In this paper we study a combinatorial optimization problem issued from on-board networks in satellites. In this kind of networks the entering signals (inputs) should be routed to amplifiers (outputs). The connections are made via expensive switches with four links available. The paths connecting inputs to outputs should be link-disjoint. More formally, we call (p, λ, k)−network an undirected g...

The new AASHTO Mechanistic-Empirical Pavement Design Guide (MEPDG) provides pavement analysis and performance predictions for various what-if scenarios. MEPDG performance predictions for anticipated climatic and traffic conditions will depend on the values of the input parameters that characterize pavement materials, layers, design features, and condition. A comprehensive global sensitivity ana...

<span lang="EN-US">One of the key variables to determine level cardiovascular risk is heart rate variability, which associates different metrics such as average RR intervals (average RR), standard deviation (SDRR) and percentage differences greater than 50 ms in (pRR50). Given that these make use measurement units, scales, ranges, it necessary an output intelligible terms, taking input va...
