Optimal three-dimensional biped walking pattern generation based on geodesics
International Journal of Advanced Robotic Systems, 2017 The innovative three-dimensional humanoid biped gait planning method using geodesics is introduced in this article. In order to control three-dimensional walking, the three-dimensional linear inverted pendulum model is studied in our energy-optimal gait ...

Rent affordability after hurricanes: Longitudinal evidence from US coastal states
Risk Analysis, EarlyView., 2023 Abstract Climate change is expected to increase the frequency and intensity of natural hazards such as hurricanes. With a severe shortage of affordable housing in the United States, renters may be uniquely vulnerable to disaster‐related housing disruptions due to increased hazard exposure, physical vulnerability of structures, and socioeconomic ...

Reference Tracking and Disturbance Rejection for Nonlinear Systems Using LPV Control
International Journal of Robust and Nonlinear Control, EarlyView.ABSTRACT The Linear Parameter‐Varying (LPV) framework has been introduced with the intention to provide stability and performance guarantees for analysis and controller synthesis for Nonlinear (NL) systems through convex methods. By extending results of the Linear Time‐Invariant framework, mainly based on quadratic stability and performance using ...

Inscribing geodesic circles on the face of the superstratum
Journal of High Energy PhysicsWe use families of circular null geodesics as probes of a family of microstate geometries, known as (1, 0, n) superstrata. These geometries carry a left-moving momentum wave and the behavior of some of the geodesic probes is very sensitive to this ...

The extent and drivers of internal agglomeration of U.S. multi‐unit firms
Strategic Management Journal, EarlyView.Abstract Research Summary This paper examines the extent and determinants of internal agglomeration—the spatial clustering of establishments within firms. It introduces a novel methodology that benchmarks a firm's spatial footprint against that of comparable stand‐alone firms, yielding a firm‐level measure of internal agglomeration.

Concentration in cross‐border research collaborations and MNCs' knowledge creation in a host country
Strategic Management Journal, EarlyView.Abstract Research Summary This study elucidates the previously underexplored structural heterogeneity inherent in multinational corporations' (MNCs) internal linkages by examining the concentration of cross‐border collaborations among inventors within host countries.
