( Elsevier , 2021 , Article)The UN COP26 2021 conference on climate change offers the chance for world leaders to take action and make urgent and meaningful commitments to reducing emissions and limit global temperatures to 1.5 °C above pre-industrial ... -
A COMPREHENSIVE FRAMEWORK FOR DESIGN AND EVALUATION OF M-LEARNING APPLICATIONS
(2016 , Master Thesis)Human-computer interaction (HCI) communities and Mobile Learning Communities (MLCs) are well aware of the challenges that mobile devices impose when it comes to conducting proper usability and user experience evaluations ... -
Consumer Acceptance and Use of Information Technology: A Meta-Analytic Evaluation of UTAUT2
( Springer Nature , 2020 , Article)Despite being regarded as the most comprehensive theory in understanding individual technology adoption – UTAUT2 theory with growing number of citations and impetus beyond IS domain face strong criticism on usage of the ... -
Cooperative communications scheme with interference management under ICI for OFDM LTE-A systems
( IEEE Computer Society , 2013 , Conference Paper)In long term evolution (LTE) systems, the achievable cell spectral efficiency is often limited by the inter carrier interference (ICI) or coverage shortage of base stations. Hence, in LTE-Advanced, cooperative communication ... -
Establishing trust in cloud computing
( IEEE Computer Society , 2010 , Article)How can cloud providers earn their customers' trust when a third party is processing sensitive data in a remote machine located in various countries? Emerging technologies can help address the challenges of trust in cloud ... -

On the detection and estimation of correlated signal using circular antenna arrays
( IEEE , 2011 , Conference Paper)This paper presents the design and analysis of smart antenna systems used for the detection and estimation of correlated radio signals encountered in multipath environments using circular antenna arrays. The MUSIC algorithm ... -
Performance analysis of relay selection schemes in underlay cognitive networks with imperfect channel state information
( IEEE Computer Society , 2013 , Conference Paper)Cognitive Radio (CR) aims to improve spectrum utilization by allowing unlicensed users to access the licensed spectrum and to coexist with primary user (PU) while respecting the PU's restrictions. An interesting case to ... -
Power loading algorithms for SEC diversity schemes
( IEEE , 2007 , Conference Paper)Switch and Examine Combing (SEC) diversity scheme is one of the simplest diversity schemes to combat fading. When the power used for probing the channels in this scheme is fixed, it can be higher than what is actually ... -
Relay selection for cooperative underwater acoustic communication systems
( IEEE , 2012 , Conference Paper)In this paper, we consider a multi-carrier and multi-relay underwater acoustic communication (UWAC) system and investigate the relay selection problem. Our channel model is built on an aggregation of both large-scale path ... -
