Faster - Better Molds Through RSP Tooling New Research and Advancements [PDF]

, 2004
The recent developments in rapid production tooling have all but made the need for prototype tooling disappear. There are several approaches that are now as fast and inexpensive as prototype tooling, and after part approval can continue to run in high ...

Absolute positions of 6.7-GHz methanol masers [PDF]

, 2009
The ATCA, MERLIN and VLA interferometers were used to measure the absolute positions of 35 6.7 GHz methanol masers to subarcsecond or higher accuracy. Our measurements represent essential preparatory data for Very Long Baseline Interferometry, which can ...

Accurate quantification of glass-forming ability by measuring effective volume relaxation of supercooled melt

APL Materials, 2017
Herein, we elucidate how to accurately quantify glass-forming ability (GFA) by measuring effective volume relaxation of supercooled melt. We propose a new parameter, denoted as κ, for representing the relaxation, which is calculated by combining ...

Accurate parallel form filter synthesis

Electronics Letters, 1996
Standard algorithms for synthesising parallel form digital filters are adequate for basic applications. However, recursive filters required in acoustics synthesis applications often have very high orders, and errors from filter synthesis can become intolerable. The authors describe a new method for synthesising parallel form recursive filters.

Impulse Correlation for Partially Filled Detonation Tubes [PDF]

, 2004
The effect of nozzles on the impulse obtained from a detonation tube of circular cross section has been the focus of many experimental and numerical studies. In these cases, the simplified detonation tube is closed at one end (forming the thrust surface)

The Herschel view of the dominant mode of galaxy growth from z=4 to the present day [PDF]

, 2015
We present an analysis of the deepest Herschel images in four major extragalactic fields GOODS-North, GOODS-South, UDS and COSMOS obtained within the GOODS-Herschel and CANDELS-Herschel key programs.

The influence of process parameters and sheet material on the temperature development in the forming zone

Manufacturing Review, 2019
Cold metal forming is a fast and economical way of producing a wide range of precise components. Its profitability mainly depends on part quality, process stability, and service intervals of tools.
