Amyloid-like self-assembly of a dodecapeptide sequence from the adenovirus fiber shaft: Perspectives from molecular dynamics simulations
(2011)Peptide and protein self-assembly is related to the fundamental problems of protein folding and misfolding and has potential applications in medicine, materials science and nanotechnology. Sequence repeats from self-assembling ...

Direct observation of excitons in polymer/carbon nanotube composites at room temperature: The influence of nanotube concentration
(2008)In this work, we have employed spectroscopic ellipsometry technique to study the optical properties of polymer/carbon nanotube (CN) composites as a function of nanotube concentration. Using a two-layer structural model ...

Extension and application of an algorithm for systematic identification of weak coupling and partitions in dynamic system models
(2009)This paper reviews and extends a technique to detect weak coupling (one-way coupling or complete decoupling) among elements of a dynamic system model, and to partition and reduce models in which weak coupling is found. The ...

Quality control for structural credit risk models
(2008)Over the last four decades, a large number of structural models have been developed to estimate and price credit risk. The focus of the paper is on a neglected issue pertaining to fundamental shifts in the structural ...

Reachability analysis for a class of petri nets
(2009)In this paper, we study the reachability problem for the class of (strictly) monotone Petri nets that we define based on algebraic conditions. More specifically, given a (strictly) monotone Petri net, an initial marking ...

A review of proper modeling techniques
(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 simulation ...

Sensor selection for structural observability in discrete event systems modeled by petri nets
(2010)This paper studies optimal sensor selection in discrete event systems modeled by partially observed Petri nets. The goal is to place a minimum number of sensors while maintaining structural observability, i.e., the ability ...

Systematic assessment of rigid internal combustion engine dynamic coupling
(2008)Accurate estimation of engine vibrations is essential in the design of new engines, engine mounts, and the vehicle frames to which they are attached. Mount force prediction has traditionally been simplified by assuming ...

Verification of K-step opacity and analysis of its complexity
(2009)In this paper, we analyze the verification of K-step opacity in discrete event systems that are modeled as (possibly non-deterministic) finite automata with partial observation on their transitions. A system is K-step ...
