Emergency response systems in urban areas should be located to ensure adequate coverage and rapid response time. We develop a model for locating emergency vehicles on urban networks considering both spatial and temporal demand characteristics such as the p ...
We demonstrated high-speed photonic crystal nanocavity lasers with response time as short as similar to 2ps and direct modulation speeds exceeding 100GHz. Such high-speed characteristics are enabled by the use of cavity quantum electrodynamics effects such ...
LiF:Mg,Cu,P phosphors (commercially designated as MCP-N) are very sensitive thermoluminescent detectors and are considered by many laboratories to hold great promise for low level radiation monitoring. It is their high efficiency relative to TLDs based on ...
Novel optical sensing films for oxygen based on highly luminescent iridium (III) and ruthenium (II) complexes have been developed. These demonstrate excellent long-term photostability (several months) when incorporated into polystyrene membranes. The influ ...
We have experimentally studied the effects of gamma-radiation up to very high total doses on the physical properties of Brillouin scattering in standard commercially available optical fibres. A frequency variation of about 5 MHz for both Brillouin frequenc ...
Direct measurements of a collisionless current channel during driven magnetic reconnection are obtained for the first time on the Versatile Toroidal Facility. The size of the diffusion region is found to scale with the electron drift orbit width, independe ...
The invention concerns a 5-aminolevulinic acid ester (I) soln. for producing a pharmaceutical prepn. useful for diagnosing and/or treating tissue and/or cell pathologies by local radiation exposure using radiation emitted by a light source energy followed, ...
The effect of gamma radiation on the physical-chemical properties of sodium alginate Algimar has been investigated. Dilution viscometry, densitometry, and FTIR spectroscopy served to identify modifications. Decreasing intrinsic viscosities clearly revealed ...
The CORBA Object Group Service (OGS) is a new CORBA service that provides support for fault-tolerance through the replication of CORBA objects. In this paper, we present several optimization techniques that are used to improve the performance of OGS. For e ...
It is demonstrated that during the first few picoseconds after resonant femtosecond excitation the secondary radiation from a strongly coupled semiconductor microcavity containing one quantum well is dominated by Rayleigh scattered light. At early times af ...
