Preserving Functional Dependencies

SIAM Journal on Computing, 1981
We show that functional dependency preservation can be tested in polynomial time. We show further that while finding a cover for all embedded dependencies is NP-complete, such a cover can be found in polynomial time if dependencies are preserved.

Rationally Functional Dependence

Journal of Philosophical Logic, 2013
The authors discuss functional dependencies, and compare ontological and rational dependencies. What I call ontological dependencies are the dependencies that are based on the state of nature. Rational dependencies, on the other hand, are game theoretical, and require a free will and a strategy-based approach.

Functional equations involving Sibuya’s dependence function

Aequationes mathematicae, 2018
The authors consider the problem of solving the functional equation \(D_{\mathbf X}(x_1,x_2)=D_{{\mathbf X}_{(t_1,t_2)}}(x_1,x_2)\) for all \(x_1\), \(x_2\), \(t_1\), \(t_2\geq 0\), where \(D_{\mathbf X}(x_1,x_2)\) is the Sibuya's dependence function and \(\mathbf X\) and \({\mathbf X}_{(t_1,t_2)}\) are random vectors defined as \({\mathbf X}=(X_1,X_2)\

Local XML functional dependencies

Proceedings of the fifth ACM international workshop on Web information and data management - WIDM '03, 2003
Keys and functional dependencies play a fundamental role in relational databases where they are used in integrity enforcement and in database design. Similarly, these constraints will play a fundamental role in XML and recently keys and functional dependencies in XML have been defined.

Error-Robust Functional Dependencies

Fundamenta Informaticae, 2004
A database user may be confronted with a relation that contains errors. These errors may result from transmission through a noisy channel, or they may have been added deliberately in order to hide or spoil information. Error-robust functional dependencies provide dependencies that still hold in the case of errors.

Motor Functioning and Alcohol Dependence

Alcoholism: Clinical and Experimental Research, 2007
Background:  Autopsy and neuroimaging research in stably abstinent alcoholics illuminated structural and functional abnormalities in brain areas that organize and coordinate motor functioning. Researchers that used behavioural tasks to measure motor functioning found that abstinent alcoholics perform worse than healthy controls.
