Graphene based different types of slotted antennas have been designed and compared with respect to slot position, return Loss, voltage standing wave ratio, bandwidth and radiation pattern. Different patch materials, patch shapes, position and inclination of slots in these antennas can alter their performance. This paper comprises with the performance comparison of different shaped microstrip patch antennas i.e. H shape, E shape, Z shape, L shape, T shape and P shape using CST Microwave Studio Suite to operate in the frequency limit of 2.6 GHz to 4 GHz.

Abstract:

AbstractCostal cartilage grafting is a commonly used reconstruction procedure, particularly in rhinoplasty. Although costal cartilage is broadly used in reconstructive surgery, there are differing opinions regarding which costal cartilage levels provide the most ideal grafts. Grafts are typically designed to match the shape of the recipient site. The shapes of costal cartilage grafts have been described as “boat-shaped,” “C-shaped,” “canoe-shaped,” “U-shaped,” “crescent-shaped,” “L-shaped,” “semilunar,” “straight,” and “Y-shaped.” The shapes of costal cartilages are thought to lend themselves

Abstract:

Shape of workpiece, electrode orientation and flushing system play important role in electrical discharge machining (EDM) process. Low material removal rate and relatively high electrode wear ratio are some of the disadvantages of EDM process. This can be due to the flushing modes. Workpiece shape has a significant effect in effectiveness of dielectric flushing flow and orientation during EDM process. This research work is conducted to analyze the influence of various workpiece shapes. Square cavity, L shape, flat shape and U shape were machined with same cross-section electrode material. Test

Generally, the configuration of the substation grounding system is in the form of a grid or mesh, where several conductor rods are installed vertically and horizontally or combined with conductor rods planted deep in the ground from each point or not. The substation configuration is very complex because of the many variables used in accordance with IEEE Standard 80-2013. This variable also influences the allowable and actual magnitude of the step voltage and touch voltage. The substation grounding system configuration can be designed in several shapes including rectangular, square, L-shaped an

Abstract:

Leaf shape is closely related to economics of leaf support and leaf functions, including light interception, water use, and CO2 uptake, so correct quantification of leaf shape is helpful for studies of leaf structure/function relationships. There are some extant indices for quantifying leaf shape, including the leaf width/length ratio (W/L), leaf shape fractal dimension (FD), leaf dissection index, leaf roundness index, standardized bilateral symmetrical index, etc. W/L ratio is the simplest to calculate, and recent studies have shown the importance of the W/L ratio in explaining the scaling e

This approach reflects the shape of a major part of soil minerals. It was shown, that even the simplest case of the suggested low-resolution harmonics technique with L = 1 showed sufficient accuracy

However, there is a significant gap between the generated node-edge graphs and the representation of shape appearance. To address these problems, we propose an improved generative design

Abstract:

Most of the results about the L-shapes of double-loop networks are given in terms of the four parameters ℓ, h, p, n. But these parameters are not well defined in the degenerate case. Recently, Cheng and Hwang proposed an efficient algorithm to compute the four parameters ℓ, h, p, n of an L-shape which works for both the regular and the degenerate cases. On the other hand, Chen and Hwang gave a set of rules to determine the four parameters ℓ, h, p, n of a degenerate L-shape. Unfortunately, the solutions given by the above two methods do not always coincide. In this paper, we investigate their r

Abstract:

In this study four species from Solanaceae family was conducted. These four species belong to four different genera (Solanum L. ? Physalis L. ?Withania Pauq. ? Lycium L.) The study included morphological characters of sex organs and their pollen grains for these Iraqi wild plants.The results showed that the position of epipetalous stamens , the shape of anther, their dimensions ,and the length of filaments are important taxonomical characters .On the others hand the shape of their ovaries and stigmas are also important characters in distinguish between these four species .Pollen grains are sim

Abstract:

The solar light bulb is a one-liter bottle filled with water that uses the refraction of sunlight. In many places, it is not expected the consumption of 1-liter bottles but other capacities. This study shows the effect of the shape of the PET bottles and how the capacity influences the luminous flux resulting from the solar refraction. A total of nine solar bulb models were used with different shapes and capacities (600 mL, 1 L, and 1.5 L). The results showed no interaction between the two factors where the best luminous flux was obtained using the 1 L and 1.5 L bottles regardless of the shape

Abstract:

<p>Electrical discharges that happen near high-voltage conductors are known as corona discharges. It will produce light and sound as it ionises the surrounding air. The purpose of this work is to investigate how conductor form and spacing affect the properties of corona discharge produced by a plasma generator. In this study, conductor shapes such as triangle, W-shaped wire, syringe (point), and L-shaped wire (horizontal) were experimented with, as well as the distance between conductors. The outcome demonstrates that conductor spacing affects the corona discharge's plasma intensity, wit

Abstract:

Longidorus mindanaoensis n. sp. is described from samples associated with riverine mangroves in the Philippines and is the first Longidorus species collected from such a habitat. Its relationship within the genus is inferred from molecular and morphological data. Phylogenetic inferences were performed for D2-D3 and SSU rDNA using appropriate phylogenetic algorithms. The new species is characterised by a thickened basal layer of the body cuticle with prominent spiral fibres, a dome-shaped continuous lip region, an oval to elliptical fovea with pore-like opening, the guiding ring at 2.2-2.5 lip

Abstract:

Silver nanoparticles (AgNPs) are increasingly used in various consumer products, leading to their inadvertent release in aquatic ecosystems. The toxicity of AgNPs could be associated with the leaching of ionic Ag but also with the size, shape and surface properties. The purpose of this study was to test the null hypothesis that toxicity of AgNPs was independent of shape in the invertebrate Hydra vulgaris. The hydranths were exposed to increasing concentrations of ionic Ag and AgNPs of three different shapes (spherical, cubic and prismatic) with the same size and coating (polyvinylpyrrolidone).

Abstract:

The characteristic shape changes observed in the growth and division of L-form cells have been explained by several theoretical studies and simulations using a vesicle model in which the membrane area increases with time. In those theoretical studies, characteristic shapes such as tubulation and budding were reproduced in a non-equilibrium state, but it was not possible to incorporate deformations that would change the topology of the membrane. We constructed a vesicle model in which the area of the membrane increases using coarse-grained particles and analyzed the changes in the shape of grow

Abstract:

In this paper we consider two topological transforms that are popular in applied topology: the Persistent Homology Transform and the Euler Characteristic Transform. Both of these transforms are of interest for their mathematical properties as well as their applications to science and engineering, because they provide a way of summarizing shapes in a topological, yet quantitative, way. Both transforms take a shape, viewed as a tame subset M M of R d \mathbb { R}^d , and associates to each direction v ∈ S d − 1 v\in S^{d-1} a shape summary obtained by scanning M M in the direction v v .

Abstract:

In this paper, the size and shape characteristics of desert sand particles were quantitatively investigated via a combination of X-CT scanning and spherical harmonics functions. The size characteristics of the desert sand particles were evaluated via the Length (L), Width (W), Thickness (T), and Volume equivalent spherical diameter (VESD). The average value of the VESD for the desert sand particle is 118.2 μm, which is much smaller than that of commonly used fine aggregate, and more than 90% particles are smaller than 150 μm. The overall shape of the desert sand particles was assessed with two
