  • Explosion of millimeter-wave (mm-wave) bandwidth opens up applications in 5G wireless systems spanning communications, localization, imaging, and radar. This project addresses challenges in mathematics, engineering, and science in developing efficient wideband beamformers based on sparse factorizations of the matrix called-delay Vandermonde matrices (DVM). The proposed highly integrated approach is attractive for mobile applications including 5G smart devices, the internet of things, mobile robotics, unmanned aerial vehicles, and other emerging applications focused on mm-waves.

Composite Wind Turbine Blade

  • PI Sathya Gangadharan

  • The world's primary energy needs are projected to grow by 56% between 2005 and 2030, by an average annual rate of 1.8% per year (International Energy Agency, 2012). Energy policy has confirmed the improvement of the environment sustainability of energy as a primary objective also though increasing use of renewable sources (Increasing Wind Energy's contribution to U.S. Electricity supply, 2008).

  • The accuracy of the simulation of gas turbine component temperatures relies heavily on the selection of appropriate modeling parameters.  The focus of this project is the research and development of these parameters, through the comparison to experimental data-sets. 

Computational Optimization & Experimental Validation of Gas Turbine Cooling Configurations

  • PI Mark Ricklick

  • Optimization techniques have recently matured to the point that they can be routinely utilized in the design process, particularly when coupled with Computer Aided Engineering tools. With respect to gas turbine cooling design methods, optimization tools allow the engineer to develop configurations which promote high levels of heat removal, while minimizing parasitic losses.
Cost Optimization Modeling for Airport Capacity Expansion Problems in Metropolitan Areas

  • PI Woo Jin Choi

    CO-I Dothang Truong

  • The purpose of this research was to develop a cost optimization model to identify an optimal solution to expand airport capacity in metropolitan areas in consideration of demand uncertainties. The study first analyzed four airport capacity expansion cases from different regions of the world to identify possible solutions to expand airport capacity and key cost functions which are highly related to airport capacity problems. Using mixedinteger nonlinear programming (MINLP), a deterministic optimization model was developed with the inclusion of six cost functions: capital cost, operation cost, delay cost, noise cost, operation readiness, and airport transfer (ORAT) cost, and passenger access cost. These six cost functions can be used to consider a possible trade-off between airport capacity and congestion and address multiple stakeholders’ cost concerns.
