Open-shop scheduling problems are highly complex (NP-Hard), where solution is represented by a permutation of machines order that each job must follow to be processed, and for each job, it can have a different machines order. The main goal in these problems is to reduce consumption resources, and at same time, improving several performance criteria. In this work we propose a computational strategy...
A new tool for the detection and measurement of tree-ring widths in wood was developed for the R environment. This tool, the measuRing package, integrates measurement of tree-ring widths with powerful statistical analyses within the R environment. The package assists in the identification of ring borders on scanned image sections from dendrochronological samples. It processes the image section and...
Motif recognition is key to identify common sequences and specific elements recognized by different proteins such as Transcription Factors or RNA Binding Proteins. One interesting approach to computationally identify motifs consists on using additional sources of information besides the input sequences to guide the motif search. However, depending on the information and input data size the motif recovery...
The relationship between the concentration of silane, the degree of surface coverage and the functionalization of multiwall carbon nanotubes (MWCNTs) upon silanization is experimentally investigated. MWCNT silanization is conducted using a γ-methacryloxypropyltrimethoxy silane varying its concentration with respect to the weight of the MWCNTs from 3.5% to 1000% (10×). Physicochemical characterization...
Styrene-b-ethylene-co-butylene-b-styrene triblock copolymers with variable styrene and ethyl branch contents have been prepared by hydrogenation of the butadiene block in the precursor poly(styrene-b- butadiene-b-styrene)s. Their thermal and mechanical properties and their viscoelastic behaviour have been determined in order to establish the influence of the structure. parameters. Thermal transitions...
