Photonic band-gap (PBG) materials are periodic dielectric crystals that exhibit a photonic band-gap analogous to the electronic band-gap present in semiconductors. Their fabrication, however, requires extremely high resolution and is very costly. Due to the high expense in experimental fabrication, accurate modeling and prediction of a novel PBG structure characteristics are highly desirable. This paper presents an investigation on the effects of dielectric material properties and structures on the photonic band characteristics by using numerical simulation approaches. © 2003 IEEE.

SWENET: The Network Community for Software engineering Education is an NSF funded project to develop curriculum modules of value to faculty member's desiring to incorporate software engineering concepts in new or existing courses. By design, the modules are self-contained instructional units ranging from a single lecture to approximately one week of course material;in this way, instructors can adopt, adapt, and arrange modules as appropriate to their courses. The original goal was to provide appropriate coverage at the undergraduate level for the areas defined in the Software engineering Body of Knowledge. Recently the focus has shifted to the more focused Software engineering Education Body of Knowledge developed as part of the computing Curricula - Software engineering effort. As such, SWENET is evolving to become a repository of course modules that can support a wide range of educational approaches within the general framework defined by these bodies of knowledge. © 2003 IEEE.

System on devices (SyD) is a specification for a middleware to enable heterogeneous collections of information, databases, or devices (such as hand-held devices) to collaborate with each other. This paper illustrates the advantages of SyD by describing a prototype calendar of meetings application. This application highlights some of the technical merits of SyD by exploiting the use of coordination links. Based on the underlying event-and-trigger mechanism, these links allow automatic updates as well as real-time enforcements of global constraints and interdependencies, not available with existing calendar applications. Additionally, the calendar application illustrates coordination among heterogeneous devices and databases, formation and maintenance of dynamic groups, mobility support through proxies, and performance group transactions across independent data stores. © 2003 IEEE.

System of Mobile Devices (SyD) is a middleware we developed that can he used for implementing collaborative, mobile, and distributed applications over heterogeneous devices, data stores, and computing environments. Current prototype implementation of SyD consists of five modules. These modules provide ease of programming in the areas of distributed communication, remote method invocation, service publication and discovery, directory services, distributed service invocation and aggregation, event handling, collaborative link creation and enforcement. A central module is SyDLink which allows SyD-based applications to create "coordination" links. Coordination links represent dependencies among heterogeneous devices and application components. Based on the underlying event-and-trigger mechanism, they allow automatic updates as well as real-lime enforcement of global constraints and interdependencies. SyDLink objects provide the underlying mechanism in SyD to enforce atomic execution of distributed transactions. We explain and demonstrate the use of SyDLink objects via a running example, a collaborative SyD calendar application, throughout the paper. © 2002 IEEE.

This session is an interactive panel designed to give potential authors some insight into the process of writing a textbook. The session will describe the basic process for publishing a textbook, from developing the initial idea, to obtaining a contract, to completing the book. Panelists will also share their personal insights on the entire process. This session is designed to be highly interactive and should draw the audience strongly into the discussion. © 2003 IEEE.

A new hybrid finite-difference time-domain-mixed potential integral equation method (FDTD-MPIE) is proposed for modeling and simulating multilayer planar problems with possible locally inhomogeneous geometries. By using equivalent principle, the original problem can be divided into different regions. The fields in the inhomogeneous regions are modeled by using FDTD method, which is a time domain method providing broad band fields information. The resultant interaction matrix from FDTD can be used as a look-up table for subsequent model coupling procedure. The fields in the layered structure with possible perfect electric conductors are described in terms of the equivalent electric and magnetic surface current densities by a mixed potential electric-field integral representation with less singular kernals. The interactions between the FDTD model and MPIE model are coupled together by enforcing the continuity of the tangential electric and magnetic fields at the equivalent surface using a Galerkin testing procedure. Numerical results of a canonical test problem are presented to validate the hybrid FDTD-MPIE method. © 2003 IEEE.

For earthquake simulations to play an important role in the reduction of seismic risk, they must be capable of high resolution and high fidelity. We have developed algorithms and tools for earthquake simulation based on multiresolution hexahedral meshes. We have used this capability to carry out 1 Hz simulations of the 1994 Northridge earthquake in the LA Basin using 100 million grid points. Our wave propagation solver sustains 1.21 teraflop/s for 4 hours on 3000 AlphaServer processors at 80% parallel efficiency. Because of uncertainties in characterizing earthquake source and basin material properties, a critical remaining challenge is to invert for source and material parameter fields for complex 3D basins from records of past earthquakes. Towards this end, we present results for material and source inversion of high-resolution models of basins undergoing antiplane motion using parallel scalable inversion algorithms that overcome many of the difficulties particular to inverse heterogeneous wave propagation problems. © 2003 ACM.

MPI-based parallelized precorrected FFT algorithm for analyzing scattering by arbitrarily shaped three-dimensional objects

Progress in Electromagnetics Research 2003年 42卷 247-259页

In this paper, how to parallelize the Pre-corrected FFT algorithm for solving the scattering problem of large scale is presented and discussed. The P-FFT technique developed by our group earlier was extended in the current analysis. To show the efficiency of the MPI-based parallelization algorithm, the experiment results are given in the latter part of the paper and various comparisons are made for such a demonstration.
