Electric discharge machining (EDM) is a ‘newer technology utilized to machine hard metals, alloys, composites and ceramics. This paper reports the experimental investigation carried out on EDM to study the effects of machining parameters such as pulsed current on material removal rate, depth of cut, overcut, tool wear (net weight lost) and hardness on En-31 tool steel The work material was elec...

The Functional Transformation Method (FTM) is an established method for sound synthesis by physical modeling, which has proven its feasibility so far by the application to strings and membranes. Based on integral transformations, it provides a discrete solution for continuous physical problems given in form of initialboundary-value problems. This paper extends the range of applications of the F...

Demand for lead-free, free-cutting brass is increasing in response to lead regulations Europe. The authors of this paper have attempted develop a lead-free with an α + β two-phase microstructure, which different from existing C6932 alloy. As result basic investigations, it was found that the addition Si β-brass dramatically reduces cutting resistance due effect appears be reduction stacking def...

A frequency-domain numerical model of brass instrument sound production is proposed as a tool to predict their brassiness, defined as the rate of spectral enrichment with increasing dynamic level. It is based on generalized Burger's equations dedicated to weakly nonlinear wave propagation in nonuniform ducts, and is an extension of previous work by Menguy and Gilbert [Acta Acustica 86, 798-810 ...

The purpose of this paper is to provide an explanation the process making glass gamelan which has recently become a topic discussion among musicians musical arts. Musical art intangible form heritage from historical civilization in chanting music originating gamelan. In general, made bronze, iron, or brass. So it different with Song Meri Studio, studio tries innovate by introducing glass. This ...

"This paper contains an application of the orphanhood method for estimating adult mortality, based on information provided during the period 1888-1910 by the brides and bridegrooms of six parishes of the Central Valley of Costa Rica.... Using the Brass technique for estimating adult mortality from orphanhood and interpolating the resulting probabilities of surviving into... Coale and Demeny's r...

Demonstrations provide a descriptive medium for specifying robotic tasks. Prior work has shown that robots can acquire a range of complex skills through demonstration, such as table tennis (Mülling et al., 2013), lane following (Pomerleau, 1989), pouring water (Pastor et al., 2009), drawer opening (Rana et al., 2017), and multi-stage manipulation tasks (Zhang et al., 2018). However, the most ef...

An electron probe microanalyzer (EPMA) with a palm-size chamber including the electron source and the sample stage was developed using a pyroelectric crystal. Energy of obtained continuous X-rays and lower limits of detection of transition metals (titanium, iron, and nickel) were evaluated. End point energy (Duane-Hunt limit) of obtained continuous X-rays was about 40 keV, but the palm-size EPM...

This paper presents some initial findings regarding the influence of First Language on playing brass instruments. Using ultrasound imaging of the tongue, vowel production and sustained trombone notes were compared for a New Zealand English and a Tongan speaker. It is suggested that, during trombone playing, the tongue shapes used by the Tongan participant pattern with the back vowel /o/ while t...
