Capital Gain Tax Overhang and Price Pressure
SSRN Electronic Journal, 2004ABSTRACTI study whether the capital gains tax is an impediment to selling by some investors and if so, to what degree associated delayed selling affects stock prices. I find that selling decisions by institutions serving tax‐sensitive clients are sensitive to cumulative capital gains, a pattern not observed for institutions with predominantly tax ...

Pressure sensors gaining durability
C&EN Global Enterprise, 2016Researchers in Singapore have done what most materials scientists can only dream about: They ran their project over with a car. But this act wasn’t born of frustration.

Fluid Mechanics of Pulse Pressure-Gain Combustors
46th AIAA Aerospace Sciences Meeting and Exhibit, 2008The fluid dynamic operation of a valveless pulse combustor has been studied experimentally and numerically. Through phase-locked chemiluminescence and pressure measurements it is shown that mechanical energy is created periodically in the flame surface, with an efficiency of 1.6%.

Autoignition in stratified mixtures for pressure gain combustion
Proceedings of the Combustion Institute, 2021The reliable generation of quasi-homogeneous autoignition inside a combustor fed by a continuous air flow would represent a milestone in realizing pressure gain combustion in gas turbines. In this work, the ignition distribution inside a stratified fuel–air mixture is analyzed. The ability of precise and reproducible injection of a desired fuel profile

Gain bandwidth products for capacitive pressure transducers
Applied Acoustics, 1994Abstract The compromise between the sensitivity and bandwidth of a pressure transducer using constant charge mode capacitive electro-mechanical transduction is examined. The performances of circular pressure summing diaphragms built around piston, plate and membrane structural elements are compared by defining a gain bandwidth product, analogous to ...

Dynamics of low-pressure gain-switched iodine lasers
Applied Physics Letters, 1995The dynamics of gain-switched, low-pressure photolytic iodine lasers were investigated experimentally and theoretically as a function of pressure and buffer gas. The behavior of the pulse shape, build-up, and duration can be explained by relaxation from a nonthermalized to a thermalized velocity distribution of the gas.

Stimulated Brillouin Gain Spectroscopy at High Pressures
1991The use of spontaneous Brillouin spectroscopy with a Fabry-Perot interferometer is a well established, powerful technique for studying thermally excited sound waves in liquids and solids1–4. There are well known problems associated with the Fabry-Perot interferometer, however.

A Simple Pressure-Gain Combustor for Gas Turbines
Journal of Engineering for Power, 1977The performance is presented, and a description is given, of a simple pressure-gain combustor, without moving parts, which has been shown, during laboratory trials, to produce a stagnation pressure-gain across the combustor in excess of 5 percent at a combustor stagnation temperature of 3:1.

Automation Dependency and Performance Gains under Time Pressure
Proceedings of the Human Factors and Ergonomics Society Annual Meeting, 2008Objective: An experiment tested a technique for encouraging appropriate human-automation interaction. Background: Operators often fail to make optimal use of automated aids, particularly when the aids are highly reliable. One way to discourage automation disuse might be to encourage automation dependence through time pressure.

Entropy Considerations on Integration of Pressure Gain Combustors
46th AIAA/ASME/SAE/ASEE Joint Propulsion Conference & Exhibit, 2010The primary goal of this study is to understand the issues associated with integrating the pressure-gain combustion device to a conventional steady state gas turbine engine. The loss of performance due to a poor integration method can be critical. Two types of transitional methods are examined using entropy-based models. An accumulator based transition
