Laterally unconfined neutral or negative buoyancy inflow into a quiescent ambient over sloping bottom

This work studies the nearshore hydrodynamics of a shallow turbulent flow entering a laterally unconfined quiescent ambient with a sloping bottom boundary. Examples of such flow are neutrally buoyant ebb tidal jets and hyperpycnal river plumes entering ope ...

Citizen Think Tanks: co-designing post-pandemic housing futures

Claudia Rebeca Binder Signer, Anna Pagani, Valentin Daniel Maurice Bourdon, Livia Bianca Fritz

During the first wave of COVID-19, Swiss residents found themselves spending most of their time in homes unable to accommodate the needs hitherto met by cities. While scholars and practitioners have proposed strategies to mitigate the effects of housing de ...

Stabilization of the linearized water tank system

Shengquan Xiang

In this article we study the so-called water tank system. In this system, the behavior of water contained in a 1-D tank is modelled by Saint-Venant equations, with a scalar distributed control. It is well-known that the linearized systems around uniform st ...

Uplift mechanics of unanchored liquid storage tanks subjected to lateral earthquake loading

Konstantinos Bakalis

Motivated by the seismic response of unanchored liquid storage tanks, their uplift mechanism under strong lateral loading is examined. Using three-dimensional finite element models, nonlinear static analysis is conducted to define the moment-rotation relat ...
