M5-brane prongs, string soliton bound states and wall-crossing
We study abelian M5-brane field configurations representing BPS bound states
of self-dual string solitons whose locations correspond to the endlines of
M2-branes ending on the M5-branes. The BPS equations are obtained from
appropriate Bogomolny completion of the effective abelian low energy functional
with two transverse scalars, using two vectors representing the directions
along which these endline strings extend. Then we impose boundary conditions on
the scalars near the string soliton cores. This leads to a molecule-like
equilibrium structure of two non-parallel string solitons at fixed transverse
separations, with the M5-brane "prong" deformations comprising two "spikes",
each shaped like a ridge. The resulting picture becomes increasingly accurate
as one approaches the wall of marginal stability, on which these states decay.
There are various parallels with wall-crossing phenomena for string web
configurations obtained from D3-brane deformations.Comment: Latex, 44pgs, 3 figs, v2: further clarifications adde
Possible use of self-calibration to reduce systematic uncertainties in determining distance-redshift relation via gravitational radiation from merging binaries
By observing mergers of compact objects, future gravity wave experiments
would measure the luminosity distance to a large number of sources to a high
precision but not their redshifts. Given the directional sensitivity of an
experiment, a fraction of such sources (gold plated -- GP) can be identified
optically as single objects in the direction of the source. We show that if an
approximate distance-redshift relation is known then it is possible to
statistically resolve those sources that have multiple galaxies in the beam. We
study the feasibility of using gold plated sources to iteratively resolve the
unresolved sources, obtain the self-calibrated best possible distance-redshift
relation and provide an analytical expression for the accuracy achievable. We
derive lower limit on the total number of sources that is needed to achieve
this accuracy through self-calibration. We show that this limit depends
exponentially on the beam width and give estimates for various experimental
parameters representative of future gravitational wave experiments DECIGO and
BBO.Comment: 6 pages, 2 figures, accepted for publication in PR
ADVANCED EMBEDDED WIRELESS ROBOT WITH MOTION DETECTION SYSTEM AND LIVE VIDEO / AUDIO TRANSMISSION
This paper is to design and develop an intelligence robot to detect dangerous Gas/Smoke by using an 8 bit microcontroller. In our project the robot is designed to move automatically. The robot acts according to the command given by the program. It will move all the direction like forward, reverse, right and left. The Smoke sensing unit is available in robot mechanism. If particular Smoke is detected, robot will switch ON the Alarm Unit. The video and audio are monitored at the control unit. For transmitting audio and video, RF camera has been used
