Effect Of Surface

AbstractGlacier response to climate can be characterized by a single time-scale when the glacier changes sufficiently slowly. Then the derivative of volume with respect to area defines a thickness scale similar to that of Jóhannesson and others, and the time-scale follows from it. Our version of the time-scale is different from theirs because it explicitly includes the effect of surface elevation on mass-balance rate, which can cause a major increase in the time-scale or even lead to unstable response. The time constant has a dual role, controlling both the rate and magnitude of response to a given climate change. Data from South Cascade Glacier, Washington, U.S.A., illustrate the ideas, some of the difficulty in obtaining accurate values for the thickness and time-scales, and the susceptibility of all response models to potentially large errors.

Three Stages

The use of a dual-beam, delayed-sweep oscilloscope in the study of the ignition and discharge characteristics of an electronically ignited spark source is described. Transient electrical behavior on a micro and submicrosecond time scale during three stages of spark ignition is discussed, including the triggering and firing of the switching thyratron and the breakdown characteristics of the control spark gaps. Elimination of much of the time jitter in the ignition is discussed. A convenient and straightforward method of monitoring the oscillatory discharge current is presented and used to estimate the residual circuit inductance and resistance. Reactive models are suggested to explain the operation of the source.

The results of Nawrotzki (1962), Feigin (1979) and Puri (1982) show that the class of all point processes (on the real line) with the order statistic property consists of all mixed Poisson processes up to a time-scale transformation, and of all mixed sample processes. The present note characterizes those order statistic point processes that are mixed Poisson processes and mixed sample processes simultaneously.
