Boundary crossing probabilities for the cumulative sample mean
Abstract
We develop a new measure of reliability for the mean behavior of a process by calculating the probability the cumulative sample mean will stay within a given distance from the true mean over a period of time. This probability is derived using boundary-crossing properties of Brownian bridges. We derive finite sample results for independent and identically dis- tributed normal data, limiting results for data meeting a functional central limit theorem, and draw parallels to standard normal confidence intervals. We deliver numerical results for i.i.d., dependent, and queueing processes.

Dynamic Characteristics of Liquid Motion in Partially Filled tanks of Spinning Spacecraft
Agrawal, B.N. (1990);This paper presents a boundary layer model to predict dynamic characteristics of liquid motion in partially filled tanks of a spinning spacecraft. The solution is obtained by solving three boundary value problems: inviscid, ... -
Cooperative Control of Multiple Space Manipulators
Yale, G.; Agrawal, B.N. (1994);This paper concerns the cooperative control of multiple manipulators attached to the same base as they reposition a common payload. The theory is easily applied to inertially based problems as well as space based free-floating ... -
