Pulsed OSL is applied to nine fine-grained sediment samples from Sichuan province, China, using stimulating pulses of 10 ms on and 240 ms off, with an infrared exposure prior to each OSL measurement. Comparison of fading rates between pulsed and non-pulsed signals, the latter also obtained with a preceding IR exposure, shows that fading is significant for mainly the non-pulsed signals. Presence...

The purpose of this paper is to test the appropriateness of OSL and electronic dosemeters to estimate eye lens doses at interventional cardiology environment. Using TLD as reference detectors, personal dose equivalent was measured in phantoms and during clinical procedures. For phantom measurements, OSL dose values resulted in an average difference of -15 % vs. TLD. Tests carried out with other...

We theoretically investigate an all-optical isolator under arbitrary linearly polarized fundamental wave (FW) input in an optical superlattice (OSL). The scheme is based on simultaneously phase matching the first-order Type I (oo-e) quasi-phase-matching (QPM) second-harmonic generation (SHG) process and higher-order Type 0 (ee-e) QPM SHG process in an OSL with a defect inserted in an asymmetric...

Thermoluminescence (TL) and optically stimulated luminescence (OSL) techniques are known as a research tools for the study of phosphor materials and for their applications in radiation dosimetry in particular [1]. Although TL technique is known since several decades, OSL is relatively newer technique. The TL or OSL emission from an irradiated sample arises upon stimulation with heat or light re...

We introduce a heuristic method for finding good, feasible solutions for multiproduct lot sizing problems with general assembly structures, multiple constrained resources, and nonzero setup costs and setup times. We evaluate the performance of this heuristic by comparing its solutions to optimal solutions of small randomly generated problems and to time-truncated Optimization Subroutine Library...

Natural calcium fluoride (fluorite CaF2:N) exhibits multiple LMOSL peaks when stimulated using blue LED’s, which makes it an unique phosphor. Such a property is not observed experimentally in any other dosimetric phosphors namely Al2O3:C, BeO etc. This makes CaF2:N as an effective tool not only for testing the kinetic models of luminescence but also for investigating OSL using CW and LM stimula...
