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 ...

"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...

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...

AE monitoring from various types of stress corrosion cracking (SCC) has been conducted for the past 15 years in our laboratory. This paper discusses AE results of active-path dissolution-type SCC of austenitic stainless steel in chloride solution and fused salt, fluoride and polythionic acid solutions, brass in ammonia (Mattosson's solution), and carbon steels in nitrite solution. Transgranular...

the micro wire electrical discharge machining (micro wire-edm) process is a modern machining process with various applications in manufacturing micro-parts. the recast layer remaining on the machined surfaces is an inevitable complication of this process. this layer can subsequently affect the machined parts performance. to optimize the recast layer in the micro wire-edm of the molybdenum micro...

The size and length effects of an inclusion on multi-pass copper shaped-wire drawing were investigated. For this purpose, an experimental investigation on optimal die half-angle was conducted. Based on experimental data of optimal die half-angle, wire and inclusion deformations, drawing and hydrostatic stress of copper shaped-wires that contain an inclusion were calculated by two-dimensional fi...

When an individual loses their website and a backup cannot be found, they can download and run Warrick, a webrepository crawler which will recover their lost website by crawling the holdings of the Internet Archive and several search engine caches. Running Warrick locally requires some technical know-how, so we have created an on-line queueing system called Brass which simplifies the task of re...
