基于MAS的混合智能故障诊断模型研究

针对复杂设备故障的复杂性和不确定性等特点,以起重设备为研究对象,提出了一种基于多Agent的混合智能故障诊断模型,并构建了模型的诊断工作过程及每一功能Agent的内部结构和功能。模型根据各子系统并行感知外界环境,动态地组建Agent诊断组,共同完成诊断任务。最后,通过实例验证了模型的有效性。该模型在某企业的设备远程维护平台应用中,能快速、准确地进行故障成因分析,并给出合理的决策意见,提高了设备的安全运行效率。     

‘The girls are out there’: professional perspectives on potential changes in the diagnostic process for,and recognition of,autistic females in the UK

There is widely growing recognition of autism in girls, and both researchers and community members have called for improvements in the diagnostic process. What is not yet known is whether these recommendations are being taken up by professionals. In this study, nine semi-structured interviews were conducted with a variety of professionals involved in the autism diagnostic process. The collected data were analyzed using thematic analysis. Three main themes were identified: gendered differences; lack of services; and informal change. Our study found that diagnostic professionals are aware of gender differences in presentation, and they make a range of informal adaptations to their processes for girls. While this is positive for those girls who interact with knowledgeable professionals, our data highlight the need for more systematic changes to ensure equality of access to diagnosis and post-diagnostic support.     

Characterization of aerobically fit individuals with cardiovascular disease

Abstract

With an ageing population there is an increased prevalence of individuals living with cardiovascular disease (CVD). Characteristics of older aerobically fit individuals with previously diagnosed CVD have not been studied. Therefore, our knowledge is limited as to how, or if, aerobically fit individuals with CVD attempt to adapt their physical activity and the intensity of their training programmes. The objective of this paper is to characterise the physical activity habits and behaviours of older aerobically fit individuals with CVD. We identified 28 aerobically fit patients with CVD from those who completed a minimum of 15 and 12 min of the Bruce treadmill protocol for men and women, respectively. Consenting participants responded to questionnaires regarding physical activity levels, competitive event participation and self-monitoring since diagnosis of heart disease. Average age and treadmill time of participants were 56 and 49 years and 15.6 and 13.0 min for males and females, respectively. Data were obtained regarding recent medical history (medical diagnoses, surgeries/procedures). Despite the majority of individuals participating in the same or more activity since their diagnosis, 25% indicated that their condition limited their activity and 39% reported having symptoms during activity. Nearly all participants (93%) indicated that they monitored their heart rate during exercise. However, only 14% of participants stated that their physician advised them on how to exercise safely. It is necessary for physicians and cardiac rehabilitation programmes to be involved in safe and effective exercise programming to allow individuals to return to sport after CVD.
