The Dynamics of the Policy Mix and Sectoral Gaps in South Korea's Decarbonization Transition
Environmental Policy and Governance, EarlyView.ABSTRACT While a coherent policy mix is a fundamental prerequisite for successful energy transitions, existing frameworks predominantly rely on static evaluations. This horizontal approach fails to capture the deep temporal dynamics and physical inertia inherent in socio‐technical regime shifts.

Learning as Compost: Reorienting Evaluation in an Era of Authoritarian Drift
New Directions for Evaluation, EarlyView.ABSTRACT We synthesize insights from seven cases to interrogate a central assumption of the learning function of evaluation: Learning can be strengthened through better design, integration, or alignment with accountability systems. Taking the issue's conceptual framework seriously, the essay reflects what the cases reveal about the nature of learning ...

Mid-span stall inception in a transonic fan
, 2020 In this paper, steady and unsteady CFD have been used to investigate stall inception for a modern low pressure ratio transonic fan. The computational results are validated against measurement data from a high-speed test facility.

Notes on research into some aspects of stall-warning devices [PDF]
, 1953 The problems of detecting and indicating an approaching stall have been investigated in flight on an “Anson” aircraft. A lower-surface flap near the leading-edge of the wing detects the approaching stall at a speed which depends critically on the length ...

Local Nonlinear Control of Stall Inception in Axial Flow Compressors
, 1993 A combination of theoretical and computational nonlinear analysis techniques are used to study the scenario of bifurcations responsible for the initiation of rotating stall in an axial flow compressor model.
