Internet access now is not only limited to computer devices but can now be easily accessed through mobile devices viz. Smartphones, tablets, PDA’s. The internet is now available to every common man, and with its use he fires many queries on servers and uploads or ...

This paper presents EME, a low-cost solution for a highly modular multiprocessing hardware-software environment useful in designing autonomous mobile robots. High processing capabilities, the ability to interface a large number of sensors and actuators, extensibility, redundancy and exibility are issues addressed by this environment. An autonomous robot equipped with two cameras, one for line-f...

This review-essay explores the uses and limits of cost-benefit analysis in the context of environmental protection, focusing on three recent books: Priceless, by Frank Ackerman and Lisa Heinzerling; Cellular Phones, Public Fears, and A Culture of Precaution, by Adam Burgess; and Catastrophe: Risk and Response, by Richard A. Posner. The review-essay emphasizes three principal limitations on the ...

An Autonomous Environmental Sensor (AES) is a miniature electronic package combining position location capability (using the Global Positioning System (GPS)), communications (packet or voice-synthesized radio), and environmental detection capability (thermal, gas, radiation, optical emissions) into a small, inexpensive, deployable package. AESs can now be made with commercial off-the-shelf comp...

In empirical tests guided by recent theory (e.g., Hughes, Liu and Liu 2007; and Lambert, Leuz and Verrecchia 2012), we examine the joint effects of information asymmetry and information precision on the cost of capital and how these effects vary based on the amount and quality of available information and the level of market competition. Consistent with theory, we find that average information ...
