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...

INTRODUCTION Friction measurements in orthodontics are often derived from models by using brackets placed on flat models with various straight wires. Dental arches are convex in some areas. The objectives of this study were to compare the frictional forces generated in conventional flat and convex dental arch setups, and to evaluate the effect of different archwires on friction in both dental a...

OBJECTIVE To evaluate the quantitative effects on torque expression of varying the slot size of stainless steel orthodontic brackets and the dimension of stainless steel wire, and to analyze the limitations of the experimental methods used. MATERIALS AND METHODS In vitro studies measuring torque expression in conventional and self-ligating stainless steel brackets with a torque-measuring devi...

This paper is devoted to the method developed in Ref. [1] for 3D reconstruction of the straight tracks in the tracking system consisting of the drift-chamber stereo layers. The method is based on the Hough-transform approach [2] – the discrete case of more general Radon transform [3] – and takes into account both coordinates of the hit wires and drift distances not only for the measurements in ...

We characterize the self-parallel (mitered) offsets of a general nonconvex polytope Q in 3-space and give a canonical algorithm that constructs a straight skeleton for Q.
