On the Edge-Connectivity of an Uncertain Random Graph

open access: yesIEEE Access, 2020
Connectivity is one of the most important concepts in graph theory. When graph theory is applied to complex systems with indeterminate factors, uncertainty and randomness are two basic types of indeterminacy.

Reliability analysis for the fractional-order circuit system subject to the uncertain random fractional-order model with Caputo type

open access: yesJournal of Advanced Research, 2021
Introduction: According to the competing failure theorem, the fractional-order Resistor Capacitance (RC) circuit system suffers not only from internal degradation but also from external shocks. However, due to the general differences of each failure type

Chance theory: A separation of riskless and risky utility [PDF]

open access: yesJournal of Risk and Uncertainty, 2022
AbstractIn a temporal context, sure outcomes may yield higher utility than risky ones as they are available for the execution of plans before the resolution of uncertainty. By observing a disproportionate preference for certainty, empirical research points to a fundamental difference between riskless and risky utility.

Narrative Complexity and the Case of Pfitz: An Update for the ‘Systems Novel’

open access: yesInterlitteraria, 2021
Recent narrative studies of complexity theory have shown that so-called ‘emergent complexity’ does not accommodate to narrative form. Complexity theory is an interdisciplinary field of study that researches how large-scale phenomena emerge from simple ...

Bacterial evolution and the Bak-Sneppen model [PDF]

open access: yes, 2001
Recently, Lenski et al \cite{Elena,Lenski,Travisano} have carried out several experiments on bacterial evolution. Their findings support the theory of punctuated equilibrium in biological evolution. They have further quantified the relative contributions

Sample- and segment-size specific Model Selection in Mixture Regression Analysis [PDF]

open access: yes, 2006
As mixture regression models increasingly receive attention from both theory and practice, the question of selecting the correct number of segments gains urgency.

A Credibility Theory-Based Robust Optimization Model to Hedge Price Uncertainty of DSO with Multiple Transactions

open access: yesMathematics, 2022
This paper addresses the deregulated electricity market arising in a distribution system with an electricity transaction. Under such an environment, the distribution system operator (DSO) with a distributed generator faces the challenge of electricity ...

Theory of Aces: Fame by Chance or Merit? [PDF]

open access: yesThe Journal of Mathematical Sociology, 2006
We study empirically how fame of WWI fighter-pilot aces, measured in numbers of web pages mentioning them, is related to their achievement or merit, measured in numbers of opponent aircraft destroyed. We find that on the average fame grows exponentially with achievement; to be precise, there is a strong correlation (~0.7) between achievement and the ...
