31. A computational model is one which can be mathematically analyzed, tested and simulated using computer systems. 32. This interest culminated in the publication in 2001 of a book on computational models of consciousness. 33. A computational model of the Purkinje cell has shown intracellular calcium computations to be responsible for toggling. 34. Heterogeneous database systems ( HDBs ) are computational models and software implementations that provide heterogeneous database integration. 35. The technology behind prescriptive analytics synergistically combines hybrid data, business rules with mathematical models and computational models . 36. In order to create better computational models of language, an understanding of language s structure is crucial. 37. The computational model is presented below where: 38. This community embraces the synergy of experimental, theoretical and computational models to advance the technology and science. 39. In addition to the general computational models , some simpler computational models are useful for special, restricted applications. 40.
