The Gaia-ESO Survey: Chromospheric emission, accretion properties, and rotation in gamma Velorum and Chamaeleon

2015

Aims: One of the goals of the Gaia-ESO Survey (GES), which is conducted with FLAMES at the VLT, is the census and the characterization of the low-mass members of very young clusters and associations. We conduct a comparative study of the main properties of the sources belonging to γ Velorum (γ Vel) and Chamaeleon I (Cha I) young associations, focusing on their rotation, chromospheric radiative losses, and accretion. Methods: We used the fundamental parameters (effective temperature, surface gravity, lithium abundance, and radial velocity) delivered by the GES consortium in the first internal data release to select the members of γ Vel and Cha I among the UVES and GIRAFFE spectroscopic obser…

Sex differences in mate preferences across 45 countries: a large-scale replication

2020

Considerable research has examined human mate preferences across cultures, finding universal sex differences in preferences for attractiveness and resources as well as sources of systematic cultural variation. Two competing perspectives-an evolutionary psychological perspective and a biosocial role perspective-offer alternative explanations for these findings. However, the original data on which each perspective relies are decades old, and the literature is fraught with conflicting methods, analyses, results, and conclusions. Using a new 45-country sample (N = 14,399), we attempted to replicate classic studies and test both the evolutionary and biosocial role perspectives. Support for unive…

Verso una dimensione narrativa delle mappe

2021

Tra il pensiero e la costruzione dell’architettura il disegno ha un ruolo baricentrico per connettere i diversi protagonisti di una realizzazione e per coinvolgere la collettività facendo percepire inedite prospettive. La scrittura si rivela utile per esplicitare ciò che nella grafica è sotteso e per stabilire un ordine nuovo nel ragionamento progettuale. I rapporti fra segni e significati si moltiplicano nei sistemi informativi recenti in cui si ha la sensazione di poter dire moltissimo (dati numerici e spaziali) ma a volte sfugge quella sintesi indispensabile per una interpretazione concreta, finalizzata alla costruzione di possibili esperienze fisiche. Per l’esplorazione dell’uso di dive…

Between the idea and the construction of the architecture the drawing plays a central role to connect the different protagonists of a project. It involves the community by envisaging unprecedented perspectives. Writing is useful to explicit the graphics and establish a new order in the design reasoning. The relationships between signs and meanings multiply in recent information systems in which it seems possible to conclude a lot (thanks to numerical and spatial data) but sometimes a synthesis is missing though that synthesis is fundamental to create new physical experiences. For the exploration of the use of different architectural languages and for the push towards the project rather than a sterile cataloging the case of the Piano Programma for the historic center of Palermo (Giuseppe Samonà Giancarlo De Carlo Umberto Di Cristina Anna Maria Sciarra Borzí 1979-82) reveals to be ambitious. Giuseppe Samonà integrates the classical representation based on Monge's projections with photographs and iconic drawings associating signs with a linguistic-structural communication capable of expressing the relationships between the parts at the basis of a morphological approach to the plan. The graphic story ("second language") of the urban fabric has creative implications expressed by images and annotations ("first language") useful for decoding them. Since the plan focuses on the potential of a storytelling that orients the imagination of its readers (designers citizens politicians) it can contribute to the study titled "B4R– BRANDING 4 RESILIENCE - Tourist infrastructure as a tool to enhance small villages by drawing resilient communities and new open habitats” as a starting point for the mapping in which GIS analysis and multidisciplinary data (geometric topological and quantitative) relating to some villages of the internal Sicily shall translate into a new architectural urban and landscape quality.Settore ICAR/14 - Composizione Architettonica E Urbana

Integración de una base de datos de procedencias en el entorno MARC y de datos enlazados: el caso de la Biblioteca Nacional de España

2022

En este artículo se presenta, a grandes rasgos, el trabajo llevado a cabo durante los últimos años en la Biblioteca Nacional de España, para normalizar e integrar la información de antiguos poseedores en su catálogo automatizado, adaptando la información de procedencias al formato MARC, y desde ahí, darle salida a través del ecosistema de datos enlazados de la biblioteca, a un entorno más dinámico que permite ofrecer un buscador especializado en el portal datos.bne.es

Entanglement dynamics in superconducting qubits affected by local bistable impurities

2012

We study the entanglement dynamics for two independent superconducting qubits each affected by a bistable impurity generating random telegraph noise (RTN) at pure dephasing. The relevant parameter is the ratio $g$ between qubit-RTN coupling strength and RTN switching rate, that captures the physics of the crossover between Markovian and non-Markovian features of the dynamics. For identical qubit-RTN subsystems, a threshold value $g_\mathrm{th}$ of the crossover parameter separates exponential decay and onset of revivals; different qualitative behaviors also show up by changing the initial conditions of the RTN. We moreover show that, for different qubit-RTN subsystems, when both qubits are …

Tirdzniecības atvērtības ietekme uz ekonomikas izaugsmi, CAE valstu empīriskais pētījums

2021

Darba mērķis ir izpētīt tirdzniecības atvērtības ietekmi uz ekonomikas izaugsmi, izmantojot 16 Centrālās un Austrumeiropas valstu paneļa datus 2010. – 2019. gadā, salīdzinot 4 dažādus tirdzniecības atvērtības rādītājus. Apvienotie OLS un fiksētie efekti tiek izmantoti kā primārie novērtētāji, un noturības analīzei tiek izmantots sistēmas GMM tests. Apkopoto OLS un fiksēto šķērsgriezumu regresiju iegūtie rezultāti parāda, ka dažādos tirdzniecības atvērtības mērījumos tirdzniecības atvērtība pozitīvi un ļoti nozīmīgi ietekmē ekonomikas izaugsmi. GMM sistēmas testi parāda tirdzniecības atvērtības negatīvo ietekmi uz ekonomikas izaugsmi, bet nozīmīgumu ieguva tikai divi atvērtības rādītāji.

A More Simple G-Code Programming within an Open Source CNC System

2006

In this paper we introduce the utilization of a new CNC programming language, named O-Word, a way to implement several branching routines into the EMC interpreter. It opens new interesting possibilities to programmers who can build subroutines, loops, and conditionals while taking advantage of the interpreter's use of variables and computation. Therefore, it allows us to make pieces describing theirs features instead of tool's movements. We will demonstrate a new complex routine in order to show both the language syntax and its potential for advanced applications.

INTERNET BASED DEVELOPMENT OF AN OPEN SOURCE LOW-COST CNC

2006

In this paper we show how to realize a low-cost numerical system, based on an “open source” software called EMC (Enhanced Machine Control). First, we assembled a low cost CNC workstation with a remote control by means of an online computer with a webcam, as an example of the software's potentiality. Moreover, we translated a graphical user interface (AXIS), in co-operation with the international development community, in order to improve its userfriendliness.

A Web based remote control of CNC machines

2009

Due to the large variety of products in small batch sizes, a modern machining shop floor requires an advanced real-time control system able to both monitor all the features and adapt the manufacturing system to the rapid changes of production capability and functionality. This is especially true when the shop floors are combined with the e-Manufacturing concept. e-Manufacturing is a transformation system which enables the manufacturing operations to achieve a predictive near-zero-downtime performance as well as to synchronize with the management systems through the use of infotronics technologies (i.e., wireless connections, web applications, networking systems, etc.). In recent years, the …
