A k-nearest neighbor multilabel ranking algorithm with application to content-based image retrieval
( Institute of Electrical and Electronics Engineers Inc. , 2017 , Conference)Multilabel ranking is an important machine learning task with many applications, such as content-based image retrieval (CBIR). However, when the number of labels is large, traditional algorithms are either infeasible or ... -
Vibration suppression in metastructures using zigzag inserts optimized by genetic algorithms
( Springer New York LLC , 2017 , Conference)Metastructures are known to provide considerable vibration attenuation for mechanical systems. With the optimization of the internal geometry of metastructures, the suppression performance of the host structure increases. ... -
Spatiotemporal saliency estimation by spectral foreground detection
( Institute of Electrical and Electronics Engineers Inc. , 2018 , Article)We present a novel approach for spatiotemporal saliency detection by optimizing a unified criterion of color contrast, motion contrast, appearance, and background cues. To this end, we first abstract the video by temporal ... -
Enabling ICT development with low cost high capacity wireless networks in remote and underdeveloped locations an application to public finance management in Comoros Islands
( Institute of Electrical and Electronics Engineers Inc. , 2014 , Conference)The 'Union of the Comoros' is a volcanic archipelago nation in the Indian Ocean, consisting of three islands. About half the population lives below the international poverty line of US$1.25 a day. The interiors of the ... -
Adaptive network coding for spectrum sharing systems
( Institute of Electrical and Electronics Engineers Inc. , 2015 , Conference)In this paper, we propose an adaptive network coding scheme for cognitive relay networks comprising multiple secondary sources communicating with a common destination in the presence of multiple primary users. Conventional ... -
Improved relay selection for decode-and-forward cooperative wireless networks under secrecy rate maximization
( Institute of Electrical and Electronics Engineers Inc. , 2014 , Conference)Privacy and security have an increasingly important role in wireless networks. A secure communication enables a legitimate destination to successfully retrieve information sent by a source, while it disables the eavesdropper ... -
Modeling and analysis of an infrastructure service request queue in multichannel V2I communications
( Institute of Electrical and Electronics Engineers Inc. , 2014 , Article)This paper presents a concise yet comprehensive description of a multichannel vehicle-to-infrastructure communication system. Existing mathematical models for such a system overlook some of its essential behavioral ... -
Cognitive relay-sharing by using hierarchical modulation under interference constraints
( Institute of Electrical and Electronics Engineers Inc. , 2014 , Conference)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 ... -
Outage performance of cooperative systems under IQ imbalance
( Institute of Electrical and Electronics Engineers Inc. , 2014 , Article)In this contribution, we investigate the outage performance of OFDM-based Decode and Forward (DF), Amplify and Forward (AF) and Controlled DF (CDF) cooperative systems under IQ Imbalance (IQI). In particular, tractable and ... -
Contribution of Shell Eco-Marathon engineering design experience to soft skills development: A qualitative analysis in the Asian context
( Institute of Electrical and Electronics Engineers Inc. , 2014 , Conference)Recent studies emphasize the needs of a wider set of skills engineers require than ever thought. Engineering curricula have been frequently criticized. Engineering design experience is one remedial way of heavy theory ... -
Asymptotic BER analysis of FSO with multiple receive apertures over M-distributed turbulence channels with pointing errors
( Optical Society of American (OSA) , 2014 , Article)In this paper, we consider a free-space optical (FSO) communication with multiple receive apertures over M-distributed turbulence channels with pointing errors. In particular, we consider two different combining schemes ... -
Inter-relay Interference management schemes for multi-user cooperative wireless networks
( Institute of Electrical and Electronics Engineers Inc. , 2014 , Conference)In this paper, two cooperative communications schemes with inter-relay interference (IRI) management are proposed for multi-user wireless networks. The first scheme (Interference management at relay station (IMR)) uses the ... -

(2013 , Conference)The paper provides a review of the curriculum and pedagogy of engineering economics course, which is normally taken by engineering students of different disciplines. Literature reviews of studies and courses syllabuses on ... -
Cooperative communications scheme with interference management under ICI for OFDM LTE-A systems
( IEEE Computer Society , 2013 , Conference)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 ... -
On hierarchical network coding versus opportunistic user selection for two-way relay channels with asymmetric data rates
( IEEE , 2013 , Article)We address in this paper the challenge of coping with asymmetric data rates in two-way relay channels. We consider a relay network comprising two sources and one relay. The sources communicate at different rates through ... -
Prior zero forcing for cognitive relaying
( IEEE , 2013 , Article)Relaying primary signals by cognitive base-stations (CBSs) can help the primary system and thus win CBSs a higher chance to transmit their own signals. For this purpose, conventional zero-forcing (CZF) beamforming is a ... -
Performance analysis of selective cooperation in amplify-and-forward relay networks over identical Nakagami-m channels
( Wiley Online Library , 2013 , Article)In cooperative communications, multiple relays between a source and a destination can increase the diversity gain. Because all the nodes must use orthogonal channels, multiple-relay cooperation becomes spectrally inefficient. ... -
