In this paper, a novel approach, called the Discrete-Time Occupancies Trajectory (DTOT), is proposed for intersection management of autonomous traffic in which all vehicles in the system are Autonomous Vehicles (AVs) and capable of wireless Vehicle-to-Intersection (V2I) communication. The main advantage of the proposed DTOT-based intersection manag...
Currently, the vortex cooling technology has gained wide attention as a new type of thrust chamber cooling method for liquid rocket engine in the world. Using tangential oxidant injection in the thrust chamber forms dual vortex structure thereby limits the combustion zone and avoids the sidewall temperature rise. The technology can effectively simp...
Numerical simulation of 3-D full-size model was conducted for 2 000 N gas hydrogen/gas oxygen vortex cooling thrust chamber. Velocity distribution characteristics of the flow field were obtained, and existence of the bidirectional vortex structure was verified. The interface of inner and outer vortexes accounted for 86% of the thrust chamber cylind...
In this paper, we present an optimization-based approach for safe, efficient, and resilient autonomous intersection traffic control in realistic vehicle-to-everything (V2X) communication environment. The proposed framework produces the fastest discrete-time trajectory for vehicles who want to cross an intersection. Constraints for safety are design...
Testing autonomous driving algorithms on real autonomous vehicles is extremely costly and many researchers and developers in the field cannot afford a real car and the corresponding sensors. Although several free and open-source autonomous driving stacks, such as Autoware and Apollo are available, choices of open-source simulators to use with them...

In this paper, we address the problem of safe and efficient intersection crossing traffic management of autonomous and connected ground traffic. Toward this objective, we propose an algorithm called the discrete-time occupancies trajectory based intersection traffic coordination algorithm (DICA). We show that the basic DICA has a computational comp...
This paper presents an optimization-based approach for safe and efficient intersection crossing traffic management under autonomous and connected ground traffic environment. The proposed algorithm, named MICA (Mixed integer programming based Intersection Coordination Algorithm), generates the fastest intersection crossing discrete-time trajectory f...
In this dissertation, we address a problem of safe and efficient intersection crossing traffic management of autonomous and connected ground traffic. Toward this objective, an algorithm that is called the Discrete-time occupancies trajectory based Intersection traffic Coordination Algorithm (DICA) is proposed. All vehicles in the system are Connect...
This paper proposes an intersection control algorithm which aims to determine an efficient vehicle-passing sequence that allows the emergency vehicle to cross an intersection as soon as possible while the travel times of other vehicles are minimally affected. When there are no emergency vehicles within the intersection area, the vehicles are contro...
