A distributed approach for bitrate selection in HTTP adaptive streaming
(ACM, 2018)Past research has shown that concurrent HTTP adaptive streaming (HAS) players behave selfishly and the resulting competition for shared resources leads to underutilization or oversubscription of the network, presentation ... -
A distributed blacklisting protocol for iot device classification using the hashgraph consensus algorithm
Industrial applications require highly reliable, secure, low-power and low-delay communications. However, wireless communication links in the industrial environment suffer from various channel impairments which can compromise ... -
Distributed decision trees
(Springer, 2022)In a budding tree, every node is part internal node and part leaf. This allows representing the tree in a continuous parameter space and training it with backpropagation, like a neural network. Unlike a traditional tree ... -
Distributed MIMO for Li-Fi: Channel measurements, ray tracing and throughput analysis
(IEEE, 2021-08-15)LiFi has been considered as a promising candidate for future wireless indoor networks. The IEEE P802.15.13 and P802.11bb standardization groups agreed upon channel models generated using the non-sequential ray tracing ... -
A distributed virtual learning environment (DVLE) for a constructively aligned architectural design studio
(Festival Architettura Edizioni, Parma, Italy, 2021)In the last 30 years there has been extensive research about online teaching, outlining the importance of the interaction modes and the constructive alignment of the intended learning outcomes (ILO) and the teaching and ... -
Distributions of topological observables in inclusive three- and four-jet events in pp collisions at s√=7s=7TeV
(Springer, 2015-07)This paper presents distributions of topological observables in inclusive three- and four-jet events produced in pp collisions at a centre-of-mass energy of 7 TeVTeV with a data sample collected by the CMS experiment ... -
Diversity gain analysis of underwater vertical MIMO VLC links in the presence of turbulence
(IEEE, 2019)To satisfy the demands of high data rate underwater applications such as image and real-time video transmission, underwater visible light communication (UVLC) has emerged as an alternative to acoustic signaling. One of the ... -
Diversity techniques for ultraviolet communications
(2016-08)Strong molecular and aerosol scattering in ultraviolet (UV) wavelengths enable mechanisms where transmitter can communicate with the receiver in the absence of line of sight (LOS) link. Recent advances in solid state ... -
Diversity-multiplexing trade-off in coherent free-space optical systems with multiple receivers
(IEEE, 2010-12)In this paper, from an information theory point of view, we investigate the performance of a coherent freespace optical (FSO) communication system with multiple receive apertures over atmospheric turbulence channels. Our ... -
Diversity-multiplexing tradeoff for log-normal fading channels
(IEEE, 2016-07)Although there has been a growing interest on the study of diversity-multiplexing tradeoff (DMT), the existing works are mostly restricted to the outcomes reported for Rayleigh, Rician, and Nakagami fading channels. In ... -
Diversity-multiplexing tradeoff for network coded cooperative OFDMA systems
(2016-08)Cooperative communication (CC) exploits the broadcasting nature of wireless transmission and creates a distributed multiple-input multiple-output (MIMO) system among the wireless nodes which are physically separated from ... -
Diversity-multiplexing tradeoff for network coded cooperative OFDMA systems
(IEEE, 2015)Network coded cooperation (NCC) is an effective method to improve the throughput efficiency in cooperative wireless networks. In an effort to have further gains over the initial works, which build upon the assumption of ... -
Divorced yet still together: ongoing personal relationship and coparenting among divorced parents
(Taylor and Francis Group, 2017)This study examined the ongoing personal and emotional involvement between former spouses and its association with perceptions of the quality of the coparenting relationship. Dyadic analysis of 54 formerly married couples ... -
DMT analysis and optimal scheduling for two-hop parallel relay networks
(Elsevier, 2021-06)Two-hop parallel networks with half-duplex relays over quasi-static Rayleigh fading channels are considered. Assuming relays have only local channel state information, optimal communication schemes for these networks in ... -
DMT analysis of coherent free-space optical systems over atmospheric turbulence channels
(IEEE, 2010)In this paper, we investigate the diversity-multiplexing tradeoff (DMT) performance of a coherent free-space optical (FSO) communication system with multiple receive apertures over atmospheric turbulence channels. Our study ... -
DMT analysis of multi-hop coherent FSO communication over atmospheric channels
(IEEE, 2011)In this paper, we investigate the diversity-multiplexing tradeoff (DMT) of a multi-hop coherent free-space optical (FSO) system over atmospheric channels. We consider a relay-assisted FSO system with decode-and-forward ... -
DNN-based speaker-adaptive postfiltering with limited adaptation data for statistical speech synthesis systems
(IEEE, 2019)Deep neural networks (DNNs) have been successfully deployed for acoustic modelling in statistical parametric speech synthesis (SPSS) systems. Moreover, DNN-based postfilters (PF) have also been shown to outperform conventional ... -
Do display ads influence search? Attribution and dynamics in online advertising
(Elsevier, 2016-09)As firms increasingly rely on online media to acquire consumers, marketing managers rely on online metrics such as click-through rate (CTR) and cost per acquisition (CPA). However, these standard online advertising metrics ... -
Do entrepreneurs really create entrepreneurial cultures? When intentions do not match actions
(Boğaziçi Üniversitesi İktisadi ve İdari Bilimler Fakültesi, 2016)From the perspective that organizational cultures are shaped by their founders, it is expected that entrepreneurs create entrepreneurial cultures in line with their innovative approach. This paper challenges this expectation ... -
Do hedge funds’ exposures to risk factors predict their future returns?
(Elsevier, 2011-07)This paper investigates hedge funds’ exposures to various financial and macroeconomic risk factors through alternative measures of factor betas and examines their performance in predicting the crosssectional variation in ...
