We analyzed the characteristics of white porcelain fired at different temperatures (800, 1200, 1350℃) by measuring changes in thermal luminescence(TL) and multi-wavelength (IR, orange, green, blue, UVA) optically stimulated luminescence(OSL) signal. White 800℃ showed high intensity TL signals over a wide temperature range 100 to 400℃, whereas 1200 1350℃ peaks 210℃. Moreover, OSL 800℃, increased...

Alexander V. Konstantinou Autonomic computing has been proposed as an approach to reducing the cost and complexity of managing Information Technology (IT) infrastructure. An autonomic system is one that is self-configuring, self-optimizing, self-healing and self-protecting. Such a system requires minimal administration, mostly involving policy-level management. This thesis introduces novel resu...

The paper presents the results of optical dating of potassium-rich feldspar grains obtained from the Haua Fteah cave in Cyrenaica, northeast Libya, focussing on the chronology of the Deep Sounding excavated by Charles McBurney in the 1950s and re-excavated recently. Samples were also collected from a 1.25 m-deep trench (Trench S) excavated during the present project below the basal level of the...

During the penultimate glaciation vast areas of the Alps were glaciated, with piedmont glaciers protruding into the foreland. In the easternmost part of the northward draining valleys of the Alps, the glaciers did not reach the foreland, but formed valley glaciers confined by the mountainous terrain. This also applies to the Ybbs valley, where samples for luminescence dating out of glaciofluvia...

Abstract Purpose This study compared the effects of offset loading (OSL) versus traditional (TDL) in bench press exercise on pectoral muscle thickness and strength over a 4-week mesocycle. Methods: Twenty male participants aged 18–45 years with at least 5 experience one-repetition maximum equal to or greater than their body mass were randomly assigned OSL TDL groups. Before after mesocycle, was...

The objective of this paper is to review the use thermoluminescence (TL) and optically stimulated luminescence (OSL) techniques as research tools in luminescence, particularly detect presence trapping centers that can degrade efficiency scintillators, shape properties persistent phosphors, storage phosphors dosimeters. A brief main analysis provided, followed by a discussion their limitations. ...

The well-known thermoluminescent material LiF:Mg,Cu,P (MCP) was previously shown to emit significant optically stimulated luminescence (OSL). In this paper, we investigate the rate of OSL recombination processes in MCP, expressed as effective lifetimes, using time-correlated single photon counting, context often referred time-resolved pulsed OSL. fell into two categories: (i) a dominant fast de...

optically stimulated luminescence (osl) is currently one of the most important dating methods. it dates the last exposure to sunlight. natural hazard evidences such as colluvial wedges, alluvial and fluvial sediments can be dated by osl. therefore, osl plays an important role in studies related to paleoseismology and tectonic activity, particularly in arid and semi- arid regions. the altai moun...

Localized electronic recombination processes in donor–acceptor pairs of luminescent materials have been recently modeled using a new kinetic model based on tunneling. Within this model, recombination is assumed to take place via the excited state of the donor, and nearest-neighbor recombinations take place within a random distribution of centers. An approximate semi-analytical version of the mo...
