Cognitive relay-sharing by using hierarchical modulation under interference constraints
( Institute of Electrical and Electronics Engineers Inc. , 2014 , Conference Paper)In this paper, we investigate relay-sharing in cognitive radio (CR) networks to improve the secondary user's (SU's) performance in the presence of interference. It is assumed that the relay is shared simultaneously between ... -
Cognitive relaying in wireless sensor networks: Performance analysis and optimization
( IEEE , 2010 , Conference Paper)The anticipated increase in the density of the deployed wireless sensor networks calls for spectrum sharing through unlicensed access to licensed spectrum. The key technology for spectrum sharing in this scenario is cognitive ... -
Cognitive status and sleep quality can explain the fear of falling and fall history in people with Parkinson's disease.
( Lippincott, Williams & Wilkins , 2023 , Article)Fear of falling (FOF) is highly prevalent in people with Parkinson's disease (PwPD) and contributes to high fall risk. Studies reporting on the relationship between falls, FOF, and non-motor factors such as cognitive ... -
Cognitive technology for children with hearing impairments
( IEEE Computer Society , 2016 , Conference Paper)Lack of specialists, speech instructors and sign language instructors in the Arab world have led to the impediment of the education and cognitive development for children with Hearing Impairments (HI). The objective of ... -
Cognitive Theory of Mind Influences Destination Memory: Evidence from Normal Aging and Alzheimer's Disease
( Oxford University Press , 2019 , Article)Objective: Theory of mind and destination memory are social abilities that require processing the attributes of interlocutors. Empirical research has demonstrated a relationship between performance on both abilities in ... -
Cognitive transmission based on data priority classification in WSNs for Smart Grid
(2012 , Conference Paper)Smart Grid integrates digital processing, sensor technology, automatic control and communication to the traditional power grid to achieve more efficient electricity distribution and management. Applying wireless sensor ... -
Cognitive, affective and conative domains of sustainable consumption: Scale development and validation using confirmatory composite analysis
( MDPI , 2020 , Article)This study aims to conceptualise, develop, purify and validate a multiple-item scale to measure a sustainable consumption (SC) construct from the perspective of developing countries, particularly Malaysia. Interview, a ... -
A Cognizance of Green Bond Features Preferential to Renewable Energy Project Financing in Ghana
( IEEE , 2021 , Article)Issuance of green bonds (GBs) is valuable for developing countries because it provides a market deepening mechanism, which enables greater liquidity for investments in renewable energy (RE) sector. This article is premised ... -
