Knowledge acquisition in science and the blurred boundary between perception and cognition
British Educational Research Journal, EarlyView.Abstract This paper provides a critical and detailed study of what researchers in the fields of contemporary cognition and neuroscience have revealed about the blurred boundary between perception and cognition. We set out the arguments with a view to what researchers and teachers should now consider regarding the subtleties of their interrelationship ...

Prospects and challenges of Metaverse application in data‐driven intelligent transportation systems
IET Intelligent Transport Systems, Volume 17, Issue 1, Page 1-21, January 2023., 2023 Abstract The Metaverse is a concept used to refer to a virtual world that exists in parallel to the physical world. It has grown from a conceptual level to having real applications in virtual reality games. The applicability of the Metaverse in numerous sectors like marketing, education, social, and even advertising exists. However, there exists little

Spacecraft Charging and Hazards to Electronics in Space [PDF]
arXiv, 2009 The interaction of a space system with its orbital environment is a major consideration in the design of any space system, since a variety of hazards are associated with the operation of spacecraft in the harsh space environment. In this brief review, two types of hazards to Earth-orbiting spacecraft are discussed: spacecraft charging and radiation ...

Securing the Inter-Spacecraft Links: Doppler Frequency Shift based Physical Layer Key Generation [PDF]
arXiv, 2020 We propose a novel physical layer secret key generation method for the inter-spacecraft communication links. By exploiting the Doppler frequency shifts of the reciprocal spacecraft links as a unique secrecy source, spacecrafts aim to obtain identical secret keys from their individual observations.

Neutrino Propulsion for Interstellar Spacecraft [PDF]
J.Br.Interplanet.Soc. 52 (1999) 424, 1998 An exotic spacecraft propulsion technology is described which exploits parity violation in weak interactions. Anisotropic neutrino emission from a polarized assembly of weakly interacting particles converts rest mass directly to spacecraft impulse.

Investigating the Magnetic Structure of Interplanetary Coronal Mass Ejections using Simultaneous Multi-Spacecraft In situ Measurements [PDF]
arXiv, 2023 In situ measurements from spacecraft typically provide a time series at a single location through coronal mass ejections (CMEs) and they have been one of the main methods to investigate CMEs. CME properties derived from these in situ measurements are affected by temporal changes that occur as the CME passes over the spacecraft, such as radial expansion

Corporate Social Responsibility and Environmental Management, EarlyView.ABSTRACT Accurate reporting on the sustainability of business value propositions must be supported by reliable data sources and sound methodologies such as life cycle assessment (LCA). Showing commitment to more responsible activity without quantifying business impacts, or quantifying them only partially, could fall into greenwashing practices.
