This paper addresses synchronization problem for discrete-time complex dynamical networks with interval time-varying delays. In order to achieve the synchronization, a feedback controller subjected to randomly occurring perturbations will be considered. The randomly occurring perturbations are assumed to belong to the Binomial sequence. By constructing a suitable Lyapunov–Krasovskii functional, and utilizing reciprocally convex approach and Finsler?s lemma, the synchronization criteria for the networks are established in terms of linear matrix inequalities (LMIs) which can be easily solved by various effective optimization algorithms. The networks are represented by the use of Kronecker product technique. The effectiveness of the proposed methods will be verified via numerical examples.  相似文献

劳伦斯小说创作的主题是男女之间的关系 ,其性爱理想是两性之间灵与肉的和谐交流 ,这与其生命哲学和性宗教思想息息相关。然而 ,他在小说中表现的男女之间的三种关系却与其性爱理想存在着深刻的悖论。因为劳伦斯性爱理想的实质是树立男性霸权地位并对女性的独立进行压制 ,这是与作者自身的特殊经历和当时的时代背景紧密联系的  相似文献

In the current age of managed care and evidence‐based treatments, play therapy has declined in popularity and prestige. Other treatments offer more concrete techniques and means of achieving measurable outcomes. They have been studied using randomized clinical trials, providing solid evidence that they are effective at treating particular diagnoses and symptoms. Although some preliminary evidence exists to back play therapy as an effective treatment for certain presenting problems, it lacks the evidence base of other treatments. Why, then, do child therapists still use play therapy?  相似文献

During an extensive conservation project in 2017, the National Trust, working with academics from Oxford, Southampton and Bangor Universities and drawing on research in the re‐enactment of medieval liturgy, experimented with a soundscape installation at The Vyne, a manor house near Basingstoke. Dealing with the challenge of telling a Tudor story without a contemporaneous collection, the soundscape deployed specially commissioned new recordings of Tudor polyphony and plainsong, spoken and intoned prayers, and Foley effects to simulate the celebration of Mass in The Vyne's pre‐Reformation chapel. The soundscape imagines a moment in 1535 when Henry VIII attended a Lady Mass, surveying the service from his position of power in the lord's chambers above the chapel. It places visitors at the heart of a politically‐charged time for both his religious reforms and his marriage, standing where his officers of the church would have stood as the liturgy and Nicholas Ludford's elaborate polyphonic music unfolded around them. Although the soundscape provides a model for using sound in immersive storytelling in fragile historic house environments, evidence of impact on visitors is limited by current evaluation methods commonly employed in the sector. This case study describes the rationale and construction of the soundscape, evaluates existing evidence for impact on visitors, and proposes alternatives for better evaluating historic house soundscapes.  相似文献

Collections can be a ‘mystery’ to many museum visitors, which makes investing in behind‐the‐scenes tours an opportunity for increasing awareness of the role museums play in scientific research. Drawing on the theories of contextual learning, situated learning, and legitimate peripheral participation, we offer insights from an exploratory study that investigated the potential effectiveness and practicalities of using behind‐the‐scenes tours to improve visitor understandings of museum research. This forum paper reports on emerging results from visitor questionnaires and staff interviews across six museums where we explored the experience offered by behind‐the‐scenes tours as an effective learning environment. These results suggest that behind the scenes tours remain under‐researched and highlight the need for further investigation into the value of this visitor experience.  相似文献
