The sixth-generation (6G) communication requires supporting massive Internet of Things (IoT) devices and extremely differentiated IoT applications for the air–space–ground integrated network. Relying on aerial superiority, unmanned vehicle (UAV) is capable acting as an base station (BS) deployment in remote disaster areas. A UAV-supported clustered nonorthogonal multiple access (C-NOMA) system put forward this article. Specifically, UAV provides services to terminals BS based...
The aerial platform based wide-area Internet of Things (WAIoT) can effectively settle wireless information interactions in emergency scenarios. However, it confronts lots unprecedented service requirements and technical challenges. To solve these issues, this article establishes an unmanned vehicle (UAV)-based WAIoT deployment framework by considering three typical scenarios including power outage, massive user connections, island relief. Serving as base station or mobile relay, the UAV...
Abstract. Quantitative measurements of atmospheric total OH reactivity (kOH′) provide crucial insights into photochemistry. However, widespread application is challenging due to insufficient equipment and the complexity existing instrumentation. In this work, we report development a portable laser-flash photolysis Faraday rotation spectroscopy (LP-FRS) instrument for real-time in situ measurement kOH′. To achieve efficient overlapping between pump probe laser realize long effective...
Abstract. Quantitative measurements of atmospheric total OH reactivity (kOH') provide crucial insights into photochemistry. However, widespread application is challenging due to insufficient equipment and the complexity existing instrumentation. In this work, we report development a portable laser-flash photolysis Faraday rotation spectroscopy (LP-FRS) instrument for real-time in-situ measurement kOH'. To achieve efficient overlapping between pump probe laser realize long effective...
Unmanned aerial vehicles (UAVs) are able to act as movable base stations enhance wireless coverage for edge users with poor ground communication quality. However, in urban environments, the link between UAVs and can be blocked by obstacles, especially when complicated terrestrial infrastructures increase probability of non-line-of-sight (NLoS) links. In this paper, order improve average throughput, we propose a multi-UAV multicast system, where multi-agent reinforcement learning method is...

The application potential of thermal radiation measurements in energy harvesting, infrared stealth, and radiative cooling has stimulated renewed research interest this domain. However, the precise measurement laboratory settings encounters challenges stemming from emission by optical components surrounding environment. In study, a method was devised to segregate backgrounds sample signal, thereby facilitating accurate spectral emissivity samples at room temperature higher. Calibration...
As an essential part of modern intelligent decision-making science, multi-attribute problems can effectively select and rank all candidate schemes under multiple indicators. Because the complexity real environment uncertainty problem, interval numbers are often used to represent evaluation information object. The existing methods rarely use object set but give decision results by selection or ranking, which have strong subjectivity. We propose a ranking method from acceleration viewpoint...
How to improve the spectrum utilization efficiency support difference services in specific frequency band is becoming more and critical issue considering limited resource, sharing only way out. The traditional approach on usage among different industries especially between satellite terrestrial industry need be changed from competition toward convergence. With fast development of communication network, it will play an important role B5G 6G network evolution. In this paper, expanded new...
The application scope of UAV in the power field is gradually expanding, which puts forward higher requirements for accurate landing UAV. At this stage, fixed-point mainly depends on RTK, but RTK easy to be disturbed by external environment, so it can not meet fine landing. This paper proposes an improved yolov4-tiny algorithm, adds convolutional attention module network structure feature pyramid reduce interference complex backgrounds target recognition. In system, guided fly above nest...
