In the ongoing evolution of OceanBase database system, it is essential to enhance its adaptability small-scale enterprises. The system has demonstrated stability and effectiveness within Ant Group other commercial organizations, besides through TPC-C TPC-H tests. this paper, we have designed a stand-alone distributed integrated architecture named Paetica address overhead caused by components in mode, with respect system. enables adaptive configuration that allows support both serial parallel...
For quadrotor unmanned air vehicles (UAVs) flight control problem, a robust controller design approach is presented.The consists of two parts: an inner-loop attitude and outer-loop position controller.The designed with based on signal compensation.The realized classical PD method.It applied to UAV developed in our laboratory realize indoor hovering.Experimental results demonstrate the effectiveness this approach.
The application of the Internet Things is increasing in momentum as advances artificial intelligence exponentially increase its integration. This has caused continuous shifts paradigm with levels complexity. Consequently, researchers, practitioners, and governments continue facing evolving challenges, making it more difficult to adapt. especially true education sector, which focus this article. overall purpose study explore IoT and, specifically, learning. Our methodology follows four...
Flight performances of unmanned helicopters can be affected by wind gusts especially when they are carrying out aggressive mission. In this study, robust position control problem under manoeuvres is investigated in the presence time‐varying disturbances for a lab helicopter. A controller designed two steps: first, nominal static linear feedback applied to obtain desired tracking system; then, compensator introduced restrain influences parameter uncertainties, non‐linear uncertainties and...
The review summarizes the results of Russian-Chinese expert seminar “Development Science Diplomacy in Arctic under Global Challenges”, which was organized December 2023 Arkhangelsk, Russia. aim is described: accumulation intellectual resources universities and scientific institutes Russia China. need to unite potential two countries determined by current geopolitical context, development relevant functional solutions international humanitarian issues becomes extremely important. Northern...
In this study, we present a strategic change theoretical model and empirically validate it in the context of inter-governmental organizations. We followed survey methodology approach tested our hypotheses using exploratory confirmatory factor analysis. Traditional management models were created primarily with private sector mind. Therefore, validation constructs for their appropriateness to construct is essential, especially that these types organizations, such as those United Nations...
For the security issue in cloud storage systems, we design a system (for short CSSS). Firstly, The CSSS integrates information isolation, accessing control, virus detection, metadata safeguard of crucial data and fast-speed retrieval; Secondly, with help connect control interface, authorized users can safely access CSSS. This provide solid foundation for protection multilevel private enterprise cloud. result on trial displays that this ensure system, few side effects I/O performance network
In order to obtain the air spring characteristics, static and dynamic experiments have been implemented firstly. The stiffness with displacement excitation frequency computed from measured data. experimental results show that hysteresis in one displacement-force cycle becomes better when of harmonic signal increases, but it does not change too much as is higher than 1Hz. And goes up increasing initial pressure frequency. then, based on research, mathematical model constructed light energy...
The deployment of high-altitude vehicles in near space with the purpose providing Internet, communication, and other services represents new frontier aerospace activities. Near-space operations are attracting growing interest due to their mult-purpose nature anticipated high profitability. Despite such positive perceptions, near-space plans are, however, hampered by uncertain international legal status space. Using precedent exclusive economic zone (EEZ), this article suggests a...
In a relatively short period of time, the Trump administration has been fairly active in field space. The reconstitution National Space Council, under direction Vice President Pence, President's signing Policy Directive 1, that calls for return humans to Moon, and announcement Strategy an 'America first' approach space, have highlights this process. A key component administration's promotion commercial (private) space activities through effort regulatory reform intended facilitate free...
Abstract A two‐step process involving, the pre‐metallization of SiC ceramic by Ag‐Cu‐Ti foil and Al based filler alloy was developed to join 2219 aluminum metallized SiC. The composition layer investigated. effect metallization temperature on microstructure mechanical properties joint analyzed. brazing showed that from substrate reacted with form intermetallic compounds. 3 Ti, 2 Ag Cu were detected in joint. Ti 5 Si , TiC compounds found adjacent reaction With increasing temperature, shear...
