With the rapid development of China’s economy, the scale of the city has been continuously expanding, industrial enterprises have been increasing, the discharge of multiple pollutants has reached the top of the world, and the environmental problems become more and more serious. The air pollution problem is particularly prominent. Air quality has become a daily concern for people. In order to control air pollution, it is necessary to grasp the air quality situation in an all-round way. It is necessary to evaluate air quality. Accurate results of air quality evaluation can help people know more about air quality. In this paper, refers to previous research results and different evaluation methods, combined with artificial neural network, fuzzy theory, genetic algorithm, GA-BP hybrid algorithm based on fuzzy theory is proposed to evaluate air quality. At the same time, for the problem that the two-grade standard of air quality annual evaluation is not suitable for practical application, the four-grade standard for annual air quality evaluation has been proposed, and its practicality has been verified through experiments. By setting contrast experiments and comparing the air quality evaluation model based on standard BP algorithm, it is proved that the fuzzy GA-BP evaluation model is better than the standard BP model, both in efficiency and accuracy.  相似文献

This is the third year in which a team from University College Dublin has participated in the Multi-Agent Programming Contest (http://www.multiagentcontest.org/2010). This paper describes the system that was created to participate in the contest, along with observations of the team??s experiences in the contest. The system itself was built using the AF-TeleoReactive and AF-AgentSpeak agent programming languages running on the Agent Factory platform. A hybrid control architecture inspired by the SoSAA strategy aided in the separation of concerns between low-level behaviours (such as movement and obstacle evasion) and higher-level planning and strategy.  相似文献

Decision-making is a complex and demanding process often constrained in a number of possibly conflicting dimensions including quality, responsiveness and cost. This paper considers in situ decision making whereby decisions are effected based upon inferences made from both locally sensed data and data aggregated from a sensor network. Such sensing devices that comprise a sensor network are often computationally challenged and present an additional constraint upon the reasoning process. This paper describes a hybrid reasoning approach to deliver in situ decision making which combines stream based computing with multi-agent system techniques. This approach is illustrated and exercised through an environmental demonstrator project entitled SmartBay which seeks to deliver in situ real time environmental monitoring.  相似文献

The office automation marketplace is crowded with suppliers purveying very similar products, resulting in great confusion for first-time buyers. The paper suggests that buyers often ask the same questions. The reasons for asking these questions, and the likely answers, are discussed in detail. A number of suggestions which may guide buyers in their pursuit of a system which meets their requirements are also presented.  相似文献

Item response theory was used to investigate the functioning of the Psychopathy Checklist-Revised (PCL-R; R. D. Hare, 1991, 2003) in several offender populations. With male criminal offenders (N=3,847) as a reference group, differential item functioning analyses were performed for 3 comparison groups: female criminal offenders (N=1,219), male forensic psychiatric patients (N=1,246), and male criminal offenders scored from file reviews (N=2,626). Results are discussed in the context of the 2-factor, 4-facet model for the PCL-R (R. D. Hare, 2003; J. Parker, G. Sitarenios, & R. D. Hare, 2003). Application of a multigroup graded response model to all 4 groups suggests scalar equivalence may hold at least approximately for each population, although the PCL-R provided slightly greater information about the latent trait of psychopathy for male criminal offenders scored from the standard procedure.

M. S. Lewis and P. A. Griffin (see record 1981-21450-001) explained the season of birth effect in schizophrenia in terms of an epidemiological artifact, and they proposed a method of correction for this, based on the hypothesis of an age-prevalence effect. The present authors applied Lewis and Griffin's method in analyzing the birth-month distribution of 11,728 schizophrenic patients first admitted to hospitals in England and Wales between 1970 and 1974. Even when thus corrected, the birth distribution of the schizophrenics remained significantly different from that of the controls. In addition, when July was taken as the 1st mo of the year, the predictions of their hypothesis were not confirmed. It is argued that this hypothesis does not accord with clinical experience and that its consequences cannot be easily reconciled with many of the reported birth distributions of schizophrenia. It is concluded that the age-prevalence effect, as defined by Lewis and Griffin, does not provide any straightforward explanation for the season of birth effect in schizophrenia.

Significant negative correlations were obtained between scores on Byrne's Repression-Sensitization (R-S) scale and several indices of electrodermal activity in a paradigm in which Ss anticipated the presentation of strong electric shock. These results support the hypothesis that Ss who receive low scores on the R-S scale (repressers) exhibit greater disturbance than do those who receive high scores (sensitizers). Repressers reported a stronger tendency to avoid thinking about impending shock (suppression) than did sensitizers. This reported tendency to use suppression techniques was directly and significantly related to basal skin conductance, non-specific GSR activity, magnitude of anticipatory GSR activity, and the number of sec. by which this activity preceded shock.

Utilized a delayed, differential paradigm to investigate electrodermal, cardiac, and vasomotor conditioning in 18 psychopathic, 18 nonpsychopathic, and 18 "mixed" inmates. 3 tones, each 10 sec. long, were presented 16 times each in random order, alone, or followed by a shock or slide of a nude female. The psychopaths gave very little evidence of differential electrodermal conditioning. However, they acquired differential cardiac and digital vasomotor responses just as readily as did the nonpsychopaths to the CS followed by shock or by slides. Neither group gave any evidence of differential cephalic vasomotor conditioning. The psychopaths exhibited a lower level of tonic electrodermal activity and were less electrodermally responsive than were the other Ss. There were no differences between groups in tonic heart rate or in cardiac or digital vasomotor responsivity. However, the psychopaths responded to shock with cephalic vasodilation while the nonpsychopaths responded with vasoconstriction. (34 ref.)
