Enhancement of A Road Sign Board Using Wireless Sensors

Road sign Detection and recognition is a real time system. It is also known as a Driver Assistant System(DAS) and it is one of the key technologies of Intelligent Transportation Systems (ITS). This System is being more and important with improving urban scale and increasing number of vehicles. Previous researches on this topic focus mainly on sign board detection with its color or shape. In this work, we present results of an attempt to locating traffic signs with wireless sensor networks which is useful to the driver to provide information regarding the traffic rules, instructions and information given on the road at the time of driving irrespective of the weather condition or any obstacle which may make sign boards difficult to see for drivers.

Topological Field Theories and Geometry of Batalin-Vilkovisky Algebras

The algebraic and geometric structures of deformations are analyzed concerning topological field theories of Schwarz type by means of the Batalin-Vilkovisky formalism. Deformations of the Chern-Simons-BF theory in three dimensions induces the Courant algebroid structure on the target space as a sigma model. Deformations of BF theories in $n$ dimensions are also analyzed. Two dimensional deformed BF theory induces the Poisson structure and three dimensional deformed BF theory induces the Courant algebroid structure on the target space as a sigma model. The deformations of BF theories in $n$ dimensions induce the structures of Batalin-Vilkovisky algebras on the target space.Comment: 25 page
