Adding memory to pressure-sensitive phosphors [PDF]

, 2019
Mechanoluminescence (ML) is the phenomenon describing the emission of light during mechanical action on a solid, leading to applications such as pressure sensing, damage detection and visualization of stress distributions.

Aeolianite and barrier dune construction spanning the last two glacial-interglacial cycles from the southern Cape coast, South Africa [PDF]

, 2004
The southern Cape region of South Africa has extensive coastal aeolianites and barrier dunes. Whilst previously reported, limited knowledge of their age has precluded an understanding of their relationship with the climatic and sea-level fluctuations ...

Exploring the relationships between Electron Spin Resonance (ESR)/Luminescence (OSL/TL) properties and trace element composition from quartz in various bedrocks (Strengbach catchment, Vosges) [PDF]

Geochronology
Quartz Thermoluminescence (TL), Optically Stimulated Luminescence (OSL) and Electron Spin Resonance (ESR) offer valuable quantitative tools both for understanding sediment provenance and surface processes.

Radiation-induced growth and isothermal decay of infrared-stimulated luminescence from feldspar [PDF]

, 2015
Optically stimulated luminescence (OSL) ages can determine a wide range of geological events or processes, such as the timing of sediment deposition, the exposure duration of a rock surface, or the cooling rate of bedrock.

Study of optically stimulated luminescence in K2SO4:Ce

Radiation Protection and Environment, 2018
Highly sensitive cerium-doped K2SO4phosphor was synthesized for optically stimulated luminescence (OSL) properties. The present study mainly investigated various kinetic parameters and correlation between the thermoluminescence and OSL (TL-OSL) processes.

Radiocarbon and OSL dating on cores from the Chaoshan delta in the coastal South China Sea

Frontiers in Marine Science, 2022
Accurate chronology plays a crucial role in reconstructing delta evolution. Radiocarbon (14C) and optically stimulated luminescence (OSL) dating are widely used to establish a stratigraphic chronology of the late Quaternary sediments.

Optically-stimulated luminescence profiling and dating of historic agricultural terraces in Catalonia (Spain) [PDF]

, 2017
Dating agricultural terraces is a notoriously difficult problem for archaeologists. The frequent occurrence of residual material in terrace soils and the potential for post-depositional disturbance mean that conventional artefactual and lab-based dating ...

Luminescence properties of common salt (NaCl) available in Nigeria for use as accident dosimeter in radiological emergency situation

Journal of Radiation Research and Applied Sciences, 2017
In the event of a radiological accident or attack, it is important to assess and quantify radiation dose to the population. This could be done using materials in the vicinity that are sensitive to ionizing radiation.

On the Combination of Logistic Regression and Local Probability Estimates

, 2009
In this paper we give a survey of the combination of classifiers. We briefly describe basic principles of machine learning and the problem of classifier construction and review several approaches to generate different classifiers as well as established ...
