On the performance characteristics of multiple pass hydrogen fluoride chemical laser master oscillator/power amplifiers
The performance of a cw Hydrogen Fluoride (HF) chemical laser master oscillator with power amplifier was measured as a function of input power, the number of passes through the gain media, location of the optical axis of the input beam and oscillator/amplifier flow field match/mismatch. The …

The Detection of Neuropsychological Malingering
… Test. The statistical concepts of floor effect, performance curve, and magnitude of error were examined. Additionally, the statistical differences in the responses of the five groups were analyzed to determine cutting scores for use in distinguishing malingerers from nonmalingerers.

Mathematical modelling of applied heat transfer in temperature sensitive packaging systems. Design, development and validation of a heat transfer model using lumped system approach that predicts the performance of cold chain packaging systems under dynamically changing environmental thermal conditions.
… tests that are carried out to understand system performance in different internal and external conditions. This MPhil project aims at solving this problem through the development of a transient spreadsheet based model using lumped system approach that predicts the performance of packaging systems …

Analysis of resource control in nondeterministic mobile ad hoc network systems : an unmanned aerial vehicle example
… a supplier node in order to characterize system performance and analyze the effects of change on the system. The connectivity, or information sharing, was based on distance and since every node moved around a defined space, the connectivity of the graph changed constantly. Several different …

Many is beautiful : commoditization as a source of disruptive innovation
… commodities. The sudden availability of a high performance factor input at a low price often enables innovation in adjacent market segments. The thesis suggests main five reasons that commodities spur innovation: ** The emergence of a commodity collapses competition to the single dimension of …

On the spectral information content of vowels
… (F2) is the crucial feature, as the vowel performance drops dramatically once it has been suppressed. The confusions indicate that listeners are also using the first formant (F1). Results from the high-pass filter conditions indicate the same. For many of the vowels, the vowel performance …

An impulse framework for hydrodynamic force analysis : fish propulsion, water entry of spheres, and marine propellers
… water entry of spheres, and the offdesign performance of marine propellers. These seemingly-unrelated physics problems share a key common thread: The forces on these fish, spheres, and propellers can be modeled as the sum of the reaction to the rate of change of (1) the pressure impulse …
