A frequency domain dynamic analysis is needed to obtain the response of structures constructed on a system of base isolators on flexible soil when subjected to earthquake ground motion. In such systems, the lateral stiffness of the base isolators is so small, compared to the structural stiffness, that in an earthquake attack the fundamental vibration mode dominates the response. With this in mi...

the long term goal attaining of economic system management requires the establishment of a dynamic framework to integrate multiple perspectives. this article considers the problem of economic development in macro level. as economic systems are complex adaptive systems composed of numerous numbers of components of dynamic and multidimensional nature, dynamics method is applied in this research. ...

this research has been designed in order to provide an appropriate methodology for business model change and update based on applying new information and communication technologies such as mobile technology in an organization. in this way, after investigation of all related references in the field of business model, ict change, business model change and applying mobile technology in organizatio...

In this study, liquid-liquid extraction process in a Kuhni extraction column was modeled and simulated. A non-equilibrium dynamic model was developed for modeling liquid-liquid extraction processes based on a rate-based model. The model equations are inclusive of partial and ordinary differential equations which were discretized in column height direction. The population balance model was used ...

In the study presented here, fuzzy logic was used to analyze behavior of a model economic dynamics that assumes income be in equilibrium when it is composed consumption and investment, is, savings investment are equal. The considered depend on previous period through uncertain factors, and, at same time, an magnitude across various periods, represented as number with known membership function. ...
