DART weather data
No full textoai:archive.researchdata.leeds.ac.uk:1At each study location 2 weather stations were installed (4 in total), each monitoring every 30 minutes rainfall, temperature, humidity, wind speed, wind direction and barometric pressure with 1 at each location additionally having a Solar and UV radiation sensor. 2 stations were chosen at each location to allow for a high degree of spatial resolution and to provide redundancy. The weather data combined with the in-situ soil measurements allow the assessment of the seasonal variations of the geophysical soil properties and vegetation mark formation as a result of varying weather patterns aiming to identify the biggest contrast between archaeological features and the surrounding soil matrix
Characterisation of calcium phosphates after femtosecond laser irradiation
No full textA mixture of calcium phosphate (in the form of mineral brushite) powder with a bio-mineral gel was used to coat acid eroded bovine enamel surfaces. After forming the mineral layers, the samples were irradiated with two different 100-200 fs pulsed lasers, one at 800 nm with 1 kHz repetition rate, and the other at 1044nm with 1 GHz repetition rate. The laser-irradiated samples were characterized using X-ray diffraction, SEM, and Raman microscopy
COGNITO: Activity monitoring and recovery
Get PDFIn order to test our hierarchical framework, we have obtained two datasets using an egocentric setup. These datasets consist of non-periodic manipulative tasks in an industrial context. All the sequences were captured with on-body sensors consisting IMUs, a backpack-mounted RGB-D camera for top-view and a chestmounted fisheye camera for front-view of the workbench. The first dataset is the scenario of hammering nails and driving screws. In this dataset, subjects are asked to hammer 3 nails and drive 3 screws using prescribed tools. The second dataset is a labelling and packaging bottles scenario. In this dataset, participants asked to attach labels to two bottles, then package them in the correct positions within a box. This requires opening the box, placing the bottles, closing the box, and then writing on the box as completed using a marker pen
Dataset relating to 'Apertureless near-field terahertz imaging using the self-mixing effect in a quantum cascade laser'
No full textThis dataset relates to data presented in the work, 'Apertureless near-field terahertz imaging using the self-mixing effect in a quantum cascade laser'. In this work we report two-dimensional apertureless near-field terahertz (THz) imaging using a quantum cascade laser (QCL) source and scattering probe, and demonstrate a resolution of ~1 μm (~λ/100), which represents the highest value achieved to date with a THz QCL. By employing a detection scheme based on self-mixing interferometry, our approach offers experimental simplicity by removing the need for an external detector, and also provides sensitivity to the phase of the reinjected field. We demonstrate a near-field enhancement of the scattered field amplitude for small probe-sample separations, and investigate how the phase of the reinjected field varies with the round-trip time in the external cavity
Parameterised contact model of pelvic bone and cartilage: development data set
Get PDFThe dataset was created as supplementary materials for the paper "Geometric parameterisation of pelvic bone and cartilage in contact analysis of the natural hip: an initial study". The dataset included the following documentation and data: the comparison results between segmentation-based model and parameterised model and the sensitivity analysis for the segmentation-based model; the detailed methodology of FE model development for segmentation-based model and parameterised model; the FE models for the two types of models and the solid models of the components for the two types of models
Polarised Raman Spectroscopy data of dimer liquid crystals
No full textPolarised Raman Spectroscopy (PRS) is used to quantify the orientational order in the conventional (N) and twist-bend (NTB) nematic phases of a homologous series of liquid crystalline dimers. The dimers investigated have 7, 8, 9 and 11 methylene groups connecting two cyanobiphenyl mesogens and data for 4-pentyl-4ʹ-cyanobiphenyl (5CB) and 4-octyl-4ʹ-cyanobiphenyl (8CB) are included for comparison. This data file includes the source data (polarised Raman spectra for the materials, deduced at various temperatures and for a series of orientation angles with respect to the input and output polarisation direction of the laser light). These spectra are in the file format produced by the Renishaw Raman microscope used, suitable for GRAMMS software. The data file also includes the depolarised Raman intensities for each of the materials at the selected temperatures as Excel files
China useful work and exergy analysis data: 1971-2030
No full textThis dataset contains the base datasets and mapping process used to undertake the 1971-2030 China exergy analysis for the Applied Energy journal article at this link: http://dx.doi.org/10.1016/j.apenergy.2015.05.082. The datasets sets out the mapping (from primary energy to useful work categories), the task-level exergy efficiencies (i.e. the second law thermodynamic efficiencies that convert from primary exergy to useful work), and the detailed results (i.e. task-level values of useful work) for the 1971-2010 data period
MINDSEYE2015: Joint Tracking and Event Analysis for Carried Object Detection.
No full textMINDSEYE2015 is a dataset of videos showing a variety of people interacting with various different objects. It was primarily created to improve carried object tracking using event analysis. It consists of 15 videos (5 recordings captured from 3 viewpoints), each lasting approximately 6000 frames. These videos have a resolution of 360x640 at 20 frames per second and are taken from three different viewpoints which allows for a better evaluation in dealing with object occlusions. In the majority of frames there are at most one person and one object, but there are cases of more or less than one person or object present in the scene. Since the dataset was captured outdoors, the movement of trees and cloths on the table, as well as the change in brightness of the video due to clouds and distance of the person to the camera cause challenges for object detectors. We have defined 7 events, namely Carry, Static, Pickup, Putdown, Drop, Raise and Roll, to allow for a full description of the scene with regards to the state of the carried object, from the start of its appearance to its disappearance. Ground truth for person tracks, carried object tracks and events are fully annotated. Carried object detections, tracklets and tracks are also provided. For more information please visit:
