Abstract: Almost all process compressors manufactured today are built in accordance with the fixed geometry modular system. It is not always possible to accurately predict the operational behavior of a ...

Abstract: A parameterization is presented for the optical properties of water clouds in the infrared spectrum. The cloud optical properties are parameterized in terms of the cloud?s liquid water content and the effective radius ...

Abstract: In this paper we discuss the use of a modal domain optical fiber sensor (MD sensor) as a component in an active control system to suppress vibrations in a flexible beam. An MD sensor ...

Abstract: Quantitative relationships for converting recorded water levels to discharge records in urban streams typically have high levels of uncertainty, particularly for high flows. This problem results from the inherent difficulty ...

Abstract: The wear of dynamic sealing elements, i.e., elements that seal against a moving counter-surface, is highly complex. In dry-running reciprocating compressors, these sealing elements, commonly referred to as packing rings, ...

Abstract: Techniques to remove, suppress, and control the chaotic behavior of nonlinear systems are reviewed. Analysis of a forced damped nonlinear oscillator provides a brief overview of the relevant ...

Abstract: We consider proofmass actuators for vibration suppression in flexible structures. Proofmass actuators appear to have a significant force-to-weight ratio over other types of actuators; hence, there ...

Abstract: Moisture levels in medical device packages influence a variety of crucial device properties, e.g. mechanical properties, corrosion and leach rates, drug potency, and ultimately shelf life. This ...

Abstract: The photocatalytic activity of a novel anatase titanium dioxide powder, namely Sachtleben Hombikat UV 100, has been investigated and compared with that of a well-studied material (i.e., Degussa ...
