BRCs (bioretention cells), one of many low-impact development (LID) practices, are increasingly utilized to lessen the amount runoff while simultaneously improving quality. Because goal and LID designs, in general, is mimic or replicate pre-development hydrology, it critical evaluate hydrologic ecologic performances BRC facility from perspective replicating hydrology. The metrics developed this...

In this paper, we systemally study the long time behavior of the curve shortening flow in a closed or non-compact complete locally Riemannian symmetric manifold. Assume that we have a global flow. Then we can exhibit a a limit for the global behavior of the flow. In particular, we show the following results. 1). Let M be a compact locally symmetric space. If the curve shortening flow exists for...

In situ elevated temperature investigations using fly ash based geopolymers filled with alumina aggregate were undertaken. Compressive strength and short term creep tests were carried out to determine the onset temperature of viscous flow. Fire testing using the standard cellulose curve was performed. Applying a load to the specimen as the temperature increased reduced the temperature at which ...

In this paper, we consider a kind of area preserving non-local flow for convex curves in the plane. We show that the flow exists globally, the length of evolving curve is non-increasing, and the curve converges to a circle in C∞ sense as time goes into infinity.

We propose a segmentation method for vector fields that employs geometrical curve attributes to classify the behavior of the integral curves. In particular, we assign to a given spatio-temporal position the attribute value associated with the integral curve initiated at that point. With this attribute information, our segmentation strategy first performs a region classification. Then, connected...

polarization for au/pb(zr ti )o /yba cu o ferroelectric capacitor has been studied and measured by pulse method. a sequence of pulses with amplitudes varying from 0 to 10 volts in 2 volt steps is applied and a conventional polarization curve is obtained by integrating the charge flow from the polarization switching induced by the voltage ramp. a value of 25?c/cm2 is measured for the saturated p...
