| Dr. Deborah Goodings | The Geotechnics of Extreme Heat in the Context of Tunnel Fires
A tunnel fire can cause severe damage to the structural lining of a tunnel, but little is known about the response of the soil surrounding the tunnel, soil that the tunnel’s integrity depends upon for support. This research is examining temperature gradients and water pressures that develop in saturated and unsaturated soils subjected to intense heat gradients.  Detonation of landmine Detonation of landmines is an issue both in war and in peace. This research has explored stresses generated in soil by vehicles passing on the soil surface to examine when mines might be detonated and when they might not. Sustainable engineering with Bamboo Bamboo is the world’s fastest growing building material, and is used in some countries in construction. This research, presently in the very earliest stages, will explore its uses in structural engineering for reinforcement, and in geotechnical engineering for soil improvement, focusing on developing dependable engineering design guidelines for its use. |

| Dr. Dimitrios G. Goulias | High Performance Concrete Pavements (sponsors, MSHA, FHWA, Concrete Industry) The objective of the study was to examine the benefits of using innovative pavement concrete mixtures for enhancing the flexural fatigue resistance and improving the shrinkage behavior of concrete pavement mixtures. New technology Based Approach to Advance Higher Volume Fly Ash Concrete with Acceptable Performance This project will address the two major stumbling blocks, lower early-age strengths (less than 7 days) and delayed initial setting times, which prevent the large scale utilization of HVFA concrete. Evaluation of Aggregate for Masonry Mortar: Aggregate Characteristics and Impact on Mortar Properties This project would look at sand gradation and its effect on the physical properties of mortar, such as compressive strength, air content, flow, and water retention. |

| Dr. Charles Schwartz | Use of Radio Frequency Identification (RFID) Tags in Hot Mix Asphalt Inexpensive expendable radio frequency identification (RFID) technology will be used to spatially locate shipments of hot mix asphalt concrete during pavement construction. Calibration of Rutting Models for HMA Structural and Mix Design This project will enhance the hot-mix asphalt rutting prediction model in the new national mechanistic-empirical pavement design methodology developed in NCHRP Project 1-37A. Implementation of the NCHRP 1-37A Design Guide A major proposed revision to the AASHTO Pavement Design Guide has recently been developed. This new Guide is expected to replace the current empirical design procedures based on road tests from the late 1950s with a state-of-the-art mechanistic-empirical design procedure that more rationally incorporates modern material types and characterization, traffic levels, and construction practices. |

| Dr. Steven A. Gabriel | Market equilibrium models of natural gas markets in North America and Europe The models are based on a Nash-Cournot game theory concept in which market players such as gas producers, traders, or pipelines are individually modeled as solving certain profit maximization optimization problems |
|
| Multiobjective optimization and statistical modeling for management of wastewater treatment processes The objective is to develop multiobjective optimization and statistical models to understand and analyze the tradeoffs of biosolids odors versus costs from a processing and distributional perspective. |
||
| Complementarity Models for Electric Power Market Equilibria The models additionally take into account that the market operator enforces a minimum profit condition. Several algorithms have been proposed for solution of this electric power planning problem. |
||
| Optimization Models for Electric Power Retailers The objective is to build simulation and optimization models to guide electric power retailers in their load forecasting and risk management programs and contracts with both suppliers and end-users. |

| Dr. M. Sherif Aggour | Management of Montgomery County Parking Garages The research will establish a data base that will include a visual condition assessment of the 18 garages in the County. This will be followed by a nondestructive evaluation of the garages from which a performance model will be determined that will provide information on the rate of deterioration of the garages and, hence, a prediction on where the garages are in their life cycles. |

| Dr. Ali Haghani | Dynamic Decision Making for Less-Than-Truckload Trucking Operations The research focused on trucking operations of less-than-truckload (LTL) trucking companies. It attempts to use real-time information in decision making for LTL carriers in the dynamic environment. Container Ship Stowage Planning with Quay Crane Utilization This research deals with the containership stowage planning problem which is the problem of stacking containers on different bays of a containership that visits several ports during a voyage. The proposed optimization framework takes into account the stability of the vessel, operational constraints and utilization of quay carnes. Existing Right-of-way Plats Database GIS Applications The objective of this research project was to develop a prototype automated computerized system to perform queries on an existing right-of-way plat database for Office of Real Estate at Maryland State Highway Administration. Optimal Scheduling of Evacuation Operations An optimization model for Emergency Evacuation Planning is proposed in this research along with a simulation-optimization framework to solve for the system optimal evacuation plan. The model simultaneously solves for the choice of destination, evacuation route, and departure time for all evacuees from given origins. |
