In non-cooperative bistatic synthetic aperture radar (SAR), the position of transmitter’s beam footprint should be detected and tracked in real-time to perform beam synchronization. Theoretical analysis shows that signal-tonoise ratio (SNR) of the reflected echoes from the observational scene is too low to apply the conventional detection and tracking method. According to the cross-correlation ...

We propose a system for user-aided image localization in urban regions by exploiting the inherent graph like structure of urban streets, buildings and intersections. In this graph the nodes represent buildings, intersections and roads. The edges represent “logical links” such as two buildings being next to each other, or a building being on a road. We generate this graph automatically for large...

This paper describes uncertainty quantification (UQ) of a complex system computational tool that supports policy-making for aviation environmental impact. The paper presents the methods needed to create a tool that is “UQ-enabled” with a particular focus on how to manage the complexity of long run times and massive input/output datasets. These methods include a process to quantify parameter unc...

Uncertainty quantification is essential for robotic perception, as overconfident or point estimators can lead to collisions and damages the environment robot. In this letter, we evaluate scalable approaches uncertainty in single-view supervised depth learning, specifically MC dropout deep ensembles. For dropout, particular, explore effect of at different levels architecture. We show that adding...

This paper presents the sensitivity and uncertainty analysis of a mathematical model for Greenhouse gas (GHG) and energy consumption assessment from wastewater treatment plants (WWTPs). The model is able to simultaneously describe the main biological and physical-chemical processes in a WWTP. Specifically, the mathematical model includes the main processes of the water and sludge lines influenc...

 All electricity generation technologies emit greenhouse gases at some point in their life cycle and hence have a carbon footprint.  Fossil-fuelled generation has a high carbon footprint, with most emissions produced during plant operation. “Carbon capture and storage” could reduce these significantly, though this is unproven at full scale.  Nuclear and renewable generation generally have a ...

Seismic acquisition footprint generally consists of modulations in recorded amplitudes that are spatially correlated to the surface locations of sources and receivers used in a survey. These amplitude variations obscure the true reflection response of the subsurface. In this study, synthetic seismic data were produced using numerical modelling code written in MATLAB. An “exhaustive” dataset was...
