The Information Age has revolutionized the way students learn in the classroom. The United States Military Academy (USMA) emphasizes the importance of Information Technology (IT) through an academy-wide IT specific goal. This goal supports the USMA's mission of producing Army Officers who can respond effectively to technological changes in the defense of our nation. Courses augmented with IT can be daunting for cadets who lack the experience and confidence level to succeed in the course. As a result, these types of courses are avoided by cadets if at all possible. This is not an option for an aspiring officer who will lead the soldiers of tomorrow on a digitized battlefield. Since 1990, cadets have been issued a computer which has played a central role in bringing the power of IT to all graduates of the Military Academy. Integration of IT in the curriculum begins early with every cadet receiving a laptop computer. An integrated software package is included to support any course of instruction. Cadets receive two courses in IT, one in their freshman year and one in their junior year. The freshman course teaches the cadet the basic functionality of the laptop, a basic programming language, and creating a basic website. The junior course builds on the freshman course by teaching the cadets to create an advanced website, design and build a network, manage a database, and create an information system. IT plays a central role in several overlap courses between engineering and the humanities in such areas as information warfare, terrorism, and the legal aspects of intellectual property rights. What makes this approach unique is the methodical diffusion of IT into course design which removes the barrier between learning and the implementation of IT as an academic multiplier. An academy-wide committee consisting of 12 members is responsible for examining collected data to see how well the Military Academy is meeting its LT goal. This data comes from a variety of sources such

This paper puts forward a paradigm to resolve the real-time conflict detection using prior knowledge and context in CSCW plant design system from the plant design practice. Generally speaking, the performance of CSCW plant design is decided by the conflict management. And the conflict detection in CSCW plant design is a very complicated and time-consuming process, especially the engineering conflict. Firstly, the paper discusses the concept of prior knowledge and real-time engineering conflict detection and classifies the prior knowledge in CSCW plant design into inheritable knowledge and contextual knowledge. And then, the paper presents an algorithm that resolves the real-time engineering detection. This is done by decomposing the engineering conflict detection into internal engineering conflict and external engineering detection based on the divide-and-conquer paradigm and processing them separately using prior knowledge and context combining spatial partitioning and BVHs. The gist of this paper is (1) to introduce a concept that adopting prior knowledge can make some complex computing simple and (2) to resolve real-time conflict detection in CSCW plant design. ©2007 IEEE.

Infinite games with incomplete information are common in practice. First-price, sealed-bid auctions are a prototypical example. To solve this kind of infinite game, a heuristic approach is to discretise the strategy spaces and enumerate to approximate the equilibrium strategies. However, an approximate algorithm might not be guaranteed to converge. This paper discusses the utilisation of a best response algorithm in solving infinite games with incomplete information. We show the constraints of the valuation distributions define the necessary conditions of the convergence of the best response algorithm for several classes of infinite games, including auctions. A salient feature of the necessary convergence conditions lies in that they can be employed to compute the exact Nash equilibria without discretising the strategy space if the best response algorithm converges.

OWL-S Service Profile provides a way to describe services offered by providers and services needed by requesters. But some items in the Profile are not very suitable for describing a requester's demands while some important information about the requester himself such as his identity which may play important role in precondition match are not considered in the Service Profile. In this paper we define an OWL compatible Request Profile ontology especially for service requesters to describe their special properties and their expectation about a service. Then a match algorithm is proposed to match service request described in Request Profile with service advertise described in Service Profile. The experiment results show that the match algorithm is efficient.

Most of existing approaches on event detection in sports video are general audience oriented. The extracted events are then presented to the audience without further analysis. However, professionals, such as soccer coaches, are more interested in the tactics used in the events. In this paper, we present a novel approach to extract tactic information from the goal event in broadcast soccer video and present the goal event in a tactic mode to the coaches and sports professionals. We first extract goal events with far-view shots based on analysis and alignment of web-casting text and broadcast video. For a detected goal event, we employ a multi-object detection and tracking algorithm to obtain the players and ball trajectories in the shot. Compared with existing work, we proposed an effective tactic representation called aggregate trajectory which is constructed based on multiple trajectories using a novel analysis of temporal-spatial interaction among the players and the ball. The interactive relationship with play region information and hypothesis testing for trajectory temporal-spatial distribution are exploited to analyze the tactic patterns in a hierarchical coarse-to-fine framework. The experimental results on the data of FIFA World Cup 2006 are promising and demonstrate our approach is effective. Copyright 2007 ACM.

Due to the existence of a large amount of legacy information systems, how to obtain the information and integrate the legacy systems is becoming more and more concerned. This paper introduces the integration pattern based on agent grid. And we propose an agent grid intelligent platform called AGrIP, which can erase information islands and integrate external systems efficiently by encapsulating the distributed application system to agents. AGrIP adopts distributed hierarchical structure, which is capable of integrating external systems to provide the users various services dynamically. AGrIP has proved itself scalable and efficient during the industry projects development and application. © 2007 IEEE.
