    Architecture as Stage
    Li, Tao (Virginia Tech, 2015-02-03)
    Theaters used to an important civic space, and nowadays urban spaces have begun to be viewed as theatrical spaces. Theaters as well as cinemas are primarily shared spaces. As online viewing of films has become more prevalent, it is pertinent to explore how a shared experience can be enhanced. An outdoor theater where neighbors could gain access by foot, an atrium where preview viewing, discussion and gallery viewing could happen concurrently, are a few examples of what this multiplex offers. The multiplex is located at Van Ness Metro Station facing Connecticut Ave in Washington D.C. The Multiplex comprises eleven movie theaters with seating capacity ranging from 35 to 150, an outdoor theater, a restaurant and several roof terraces.

    General Aviation Demand Forecasting Models and a Microscopic North Atlantic Air Traffic Simulation Model
    Li, Tao (Virginia Tech, 2015-01-06)
    This thesis is focused on two topics. The first topic is the General Aviation (GA) demand forecasting models. The contributions to this topic are three fold: 1) we calibrated an econometric model to investigate the impact of fuel price on the utilization rate of GA piston engine aircraft, 2) we adopted a logistic model to identify the relationship between fuel price and an aircraft's probability of staying active, and 3) we developed an econometric model to forecast the airport-level itinerant and local GA operations. Our calibration results are compared with those reported in literature. Demand forecasts are made with these models and compared with those prepared by the Federal Aviation Administration. The second topic is to model the air traffic in the Organized Track System (OTS) over the North Atlantic. We developed a discrete-time event model to simulate the air traffic that uses the OTS. We proposed four new operational procedures to improve the flight operations for the OTS. Two procedures aim to improve the OTS assignments in the OTS entry area, and the other two aim to benefit flights once they are inside the OTS. The four procedures are implemented with the simulation model and their benefits are analyzed. Several implementation issues are discussed and recommendations are given.
