Galah is an ongoing high-resolution spectroscopic survey with the goal of disentangling the formation history of the Milky Way using the fossil remnants of disrupted star formation sites that are now dispersed around the Galaxy. It is targeting a randomly selected magnitude-limited (V ≤ 14) sample of stars, with the goal of observing one million objects. To date, 300,000 spectra have been obtained. Not all of them are correctly processed by parameter estimation pipelines, and we need to know about them. We present a semi-automated classification scheme that identifies different types of peculiar spectral morphologies in an effort to discover and flag potentially problematic spectra and thus help to preserve the integrity of the survey results. To this end, we employ the recently developed dimensionality reduction technique t-SNE (t-distributed stochastic neighbor embedding), which enables us to represent the complex spectral morphology in a two-dimensional projection map while still preserving the properties of the local neighborhoods of spectra. We find that the majority (178,483) of the 209,533 Galah spectra considered in this study represents normal single stars, whereas 31,050 peculiar and problematic spectra with very diverse spectral features pertaining to 28,579 stars are distributed into 10 classification categories: hot stars, cool metal-poor giants, molecular absorption bands, binary stars, Hα/Hβ emission, Hα/Hβ emission superimposed on absorption, Hα/Hβ P-Cygni, Hα/Hβ inverted P-Cygni, lithium absorption, and problematic. Classified spectra with supplementary information are presented in the catalog, indicating candidates for follow-up observations and population studies of the short-lived phases of stellar evolution.
The Equilibrium Temperature of Planets in Elliptical Orbits
Authors: Méndez Abel , Rivera-Valentín Edgard G.
Published: February 2017

There exists a positive correlation between orbital eccentricity and the average stellar flux that planets receive from their parent star. Often, though, it is assumed that the average equilibrium temperature would correspondingly increase with eccentricity. Here, we test this assumption by calculating and comparing analytic solutions for both the spatial and temporal averages of orbital distance, stellar flux, and equilibrium temperature. Our solutions show that the average equilibrium temperature of a planet, with a constant albedo, slowly decreases with eccentricity until converging to a value 90% that of a circular orbit. This might be the case for many types of planets (e.g., hot Jupiters); however, the actual equilibrium and surface temperature of planets also depend on orbital variations of albedo and greenhouse. Our results also have implications in understanding the climate, habitability, and the occurrence of potential Earth-like planets. For instance, it helps explain why the limits of the habitable zone for planets in highly elliptical orbits are wider than expected from the mean flux approximation, as shown by climate models.
Les dynamiques du champ migratoire colombo-espagnol en temps de crise : ré-émigrations ou migrations de retour ?
Authors: Sierra-Paycha Célio
Published: February 2017

Le système migratoire colombo-espagnol a connu une augmentation exponentielle des départs de la Colombie vers l’Espagne entre 1996 et 2006. Les années 2007 et 2008 correspondent à une période de transition. Tandis que l’Espagne sort de la période la plus prospère de son histoire depuis la fin du franquisme pour entrer dans une phase de récession économique et de crise de l’emploi, la Colombie se remet peu à peu de la crise économique de la fin des années 1990. Cette situation aurait pu laisser penser qu’une inversion des flux migratoires entre la Colombie et l’Espagne allait se produire. L’étude que nous avons menée à partir des microdonnées des variations résidentielles issues des registres de population espagnols permet de confirmer que les flux de départ des Colombiens d’Espagne sont désormais supérieurs aux flux d’immigration colombienne. Elle montre cependant que la tendance actuelle est à une ramification du champ migratoire colombo-espagnol. En effet, de plus en plus de Colombiens ré-émigrent vers un pays tiers (Royaume-Uni, Allemagne, France, États-Unis, Venezuela), au lieu de rentrer chez eux. La diversité des parcours migratoires des Colombiens doit s’analyser au regard des ressources dont disposent les migrants.

