This paper describes our retrieval system participated in the Patent Retrieval Task at the Fourth NTCIR Workshop. The main task was an associative patent retrieval task, in which a patent application including a target claim is used to search documents that can invalidate the demand in the claim. Our system can be characterized by the structure analysis for both target claim and entire applicat...

Construction Projects are being implemented under different contract systems in the Midwest. Negotiated design-build has been a popular contract system in recent years. It provides various advantages through entailing the contractor to be responsible for the whole project. However, design-build turns out to be risky system for both owners and contractors unless the risks are identified, quantif...

In this paper, we show the fundamentals of statistical method of structure analysis. Basic concept of a method is the average unit cell, which is a probability distribution of atomic positions with respect to some reference lattices. The distribution carries complete structural information required for structure determination via diffraction experiment regardless of the inner symmetry of diffra...

Two new types of hierarchy probability cost analysis (HPCA) model incorporating money allocated is money spent (MAIMS) principle based on definite work breakdown structure (WBS) level for EPC (engineering, procurement and construction) projects are presented. The proposed models have skillfully solved dilemma to appropriate cost elements and maximize the efficiency of information for cost risk ...

This paper considers two-dimensional interference-limited cellular radio systems. It introduces the shotgun cellular system that places base stations randomly and assigns channels randomly. Such systems are shown to provide lower bounds to cellular performance that are easy to compute, independent of shadow fading, and apply to a number of design scenarios. Traditional hexagonal systems provide...

The theme of this paper is the occurrence of risks within information technology and information systems investments. A taxonomy of the published classification frameworks of IT related risk is presented and a new comprehensive classification framework for IT investments (the TOPModel) is presented within the TRIP model of the risk factors and critical factors affecting IT investments. Risk man...

Governance, Risk, and Compliance (GRC) is an emerging topic in the world of business and information technology. However to date there is a lack of research on an integrated approach to GRC has hardly been researched. In this paper we construct an integrated process model for high-level IT GRC management. First, we discuss existing process models for integrated GRC. Then we set the scope of our...

4 SUMMER/FALL 1999 T’S A RACE with no starting point, no fixed course, and really no rules at all: walk, run, ride, do anything you want. Form a team, as big as you like. Build any sort of machine you wish with whatever money you can get your hands on. Just get to the finish line first. That finish line isn’t a particular place but a new understanding of a symmetry (or rather, an almost symmetr...
