DAMAGE AND PLASTICITY CONSTANTS OF CONVENTIONAL AND HIGH-STRENGTH CONCRETE PART II: STATISTICAL EQUATION DEVELOPMENT USING GENETIC PROGRAMMING

Several researchers have proved that the constitutive models of concrete based on combination of continuum damage and plasticity theories are able to reproduce the major aspects of concrete behavior. A problem of such damage-plasticity models is associated with the material constants which are needed to be determined before using the model. These constants are in fact the connectors of constitu...

A Mathematical Theory of Generalization: Part II

A b st r a ct. The problem of how best to generalize from a given learning set of input-output examples is cent ral to the fields of neur al nets, statistics, approximation theory, and artificial intelligence. This series of pap ers inve stigates this problem from within an abst ract and mod elindepend ent fr amework and then test s some of the resultant concept s in real-world situations. In t...

Learning and memory, part II: molecular mechanisms of synaptic plasticity.

Learning and Memory, Part I, described how shortterm memories are consolidated into long-term memories and the brain regions involved in this process. As previously discussed, the hippocampus is required for the formation of declarative memories (conscious memories of events and facts). This type of memory was destroyed in the famous clinical case of H.M. after he sustained a bilateral hippocam...

Preparation of the Phencyclidine Analogues (Part II)

Using a-tetralone, as starting material, a series of phencyclidine analogues were synthesized. This ketone was reacted separately with ethylmagnesium bromide, P-methoxyphenylmagnesium bromide and P-methylphenylmagnesium bromide. The resultant alcohols were treated with a suspension of NaN3 and CCl3COOH in CHCl3. The azides were subsequently...
