This dataset abstract presents findings from a study focused on enhancing surface crack detection in railroad safety through the development and optimization of a hybrid Eddy Current Testing (ECT) probe. Traditional ECT methods often encounter challenges related to 'lift-off noise', which arises from variations in probe-to-material distances. To mitigate this issue, the study introduces a novel probe design that integrates transmit and differential receiver coils, aimed at improving detection sensitivity and minimizing lift-off impact.

Dataset used to extract channel model parameters such as delay and Doppler from satellite passes. It has 100 user spread on Earth, and per user it is simulated 10 minutes of Starlink satellites passes, The information stored is the UE position, and the satellite speed and position in ECEF coordinates with 1 second of temporal resolution. It can be used to generate Doppler/delay curves to apply to a wireless channel model.

This dataset was obtained from the ionogram at Kupang in 2022 to investigate the frequency window of the Near Vertical Incidence Skywave (NVIS) channel with homogenous Time of Flight (ToF) values. All data is in the form of.mat files (MATLAB). The first dataset is in Matlab variables ('DataWidthFrekHourly','DataCenterWidthFrekHourly'), which consist of maximum window frequency values with homogenous ToF and the center frequency of the widest window. The structure of the data array is 96x365, with the row as the time (1:96) and the column as the day in one year (1:365).

This dataset contains LTE access signals (PRACH) emitted by 7 mobile phones and 1 USRP B205 software defined radio platform equipment. Files are stored in MAT form that can be read by MATLAB. The dataset of the mobile phone includes data from 3 different locations (\dif_loc), 3 different test times (\dif_date), and 3 different power-on times (\dif_working). The software defined radio platform equipment dataset consists of 3 datasets at different locations and 3 different test times.

To improve the comprehensive monitoring and early warning capabilities for typhoons, heavy rain, sea fog, and other severe weather in the SCS region, the China Meteorological Administration has established a variety of observation stations, including automatic weather stations (AWS), buoy stations (BS), radiosondes, and weather radars in the SCS region. The surface bulk measurements from April 2019 to November 2021 used in Hainan were collected by 5 Buoys.

This dataset contains RF (Radio Frequency) signals obtained from simulations, which model ultrasound propagation in cortical bone.
The simulations were designed to provide insights into the behaviour of ultrasound waves in cortical bone tissues, both in intact and pathological conditions. The dataset covers a wide range of parameters, including varying thickness (1-8 mm), porosity (1-20%), and frequency (1-8 MHz), allowing to explore the impact of these factors on ultrasound signal characteristics.

To test the feasibility of the idea: Using the processed data of sentinel-2 and GlobeLand30 as the input image and ground truth of subspace clustering for land cover classification, a dataset named 'MSI_Gwadar' is created.
'MSI_Gwadar' is a multi-spectral remote sensing image of Gwadar (town and seaport, southwestern Pakistan) and its four regions of interest, which includes MATLAB data files and ground truth files of the study area and its four regions of interest.

This is the dataset of the paper: A Non-Invasive Circuit Breaker Arc Duration Measurement Method with Improved Robustness Based on Vibration–Sound Fusion and Convolutional Neural Network (https://doi.org/10.3390/en16186551). Here is the abstract of the paper. Previous studies have shown that the contact wear estimation of circuit breakers can be based on the accumulative arc duration. However, one problem that remains unresolved is how to reliably measure the arc duration.

We employed Hexacopter unmanned aerial vehicle (UAV) equipped with the SPECIM FX17E hyperspectral camera to implement ultra-low-altitude flight aerial photography missions with atmospheric correction processing. We collected three hyperspectral images and combined them into three data pairs, which exhibit varying degrees of spectral shift. Among them, a hyperspectral image including six types of ground objects was collected in Changsha at 4:00 pm on September 27, 2021, with sunny weather and a flight altitude of 30m, named CSSunny.

Manual palpation of organs played a vital role in detecting abnormalities in open surgeries. However, surgeons
have lost this ability with the development of minimally invasive surgeries. This challenge led to the development of artificial sensors for palpating the patient's organs and tissue. The majority of research done is related to improving the measurement of tissue compliance by the development of versatile force sensors for surgical
