CityGML, an OGC standard, is an open data model for virtual 3D city models and includes buildings, roads, terrain, water bodies, etc. While many modules are well-developed (eg buildings, bridges, tunn...
Besides the conventional bosons and fermions, in synthetic two-dimensional (2D) materials there could exist more exotic quasiparticles with non-Abelian statistics, meaning that the quantum states in t...
A novel polarizer is designed by liquidfi lling in partial air-holes of a hollow-core photonic bandgap fi ber(PBGF) forming an asymmetric waveguide structur e, which leads to the vertical polarization...
We propose an eight-channel all-optical switch using a multimode interference phenomenon. This structure is based on the cooperation of self imaging and self guiding in nonlinear multimode interfere...
Reliable technique to determine the cutoff wavelength using single-mode fiber as a reference is newly proposed. This technique identifies cutoff wavelength of 1st higher-order-mode in BIF precisely, w...
The various communication technologies draw much attention for intelligent transport system (ITS). Especially, the ad hoc network between cars is one of main research topics for ITS and those networks...
