Thermally-responsive biopolyurethanes from a biobased diisocyanate
(Elsevier, 2015-09)
In this work, segmented biopolyurethanes with thermally-activated shape-memory properties were synthesized and characterized. All the employed starting materials were derived from renewable sources. The macrodiol, which ...
Time consistent expected mean-variance in multistage stochastic quadratic optimization: a model and a matheuristic
(Springer, 2019)
In this paper, we present a multistage time consistent Expected Conditional Risk Measure for minimizing a linear combination of the expected mean and the expected variance, so-called Expected Mean-Variance. The model is ...
Overhang constraint for topology optimization of self-supported compliant mechanisms considering additive manufacturing
(Elsevier, 2019-04)
This work presents a computational procedure for direct integration of Topology Optimization and Additive Manufacturing (AM) technologies for compliant mechanisms design. Many topologically optimized geometries present ...
Thin film nanocomposites based on SBM triblock copolymer and silver nanoparticles: morphological and dielectric analysis
(WILEY-VCH, 2017-07-20)
Hybrid organic/inorganic thin film nanocomposites based on poly(styrene)-b-poly(butadiene)-b-poly(methyl methacrylate) (SBM) triblock copolymer and silver nanoparticles (Ag) have been prepared and characterized. In order ...
Threats and Limitations of Terrestrial Broadcast Attacks
(IEEE, 2018-03)
[EN] The DVB standard does not mandate the use of authentication and integrity protection for transport streams. This allows malicious third parties to replace legitimate broadcasts by overpowering terrestrial transmissions. ...
Análisis de los retos de gestión del paisaje del Bien Pirineos-Monte Perdido tras dos décadas inscrito en la Lista del Patrimonio Mundial de UNESCO (1997-2018)
(Universidad de Alicante, 2019-06-17)
Se realiza un análisis sobre los retos de gestión paisajística que presenta actualmente el Bien transfronterizo Pirineos-Monte Perdido, inscrito en la Lista del Patrimonio Mundial de UNESCO desde 1997. Para ello se analizan ...
Solving math and science problems in the real world with a computational mind
(NAER, 2014)
This article presents a new paradigm for the study of Math and
Sciences curriculum during primary and secondary education. A
workshop for Education undergraduates at four different
campuses (n=242) was designed to ...
Palaeoceanographic and palaeoclimatic changes during the last 37,000 years detected in the SE Bay of Biscay based on benthic foraminifera
(Elsevier, 2020-04-28)
Benthic foraminifera assemblages from a sedimentary core (PP10-12; 701 mwd) from the SE Bay of Biscay allow us to trace palaeoceanographic and palaeoclimatic changes occurred in this region during mid MIS 3 (Marine Isotope ...
The use of traditional media for public communication about medicines: a systematic review of characteristics and outcomes
(Routdledge. Taylor & Francis Group, 2019)
A systematic review was conducted to identify, appraise, and synthesize data from original research investigating the use of traditional media for public communication about medicines. Databases were searched for studies ...
Thermoplastic polyurethanes with glycolysate intermediates from polyurethane waste recycling.
(Elsevier, 2017-10)
The polyol is a major component in polyurethane formulations and therefore introducing to the formulation recycled polyol (obtained during decomposition process) allows decreasing the usage of pure petrochemical components. ...
