Terrestrial laser scanned point cloud is a valuable data source for automatic building reconstruction. Detailed building facade structures from wall, roof, extrusion etc., can be recovered from the explicit three dimensional coordinates in the laser points. This paper presents our approach which generates building outlines semi-automatically from recognized building features. First, concave pol...

Ab initio CIS/6-311++G(d,p) calculations of geometry and vibrational frequencies have been carried out in the A state of tropolone. The grids of potential energy surfaces along the coordinates of high frequency tunneling vibration and the low-frequency coupled vibration have been calculated. Two-dimensional model potentials, formed from symmetric mode coupling potential and squeezed double well...

In the localisation stage, the two stacks are processed separately. Local maxima are assumed to originate from fluorophore beads, and a threshold value is then used to keep the prominent ones only [2]. Each one of these local maxima is then fitted with a PSF model, yielding the lateral and the axial coordinates of each fluorophore bead. The fitting error is further compared with a threshold val...

Isothermal and non-isothermal LES (Large Eddy Simulation) has been carried out to fully reproduce the characteristics of the flow field in eccentric annular channels, and rod bundles. The numerical approach is based upon boundary fitted coordinates and a fractional step algorithm; a dynamic Sub Grid Scale (SGS) model suited for this numerical environment has been implemented and tested for both...

Numerical simulation of the steady, laminar, forced convection heat transfer in the finned annulus is carried out for the case of fully developed incompressible flow corresponding to thermal boundary condition of uniform heat input per unit axial length with peripherally uniform temperature at any cross section. Boundary fitted curvilinear coordinates are used to overcome the singularities, bei...

This paper is part of an effort to examine the application of discontinuous Galerkin (DG) methods to the numerical modeling of the general circulation of the ocean. One step performed here is to develop an integral weak formulation of the lateral pressure forcing that is suitable for usage with a DG method and with a generalized vertical coordinate that includes level, terrain-fitted, isopycnic...

In RoboCup soccer, ball localization is an important and challenging task, especially since the last change of the rule which allows 50% of the ball’s surface to be of any color or pattern while the rest must remain white. Multi-color balls have changing color histograms and patterns in dependence of the current orientation and movement. This paper presents a neural approach using a convolution...

The variational Gaussian wavepacket (VGW) method in combination with the replica-exchange Monte Carlo is applied to calculations of the heat capacities of quantum water clusters, (H(2)O)(8) and (H(2)O)(10). The VGW method is most conveniently formulated in Cartesian coordinates. These in turn require the use of a flexible (i.e., unconstrained) water potential. When the latter is fitted as a lin...
