Pump turbines in existing powerplants

, 2019
En brukervennlig metode for å designe kontraroterende aksialpumper har blitt utviklet ved bruk av Matlab. Grafiske brukergrensesnitt har blitt laget for å skrive inn designparametre og å vise designresultater. Designmetoden benytter seg av eksisterende løftelinjeteori for design og optimalisering av kontraroterende propeller, men den er modifisert for ...

A new organizational structure database: Examining structure through top management team compositions

Strategic Management Journal, EarlyView.
Abstract Research Summary Studies using archival organizational structure data are not as prevalent as one might expect for such a critical strategy topic. We seek to facilitate more studies in this domain by introducing a novel, hand‐collected dataset of top management team compositions of S&P 500 firms between 1993 and 2020.
