Models that reproduce the observed high-velocity clouds (HVCs) also predict clouds at lower radial velocities that may easily be confused with Galactic disk (|z| < 1 kpc) gas. We describe the first search for these low-velocity halo clouds (LVHCs) using IRAS data and the initial data from the Galactic Arecibo L-band Feed Array survey in Hi (GALFA-Hi). The technique is based upon the expectation...

The results of in situ observations of the relative humidity in liquid, mixed, and ice clouds typically stratiform in nature and associated with mesoscale frontal systems at temperatures 45°C Ta 5°C are presented. The data were collected with the help of instrumentation deployed on the National Research Council (NRC) Convair-580. The length of sampled in-cloud space is approximately 23 10 km. T...

A methodology is described for testing the simulation of tropical convective clouds by models through comparison with observations of clouds and precipitation from earth-orbiting satellites. Clouds are divided into categories that represent convective cores: moderately thick anvil clouds and thin high clouds. Fractional abundances of these clouds are computed as a function of rain rate. A three...

Hydrodynamical simulations of jets interacting with clouds moving in the ambient medium of the host galaxy are presented. Clouds with sizes of the order of the jet diameter and smaller, crossing the path of the jet with different speeds are considered. In the case of slow moving clouds the jet is stopped over the brief period of time taken by the cloud to cross the jet. The jet maintains its ge...

The paper introduces a new, computationally inexpensive, real-time method of simulation of clouds for dynamic particle-based cloud rendering. The method covers such phenomena as atmospheric fronts, stable and unstable balance, thunderstorms, simplified simulation of middle and high clouds, correlation between wind and clouds and even tornadoes. The simulation is based on several simple numeric ...

Numerical experiments were carried out using the Tel-Aviv University 2-D cloud model to investigate the effects of increased concentrations of Cloud Condensation Nuclei (CCN), giant CCN (GCCN) and Ice Nuclei (IN) on the development of precipitation and cloud structure in mixedphase sub-tropical convective clouds. In order to differentiate between the contribution of the aerosols and the meteoro...

Suppose you had no ideas what fractals were, and you were asked to model objects like clouds, grass, plants, etc.. What else could you use to define the geometries of these objects? Although polynomials can easily define objects with smooth geometry, they are pretty useless if you want to model complex objects like grass or plants, since those possess infinitely non smooth, highly structured ge...

Cloud computing is a common buzz word in today’s computing environment where processing, storage, network and software are provided as an on demand service to their customers. The resources required by different users depend on their respective personalized applications. Advances in technologies on the other hand, lead to the migration from traditional desktop devices to smart mobile devices. R...

In this paper we present our task-based evaluation of query biased summarization for cross-language information retrieval (CLIR) using relevance prediction. We describe our 13 summarization methods each from one of four summarization strategies. We show how well our methods perform using Farsi text from the CLEF 2008 shared-task, which we translated to English automtatically. We report precisio...
