Fare Design in Urban Transit Network considering Elastic Demand and Adverse Weather’s Impact
Published 2014-01-01“…Such transit fare design problem is described through bilevel programming, in which the upper level is the transportation authority’s transit fare structure decision aiming to minimize the transit network’s total travel and operation cost, while the lower level is a transit network assignment model considering supply and demand uncertainties that influence passengers’ travel choice decisions. A heuristic algorithm is developed to solve the problem, and a numerical example is presented to illustrate the application. …”

Application of Machine Learning in Multi-Directional Model to Follow Solar Energy Using Photo Sensor Matrix
Published 2022-01-01“…According to the findings, the DNN is capable of making more accurate and reliable predictions of the incoming solar irradiance than the persistent algorithm. This is the case across the board. Even without any actual data, the proposed model is considered to be state-of-the-art because it outperforms the current NWP forecasts for the same time horizon as those forecasts. …”
