Sliding Mode Control in Aerospace Applications: A Survey
International Journal of Robust and Nonlinear Control, EarlyView.ABSTRACT Sliding mode control (SMC) enjoys robustness to matched and unmatched (in the case of minimum phase input‐output dynamics) bounded perturbations, and finite time convergence. Second‐order and higher‐order sliding mode control systems (2‐SMC/HOSMC) retain all the advantages of sliding mode control, but in addition can be applied to systems of ...

Meander‐Bend Erosion Dynamics Along a Gravel‐Bed River: Insights From Short‐Term UAV Monitoring
River Research and Applications, EarlyView.ABSTRACT Riverbank erosion is a natural process in meandering rivers that contributes to sediment supply and geomorphic diversity, yet it can threaten infrastructure and human activities within the floodplain. Recently, many studies have used high‐resolution remote sensing technologies to measure bank erosion, but they often focus on technical aspects ...

Sustainable Development, EarlyView.ABSTRACT This study examines the role of social capital in designing and implementing more effective governance strategies to improve the state of the Tagus River's significantly deteriorated middle reach (Spain). We employed social network analysis (SNA) to evaluate the bonding, bridging and linking social capital and the quality of stakeholder ...

Liouville solution in General Relativity with a scalar field
Physics Letters BNew one parameter family of exact solutions in General Relativity with a scalar field has been found. The metric is of Liouville type which admits complete separation of variables in the geodesic Hamilton–Jacobi equation.

Hurricane‐induced risk contagion in commercial real estate: Evidence from Hurricane Sandy
Real Estate Economics, EarlyView.Abstract This study examines how hurricane‐induced destruction affects the prices of nearby undamaged commercial real estate properties, using Hurricane Sandy as a natural experiment. Using Real Capital Analytics transaction records spatially merged with Federal Emergency Management Agency building‐level damage data, we empirically employ a difference ...

Homogeneous and two-step homogeneous geodesics in homogeneous spaces
, 2018 The subject of the present thesis is the study of geodesic curves in homogeneous spaces. The problem of determining the form of the geodesic curves in a pseudo-Riemannian manifold is an interesting and in general hard one, and usually reduces to either ...

The existence of light‐like homogeneous geodesics in homogeneous Lorentzian manifolds [PDF]
Mathematische Nachrichten, 2015 In previous papers, a fundamental affine method for studying homogeneous geodesics was developed. Using this method and elementary differential topology it was proved that any homogeneous affine manifold and in particular any homogeneous pseudo‐Riemannian manifold admits a homogeneous geodesic through arbitrary point.

A tutorial on Bayesian model averaging for exponential random graph models
British Journal of Mathematical and Statistical Psychology, EarlyView.Abstract The use of exponential random graph models (ERGMs) is becoming prevalent in psychology due to their ability to explain and predict the formation of edges between vertices in a network. Valid inference with ERGMs requires correctly specifying endogenous and exogenous effects as network statistics, guided by theory, to represent the network ...

Homogeneous geodesics of non-reductive homogeneous pseudo-Riemannian 4-manifolds
, 2015 After obtaining an explicit description in global coordinates of invariant metrics on four-dimensional non-reductive homogeneous pseudo-Riemannian manifolds, for each of these spaces we completely describe Killing and geodesic vector elds and ...
