360-Attack: Distortion-Aware Perturbations from Perspective-Views
(2022)The application of deep neural networks (DNNs) on 360-degree images has achieved remarkable progress in the recent years. However, DNNs have been demonstrated to be vulnerable to well-crafted adversarial examples, which ... -
360-Degree VR Video Watermarking Based on Spherical Wavelet Transform
(2021)Similar to conventional video, the increasingly popular 360 virtual reality (VR) video requires copyright protection mechanisms. The classic approach for copyright protection is the introduction of a digital watermark into ... -
3D Co-N-doped hollow carbon spheres as excellent bifunctional electrocatalysts for oxygen reduction reaction and oxygen evolution reaction
(2017)Non-precious materials have been considered as promising bifunctional catalysts towards oxygen reduction reaction (ORR) and oxygen evolution reaction (OER). In the present work, a three dimensional (3D) Co-N co-doped hollow ... -
The effect of gravitational acceleration in the streaming potential on the surface of a planetary body and in orbit around it
(2015)A corrected gravitational acceleration has been used for the study of the electric streaming potential. The acceleration has been corrected for the oblateness of a spherical body, as well as the rotational velocity of the ... -
Environmental behavior in a private-sphere context: Integrating theories of planned behavior and value belief norm, self-identity and habit
(2019)This study explores the determinants of environmental behavior in a private-sphere context and proposes an integrative model that includes the constructs from two theoretical frameworks, the theory of planned behavior (TPB) ... -
Gas mixing and final mixture composition control in simple geometry micro-mixers via DSMC analysis
(2019)The mixing process of two pressure driven steady-state rarefied gas streams flowing between two parallel plates was investigated via DSMC (Direct Simulation Monte Carlo) for different combinations of gases. The distance ... -
Improved Face Detector on Fisheye Images via Spherical-Domain Attention
(2021)As one type of omnidirectional projection, fisheye images have been widely used in automatic driving and visual surveillance. However, they cannot be processed well by the traditional algorithms designed for the planar ... -
Microrotation viscosity effect on turbulent micropolar fluid channel flow
(2021)Fluids with an internal rigid microstructure, the so-called micropolar fluids, gain significant attention in many industrial, natural, and biological systems. Here, we study in detail the microrotation viscosity effect on ... -
Towards sustainable planning in the era of climate change: Spatial policies for built-up areas in Greece
(2011)This paper is a critical approach of the institutional framework and the related policies to environmental planning in contemporary Greek towns. Specifically, the paper investigates the achievements as well as the malfunctions ...
