The Illusion of Requirements in Software Development

Kavli Affiliate: Daniel Ralph| First 5 Authors: Paul Ralph, Paul Ralph, , , | Summary:It is widely accepted that understanding system requirements is important for software development project success. However, this paper presents two novel challenges to the requirements concept. First, where many plausible approaches to achieving a goal are evident, there may be insufficient […]

Application of machine learning algorithms to the study of noise artifacts in gravitational-wave data

Kavli Affiliate: Erotokritos Katsavounidis | Summary:The sensitivity of searches for astrophysical transients in data from the LIGO is generally limited by the presence of transient, non-Gaussian noise artifacts, which occur at a high-enough rate such that accidental coincidence across multiple detectors is non-negligible. Furthermore, non-Gaussian noise artifacts typically dominate over the background contributed from stationary […]

Design and operation of a microfabricated phonon spectrometer utilizing superconducting tunnel junctions as phonon transducers

Kavli Affiliate: Richard D. Robinson | Summary:In order to fully understand nanoscale heat transport it is necessary to spectrally characterize phonon transmission in nanostructures. Towards this goal we have developed a microfabricated phonon spectrometer. We utilize microfabricated superconducting tunnel junction-based (STJ) phonon transducers for the emission and detection of tunable, non-thermal, and spectrally resolved acoustic […]

The Two Paradigms of Software Design

Kavli Affiliate: Daniel Ralph| First 5 Authors: Paul Ralph, Paul Ralph, , , | Summary:The dominant view of design in information systems and software engineering, the Rational Design Paradigm, views software development as a methodical, plan-centered, approximately rational process of optimizing a design candidate for known constraints and objectives. This paper synthesizes an Alternative Design […]

Planck 2013 results X. Energetic particle effects: characterization, removal, and simulation

Kavli Affiliate: E. P. S. Shellard | Summary:We describe the detection, interpretation, and removal of the signal resulting from interactions of high energy particles with the Planck High Frequency Instrument (HFI). There are two types of interactions: heating of the 0.1,K bolometer plate; and glitches in each detector time stream. The transient responses to detector […]
