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.

One of the properties of fractals is self-similarity which occurs when a fractal is enlarged. The fractal form has a pattern obtained from iterating a function with infinite repetition. Among the fractal shapes there is the Sierpinski carpet shape. Fractals in 2D form can be transformed using geometric concepts into

How can we improve geometry instruction at the preschool and primary levels? To answer that question, I conducted research to analyze young children's understanding of the geometric concepts of triangle and rectangle and to determine patterns in the development of this understanding from ages 3 through 6. The research suggests that early childhood educators need to rethink the way that basic shapes are introduced to young children. Since a basic understanding of shapes is essential to a future study of geometry, teachers need to focus on how best to help children develop that initial understan

Abstract:

The performance of the urban rail transit system depends largely on the operation efficiency of its feeder system. An improved way is proposed in this paper to calculate the accessibility index which is used for evaluation of feeder lines, and both passengers’ waiting time and the competition between different access modes are considered. Different from previous research, this paper focuses on whether and how the geometric shape differences affect the performance of fixed-route feeder lines. The impacts of line shape on accessibility are analysed by derived formulas for calculating accessibili

Abstract:

The role of geometric shape properties in determining the perceived orientation (heading) change of picture elements was investigated in four experiments. In experiment 1 the systematic change in perceived heading of each of a depicted team of horses which projected irregular geometric shapes was measured. In experiment 2, involving silhouettes, the perceptual axes of these same horse shapes, together with those of a pair of enantiomorphic deltoid shapes, were derived. These derived shape axes were used in experiment 3, along with single oblique contours, to determine the degree of heading shi

Abstract:

Unlike the means of distributions on a euclidean space, it is not entirely clear how one should define the means of distributions on the size-and-shape or shape spaces of k labelled points in ℝm since these spaces are all curved. In this paper, we discuss, from a shape-theoretic point of view, some questions which arise in practice while using procrustean methods to define mean size-and-shapes or shapes. We obtain sufficient conditions for such means to be unique and for the corresponding generalized procrustean algorithms to converge to them. These conditions involve the curvature of the size

The article has developed algorithms for the control of measuring measuring measures of the measuring and measuring hand for remote measurements. Algorithms for assessing the accuracy of remote measurements of parts with complex geometric shape are proposed. The principle of operation of V-shaped probes is described. A critical analysis of the specification of requirements for accuracy for measuring parts with complex geometric shapes was carried out. The main sources of measurement errors are investigated by means of a coordinate-measuring hand.

Abstract:

Mastery of geometric shapes in children can be seen from how the child is able to mention and understand geometric shapes, connect and sort geometric shapes, as well as show, express, and tell the results of work in the form of geometry. Mastery of geometric shapes in children can be improved by activities that make children active, one of which is mosaic activities. Mosaic activity is the excitement of sticking to pieces made of certain material. This study aims to improve the mastery of geometric shapes in early childhood using mosaic activities. The method used is a quantitative method with

In this study, an artificial neural network model was developed to predict the geometric shapes of different objects using image processing. These objects with various sizes and shapes (circle, square, triangle, and rectangle) were used for the experimental process. In order to extract the features of these geometric shapes, morphological features, including the area, perimeter, compactness, elongation, rectangularity, and roundness, were applied. For the artificial neural network modeling, the standard back-propagation algorithm was found to be the optimum choice for training the model. In th
