Recent Trends in Indian IPO Market

IPOs witnessed a sharp decline in collections during the June 2008 quarter, indicating a fall of 88.45% from the year-ago levels. The data on number of IPOs that were issued are not encouraging either. The sentiment of the investors can be traced back to the overvalued Reliance Power IPO during Q4'07. This was an issue from the Ambani stable, which was the most high profile sufferer. Reliance Power ended its first day on the markets at Rs. 372 against issue price ....etc

ABSTRACT


Many organizations are working hard to secure themselves from the
growing threats of message hacking through various trends in
cryptography.Yet the headlines are dominated with the latest news of
message passing disaster more frequently than any time before.This
document intends to review this problem and propose several possible
solutions.The cryptographic industry has been responding to these
threats with ever-quicker responses to the rapid onslaught of malicious
techniques,while corp ....etc

Discovery of Periodic Patterns in Spatiotemporal Sequences- IEEE TRANSACTIONS ON KNOWLEDGE AND DATA ENGINEERING, VOL. 19, NO.

java


Abstract—
In many applications that track and analyze spatiotemporal data, movements obey periodic patterns; the objects follow the same routes (approximately) over regular time intervals. For example, people wake up at the same time and follow more or less the same route to their work everyday. The discovery of hidden periodic patterns in spatiotemporal data could unveil important information to ....etc

Trends in appliance motors

Permanent magnet synchronous motors beginning to replace split-phase induction motors in appliances , a means of boosting efficiency while reducing part costs. PM synchronous motors work at variable speeds and may become part of the appliance structure itself , perhaps eliminating the need for separate gearboxes and belt drives used to harness power from induction motors.

Compiler writing techniques have undergone a number of major revisions over the past forty years. The introduction of object-oriented design and implementation techniques promises to improve the quality of compilers, while making large-scale compiler development more manageable.

In this seminar you want to show that a new way of thinking of a compiler's structure is required to achieve complete object-orientation. This new view on compiling can lead to alternative formulations of parsing and code generation. In practice, the object-oriented ....etc

One of the main goals of the study of robotics today is to understand not only the control systems used to stabilize the position, motion, and other forces of the robot, but also to allow robots to effectively work via sensors and actuators in dynamic environments.

The field of robotics has its origin in science fiction, the term ROBOT was derived from the English translation of a fantasy play written in Czecholosolvakia around 1920. It took another 40 years before the modern technology of industrial ROBOTS began. Today robots are highly au ....etc