Quel pilotage de la performance par les tableaux de bord à l’hôpital public ? À propos d’un cas français
Authors: Dos Santos Catherine , Mousli Morad
Published: February 2017

La recherche s’intéresse à la nécessité et à la façon d’introduire un tableau de bord comme dispositif de pilotage de la performance au sein du contrôle de gestion à l’hôpital public traditionnellement attaché au contrôle budgétaire des résultats. Elle s’appuie sur l’étude de cas longitudinale d’un centre hospitalier universitaire fondée sur une série d’entretiens semi-directifs conduits auprès des différentes parties prenantes du contrôle. Les résultats montrent une prévalence des activités de mesure sur les activités de pilotage en raison, d’une part, de la prégnance des budgets et, d’autre part, d’un tableau de bord peu enclin à favoriser la cohérence de management des performances économiques et médicales par les différents responsables ainsi qu’une bonne coopération interprofessionnelle.
Le collectionneur : un habitus excentrique
Authors: Tacussel Patrick
Published: February 2017

Archéologue des mots et des choses, Balzac est un ethnométhodologue pour qui faire et parler sont des représentations connotatives du monde quotidien ; c’est pour cette raison que le fait social est inséparable de la mise en scène, de l’explicitement symbolique, qu’il est un langage dont les morphèmes et phonèmes composent la grammaire particulière de la vie en société. La comédie est la métaphore des relations sociales en tant que langage, et la métaphore de ce langage comme relation intersubjective.

Are Wearables Good or Bad for Society?
Authors: Hein Daniel W. E. , Jodoin Jennah L. , Rauschnabel Philipp A. , Ivens Björn S.
Published: February 2017

Recent market research forecasts predict that a new form of wearable devices will soon influence the media landscape: Augmented Reality Smart Glasses. While prior research highlights numerous potentials in personal and professional settings of smart glasses, this technology has also triggered several controversies in public discussions, for example, the risk of violating privacy and copyright laws. Yet, little research addresses the questions of whether smart glasses are good or bad for societies, and if yes, why. This study conducts exploratory research to contribute to narrowing this gap. Based on a survey among consumers, the authors identify several societal benefits and risks that determine consumers' evaluation of the anticipated and desired success of smart glasses. These findings lead to numerous important implications for consumers, scholars, managers, and policy makers.

Published: February 2017

With the introduction of Google Cardboard, a combination of mobile devices, Virtual Reality (VR) and making was created. This “marriage” opened a wide range of possible, cheap Virtual Reality applications, which can be created and used by everyone. In this chapter, the potential of combining making, gaming and education is demonstrated by evaluating an implemented math-game prototype in a school by pupils aged 12-13. The aim of the virtual reality game is to solve math exercises with increasing difficulty. The pupils were motivated and excited by immerging into the virtual world of the game to solve exercises and advance in the game. The results of the evaluation were very positive and showed the high motivational potential of combining making and game-based learning and its usage in schools as educational instrument.

ZatLab Gesture Recognition Framework
Authors: Baltazar André
Published: February 2017

The main problem this work addresses is the real-time recognition of gestures, particularly in the complex domain of artistic performance. By recognizing the performer gestures, one is able to map them to diverse controls, from lightning control to the creation of visuals, sound control or even music creation, thus allowing performers real-time manipulation of creative events. The work presented here takes this challenge, using a multidisciplinary approach to the problem, based in some of the known principles of how humans recognize gesture, together with the computer science methods to successfully complete the task. This paper is a consequence of previous publications and presents in detail the Gesture Recognition Module of the ZatLab Framework and results obtained by its Machine Learning (ML) algorithms. One will provide a brief review the previous works done in the area, followed by the description of the framework design and the results of the recognition algorithms.

The project is consubstantiated at an online platform that aims to foster the creation and web hosting of Interactive Cinema in its different variables.
The Use of Mobile Applications in Shopping
Authors: Mäki Marko , Kokko Teemu
Published: February 2017

This exploratory paper focuses on the use of mobile applications in shopping from the customer activation point of view. Empirical survey data was collected from 23 mobile shopping application users, and the major findings indicate that mobile applications present a modern and flexible channel for supporting and intensifying customer participation. However, in order to guarantee a long-term customer relationship, the application must be integrated with the service development and refinement activities of a service company. It is also essential that applications have a high technological quality and create a long-term relationship between the customer and the company based on a cumulative learning process. In addition, the motivation to upload the application is strongly based on the perceived benefits of using the application. Therefore, it seems beneficial to develop mobile applications in conjunction with customers. In all, more research is needed, ideally involving close co-operation between practitioners and academic researchers.

