The preadjusted orthodontic appliance has improved the efficiency and effectiveness of the orthodontist in achieving good final results for patients in general. However, the orthodontist is limited in achieving excellent final results because of individual patient variation from the prescription of the preadjusted appliance as well as the orthodontist's ability to precisely place the appliance....

We introduce additively-weighted straight skeletons as a new generalization of straight skeletons. An additively-weighted straight skeleton is the result of a wavefront-propagation process where, unlike in previous variants of straight skeletons, wavefront edges do not necessarily start to move at the begin of the propagation process but at later points in time. We analyze the properties of add...

Abstract Wearable body weight support systems can assist individuals with mobility impairments in performing daily living activities greater ease and independence. However, existing have limitations terms of balancing their strength, compact size, interaction the ground, driving. In this paper, we present High-Strength Flexible Mechanism (HSFM) designed for support. The HSFM utilizes a coiling ...

In this article, a mathematical model has been developed for calculating the energy-power parameters of drawing process in monolithic dies on straight-line machines, and its adequacy validated experimental wire laboratory automated machine. The program allows us to calculate stress, force, tensile strength yield alloy after drawing, safety factor, power. differs that it evaluate uniformity defo...

Single staggered is a design development of normal wire and tube heat exchanger that wires are welded with staggered configuration on two sides. Capacity of wire and tube heat exchanger is the ability of the heat exchanger to release heat. The objective of this study is to analyse the effect of wire pitch (pw) on capacity of single staggered wire and tube heat exchanger. The research...

Wire arc additive manufacturing (WAAM) is one of the less-explored metal 3D printing technologies that hold up a huge potential for large-scale product across multiple industries. The low-cost AM uses energy as heat source and metallic wire feedstock material. process sustainable supports green manufacturing. However, major challenge associated with WAAM management leads to development residual...

Magnetic domain walls created and propagated in curved permally nanowires under continuous pulsed fields a Lorentz microscope. Using such aims to create single or multiple magnetic typical areas of those structures, an external field then applies along the long axis these nanowires. Following that are from one end other each wire by increasing continuous/pulsed strength. At increased value, Fre...
