Reducing the risk of collision of vehicles [PDF]
In order to clarify the method of determining the value of the braking distance to determine the maximum deceleration of the vehicle by braking all wheels ATS when using the differential equation of motion of the car was removed dependence, which more ...

Functional Dependencies with null Markers [PDF]
Functional dependencies are an integral part of database design. However, they are only defined when we exclude null markers. Yet we commonly use null markers in practice. To bridge this gap between theory and practice, researchers have proposed definitions of functional dependencies over relations with null markers.

Prevención de caídas en el adulto mayor: revisión de nuevos conceptos basada en la evidencia
Debido al envejecimiento de la población a nivel mundial, que según estimaciones de la OMS para el año 2050 se llegará a los 2000 millones de personas mayores de 60 años, es de vital importancia analizar la atención de este grupo poblacional y prevenir ...

Entropy Inequalities for Lattices
We study entropy inequalities for variables that are related by functional dependencies. Although the powerset on four variables is the smallest Boolean lattice with non-Shannon inequalities, there exist lattices with many more variables where the ...

Dependent Functional Data [PDF]
This paper reviews recent research on dependent functional data. After providing an introduction to functional data analysis, we focus on two types of dependent functional data structures: time series of curves and spatially distributed curves. We review statistical models, inferential methodology, and possible extensions.

In this paper, we propose a failure mechanism cumulative model that considers the loading history of the load sharing effect in a k-out-of-n system. Three types of failure mechanisms are considered, continuous degradation, compound point degradation, and

Bounds for Functions of Dependent Risks [PDF]
For an \(n\)-variate real function \(\psi\) and a random vector \(X:=(X_1,\dots,X_n)\) the problem of finding the best possible lower bound on the distribution function of \(\psi(X)\) is studied when the marginal distributions of the individual risks \(X_i\) are given and the structure of dependence of \(X\) is partially or completely unknown.

Spin-State Dependence of Exchange-Correlation Holes [PDF]
Applications of density functionaltheory (DFT) in computational chemistry rely on an approximate exchange-correlation (xc) functional. However, existing approximations can fail dramatically for open-shell molecules, in particular for transition-metal ...

Discovering Graph Functional Dependencies [PDF]
This article studies discovery of Graph Functional Dependencies (GFDs), a class of functional dependencies defined on graphs. We investigate the fixed-parameter tractability of three fundamental problems related to GFD discovery. We show that the implication and satisfiability problems are fixed-parameter tractable, but the validation problem is co-W[1]