This paper analyzes the odd-even policy in Delhi using tweets posted on Twitter from December 2015 to August 2016. Twitter is a social network where users post their feelings, opinions and sentiments for any event. This paper transforms the unstructured tweets into structured information using open source libraries. Further objective is to build a model using Deep Belief Networks classification (DBN) to classify unseen tweets on the same context. This paper collects tweets on this event under six hashtags. This study explores three freely available resources / Application Programming Interfaces (APIs) for labeling of tweets for academic research. This paper proposes three sentiment prediction models using the sentiment predictions provided by three APIs. DBN classifier is used to build six models. The performances of these six models are evaluated through standard evaluation metrics. The experimental results reveal that the TextBlob API and proposed Preference Model outperformed than the other four sentiment prediction models.
Appraisal Inference from Synthetic Facial Expressions
Authors: Sergi Ilaria , Fiorentini Chiara , Trznadel Stéphanie , Scherer Klaus R.
Published: February 2017

Facial expression research largely relies on forced-choice paradigms that ask observers to choose a label to describe the emotion expressed, assuming a categorical encoding and decoding process. In contrast, appraisal theories of emotion suggest that cognitive appraisal of a situation and the resulting action tendencies determine facial actions in a complex cumulative and sequential process. It is feasible to assume that, in consequence, the expression recognition process is driven by the inference of appraisal configurations that can then be interpreted as discrete emotions. To obtain first evidence with realistic but well-controlled stimuli, theory-guided systematic facial synthesis of action units in avatar faces was used, asking judges to rate 42 combinations of facial actions (action units) on 9 appraisal dimensions. The results support the view that emotion recognition from facial expression is largely mediated by appraisal-action tendency inferences rather than direct categorical judgment. Implications for affective computing are discussed.

Arc Fusion Welding of Mg-Al2Ca-Added Al 5xxx Alloys
Authors: Kang Min Jung , Kim Cheol Hee
Published: February 2017

When casting ECO Al alloys, Mg-Al2Ca is used as a substitute for elemental Mg during the alloying process. Several previous studies have determined the mechanical and metallurgical properties of the ECO Al 5052 alloy. In this study, the weldability of the ECO Al 5052 alloy was determined. Gas metal arc welding was performed, and the resultant mechanical and metallurgical aspects of the welds in ECO Al 5052 alloy and commercial Al 5052 alloy were examined. In comparison to the commercial Al 5052 alloy specimen, the welds produced in the ECO Al 5052 alloy exhibited a very narrow heat-affected zone and were not softened through grain coarsening. Consequently, almost 100% joint efficiencies were observed in ECO Al alloy welds, in comparison to joint efficiencies of only 82% in conventional Al 5052 alloy welds.

Published: February 2017

As part of the Great Lakes International Multidisciplinary Program on Crustal Evolution (GLIMPCE), approximately 1350 km of deep reflection data were recorded along eight lines in Lakes Superior, Michigan and Huron. The survey was designed to resolve the deep
structure of the Midcontinent Rift and the Hemlo and Michipicoten Granite/Greenstone Belts in Lake Superior, the Grenville Front and Huronian continental margin in Lake Huron and the Penokean Orogen and Niagara Fault in Lake Michigan. Data were generated using an approx. 128 litre airgun array,
recorded with a 120 channel streamer, conventionally processed i~ CMP geometry, and migrated. The migrated data presented in this report are plotted at 1:200000. This format allows interested parties to interpret the data independently and to compare directly the results with a wide variety of
seismic reflection data being released by other groups.
Flooding from the July 18-21, 1996 rainstorm in the Saguenay area, Quebec: fluvial geomorphic effects and slope stability along selected major river reaches
Authors: Brooks G R , Lawrence D E , Fung K , Bégin C , Perret D
Published: February 2017

