Hickey and Wittenberg (Hickey and Wittenberg, 2004) study the “Two Tanks Problem”, a hybrid system described by Stursberg et al. (Stursberg et al., 1997). In this paper, we expand on the use of CLIP (Hickey, 2000) (a Constraint Logic Programming over Intervals and Functions language) to formally describe more complex systems. We add complexity in several forms. The simplest is to have a larger ...

in this paper the response modification factor due to ductility and saved strength of cylindrical concrete elevated and ground tanks is obtained using finite element method and nonlinear push over analysis considering the lateral effective modes of tanks. to modeling the behavior of the tank materials, the five parameters william-warnke and prefect elastoplastic models are used for concrete and...

In the modern world, government policy makers engage in the decision making process to pursue the interests of their countries. Think tanks play a significant role in this complicated process by giving advice to decision makers. Since the beginning of the twentieth century, think tanks increasingly emerged in the world, especially in Western European countries and the United States of America (...

Many liquid storage tanks around the world have affected by earthquakes. This structure can store dangerous chemical liquids. Hence dynamic behavior of ground supported rectangular storage tanks is very important due to their applications in industrial facilities. In current research, the seismic behavior of two water storage rectangular concrete tanks is examined. For this purpose, these tanks...

in this work, mathematical modeling of microbial(trichosporon sp.) biomass production in a stirred tankbioreactor and in an external airlift bioreactor has beeninvestigated. a model based on a tanks-in-seriesmodel without back-flow has been used to simulate theproduction of single cell protein in the external airliftbioreactor under an unsteady condition and withoutoxygen limitation, utilizing ...

A second order sliding mode control algorithm is presented for robust control of the liquid level in a pair of interconnected tanks. The controller is implemented on a laboratory rig. The implementation results show robustness to parameter variations such as tank area, the admittance coefficients of various pipes, leakage in the tanks and uncertainty in the pump dynamics. The potential of secon...

regarding the importance of the prevention of hazards and adverse environmental impacts in industrial and populated areas such as southern parts of tehran city, the response of impulsive period ground-supported tanks were assessed. having considered the study area's soil properties, the response of ground-supported tanks was modelled. regarding the soil properties of southern parts of tehran, t...
