Aim: To estimate and compare the frictional forces engendered by three types of aestheticselfligating brackets with two straight wire alloys. Materials: The study comprised of a total of 90 brackets, of which 30 passive (Damon clear 2),30 active(GAC In-Ovation C) and 30 interactive (Empower clear) orthodontic brackets with a slot size of .022X.028 MBT prescription in combination with stainless ...

The main goals of wire electrical discharge machining (WEDM) manufacturers and users are to achieve a better stability and high productivity of the manufacturing process. The investigation on machinability of Aluminium Matrix Composite (AMC) using Wire-cut Electric Discharge Machining (WEDM) machine is constructed. The aim of this project to determine the most optimum machining parameter that w...

The e-glass fibre epoxy composite is a nonconductive ceramic material hence it is difficult to machine by any well known non-conventional machining methods like electrical discharge machining, wire electrical discharge machining etc. This material can be machined with conventional machining but compromise with accuracy, surface texture even not possible to micro slicing etc. Keeping in view, a ...

Wire arc additive manufacturing (WAAM) is a popular wire feed technology that creates components through the deposition of material layer-by-layer. WAAM has become promising alternative to conventional machining due its high rate, environmental friendliness, and cost-competitiveness. It used Fabricate complex shaped parts. The variable parameters are current, welding speed, shielding gas, gas f...

Traditional technologies and machines for sowing cereals lead to increased water erosion on sloping fields the washout of crops, respectively, causing a sharp decline in yields. The authors proposed anti-erosion technology machinery fields. research aims justify parameters ridge forming machine basic principles methods classical mechanics, mathematical analysis, statistics were used this study....

Currently, the research on application of bamboo wood plastic fibers to 3D printing technology in Vietnam is limited. Almost all studies mainly focus natural polymers (wood, rubber, coir..) but ignore a rich polymer source, popular Vietnam: bamboo. In addition, quality applied has not responded requirements consumers. The durability printed parts that based high. Surface gloss after implementat...

This paper describes an architecture of a machine translation system designed primarily for Slavic languages. The architecture is based upon a shallow transfer module and a stochastic ranker. The shallow transfer module helps to resolve the problems, which arise even in the translation of related languages, the stochastic ranker then chooses the best translation out of a set provided by a shall...
