Green Cognitive Radio (GCR) is a Cognitive Radio, which is aware of sustainable development and takes it as an additional constraint in the decision making function of the cognitive cycle. In this paper, we remind the Cognitive Radio concept, and then explain how the sensors distributed within the three layers of our model help to reach GCR. The use of these sensors, so as to make the correct d...

Abstract ERA5 reanalyses and observations of convective clouds precipitation are used over the northern Gulf Guinea between 7°W 3°E to study influence ocean surface temperature land–sea gradient on Coast rainfall (GCR) in boreal spring summer. Seasonal composites calculated around two dates indexing onset ( T ref ) demise end GCR. The date corresponds emergence equatorial upwelling spring, whic...

We present infrared and millimeter observations of molecular gas, dust and ionized gas towards a sample of clouds distributed along the 500 central pc of the Galaxy. The clouds were selected to investigate the physical state, in particular the high gas temperatures, of the Galactic center region (GCr) clouds located far from far-infrared of thermal radio continuum sources. We have found that th...

This study investigated attachment, maintenance behaviors, and stress in long distance (LDR) and geographically close (GCR) romantic relationships. Data was analyzed from participants (N = 473) who were in a serious romantic relationship and who completed two attachment measures, two maintenance behaviors measures, and a perceived global stress measure. A multivariate analysis of variance (MANO...

One major obstacle to human space exploration is the possible limitations imposed by the adverse effects of long-term exposure to the space environment. Even before human spaceflight began, the potentially brief exposure of astronauts to the very intense random solar energetic particle (SEP) events was of great concern. A new challenge appears in deep space exploration from exposure to the low-...

A short overview is presented of current issues concerning the production and evolution of Li, Be and B in the Milky Way. It is argued that the currently popular idea that Galactic Cosmic rays are accelerated inside metal-rich superbubbles (which leads “naturally” to the production of primary Be and B, as observed) encounters the same problems as the previously popular idea of supernovae accele...

Galactic cosmic rays (GCRs) are modulated by the heliospheric magnetic field (HMF) both over decadal time scales (due to long-term, global HMF variations), and over time scales of a few hours (associated with solar wind structures such as coronal mass ejections or the heliospheric current sheet, HCS). Due to the close association between the HCS, the streamer belt, and the band of slow solar wi...

Recently, Secure-Multiparty Computation (SMC) has been proposed as an approach to enable inter-domain network monitoring while protecting the data of individual ISPs. The SMC family includes many different techniques and variants, featuring different forms of ‘‘security’’, i.e., against different types of attack (er), and with different levels of computation complexity and communication overhea...
