title: Transient Convective Flow with Viscous Dissipation in a Horizontal Channel: MATLAB Implementation

description: This dataset contains a complete MATLAB implementation for simulating transient convective flow with viscous dissipation in a horizontal channel filled with water. The code models the time-dependent development of combined Couette-Poiseuille flow between two parallel plates under the influence of a pressure gradient, wall motion, and differential heating.

The physical model accounts for key phenomena: momentum transfer through viscous stresses, heat conduction, convective energy transport, and internal heat generation due to viscous dissipation (Joule heating). The Boussinesq approximation is employed to include buoyancy effects on pressure distribution. The numerical approach utilizes a Fourier series expansion to solve the unsteady momentum equation analytically, while the energy equation is solved via spectral projection to capture the temperature field evolution.

All thermophysical properties correspond to water at 20°C. The simulation parameters are configured to ensure laminar flow conditions (Re &lt; 2000). The main script calculates velocity, temperature, pressure, shear stress, and dissipation function profiles at multiple time instances, visualizing the transition from initial to steady state.

Primary outputs include a comprehensive six-panel figure summarizing the flow's hydrodynamic and thermal development, plus console output of key dimensionless numbers (Reynolds, Prandtl, Grashof) and characteristic time scales. This code is designed for research and educational purposes in computational fluid dynamics, heat transfer, and applied mathematics, providing a transparent tool for studying non-isothermal viscous flow transients.

The dataset consists of the main MATLAB script and a detailed README file.

title: Indicators of urban competitive vulnerability in Spanish tourist cities (2014–2024)

description: This dataset provides a harmonised panel of economic, social and tourism performance indicators for six major tourist cities in Spain—Barcelona, Madrid, Palma de Mallorca, Seville, Málaga and Valencia—covering the period from 2014 to 2024. The data have been compiled from official statistical sources and systematically organised to support empirical analyses of urban dynamics, competitiveness and vulnerability in tourism-oriented cities.

The variables capture key dimensions of urban performance, including economic activity, labour market conditions, social and demographic characteristics, tourism intensity and accommodation capacity. Together, these indicators allow for a multidimensional assessment of how tourism development interacts with broader socio-economic structures at the urban level over time.

The dataset is designed to facilitate comparative and longitudinal analyses, enabling researchers to explore trends, disparities and structural changes across cities and periods. It is particularly suitable for studies on urban competitiveness, vulnerability, resilience and sustainable tourism development, as well as for quantitative modelling and policy-oriented research. The data underpin the empirical analysis presented in the associated research article titled “Urban competitive vulnerability in tourist cities: An integrated framework and empirical evidence from Spain”.

title: RoseVisuals - Multi-class Dutch Rose Petal Dataset From Controlled Environment.

description: The RoseVisuals - Multi-class Dutch rose petal dataset represents an extensive advancement in flower image repositories by offering a meticulously curated collection of 1,995 high-resolution, labeled images that capture the significant diversity of Dutch rose petals, encompassing a wide spectrum of color varieties and health conditions. Unlike other datasets that tend to primarily focus on broad plant disease detection or generic flower classification, often neglecting the importantance of petal-level features -RoseVisuals addresses this critical gap and offers a broader view, capturing a wide range of petal colors and their health conditions. The dataset comprises images of petals in shades like red, yellow, pink, purple, white, orange, plus stunning bi-color and multi-color varieties. On top of that, it sorts them by health—whether they’re fresh, dry, or diseased. 
In total, RoseVisuals zip folder includes 1,995 images in jpg format. Breaking it down by color, there are 244 Bi-color, 116 Multi-color, 211 Orange, 239 Pink, 237 Purple, 230 Red, 214 White, 239 Yellow. As for health, 828 are Fresh petals, 902 are Dry petals, and 265 are Diseased petals. All images in the RoseVisuals dataset were captured under controlled lighting conditions and using the Samsung S21 Ultra’s pro camera mode, ensuring uniformity and clarity. The built-in device flash was used for all images to minimize shadows and enhance detail, and every image was taken at a consistent resolution of 3000×4000 pixels with portrait frame. Each image has been pre-processed with a unique ID—like "FRESH_RED_001," where "FRESH" shows the petal’s condition, "RED" is the color, and "001" is a three-digit identifier to keep everything organized. This rich annotation assists deep learning researchers to explore fine-grained visual cues related to petal health, color variation, and disease manifestation. This dataset is perfect for training machine learning models, especially for quality checks or projects tied to agriculture, perfumes, edible products, flavors, or even cosmetics. It’s a treasure trove for anyone looking to explore the world of Dutch roses!

title: An EEG-ECG Dataset of Stress and Mental Workload during Cognitive Tasks

description: A modified version of the Montreal Imaging Stress Task (MIST) was employed to investigate stress-induced neural and physiological changes. The task was adapted to suit the experimental protocol and consisted of computer-based arithmetic problems presented under two conditions: a neutral baseline and a stress-inducing condition. A within-subject design was used, with each participant completing both conditions in separate sessions spaced two weeks apart to minimize carryover effects. Each session consisted of seven stages: task familiarization, an eyes-open resting baseline, four arithmetic task levels (AC1–AC4) of increasing difficulty, and a post-task recovery period.

In the neutral condition, the task was designed to assess cognitive workload without inducing stress. After a non-recorded training phase, EEG and ECG signals were recorded during a 5-minute eyes-open baseline while participants fixated on a dot. Participants then completed four arithmetic levels: single-digit addition and subtraction (AC1), small-scale multiplication (AC2), multi-operand expressions (AC3), and expressions including division (AC4). Immediate correctness feedback was provided after each response, with no time constraints or performance pressure. A 5-minute recovery period followed the final task.

The stress condition followed the same structure but incorporated psychosocial stressors, including response time limits, visible countdown indicators, accuracy manipulation to maintain performance below 50%, and evaluative feedback such as “time out” messages. Performance scores were displayed after each task block to increase performance pressure and induce stress.

ECG signals were recorded using bipolar limb leads (Lead I and Lead II) and amplified using an ECG acquisition system. Data were sampled at 1,000 Hz and bandpass filtered between 0.3 and 200 Hz. EEG data were recorded from eight scalp electrodes (Fp1, Fp2, F3, F4, P3, P4, T3, and T4) following the international 10–20 system, referenced to bilateral mastoids. Signals were acquired using an EEG amplifier at a sampling rate of 2,000 Hz, with electrode impedances maintained below 10 kΩ.

ECG signals were further high-pass filtered at 1 Hz and inspected for cardiac abnormalities. EEG preprocessing was conducted using dedicated analysis software, applying a 1 Hz high-pass filter and a 50 Hz notch filter. Artifact rejection excluded segments exceeding ±150 µV, eye-blink artifacts were manually removed based on frontal channels, and clean 2-second EEG segments were extracted for subsequent analysis.

title: MDPM

description: We characterize the hydrological processes of a mountainous highway and its surrounding area under heavy rainfall using three arguments: surface runoff, groundwater, and solid matter. The study area is modeled as a network, abstracted into 4,706 nodes. The dataset comprises 47,060,001 rows and 10 columns. Column-wise, the first three columns correspond to the three arguments; columns 4 to 9 represent static data, including elevation, slope, NDVI, LAI, a slope-adjusted Curve Number (CN) value, and soil shear strength. The 10th column records rainfall intensity. Row-wise, the first row contains headers, and each subsequent block of 4,706 rows represents one iteration. With 10,000 iterations in total and a time interval of 1.5 seconds per iteration, the simulation covers approximately 4 hours of the rainfall process.
