Novel fuzzy-based optimization approaches for the prediction of ultimate axial load of circular concrete-filled steel tubes

2021

An accurate estimation of the axial compression capacity of the concrete-filled steel tubular (CFST) column is crucial for ensuring the safety of structures containing them and preventing related failures. In this article, two novel hybrid fuzzy systems (FS) were used to create a new framework for estimating the axial compression capacity of circular CCFST columns. In the hybrid models, differential evolution (DE) and firefly algorithm (FFA) techniques are employed in order to obtain the optimal membership functions of the base FS model. To train the models with the new hybrid techniques, i.e., FS-DE and FS-FFA, a substantial library of 410 experimental tests was compiled from openly availa…

Simplified technique for constitutive analysis of SFRC

2014

Steel fibre reinforced concrete (SFRC) has become widespread material in areas such as underground shotcrete structures and industrial floors. However, due to the absence of material models of SFRC reliable for numerical analysis, application fields of this material are still limited. Due to interaction of concrete with fibres, a cracked section is able to carry a significant portion of tensile stresses, called the residual stresses. In present practices, residual stresses used for strength, deflection and crack width analysis are quantified by means of standard tests. However, interpretation of these test results is based on approximation using empirically deduced relationships, adequacy o…

A numerical solution that determines the temperature field inside phase change materials: application in buildings

2013

The use of novel building materials that contain active thermal components would be a major advancement in achieving significant heating and cooling energy savings. In the last 40 years, Phase Change Materials or PCMs have been tested as thermal mass components in buildings, and most studies have found that PCMs enhance the building energy performance. The use of PCMs as an energy storage device is due to their relatively high fusion latent heat; during the melting and/or solidification phase, a PCM is capable of storing or releasing a large amount of energy. PCMs in a wall layer store solar energy during the warmer hours of the day and release it during the night, thereby decreasing and sh…

La reconstrucción de la iglesia de san Juan de Elche y otras empresas neobizantinas de Serrano Peral

2016

Se lleva a cabo el estudio de la reconstrucción de la iglesia San Juan Bautista de Elche por Serrano Peral, a partir del análisis de los documentos custodiados en el Archivo General de la Administración del Estado correspondientes a la Junta Nacional de Reconstrucción de Templos Parroquiales, en los que se ponen de manifiesto dos modos de entender la arquitectura por parte de un mismo autor: un primer proyecto, dentro de las características acciones reconstructivas de la posguerra, y un segundo, enmarcado en los cambios experimentados por la arquitectura española a partir de los años 50, ejemplificadores del quehacer polifacético del arquitecto ilicitano y en el que se destaca su peculiar e…

Relationship between score and coaches’ verbal behavior

2013

Calpe V, Guzman J, Grijalbo C. Relationship between score and coaches’ verbal behaviour. J. Hum. Sport Exerc. Vol. 8, No. Proc3, pp. S728-S737, 2013. The way the coach act the most during the development of the game is meanwhile verbal behaviour directed to their players (Moreno et al., 2000), being it influenced by his own cognitions, motivations, and emotions, together with players behaviours and playing situation (Borrie, 1996; Smoll & Smith, 1989). The aim of this study was to analyse the relationship between a situational variable, the score during the game, and verbal behaviour of handball coaches in competitive situation. To do this, five coaches were analysed in five games. Two vari…

Human Haemato-Endothelial Precursors: Cord Blood CD34+ Cells Produce Haemogenic Endothelium

2012

Embryologic and genetic evidence suggest a common origin of haematopoietic and endothelial lineages. In the murine embryo, recent studies indicate the presence of haemogenic endothelium and of a common haemato-endothelial precursor, the haemangioblast. Conversely, so far, little evidence supports the presence of haemogenic endothelium and haemangioblasts in later stages of development. Our studies indicate that human cord blood haematopoietic progenitors (CD34+45+144-), triggered by murine hepatocyte conditioned medium, differentiate into adherent proliferating endothelial precursors (CD144+CD105+CD146+CD31+CD45-) capable of functioning as haemogenic endothelium. These cells, proven to give…

Role of genetic factors on the effect of additional loading doses and two maintenance doses used to overcome clopidogrel hyporesponsiveness.

2014

Background and objective: Additional loading doses and higher maintenance doses (MDs) have been used to overcome hyporesponsiveness of clopidogrel. We aimed to investigate whether genetic polymorphisms of two cytochromes (CYP2C19 and CYP2C9) and ABCB1 modify effect of such dose-adjustment strategy.Materials and methods: We enrolled 118 patients undergoing elective or acute percutaneous coronary intervention (PCI) with drug eluting stent (DES). Platelet reactivity index (PRI) was measured using the vasodilator-stimulated phosphoprotein (VASP) index and a cut-off value of ≥60% was defined as hyporesponsiveness. Polymorphism of two cytochromes (CYP2C19, CYP2C9) and gene ABCB1 were determined. …
