Experiments on co-combustion of municipal solid waste (MSW) and coal were conducted in a bubbling fluidized bed (BFB). The MSW sample was pretreated through hydrothermal treatment (HT) for obtaining uniform characteristics. MSW blending ratios as 10%, 20%, 30% and 50% were selected and tested at...

Using data from 1995 and 1996, we estimate the cost of the Arizona Enhanced I/M Program and the emission reductions achieved. We begin by enumerating briefly the components of I/M costs and discuss their size and incidence. Then we describe the empirical information from Arizona and how we use...

The purpose of this econometric analysis is to model the concentration of particle number emissions from a hybrid diesel-electric bus in terms of operating characteristics. Important aspects of this study are that particle number concentrations are modeled instead of particle mass, and the...

With perpetual strains on resources, road agencies need to develop network-level decision-making frameworks to ensure optimum resource allocation. This is especially true for intelligent transport systems (ITS) and, in particular, variable message signs (VMSs), a key component of incident...
