Laboratory measurements of the upward intensity distribution in young thin sea ice illustrate the variation of this distribution and peak intensity with growth temperature and ice thickness.

PURPOSE The most common metric for comparing measured to calculated dose planes is a pass rate generated using percent difference, distance-to-agreement (DTA), or some combination of the two (e.g. gamma evaluation). The grid of analyzed points often corresponds to a dosimeter array with low areal-density of point detectors. This work examines the statistical uncertainty of planar dose compariso...

In our previous studies, we noted a non-uniform distribution of protein tracer preferentially entering the anterior stromal lamellae of the cornea from the limbus. Given other differences reported previously between the anterior and posterior lamellae of the cornea, and the number of corneal disorders in which abnormalities are preferentially confined to either the anterior or posterior lamella...

From an engineering point of view, the effect of light intensity distribution on the stability of growth rate should be taken into account in designing effective photobioreactors and sustaining stable growth rates. In the experiments described here, in order to keep operational parameters at an almost constant level, a semi-continuous culture method was developed for cultivation of photosynthet...

The photonic interactions between a focused Gaussian laser beam and a nanoscopic particle are highly dependent on exact particle location and focal intensity distribution. So far, the 3D focal intensity distribution and the preferred position of a nanoparticle confined within the focal region were only theoretically predicted. Here, we directly map the three-dimensional focal intensity distribu...

turbulent mixed convection of a nanofluid (water/al2o3, φ=.02) has been studied numerically. two-phase mixture model has been used to investigate the effects of nanoparticles mean diameter on the flow parameters. nanoparticles distribution at the tube cross section shows that the particles are uniformly dispersed. the non-uniformity of the particles distribution occurs in the case of large nano...

Time resolved laser induced incandescence (LII) technique is used to measure size distribution of soot nanoparticles of candle's flame. Pulsed Nd:YAG laser is used to heat nanoparticles to incandescence temperature and the resulting signal is measured. Mass and energy balance equations are numerically solved to calculate temperature of soot particles in low fluence regime. Assuming Plank black ...

conclusions following cabg, the most severity of pain was reported at surgical incision on time t2. pain began to decrease from the third day following the operation. age, sex and bmi along with operation-related factors such as duration of cbp or chest tube drainage may affect the pain pattern following cabg surgery. patients and methods the present study was conducted on 138 patients who unde...

The efficient characterization of sites contaminated with unexploded ordnance (UXO) is necessary prior to returning these sites to the public domain. Characterization plans must be based on an accurate prediction of the UXO distribution. A doubly stochastic Poisson process is proposed as the underlying model controlling the spatial distribution of UXO. This model allows the single parameter (in...
