In this work, we examine the performance, energy efficiency, and usability when using Python for developing high-performance computing codes running on the graphics processing unit (GPU). We investigate the portability of ...

Quasi-stationary oscillations in game-driven evolutionary dynamics

Vershinina, Olga; Ivanchenko, Mikhail; Denysov, Sergiy (IPME, 2019-12-24)

Nonlinear dynamics makes use of attactors to describe asymptotic behavior of complex systems. However, in real life can be unattainable, as achieving them might require time much exceeding all relevant timescales of a ...

Conceptualizing universal design for the information society through a universal human rights lens

Giannoumis, G. Anthony; Stein, Michael Ashley (Brill Academic Publishers, 2019-06-03)

Universal Design aims to ensure that everyone can equally use products, environments, programs, and services. This article examines the theoretical underpinnings and potential application of universal design by exploring ...

A Usability Evaluation of Web User Interface Scrolling Types

Murano, Pietro; Sharma, Sushil (University of Illinois at Chicago Library, 2020)

This paper details a usability evaluation of scrolling techniques on Web sites. The scrolling methods evaluated were normal scrolling (with default pagination), infinite scrolling, infinite scrolling with a load more button ...

Multistable Technologies and Pedagogy for Resilience: A Postphenomenological Case Study of Learning by 3D printing

Pavel, Nenad; Medola, Fausto Orsl; Berg, Arild; Brevik, Birger (The Design and Technology Association, 2020)

Accelerated technological innovation induces disruptions in society and education. It results in both threats to and opportunities for the way the society learns and works. This case study examined the phenomenon of learning ...

Method to Obtain Neuromorphic Reservoir Networks from Images of in Vitro Cortical Networks

Mello, Gustavo; Pontes-Filho, Sidney; Sandvig, Ioanna; Valderhaug, Vibeke Devold; Zouganeli, Evi; Huse Ramstad, Ola; Sandvig, Axel; Nichele, Stefano (2020-02-20)

In the brain, the structure of a network of neurons defines how these neurons implement the computations that underlie the mind and the behavior of animals and humans. Provided that we can describe the network of neurons ...

Enhancing Security of Cellular IoT with Identity Federation

Santos, Bernardo; Dzogovic, Bruno; Feng, Boning; Do, Thuan Van; Jacot, Niels; Do, van Thanh (Springer, 2019-08-15)

This paper presents a Cellular Identity Federation solution which both strengthens and simplifies the authentication of Internet of Things (IoT) devices and applications by providing single sign-on between the network ...

Implementation of Building Information modeling in Vietnamese infrastructure construction: A case study of institutional influences on a bridge project

Bui, Nam (Wiley Online Library, 2019-11-18)

Many of today's building designs are created based on three‐dimensional modeling technology. Architects and engineers use so‐called building information modeling (BIM) systems to create digital representations of buildings. ...

Assessment and manipulation of the computational capacity of in vitro neuronal networks through criticality in neuronal avalanches
