Construction of Families of Long Continued Fractions Revisited

In this survey article, we revisit construction of simple continued fractions of quadratic irrationals with long period lengths, which has generated much interest in the relatively recent literature. We show that new and not-sonew results actually follow from results of Perron in the 1950s and from results of this author from over a decade ago. Moreover, we are able to generalize and simplify n...

Electrical impedance for an electrolytic cell.

We analyze in which experimental conditions the concept of electrical impedance is useful for an electrolytic cell. The analysis is performed by solving numerically the differential equations governing the phenomenon of the redistribution of the ions in the presence of an external electric field and comparing the results with the ones obtained by solving the linear approximation of these equati...

Rock Masses as Construction Materials

A rock mass is a material quite different from other structural materials used in civil engineering. It is heterogeneous and quite often discontinuous, but is one of the materials in the earth's crust, which is most used in man's construction. Ideally, a rock mass is composed of a system of rock blocks and fragments separated by discontinuities forming a material in which all elements behave in...

Construction Methods and Building Materials

Today visitors often approach the massive pyramids, temples, and obelisks of the ancient Egyptians with wonder and disbelief. The huge blocks of stone used to create these architectural masterpieces were quarried and moved without the aid of modern technologies, and it is diffi cult for us to imagine how such feats of engineering could be accomplished without the aid of cranes, bulldozers, truc...
