By former results, we know that the pyramid network is Hamiltonian and Hamiltonian-connected. In this paper, we show that the pyramid network with one node fault is Hamiltonian-connected excluding a special faulty case by constructing a Hamiltonian path between any two distinct nodes in it. That is the pyramid network with one node failure is almost Hamiltonian connected.
We have proposed unifying presentation contents, such as lecture video and presentation slides used in lectures, using metadata. For the unified contents, we have also proposed a search mechanism named UPRISE (Unified...

The DEVS formalism was defined as a method for modeling and discrete event systems. DEVS theory evolved and it was lecently upgraded in order to permit modeling of continuous and hybrid systems. We have built a compiler of a subset of Modelica, and built a translator into DEVS models. We show how to model these dynamic systems under the discrete event abstraction. Examples of model simulations with their execution results are included. An experimental analysis on quantization methods within the Modelica models created is also presented in this paper.

In this paper, we propose a novel millimeter-wave (mm-wave) band radio over fiber (RoF) system with dense wavelength division multiplexing (DWDM) star architecture. Two lasers with a small wavelength difference, phase locked and polarization-aligned, are allocated at a central station (CS) for connecting the CS and each base station (BS);one laser is used for transmitting light and the other for the remote local oscillator. For the conceptual illustration, we consider a DWDM RoF system with a channel spacing of 12.5 GHz and radio frequency (RF) of ∼30-GHz mm-wave band. In the downlink system, a single-side band (SSB) subcarrier is used with low RF imposed onto an optical carrier at the CS, and an mm-wave band RF signal is obtained at each BS using direct photo-detection by the SSB subcarrier beat with the remote oscillator. In the uplink system, the received mm-wave band RF signal at each BS is imposed onto the two optical carriers simultaneously, one optical carrier with the closest SSB subcarrier is optically filtered out and fed into in the uplink transmission fiber without frequency interleaving;the electrical signal with a low intermediate frequency can be photo-detected directly at the CS. Such a RoF system has simple, cost-effective and maintenance reduced BS's, and is immune to laser phase noise in principle.

We calculate the evolution of the loss, dispersion, and mode shape in a tapered microstructure optical fiber. We show that the primary limitation on mode compression is the loss due to mode leakage. © 2005 Optica...
