This study utilizes OSL-SAR, TL-SAR, and TL-MAAD methods to date heated quartz extracted from burnt clay pottery samples the Lingjiatan archaeological site, China. The OSL components of were determined by deconvoluting CW-OSL curve, Fast Ratio value was used distinguish whether initial signal dominated fast component. results show two types characteristics in signals: Type I is component (Fast ...

It is very difficult to obtain absolute historical datings of road features found at archaeological excavations. Nevertheless, various physical dating methods have been developed for this purpose, including Optical Stimulated Luminescence (OSL). After a small-scale campaign, samples from medieval trading route in the Veluwe area (central Netherlands) on sandy soils dated with OSL, order compare...

Background and Aim: Today, OSL (Optically Stimulated Luminescence) dosimetry system based on optical stimulation, includes systems that can meet many requirements for radiation protection in the field of medicine and space.  The Calcium Sulfide (CaS) is one of the earth's alkaline sulfide materials which can be used as a detector in this system. In this research, some of the dosimetry propertie...

An extensive series of 44 radiocarbon (14C) and 37 optically stimulated luminescence (OSL) ages have been obtained from the site of Riwi, south central Kimberley (NW Australia). As one of the earliest known Pleistocene sites in Australia, with archaeologically sterile sediment beneath deposits containing occupation, the chronology of the site is important in renewed debates surrounding the colo...

The loess stratigraphic boundary at the Pleistocene/Holocene transition defined by the magnetic susceptibility (MS) has previously been assumed to be synchronous with the Marine Isotope Stage (MIS) 2/1 boundary, and approximately time-synchronous at different sections across the Chinese Loess Plateau (CLP). However, although this assumption has been used as a basis for proxy-age model of Chines...

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...
