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 ....etc

Patterns, Symmetry and Symmetry Breaking

Software Design pattern capture tried and successful design solutions. Among different views on design patterns is that they are created to compensate for the design shortfalls in programming languages that is, design patterns are needed when programming languages cannot do the job in straightforward way. There is a casual relationship between language features and design patterns and that relationship is couched in a more fundamental relationship between symmetries and broken symmetries. This paper ....etc

The problem of factoring a large number into the constituent primes is a time old one and many a scientists have dedicated their time and effort for developing a compact and efficient factoring algorithm. The RSA encryption algorithm developed by Rivest, Shamir and Adelman based on primality testing and prime factoring is one of the best encryption algorithms in use today.
Here we discuss some of the recent developments in the field of primality testing and also a comparison study with the primality testing algorithm of the IIT?ians is also gi ....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

Motivation for In Vivo Optical Imaging (Partial List)
• Safety — Non-ionizing radiation: photon energy is ~2 eV
• Physics — Molecular structure and composition of tissue
• Optics — High intrinsic contrast. E.g., absorption probes
 Oxy-hemoglobin & deoxy-hemoglobin
 Melanin
 Lipid
 Water
 DNA & RNA
• Physiology — Endogenous contrast for functional imaging
 Concentration of hemoglobin (angiogenesis)
 Oxygen saturation of hemoglobin (hyper-metabolism)
 Cell nuclei
 ....etc

Introduction

This study is motivated by a real problem at the Alang ship-dismantling facility near Bhavnagar in Gujarat. The focus of this study is the paint chip waste which is generated in ship breaking activity. Alang, located 56 Km away from Bhavnagar city in Gujarat, came up as ship breaking site during 1982-83. Hundreds of old ships, after their useful life, are broken at the Alang ship breaking yards without any precaution to protect the environment. Ship breaking and its harmful consequ ....etc
