Trajectory prediction is a prerequisite for missile and high-speed vehicle guidance interception.To address the trajectory problem for the near space hyper-sonic unpowered gliding vehicle.Firstly,the trajectory prediction mechanism is analyzed.Based on th
With the expansion of data scale and the increase in data complexity,it is particularly important to accurately identify clusters and efficiently save clustering results.To address this,we propose a novel clustering algorithm,Shape clustering based on dat
Electromagnetic emissions from electrical information equipment may contain useful information and lead to information leakage. In order to detect the electromagnetic information leakage of digital vi
Vehicular ad hoe networks (VANETs) cre-ate an vital platform for communication between vehicles,which can realize accident warning,auxiliary driving,road traffic information query,passenger communication and other applications.While providing convenient s
An Asynchronous Quasi-Cloud/Edge/Client Collaborative Federated Learning Mechanism for Fault Diagnos
Although the federated learning method has the ability to balance data and protect data privacy by means of model aggregation,while the existing methods are difficult to achieve the effectiveness of centralized learning under data sharing.The existing fed
Ultrasound computed tomography(UCT)is a promising approach for early breast cancer screening.However, current studies which use prone posture to collect breast ultrasonic data cause four problems, a l
Ionizing radiation effect and failure mechanism of Digital signal processor (DSP) is studied through test-board and automatic test equipment to find the relationship between system function failure and parameter degradation.Static bias is more sensitive t
This paper aims to solve the problem of low efficiency,high cost and instability in opportunistic network transmission in the process of mobile group intelligence perception task allocation.Two multi-task dynamic distribution methods based on Lowest cost
A four-stage Operational transconduc-tance amplifier (OTA) used in an infrared temperature sensor adopting the proposed Feed-forward Gm-stage and segmenting nested Miller compensation technique is presented.The purpose of the proposed segment compensation
Online Video Popularity Regression Prediction Model with Multichannel Dynamic Scheduling Based on Us
Popularity prediction of online video is widely used in many different scenarios.It can not only help video service providers to schedule video web sites,but also bring considerable profits on investment for both providers and advertisers if popularity of
