Because of the pneumatic system’s compressibility and few stop positions, it was considered hard to control in a precise motion control system. With the help of newly developed pneumatic servo control technology, using servo-pneumatic positioning controller now is just as easy as using electro-servo system. This article discusses Web-based servo-pneumatic manipulator control and object recognition and positioning. The authors built a three-degrees-of-freedom (3 DOF) pneumatic manipulator with a servo-pneumatic closed-loop control system and machine vision system in their lab. Web-based tele-operation was a basic ability in this experimental system. After installing a CCD camera, video capture card, and related software developed by the authors, the robot could recognize the user specified object through the Web page and find its position. The remote user could command the robot to move to the position and to grab the object. The critical issues of Web-based control are to integrate hybrid open-architecture mechatronic system through the Web and develop a software language environment characterized by the script. The authors’ experiment showed that pneumatic devices could serve as accurate position control and be controlled through the Web.展开更多

On the basis of the 4-layered SOA-SDI framework, WebGIS applications can be quickly deployed, which proves that SOA-SDI has the potential to reduce the input of software development and shorten the development period.展开更多

文摘The 13-node quadrilateral and 39-node hexahedral cubic serendipity elements produce nodally integrated positive-definite lumped heat capacity matrices in higher-order finite element analysis.However,these elements display severe convergence deterioration in explicit transient heat conduction analysis with lumped heat ca-pacity matrices.This convergence decay is due to the violation of variational integration consistency by the standard Galerkin formulation with lumped heat capacity matrices.This issue is resolved by introducing the boundary-enhanced Galerkin weak form that incorporates the elemental boundary contribution in the discrete finite element formulation.Subsequently,it is theoretically proven that a direct nodal integration identically fulfills the variational integration consistency in the context of the boundary-enhanced Galerkin weak form.The proposed variationally consistent nodal integration therefore enables optimal convergence for explicit transient heat conduction analysis with lumped heat capacity matrices.The efficacy of the proposed variationally con-sistent nodal integration formulation for the 13-node quadrilateral and 39-node hexahedral cubic elements is thoroughly demonstrated via numerical examples.
文摘Mason Reset(MR),a groundbreaking invention by Clesson E.Mason in 1930 that later became a part of“the universal approach to process control instrumentation”,is revisited in this paper and is shown to consists of three actions:fast(errorcorrection),medium(negative feedback for expanded proportional band)and slow(reset for zero steady-state error).The focus of the paper is on the reset action,generated from a positive feedback loop,and its underlying principles with profound implications to our understanding and practice of automatic control,both basic and advanced.For example,we note that reset control and integral control,contrary to common belief,differ fundamentally in design principle and in practicality.Such difference comes to a head in the event of integrator windup:while reset windup is a problem of actuator saturation,the integrator windup is a runaway situation due to controller instability.In fact,there is no advantage gained in replacing MR with an integrator.In other words,one should not integrate the error directly as in standard PID,since doing so makes the closed-loop system internally unstable.With MR-based control formulated in this paper,there is no such threat of instability and,therefore,no need for any anti-windup mechanisms.Furthermore,the integral control is made scalable in this framework as a tradeoff between the steady-state accuracy and the controller stability.This leads to a novel MR-based control design,scalable in gain and in time to accommodate various process characteristics and design specifications.Simple in construction and transparent in principle,this MR-based control,as a basic framework of design,is readily deployable in scale.
文摘China and ASEAN have emerged as close partners in the digital economy,with extensive cooperation in key areas such as digital infrastructure,5G technology,artificial intelligence,and big data.The comprehensive implementation of the Regional Comprehensive Economic Partnership(RCEP)has provided institutional guarantees and regulatory benefits for China-ASEAN digital economic collaboration.This framework has enhanced the marginal effects of their digital economies,unlocked the potential of the digital market,and facilitated digital transformation and regional socio-economic development.Nevertheless,challenges remain,including the incomplete harmonization of trade rules and standards among ASEAN member states,uneven development of digital infrastructure,and the increasingly complex landscape of digital economic cooperation.To address these issues,future efforts should focus on creating a more conducive digital environment,accelerating the construction of digital infrastructure,fostering industrial innovation and complementary development,and promoting cross-sectoral collaboration in digital services.
文摘The integration of education,technology,and talent is a strategic institutional arrangement for China to build a high-quality education system and achieve innovation-driven development in the new era.As the main platform for cultivating technical and skilled talents,vocational education faces dilemmas such as ambiguous role positioning,conflicting role expectations,and insufficient role capabilities when it comes to the coupling of the three functions of“education-technology-talent”.Based on the analytical framework of role theory and structural functionalism,this paper proposes three paths:clarifying role positioning through the integration of vocational and general education,reconstructing role expectations through the integration of science and education,and enhancing role capabilities through the integration of industry and education.These paths provide theoretical references and practical guidance for optimizing the function of vocational education in the collaborative innovation system.
文摘As a crucial pivot for national strategic development,the university relocation project in Xiong’an New Area undertakes the mission of optimizing capital functions and promoting regional coordinated development.Taking the Xi-ong’an Campus of China University of Geosciences(Beijing)as a case study,this paper explores the collaborative pa-thways between universities and cities in terms of functional complementarity,resource sharing,and ecological symbiosis from the perspective of campus functional layout and spatial optimization.By integrating four core concepts—green ecology,intelligent technology,cultural inheritance,and traffic optimization—it proposes a design strategy of“breaking boundaries and multi-dimensional linkage,”aiming to construct a new spatial paradigm of urban-university integration and provide theoretical support and practical references for the development of higher education and urbanization in Xiong’an New Area.
