This study demonstrated an approach to modeling individual vehicle second-by-second fuel consumption and emissions on the basis of vehicle operations. The approach used the Motor Vehicle Emission Simulator (MOVES)–Matrix, a high-performance vehicle emissions modeling system consisting of a multidimensional array of vehicle emissions rates (pulled directly from EPA’s MOVES emissions model) that could be quickly queried by other models to generate an applicable emissions rate for any specified on-road fleet and operating conditions. For this project, the research team developed a spreadsheet-based MOVES-Matrix calculator to simplify connecting vehicle activity data with multidimensional emissions rates from MOVES-Matrix. This paper provides a walk-through of the calculation procedures, from basic vehicle information and driving cycles to second-by-second emissions rates. The individual vehicle emissions modeling framework was incorporated into Commute Warrior, a trademarked travel survey application for Android smartphones, to provide real-time fuel consumption and emissions rate estimates from concurrently obtained GPS-based speed data.

Hymns for the Fallen listens closely to forty years of Hollywood combat films produced after Vietnam. Ever a noisy genre, post-Vietnam war films have deployed music and sound to place the audience in the midst of battle and to stimulate reflection on the experience of combat. Considering landmark movies—such as Apocalypse Now, Saving Private Ryan, The Thin Red Line, Black Hawk Down, The Hurt Locker, and American Sniper—as well as lesser known films, Todd Decker shows how the domain of sound, an experientially rich, culturally resonant aspect of the cinema, not only invokes the realities of war, but also shapes the American audience’s engagement with soldiers and veterans as flesh-and-blood representatives of the nation. Hymns for the Fallen explores all three elements of film sound—dialogue, sound effects, music—and considers how expressive and formal choices on the soundtrack have turned the serious war film into a patriotic ritual enacted in the commercial space of the cinema.
