A table by Sayed Naseel Mohamed Thangal containing input parameters, optimized parameters, and results for a biomechanical swing task. The dataset includes a 'Source' column indicating whether values were calculated from scaling literature or found through optimization, and 'Coefficient' and 'Exponent' columns for power law equations quantifying size effects. It was last updated on April 21, 2026.
An extract from the gear database of the Salesian Polytechnic University (UPS) used in a research article on early fault detection. The data includes measurements from a gearbox in good condition (Phase I) and with low and high severity failures (Phase II). The dataset was published by Antonio Pérez-Torres on figshare in May 2026 and includes an experimental plan and R code for processing.

794 pilots were surveyed in an observational study investigating the prevalence and factors of Dry Eye Syndrome (DES). All surveyed pilots were affected, with 88.40% experiencing moderate DES and 11.60% severe DES. The dataset, authored by Mingyue Zhang and last updated in March 2026, contains results analyzed via multiple linear regression.
Ordnance Survey provides postcode data for the United Kingdom in both point and polygon geometries. The postcode information is sourced from Royal Mail, while polygon geometry is calculated using address data from Local Authority Land and Property Gazetteers. This dataset is used for service delivery and statistical analysis.
A dataset from a run-to-failure tension-tension fatigue experiment measuring damage evolution in CFRP cross-ply laminates. The data was collected by the National Aeronautics and Space Administration (NASA) and last updated in March 2026. It supports a proposed framework for estimating fatigue damage propagation by connecting micro-scale and macro-scale models within a Bayesian filtering approach.
Fisheries and Oceans Canada produced annual and composite maps of lobster landings, trap hauls, and catch per unit effort (CPUE) on a statistical grid for the Maritimes Region from 2015 to 2019. The analysis includes Bay of Fundy Disputed Zone data reported at the coordinate level and standardizes series by grid area. This data is intended for spatial planning and management applications, addressing a gap in region-wide coordinate-level commercial logbook data.
Aishwa Roy's dataset contains Pearson correlation coefficients and p-values analyzing relationships between germination and yield parameters from a low EC soil experiment. The 32.5 KB ZIP archive includes tabular data, R code for statistical analysis, and explanatory documents. It was last updated on April 7, 2026.
