Data visualization tools can help people conduct forms of analysis for which the human brain may be superior to computers, or for which understanding of an abstract context is required. Examples of such analyses are making comparisons between data sets to indentify trends, recognize patterns, and form hypothoses about relationships and casuality.

Diesel Aftertreatment Accelerated Aging Cycles (DAAAC) 
The EPA Final Rule for Emissions Durability Test Procedures (December 2005) provides a Standard Bench Cycle (SBC) for accelerated aging of emissions system components. The SBC can be used in place of the Standard Road Cycle (SRC) that requires vehicles to be driven for 120,000 miles, with periodic emissions measurements. Using the SBC offers significant savings in both time and expense to achieve the certification requirements. However, it cannot be used for diesel-fueled vehicles. Hence, all such vehicles must currently perform the full 120,000 mile SRC procedure. Based on input from industry, there was a strong desire to have a similar Diesel Aftertreatment Accelerated Aging Cycle (DAAAC) for diesel emissions components. At a DAAAC symposium on February 22, 2008, Southwest Research Institute offered the first proposal for an industry consortium to develop DAAAC aging procedures. Given the continued levels of interest in the DAAAC concept, SwRI was encouraged to continue with the initiative. The decision was made to concentrate on heavy-duty diesel aftertreatment systems. A proposal addressing heavy-duty diesel applications was sent out on July 11, 2008.
