An architecture design of the intelligent agent for speech recognition and translation is presented in this paper. The design involves the agent architecture and the method of the agent is used. The architecture design shows the relationship between the intelligent agent and speech recognition also translation. The intelligent agent for speech recognition is called S-AGENT and T-AGENT for translation. The purpose of the S-AGENT is to facilitate for transmitting the speech data via Internet or network. The S-AGENT is acting as a data transmit control to ensure the transmitted speech data is securely delivered. The task of the T-AGENT is different from the S-AGENT. The T-AGENT is acting as information retrieval. It processes the output from the speech recognition and translates the output based on its information memory database. If the information cannot be found on its memory, it searches the information required from the database dictionary provided. At the same time, it learns the information and saves the information to its memory for the future purpose.

Guangzhou Symposium on Satisfiability and its Applications

＜正＞ Recently the Mathematical Programming community showed a renewed interest in Hilbert’s Positivstellensatz. The reason for this is that global optimization of polynomials in R[x1,..., xn] is NP-hard, while the question whether a polynomial can be written as a sum of squares has tractable aspects. This is due to the fact that Semidefinite Programming can be used to decide in polynomial time （up to a prescribed precision） whether a polynomial can be rewritten as a sum of squares of linear combinations of monomials coming from a specified set. We investigate this approach in the context of Satisfiability. We are interested in the question whether the Satisfiability area can provide examples of polynomials which are non-negative but not sums of squares but also examine the potential of the theory for providing tests for unsatisfiability and providing MAXSAT upper bounds. We compare the SOS （Sums Of Squares） approach with existing upper bound techniques （for the MAX-2-SAT case） of Goemans and Williamson [6] and Feige and Goemans [5], which are based on Semidefinite Programming as well. We advocate that the SOS approach gives more accurate upper bounds at comparable computational costs.

The current debate about the teaching of data structures is hampered because, as a community, we usually debate specifics about data structure implementations and libraries, when the real level of disagreement remains implicit - the intent behind our teaching. This paper presents a phenomenographic study of the intent of CS educators for teaching data structures in CS2. Based on interviews with computer Science educators and analysis of CS literature, we identified five categories of intent: developing transferable thinking, improving students' programming skills, knowing "what's under the hood", knowledge of software libraries, and component thinking. The CS community needs to first debate at the level of these categories before moving to more specific issues. This study also serves as an example of how phenomenographic analysis can be used to inform debate on syllabus design in general. Copyright 2004 ACM.

Wireless sensor network technology promises to reveal fine-grained, dynamic changes in monitored variables of an outdoor landscape. But there are significant problems to be overcome in translating this vision to working systems. This paper describes the design and implementation of a reactive, event driven network for environmental monitoring of soil moisture and evaluates the effectiveness of this solution. A novel feature of our solution is its reactivity to the environment: when rain falls and soil moisture is changing rapidly, measurements are collected frequently, whereas during dry periods, between rainfall events, measurements are collected much less often. Reactivity allows us to focus on dynamic responses and limit the amount of useless data gathered, as well as improving robustness and network lifetime. The main contribution of the paper is to demonstrate that a reactive sensor network can deliver useful data on soil moisture responses to rainfall. Field trial results on the reactivity, robustness and longevity of the network are evaluated, and future improvements proposed.

Trees are one of the most important elements of natural landscapes. Therefore, in computer graphics, there is a great demand for methods to realize the natural representation of trees in virtual landscapes in various fields such as entertainment industry or environmental assessment in construction. Many studies have been made on techniques in which the shapes of trees are modeled but only a few studies have been reported on methods to incorporate the shapes with motions in a wind field. Most of these studies use physical simulation techniques based on the equations of motion to generate the branch motions and cannot realize the motions of individual leaves. In this paper, we propose a method to create the natural motions of individual leaves and branches swaying in a wind field. This method generates the leaf and branch motions based on "1/f(beta) noise", which is observed in various natural phenomena. For the branch motion, a simple simulation method based on the spring model is applied to enhance the realism of the motion. This method enables the real-time creation of the leaf and branch motions. Diverse motions according to tree species and shapes and wind conditions can be easily realized by controlling the parameters.

This paper surveys and investigates the strengths and weaknesses of a number of recent approaches to advanced workflow modelling. Rather than inventing just another workflow language, we briefly describe recent workflow languages, and we analyse them with respect to their support for advanced workflow topics. Object Coordination Nets, Workflow Graphs, WorkFlow Nets, and an approach based on Workflow Evolution are described as dedicated workflow modelling approaches. In addition, the Unified Modelling Language as the de facto standard in object-oriented modelling is also investigated. These approaches are discussed with respect to coverage of workflow perspectives and support for flexibility and analysis issues in workflow management, which are today seen as two major areas for advanced workflow support. Given the different goals and backgrounds of the approaches mentioned, it is not surprising that each approach has its specific strengths and weaknesses. We clearly identify these strengths and weaknesses, and we conclude with ideas for combining their best features. © 2003, IOS Press. All rights reserved.

Visualizing the artifacts of a software system graphically has proven to improve the cognitive strategies and understanding of the subject system by programmers. This is more crucial when they need to maintain a software system with out-dated documentation or without system documentation at all. Many tools have emerged and they predominantly consist of a reverse engineering environment and a viewer to visualize software artifacts such as in the form of graphs. The tools also grant structural redocumentation of existing software system but they do not directly utilize document-like software visualization in their approaches. We propose DocLike modularized graph (DMG) method that represents the software architectures of a reverse engineered subject system graphically in a modularized and standardized document-like manner. To realize this method, we have built a prototype tool called DocLike Viewer that enables a user to redocument, visualize and comprehend a subject system written in C language that is parsed by an existing parser. From the experiment conducted we found that our method managed to statistically improve cognition of a subject system in terms of productivity and quality to solve certain types of maintenance tasks.

The scale of software on digital AV appliances that handle large-volume multichannel digital data has been increased by the GUIs (graphical user interfaces) loaded on them in recent years. In addition, the GUIs of AV appliances use remote controls having cursor keys. Focus management must be performed by these to point to the object of operation, in contrast to the mouse, which is capable of pointing on the entire screen. Since focus management changes with changes in the specifications of GUIs, such as screen layouts and the like, software may not be reusable. In this paper, a development system that attempts to improve the productivity of GUI software requiring focus management is discussed from the points of view of (1) a software design model based on an object-oriented MVC model, (2) an execution model with good efficiency corresponding to the design model, (3) development tools performing synthesis of GUI software and automatic generation of focus management procedures, and (4) applications and evaluations of the system. In an example of the application of the system, software productivity with a GUI specification change was improved by a factor of three. © 2003 Wiley Periodicals, Inc.