A major storm system stalled over the mouth of the St. Lawrence River from July 18-21, 1996 and dropped record amounts of rain causing widespread flooding in southern Quebec. Flooding was particularly severe along river systems south of the Saguenay-Lac Saint
Jean area, where rainfall in excess of 200 mm fell within a 36 hour period.
The flooding caused severe geomorphic effects along five rivers in the area. These effects varied considerably both between rivers and from reach to reach along the same river. Along the Rivière aux Sables and Chicoutimi Rivière, the flooding caused dramatic, yet localized, lateral bank
erosion and incision adjacent to a number of small dams creating deep channels which carried the post-flood flow around the dams. Elsewhere, negligible to moderate bank erosion and sedimentation occurred along the river banks and floodplains. Major lateral channel erosion and avulsions occurred
along the lower 10 km of Rivière à Mars causing extensive destruction of the floodplain and erosion of terraces along the valley bottom. Negligible to minor geomorphic changes occurred along the lower 17 km of Rivière du Moulin; there being little evidence of the recent flood along
long reaches of the river valley.
The worst flooding in the region occurred along Rivière des Ha!Ha! where the overtopping and erosion of an earthfill dyke caused the drainage of Lac Ha!Ha! reservoir. The geomorphic effects of the flooding varied downstream along the alluvial sections of the river. In general, wide, relatively
gently-sloped reaches of valley bottom experienced considerable accretion of sand and silt (up to several metres) and negligible to minor erosion. Major channel incision and moderate channel widening occurred along confined, relatively steeply-sloped sections of valley. Along similarly sloped, but
much wider reaches of valley, major channel widening with minor to negligible incision occurred, resulting in the reworking of large areas of the floodplain and the erosion of the valleysides.
Associated with the flooding, a number of landslides occurred along the five study rivers. Most failures were shallow and of limited extent, although two retrogressive slides caused damage to infrastructure and buildings. Triggering mechanisms for the landslides included bank erosion, saturation of
the ground from the rainfall, drawdown of reservoirs and recession of flood waves; or a combination of the above. Overall, landsliding along the river banks was a relative minor part of the flood impacts.
The doctrine of providence in the Institutes of Calvin – still relevant?
Authors: Coetzee C.F.C.
Published: February 2017

In the reformed tradition and theology, the doctrine of provi- dence has always been important and relevant, so much so that it forms an integral part of the reformed confessions. At the same time some of the most difficult theological questions are raised regarding this doctrine, questions like the following: Is God in control of everything? What is the relationship between the providence of God and sin, suffering, man’s responsibility, et cetera? In our times the doctrine as such is questioned or even rejected. What makes this topic even more important is the commemoration of the publication of Darwin’s book, “The origin of species”, coupled with the renewed emphasis on Darwinism, evolutionism and atheism.1 From the perspective of the Calvinistic-reformed theology and in the light of the com- memoration of Calvin’s birth 500 years ago, it is important to determine the relevance of Calvin’s thoughts on a number of important issues in the current debate, e.g. the doctrine on God, providence and creation, sin, suffering, et cetera. It is also determined that Calvin’s thoughts are reflected in the reformed confessions, which is still the living faith of reformed churches all over the world.
The influence of John Calvin’s theology on the World Council of Churches
Authors: Van Wyk G.M.J.
Published: February 2017

This article explores the question whether any traces of Calvin’s theological views on church unity can be found in the purpose statements and goals of the World Council of Churches (WCC). Although no direct influence of Calvin’s theology on the work of the WCC can be proved, the structure and content of Calvin’s thought on church unity can be recognised in the statements and work of the WCC. Calvin believed that true church unity is not in the first place a unity of church structures, but one of truth, love, hope and confession. The ecumenical movement is in agreement with Calvin in this regard.  The ecumenical movement and the World Council of Churches are products of modern culture. The ecumenical movement could not have developed in a world that is not tolerant and where the free use of reason is not one of the core values of society. The ecumenical movement is also the natural answer to the problem of religious division that pre-modern Europe left us with. After a brief description of the World Council of Church- es as a modern institution the influence of Calvin’s theology on the theology of the World Council of Churches is explored.
A comparison of two chemistry and aerosol schemes on the regional
scale and resulting impact on radiative properties and warm and
cold aerosol-cloud interactions
Authors: Glassmeier Franziska , Possner Anna , Vogel Bernhard , Vogel Heike , Lohmann Ulrike
Published: February 2017

