Abstract Interpretation for Probabilistic Termination of Biological Systems

open access: yes, 2009
In a previous paper the authors applied the Abstract Interpretation approach for approximating the probabilistic semantics of biological systems, modeled specifically using the Chemical Ground Form calculus.

Probabilistic dialogue modelling [PDF]

open access: yesProceedings of the 3rd SIGdial workshop on Discourse and dialogue -, 2002
We show how Bayesian networks and related probabilistic methods provide an efficient way of capturing the complex balancing of different factors that determine interpretation and generation in dialogue. As a case study, we show how a probabilistic approach can be used to model anaphora resolution in dialogue.

MeGARA: Menu-based Game Abstraction and Abstraction Refinement of Markov Automata

open access: yes, 2014
Markov automata combine continuous time, probabilistic transitions, and nondeterminism in a single model. They represent an important and powerful way to model a wide range of complex real-life systems. However, such models tend to be large and difficult

Recent methodologies for reliability-based design optimization [PDF]

open access: yesInternational Journal for Simulation and Multidisciplinary Design Optimization, 2008
In the field of Deterministic Design Optimization (DDO), the designer reduces the structural cost without taking into account uncertainties concerning materials, geometry and loading.

An analysis on statistical fatigue property of bearing steel in very high cycle regime under rotating bending

open access: yesNihon Kikai Gakkai ronbunshu, 2018
In S-N diagrams for high strength steels, the duplex S-N curves for surface-initiated fracture and interior inclusion-initiated fracture were usually confirmed in the very high cycle regime.

Model-checking branching-time properties of probabilistic automata and probabilistic one-counter automata

open access: yes, 2015
This paper studies the problem of model-checking of probabilistic automaton and probabilistic one-counter automata against probabilistic branching-time temporal logics (PCTL and PCTL$^*$). We show that it is undecidable for these problems.

Analysis of Non-Linear Probabilistic Hybrid Systems

open access: yes, 2011
This paper shows how to compute, for probabilistic hybrid systems, the clock approximation and linear phase-portrait approximation that have been proposed for non probabilistic processes by Henzinger et al.

Pollinator Behavior Drives Sexual Specializations in the Hermaphrodite Flowers of a Heterodichogamous Tree

open access: yesFrontiers in Plant Science, 2019
Dioecy, the specialization of individuals into either male-only or female-only sexual function, has multiple evolutionary origins in plants. One proposed ancestral mating system is heterodichogamy, two morphs of cross-fertilizing hermaphrodite flowers ...
