Water Demand Maximization: Quick Recovery of Nonlinear Physics Solutions
Sai Krishna Kanth Hari, Russell Bent
Determining the maximum demand a water distribution network can satisfy is crucial for ensuring reliable supply and planning network expansion. This problem, typically formulated a…
Optimization of District Heating Network Parameters in Steady-State Operation
Sai Krishna K. Hari, Anatoly Zlotnik, Shriram Srinivasan +2
We examine the modeling, simulation, and optimization of district heating systems, which are widely used for thermal transport using steam or hot water as a carrier. We propose a g…
Joint Expansion Planning of Power and Water Distribution Networks
Sai Krishna Kanth Hari, Ahmed Zamzam, Byron Tasseff +2
This research explores the joint expansion planning of power and water distribution networks, which exhibit interdependence at various levels. We specifically focus on the dependen…
Relaxations of the Steady Optimal Gas Flow Problem for a Non-Ideal Gas
Sai Krishna Kanth Hari, Kaarthik Sundar, Shriram Srinivasan +1
Natural gas ranks second in consumption among primary energy sources in the United States. The majority of production sites are in remote locations, hence natural gas needs to be t…
Cooperative Coverage with a Leader and a Wingmate in Communication-Constrained Environments
Sai Krishna Kanth Hari, Sivakumar Rathinam, Swaroop Darbha +1
We consider a mission framework in which two unmanned vehicles (UVs), a leader and a wingmate, are required to provide cooperative coverage of an environment while being within a s…
Bounds on Optimal Revisit Times in Persistent Monitoring Missions with a Distinct \& Remote Service Station
Sai Krishna Kanth Hari, Sivakumar Rathinam, Swaroop Darbha +3
Persistent monitoring missions require an up-to-date knowledge of the changing state of the underlying environment. UAVs can be gainfully employed to continually visit a set of tar…
Operation of Natural Gas Pipeline Networks With Storage Under Transient Flow Conditions
Sai Krishna Kanth Hari, Kaarthik Sundar, Shriram Srinivasan +2
We formulate a nonlinear optimal control problem for intra-day operation of a natural gas pipeline network that includes storage reservoirs. The dynamics of compressible gas flow t…
An Approximation Algorithm for a Task Allocation, Sequencing and Scheduling Problem involving a Human-Robot Team
Sai Krishna Hari, Abhishek Nayak, Sivakumar Rathinam
This article presents an approximation algorithm for a task allocation, sequencing and scheduling problem involving a team of human operators and robots. Specifically, we present a…
Persistent Monitoring of Dynamically Changing Environments Using an Unmanned Vehicle
Sai Krishna Kanth Hari, Sivakumar Rathinam, Swaroop Darbha +3
We consider the problem of planning a closed walk for a UAV to persistently monitor a finite number of stationary targets with equal priorities and dynamically changin…
Spontaneous CP Violation and the Strong CP Problem in Left-Right Symmetric Theories
Sebastian Ohmer
We study spontaneous CP violation as a solution to the strong CP problem in left-right symmetric theories. The discrete CP symmetry is broken by a complex vacuum expectation value…
Hierarchical Predictive Control Algorithms for Optimal Design and Operation of Microgrids
Sai Krishna Kanth Hari, Kaarthik Sundar, Harsha Nagarajan +2
In recent years, microgrids, i.e., disconnected distribution systems, have received increasing interest from power system utilities to support the economic and resiliency posture o…
