Verification of complex codes

Ober, Curtis C.

Over the past several years, verifying and validating complex codes at Sandia National Laboratories has become a major part of code development. These aspects tackle two important parts of simulation modeling: determining if the models have been correctly implemented - verification, and determining if the correct models have been selected - validation. In this talk, we will focus on verification and discuss the basics of code verification and its application to a few codes and problems at Sandia.

Pedestrian and traffic safety in parking lots at SNL/NM : audit background report

Sanchez, Paul E.

This report supplements audit 2008-E-0009, conducted by the ES&H, Quality, Safeguards & Security Audits Department, 12870, during fall and winter of FY 2008. The study evaluates slips, trips and falls, the leading cause of reportable injuries at Sandia. In 2007, almost half of over 100 of such incidents occurred in parking lots. During the course of the audit, over 5000 observations were collected in 10 parking lots across SNL/NM. Based on benchmarks and trends of pedestrian behavior, the report proposes pedestrian-friendly features and attributes to improve pedestrian safety in parking lots. Less safe pedestrian behavior is associated with older parking lots lacking pedestrian-friendly features and attributes, like those for buildings 823, 887 and 811. Conversely, safer pedestrian behavior is associated with newer parking lots that have designated walkways, intra-lot walkways and sidewalks. Observations also revealed that motorists are in widespread noncompliance with parking lot speed limits and stop signs and markers.
