TL;DR: In this paper, the problem of determining the optimal reactor type as dictated by reaction kinetics is considered, and the problem is formulated such that the axial dispersion coefficient is chosen as a function of reactor residence time to optimize reactor performance.

TL;DR: In this article, a set of differential equations describing the dynamics of the transmission system and connected machines, including the voltage regulators and governors, is formed and the terms of these equations are divided into two groups, the linear terms and the nonlinear terms.
Abstract: A set of differential equations describing the dynamics of the transmission system and connected machines, including the voltage regulators and governors, is formed. The terms of these equations are divided into two groups, the linear terms and the nonlinear terms. The solution of the set of equations as a function of time can then be expressed as a function of the exponential of the matrix formed by the linear terms and an integral. The advantages and disadvantages of this method of approach for solving the transient stability problem on a digital computer are discussed.

TL;DR: Paleocurrent data have been obtained from crossbeds and ripple marks found in the Lower Cambrian Chilhowee Group of eastern Tennessee as mentioned in this paper, which indicate that the major direction of clastic transport during Chilwayee time was toward the southeast.
Abstract: Paleocurrent data have been obtained from cross-beds and ripple marks found in the Lower Cambrian Chilhowee Group of eastern Tennessee. These indicate that the major direction of clastic transport during Chilhowee time was toward the southeast. In addition, the ripple-mark data suggest a shoreline oriented northeast-southwest. Evidently the Chilhowee currents moved primarily down the regional paleoslope to the southeast, perpendicular to the shoreline. Such a transport direction is in opposition to the prevailing current motion (predominantly east to west) inferred from Precambrian sediments below the Chilhowee and from most of the Paleozoic strata above. The reversals in Late Precambrian and Paleozoic current directions reflect changing source areas during the evolution of the southern Appalachian geosyncline.
