Large-scale geodetic data acquisition is fundamental to infrastructure lifecycle management,construction quality control,urban digital twins,and hazard monitoring,yet conventional surveying workflows remain labor-intensive and difficult to scale in complex or hazardous environments.The industrial robot technology is proving to be an enabling technology in providing repeatable,high-throughput,and safety-conscious geodetic acquisition through its ability to offer controllable motion,stable sensor deployment,and autonomy coupled with perception stacks.The review itself is a synthesis of the recent studies on robot-based geodetic acquisition from the platform workflow application perspective.We summarize in the priority industrial robot platforms which have potential applications in geodesy,distinction being made between those based on autonomous mobile robots,mobile manipulators,fixed-base manipulators,cooperative multi-robot arrangements,and the design considerations underlying their construction:geometric stability,payload loading,and tightly constrained safety of operation.We then consider sensing configurations,principles of calibration and synchronization,as well as acquisition strategies that regulate the completeness of data and measurement consistency.The foundations of core processing are examined in light of georeferencing,registration,Simultaneous Localization and Mapping(SLAM)-based localization,and uncertainty propagation,which are essential to achieve survey-grade outputs.The evidence of application is discussed in the framework of infrastructure monitoring,construction,industrial facilities,urban/corridor mapping,mining,and indoor/underground settings,showing areas of obvious robotics advantage in repeatability and risk mitigation,as well as conditions of limitation because of the Global Navigation Satellite System(GNSS)denial,drift,calibration sensitivity,and inconsistent evaluation practices.Lastly,we determine research priorities such as benchmark datasets and metrics,accuracy-motivated autonomy,strong multisensor fusion with uncertainty results,and a closer association with Building Information Modeling(BIM)/digital twin pipelines. 展开更多

Background:Magnetic resonance imaging(MRI)is of considerable importance due to its wide range of applications in both scientific research and clinical diagnostics.Acquiring high-quality MRI data is of paramount importance.Super-resolution reconstruction serves as a post-acquisition method capable of improving MRI data quality.Current methods predominantly utilize convolutional neural networks in super-resolution reconstruction.However,convolutional layers have inherent limitations in capturing extensive spatial dependencies due to their localized nature.Methods:We developed a new methodology that enables rapid and high-quality MRI data acquisition through a novel super-resolution approach.We proposed an innovative architecture using transformers to exploit long-range spatial dependencies present in images,allowing for an unsupervised learning framework specifically designed for super-resolution tasks tailored to individual subject.We validated our approach using both simulated data and clinical data comprising 40 scans acquired with a 3-T MRI system.Results:We obtained images with T2 contrast at an isotropic spatial resolution of 500μm in just 4 min of imaging time,and simultaneously,the signal-to-noise ratio and contrast-to-noise ratio were improved by 13.23% and 18.45%,respectively,in comparison to current leading super-resolution techniques.Conclusions:The results demonstrated that incorporating long-range spatial dependencies substantially improved super-resolution reconstruction,thereby allowing for the acquisition of high-quality MRI data with reduced imaging time. 展开更多

A state-of-the-art detector array with a digital data acquisition system has been developed for charged-particle decay studies,includingβ-delayed protons,αdecay,and direct proton emissions from exotic proton-rich nuclei.The digital data acquisition system enables precise synchronization and processing of complex signals from various detectors,such as plastic scintillators,silicon detectors,and germaniumγdetectors.The system's performance was evaluated using theβdecay of^(32)Ar and its neighboring nuclei,produced via projectile fragmentation at the first Radioactive Ion Beam Line in Lanzhou(RIBLL1).Key measurements,including the half-life,charged-particle spectrum,andγ-ray spectrum,were obtained and compared with previous results for validation.Using the implantation–decay method,the isotopes of interest were implanted into two doublesided silicon strip detectors,where their subsequent decays were measured and correlated with preceding implantations using both position and time information.This detection system has potential for further applications,including the study ofβ-delayed charged-particle decay and direct proton emissions from even more exotic proton-rich nuclei. 展开更多

As the key ion source component of nuclear fusion auxiliary heating devices, the radio frequency (RF) ion source is developed and applied gradually to offer a source plasma with the advantages of ease of control and high reliability. In addition, it easily achieves long-pulse steady-state operation. During the process of the development and testing of the RF ion source, a lot of original experimental data will be generated. Therefore, it is necessary to develop a stable and reliable computer data acquisition and processing application system for realizing the functions of data acquisition, storage, access, and real-time monitoring. In this paper, the development of a data acquisition and processing application system for the RF ion source is presented. The hardware platform is based on the PXI system and the software is programmed on the LabVIEW development environment. The key technologies that are used for the implementation of this software programming mainly include the long-pulse data acquisition technology, multi- threading processing technology, transmission control communication protocol, and the Lempel-Ziv-Oberhumer data compression algorithm. Now, this design has been tested and applied on the RF ion source. The test results show that it can work reliably and steadily. With the help of this design, the stable plasma discharge data of the RF ion source are collected, stored, accessed, and monitored in real-time. It is shown that it has a very practical application significance for the RF experiments. 展开更多

Neutral beam injection (NBI) heating is one of the most efficient auxiliary plasma heating methods for fusion devices. The data acquisition control system (DACS) with PXI (pe- ripheral component interconnect extensions for instrumentation) data acquisition card for the first NBI system in the experimental advanced superconducting tokamak (EAST) is presented in this paper. As an important sub-system, DACS is designed to obtain physical measurement signals in the EAST NBI system and to deal and store these data with the Lempel-Ziv-Oberhumer (LZO) lossless data compression algorithm, as well as offer convenient data call-back and access inter- faces to the user for examining and analyzing the data. Experimental results show that accurate data will ensure that researchers correctly analyze it and then properly adjust the experimental parameters or operation, so DACS should take a large step in improving experimental efficiency. Tile hardware and software sections are briefly presented in this paper, and now this system has been tested to be able to work reliably and steadily. 展开更多

A newly developed digital data acquisition system,which is based on the digital pulse processor Pixie-16 modules by XIA LLC,was tested with the c-ray detector array of the China Institute of Atomic Energy using the cray source and in-beam c-rays.A comparison between this digital data acquisition system and the conventional analog data acquisition system was made.At a low count rate,both systems exhibit good and comparable energy resolutions.At a high count rate above 8.8 k/s,while the energy resolution obtained by the analog system deteriorates significantly,the energy resolution obtained by the digital system is nearly unchanged.Meanwhile,experimental data with higher statistics can be collected by the digital system.The advantage of this digital system over the conventional analog system can be ascribed to its excellent capability of handling pile-up pulses at higher count rates,and the fact that it has nearly no dead time in data transmission and conversion. 展开更多
