4281   A software application for possibilistic fuzzy diagnosis in complex systems A software application for possibilistic fuzzy diagnosis in complex systems    2009 This paper discusses a knowledge-base encoding methodology for diagnostic tasks. It transform. "expert"-provided rules into algebraic expressions so inference of the "possible" disorders is carried out via associated constrained optimisation problems. In this way, the need of conventional fuzzy inference systems or "uncertain"-logic schemes is no longer present in the particular setting in this paper. The problem is solved by efficient linear programming tools, in principle able to cope with lar... 查看全文

4282   Wavelet and self-constructing compensatory based fault diagnosis Wavelet and self-constructing compensatory based fault diagnosis    2005 A new self-constructing fuzzy wavelet neural networks (SCFWNN) using compensatory fuzzy operators are proposed for intelligent fault diagnosis in this paper. Hybrid intelligent systems, fuzzy wavelet neural networks possess the advantages of both wavelet networks and fuzzy rule-based systems and are particularly powerful in handling complex, non-linear and imprecise problems such as fault diagnosis. Two phases of learning, structure and parameter learning, are used for constructing the neurofuzz... 查看全文

4284   Specification and computing states in fuzzy algorithms Specification and computing states in fuzzy algorithms    2008 Since many complex decision making problems can be solved solely by means of an appropriate algorithm, checking the quality of such algorithm is a key issue, even more relevant in the presence of fuzzy uncertainty. In this paper we postulate that the design and formal specification of algorithms can be translated into a fuzzy framework introducing fuzzy first order logic and assert transformations. Following the classical crisp scheme we first formalize the concepts of a fuzzy algorithm specific... 查看全文

4285   Fusing fuzzy association rule-based classifiers using sugeno integral with ordered weighted averaging operators Fusing fuzzy association rule-based classifiers using sugeno integral with ordered weighted averaging operators    2007 The time or space complexity may considerably increase for a single classifier if all features are taken into account. Thus, it is reasonable to train a single classifier by partial features. Then, a set of multiple classifiers can be generated, and an aggregation of outputs from different classifiers is subsequently performed. The aim of this paper is to propose a classification system with a heuristic fusion scheme in which multiple fuzzy association rule-based classifiers with partial feature... 查看全文

4291   A hardware model for fuzzy temporal knowledge representation A hardware model for fuzzy temporal knowledge representation    2003 Fuzzy systems implemented in hardware operate with much higher performance than software implementations, and are more suitable for implementation in automated supervision systems. For systems with very strict temporal restrictions, those systems should be able to handle imprecise and uncertain information and should be capable of describing the evolution of the system in terms of a state change. This paper presents a hardware model capable of fuzzy temporal knowledge representation and reasonin... 查看全文

4292   Neural fuzzy approach for fuzzy system design Neural fuzzy approach for fuzzy system design    1997 A new class of neural fuzzy network based on a general neuron model is introduced in this paper. The network encodes a fuzzy rule base in its structure and process data according to fuzzy reasoning schemes. It learns membership functions for each input variable and rules covering the whole input/output space. These are important decisions when designing fuzzy systems. Due to its structure the fuzzy rules encoded are trivially and explicitly recovered. The network is also shown to have the univer... 查看全文

4298   Australian firefighters' exposure to air toxics during bushfire burns of autumn 2005 and 2006 Australian firefighters' exposure to air toxics during bushfire burns of autumn 2005 and 2006    2009 Bushfire fighting is a hazardous occupation and control strategies are generally in place to minimize the hazards. However, little is known regarding firefighters' exposure to bushfire smoke, which is a complex mixture of toxic gases and particles. In Australia, during the prescribed burning season, firefighters are likely to be exposed on a regular basis to bushfire smoke, but whether these exposures affect health has yet to be determined. There are a number of factors that govern whether expos... 查看全文

Traffic assignment is formulated as an optimization problem considering travel cost and on-road emissions. It introduces a cell-based approach to model emission concentrations so that either the average or maximum emissions in a network can be considered in the optimization process. The emissions in a cell are modeled taking into consideration the influence of the emission sources from all ... 查看全文

4302   Fuzzy PD-like scheme for two underactuated planar mechanisms Fuzzy PD-like scheme for two underactuated planar mechanisms    2000 In this paper, a two-rule-based fuzzy PD-like scheme is applied to swinging-up and then stabilize two mechanisms at unstable open-loop equilibrium states. The mechanisms are the so-called pole-cart system and the Pendubot. In both cases the fuzzy PD-like scheme is derived from non-complete sets of linguistic rules that links some mechanism states to the sign of a single control action. A simplified Tsukamoto's reasoning method and quasi-linear-mean aggregating operators are used to derive and an... 查看全文

The scheme is based on the modification of the Petri nets called Fuzzy Time Petri Nets (FTPN) and fuzzy temporal relations. The reasoning process uses the modified Petri nets theory, the possibility theory and a fuzzified version of Allen's temporal relations. The temporal linguistic expressions are modelled by primitives derived from the knowledge representation scheme. By combining and connecting these primitiv... 查看全文

Avoidance or minimization of pollution at the source prior to release to the environment is the objective of these regulations. This article describes an approach that can help chemical process industry (CPI) firms to take the first steps toward developing effective pollution prevention strategies using the information they are alread... 查看全文

4310   Children's pollutant exposure during school bus commutes Children's pollutant exposure during school bus commutes    2004 A real-time and integrated measurements of pollutant concentrations were investigated in diesel school buses to determine the range of children's exposures during their bus commutes. The exposures resulted primarily from the commute itself and not from loading, unloading or waiting at bus stops. The rear of the bus with windows closed tended to have higher pollutant concentrations, which appear to originate from self-pollution. The use of cleanest buses for the longest routes and minimizing the ... 查看全文
