Discrete Modeling and Sliding Mode Control of Piezoelectric Actuators
… this research is aimed at developing novel discrete models and discrete SMC (DSMC)-based control schemes for PEAs, along with their experimental validation. The first part of this thesis concerns with the modeling and control of one-degree of freedom (DOF) PEA, which can be treated as a …

Discrete modeling of sculptured surface machining for robust automatic feedrate selection
… software consists of three distinct portions: a discrete mechanistic model, a discrete geometric model, and a CNC machine model. The mechanistic model estimates cutting forces as a function of cut geometry, cutter/stock relative velocity, and material constants. The geometric model keeps track of …

Algebraic Methods for Modeling Gene Regulatory Networks
So called discrete models have been successfully used in engineering and computational systems biology. This thesis discusses algebraic methods for modeling and analysis of gene regulatory networks within the discrete modeling context. The first chapter gives a background for discrete models and …

Modeling and measurement of switching converters
The methods of modeling and measurement of switching converters are discussed in this thesis. The average model is very simple but is inaccurate when modulation frequencies approach to one-half of the switching frequency. The discrete model can accurately predict the modulation envelope of the …

Interactive Procedural Design Exploration for Modular Structures
… paper takes inspiration from recent advances in discrete modeling tools. Under the existing frameworks, aggregations can be generated following either stochastic procedures or deterministic procedures. However, using deterministic systems often yields expected results with limited diversity while …

An Algebraic Approach to Reverse Engineering with an Application to Biochemical Networks
… biological networks by accurately monitoring and modeling their responses to certain types of perturbations. The construction of mathematical models based on observation of these responses, referred to as reverse engineering, is an important step in elucidating the structure and dynamics of such …

Developments in the Extended Finite Element Method and Algebraic Multigrid for Solid Mechanics Problems Involving Discontinuities
… some contributions related to computational modeling and solution of solid mechanics problems involving discontinuities are discussed. The main tool employed for discrete modeling of discontinuities is the extended finite element method and the primary solution method discussed is the …

A Microscopic Continuum Model of a Proton Exchange Membrane Fuel Cell Electrode Catalyst Layer
… O₂ species and ion transport while taking a discrete look at the platinum particles within the active layer. The original 2-dimensional axisymmetric Thin Film and Agglomerate Models of Bultel, Ozil, and Durand [8] were initially implemented, validated, and used to generate various results …

Modeling biological systems with Answer Set Programming
… Answer Set Programming (ASP) as a tool for discrete modeling in Systems Biology. ASP is a declarative problem solving paradigm, in which a problem is encoded as a logic program such that its answer sets represent solutions to the problem. ASP has intrinsic features to cope with …

Polynomial Models for Systems Biology: Data Discretization and Term Order Effect on Dynamics
… makes it inevitable to consider mathematical modeling in order to achieve these goals. The enormous accumulation of experimental data representing the activities of the living cell has triggered an increasing interest in the reverse engineering of biological networks from data. In particular, …
