Partitioning and Observability in Linear Systems via Submodular Optimization
Mohamad H. Kazma, Ahmad F. Taha
Network partitioning has gained recent attention as a pathway to enable decentralized operation and control in large-scale systems. This paper addresses the interplay between parti…
Exploring Uncertainty Propagation in Coupled Hydrologic and Hydrodynamic Systems via Distribution-Agnostic State Space Analysis
Mohamad H. Kazma, Ahmad F. Taha
Accurate overland runoff and infiltration predictions are critical for effective water resources management, in particular for urban flood management. However, the inherent uncerta…
Revisiting The PBH Test: Fast Uncontrollability Certificates via Krylov Methods
Ahmad F. Taha, Mohamad H. Kazma, Abdallah A. Albustami
This letter revisits the classical PBH test through the lens of finite-horizon reachability. By casting state transfer as a minimum energy, primal optimization problem, we show tha…
Nonsmooth Hydraulics, Smooth Control: System Theory Framework for Analyzing Water Networks
Ahmad F. Taha, Mohamad H. Kazma
This paper presents a comprehensive control-theoretic analysis of water distribution network (WDN) hydraulics. Starting from a general nonlinear differential algebraic equation (DA…
Connections Between Determinantal Point Processes and Gramians in Control
Mohamad H. Kazma, Ahmad F. Taha
Determinantal point processes (DPPs) are probability models over subsets of a ground set that favor diverse selections while suppressing redundancy. That is, they tend to assign hi…
Verification and Forward Invariance of Control Barrier Functions for Differential-Algebraic Systems
Hongchao Zhang, Mohamad H. Kazma, Meiyi Ma +2
Differential-algebraic equations (DAEs) arise in power networks, chemical processes, and multibody systems, where algebraic constraints encode physical conservation laws. The safet…
