Passive casing treatments for stall margin improvement in axial compressors
, 2020 Axial flow compressors are mainly used in the power generation and aerospace industry. Axial compressors are prone to instability issues since it is the nature of compressors to impart work on a fluid across an adverse pressure gradient. Instability in the compressor will instigate rotating stall and ultimately surge within the compression system.

Brexit and Its Impact on EU Financial Markets
International Journal of Finance &Economics, EarlyView.ABSTRACT We investigate the impact of Brexit on volatility spillovers across the EU countries. We introduce a Brexit intensity measure that assigns an intensity score reflective of the financial markets' reaction to the events that occurred as Brexit negotiations began to unfold.

Public Administration and Development, EarlyView.ABSTRACT Policy robustness, that is, the capacity of policies to sustain performance across diverse and uncertain futures, is increasingly considered a core objective of public policymaking. Although adaptive policymaking is widely promoted as an approach to achieving policy robustness, it suffers from a central paradox highlighted by theories of the ...
