Evolutionary Computation Approach to Heat Exchanger Design

Author(s)
David A. Yashar, Janusz Wojusiak, Kenneth Kaufman, Piotr A. Domanski
The efficiency of a vapor compression system is strongly influenced by the performance of the finned-tube heat exchangers it employs. Heat exchanger performance

Optimal timing of wildfire prevention education

Author(s)
David T. Butry, Jeffrey P. Prestemon, Karen L. Abt
Public outreach and wildfire education activities have been shown to limit the number of unintentional human-caused ignitions (i.e., accidental wildfires). Such

Ultra-Precision Linear Motion Metrology

The objective of this study is to investigate the role of ZnO nanoparticles in the life cycle of a waterborne polyurethane (PU) nanocomposite during UV exposure

Tunable laser spectroscopy referenced with dual frequency combs

Author(s)
Fabrizio R. Giorgetta, Ian R. Coddington, Esther Baumann, William C. Swann, Nathan R. Newbury
Frequency combs provide broadband spectroscopic measurements with high frequency accuracy and precision. However, because the comb power is distributed over a

Sensitivity scaling of dual frequency comb spectroscopy

Author(s)
Ian R. Coddington, William C. Swann, Nathan R. Newbury
Coherent dual comb spectroscopy can harness many inherent strengths of frequency combs to provide high-resolution, high-accuracy measurements of a sample

Test Collection Diagnosis and Treatment

Author(s)
Ian M. Soboroff
Test collections are a mainstay of information retrieval research. Since the 1990s, large reusable test collections have been developed in the context of

Introduction to Surface Finish Metrology

Author(s)
