Equilibrium strategies in a multiregional transboundary pollution differential game with spatially distributed controls [PDF]
Automatica, March 2021, 109411, 2019 We analyze a differential game with spatially distributed controls to study a multiregional transboundary pollution problem. The dynamics of the state variable (pollution stock) is defined by a two dimensional parabolic partial differential equation. The control variables (emissions) are spatially distributed variables. The model allows for a, possibly

Vegetation and Topographic Control on Spatial Variability of Soil Organic Carbon
Pedosphere, 2013 Abstract Soil organic carbon (SOC) is one of the most important parameters affecting the hydraulic characteristics of natural soils. Despite being rather easy to measure, SOC is known to be highly variable in space. In this study, vegetation, climate, and morphology factors were used to reproduce the spatial distribution of SOC in the mineral ...

Exact boundary controllability of the linear Biharmonic Schrödinger equation with variable coefficients [PDF]
arXiv, 2021 In this paper, we study the exact boundary controllability of the linear fourth-order Schr\"odinger equation, with variable physical parameters and clamped boundary conditions on a bounded interval. The control acts on the first spatial derivative at the left endpoint. We prove that this control system is exactly controllable at any time $T>0$.

Control-Oriented Modeling and Layer-to-Layer Spatial Control of Powder Bed Fusion Processes [PDF]
arXiv, 2023 Powder Bed Fusion (PBF) is an important Additive Manufacturing (AM) process that is seeing widespread utilization. However, due to inherent process variability, it is still very costly and time consuming to certify the process and the part. This has led researchers to conduct numerous studies in process modeling, in-situ monitoring and feedback control

Assessment of Temperature and Elevation Controls on Spatial Variability of Rainfall in Iran [PDF]
Atmosphere, 2017 With rainfall changes, hydrological process variability increases. This study predicts the potential effects of temperature and topography characteristics on rainfall spatial variability. Temperature and topography were considered as two effective factors that may influence monthly rainfall.

Managing Spatial and Temporal Variability in Irrigated Agriculture Through Adaptive Control [PDF]
Australian Journal of Multi-Disciplinary Engineering, 2009 Spatial variability in crop production occurs as a result of spatial and temporal variations in soil structure and fertility; soil physical, chemical and hydraulic properties; irrigation applications; pests and diseases; plant genetics; and local microclimate.
