This paper investigates simple syntactic methods for revising prioritized belief bases, that are semantically meaningful in the frameworks of possibility theory and of Spohn''s ordinal conditional functions. Here, revising prioritized belief bases amounts to conditioning a distribution function on interpretations. The input information leading to the revision of a knowledge base can be sure or uncertain. Different types of scales for priorities are allowed: finite vs. infinite, numerical vs. ordinal. Syntactic revision is envisaged here as a process which transforms a prioritized belief bases into a new prioritized belief base, and thus allows a subsequent iteration.

Which gates are universal for quantum computation? Although it is well known that certain gates on two-level quantum systems (qubits), such as the controlled-not, are universal when assisted by arbitrary one-qubit gates, it has only recently become clear precisely what class of two-qubit gates is universal in this sense. We present an elementary proof that any entangling two-qubit gate is universal for quantum computation, when assisted by one-qubit gates. A proof of this result for systems of arbitrary finite dimension has been provided by Brylinski and Brylinski; however, their proof relies on a long argument using advanced mathematics. In contrast, our proof provides a simple constructive procedure which is close to optimal and experimentally practical. © 2002 The American Physical Society.

Simulations and universal quantum computations using an entangling Hamiltonian and local unitaries were performed. A specific two-qubit example was given to illustrate the techniques and the general algorithm was described for the case of an arbitrary two-qubit systems. The efficiency of the algorithm and the effect of errors were then discussed.

We prove frame determination results for the family of many-valued modal logics introduced by M. Fitting in the early ́90s. Each modal language of this family is based on a Heyting algebra, which serves as the space of truth values, and is interpreted on an interesting version of possible-worlds semantics: the modal frames are directed graphs whose edges are labelled with an element of the underlying Heyting algebra. We introduce interesting generalized forms of the classical axioms D, T, B, 4, and 5 and prove that they are canonical for certain algebraic frame properties, which generalize seriality, reflexivity, symmetry, transitivity and euclideanness. Our results are quite general as they hold for any modal language built on a complete Heyting algebra.

Future broadband integrated services networks based on asynchronous transfer mode (ATM) technology are expected to support multiple types of multimedia information with diverse statistical characteristics and quality of service (QoS) requirements. To meet these requirements, efficient scheduling methods are important for traffic control in ATM networks. Among general scheduling schemes, the rate monotonic algorithm is simple enough to be used in high-speed networks, but does not attain the high system utilization of the deadline driven algorithm. However, the deadline driven scheme is computationally complex and hard to implement in hardware. The mixed scheduling algorithm is a combination of the rate monotonic algorithm and the deadline driven algorithm; thus it can provide most of the benefits of these two algorithms. In this paper, we use the mixed scheduling algorithm to achieve high system utilization under the hardware constraint. Because there is no analytic method for schedulability testing of mixed scheduling, we propose a genetic algorithm-based neural fuzzy decision tree (GANFDT) to realize it in a real-time environment. The GANFDT combines a GA and a neural fuzzy network into a binary classification tree. This approach also exploits the power of the classification tree. Simulation results show that the GANFDT provides an efficient way of carrying out mixed scheduling in ATM networks.

A neural fuzzy system learning with fuzzy training data is proposed in this study. The system is able to process and learn numerical information as well as word information. At first, we propose a basic structure of five-layered neural network for the connectionist realization of a fuzzy inference system. The connectionist structure can house fuzzy logic rules and membership functions for fuzzy inference. The inputs, outputs, and weights of the proposed network can be fuzzy numbers of any shape. Also they can be hybrid of fuzzy numbers and numerical numbers through the use of fuzzy singletons. Based on interval arithmetics, a fuzzy supervised learning algorithm is developed for the proposed system. It extends the normal supervised learning techniques to the learning problems where only word teaching signals are available. The fuzzy supervised learning scheme can train the proposed system with desired fuzzy input-output pairs. An experimental system is constructed to illustrate the performance and applicability of the proposed scheme. © 2002 Elsevier Science B.V. All rights reserved.

