Abstract:
The characterisation of geometric shapes produces their concise description and is, therefore, important for subsequent analyses, for example in Computer Vision, Machine Learning, or shape matching. A new method for extracting characterisation vectors of 2D geometric shapes is proposed in this paper. The shape of interest, embedded into a raster space, is swept several times by sweep-lines having different slopes. The interior shape’s points, being in the middle of its boundary and laying on the actual sweep-line, are identified at each stage of the sweeping process. The midpoints are then con

Abstract In this work, we grouped phytoplankton species according to their cell geometric shape for the first time in lake ecosystems. Field multiannual data were analyzed in order to understand the phytoplankton cell geometric shape distribution along the seasonal environmental variability in two Mediterranean lakes, a shallow natural lake and a deeper artificial lake. We characterized seasonally each lake on the basis of dominant phytoplankton cell geometric shapes, detecting the following common highlights comparing the two ecosystems: a complex and globular geometric shape (Cone + Half Sph

Abstract:
Searching for commonalities and recognizing distinguishing characteristics are important problem-solving strategies. During the study of geometry, students are bombarded with the properties of numerous geometric figures and can benefit from opportunities to integrate all these ideas. The game “Guess What?” is a stimulating vehicle for students to consider the unifying or distinguishing features of geometric figures.

Objective. In this paper, buildings of various shapes that have high seismic resistance are considered. Such seismic resistance is provided by the rational shape and outlines of the building itself. Here, the influence of the torsion of the building in the plan is minimized, thereby eliminating large stresses at the ends of the designed building. At the same time, the translational movement of the building in the plan is preserved.Method. By optimizing the shape and shape of buildings for various purposes, high efficiency of the structure is ensured under seismic effects. By comparing the shap

Since I started studying in Jewelry and Metalwork and Sculpture at the University of Iowa, I my artworks are still based on geometric shapes.

This thesis asserts that modern developments in technology have not been used as extensively as they could to aid blind people in their learning objectives. The same could also be said of many aspects of other areas of their lives. In particular in many countries blind students are discouraged from learning mathematics because of the intrinsically visual nature of many of the topics and particularly geometry. For many young people mathematics is also not a subject that is easily or willingly tackled. The research presented here has thus sort to answer whether a playful haptic environment could

Abstract:
Most of the work accomplished on surface blending is based on visual trimming. In the process of visual trimming, the unwanted portion of a surface is only hidden but not removed. Geometric trimming provides a complete mathematical description of the wanted portion of the trimming surface, and generates a new mathematical surface or sets of surface patches. The new surface is intended to resemble closely the corresponding portion of the original surface. A robust procedure is developed to geometrically trim the intersecting surfaces and blend the trimmed surface patches into one new surface.

The spiral channels themselves are embedded in the mandrel and have a characteristic u-shape in cross-section, which is dictated by the milling head used during manufacturing.

The current calculation methods for determining the tooth root load capacity of polymer gears (e.g., VDI 2736) are based on the same assumptions as those for steel gears.
