3D flow of HerschelBulkley fluids
(ASME, 1998)The flow of HerschelBulkley fluids through a sudden 3D square with expansion height ratio of 2:1 is studied numerically by solving the mass and momentum conservation equations along with a continuous constitutive relation. ...

Algebraic approaches for fault identification in discreteevent systems
(2005)In this note, we develop algebraic approaches for fault identification in discreteevent systems that are described by Petri nets. We consider faults in both Petri net transitions and places, and assume that system events ...

An Algorithm for the Selection of Physical System Model Order Based on Desired State Accuracy and Computational Efficiency
(American Society of Mechanical Engineers (ASME), 2003)In recent years, algorithms have been developed to help automate the production of dynamic system models, The focus of this development has been to create procedures and algorithms that use modeling metrics for generating ...

Application of artificial neural networks in the prediction of earnings
(IEEE, 1994)The feasibility of using artificial neural networks (ANNs) for predicting future earnings by stock market and capital market investors was evaluated. A multilayer perceptron feedforward neural network architecture with an ...

Article
Assignment of natural frequencies by an added mass and one or more springs
(2004)The problem of assigning natural frequencies to a multidegreeoffreedom undamped system by an added mass connected by one or more springs is addressed. The added mass and stiffnesses are determined using receptances from ...

Article
Bid markup selection using artificial neural networks and an entropy metric
(2010)The purpose of the paper is to perform bid markup optimisation through the use of artificial neural networks (ANN) and a metric of the selected bid markup's derived entropy. The scope is to provide an alternative, ...

Article
Biphasic modeling of brain tumor biomechanics and response to radiation treatment
(2016)Biomechanical forces are central in tumor progression and response to treatment. This becomes more important in brain cancers where tumors are surrounded by tissues with different mechanical properties. Existing mathematical ...

Article
Cationic nanoparticles have superior transvascular flux into solid tumors: Insights from a mathematical model
(2013)Despite their great promise, only a few nanoparticle formulations have been approved for clinical use in oncology. The failure of nanoscale drugs to enhance cancer therapy is in large part due to inefficient delivery. To ...

Article
Certain nonlinear partially observable stochastic optimal control problems with explicit control laws equivalent to LEQG/LQG problems
(1997)This paper is concerned with partially observed stochastic optimal control problems when nonlinearities enter the dynamics of the unobservable state and the observations as gradients of potential functions. Explicit ...

Certain results concerning filtering and control of diffusions in small white noise
(IEEE, 1997)The purpose of this talk is twofold. First, we examine in detail the binary hypothesis decision and/or estimation problem using a risksensitive cost criterion, when the state and observation processes are diffusion signals. ...

Compression molding of semiconcentrated fiber suspensions: Flow and fiber orientation
(Publ by ASME, 1993)The focus of this paper is compression molding of semiconcentrated fiber suspensions. During compression molding a premeasured amount of raw material (charge) is placed between two halves of a die. The die is then closed ...

Article
Compression molding using a generalized eulerian–lagrangian formulation with automatic remeshing
(1992)A generalized Eulerian‐Lagrangian approach is used to study the compression molding of viscoelastic polymers. The complete, unsteady, two‐dimensional equations of motion are used in the analysis. The White–Metzner model ...

Article
Computational assessment of distributed decomposition methods for stochastic linear programs
(1998)Incorporating uncertainty in optimization models gives rise to large, structured mathematical programs. Decomposition procedures are wellsuited for parallelization, thus providing a promising venue for solving large ...

Article
Conditional densities for continuoustime nonlinear hybrid systems with applications to fault detection
(1998)Continuoustime nonlinear stochastic differential state and measurement equations, all of which have coefficients capable of abrupt changes at a random time, are considered; finitestate jump Markov chains are used to model ...

Article
Conditional moment generating functions for integrals and stochastic integrals
(2003)In this paper we present two methods for computing filtered estimates for moments of integrals and stochastic integrals of continuoustime nonlinear systems. The first method utilizes recursive stochastic partial differential ...
