On the Discovery of Relaxed Functional Dependencies
Proceedings of the 20th International Database Engineering & Applications Symposium on - IDEAS '16, 2016Functional dependencies (fds) express important relationships among data, which can be used for several goals, including schema normalization and data cleansing. However, to solve several issues in emerging application domains, such as the identification of data inconsistencies or patterns of semantically related data, it has been necessary to relax ...

A relaxation function with distribution of relaxation times
Physics Letters A, 1970Abstract A dispersion function based on mixed second order kinetics is interpreted as a linear dispersion system with infinite many relaxators explicitly given.

Approximate Relaxation Function for Concrete
Journal of the Structural Division, 1979Presented is an approximate algebraic formula for calculating the relaxation function for aging concrete. The formula is general; it applies to any form of the creep function. Compared to the previously used effective modulus method, the formula reduces the error from up to 37% to within 2% relative to the exact solution according to the superpositon ...

On compatibility functions in probabilistic relaxation
Photogrammetria, 1985Abstract The first stage in the analysis of remotely sensed data is image segmentation and classification. The early approaches to this problem were based on the Bayesian decision rule for classifying pixels x on individual basis. Recent studies showed that the segmentation performance can be considerably enhanced by incorporating contextual ...

Semicontinuity and relaxation of L ∞-functionals [PDF]
Advances in Calculus of Variations, 2009 Fixed a bounded open set Ω of R , we completely characterize the weak* lower semicontinuity of functionals of the form F (u,A) = ess sup x∈A f(x, u(x), Du(x)) defined for every u ∈ W 1,∞(Ω) and for every open subset A ⊂ Ω. Without a continuity assumption on f(·, u, ξ) we show that the supremal functional F is weakly* lower semicontinuous if and only if

On the behaviour of the spin relaxation function
Il Nuovo Cimento B, 1972The integrodifferential equation governing the time behaviour of the longitudinal spin relaxation function in the high-temperature approximation is studied. The analysis clarifies the consistency of possible approximations to the kernel with the asymptotic behaviour of the solution. It is found that the presence or absence of exchange interaction leads

Relaxation function for the non-Debye relaxation spectra description
Chemical Physics, 2014Abstract This study presents the new relaxation function describing the non-Debye relaxation phenomena. The relaxation function is based on a new theoretical model of the relaxation polarization. The non-Debye relaxation is explained with the model of nonlinear damped oscillator.

Stress relaxation function of glass
Solid State Communications, 1971It has been found by Douglas and others that the stress relaxation function of glass has the form S = S0 exp[ -(t/τ)α]. Simple phenomenological considerations, utilizing the theory of Brownian motion, can explain this law and yield proper values of α and τ.

Relaxation functions in dipolar materials
Journal of Statistical Physics, 1995We compare two simple “cartoons” of relaxation processes in dipolar materials: the “first passage” relaxation function introduced by K. Weron (1991) and the “average” relaxation function expressing the proportion of dipoles which did not change their imposed aligned orientation up to a certain time, the latter providing a description closer to what is ...
