In an airborne photogrammetry, a geometrical modeling and object classification can be automated using color images. Stereo matching is an essential technique to reconstruct 3D model from images. Although, object classification methods are automated using height data estimated with the stereo matching, it is difficult to recognize construction materials, such as woods and concrete. The construc...

This work shows the process of characterization and modeling of integrated inductors in CMOS silicon technology for biotelemetry applications [1]. Three planar square inductors with different geometrical characteristics were designed, using the 2 μm CMOS technology of AMS. With physical models [2, 3] and the software ASITIC, was possible to define the geometrical characteristics of the inductor...

Research on room acoustic simulation focuses on more accurate modeling of wave effects in rooms. Today, also wave models (e.g., the boundary element method and the finite differences in time domain technique) can be used for higher frequencies, thus, in the geometrical acoustics (GA) domain. Simulations in architectural acoustics are powerful tools but their reliability depends on the input dat...

In this paper, we propose an effective method for gonio-spectral imaging of paper and cloth samples under oblique illumination conditions. High-resolution gonio-spectral images are synthesized from a basic spectral image and gonio-monochrome images. The method is based on gonio-spectral image fusion composed of two components, conventional spatial fusion and geometrical fusion. The proposed geo...

In this paper a representational language of a logical kind which is expressive enough to model concepts of descriptive geometry is presented. The language is employed to produce solid models of polyhedra from representations of their orthogonal projections. The synthetic process has as its input well-formed expressions representing the geometrical entities and relations of bidimensional orthog...

The bacterial Min protein system provides a major model system for studying reaction-diffusion processes in biology. Here we present the first in vitro study of the Min system in fully confined three-dimensional chambers that are lithography-defined, lipid-bilayer coated and isolated through pressure valves. We identify three typical dynamical behaviors that occur dependent on the geometrical c...

In a recent project the authors have proposed the adoption of Optimization Systems [1] as a bridging element between Computer-Aided Innovation (CAI) and PLM to identify geometrical contradictions [2], a particular case of the TRIZ physical contradiction [3]. A further development of the research [4] has revealed that the solutions obtained from several topological optimizations can be considere...

GeoSpelling as the basis of the Geometrical Product Specifications (GPS) standard [1] enables a comprehensive modeling framework and an unambiguous language to describe geometrical variations during the overall product life cycle. This is accomplished by providing a set of concepts and operations based on the fundamental concept of the “Skin Model”. However, the definition of GeoSpelling has no...
