Effect of Resonant Mixer Granulation Parameters on Prill Properties
Propellants, Explosives, Pyrotechnics, EarlyView.ABSTRACT Resonant mixing is a promising processing approach to manage mixing of materials with high solids content and has shown strong performance for mixing powders and pastes in energetic materials. This has led to the exploration of the approach for granulation of primary particles into millimeter‐sized agglomerates, including for generating ...

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 ...

Sustainable Development, EarlyView.ABSTRACT Farmers' capabilities, a core component of social sustainability, have been largely neglected in sustainable agriculture discourse. Using a relational approach to capabilities and autonomy, this study explores how women farmers translate the opportunity of agricultural innovation into their valued outcomes, and which factors shape their ...

National Policy Coherence Counts for Reducing Inequality in Global Climate and Development Agendas
Sustainable Development, EarlyView.ABSTRACT International institutions promote policy coherence as crucial to the effective and fair implementation of global sustainability agendas, though the evidence for its benefits is slim. We present here the first systematic cross‐country dataset on the consequences of national government efforts to promote policy coherence for vulnerable groups ...

Resource redeployment as an entry advantage in resource‐poor settings
Strategic Management Journal, EarlyView.Abstract Research Summary Scarcity of productive factors poses a challenge for firms entering underdeveloped regions. We theorize that incumbent firms can overcome scarcity of skilled human capital in local labor markets by redeploying workers from existing units.
