This paper proposes a novel theory, coined as Topological Tail Dependence Theory, that links the mathematical theory behind Persistent Homology (PH) and the financial stock market theory. This study also proposes a novel algorithm to measure topological stock market changes as well as the incorporation …

While modern wind turbines have become by far the largest rotating machines on Earth with further upscaling planned for the future, a renewed interest in small wind turbines (SWTs) is fostering energy transition and smart grid development. Small machines have traditionally not received the same level …

The dynamic inflow effect describes the unsteady aerodynamic response to fast changes in rotor loading due to the inertia of the wake. Fast changes in turbine loading due to pitch actuation or rotor speed transients lead to load overshoots. The phenomenon is suspected to be also relevant for gust situations; …

The real estate market is a turbulent market where multiple trends and developments continuously affect real estate prices. Developments such as the COVID-19 pandemic and the growing E-Commerce market share caused an uncertainty in the high street real estate market. The average risk premium of Gross …

Prof. dr. Monica den Boer sprak haar oratie uit ter aanvaarding van haar Leerstoel Militaire Politie Operaties (MPO) bij de vakgroep Krijgswetenschappen. Zij ontvouwde in When Peace falls to Pieces: Prospects for Military Policing in Turbulent Times hoe de oorlog in Oekraïne een serie nieuwe dreigingen …

Sustainability transition research seeks to understand the patterns and dynamics of structural societal change as well as unearth strategies for governance. However, existing frameworks emphasize innovation and build-up over exnovation and break-down. This limits their potential in making sense of the …

Purpose. Psychological contracts (PC) capture employees’ mental schema of the exchange agreement between themselves and their organizations, through which they make sense of their daily work environment (Rousseau, 2001). PCs are not only influenced by (large) organizational changes (Freese et al., 2011), …

We investigate the relationship between firm performance and patterns of exploration and exploitation dynamics under conditions of environmental turbulence. Adopting a contingency perspective, we develop arguments on how environmental turbulence moderates the effects of the simultaneous or sequential …

Over the past year and a half, the pandemic has posed serious challenges to many professions, including education in general and teacher education in particular. COVID19 created an unprecedented and unimagined disruption without preparation. As in schools, in teacher education daily routines were challenged …

In this presentation a new EA Wind Task is presented, i.e. an international cooperative project on the field of aerodynamic wind turbine measurements organised under auspices of the IEA
