Breaking Audio CAPTCHAs



Introduction

CAPTCHAs are automated tests designed to tell computers and humans apart by
presenting users with a problem that humans can solve but current computer programs
cannot. Because CAPTCHAs can distinguish between humans and computers with high
probability, they are used for many different security applications: they prevent bots from
voting continuously in online polls, automatically registering for millions of spam email
accounts, autom ....etc

Accidents
There are many systems like air bags, GPS, robo driven cars, tracked cars etc which can avert accidents to some extent.
But they are not much effective and hence loss of lives is continuing.
REASONS FOR ACCIDENT
Ignoring traffic rules
Drunken driving
Dream driving
Mechanical failures in the vehicle
Mistakes of the drivers
vision
Braking distance of a vehicle for a particular speed is the distance at which the vehicle comes to a halt from the current speed from the point of applicatio ....etc

Abstract Throughput capacity in mobile ad hoc networks has been studied extensively under many different mobility models. However, most previous research assumes global mobility, and the results show that a constant per-node throughput can be achieved at the cost of very high delay. Thus, we are having a very big gap here, i.e., either low throughput and low delay in static networks or high throughput and high delay in mobile networks. In this paper, employing a practical restricted random mobility model, we try to fill this gap. Specifically, ....etc

An anti-lock braking system or anti-skid braking system (ABS) is an automobile safety system that allows the wheels on a motor vehicle to maintain tractive contact with the road surface according to driver inputs while braking, preventing the wheels from locking up (ceasing rotation) and avoiding uncontrolled skidding. It is an automated system that uses the principles of threshold braking and cadence braking which were practiced by skillful drivers with previous generation braking systems. It does this at a much faster rate and with better con ....etc

HIGHWAY SPEED SENSING AND AUTOMATIC BREAKING SYSTEM
INTRODUCTION
It will consist of a transmitter and a receiver system . Receiver will be kept in the vehicles and transmitters would be installed on the road. It will not use any speed sensing device, instead four switches. Which could be operated by traffic Cops, limit 80, limit40,limit20 and no horn area, are provided . when ever these switches are pressed, they will transmit the corresponding alert message to the driver .
Recei ....etc
