Distributed systems consist of interconnected, lower-dimensional subsystems. For such systems, distributed analysis and design present several advantages, such as modularity, easier analysis and design, and reduced computational complexity. A special case of distributed systems is when the subsystems are connected in a string. Applications include distributed process control, traffic and communication networks, irrigation systems, hydropower valleys, etc. By exploiting such a structure, in this paper, we propose conditions for the distributed stability analysis of Takagi–Sugeno fuzzy systems connected in a string. These conditions are also extended to observer and controller design and illustrated on numerical examples. 相似文献

为探索多重条件并发对平台企业商业模式创新的影响,基于机会资源一体观构建商业模式创新路径模型,通过对193个样本进行模糊集定性比较分析发现:平台企业商业模式创新路径形成依赖机会开发和资源联动层面要素的组合;机会开发和资源联动层面不同要素的组合形成两类商业模式创新路径,类型1强调模仿型机会开发与资源联动策略组合,类型2强调创新型机会开发与资源联动策略组合;机会开发适配的资源联动方式存在差异,其中模仿型机会开发与资源共享和资源编排匹配良好,而创新型机会开发与资源编排、资源拓展匹配良好。研究结论揭示了平台企业商业模式创新多条等效路径,丰富了商业模式创新前因研究,也为平台企业商业模式创新实践提供了理论指导。 相似文献

The question of inclusive education is not straightforward. Despite all its good intentions, inclusive education, in practice faces numerous challenges today. This study analyses these challenges in the Swedish special education context. The author explores special educators’ experiences, possibilities and challenges when applying inclusive education. Findings reveal positive attitudes to the concept of inclusive classrooms. Nevertheless, teachers face more than a few grey areas that need to be put in place in order to achieve socially and cognitively inclusive classrooms. 相似文献

This study investigated the relative extent to which developing readers (6‐ and 9‐year‐olds) of English (deep) or Greek (transparent) orthography exhibit serial and exterior letter effects in letter position encoding. Participants were given a visual search task that required detection of a pre‐specified target letter within a random five‐letter string. Stimuli comprised letters either specific to English or Greek, or shared by both orthographies. For native letters, all readers showed significant initial‐letter facilitation. In contrast, final‐letter facilitation was shown only by English children. Furthermore, Greek 9‐year‐olds showed significantly more left‐to‐right facilitation than English 9‐year‐olds. These results suggest that letter position encoding is adaptive to the nature of the orthography acquired during reading development. 相似文献

The impact of electric overhead radiant heaters on the microclimate, air flows, transport and deposition of suspended particulate matter (SPM) was monitored between March 2004 and March 2005 in the historic churches of Saint Michael Archangel in Szalowa and Saint Catherine in Cracow (Poland). The measurements show that although irradiation at the floor level increases temperature and reduces relative humidity in the interior of the church, the effect out of the heated zone and for the surfaces sheltered from irradiation is very limited, i.e. their extent is comparable with natural fluctuations inherent to the local climate of the church. The radiant heaters proved to generate little convectional flow of the air. Therefore, the heating system was not found to increase the concentration of SPM indoors; in particular, no re-suspension of particles already present in the church was observed. This work has demonstrated that the overhead radiant heaters are capable of providing localised heat to the areas where people congregate without adversely affecting painted walls and the works of arts displayed in churches. Care, however, should be taken that sensitive works of art are not exposed to the direct infrared radiation. 相似文献

As part of their longitudinal investigations of a large cohort with a history of specific language impairment (SLI), Professor Gina Conti-Ramsden and her research team based at the School of Education, University of Manchester, Dr Emma Knox, Dr Nicola Botting and Dr Zoë Simkin report on the changing educational placements and National Curriculum assessment outcomes of 200 children at 11 years. Teacher questionnaires reporting on the Year 6 primary education placements of the sample reveal details about the long-term educational needs of children with SLI.
Furthermore, in exploring the experiences of the sample in the National Curriculum Key Stage 2 tests the present study found that children with SLI perform poorly relative to national expectations of levels of achievement across all tests. At present there are no guidelines for supporting children with SLI in relation to National Curriculum tests and the present data suggests there is an obvious need for these to be developed. 相似文献

In many engineering curricula a period of practical training in industry is either compulsory or advised. Often the educational goals of such a period are defined as 'learning to put knowledge and skills into practice'. The assessment is usually based on a technical report of the activities during the period. In this paper, how the definition of educational objectives led to the introduction of practical training is discussed. These objectives are acquiring insight in the engineering profession, learning to 'survive' in a different culture and learning to apply as well as broadening technical knowledge and skills. Furthermore, an assessment procedure is introduced which allows for testing whether the students have met the objectives. 相似文献
