A debate rages over imposing liability on manufacturers or users of insecure systems. Imposing either liability or fines on the creators or users of insecure systems may work, but how are buyers to distinguish? We propose a variety of signals and analyze them. We evaluate when signals may be preferable to liability as a mechanism for enhancing security.

The new Concrete Society Publication, Cementitious Materials, CSTR74, covers the effects of cementitious materials blast furnace slag (GGBS), fly ash (FA), limestone fines and silica fume (microsilica) on the properties of concrete. This paper focuses on the effects of silica fume on all the main properties of concrete in the fresh and hardened state as defined in the publication.

Systems are considered consisting of an arbitrary number of multiconductor transmission lines joined and terminated by arbitrary linear networks. The fines are assumed to be Iossy, with frequency-dependent parameters. The system is analyzed in the frequency domain, and the inverse Fourier transform is used to obtain tbe time-domain response.
