This final report describes the study that has been supported through the National Aeronautics and Space Administration (NASA) microgravity grants program from February 2004 through March 2007. This work was a continuation of a NASA microgravity grant that
The paper evaluates performance of finned-tube evaporators at different refrigerant exit superheats to assess the impact of longitudinal heat conduction on capacity.

On September 22, 2005 the National Institute of Standards and Technology (NIST) conducted a demonstration of two prototype tactical decision aid computer interfaces in the city of Wilson, North Carolina. Members of the City of Wilson Fire Department
Aircraft fire suppression applications inherently demanding performance requirements, made all the more challenging by low temperature conditions, physical inaccessibility, and high and possibly uncertain air flow conditions, have been historically
The 2004 Construction Users Roundtable (CURT) report, Collaboration, Integrated Information, and the Project Life Cycle in Building Design, Construction and Operation (WP-1202), makes clear that there is a compelling need to improve project delivery
Smokeview is a software tool designed to visualize numerical calculations generated by fire models such as the Fire Dynamics Simulator (FDS), a computational fluid dynamics (CFD) model of fire-driven fluid flow or CFAST, a zone fire model. Smokeview

Predicting the rheological properties of fresh concrete, mortars, and cement paste from first principles remains a great challenge. While progress has been made in modeling the rheological properties of idealized hard sphere-like suspensions, there is
As the potential of computer modeling of hydration and microstructure development of cement-based materials approaches realization, the development of virtual standard test methods becomes a viable possibility. In creating these virtual standards, just as
In the twenty-first century, most high-performance concretes, and many other ordinary concretes, are now based on blended cements that contain silica fume, slag, and/or fly ash additions. Because the chemical shrinkage accompanying the pozzolanic and
The United Nations Centre for Trade Facilitation and Electronic Business (UN/CEFACT) has as its primary objective the delivery of simple, transparent processes for international trade, thereby making the activities between the buyer, the seller and the
Motivated by recent efforts to mitigate blast loading using energy-absorbing materials, this paper investigates the mechanics of uniaxial crushing of cellular sandwich plates under air blast loading using analytical and computational modeling. This model
Database-assisted design (DAD) is a methodology of designing structures for wind loads that makes direct use of pressure time series from wind tunnel tests. This paper presents interpolation procedures that enable application of the DAD approach for cases

A series of new reduced-scale compartment fire experiments were conducted, which included local measurements of temperature and species composition. The measurements are unique to the compartment fire literature. By design, the experiments provided a
