A Novel Optimization for GPU Mining Using Overclocking and Undervolting
2022
Cryptography and associated technologies have existed for a long time. This field is advancing at a remarkable speed. Since the inception of its initial application, blockchain has come a long way. Bitcoin is a cryptocurrency based on blockchain, also known as distributed ledger technology (DLT). The most well-known cryptocurrency for everyday use is Bitcoin, which debuted in 2008. Its success ushered in a digital revolution, and it currently provides security, decentralization, and a reliable data transport and storage mechanism to various industries and companies. Governments and developing enterprises seeking a competitive edge have expressed interest in Bitcoin and other cryptocurrencie…
$PT$-symmetric graphene under a magnetic field
2016
We propose a $PT$-symmetrically deformed version of the graphene tight-binding model under a magnetic field. We analyze the structure of the spectra and the eigenvectors of the Hamiltonians around the $K$ and $K'$ points, both in the $PT$-symmetric and $PT$-broken regions. In particular we show that the presence of the deformation parameter $V$ produces several interesting consequences, including the asymmetry of the zero-energy states of the Hamiltonians and the breakdown of the completeness of the eigenvector sets. We also discuss the biorthogonality of the eigenvectors, which {turns out to be} different in the $PT$-symmetric and $PT$-broken regions.
Identity | The colors of project
2017
“Identity | The Colors of Project” è il primo Convegno Internazionale organizzato da 110eLab, Associazione Culturale per la promozione del design siciliano, con la collaborazione dell’INBAR | Sezione Trapani. L’obiettivo, nel quadro del Piano Colore Isole Egadi, è di analizzare la costruzione dell’identità attraverso una strategia sapientemente progettata. Ciò può essere brand, di aziende come di enti, dunque immagine coordinata (marchio, carattere tipografico, gamma cromatica...), oppure una campagna fotografica o ancora una qualità visiva che emerge grazie all’impiego di segni distintivi che fanno sistema. L’attenzione soprattutto è rivolta alla qualità, non soltanto visiva, che definisce…
From detail to project: House Caiozzo-Facciola
2021
The analysis and understanding, through drawing, of Casa Cajozzo-Facciolà, designed by Pasquale Culotta and Giuseppe Leone, in 1979, on a cliff in Contrada Ogliastrillo in Cefalù, followed a pro- cess that is unlike the traditional process. From the consideration that the detail is thought of as a portion of a whole, which allows, through a close examination, to re-read the global system from which it was provisionally extracted, we proceeded with the analysis of the expected construction system, the balloon frame, and thanks to a close examination of the construction details of which there were sketches with explanatory notes, the proportions, spaces, volumes, surface treatment of the over…
Le roman graphique en méthodologie CLIL
2018
L’article se propose de cerner les applications du roman graphique dans les modules CLIL (Content and Language Integrated Learning) en analysant les aspects principaux de cette méthodologie, l’importance des documents authentiques et l’organisation des modules de formation. Les caractéristiques présentes dans les romans graphiques « On les aura ! » de Barroux et « Putain de guerre » de Tardi et Verney seront mises en évidence pour tracer un module didactique d’histoire et langue française. L’articolo si propone di individuare le applicazioni del romanzo grafico nei moduli CLIL (Content and Language Integrated Learning) analizzando i principali aspetti di questa metodologia, l’importanza del…
A Dataset of Annotated Omnidirectional Videos for Distancing Applications
2021
Omnidirectional (or 360°) cameras are acquisition devices that, in the next few years, could have a big impact on video surveillance applications, research, and industry, as they can record a spherical view of a whole environment from every perspective. This paper presents two new contributions to the research community: the CVIP360 dataset, an annotated dataset of 360° videos for distancing applications, and a new method to estimate the distances of objects in a scene from a single 360° image. The CVIP360 dataset includes 16 videos acquired outdoors and indoors, annotated by adding information about the pedestrians in the scene (bounding boxes) and the distances to the camera of some point…
Economic specialization and diversification at the country and regional level: introducing a conceptual framework to study innovation policy logics
2018
While there has been a shared understanding that innovation policy is about rendering institutional change, there has been an emerging interest in identifying the institutional logics underlying in...
A scalable multiagent system architecture for interactive applications
2013
Interactive applications like crowd simulations need to properly render the virtual world while simulating the interaction of thousands of agents at the same time. The computational workload generated by these two tasks highly increases with the number of the simulated agents, requiring a scalable design of the multiagent system. In this paper, we present, in an unified manner, a distributed multiagent system architecture that can manage large crowds of autonomous agents at interactive rates while rendering multiple views of the virtual world being simulated. This architecture consists of a distributed multiagent system and a complementary distributed visualization subsystem. We also presen…
A distributed visualization system for crowd simulations1
2011
The visualization system of large-scale crowd simulations should scale up with both the number of visuals views of the virtual world and the number of agents displayed in each visual. Otherwise, we could have large scale crowd simulations where only a small percentage of the population is displayed. Several approaches have been proposed in order to efficiently render crowds of animated characters. However, these approaches either render crowds animated with simple behaviors or they can only support a few hundreds of user-driven entities. In this paper, we propose a distributed visualization system for large crowds of autonomous agents that allows the visualization of crowds animated with co…
Computational procedures for plastic shakedown design of structures
2004
The minimum volume design problem of elastic perfectly plastic finite element structures subjected to a combination of fixed and perfect cyclic loads is studied. The design problem is formulated in such a way that incremental collapse is certainly prevented. The search for the structural design with the required limit behaviour is effected following two different formulations, both developed on the grounds of a statical approach: the first one operates below the elastic shakedown limit and is able to provide a suboptimal design; the second one operates above the elastic shakedown limit and is able to provide the/an optimal design. The Kuhn–Tucker conditions of the two problems provide usefu…
