文摘As coal mining progresses to greater depths,controlling the stability of surrounding rock in deep roadways has become an increasingly complex challenge.Although four-dimensional(4D)support theoretically offers unique advantages in maintaining the stability of rock mass,the disaster evolution processes and multi-source information response characteristics in deep roadways with 4D support remain unclear.Consequently,a large-scale physical model testing system and self-designed 4D support components were employed to conduct similarity model tests on the surrounding rock failure process under unsupported(U-1),traditional bolt-mesh-cable support(T-2),and 4D support(4D-R-3)conditions.Combined with multi-source monitoring techniques,including stress–strain,digital image correlation(DIC),acoustic emission(AE),microseismic(MS),parallel electric(PE),and electromagnetic radiation(EMR),the mechanical behavior and multi-source information responses were comprehensively analyzed.The results show that the peak stress and displacement of the models are positively correlated with the support strength.The multi-source information exhibits distinct response characteristics under different supports.The response frequency,energy,and fluctuationsof AE,MS,and EMR signals,along with the apparent resistivity(AR)high-resistivity zone,follow the trend U-1>T-2>4D-R-3.Furthermore,multi-source information exhibits significantdifferences in sensitivity across different phases.The AE,MS,and EMR signals exhibit active responses to rock mass activity at each phase.However,AR signals are only sensitive to the fracture propagation during the plastic yield and failure phases.In summary,the 4D support significantlyenhances the bearing capacity and plastic deformation of the models,while substantially reducing the frequency,energy,and fluctuationsof multi-source signals.

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Enterprise application integration encounters substantial hurdles,particularly in intricate contexts that require elevated scalability and speed.Transactional applications directly accessed by many systems frequently overload databases,undermining process efficiency.This paper examines the utilization of data lakes-historically used for data analysis-as a centralized integration layer that accommodates various temporalities and consumption modalities.The sug-gested method diminishes system interdependence and the burden on transac-tional databases,enhancing scalability and data governance in both mono-lithic and distributed frameworks.
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.
文摘As a renowned historical and cultural city,Luoyang boasts a wealth of tourism resources,including sports venues,natural landscapes,and cultural heritage sites,laying a solid foundation for the integrated development of the tourism industry and sports events in recent years,with remarkable achievements in practice.However,from the perspective of sports-tourism integration,Luoyang’s event tourism still faces a prominent issue of uneven development:a surge in tourists during peak seasons,leading to overcrowded attractions,and a scarcity of visitors during off-peak seasons,resulting in idle resources.This not only leads to inefficient resource utilization but also restricts the enhancement of economic benefits and hinders sustainable development.In light of this,this paper comprehensively employs literature research,case analysis,and fieldwork methods to systematically analyze the current development status of event tourism in Luoyang within the context of sports-tourism integration.The aim is to provide theoretical and practical support for achieving high-quality and balanced development of local event tourism,offering valuable references for addressing the issue of uneven development and moving towards a sustainable future.
