Sparse channel estimation for OFDM-based underwater acoustic systems in rician fading with a new OMP-MAP algorithm
(IEEE, 2019-03-15)In this paper, a new channel estimation algorithm is proposed that exploits channel sparsity in the time domain for an orthogonal frequency division multiplexing (OFDM)-based underwater acoustical (UWA) communications ... -
Sparse channel estimation for OFDM-based underwater cooperative systems with amplify-and-forward relaying
(IEEE, 2014)This paper is concerned with a challenging problem of channel estimation for amplify-and-forward cooperative relay based orthogonal frequency division multiplexing (OFDM) systems in the presence of sparse underwater acoustic ... -
A sparse matrix‐vector multiplication method with low preprocessing cost
(Wiley, 2018-11-10)Sparse matrix-vector multiplication (SpMV) is a crucial operation used for solving many engineering and scientific problems. In general, there is no single SpMV method that gives high performance for all sparse matrices. ... -
Spatial configuration and passenger behavior at complex buildings İstanbul Sabiha Gökçen Airport
(Western Norway University of Applied Sciences (HVL), 2022)The behavior of the passengers in complex buildings may be affected by the spatial configuration of the building, also the functional demands of each individual. This research investigates complex buildings’spatial ... -
Spatial language use predicts spatial memory of children: evidence from sign, speech, and speech-plus-gesture
(The Cognitive Science Society, 2021)There is a strong relation between children’s exposure to spatial terms and their later memory accuracy. In the current study, we tested whether the production of spatial terms by children themselves predicts memory accuracy ... -
Spatial power spectrum of natural water turbulence with any average temperature, salinity concentration, and light wavelength
(The Optical Society, 2020-10-01)The power spectrum of water optical turbulence is shown to vary with its average temperature < T > and average salinity concentration < S >, as well as with light wavelength lambda. This study explores such variations for ... -
Spatial reason of the state: the role of space in protest repression in Turkey
(Taylor & Francis, 2023)Between 2007 and 2019 the Turkish regime used protest bans extensively in order to impede collective mobilization. In this paper, drawing on Michel Foucault’s discussion of raisond’état and an original dataset of protest ... -
Speaker adaptation with deep learning for text-to-speech synthesis systems
End-to-end (e2e) speech synthesis systems have become popular with the recent introduction of letter-to-spectrogram conversion systems, such as Tacotron, that use encoder-decoder-based neural architectures. Even though ... -
Speaker adaptation with minimal data in statistical speech synthesis systems
(2014-09)Statistical speech synthesis (SSS) systems have the ability to adapt to a target speaker with a couple of minutes of adaptation data. Developing adaptation algorithms to further reduce the number of adaptation utterances ... -
Speaking and gesturing guide event perception during message conceptualization: Evidence from eye movements
(Elsevier, 2022-08)Speakers' visual attention to events is guided by linguistic conceptualization of information in spoken language production and in language-specific ways. Does production of language-specific co-speech gestures further ... -
Speaking but not gesturing predicts event memory: a cross-linguistic comparison
(Cambridge University Press, 2022-09)Every day people see, describe, and remember motion events. However, the relation between multimodal encoding of motion events in speech and gesture, and memory is not yet fully understood. Moreover, whether language ... -
Speaking but not gesturing predicts motion event memory within and across languages
(The Cognitive Science Society, 2019)In everyday life, people see, describe and remember motion events. We tested whether the type of motion event information (path or manner) encoded in speech and gesture predicts which information is remembered and if this ... -

Spectral tuning of near-field radiative heat flux between two thin silicon carbide films
(Institute of Physics, 2010)Spectral distributions of radiative heat flux between two thin silicon carbide films separated by sub-wavelength distances in vacuum are analysed. An analytical expression for the near-field flux between two layers of ... -
Spectrally selective filter design for passive radiative cooling
(The Optical Society, 2020-04-01)Radiative cooling is potentially one of the most innovative approaches to reducing energy density in buildings and industry, as well as achieving higher levels of energy efficiency. Several studies have reported the design ...
