Non-linear optimized cash flow model
… of a lump-sum project, progress payments (cash inflow) are paid periodically to contractors for project performance. Contractors are required to pay the direct costs (cash outflow) during construction. The net difference between the cash inflow and outflow are the required overdraft, which the …

Improving groundwater flow model parametrization techniques
Numerical modeling of groundwater flow is a powerful tool that can assist in hydrogeological analysis and understanding of groundwater system behavior. However, its results are highly dependent on the proper model parameterization (often, at least partially achieved through calibration). The …

METHODS COMPARISON ON FLOW MODEL CONSTRUCTION AND PARAMETER ESTIMATION
Knowing the equation of an unknown dynamical system is essential when trying to apply optimal control. Sometimes researchers do not have a comprehensive knowledge to a nonlinear system. The unknown part might be the function representing the relation between states (e.g. transfer function), or key …

A potential flow model for separated flow around airfoils
… some new work has been done on the wake source model, a potential flow model for steady separated flow. This work includes some modifications to the model and applications to new geometries. In the wake source model, the body of interest is conformally mapped to a circle. In the transform plane, …

A Potential Flow Model of a Fire Sprinkler Head
… sprinkler sprays fills a critical gap in the modeling of fire suppression systems. Previous research has shown that a modeling framework consisting of an instability model coupled with a stochastic transport model can paint most of the sprinkler spray picture, but requires input in the form of …

A granular flow model of an annular shear cell
… that allow minerals to be extracted are best modelled using granular flows. A single rheological description that captures all the features of granular flows has not yet been realised, although considerable progress towards a complete theory has been made. Existing models of such horizontally …

Plant leaf motion estimation using A 5D affine optical flow model
… plant leaf motion estimation is presented. The model is based on 5D affine optical flow, which allows simultaneous estimation of 3D structure, normals and 3D motion of objects using multi camera data. The method consists of several consecutive estimation procedures. In a first step the affine …

Building a Better Pedestrian Flow Model for the Indianapolis Motor Speedway
… was to study the phenomenon of pedestrian flow as it related to entry gate procedures and resulting impacts. This data was then used to compile modeling scenarios employing AnyLogic computer software that allowed for free-agent, variable play to replicate the conditions of the security …

A Cox proportional hazards-cash flow model for bank failure prediction
This research uses the Cox proportional hazard model and bank cash flow information to determine whether adding cash flow information will improve current bank failure prediction methods. In two published papers it has been shown that the Cox model performs as well as other models with respect to …

A GPU-Enabled Building Block Flow Model for Computational Fluid Dynamics
… with the GPU architecture. This has allowed wall-modeled large eddy simulation (WMLES), a higher fidelity simulation technique, to become practical for industry use. WMLES requires the use of both a sub-grid scale (SGS) model and a wall model in order to close the system of equations for …

An order flow model and a liquidity measure of financial markets
… measure of market liquidity. Various statistical modeling techniques are introduced to model order flow generation, which is a liquidity generation process of the market. The order flow model successively replicates various statistical properties of price returns including fat-tailed distribution …

A synthetic hydrologic flow model for the upper James River Basin
… is the synthetic generation of possible future flows in the James River at Buchanan, Virginia, through the utilization of existing records of monthly precipitation and runoff. Twelve separate monthly regression models were chosen on the basis of the degree of correlation as indicated by the …

A Methodology for Determining the Appropriate Level of Power Flow Model Detail
… operation and management. Improvement of power flow analysis is necessary since it can provide planners and operators with a full understanding of the current and future electric grid. Two main transitions are needed to be considered for better power flow analysis. The first one is increasing …

DEVELOPING A COUPLED MICROSTRUCTURE FLUID FLOW MODEL FOR SOLIDIFICATION IN ADDITIVE MANUFACTURING
… or partially integrated aspect of fluid flow within the melt pool. This fluid flow is crucial as it influences concentration and temperature distribution, impacting microstructure development and therefore material behaviour. To bridge this gap, our project is developing a phase-field …

Development of a Groundwater Flow Model for Hungry Valley, Washoe County, Nevada
… 4, 5, 7 and 8. The objective of this groundwater flow model is to develop optimization strategies to maintain the static water levels as high as possible, minimize the cost of groundwater pumping, and keep arsenic levels below drinking water standards (through blending of pumped groundwater), …

A nonlocal dense granular flow model implemented in the material point method
A nonlocal model for dense granular flow is implemented in the material point method (MPM), an extension of the finite element method (FEM) for solid mechanics. The nonlocal model used has shown great predictive capability for dense flows when implemented in the finite element framework, but …
