Transverse vibrations in existing railway bridges under resonant conditions: Single-track versus double-track configurations
In this paper, the dynamic performance of a certain kind of existing bridge under the action of high-speed railway traffic is addressed. Short-to-medium-span simply supported structures are susceptible to experiencing ...
Dynamic performance of existing high-speed railway bridges under resonant conditions retrofitted with fluid viscous dampers
This paper deals with the application of Passive Control techniques to mitigate the excessive vibrations that short simply supported railway bridges may undergo under the circulation of High-Speed trains. A possible solution ...
Space-time dependence dynamics for birth-death point processes
This paper analyses the space-time interdependency of a spatially explicit birth-death process based on the intensity function. Based on intensity functions, these formulations can be, to some extent, analytically solved ...
Enantioselective nickel-catalyzed conjugate addition of dialkylzinc to chalcones using chiral α-amino amides
A series of α-amino amides derived from natural amino acids (alanine, valine, phenylalanine, isoleucine, and phenylglycine) have been synthesized and fully characterized. Their Ni(II) complexes prepared from Ni(acac)<sub>2</sub> ...
Assessing the impact of organizational learning capability on product innovation performance: An empirical test
This paper examines how organizational learning capability affects product innovation performance. We define organizational learning capability through five dimensions or mechanisms: experimentation, risk taking, interaction ...
Moscow spaces and selection theory
A well-known result on Moscow spaces states that every G<sub>δ</sub>-dense subset of a Moscow space X is C-embedded in X. We present here the selection version of this result and also (by means of two different approaches) ...
Real-time anomaly detection from environmental data streams
(Springer International Publishing, 2015)
Modern sensor networks monitor a wide range of phenomena. They are applied in environmental monitoring, health care, optimization of industrial processes, social media, smart city solutions, and many other domains. All in ...
Enhancing Integrated Indoor/Outdoor Mobility in a Smart Campus
(Taylor & Francis, 2015-11)
A Smart City relies on six key factors: Smart Governance, Smart People, Smart Economy, Smart Environment, Smart Living and Smart Mobility. This paper focuses on Smart Mobility by improving one of its key components: ...
The effects of postharvest carbon dioxide and a cold storage treatment on Tuta absoluta mortality and tomato fruit quality
Tuta absoluta is an invasive pest species that affects tomatoes and other solanaceous crops and is found in Europe and other Mediterranean areas. Hitherto, fumigation with methyl bromide is the only measure used to control ...
Simultaneous determination of carrier lifetime and electron density-of-states in P3HT:PCBM organic solar cells under illumination by impedance spectroscopy
We report new insights into recombination kinetics in poly(3-hexylthiophene):methanofullerene (P3HT:PCBM) bulk heterojunction (BHJ) solar cells, based on simultaneous determination of the density of states (DOS), internal ...
