Advances in Meteorology, 2016 We compared the spatiotemporal variability of temperatures and precipitation with that of the magnitude and timing of maximum daily spring flows in the geographically adjacent L’Assomption River (agricultural) and Matawin River (forested) watersheds ...

Minimum parametric flow over time
CoRR, 2015 The paper presents a dynamic solution method for dynamic minimum parametric networks flow. The solution method solves the problem for a special parametric dynamic network with linear lower bound functions of a single parameter. Instead directly work on the original network, the method implements a labelling algorithm in the parametric dynamic residual ...

The maximum flow in dynamic networks [PDF]
Computer Science Journal of Moldova, 2005 The dynamic maximum flow problem that generalizes the static maximum flow problem is formulated and studied. We consider the problem on a network with capacities depending on time, fixed transit times on the arcs, and a given time horizon.

Arab Journal of Basic and Applied Sciences, 2018 A two dimensional natural convective flow of nanofluid over a vertical plate in the presence of time-exponential temperature has been studied analytically. We have incorporated the effects of thermophoresis and Brownian motion in the considered nanofluid

The Predictive Power of Future Cash Flow by Earning and Cash Flow [PDF]
Journal of Asset Management and Financing, 2021 The purpose of this study is to investigate the ability of past earnings, compared to past cash flows, to predict future cash flows. A sample of 69 companies was selected, during the years 2004 to 2017, and regression models were applied to analyze the ...

The Impact of Spillback on the Price of Anarchy for Flows over Time [PDF]
, 2020 Flows over time enable a mathematical modeling of traffic that changes as time progresses. In order to evaluate these dynamic flows from a game theoretical perspective we consider the price of anarchy (PoA). In this paper we study the impact of spillback effects on the PoA, which turn out to be substantial.

Atomic Splittable Flow Over Time Games
CoRR, 2020 In an atomic splittable flow over time game, finitely many players route flow dynamically through a network, in which edges are equipped with transit times, specifying the traversing time, and with capacities, restricting flow rates. Infinitesimally small flow particles controlled by the same player arrive at a constant rate at the player's origin and ...

Robust flows over time: models and complexity results [PDF]
Mathematical Programming, 2017 We study dynamic network flows with uncertain input data under a robust optimization perspective. In the dynamic maximum flow problem, the goal is to maximize the flow reaching the sink within a given time horizon $T$, while flow requires a certain travel time to traverse an edge. In our setting, we account for uncertain travel times of flow.

Time-Dependent Dynamical Systems and Geophysical Flows [PDF]
, 2003 This thesis presents a dynamical systems approach to transport and mixing in geophysical flows. First, new algorithms are developed that allow one to study a dynamical system that is described in a variety of ways such as by means of observational data ...
