Transient electromagnetic response of a permeable and conductingground to a linear current ramp switch-off

The asymptotic representation for late times of the transient electric field above and on a uniform permeable and conducting ground is derived with the hitherto untreated effects of a ramp switch-off source current. The source is a vertically oriented finite loop placed on the ground. Certain response functions are defined and the results are compared directly to those of a Heaviside switch-off. The authors show that the ramp-time dependence is given by certain well-defined functions multiplying the respective terms of the series for the field produced by a Heaviside switch-off source. They also show that for late times t , the first term shows an enhancement of the ramp switch-off field relative to the Heaviside of the order of 1+5t₀/4t, where t₀ is the ramp time     

Derivation of Glue Code for Agent Interoperation

Getting agents to communicate requires translating the data structures of the sender (the source representation) to the format required by the receiver (the target representation). Assuming that there is a formal theory of the semantics of the two formats, which explains both their meanings in terms of a neutral topic domain, we can cast the translation problem as solving higher-order functional equations. Some simple rules and strategies apparently suffice to solve these equations automatically. The strategies may be summarized as: decompose complex expressions, replacing topic-domain expressions with source-domain expressions when necessary. A crucial issue is getting the required formal theories of the source and target domains. We believe it is sufficient to find partial formalizations that grow as necessary.
