3D技术教育应用创新透视

3D技术是虚拟现实、实时仿真和交互三维设计结合产生的关键技术,包括3D显示技术、3D虚拟现实技术和3D打印技术。目前3D技术已成为桌面技术(3D显示技术和3D虚拟现实技术为桌面显示技术,3D打印技术为桌面制造技术),正逐渐在知识创新、深度学习、虚拟实验、技能训练等方面彰显优势,为教育应用创新提供新环境、新平台、新资源、新工具和新范式。然而由于产品价格较为昂贵,后续的保养、管理及维修等费用也较高,3D技术教育应用在顶层设计、技术支持、教育资源、测评标准、应用领域、人才培养等方面仍面临较多困难。3D技术教育应用是一个教育生态系统,是依托3D技术、资源、工具、平台、产品、人才和课程,构建教学资源、教学媒体和教学产品的设计、开发、运用、管理和评价的教育系统,需要进行理论、技术与应用的协同推进,从生态发展、产业推进、深度融合视角开展研究。在落实《教育信息化十年发展规划(2011-2020年)》之际,应将"3D技术教育应用创新"作为技术与教育"深度融合"的重要途径,构建3D教育应用生态系统环境,促进教学方式与学习方式变革,以此应对第三次工业革命带来的机遇和挑战。

公平与效率视野下的城市体育空间分异的八个问题研究

本文从公平与效率视角出发,以问题为引导,探讨了城市体育空间分异的概念、理论依据、分类特征、驱动机制以及应对策略等议题,关注如何通过城市体育空间的公平配置与高效供给,推进城市体育空间建设和优化的科学性。研究认为：城市体育空间分异是城市体育空间在自然地理、经济、政治、社会等主要影响因素的相互作用下,经过城市选择性更新与滤出、土地出让与住房制度变迁、城市扩张与房地产发展、体育产业化与商业化运营、城市发展的历史惯性与累积等一系列社会活动作用下产生的。它呈现出了资本化分异、人口分异、空间可达性分异、与城市空间结构契合性分异等特征。提出了行政规划制度化、用地政策公平导向性、供给方式差异化、供给主体多元化、公共交通可达性的应对策略。

Finite-time synchronization of drive-response systems via periodically intermittent adaptive control

In this paper, the finite-time synchronization between two complex dynamical networks via the periodically intermittent adaptive control and the periodically intermittent feedback control is studied. The finite-time synchronization criteria are derived based on finite-time stability theory, the differential inequality and the analysis technique. Since the traditional synchronization criteria for some models are improved in the convergence time by using the novel periodically intermittent adaptive control and periodically intermittent feedback control, the results of this paper are important. Numerical examples are finally presented to illustrate the effectiveness and correctness of the theoretical results.     

Finite-time control for soft landing on an asteroid based on line-of-sight angle

Motivated by the requirement for safe and pinpoint soft landing in future asteroids missions, a soft landing control method based on finite-time control (FTC) technique is developed in this paper. Firstly, in order to utilize the design philosophy of cascaded system, the landing error dynamics of asteroid probe are divided into two subsystems, including a position error subsystem (PES) and a line-of-sight angle error subsystem (LOSAES). Secondly, homogeneous system theory is employed to design the control law for LOSAES such that the states of LOSAES will be stabilized to the origin in finite time. For the reduced PES subsystem, a FTC law is designed such that the rest of states will converge to zero in finite time. Strict analysis shows that the whole system satisfies the finite time stability. Simulation results demonstrate that the proposed method provides faster convergence rates and better disturbance rejection properties compared with the traditional asymptotically stable control (ASC) method.     

Academic scientists’ affiliation with university research centers: Selection dynamics

University research centers have been institutionalized as a part of the science policy repertoire committed to strategic use of science and technology. Based on a representative sample of academic scientists and engineers in American research universities, this study investigates the selection dynamics, attempting to unfold the determinants of department-affiliated faculty members to be center affiliates. The findings suggest that university research centers select their affiliates on the basis of individual scientific and technical human capital. Scientists from prestigious departments are more likely to be center affiliates, so are prolific scientists, former postdoctoral scholars and the elder cohorts. In the meantime, university research centers are able to overcome the incentive incongruity with academic departments, as is evidenced by a higher likelihood among junior scientists to secure center connections. Dedicated to diversity and equity, university research centers provide a level playing field for women, minority and foreign-born scientists. The study concludes with a discussion of the scientific and technical human capital theory and policy implications in the science enterprise.
