Automation of Lubrication System

In engines, frictional losses are mainly due to slide as Well as rotating parts Engine friction is expressed in terms of frictional power Friction all losses is mainly attributed to the following mechanical losses

• Direct frictional losses
• Pumping losses
• Power loss to drive the components to change and scavenge Power loss to drive other auxiliary components

A good engine design should not the total frictional losses to be more than 30%of energy input in Reciprocating engine. It should be the aim of a good designer to reduce friction and wear of the parts subjected to relative motion. This is achieved by proper lubrication system

1. Direct Frictional Losses:

It is the power absorbed due to the relative motion of different bearing surfaces such as

• Piston rings,
• main bearings,
• Cam shaft bearings etc…

2. The frictional losses are comparatively higher in the reciprocating engine.

3. Pumping Loss For4-stroke engines Considerable amount of energy is spent during the exhaust

Processes. The pumping loss is the net power spent by the engine (piston) on the working medium (gasses) during intake and exhaust strokes. For2-stroke engines this is negligible since the incoming fresh mixture is used to scavenge the exhaust gasses Power Loss to drive the components to change and scavenge 4-strokeengine. In turbo/supercharged engines the intake charge is supplied at A higher pressure than the aspirated engines For this purpose mechanically driven compressor or turbine driven compressor used accordingly the engine is called Supercharged or turbocharged engine.

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.
