There is a striking increase in the availability of statistical data in the Linked Open Data (LOD) cloud, and the Cube vocabulary has become the de facto standard for the description of multi-dimensional data. However, the reuse of a standard vocabulary needs to pair with modeling strategies that make it easy to locate, consume and integrate information. In this paper, we developed a quantitati...

User participation has become paramount for any successful data warehouse initiative. In this paper, we present MD2, a tool based on the dimensional data modeling approach, which facilitates the user participation in the development of a data warehouse application. MD2 assists users on identifying their analytical needs in order to help data warehouse designers to better specify business requir...

Abstract A three-dimensional model of intense bunched beams is developed for cylindrical and corrugated conducting pipes. Updated comparisons between the current limits derived from this model and experimental data from PPM focusing klystrons are presented. An electrostatic Green’s function is formulated for azimuthally symmetric slowwave structures. Analytical and numerical results are present...

Today’s geometric modeling tools are usually controlled by the mouse and keyboard. 3dmodeling operations are often constrained to planes or lines to make modeling easier. New augmented reality devices promise new classes of applications with natural 3d user interfaces. This paper deals with a new method that enables users to model 3d shapes directly with their fingers. It is implemented in Arti...

INTRODUCTION In order to reduce source/drain resistance with shallower junction, self-aligned silicide(sa1icide) process was developed and is finding more applications to MOSFETs. Now, MOSFET process simulation including salicide process is a necessity. However, there have been few reports on salicide simulation mainly because the implement of 2D model is very difficult. We have developed a 2D ...

In this paper the application of a novel CW FM Laser radar is demonstrated through the acquisition of a three dimensional model of the world famous "David" by Donatello. The steps of the acquisition procedure and the related technical solutions are reported. The scientific focus was centered on the processing pipeline simplification due to this new acquisition methodology. Detailed results are ...

Accurate and economical modeling of near-surface transport processes is a standing challenge for various engineering atmospheric boundary-layer flows. In this paper, we address by utilizing an stochastic one-dimensional turbulence (ODT) model. ODT aims to resolve all relevant scales turbulent flow domain. Here applied channel as stand-alone tool. The domain wall-normal line that aligned with th...