Abstract. The complexity of the atmospheric aerosol causes large uncertainties in its parameterization in atmospheric models. In a process-based comparison of two aerosol and chemistry schemes within the regional atmospheric modeling framework COSMO-ART, we identify key sensitivities of aerosol parameterizations. We consider the aerosol module MADE in combination with full gas-phase chemistry and the aerosol module M7 in combination with a constant-oxidant-field-based sulfur cycle. For a Saharan dust outbreak reaching Europe, modeled aerosol populations are more sensitive to structural differences between the schemes, in particular the consideration of aqueous-phase sulfate production, the selection of aerosol species and modes and modal composition, than to parametric choices like modal standard deviation and the parameterization of aerosol dynamics. The same observation applies to aerosol optical depth (AOD) and the concentrations of cloud condensation nuclei (CCN). Differences in the concentrations of ice-nucleating particles (INP) are masked by uncertainties between two ice-nucleation parameterizations and their coupling to the aerosol scheme. Differences in cloud droplet and ice crystal number concentrations are buffered by cloud microphysics as we show in a susceptibility analysis.
Combining regional rainfall frequency analysis and rainfall-runoff modelling to derive frequency distributions of peak flows in ungauged basins: a proposal for Sicily region (Italy)
Authors: Bonaccorso Brunella , Brigandì Giuseppina , Aronica Giuseppe Tito
Published: February 2017

Abstract. In the present study an attempt is made to provide a general Monte Carlo approach for deriving flood frequency curves in ungauged basins in Sicily region (Italy). The proposed procedure consists of (i) a regional frequency analysis of extreme rainfall series, combined with Huff curves-based synthetic hyetographs, for design storms and (ii) a rainfall-runoff model, based on the Time-Area technique, to generate synthetic hydrographs. Validation of the procedure is carried out on four gauged river basins in Sicily region (Italy), where synthetic peak flow frequency curves, obtained by simulating 1000 flood events, are compared with observed values. Results of the application reveal that the proposed Monte Carlo approach is suitable to reproduce with reasonable accuracy the hydrologic response of the investigated basins. Given its relative simplicity, the developed procedure can be easily extended to poorly gauged or ungauged basins.
UNDERGROUND SURVEYING: 16TH CENTURY CELLAR VAULTS IN THE GALERÍA
DE CONVALECIENTES, MONASTERY OF SAN LORENZO DEL ESCORIAL
Authors: Chías P. , Abad T. , Echeverría E. , De Miguel M. , Llorente P.
Published: February 2017

Abstract. Underground surveying of cellars, caves, and architectural spaces, is quite different from surveying on the surface. Researchers must deal with various challenges derived of the lack of natural light, low temperature, and humidity, but also with inaccessibility. But the essential problem in underground surveying is that of orientating the underground surveys to the surface surveys. For this purpose our methodology integrates different geomatic techniques, as the use of a scanner laser in order to obtain a 3D model, as well as classic topography, and GPS to locate accurately the control points according to the official reference frame of the Spanish Geodetic Network. The developed methodology is described and applied to the case study of the cellars of the Gallery of Convalescents (Galería de Convalecientes) in the Royal Monastery of San Lorenzo de El Escorial. These cellars compose an outstanding series of interrelated singular complex spaces. Their study is particularly relevant because of the quality of the stonework, the geometry of the vaults and lunettes, and the stereotomy. The fact that these spaces were neither surveyed nor studied before, must be stressed. And our work will bring into light an important part of the 16th century Spanish architectural heritage. Finally, the INSPIRE Directive becomes an opportunity to integrate cultural heritage datasets into an interoperable framework, and to share and diffuse them as geographic information.
SURVEYING THE UNDERWATER ARCAHEOLOGICAL SITE OF CAPE GLAROS AT
PAGASETIKOS GULF
Authors: Diamanti E. , Spondylis E. , Vlachaki F. , Kolyva E.
Published: February 2017

