a memory or microprocessor type–that stores and transacts data. The social security card contains only one social security number and the usage of this card is to provide a single card for all the purposes. It can be distributed to all the citizens of India with a Security number. This number is the identity in future for various purposes. With this tracking of a particular person in a particular place is easy.It is used to transact the money only in digital (numbers), not in rupees. It eliminates the money and paperwork.Using this card the wages will be credited to this card.

Role of Information Technology in Human Resources Management
The Internet has changing our lives and the way we interconnect with the others, how we work, how we learn and spend free time, in short, it has changed human society. Information technology (IT) as a set of offered scheme is available for people and organization through hardware mechanism and plays a main role in the growth of human resources. In today’s world, Information technology is the important factor for the growth of human organization and group. This paper encloses a brief overview of the role of information technology in human resources management. Today top CEO knows the power of internet and information technology (IT) mode for reaching organization goal. The utilization of internet and information technology equipment helps not only to complete organization aim but to optimize work evaluation as well.

Laser Wall: Possibilities and Scope in Indian Defense System
For the LASER wall installation in Indian defense system, we have to think about its geographical area and variations in climate across the country. As we know that Some places are too hot in the summer (above 490C) and some places are too cold in winter (below -500C)[1].So it is difficult for surveillance and patrolling. At those places, we can use an electronic wall which gives protection and surveillance from unauthorized entry. Laser wall technology consists of three major part e.g. LASER, Infrared Camera, and GPS system. An optoelectronic sensor is used to detect Laser beam through which a microcontroller regularly maintain a proper voltage level. If anyone cross that laser beam light then there is a disruption in voltage level and microcontroller generate a signal which is transmitted through GPS system and that warning signal being sent to the base camp station, thermal images of the particular area are also sent through GPS system simultaneously. Since each microcontroller may hold a unique ID of that particular location through which it can be easily identified by that location.

Working Of Air Compressor with Aid of Speed Braker
In our project, we are producing the compressed air using with the aid of speed breaker setup in roadways. This is the simple and easy method of producing the compressed air without using the electricity. Nowadays the electric power demand is increased. So we are generating the compressed air without using the electric power. Here instead of electric drive, we are using the mechanical drive to generate the compressed air.
