A review of proper modeling techniques
(Affiliation: University of Michigan, Department of Mechanical Engineering, Ann Arbor, MI, United StatesAffiliation: University of Cyprus, Department of Mechanical and Manufacturing Engineering, Nicosia, CyprusAffiliation: Memorial University of Newfoundland, Department of Engineering and Applied Science, St. John's, NL, CanadaCorrespondence Address: Ersal, T.University of Michigan, Department of Mechanical Engineering, Ann Arbor, MI, United Statesemail: tersal@umich.edu, 2008)
A dynamic system model is proper for a particular application if it achieves the accuracy required by the application with minimal complexity. Because model complexity often - but not always - correlates inversely with ...
Identification of hysteretic systems using the differential evolution algorithm
(Affiliation: Dept. of Mechanichal Engineering, University of Sheffield, Mappin Street, Sheffield S1 3JD, United KingdomCorrespondence Address: Kyprianou, A.Dept. of Mechanichal Engineering, University of Sheffield, Mappin Street, Sheffield S1 3JD, United Kingdomemail: Mep96Gak@sheffield.ac.uk, 1998)
In system identification, it is well-known that any non-linear in the parameters system, possesses a complicated error surface with many local minima. In this case the conventional algorithms, such as those based on least ...
Vortex shedding lock-on in a periodic freestream flow past a circular cylinder
(Publ by ASME, 1993)
Vortex lock-on phenomena in flow past a circular cylinder with a periodic component superimposed on the mean free stream flow is investigated using concepts from dynamical systems (chaos) theory. Numerical results show ...
Compression molding of semi-concentrated fiber suspensions: Flow and fiber orientation
(Publ by ASME, 1993)
The focus of this paper is compression molding of semi-concentrated 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 ...
Three dimensional flow of thixotropic materials in a channel with a sudden expansion using a phenomenological constitutive relation
(Affiliation: WPI, Worcester, United StatesCorrespondence Address: Alexandrou, Andreas N.WPI, Worcester, United States, 1996)
A constitutive relation is proposed that is capable of predicting a wide range of experimental rheological behavior depending on the proper choice of the parameters. The model represents the otherwise discontinuous Bingham ...
Filtering for linear systems driven by fractional Brownian motion
(2000)
In this paper we study continuous time filtering for linear systems driven by fractional Brownian motion processes. We present the derivation of the optimum linear filter equations which involve a pair of functional-differential ...
A novel 3-d model for node and system trust
(2011)
Nowadays, there is an increasing demand for wireless and mobile networks that guarantee secure and reliable data communication among users. To enable data exchanges, authentication mechanisms need to be in place to dynamically ...
The Science in Human Intuition: Optimum Bid Markup Calculations in Competitive Bidding Environments Using Probabilistic Neural Networks
(2000)
The study presented in this paper seeks the development of a model to be used by the construction industry for optimum bid markup calculations in static and non-static competitive bidding environments. The framework presented ...
Data broadcasting in ad-hoc networks of pervasive devices: Modeling and simulations
(2003)
With the rapid growth of wireless networks and demand for services, wireless data broadcast has become a fundamental communication mechanism to enhance the services in ad hoc network of pervasive devices. This work focuses ...
Non-concurrent fault identification in discrete event systems using encoded Petri net states
(2002)
In this paper we extend a previously developed coding-based methodology for monitoring faults in discrete event systems that are described by Petri nets. We present a systematic design that enables us to non-concurrently ...
