Deep submicron CMOS integrated circuit reliability simulation with SPICE
The purpose of the paper is to introduce a new failure rate-based methodology for reliability simulation of deep submicron CMOS integrated circuits. Firstly, two of the state-of-the-art MOSFET degradation models are reviewed. They have been developed into reliability simulation tools and commercialized in industry for many years, however, their inherent limitations of characterizing circuit lifetime, including tedious processes for extracting device degradation parameters and model fitting parameters, impeded their wide applications in the product's front-end design process. Secondly, a set of accelerated lifetime models for the most important intrinsic silicon degradation mechanisms are proposed. These lifetime models correlate a device's electrical operating parameters to its mean time to failure (MTTF) in simple forms. Finally, a new failure rate-based SPICE reliability simulation methodology is developed, in which MTTF and failure in time (FIT) are the primary reliability parameters to be characterized. The power of this new reliability simulation method, due to its simplicity, makes it an important design-for-reliability tool for electronic product developers.

Automatic image-to-site model registration
Image-to-site model registration is critical to model supported exploitation of aerial and satellite imagery. This paper presents a fully-automatic registration method. This method uses a multi-resolution image-to-image registration process assuming both affine and projective transformations to determine and refine the locations of 3D control points in the new image. Camera resection is subsequently accomplished. Registration results obtained on real imagery show good performance.

An Internet based virtual exhibition system: conceptual design and infrastructure
Abstract Virtual reality technology has wide applications in manufacturing, service industry, and medical training. In addition to essential presence, virtual reality provides secure and economical environment for participants to experience the virtual world rather than the corresponding real world. With advent of rapidly developed technology, there are numerous new products and projects to be introduced in exhibition shows over the world everyday and it is neither prudent nor possible to attend all of them. There have been overwhelming amount of virtual exhibitions available on the Internet; however, most of them are not satisfactory in terms of performance and users cannot get a full understanding on the product interested due to low sense of presence. Information coordination, other than information share and distribution, between the participants is crucial but not yet well defined in the current virtual exhibitions. It is prominent to develop Internet based virtual reality exhibition systems that agglomerate the advantages of efficiency/accessibility on the Internet and high sense of presence in virtual environment. The Internet based virtual exhibition systems are not only as informative as traditional exhibitions but also more flexible to relax temporal and spatial constraints to allow users attend exhibitions anytime and anywhere.

cisRED: a database system for genome-scale computational discovery of regulatory elements
We describe cisRED, a database for conserved regulatory elements that are identified and ranked by a genome-scale computational system (). The database and high-throughput predictive pipeline are designed to address diverse target genomes in the context of rapidly evolving data resources and tools. Motifs are predicted in promoter regions using multiple discovery methods applied to sequence sets that include corresponding sequence regions from vertebrates. We estimate motif significance by applying discovery and post-processing methods to randomized sequence sets that are adaptively derived from target sequence sets, retain motifs with p-values below a threshold and identify groups of similar motifs and co-occurring motif patterns. The database offers information on atomic motifs, motif groups and patterns. It is web-accessible, and can be queried directly, downloaded or installed locally.

The MicroGrid: a Scientific Tool for Modeling Computational Grids
The complexity and dynamic nature of the Internet (and the emerging Computational Grid) demand that middleware and applications adapt to the changes in configuration and availability of resources. However, to the best of our knowledge there are no simulation tools which support systematic exploration of dynamic Grid software (or Grid resource) behavior. We describe our vision and initial efforts to build tools to meet these needs. Our MicroGrid simulation tools enable Globus applications to be run in arbitrary virtual grid resource environments, enabling broad experimentation. We describe the design of these tools, and their validation on micro- benchmarks, the NA parallel benchmarks, and an entire Grid application. These validation experiments show that the MicroGrid can match actual experiments within a few percent (2% to 4%).
