RPR:high-reliable low-cost geographical routing protocol in wireless sensor networks
Published 2012-05-01“…Geographical routing mechanisms were widely used in wireless sensor networks(WSN),by which data packets could be routed to the destination sensor node through a small amount of local routing information.Geographic routing algorithms usually required planar graphs derived the original network topologies.However,most planarization algorithms assumed a fixed communication radius of the sensor nodes,which mismatched real applications.The only practical algorithm brought in overheads in delet g and adding cross links.To provide a solution to the problem of existing algorithms,RPR (region partitioning-based routing) was introduced.RPR was a high-reliable and low-cost geographic routing protocol,which divided the whole network into of regular regions,and tried to perform a region-greedy routing on the virtual node of a region when th node-greedy routing failed.RPR had high reliability since the transmissions between regions could reduce the average length of the routing paths.Furthermore,RPR had low cost because its planarization phase did not check or delete cross links.Experiments show that RPR performs better than existing algorithms.…”

Non-invertible symmetry in Calabi-Yau conformal field theories
Published 2025-01-01“…Our approach begins at a Gepner point in the conformal manifold where the sigma model specializes to a rational conformal field theory and we can identify all supersymmetric topological Verlinde lines. By deforming away from this special locus using exactly marginal operators, we then identify submanifolds in moduli space where some non-invertible symmetry persists. …”

EFFECTS OF ADDING BRACKET JOINT ON RIGIDITY AND STRENGTH OF SPATIAL 3-ROD STRUCTURE OF BUS BODY
Published 2015-01-01“…Spatial 3-rod structure is one of the bus basic structures.Effects of the topological locations of angle brackets on the rigidity and strength of spatial 3-rod structure of bus body were discussed.The calculation by finite element calculation and experimental analysis showed that:1The structural rigidity and strength under bending loads were enhanced remarkably when the plane of angle bracket was parallel to the bending loads direction.2The structural rigidity and strength under torsion loads were enhanced remarkably when angle bracket was added at the top side of the joint between the load-carrying rod and side rod.3The most effective way to enhance the structural rigidity and strength and improve its high stress distribution was adding one angle bracket at the top side of the joint between the load-carrying rod and side rod and another angle bracket at the lateral side of the joint between the load-carrying rod and master rod( the tenth angle bracket location).This paper provided a valuable reference to the design of agricultural machinery and engineering structures,besides the bus body joints design.…”
