Sliding Mode Control in Aerospace Applications: A Survey

open access: yesInternational 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 ...

Reasoning Together or Clicking Through? Analyzing Patterns of Group Science Talk On and Off Individualized Computers

open access: yesScience Education, EarlyView.
ABSTRACT In this article, I examine group science talk within the classrooms of three urban secondary science teachers who regularly use one‐to‐one computers to mediate their NGSS‐aligned science instruction. I combine methods of framing analysis (Goffman 1974; Tannen 1993) and interaction analysis (Jordan and Henderson 1995) to illustrate differences ...

Facing Obsolescence: Component Repair and Collaboration in the Independent ICT Commercial Repair Sector

open access: yesSustainable Development, EarlyView.
ABSTRACT Repairs are becoming more difficult to perform due to multiple factors, including obsolescence, complexity of designs, technological change and lack of information and spare parts. This underlines a conflict between repair and technological designs driven by accumulation logics that require increasing growth rates.

Financial Inclusion for Smallholders: Integrating a Resource Nexus Approach Into Agricultural Finance Systems

open access: yesSustainable Development, EarlyView.
ABSTRACT Smallholder farmers remain structurally excluded from the current agricultural finance system. Existing research in this area examines financial inclusion through fragmented environmental, social, and economic lenses, limiting system‐level understanding.

Electrification and Child Work: Direct and Spillover Effects in Ethiopia

open access: yesSustainable Development, EarlyView.
ABSTRACT While electrification is often promoted for improving adults' labor supply, its effect on child work remains underexplored. Using four waves of Ethiopian panel data, we examine how electrification affects children's work time. By differentiating between households with and without own electricity access within electrified communities, we ...
