Metrics for Manipulation and Enhancements of Forensic Images

Completed
Image metrics and well-defined algorithms will be researched and developed to analyze and quantify the image transformation processes applied by forensic scientists in the context of latent fingerprint analysis. The research will focus on two principal aspects. Image Enhancement Tools The

Metrics for Reactive Wetting in Complex Systems

Completed
From fundamental physical considerations, we have derived a set of partial differential equations describing wetting and spreading. These equations are derived using a variational thermodynamic principle applied to a two-component alloy system with three (vapor, liquid and solid) phases. The method

Metrics and Tools for Construction Productivity Project

Ongoing
What is the problem? Although the construction industry is a major sector of the U.S. economy, it has experienced a perceived period of decline in productivity[1]. Due to the critical lack of measurement methods, however, the magnitude of the productivity problem in the construction industry is

Metrologies for Nanobiomaterials in Artificial Photosynthesis

pH Metrology

Ongoing
The suite of NIST pH SRMs forms the basis for pH measurements in the United States, and pH is the most-often-measured chemical quantity. Hence this NIST work directly or indirectly impacts a large number of users in industry, government, and academia. One of the most critical set of users is in
Cardiac Leads

Metrology for Cardiac Leads

Ongoing
Quantifying cardiac lead reliability is not an easy task because of the vastly different conditions under which leads must operate under when installed in a human body. The committee is actively involved in many aspects of cardiac lead reliability including: gage repeatability and reproducibility