Abstract. The Hellenic Institute of Marine Archaeology (H.I.M.A.)1 has been conducting an underwater archaeological research in the west coast of southern Pagasetikos Gulf, since 2000. Every year the underwater research focuses on specific archaeological targets that have been recovered during previous field campaigns. The current publication elaborates on the comprehensive documentation of the underwater archaeological site at Cape Glaros, during the 2015 field season, under the direction of the archaeologist Elias Spondylis. The 2015 research campaign was conducted within the framework of the ITACA- Innovation Technologies and Applications for Coastal Archaeological sites European Project (FP7/2007-2013, GA No 606805), at two archaeological sites, namely the Cape Glaros and Metohi. It was among the most important challenges of the project to successfully produce the detailed and accurate 3D mapping of the Cape Glaros site that covers an extended area. Four large concentrations of pottery finds and numerous anchors of different typology have been recorded, that can be dated from the late Hellenistic to the Byzantine periods. This challenge was tackled through the simultaneous implementation of three recording methods; photogrammetry, geodesy and conventional architectural mapping. The workflow of the documentation process, including data acquisition, processing and graphic visualization, along with the derived results are presented below. 1The Hellenic Institute of Marine Archaeology (H.I.M.A.) is a private, non-profit organization, founded in 1973, which undertakes maritime archaeological research under the supervision or in collaboration with the Greek Ministry of Culture. It has over 100 members, with diverse academic credentials, all of whom work, mainly, on a voluntary basis. 3D recording of underwater archaeological sites has been applied to numerous projects that have been carried out by the multidisciplinary team of H.I.M.A. in locations of utmost archaeological importance and interest, such as Modi island (Poros) and numerous wreck sites in Pagasetikos and South Euboean (Diamanti, Vlachaki, 2015) Gulfs and others.
INTEGRATED DATA CAPTURING REQUIREMENTS FOR 3D SEMANTIC MODELLING OF CULTURAL HERITAGE: THE INCEPTION PROTOCOL
Authors: Di Giulio R. , Maietti F. , Piaia E. , Medici M. , Ferrari F. , Turillazzi B.
Published: February 2017

Abstract. The generation of high quality 3D models can be still very time-consuming and expensive, and the outcome of digital reconstructions is frequently provided in formats that are not interoperable, and therefore cannot be easily accessed. This challenge is even more crucial for complex architectures and large heritage sites, which involve a large amount of data to be acquired, managed and enriched by metadata. In this framework, the ongoing EU funded project INCEPTION – Inclusive Cultural Heritage in Europe through 3D semantic modelling proposes a workflow aimed at the achievements of efficient 3D digitization methods, post-processing tools for an enriched semantic modelling, web-based solutions and applications to ensure a wide access to experts and non-experts. In order to face these challenges and to start solving the issue of the large amount of captured data and time-consuming processes in the production of 3D digital models, an Optimized Data Acquisition Protocol (DAP) has been set up. The purpose is to guide the processes of digitization of cultural heritage, respecting needs, requirements and specificities of cultural assets.

EXTENDING THE LIFE OF VIRTUAL HERITAGE: REUSE OF TLS POINT CLOUDS IN
SYNTHETIC STEREOSCOPIC SPHERICAL IMAGES
Authors: Garcia Fernandez J. , Tammi K. , Joutsiniemi A.
Published: February 2017

Abstract. Recent advances in Terrestrial Laser Scanner (TLS), in terms of cost and flexibility, have consolidated this technology as an essential tool for the documentation and digitalization of Cultural Heritage. However, once the TLS data is used, it basically remains stored and left to waste.How can highly accurate and dense point clouds (of the built heritage) be processed for its reuse, especially to engage a broader audience? This paper aims to answer this question by a channel that minimizes the need for expert knowledge, while enhancing the interactivity with the as-built digital data: Virtual Heritage Dissemination through the production of VR content. Driven by the ProDigiOUs project’s guidelines on data dissemination (EU funded), this paper advances in a production path to transform the point cloud into virtual stereoscopic spherical images, taking into account the different visual features that produce depth perception, and especially those prompting visual fatigue while experiencing the VR content. Finally, we present the results of the Hiedanranta’s scans transformed into stereoscopic spherical animations.

