Abstract:
 The study utilized the fractal dimensions of the leaves of mangrove species locally found in the City of Tangub to determine if the same can be used for classification purposes. The species used were: Rhizophora mucronata, Avicennia marina, Pemphis acidula, Sonneratia alba and Acrostichum aureum. Findings revealed that fractal dimensions can be used to differentiate one mangrove species from another through their leaf roughness (f =14.400, p = 0.000). However, leaf fractal dimensions alone cannot differentiate the following mangrove species within groups: {Rhizopora mucronata and Avicenn

Abstract:
An application of fractal mathematics to the analysis of leaf shapes is presented. Six leaves randomly selected from nine tree species were used in the study. A video imaging method together with microcomputer-based image processing was used to generate leaf outlines. A fractal analysis program was written to calculate the fractal dimensions of the leaves. Recalling a leaf outline from a diskette and specifying both the starting position on it (e.g., the beginning of the petiole) and six step lengths (explained later), the program then generates the fractal dimension according to the theory de

Abstract:
Using a fractal analysis approach to study plant leaf venation and stem sections, we find that plants use very intelligent scaffolding strategies to tune mechanical strength of leaves and stems. Within plant organs, specialized types of tissues with different mechanical properties have evolved. Ideally, the biopolymers cellulose, hemicelluloses and lignin present in plant cell walls confer mechanical rigidity to plant tissues, but our studies reveal that the manner these biopolymers are distributed in the tissue matrix hold the key to the mechanical rigidity of the tissues.

Multivariate analysis was used to study some grapevine genotypes based on fractal parameters of leaf geometry.

Abstract:
Different types of plants make identification difficult. Therefore, we need a system that can identify the similarity of the leaves based on a reference leaf. Extraction can be done by taking one part of the plant and the most easily obtained part is the leaf part. Natural objects such as leaves have irregular shapes and are difficult to measure, but this can be overcome by using fractal dimensions. In this research, image detection of plant leaves will be carried out using the box counting method. The box counting method is a method of calculating fractal dimensions by dividing images into sm

Abstract:
In this paper, we present a method to estimate the fractal dimension of plant foliage in three dimensions (3D). This method is derived from the two-surface method introduced in the 90s to estimate the fractal dimension of tree species from field measurements on collections of trees. Here we adapted the method to individual plants. The multiscale topology and geometry of the plant must first be digitized in 3D. Then leafy branching systems of different sizes are constructed from the plant database, using the topological information. 3D convex envelops are then computed for each leafy branching

A wideband deltoid leaf fractal antenna is proposed for 5.8 GHz commonly used in industrial scientific and medical (ISM) and wireless local area networks (WLAN) applications. A microstrip patch antennas is designed with leaf shape radiating element. Using a leaf shape, it is possible to increase the perimeter of a design and thus reduce the overall dimensions of the antenna. A circular ring slot is made on the leaf shaped radiator, in a way that a circular disc is loaded at centre. Triangular fractal slots are made inside the circular disc to make it miniaturized.

In DLA, particles move about in random fashion, but stick together when they come into contact. Clumps of particles then form and grow further by colliding with other individual particles, or clumps of particles. Over time, one or more aggregates of individual particles will grow.

We discuss the sensitivity to initial conditions and the entropy production of low-dimensional conservative maps, focusing on situations where the phase space presents complex (fractal-like) structures.

We see how the Tsallis nonextensive formalism handles this situation both from a dynamical and from a statistical mechanics point of view….

Japanese elementary school teachers can teach art classes to elementary school students without receiving any art education. For this reason, there are no common evaluation criteria for art classes, and teachers create their own evaluation criteria and assign grades. The teachers' own evaluation criteria often include their own interests, suggesting that the students may not be receiving a fair evaluation. It is possible that elementary school students dislike art classes due to unfair evaluation. A dislike of art from an early age can lead to a lack of imagination and creativity. In addition,

A measure of this self-similar structure has been obtained by computing the fractal dimension of images visualizing the turbulence using the widely used box-counting method. If applied blindly, the box-counting method can lead to misleading results in which the edges of the scaling range, corresponding to the upper and lower length scales referred to above are incorporated in an incorrect way.
