Data Science na modelação e previsão de séries económico-financeiras: das metodologias clássicas ao Deep Learning
See10071/22964A articulação de técnicas/ferramentas estatísticas, matemáticas e computacionais, no processo de análise, modelação e previsão de séries temporais, manifesta-se um claro suporte de apoio à tomada de decisão. O constante desafio na procura de previsões acuradas tem levado os investigadores à&...

Motives, frequency and attitudes toward emoji and emoticon use
See10071/22963Electronic Mediated Communication (EMC) has become highly prevalent in our daily lives. Many of the communication formats used in EMC are text-based (e.g., instant messaging), and users often include visual paralinguistic cues in their messages. In the current study, we examined the usa...

The citizen drone: protest, sousveillance and droneviewing
See10071/22962In this article we will discuss the use of drones, as well as the visual simulation of drone afforded aesthetics, by activists, artists and protesters. We use the existing literature of surveillance studies and visual studies to examine how exactly a drone-afforded visibility emerg...

A precoding aided space domain index modulation scheme for downlink multiuser MIMO systems
See10071/22961In this correspondence, we propose a space domain index modulation (IM) scheme for the downlink of multiuser multiple-input multiple-output (MU-MIMO) systems. Instead of the most common approach where spatial bits select active receiver antennas, in the presented scheme the spatial information&#x...

Complex (super)-matrix models with external sources and q-ensembles of Chern–Simons and ABJ(M) type
See10071/22960The Langmann–Szabo–Zarembo (LSZ) matrix model is a complex matrix model with a quartic interaction and two external matrices. The model appears in the study of a scalar field theory on the non-commutative plane. We prove that the LSZ matrix model computes the probability of at...