This paper discusses the problem of automatic word boundary detection in the presence of variable-level background noise in cars. Commonly used robust word boundary detection algorithms always assume that the background noise level is fixed and sets fixed thresholds to find the boundary of word signal. In fact, the background noise level in cars varies in the procedure of recording due to speed change and moving environment, and some thresholds should be tuned according to the variation of background noise level. This is the major reason that most robust word boundary detection algorithms cannot work well in the condition of variable background noise level. To solve this problem, we propose a minimum mel-scale frequency band (MiMSB) parameter which can estimate the varying background noise level in cars by adaptively choosing one band with minimum energy, from the mel-scale frequency bank. With the MiMSB parameter, some preset thresholds used to find the boundary of word signal are no longer fixed in all the recording intervals. These thresholds will be tuned according to the MiMSB parameter. We also propose an enhanced time-frequency (ETF) parameter by extending the time-frequency (TF) parameter proposed by Junqua et al. from single band to multiband spectrum analysis, where the frequency bands help to make the distinction between speech signal and noise. The ETF parameter can extract useful frequency information by choosing some bands of the mel-scale frequency bank. Based on the MiMSB and ETF parameters, we finally propose a new robust algorithm for word boundary detection in variable noise-level environment. The new algorithm has been tested over a variety of noise conditions in cars and has been found to perform well not only under variable background noise level condition, but also under fixed background noise level condition. The new robust algorithm using the MiMSB and ETF parameters achieved higher recognition rate than the TF-based robust algorithm, whi...

This paper addresses the problem of speech segmentation and enhancement in the presence of noise. We first propose a new word boundary detection algorithm by using a neural fuzzy network (called ATF-based SONFIN algorithm) for identifying islands of word signals in fixed noise-level environment. We further propose a new RTF-based RSONFIN algorithm where the background noise level varies during the procedure of recording. The adaptive time-frequency (ATF) and refined time-frequency (RTF) parameters extend the TF parameter from single band to multiband spectrum analysis, and help to make the distinction of speech and noise signals clear. The ATF and RTF parameters can extract useful frequency information by adaptively choosing proper bands of the mel-scale frequency bank. Due to the self-learning ability of SONFIN and RSONFIN, the proposed algorithms avoid the need of empirically determining thresholds and ambiguous rules. The RTF-based RSONFIN algorithm can also find the variation of the background noise level and detect correct word boundaries in the condition of variable background noise level by processing the temporal relations. Our experimental results show that both in the fixed and variable noise-level environment, the algorithms that we proposed achieved higher recognition rate than several commonly used word boundary detection algorithms and reduced the recognition error rate due to endpoint detection.

In this paper, we propose a global optimal fuzzy tracking controller, implemented by fuzzily blending the individual local fuzzy tracking laws, for continuous and discrete-time fuzzy systems with the aim of solving, respectively, the continuous and discrete-time quadratic tracking problems with moving or model-following targets under finite or infinite horizon (time). The differential or recursive Riccati equations, and more, the differential or difference equations in tracing the variation of the target are derived. Moreover, in the case of time-invariant fuzzy tracking systems, we show that the optimal tracking controller can be obtained by just solving algebraic Riccati equations and algebraic matrix equations. Grounding on this, several fascinating characteristics of the resultant closed-loop continuous or discrete time-invariant fuzzy tracking systems can be elicited easily. The stability of both closed-loop fuzzy tracking systems can be ensured by the designed optimal fuzzy tracking controllers. The optimal closed-loop fuzzy tracking systems cannot only be guaranteed to be exponentially stable, but also be stabilized to any desired degree. Moreover, the resulting closed-loop fuzzy tracking systems possess infinite gain margin; that is, their stability is guaranteed no matter how large the feedback gain becomes. Two examples are given to illustrate the performance of the proposed optimal fuzzy tracker design schemes and to demonstrate the proved stability properties.

Following a Capability Maturity Model (CMM) mini-assessment, the organization is undertaking significant changes in the requirements management process, which include the introduction of group session approaches to requirements analysis and a structured method for writing requirements. An empirical evaluation of the process improvement indicates tangible benefits as well as perceived long-term benefits during design and testing. Findings suggest that a more thorough requirements analysis results in more clearly defined, better understood and specified requirements, and an enhanced ability to address the market needs and product strategy requirements. The catalyst behind these improvements includes project management leadership, managing the human dimension, collaboration among stakeholders and senior management support.

Architecture is a central concept in the engineering of computer based systems. Given a standard architectural representation, the architecture of systems can be discussed, drawn, reasoned about and classified. Complex architectures may benefit from visualisation. Currently, tools that visualise architectures do so in two-dimensions. Above and beyond visualising the form (or structure) of the architecture in three dimensions, other characteristics of the architecture (e.g. Modularity, Performance, Evolvability, and Openness) can be shown through the visualisation. This paper focuses on the "drawing" of architectures or what is referred to as Architectural Visualisation.

