Bayesian Analysis of Contingency Tables [PDF]

open access: yesCommunications in Statistics - Theory and Methods, 2005
The display of the data by means of contingency tables is used in different approaches to statistical inference, for example, to broach the test of homogeneity of independent multinomial distributions. We develop a Bayesian procedure to test simple null hypotheses versus bilateral alternatives in contingency tables.

Contingency and Behavior Analysis [PDF]

open access: yesThe Behavior Analyst, 1995
The concept of contingency is central to theoretical discussions of learned behavior and in the application of learning research to problems of social significance. This paper reviews three aspects of the contingency concept as it has been developed by behavior analysts. The first is the empirical analysis of contingency through experimental studies of

Exploiting Coarse-Grained Parallelism Using Cloud Computing in Massive Power Flow Computation

open access: yesEnergies, 2018
We present a novel architecture of parallel contingency analysis that accelerates massive power flow computation using cloud computing. It leverages cloud computing to investigate huge power systems of various and potential contingencies.

Unique Symbolic Factorization for Fast Contingency Analysis Using Full Newton–Raphson Method

open access: yesEnergies, 2023
Contingency analysis plays an important role in assessing the static security of a network. Its purpose is to check whether a system can operate safely when some elements are out of service.

SAYING AND DOING: A CONTINGENCY‐SPACE ANALYSIS [PDF]

open access: yesJournal of Applied Behavior Analysis, 1987
Correspondences between verbal responding (saying) and nonverbal responding (doing) may be organized in terms of the classes of verbal/nonverbal relations into which particular instances of verbal/nonverbal response sequences can enter. Contingency spaces, which display relations among events in terms of the probability of one event given or not given ...

Theoretical framework about optimal model of operation after intentional attacks considering transmission system switching

open access: yesIteckne, 2021
This research focuses on optimal post-intentional attack operation considering switching transmission systems. The applicable models for this process focus on the application of bi-level optimization methods that are capable of analyzing two possible ...

High-performance computing for static security assessment of large power systems

open access: yesConnection Science, 2023
Contingency analysis (CA) is one of the essential tools for the optimal design and security assessment of a reliable power system. However, its computational requirements rise with the growth of distributed generations in the interconnected power system.

Resilience Maximization in Electrical Power Systems through Switching of Power Transmission Lines

open access: yesEnergies, 2022
This research aims to maximize the resilience of an electrical power system after an N−1 contingency, and this objective is achieved by switching the transmission lines connection using a heuristic that integrates optimal dc power flows (DCOPF), optimal ...
