Considerations for Numerical Modeling of Inverted Wings in Ground Effects

T HE series of experiments conducted by Zerihan [1], Zerihan and Zhang [2,3], and Zhang and Zerihan [4–6] on an 80% scale model of the front wing of the 1998 Tyrell Formula One car (here referred to as the T-026 profile, based on a modified NASA GA(W) LS(1)-0413) have justifiably become the go-to source of validation for researchers investigating single and double element wings in ground effect...

Research considerations for more effective groundwater monitoring.

Since numerous pathogens occur in feces, water is monitored for fecal contamination using indicator organisms rather than individual pathogens. Although this approach is supported by health effects data in recreational waters, it is questionable when used for drinking water. Most outbreaks in groundwater occur in systems that have not violated the US EPA's maximum contaminant limit (MCL) for to...

Considerations for effective rank based noise attenuation

Incoherent noise attenuation remains a challenging problem in seismic data processing. While many tools are successful at removing noise, this often comes at the expense of some signal. We seek the ideal noise attenuator– one that is effective, practical, and above all safe. Multichannel Singular Spectrum Analysis (MSSA) is a step in this direction. MSSA exploits the spatial redundancy of data ...

Scenario support for effective requirements

Scenarios are widely used as requirements, and the quality of requirements is an important factor in the efficiency and success of a development project. The informal nature of scenarios requires that analysts do much manual work with them, and much tedious and detailed effort is needed to make a collection of scenarios well-defined, relatively complete, minimal, and coherent. We discuss six as...