Abstract. The paper describes the used of close-range photogrammetry and terrestrial laser scanning technologies as an innovative technology for acquiring the three-dimensional data of an ancient cave paintings. The close-range photogrammetry technology used in the research was divided in two categories which are the UAV-based close-range photogrammetry and the terrestrialbased close-range photogrammetry. The UAV-based technology involved with the used of calibrated Phantom 4 System while the terrestrial-based technology involved with the calibrated Sony F828 digital camera and pPhotoModeler software. Both stereo and convergent image acquisition techniques were used to acquire the images of the paintings. The ancient cave paintings were also recorded using terrestrial laser scanning technology. In the research, the FARO Focus 3D terrestrial laser scanner was used to capture the three-dimensional point clouds and images of the paintings. The finding shows that both close-range photogrammetry and laser scanning technologies provide excellent solutions to map and to record the ancient paintings. As compared to the conventional method, both close-range photogrammetry and terrestrial laser scanning technology provide a noncontact solution for data acquisition and the data was recorded in digital format for better protection and security.

Abstract. In recent decades, 3D reconstruction has progressively become a tool to show archaeological and architectural monuments in their current state, presumed past aspect and to predict their future evolution. The 3D representations trough time can be useful in order to study and preserve the memory of Cultural Heritage and to plan maintenance and promotion of the historical sites. This paper represent a case study, at architectonic and urbanistic scale, based on methodological approach for CH time-varying representations proposed by JPI-CH European Project called Cultural Heritage Through Time (CHT2). The work is focused on the area of Milan Roman circus, relatively to which was conducted both a thorough philological research based on several sources and a 3D survey campaign of still accessible remains, aiming at obtaining the monumental representation of the area in 3 different ages.

Abstract. During the last two decades we have witnessed great improvements in ICT hardware and software technologies. Three-dimensional content is starting to become commonplace now in many applications. Although for many years 3D technologies have been used in the generation of assets by researchers and experts, nowadays these tools are starting to become commercially available to every citizen. This is especially the case for smartphones, that are powerful enough and sufficiently widespread to perform a huge variety of activities (e.g. paying, calling, communication, photography, navigation, localization, etc.), including just very recently the possibility of running 3D reconstruction pipelines. The REPLICATE project is tackling this particular issue, and it has an ambitious vision to enable ubiquitous 3D creativity via the development of tools for mobile 3D-assets generation on smartphones/tablets. This article presents the REPLICATE project’s concept and some of the ongoing activities, with particular attention being paid to advances made in the first year of work. Thus the article focuses on the system architecture definition, selection of optimal frames for 3D cloud reconstruction, automated generation of sparse and dense point clouds, mesh modelling techniques and post-processing actions. Experiments so far were concentrated on indoor objects and some simple heritage artefacts, however, in the long term we will be targeting a larger variety of scenarios and communities.
3D MODELLING WITH THE SAMSUNG GEAR 360

Abstract. The Samsung Gear 360 is a consumer grade spherical camera able to capture photos and videos. The aim of this work is to test the metric accuracy and the level of detail achievable with the Samsung Gear 360 coupled with digital modelling techniques based on photogrammetry/computer vision algorithms. Results demonstrate that the direct use of the projection generated inside the mobile phone or with Gear 360 Action Direction (the desktop software for post-processing) have a relatively low metric accuracy. As results were in contrast with the accuracy achieved by using the original fisheye images (front and rear facing images) in photogrammetric reconstructions, an alternative solution to generate the equirectangular projections was developed. A calibration aimed at understanding the intrinsic parameters of the two lenses camera, as well as their relative orientation, allowed one to generate new equirectangular projections from which a significant improvement of geometric accuracy has been achieved.

