In this work, we assessed the possible relation of ionospheric perturbations observed by Detection of Electro-Magnetic Emissions Transmitted from Earthquake Regions (DEMETER), Global Positioning System total electron content (GPS TEC), National Oceanic and Atmospheric markbroyard.com Administration (NOAA)-derived outgoing longwave-Earth radiation (
The markbroyard.com pursuit of esthetic excellence has become a major goal in the dental treatment and orthodontic treatment.The beauty of the smile is not only constituted by the shape, position, and size of the teeth, but also based on the characteristics of the gingival tissue and conformation of the lips, which should be as harmonious as teeth.
3D printing has recently become an affordable means of producing bespoke here models and parts.This has now been extended to models produced from medical imaging, such as computed tomography (CT).Here we report the production of a selection of 3D models to compliment the available imaging data for a 12-month-old child with double-outlet right ventr
The goal of this paper is to design a robust controller for controlling a pendulum system.The control of nonlinear systems is a common problem that is facing the researchers in control systems design.The Sliding Mode Controller (SMC) is the best solution for controlling a nonlinear system.The classical SMC consists from two phases.The first phase i
