WebFeb 23, 2024 · The accurate reconstruction of a defective part of the mandible is a time-consuming task in maxillofacial surgery. In order to design accurate 3D implants quickly, a method for generating a mandibular defect implant model based on deep learning was proposed. First, an algorithm for generating a defective mandible 3D model randomly … WebWhere a dedicated ground ct, sensitive earth protection and high impedance fault (HIZ) detection is required, additional models can be ordered that include a fourth ct input. The dedicated ground ct affords ground overcurrent protection via an external residual connection or window ct while the SEF ct option provides both SEF and HIZ protection. tame my hair

A residually connected ground relay is widely used to protect medium-voltage systems. The actual ground current is measured by CTs that are interconnected in such a way that the ground relay responds to a current proportional to the ground-fault current. The term residual in common usage is normally … See more The core-balance method is based on primary current phasor addition or flux summation. The remaining zero-sequence component, if any, is then transformed to the secondary. The core-balance CT or sensor is the basis of … See more Ground-return relaying is illustrated in Figure 4. The ground-fault current returns through theCT in the neutral-bus to ground-bus connection. For feeder circuits, an insulating segment may be introduced in busway … See more Factors that affect the sensitivity of ground-fault sensing include the following: 1. Circuit-charging current drawn by surge arrestors, shielded … See more A generic term, ground differential is used for a variety of schemes that utilize phasor or algebraic subtraction or addition of signals. The currents may be produced by any of the … See more WebApr 14, 2024 · The laser-melted metal substructure ensured the necessary rigidity of the connection to the eyeglasses and the minimum thickness to work in the reduced space between the external surface of the prosthesis and the underlining residual skin tissues of the nasal pyramid.
