The overlay process is currently one of the main computational solutions used to integrate several data layers from different sources. Unfortunately, it is problematic when trying to overlay many layers. This leads to several geometric problems such as the management of sliver polygons. This paper proposes a new merging process to complement the vector overlay for data integration of several la...

A kind of embedded auto-leveling control system based on ARM and FPGA is proposed in this article. According to the mechanical structure and the control requirements of auto-leveling, the system combines the precision and high frequency of ARM with the internal logic configuration of FPGA. The control algorithm, hardware structure and software structure are discussed in the paper. This method n...

This is a brief review of vacuum string field theory, a new approach to open string field theory based on the stable vacuum of the tachyon. We discuss the sliver state explaining its role as a projector in the space of half-string functionals. We review the construction of D-brane solutions in vacuum string field theory, both in the algebraic approach and in the more general geometrical approac...
