Abstract:
This paper presents the design and simulation of a G-shaped microstrip antenna operating at 3.7 GHz for 5G applications using ANSYS HFSS software. The antenna is fabricated on a substrate with dimensions 30x60 mm2. The G-shaped geometry is chosen for its compact size and improved bandwidth characteristics. The design process involves parameter optimization to achieve the desired resonant frequency and impedance matching. ANSYS HFSS simulations are utilized to analyze the antenna's performance in terms of return loss, radiation pattern, 3D polar plot and efficiency. The proposed antenna demonst

Abstract:
A four-band microstrip patch antenna is designed to work for satellite applications. Out of four bands, one of the bands has a wide band width up to 8 GHz. These microstrip patch antennas can work in the allocated range of 10–40 GHz. The antenna designed can have low return losses and positive gain, which indicates that it can work for practical applications. The designed antenna added stubs on all three corner sides of the microstrip patch antenna for impedance matching. The design used for VSAT applications is the ANSYS HFSS R21.

Abstract:
Three-dimensional (3D) laser scanning data can be used to characterize discontinuous rock masses in an unbiased, rapid, and accurate manner. With 3D laser scanning, it is now possible to measure rock faces whose access is restricted or rock slopes along highways or railway lines where working conditions are hazardous. The proposed method is less expensive than traditional manual survey and analysis methods. Laser scanning is a relatively new surveying technique that yields a so-called point cloud set of data; every single point represents a point in 3D space of the scanned rock surface. Becaus

Abstract:
Abstract The physical properties of underground material are anisotropic. This applies to all physical properties including resistivity. Anisotropic property is quantified by the anisotropic coefficient. The anisotropy of physical properties can be shown by 2D and or 3D modeling, but it is not always economically efficient for small-scale studies, while 1D modeling is not capable of showing the anisotropy effect. One of the many geophysical methods developed to learn about anisotropic properties under the earth is the azimuthal resistivity survey (ARS) which is the improvement of the vertical

This paper describes a technique for an automatic polar map creation from myocardial perfusion SPECT images. This exam is widely used in post-infarction patient evaluations, in order to foretell the outcome and left ventricular function. This exam is difficult to interpret, since it is a 3D representation of the heart. Use of polar maps intends to simplify analysis of the exam, converting the 3D image into a 2D plot. The technique developed is based on a combination of image registration and feature detection. For this study, an overall of 31 cases were tested, with the results compared with t

Abstract:
A hybrid nonlinear time domain seakeeping analysis is applied to the study of a container ship advancing at different headings and encounter frequencies. A time-domain nonlinear strip theory in six degrees-of-freedom has been extended to predict ship motions by solving the unsteady hydrodynamic problem in the frequency domain and the equations of motion in the time domain which allows introducing nonlinearities in the linear model. The code is used to make parametric roll predictions for various speeds and headings and the results are summarized in a very intuitive 2D and 3D polar plots showin
