The California Air Resources Board (ARB) undertook this study to characterize the in-use emissions of model year (MY) 2010 or newer diesel engines. Emissions from four trucks: one equipped with an exhaust gas recirculation (EGR) and three equipped wi

We show that the maximum induced matching problem can be solved on hhd-free graphs in O(m2) time; hhd-free graphs generalize chordal graphs and the previous best bound was O(m3). Then, we consider a technique used by Brandstädt and Hoàng (2008) [4]

This paper highlights the effect of emissions regulations on in-use emissions from heavy-duty vehicles powered by different model year engines. More importantly, fuel economy data for pre- and post-consent decree engines are compared. The objective o

This paper reports the results of modal analysis performed to determine the episodic nature of events and emissions for engine operation within the not-to-exceed (NTE) zone, for each of the selected routes. West Virginia University developed a portab

The formation of a self-organized lateral superlattice has been observed in (AlAs)m(GaAs)n short-period superlattices grown on vicinal GaAs(100) surfaces by molecular beam epitaxy. The lateral period is given by the substrate step periodicity. It is

Strained InGaAs quantum wires have been grown on holographically-patterned (100) GaAs substrates using alternating molecular beam epitaxy. Transmission electron micrographs reveal that the initial grating has rough sidewalls from wet-etching, but the

Quasi-periodic facetting has been observed during high temperature, molecular beam epitaxial-growth of AlAs and AlAs/GaAs superlattices. The facetting is shown to be related to the thickness of the AlAs epilayers and is unrelated to the number of int

The refuse truck segment of the heavy duty diesel vehicle population has been identified as the most fuel inefficient sector. This is predominantly due to the stop and go driving pattern associated with these trucks. Constantly evolving emissions nor
