The present paper reports the implementation of a neural network technique to predict ground settlement as occasioned by dewatering activities of a long-term large-scale drainage project. The objective of the project is to lower and maintain the level of the ground water table in urban areas through a system of a non-stop pumping wells whose layout and operation rate are determined and implemen...

in spain, camping accommodation accounted for 6.32% of total tourism accommodation and 8.2% of overnight stays in 2007. there were 1,152 registered campsites which provided lodging for almost 6.4 million users. although these figures are higher than those of rural accommodation, few studies have analyzed the main attributes of this sector and their contribution to the development of spanish tou...

Thermal measurements on a GaAs/AlGaAs heterostructure reveal that the state of the confined two-dimensional electrons dramatically affects the nuclear-spin diffusion near Landau level filling factor ν=1. The experiments provide quantitative evidence that the sharp peak in the temperature dependence of heat capacity near ν=1 is due to an enhanced nuclear-spin diffusion from the GaAs quantum well...

Scanning near-field optical spectroscopy was applied to semipolar ð20 2 1Þ InGaN/GaN quantum wells (QWs) to evaluate spatial homogeneity of QW band gap and its dependence on the growth conditions. In the most uniform QW, photoluminescence (PL) spectra were found to be narrow with small peak wavelength and spectral width variations. A QW grown at reduced temperature showed sub-micrometer size PL...

Concern has mounted over health effects caused by exposure to flame retardant additives used in consumer products. Significant research efforts have focused particularly on exposure to polybrominated diphenyl ethers (PBDEs) used in furniture and electronic applications. However, little attention has focused on applications in textiles, particularly textiles meeting a flammability standard known...

We observe ultralong-range blueshifted Cs(2) molecular states near ns(1/2) Rydberg states in an optical dipole trap, where 31≤n≤34. The accidental near degeneracy of (n-4)l and ns Rydberg states for l>2 in Cs, due to the small fractional ns quantum defect, leads to nonadiabatic coupling among these states, producing potential wells above the ns thresholds. Two important consequences of admixing...
