Statistical studies on Palynology contents of Late Cretaceous to Paleocene age Gurpi Formation in a surface section in Zagros Basin,SW Iran indicate changes in abundance, species diversity, ratio of Spiniferites to Cyclonephelium (S/C), palynological marine index(PMI) values and organic facies. These palynological variations clearly reflect fluctuations in relative sea-level and depositionalenv...

This paper presents the analytical solution of groundwater response to tidal fluctuation in a coastal multilayer aquifer system consisting of a leaky confined aquifer, a semipermeable layer, and an unconfined aquifer. The semipermeable layer, or the roof of the leaky confined aquifer, extends under the sea. Comparisons are made with solutions derived previously, which considered only a single a...

We have achieved a direct measurement of the thermal fluctuation of a pendulum in an off-resonant and wide frequency region using a laser interferometric gravitational-wave detector. These measurements have been well identified for over one decade by an agreement with a theoretical prediction, which is derived by a fluctuation-dissipation theorem. Thermal fluctuation was dominated by the contri...

In this paper, we investigate the effect of a sharp cash level fluctuation resulting from the inflow and outflow of a large amount of cash and how the cash balance is managed. We describe the cash level evolution as stochastic jump-diffusion process with double exponential distributed jump size, and formulate a cash management model for minimizing the sum of the transaction and holding-penalty ...

Abstract Water-level fluctuation (WLF) is a widespread management action in lakes and reservoirs whose impacts on contaminant fate have seldom been investigated. We used near shore hourly measurements (n = 2122) of turbidity (contaminant proxy) water velocity (sediment resuspension to track high-frequency dynamics during 0.6 m change level observed autumn 2017 large French lake. Simultaneously,...

The flow field and surface adiabatic coolant-film effectiveness (ACE) distribution of a combustor representative effusion cooling array with cylindrical holes has been studied both experimentally numerically. Both studies focus on the influence inflow turbulence, especially high turbulence which is always present in environment but rarely literature. A fluctuating at roughly 20% intensity level...
