Finger Scanning Experiments: Participants conducted experiments while seated and wearing an eye mask to eliminate visual information. They were instructed to horizontally scan the surface back-and-forth eight times with one of their fingers to assess surface roughness. The finger's motion was optically captured at a frame rate of 60 fps. Scanning speed was determined by measuring finger positions at each frame and dividing them by the frame length. Image analysis was performed using OpenCV, where the finger outline was extracted from the video.

The Excel file contains samples of a laboratory-generated noisy voltage signal with a dc component under nonideal sampling.

This test signal is generated in a laboratory for assessing power frequency estimation algorithms.

The first column represents the sample time.

The second column represents the voltage signal samples.

The reference fundamental frequency is 46 Hz.

The nominal voltage amplitude is 10 V.

The actual sampling rate varies in the range of 9.99834~10.01027 kHz.

We present an Arabic Twitter dataset for online extremism detection consisting of 89K tweets with associated metadata. The dataset was manually annotated by three experts and achieved a Gwet’s AC1 score of 0.6, indicating substantial inter-annotator agreement. We performed further analysis of the tweet metadata to identify important features. For the extremism dataset, there were 89,816 tweets in total published by 52,929 unique users.
