title: Thermal Inspection Dataset for Defect Segmentation in CFRP Laminates

description: This dataset contains thermal image data and corresponding annotations from a pulsed thermography (PT) inspection conducted on a carbon fiber-reinforced polymer (CFRP) laminate. The dataset is designed to support research in defect segmentation, early defect detection, and related applications in composite material inspections.

Dataset Composition:

Images:
A total of 1,034 thermal images captured using a midwave infrared (MWIR) camera at a resolution of 640 × 512 pixels and a frame rate of 55 Hz. These images were recorded during PT inspections following a short, intense heat pulse.

Annotations:
Each of the thermal images has a corresponding expert-annotated image, resulting in 1,034 segmentation masks. The annotations were created using the VGG Image Annotator, a tool developed by the Visual Geometry Group at the University of Oxford, and represent the ground truth data for model training and validation.

Sample Details:

Material:
The sample is a unidirectional carbon/PEEK laminate with a fiber volume fraction of 61%. The stacking lay-up of the laminate is [02/902]6, and its dimensions are 100 × 100 mm.

Defect Characteristics:
Artificial defects in the form of Kapton tape inserts were introduced into the laminate during the moulding process. These defects vary in size and depth:

Nominal Depths:
D1: 0.13 mm
D2: 0.26 mm
D3: 0.39 mm
Nominal Sizes:
2 × 2 mm
3 × 3 mm
4 × 4 mm

Inspection Methodology:
A MWIR camera captured thermal profiles as the surface of the laminate cooled after heat application. Images display the temporal evolution of surface defects, highlighting changes over time. This temporal variation is critical for identifying and segmenting defects accurately.

Applications:
Defect segmentation in composite materials.
Development and validation of machine learning models for thermal image analysis.
Early detection and tracking of defect progression.

Ground Truth and Segmentation Masks:
The annotated dataset includes:
Segmentation masks created from the annotations, used for model training and validation.

title: Survey data to validate a model for assessing food fraud intentions

description: The data was collected primarily to validate a mathematical/psychometric model used to assess the food fraud intentions of respondents or subjects, S. The data was collected using an online survey tool between November 2021 and February 2022. The total number of participants was 54. 

The respondents were selected from the Zimbabwe food manufacturing industry and academics. The demographic questions collected data about respondent's age, sex, work experience, location, industry, and work position. 

The survey contains 39 questions or items which gather reactions and opinions regarding activities that may or may not lead to food fraud. All the questions have a dichotomous scale with YES/NO or GOOD/BAD options. The options were coded as follows 1-YES/GOOD and 0-NO/BAD. The questions were divided into two categories, group 1 was related to malicious intent (\Pi) and group 2 to ethical fading-bounded ethicality (\Omega). 

The rest of the data gives values of parameters or variables in the models. For instance, f - food fraud intention, f_{A} -actual response set from the survey tool/subjects, f_{T} -theoretical response set based on literature, \beta_{f} -difference ratio, and \Lambda -the difference between f_{T} and f_{A}.

title: An XAS study of P clustering in Si

description: Generating p- or n- type semiconductors through the introduction of either phosphorus (P) or boron (B) has underpinned the semiconductor industry for decades. As device scaling moves towards 3D structures, it is necessary to increase doping levels by 2 -3 orders of magnitude to several at.%. This comes with new material challenges as the spatial distribution of the dopants is unknown and can form clusters which influences their functional properties. Here we will use X-ray absorption spectroscopy recorded at the P K edge to probe the local atomic arrangement, clustering, and bonding around the P atoms in samples with 4 at. % doping. Data will be correlated with density function theory (which suggests clusters may form around vacancies) as well as resistivity measurements. The X-ray data will be compared with real space images determined from 3D atom probe and be used to benchmark that new metrology and its analysis protocols.

title: Data underlying the PhD thesis: Temperature-chemistry-microstructure correlations for alkali-activated binders

description: This collection of files contains raw and treated datasets utilized for the PhD thesis entitled 'Temperature-chemistry-microstructure correlations for alkali-activated binders'. The goal of this PhD project was to correlate intrinsic characteristics of precursors - chemical composition and glass structure, processing conditions - alkalinity of activator solution and curing temperature, and microstructural features of alkali-activated materials. The work initiated with the experimental characterization of precursors, made through X-ray diffraction and infrared and Raman spectroscopy, and proceeded with the study of kinetics of dissolution, assessed via inductively coupled plasma optical emission spectroscopy. The validity of the dissolution experiments was assessed via calculation of effective saturation indices of reaction products through thermodynamic models, performed with the GEMs software, assuring that the experiments were occurring within the forward dissolution regime of dissolution. In sequence, pastes of precursors made with different activators, prepared and cured in different conditions, were characterized at different ages. X-ray diffraction, differential thermogravimetric analysis, infrared spectroscopy and scanning electron microscopy were implemented to evaluate the evolution in reaction products and degree of reaction, correlating these features to the initial mix design and curing conditions. Finally, model pastes were modelled utilizing a combined kinetic-thermodynamic approach through the GeoMicro3D program. The simulations, based in principles of nucleation probability, reactive mass transport, and thermodynamic equilibrium, allowed the observations of digital microstructures at different ages, and the accuracy of the developed models was verified and positively validated against experimental scenarios implemented throughout the thesis. The 'readme.txt' file explains the contents of each individual file and how they were utilized for the manuscript.

title: Intrinsic viscosity of stud plant mucilage, Guar gum and Carboxymethyl cellulose blends

description: The data shows intrinsic viscosities (at infinity dilution) of polymeric blends of stud plant mucilage (SpM) with guar gum (GG) and carboxymethyl cellulose (CMC). Stud plant is a perennial plant that is found in abundance in southern and east Africa. Studies of synergism or interactions of stud plant mucilage with common gums can be of significance in optimizing its properties and widen its applications in various industries such as food or pharmaceutical. The data shows flow time in the Ostwald viscometer measured in a controlled water bath at 27+/-0.1 Degrees Celcius. The solution contains relative portions of stud plant mucilage with either guar gum or carboxymethyl cellulose, at a concentration of 0.05g/dL. The blends were in SpM to GG or CMC ratios (SpM:GG or SpM:CMC) of 100:0, 75:25, 50:50, 25:75 & 0:100. We further evaluate the effects of salt concentrations on the intrinsic viscosity of the blends at 0, 20 & 40mM. All tests were done in 3 replicates. The time in which the solution flows through the Ostwald viscosity was measured in seconds.
