The Nymphaeum of the Tritons at Hierapolis of Phrygia (Turkey) from excavations to 3D-virtual reconstruction: an example of integrated methods in the…
2011
The Nymphaeum of the Tritons at Hierapolis of Phrygia is a monumental fountain of the Roman period with an imposing marble façade. Within the activities of the Italian Archaeological Mission the Nymphaeum is currently being studied by a team from the University of Messina with the goal of understanding its original layout and its history. The starting point of the study is the wealth of data provided by stratigraphic excavation of the building, particularly by the extensive archaeological deposits formed by the blocks of the façade collapsed into the pool of the fountain following an earthquake in the 7th century AD. The need to process a large amount of data required the creation of a comp…
Rilievo e ricostruzione virtuale del Ponte Sud di Hierapolis di Frigia (Turchia)
2015
[ES] El artículo se refiere al levantamiento topográfico y la reconstrucción en 3D de un puente-acueducto romano situado inmediatamente al sur de Hierápolis, en Frigia (suroeste de Turquía), a lo largo del antiguo camino dirigido a Colosas, en el interior de Anatolia. Actualmente sólo se conservan su pilar sur y escasos restos del pilar norte. Se encuentra en una situación muy difícil, en el interior de un valle estrecho y profundo, y nunca se ha estudiado antes. Durante la campaña de trabajo de campo de 2011 de la Misión Arqueológica Italiana, fue examinado con un diferencial de alta precisión del sistema GPS (para la documentación del plan y su posicionamiento en el mapa digital arqueológ…
Validation of high voltage power supplies for the 1-inch photomultipliers of AugerPrime, the Pierre Auger Observatory upgrade
2022
In the framework of the upgrade of the Pierre Auger Observatory, a new high voltage module is being employed for the power supply of the 1-inch photomultiplier added to each water-Cherenkov detector of the surface array with the aim of increasing the dynamic range of the measurements. This module is located in a dedicated box near the electronics and comprises a low consumption DC-DC converter hosted inside an aluminum box. All the modules have undergone specific tests to verify their reliability in the extreme environmental conditions of the Argentinian pampa. In this paper, we describe the validation procedure and the facility developed to this aim. The successful results of the tests on …
Brane-world and loop cosmology from a gravity–matter coupling perspective
2015
We show that the effective brane-world and the loop quantum cosmology background expansion histories can be reproduced from a modified gravity perspective in terms of an $f(R)$ gravity action plus a $g(R)$ term non-minimally coupled with the matter Lagrangian. The reconstruction algorithm that we provide depends on a free function of the matter density that must be specified in each case and allows to obtain analytical solutions always. In the simplest cases, the function $f(R)$ is quadratic in the Ricci scalar, $R$, whereas $g(R)$ is linear. Our approach is compared with recent results in the literature. We show that working in the Palatini formalism there is no need to impose any constrai…

Shear design of high strength concrete beams in MRFs
2019
This paper presents the criteria for the shear design of high strength concrete (HSC) beams in moment resisting frames (MRFs). The formulation of an analytical model is provided for the case of beams with longitudinal reinforcement in the presence of transverse stirrups. The model is of additive type, in the meaning that the shear resistance of the beam is evaluated as the sum of several contributions. In particular, the contribution of concrete, longitudinal rebars, and transversal reinforcement are taken into account. Furthermore, for assessing the concrete contribution, a classical approach is followed, according to which two effects arise in the shear mechanism: the arc and the beam eff…
MINE - Mobile Learning in Higher Education
2018
Mobile technologies are an important part of our daily life and we carry them with us all the time. Mobile learning is already used a lot in informal and non-formal learning, but in the context of formal learning it is not much used, yet. In the area of formal learning at universities, there is a great need for pedagogic scenarios to encourage educatorsto use these new technologies. It is suggested that educators will need to move beyond the didactic approaches still frequently found in higher education. Social constructivist approaches have been advocated, along with the development of communities of practice to support educators. In addition, more emphasis on learners is required, to unde…
Towards expert knowledge? A comparison between a constructivist and a traditional learning environment in the university
1999
Abstract This research monograph examines the potential of constructivist learning environments for developing prerequisites of expert knowledge during university studies. Drawing on recent theories of the development of expert knowledge and on the constructivist view of learning, an experiment was conducted in an educational psychology course. The primary purpose of the study was to compare the learning outcomes of students who studied the course material in a constructivist learning environment with those of students who learned it under traditional teaching and studying conditions. Students in the constructivist learning environment acquired more diversified knowledge. In addition, a the…
Gender Effects in Assessment of Economic Knowledge and Understanding: Differences Among Undergraduate Business and Economics Students in Germany, Jap…
2015
Gender effects in large-scale assessments have become an increasingly important research area within and across countries. Yet few studies have linked differences in assessment results of male and female students in higher education to construct-relevant features of the target construct. This paper examines gender effects on students’ economic content knowledge with a focus on construct-relevant explanations. Moreover, we compare gender effects cross-nationally between Germany, Japan, and the United States. To assess economic content knowledge of higher education students, we used translated, adapted, and validated versions of the Test of Understanding in College Economics (TUCE, 4th ed.), …
La porte Saint-André à Autun.
2013
National audience; Sous le règne d’Auguste, aux alentours du changement d’ère, quatre portes urbaines furent construites à Augustodunum : l’entrée tournée vers le nord-est a reçu son nom actuel lorsqu’on installa au Moyen Âge une église dédiée à saint André dans l’une des tours de flanquement de l’ancienne porte de ville. Cette réutilisation partielle de l’édifice antique, à une époque où l’enceinte romaine avait cessé d’être fonctionnelle, contribue à expliquer pourquoi cette porte monumentale est parvenue jusqu’à nous dans un état de conservation aussi exceptionnel.
