In this paper, experimental responses of the clamped mild steel, copper, and aluminium circular plates are presented subjected to blast loading. The GMDH-type neural networks (Group Method of Data Handling) are then used for the modelling of the mid-point deflection thickness ratio of the circular plates using those experimental results. The aim of such modelling is to show how the mid-point de...

Physical models, like mathematical models, are useful tools in biomechanical research. Physical models enable investigators to explore parameter space in a way that is not possible using a comparative approach with living organisms: parameters can be varied one at a time to measure the performance consequences of each, while values and combinations not found in nature can be tested. Experiments...

Three steps in data modelling include conceptual, logical and physical modelling. The conceptual modelling models data from the users’ perspective independently from any logical and physical implementation. The paper discusses different conceptual modelling styles that may apply in modelling transactional and analytical information system. They are distinguished by the modelling intention, the ...