Formalising a measurement is often preceded by rich discussion of the ideas, and the development of general understanding of the meaning of concepts, often over decades. As a consequence, data required to fit into a representational measurement system is usually readily available and there is a general acceptance of the intention of the measure. This paper reports on a research project which has formalised the measurement of a relatively new body of knowledge, open systems. Open systems rely on standards to guarantee interoperability, portability, scalability and user portability. The Internet is the most successful of the open systems in existence, in terms of interoperability and scalability. The first of four issues was that since the project was a research contract, and because there were very few generally understood notions of measurement foundations (or relations) within open systems, the aims and the requirements of the measurement were formalised into a measurement requirements specification (MRS). A second issue concerns the building of a relational model. Building relations in a representational measurement model is relatively straightforward in the case where the measurement entity has been around. A third issue concerned the use of the measures when the measures were (not surprisingly) complex, and had to be combined by biased combiners, the values of which not all parties would naturally agree. A fourth issue raised in the paper is the extent of the validation of the measures which was required because of the contract.

This method contains the multiband analysis and a neural fuzzy network, and it achieves higher recognition rate than the TF-based robust algorithm by 5%. In addition, a new speech segmentation method called RTF-based RSONFIN algorithm is proposed for variable noise-level environment. The RTF-based RSONFIN algorithm contains a recurrent neural fuzzy network. This method contains the multiband analysis and achieve higher recognition rate than the TF-based robust algorithm by 12%.

The designed system consists of a tonometer, a micro syringe device, and a model-based fuzzy logic controller. The proposed control system consists of a linear predictor, and a synthetic fuzzy logic controller (SFLC). The design of the fuzzy rules in each subcontroller is based on the oscillometric principle saying that the arterial vessel has the maximum compliance when the detected vessel volume pulse reaches its maximum amplitude.

Organizations invest in B2B and workflow management systems to enable seamless integration of multiple transaction systems that support their business processes. However, knowledge of the organization's performance becomes buried within internal processing of the B2B workflow platform. This research introduces a framework that analyses workflow audit logs, utilizing DSS principles together with agent technologies, to feedback the organization's performance measures. We apply this framework to a private trading exchange case study where suppliers participate in an interorganizational order fulfillment workflow. Agents refine the organization's knowledge of supplier productivity and commitment as they learn from interactions over time with trading partners

© 2002 IEEE. Organisations are re-engineering their B2B communications to be performed through web services. Their aim is to create modularised services that support the business processes within their organisation and also those external entities that participate in these same business processes. This improvement is at the expense of the organisation's knowledge of its performance, as this knowledge will become buried within the internal processing of the web service platform. This research introduces an approach to reclaim and improve this knowledge for the organisation by establishing a framework that enables the definition of web services, together with the logging and analysis of the enactment of web services. This framework utilises web service concepts, DSS principles, and agent technologies, to enable feedback on the organisation's performance measures through the analysis of the web services. We apply this framework to a specific case study where suppliers participate in an inter-organisational workflow via a Private Exchange in the context of order fulfilment. A key benefit of this work is that the data is stored once but provides information both to the organisation acting as the customer and the organisation acting as the supplier. It therefore removes the need for development of internal performance monitoring tools to monitor web services performance.

© 2002 IEEE. Neonatal intensive care units (NICUs) require equipment and facilities to assist and monitor premature (and some full-term) babies. This equipment outputs physiological and clinical data, but current research does not provide doctors with techniques for capturing this data in a format that is suitable for analysis and research. Additionally, regional hospitals provide limited NICU support, but, without access to a neonatologist, the baby must be moved to another hospital. This paper details a framework for clinical and physiological data capture, the storage structures within the e-Baby data warehouse, and information access through a secure intranet/Internet browser. The key contribution of this work is the infrastructure that provides a platform for patient information data capture, storage, display and analysis. A key benefit of this work is to provide a mechanism for neonatologists to receive information directly from a regional hospital, thereby preventing, in some cases, the immediate need to move the baby.

We describe a new method for the visualization of tree structured relational data. It can be used especially for the display of very large hierarchies in a 2-dimensional space. We discuss the advantages and limitations of current techniques of tree visualization. Our strategy is to optimize the drawing of trees in a geometrical plane and maximize the utilization of display space by allowing more nodes and links to be displayed at a limit screen resolution. We use the concept of enclosure to partition the entire display space into a collection of local regions that are assigned to all nodes in tree T for the display of their sub-trees and themselves. To enable the exploration of large hierarchies, we use a modified semantic zooming technique to view the detail of a particular part of the hierarchy at a time based on user's interest. Layout animation is also provided to preserve the mental map while the user is exploring the hierarchy by changing zoomed views.

The design of Web sites has been largely ad hoc, with little concern about the effectiveness of navigation and maintenance. This paper presents a general framework with a human-Web interface that supports Web design through visual programming and reverse Web engineering through visualization. The paper describes the framework in the context of a Web tool, known as HWIT which has been developed for a pilot study.
