V2V (Vehicle to Vehicle) Communication

V2V (Vehicle to Vehicle) Communication

The objective of ambient intelligence is to create an intelligent daily space, which is immediately usable and integrated into our homes, our offices, our roads, our cars, and everywhere. This new concept must be invisible; it must blend in with our normal environment and must be present when we need it.   One of the application of this concept consists of providing our cars and roads with capabilities to make road more secure (information about the traffic, accidents, dangers, possibl

Automated Manual Transmission

MT (manual transmission) uses simple spur gears providing excellent transmission efficiency and thus typically get 10% or better fuel mileage than current ATs (automated transmissions). The object of the ATM (automated manual transmission ) is to automate starting and gear shifting while retaining this excellent fuel efficiency. A round of fierce competition was triggered among European manufacturers to see who would be the first to develop what is generally known as a conventional AMT that atte

DRIVERLESS CARS

For generations, the automobile industry has been a source of innovation and economic growth. The ability to drive is a symbol of mobility and independence that spans generations. Clearly, automobiles play a significant role in our lives and afford many benefits to society.   Yet for all benefits conferred on society, no other invention in the history of civilian technology has caused as much harm as the automobile. Every 30 seconds. someone dies in a traffic accident, adding up to wel

CNG in India

Compressed natural gas(CNG) is a fuel that needs no introduction.  it is a cheap fuel to make and use, which is why it is so widespread in public transport. Not to mention that the second hand car market is greatly supported by CNG kits. vehicles like the Honda Civic, Accord and Toyota Corolla are favorites to be bought second hand and then have green fuel kits used to make them easy on the pocket. With diesel deregulation soon to kick in, the price of the oil will head north soon, so CNG seems

Desicant Cooling System

In the last 10 years, evaporative and desiccant cooling technology for air conditioning has increased as an alternative for air conditioning systems has increased as an alternative to the conventional vapour compression systems. A typical system combines a dehumidification system that uses a rotary desiccant wheel, with direct or indirect evaporative systems, allowing a filtered and cooled air supplying temperature, humidity and speed conditions that propitiate environmental thermal comfort, eve

Experimental Analysis of an Air Washer

Hello World,   Today i will like tell you all about my 4th year project which was on the topic of experimental analysis of an air washer. In the recent sanario the peoples are slowly getting conscious about the beast(pollution) intended to destroy our beautiful sphere(earth). This pollution had drastically spread in our world drastically in few years. It is sad to say but we are only responsible for it. The careless burning of fossil fuels, heavy growth in industries and invention

A Problem in Statics & Dynamics, #34

Mechanics Corner     A Journal of Applied Mechanics and Mathematics by DrD, # 34     © Machinery Dynamics Research, 2015 A Problem in Statics & Dynamics           Introduction         A problem was recently posted on this Forum, requesting help, that has led me to consider a somewhat more general problem for this post. The scope of this post will include the original problem, although not by the method required there, but will also go beyond to a more general geometry.

What are hydraulic cylinders,working principles !!

Hydraulic cylinders haven’t really changed a lot over the years. The manufacturing processes are much more streamlined and the tolerances are much tighter, but for the most part cylinders are still the hard working push/pull tools they have always been. These things have literally shaped the world around us. Anything that gets lifted, pushed, hauled, dumped, dug, crushed, drilled or graded has gotten that way by some truck, crane, dozer or tractor using a hydraulic cylinder. But how do hydraulic

If There Is a Fastener There Will Be a Tool That Requires Access.

I get great satisfaction when working with my hands. When I do so I always ask why the item I am working on is as it is. One source of frustration I believe many have experienced it the lack of tool access. Sometimes n-1 fasteners are a breeze to access and the nth takes more time to remove than all the other combined. I don’t recall from my machine design class ever addressing this real world situation. I learned how to size bolts, bearings, and cross-sections but I don’t recall any mentio

Over Engineered or Over Designed?

I recall many years ago first hearing the term Over Engineered. It rang a sour note but I had not given it much thought. I still hear this said today about older equipment. For instance the DC Generators at Pratt Institute in Brooklyn NY have been in operation for over 100 years. http://inspectapedia.com/heat/Steam_Systems_Pratt_Milster.php I had the opportunity a few years ago to visit my alma mater. To my surprise and delight the Chief Engineer who provided the tour of the facility to my class

5 tips to survive a Seminar successfully!

Seminars have always been an important aspect of education. It's an opportunity to either gain knowledge on an unknown topic or develop ideas regarding something you already know.It's a place where you meet highly skilled persons and get to know their recent researches.You should attend at least a couple of seminars annually to keep yourself updated about the advancements taking place in your field. I've seen many people who keep avoiding seminars, although interested, just because they have nev

BUE formation during machining

What is a BUE? BUEs are built-up edges formed due to the accumulation of work-piece material against the rake face of the tool. How are BUE formed? During machining, the upper layer of the work-piece metal experiences a large shear force as it comes in contact with the tool-tip and an amount of the metal gets welded to the tool-tip. This is due to work hardening of the metal layer. The metal adhered to the tool becomes so hard that it is difficult to remove.     Why a

Types of Kinematic pairs

When two links (or elements) in a machine are in contact with each other, they form a pair. When the relative motion between these two links is completely or partially constrained, then the links are said to form a kinematic pair.In simple words, a kinematic pair or simply a pair is a joint of two links having relative motion between them.    Kinematic pairs can be classified on the basis of:   1) Nature of contact between the pairing elements  (a) Lower pair – surface

Advanced Polynomial Curve Fitting

Mechanics Corner     A Journal of Applied Mechanics & Mathematics by DrD, #33     © Machinery Dynamics Research, 2016 Advanced Polynomial Curve Fitting     The use of polynomials to fit engineering data is a common engineering practice. In school, we learn that "A data set consisting of n data points ((x_{i},y_{i}), i=1,2,3,…n) can be exactly fitted with a polynomial of degree n-1. Thus three data points can be fitted exactly with a quadratic expression, four data points ca
