This paper describes a new musical instrument inspired by the pedal-steel guitar, along with its motivations and other considerations. Creating a multi-dimensional, expressive instrument was the primary driving force. For these criteria the pedal steel guitar proved an apt model as it allows control over several instrument parameters simultaneously and continuously. The parameters we wanted con...

There are numerous advantages to exploiting diffraction-limited instrumentation at astronomical observatories, which include smaller footprints, less mechanical and thermal instabilities and high levels of performance. To realize such instrumentation it is imperative to convert the atmospheric seeing-limited signal that is captured by the telescope into a diffraction-limited signal. This proces...

The multivariable feedback system tracking error is related to the sensitivity matrix S = [I + L]–1and to the uncertainty of plant and instrumentation. The ‘popular' highly interacting 2×2 distillation column problem is solved in a novel manner.

Article: Each term, when covering the history of management, many students have difficulty identifying with “ancient” management figures such as Frederick Taylor and Frank and Lillian Gilbreth. Even in Birmingham, Alabama, the former “Pittsburgh of the South,” Taylor‟s pig iron studies have little relevance. The bricklaying, sewing, and surgery studies by the Gilbreths fare only slightly better...

The dynamics of large networks is known to be complex. In this paper, we study a characterization of network dynamics in terms of transit times and losses. Applicability of this characterization is studied through experimental evaluation of connections on the Internet using instrumentation at the kernel level as well as at the application level. The results of this study indicate that this char...

The utility of nondestructive laser Raman for testing the biogenicity of microfossil-like structures in ancient rocks is promising, yet results from deposits like the ∼3.46 Ga Apex chert remain contentious. The essence of the debate is that associated microstructures, which are not purported to be microfossils, also contain reduced carbon that displays Raman D- and G-band peaks similar to those...

Let F be a life distribution with survival function F = 1 F and 00 — finite mean y * j n F(x)dx. The scaled total time on test transform -1 F ( t ) — <P,,(t) = /n /F(x)dx/y was introduced by Barlow and Campo (1975) as a r U tool in the statistical analysis of life data. The properties IFR, IFRA, NBUE, DMRL and heavy-tailedness can be translated to properties of tp„(t). r We discuss the previous...
