We study the liquid-vapor phase behavior of a polydisperse fluid using grand canonical simulations and moment free energy calculations. The strongly nonlinear variation of the fractional volume of liquid across the coexistence region prevents naive extrapolation from detecting the cloud point. We describe a finite-size scaling method which, nevertheless, permits accurate determination of cloud ...

aerosol formation due to ions in the atmosphere is not well understood, although it seems to play an important role in cloud formation. the ions in the atmosphere can enhance cloud formation and can increase nucleation as well as impeding the evaporation from the surfaces of the droplets. recently there has been some experimental work to find the relation between ions concentrations and cloud i...

This paper presents a method for segmenting a 3D point cloud into planar surfaces using recently obtained discretegeometry results. In discrete geometry, a discrete plane is defined as a set of grid points lying between two parallel planes with a small distance, called thickness. Contrarily to the continuous case, there exist a finite number of local geometric patterns (LGPs) appearing on discr...

This paper proposes a method for reconstructing a smooth and accurate 3D surface. Recent machine vision techniques can reconstruct accurate 3D points and normals of an object. The reconstructed point cloud is used for generating its 3D surface by surface reconstruction. The more accurate the point cloud, the more correct the surface becomes. For improving the surface, how to integrate existing ...

This paper reports on research into interactive, dynamic statistical graphics (DSG) applied to spatial data maintained within a geographic information system (GIS). We developed a bidirectional link between ArcView 2.1TM, a GIS, and XGobi, a DSG program. Multivariate data, collected at geographic locations, is passed from ArcView to XGobi and can be dynamically analyzed. The relation between th...

Today cloud computing technology is used everywhere. Cloud computing technology use increases due to its variety of facility. As cloud provide many facilities due to its vast area such that sharing of resources for different purposes scheduling become a necessary factor to discuss. In our paper different types of scheduling is applied in cloud computing network using servers on which load is ba...

We employ the first fully three-dimensional simulation to study the role of magnetic fields and ion-neutral friction in regulating gravitationally-driven fragmentation of molecular clouds. The cores in an initially subcritical cloud develop gradually over an ambipolar diffusion time while the cores in an initially supercritical cloud develop in a dynamical time. The infall speeds on to cores ar...

Cloud computing provides a platform that enables users to utilize computation, storage, and other computing resources on-demand. As the number of running nodes in the cloud increases, the potential points of failure and the complexity of recovering from error states grows correspondingly. Using the traditional cloud administrative interface to manually detect and recover from errors is tedious,...

Cloud computing has become a new era technology that has huge potentials in enterprises and markets. By using this technology, Cloud user can access applications and associated data from anywhere. It has many application for example, Companies are able to rent recourses from cloud for storage and other computational purposes so that infrastructure cost can be reduced significantly. For managing...

Recent development of laser scanning device increased the capability of representing rock outcrop in a very high resolution. Accurate 3D point cloud model with rock joint information can help geologist to estimate stability of rock slope on-site or off-site. An automatic plane extraction method was developed by computing normal directions and grouping them in similar direction. Point normal was...
