The main aim of this study was to assess the ability of simple geometric measures of thunderstorm rainfall in explaining the runoff response from the watershed. For calculation of storm geometric properties (e.g. areal coverage of storm, areal coverage of the high-intensity portion of the storm, position of storm centroid and the movement of storm centroid in time), spatial information of rainf...

In this paper, bending analysis of concentric and eccentric beam stiffened square and rectangular plate using the meshless collocation method has been investigated. For detecting the governing equations of plate and beams, Mindlin plate theory and Timoshenko beam theory have been used, respectively, with the stiffness matrices of the plate and the beams obtained separately. The stiffness matric...

We determine the vegetation type for the CART from a database generated by the U. S. Geological Survey (USGS 1990). Soil types were provided by the Atmospheric Radiation Measurement (ARM) Program from the State Soil Geographic (STATSGO) database and mapped into the USDA classifications described by Clapp and Hornberger (1978). To provide the input parameters of temperature, pressure, humidity, ...

A Cartesian grid approach for the solution of the Euler equations within the framework of a patched, embedded Cartesian field mesh is described. As Cartesian grids are not necessarily body-aligned, an accurate representation for the surface boundary is important. In this paper a gridless boundary treatment using a cloud of nodes in the vicinity of the body combined with the multiquadric radial ...

Choosing an appropriate kernel is very important and critical when classifying a new problem with Support Vector Machine. So far, more attention has been paid on constructing new kernels and choosing suitable parameter values for a specific kernel function, but less on kernel selection. Furthermore, most of current kernel selection methods focus on seeking a best kernel with the highest classif...

We present a comparative study of soil CO2 flux (FCO2) measured by five groups (Groups 1-5) at the IAVCEI-CCVG Eighth Workshop on Volcanic Gases on Masaya volcano, Nicaragua. Groups 1-5 measured FCO2 using the accumulation chamber method at 5-m spacing within a 900 m grid during a morning (AM) period. These measurements were repeated by Groups 1-3 during an afternoon (PM) period. All measured F...

As a kernel independent algorithm, multilevel Green’s function interpolation method (MLGFIM) [1] [2] has been developed for electromagnetic problems from low frequency to fullwave simulation. This method inherits the multilevel tree structure of multilevel fast multipole algorithm (MLFMA) and adopts the interpolation technique of pre-corrected fast Fourier transform (PFFT). Compare with other f...

In a recent issue of the Journal of Economic Entomology, Arbogast et al. (2005) published an article upon which we are compelled to comment. The authors state that their article was in part “. . . to test the validity of contour mapping of trap catch for pest monitoring inwarehouses and retail stores.”The overall theme of the article was very good, and we share the authorsÕ excitement about the...

Geometric rectification of airborne multispectral scanner image data using traditional polynomial functions often cannot provide satisfactory RMSE accuracy due to the complex nature of geometric distortions in the data. The discrete approach to rectifying these data generates segmented pieces that may cause edge-matching problems after they are reassembled. To improve the rectification accuracy...

The synthesis of a dual-frequency band Inverted-S Antenna (ISA) using low profile PCB configuration is studied. To manipulate the multi-objectives and the huge amount of turning work involved in the synthesis of a dual-frequency band Inverted-S Antenna, special numerical techniques such as approaches to integrating different objectives, an improved vector genetic algorithm and a modified radial...
