✦ Synopsis

The authors' previously presented model determines the time to breakage of window glass exposed to a compartment fire. The physical and mechanical properties of glass and the history of the compartment fire are required. Among the mechanical properties of glass, the breaking stress, o'b, is the least well known. Here, experiments on 59 plate glass samples using the four-point flexure method are described to determine the breaking stress distribution. This distribution is described by a three-parameter cumulative Weibull function, G(O'b)=0, for O'h < 0". and G(trh)=l--exp(tYh--tr") m for trb>-tr,,

Window glass breaking plays an important role in compartment fire dynamics as the window acts as a wall before breaking and as a vent after breaking. Previous work suggested a model for the time to breakage of a window glass exposed to a particular fire. In this paper, the glass thermal fields obtai

The spectral noise intensity of the drain current of an n-channel (100) Si-MOSFET in strong inversion was measured as a function of drain current and gate voltage at T = 4.2 K, In addition to flicker noise and white noise it was possible to distinguish a Lorentzian, which was due to generation-recom