Abstract. The correct derivation of paleotemperatures from ice cores requires exact knowledge of all processes involved before and after the deposition of snow and consecutive formation of ice. At the Antarctic deep ice core drilling site Dome C, a unique data set of daily precipitation amount, type and stable water isotope ratios is available that enables us to study atmospheric processes that influence the stable water isotope ratio of precipitation in detail. Meteorological data from both automatic weather station and a mesoscale atmospheric model were used to investigate how different atmospheric flow patterns determine the precipitation parameters. A classification of synoptic situations that cause precipitation at Dome C was established and, together with back-trajectory calculations, was utilized to estimate moisture source areas. With the resulting source area conditions (wind speed, sea surface temperature (SST) and relative humidity) as input, the precipitation stable isotopic composition was modelled using the so-called Mixed Cloud Isotope Model (MCIM). The model generally underestimates the depletion of 18O in precipitation. It was shown that, contrary to the assumption widely used in ice core studies, a more northern moisture source does not necessarily mean stronger isotopic fractionation. This is due to the fact that snowfall events at Dome C are often associated with warm air advection due to amplification of planetary waves, which considerably increases the site temperature and thus reduces the temperature difference between source area and deposition site. Also, no correlation was found between relative humidity at the moisture source and the deuterium excess in precipitation. The significant difference in the isotopic signal of hoar frost and diamond dust was shown to disappear after removal of seasonality.
La coordinación entre la responsabilidad concursal y la responsabilidad societaria en Derecho español
Authors: Morales Barceló Judith
Published: February 2017

La convivencia en Derecho español de un régimen de responsabilidad societaria y un régimen de responsabilidad concursal exigible a los administradores de sociedades mercantiles, genera ciertas dudas cuando éstas se encuentran incursas en un procedimiento concursal. En este artículo se van a analizar las diferentes posturas doctrinales y jurisprudencias sobre los efectos del procedimiento concursal en la responsabilidad por deudas ex artículo 367 de la Ley de Sociedades de Capital y en la responsabilidad por daños ex artículos 238 y 241 de la misma Ley. Así mismo, se va a analizar la posible coordinación de estas responsabilidades con la responsabilidad concursal, exigible en supuestos en los que una sociedad mercantil se encuentre en situación de insolvencia.
Meticulous Depiction and Genetic Mechanism of Unconformity Belt Structure

Published: February 2017

Current research on unconformity belt mainly concentrates on the analysis and description of unconformity surface and contact relationship with overlying and underlying strata. Too much emphasis on the division of the “three-layer structure” of unconformity yields obvious disadvantages, i.e., that studies are not only insufficient in the authenticity of architecture but also in the characterization of the combination of the two- and three-dimensional perspectives. Thus, the analysis of genetic mechanism and meticulous depiction is ignored. Accordingly, by making full use of the outcrops and combining previous research findings, this study aims to provide a detailed description and analysis for the unconformity belt structure, and points out the non-uniqueness of the three-layer structure of the unconformity belt. Based on the theory of depositional process and according to the method and principle of the “point-line-surface”, a comprehensive characterization method combined with a kind of “two-dimensional structure” and “three-dimensional structure” is proposed. A two-dimensional structure is a kind of surface structure, while the three-dimensional structure is a kind of body structure, Moreover, this study discusses the recognition significance of the visual unconformity line and visual unconformity surface with respect to the unconformity belt structure. According to the spatial allocation and geological significance of the unconformity belt, two types of models are established in order to depict the structure of unconformity belt better. Combined with the structural elements of the unconformity belt and complied from the viewpoint of the sedimentary environment, the formation mechanism of two-and three-dimensional structures is summarized.

Published: February 2017

The eLearning industry has grown rapidly in recent years, and as a result in the context of higher education there is significant interest in implementing and managing eLearning through Learning Management Systems (LMS). This study uses the Technology Acceptance Model (TAM) to test faculty members’ acceptance of a new LMS using structural equation modeling (SEM). In addition, the study extends the model by incorporating two external factors: training programs on the new LMS conducted prior to implementation and organizational support for the new LMS. Each of these two factors is generally believed to have a significant impact on the acceptance of a new LMS on the part of faculty members. The results of this study validate the use of TAM in the context of higher education. Further, our findings affirm the importance of providing training in regard to the LMS before implementation and likewise the importance of providing organizational support.
