Stabilization of the linearized water tank system

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 ...

Contained density currents with high volume of release

Mário Jorge Rodrigues Pereira Da Franca, Quentin Theiler

Contained density currents with high volume of release reflect against the boundaries of the reception environment commonly leading to oscillatory flow. These flows exist in sediment clarifiers, compromising their operations, and deposited signatures of co ...

Cyclic demand at the shell-bottom connection of unanchored steel tanks

Alain Nussbaumer, Gary Scott Prinz, Gustavo Cortes

Gasoline and other oil byproducts are commonly stored in steel tanks that rest on ground without any anchorage. Under strong motion, the impulsive mass of the contained liquid generates a moment about the base of the tank capable of causing partial uplift ...

On the low-cycle fatigue capacity of unanchored steel liquid storage tank shell-to-base connections

Alain Nussbaumer, Gary Scott Prinz

Under strong earthquake motions, the liquid stored within large unanchored steel tanks can cause rocking and uplift of the tank base from the supporting foundation. Repeated rocking can lead to low-cycle fatigue fractures in the tank base-plate, and ultima ...

Experimental Determination of the Capacity of Wall-to-Base Connections in Storage Tanks

Alain Nussbaumer, Gustavo Cortes, Eric Lattion

Earthquakes around the world have affected many unanchored tanks used for storage of gasoline. When these unanchored tanks are subjected to strong motion, the moment generated at the base, by the mass of liquid contained in the tank, will cause partial upl ...

Lightweight Modular Staging: A Pragmatic Approach to Runtime Code Generation and Compiled DSLs

Martin Odersky, Tiark Rompf

Software engineering demands generality and abstraction, performance demands specialization and concretization. Generative programming can provide both, but the effort required to develop high-quality program generators likely offsets their benefits, even ...

Modifier-Adaptation Methodology for Real-Time Optimization

Dominique Bonvin, Alejandro Gabriel Marchetti

The ability of a model-based real-time optimization scheme to converge to the plant optimum relies on the ability of the underlying process model to predict the plant's necessary conditions of optimality (NCO). These include the values and gradients of the ...

Sizing of a Supercapacitive Tank: Finite Elements Thermal Modelling

Alfred Rufer, Philippe Barrade

The sizing process of a supercapacitive tank is today a well-known procedure. It enables the identification of the number of cells needed to match energy requirements. In some cases, this number must be increased, in order to match the power needs of the a ...

Series Connection of Supercapacitors: Comparative Study of Solutions for the Active equalization of the Voltages

Philippe Barrade

Because of their low voltage level, supercapacitors need arrangement with series connection in order to obtain voltage levels from few dozen to few hunderd of volts. As for batteries, devices have then to be defined to balance the voltages across each seri ...
