DIFFERENTIAL DRIVE ROBOTIC ROVER
no vote
A robot obstacle detection system
comprising: A Robot housing which navigates with respect to a surface; a sensor
subsystem having a defined relationship with respect to the housing and aimed
at the surface for detecting the surface. The sensor subsystem including: An
optical emitter which emits a directed beam having a defined field of emission,
and a photon detector having a defined field of view which intersects the field
of emission of the emitter at a finite region; and a circuit in communication
with the detector for redirecting the robot when the surface does not occupy
the region to avoid obstacles.

DIGITAL PARKING SYSTEM
no vote
This
project aims to design a three tier parking system.
The
project will keep track of the duration
for which cars are parked. The lowest tier will have those cars parked for
short interval (few mins).The middle tier will contain cars which will remain
for 1-3 hrs. Cars which will remain in the lot for more than 3hrs will be in
upper tier.
It
is based on the technology which takes a pictu

Digital Invisible Ink Data Hiding Based on Spread-
no vote
A novel
data-hiding methodology, denoted as digital invisible ink (DII), is proposed to
implement secure steganography systems. Like the real-world invisible ink,
secret messages will be correctly revealed only after the marked works undergo
certain prenegotiated manipulations, such as lossy compression and processing. Different
from conventional data-hiding schemes where content processing or compression
operations are undesirable, distortions caused by prenegotiated manipulations
in DII-based schemes are indispensable steps for revealing genuine secrets. The
proposed scheme is carried out based on two important data-hiding schemes:
spread-spectrum watermarking and frequency- domain quantization watermarking.
In some application scenarios, the DII-based steganography system can provide
plausible deniability and enhance the secrecy by taking cover with other

Simulation of Doubly-Fed Induction Generator in a
4.0
In order to meet power needs, taking into account economical and environmental factors, wind energy conversion is gradually gaining interests as a
suitable source of renewable energy. In a country like mine where there is not a single kW installed wind energy, the question is, How to simulate and explore
the transients of these variable speed devices? This paper deals with simulation of a Wind Turbine based on a doubly-fed induction machine used in
generating mode to produce electrical energy on a guru111246 2016-08-23
