An access scheme based on the random access occasion dynamic allocation by Shaoxiong JING, Yue YUAN, Jiawei XIONG, Junxuan WANG

“…With the rapid development of the internet of things (IoT), the application of machine type communication (MTC) in life has grown substantially, and the deployment of machine type devices (MTD) has become more and more intensive.In this case, if there is an unexpected situation such as a power outage and a network failure, a large-scale MTD will initiate access to the base station at the same time when the device is powered on.When the device accesses the base station, it needs to complete the downlink synchronization, system message receiving, random access (RA) and other processes.However, the preamble resources that can be allocated by the base station are limited and cannot meet such a huge access demand, which causes network congestion and affects the access probability and access delay of the device.In order to alleviate the access conflict of RA, a dynamic random access occasion (RO) adjustment scheme was proposed based on the uplink and downlink subframes and physical random access channel (PRACH) configuration, and time-based part of the MTD with high delay requirements allocates specific preamble resources.The simulation results show that this scheme can effectively improve the throughput of the system and reduce the access delay of the device.…”

VALVE FUZZY RELIABILITY EVALUATION METHOD BASED ON THE INFLUENCE OF NON-CRITICAL STATE OF THE SYSTEM by YU ShuRong, LUO WeiYe, XUE RuiYuan, YIN SiMin, LI YongLin

“…At present,the reliability of a single indicator is evaluated by a conventional reliability model.The results have only two states:the system is completely normal and the system is completely faulty.It is difficult to determine what state the valve system is between "good" and "failed".At the same time,ignoring the impact of non-critical state of the system on system reliability and evaluating method with a single indicator will result in insufficient evaluation results.Therefore,a fuzzy evaluation method based on triple index was proposed.The valve system failure probability PF,the failure probability considering the influence of non-critical states of the system P_EF and the mean time between failures MTBF as the indicators to evaluate the reliability gray number clustering were considered.The failure probability considering the influence of the non-critical state of the system was obtained by the cumulative failure probability of the system and the number of expected state transitions.The experimental results indicated that the method can well describe the influence of the non-critical state of the system on the reliability and can determine the reliable level of the system.…”

Synchronous collaborative application of nuclear power engineering design platform by Zhihua ZENG, Delong YI, Yan LI

“…At present,the nuclear power business shows the development trend of multi-route,multi-base develop-ment trend.Coupled with the huge workload of nuclear power engineering design and the fine division of labor cha-racteristics,the relevant professional in different places appears more and more cross-design in the nuclear power en-gineering design,resulting in the frequency of funding becoming more and more dense between the various profes-sional.How to shorten the synchronization time of engineering design data between different places,and even achieve real-time synchronization of engineering design data is worth to study in the field of collaborative design of nuclear power projects.From the point of view of system verification,the existing popular virtualization technology was used to carry out an in-depth exploration and verification on the synergetic synergy of nuclear power engineering design,and a set of auxiliary access platform was added on the basis of the original design platform structure to real-ize remote user access and collaborative design of nuclear power projects.The research results have guiding signific-ance for the follow-up design and production platform upgrade and optimization.…”

Les insectes vivants dans l’espace anthropisé. Incarnations de la dichotomie nature/culture en architecture by Delphine Lewandowski

“…Living insects are part of an unthought field of nature in architecture, as they are often considered undesirable, but also because of scale, space, and time issues. The dichotomies that are associated with them: “desirable/undesirable”, “controlled/uncontrolled”, or “fascination/repulsion”, illustrate the impact that naturalism has on contemporary architectural culture and its production, at a time when the integration of the living in the built environment is increasingly desired and standardized. …”

Design and implementation of AI-based all-scenario intelligent base station power-saving system by Wei ZHAO, Bei LI, Ning MENG, Tingwei WANG, Junfan LIN, Le CHEN, Yuhua HU, Hanyuan YANG

“…In the context of intensive network construction, how to realize automatic, intelligent, and experienceguaranteed base station energy consumption management has become a pain point for current operators in operation management.A 3G/4G/5G smart base station power saving solution with full intelligent detection, full-scenario modeling, and full-process self-service was innovatively proposed.The coverage scene was distinguished by a dynamic time warping algorithm, and the SARIMA model was used to predict the time frame to build the model dynamically.Monitoring indicators ensured quality of experience, automatically issue power-saving strategies, and promptly raise SMS alerts.In the case that the user had no perception, the energy consumption of the base station was saved to the greatest extent at the cell granularity level.This method had been implemented on a pilot study in a province.The average annual power saving efficiency of a single station in the pilot area can reach 9.24% per day per station, which can be put in actual production.…”
