Stability Criteria of Reversible Pump Turbines

, 2014
The objective in this Master's Thesis was to verify the stability criteria for a centrifugal pump. Operation of an unstable pump may lead to either exponential or oscillatory unstable behavior of both pressure and volume flow of the water in the conduit system. This is of course unwanted, and fulfilling the stability criteria is desirable.

Tinkering Towards Sustainability: Bundling Innovations to Electrify the Fossil‐Dependent Process Industry

Creativity and Innovation Management, Volume 35, Issue 2, Page 356-373, June 2026.
ABSTRACT Sustainability transitions, such as electrifying the process industry, require a bundle of related innovations to make meaningful progress. Drawing on literature on innovation through tinkering, that is, adaptive, typically small‐scale experimentation with various forms of innovation, and applying a micropolitical perspective, this qualitative
