Some physico-chemical properties and the concentrations of the metals Fe, Mn, Ni, Cd, Cr, Co, Cu, Pb, and Zn in water and sediments were examined from September 2011 to January 2012 in Bodo Creek, where oil spills have been recurrent. Temperature, pH, total dissolved solid, conductivity, salinity, dissolved oxygen, biological oxygen demand (BOD), chemical oxygen demand (COD), total hardness, su...

Title of Dissertation: DYNAMIC ORIGIN-DESTINATION DEMAND ESTIMATION AND PREDICTION FOR OFF-LINE AND ON-LINE DYNAMIC TRAFFIC ASSIGNMENT OPERATION Xuesong Zhou, Ph.D., 2004 Dissertation Directed By: Professor Hani S. Mahmassani, Department of Civil and Environmental Engineering Time-dependent Origin-Destination (OD) demand information is a fundamental input for Dynamic Traffic Assignment (DTA) mo...

This paper studies the supply management of a primary input, where this input gives rise to multiple products in fixed proportions. My objective is twofold. First, I study fixed proportions technology under demand uncertainty in comparison with flexible and the dedicated technologies. I show that fixed proportions technology has a costpooling value over dedicated technology, which is larger tha...

The decline of China's energy intensity slowed since 2000. During 2002–2005 it actually increased, reversing the long-term trend. Therefore, it is important to identify drivers of the fluctuation of energy intensity. We use input–output structural decomposition analysis to investigate the contributions of changes in energy mix, sectoral energy efficiency, production structure, final demand stru...

The increasing penetration of renewable sources in electricity grids has motivated interest in controlling loads to compensate for variability of these generation sources. Air conditioners (ACs) are one type of loads that can be effectively controlled by broadcasting temperature setpoint offsets and using measurements of aggregate power demand for feedback, as shown in recent works. While such ...
