Abstract.
We introduce captcha, an automated test that humans can pass, but current computer programs canâ„¢t pass: any program that has high success over a captcha can be used to solve an unsolved Arti?- cial Intelligence (AI) problem. We provide several novel constructions of captchas. Since captchas have many applications in practical secu- rity, our approach introduces a new class of hard problems that can be exploited for security purposes. Much like research in cryptography has had a positive impact on algorithms for factoring and ....etc

Continuous Delivery Message Dissemination
Problems under the Multicasting Communication Mode


1.1 Abstract:
In the Continuous Delivery Message Dissemination (CDMD) problem, each message has a length and is partitioned into packets, however, the packets of every message must arrive at its destination in its original order, and all packets for each message must arrive during consecutive time units.
To cope with intractability, efficient Message dissemination appro ....etc

Power electronics remains an emerging technology. Two important factors in power electronics system are the switching speed of the devices and the total power loss in the system. If the switching speed can be increased ,improvements may be possible i.e. current ripples in an electrical machine or physical size of passive components may be reduced. Increased switching speed may cause additional losses in a power electronics system and increase the system cooling requirement. A common problem is that high-frequency phenomena like proximity eff ....etc

Solutions to Practical Unit Commitment Problems with Operational, Power Flow and Environmental Constraints
Presented By:
I. Jacob Raglend and Narayana Prasad Padhy1


Abstract”
In this paper, an algorithm to solve environmental constrained unit commitment problem (UCP) with operational and power flow constraints has been developed to plan an economic and secure generation schedule. Both Economic load dispatch (ELD) and Economic emission dispatch (EED) have been applied to obtai ....etc

HIGH PERFORMANCE CONCRETE (HPC) – A SOLUTION TO VARIOUS PROBLEMS

Shibu O.K

INTRODUCTION


High performance concrete (HPC) can be considered as a logical development of cement concrete in which the ingredients are proportioned and selected to contribute efficiency to various properties of cement concrete in fresh as well as hardened states.
High performance concrete (HPC) is defined as a concrete mixture which posses high workability, high strength, high modulus of elasticity, high dim ....etc

Abstract
This seminar describes the main issues facing the development of telerobotics systems connected to the Internet. The initial hurdle relates to the definition and implementation of an appropriate communication protocol for delivering real-time data. Two of the solutions proposed in the literature are briefly summarized. Then examines the issues relevant to control systems in the presence of time delay, with particular reference to telerobotic systems with force feedback. The delay introduced by Internet connections have specific charac ....etc
