Proactive spectrum sharing incentive for physical layer security enhancement using outdated CSI
( Institute of Electrical and Electronics Engineers Inc. , 2016 , Article)We investigate the spectrum sharing possibility as an incentive to enhancing the physical layer security. The concept behind this is that a legitimate source-destination pair, communicating in the presence of a passive ... -
Proactive Video Chunks Caching and Processing for Latency and Cost Minimization in Edge Networks
( Institute of Electrical and Electronics Engineers Inc. , 2019 , Conference Paper)Recently, the growing demand for rich multimedia content such as Video on Demand (VoD) has made the data transmission from content delivery networks (CDN) to end-users quite challenging. Edge networks have been proposed ... -
Proatherogenic sialidases and desialylated lipoproteins: 35 years of research and current state from bench to bedside
( Multidisciplinary Digital Publishing Institute (MDPI) , 2021 , Article)This review summarizes the main achievements in basic and clinical research of atheroscle-rosis. Focusing on desialylation as the first and the most important reaction of proatherogenic pathological cascade, we speak of ... -
Probabilistic analysis of fatigue life for asphalt mixtures using the viscoelastic continuum damage approach
( Elsevier Ltd , 2016 , Article)Fatigue cracking is one of the most serious distress modes affecting the serviceability of asphalt pavement structures. The inherent variability of asphaltic materials exhibited in fatigue test results, especially for ... -
Probabilistic band-splitting for a buffered cooperative cognitive terminal
( Institute of Electrical and Electronics Engineers Inc. , 2014 , Conference Paper)In this paper, we propose a cognitive protocol that involves cooperation between the primary and secondary users. In addition to its own queue, the secondary user (SU) has a queue to store, and then relay, the undelivered ... -
Probabilistic human health risk assessment of trace elements in ballast water treated by reverse osmosis desalination plants
( Elsevier , 2023 , Article)Very few studies have paid attention to the transport of heavy and toxic metals via ballast water coming from different countries of the world. In the present study, ballast water samples (n = 83) were collected from ships, ... -
Probabilistic Integration of Demand Flexibilities in a Renewable Energy-Assisted Community Network
( Institute of Electrical and Electronics Engineers Inc. , 2023 , Conference Paper)This paper proposes a novel decision-making tool aiding community operators in optimally procuring their energy needs from available supply sources while incorporating potential demand-side flexibilities. The supply sources ... -
