Gabor filter based localization of needles in ultrasound guided robotic interventions
(IEEE, 2014)This paper presents an entropy based parameter tuning method for needle segmentation, and a probability map based needle tip estimation method using Gabor-based line filter. The proposed automatic parameter tuning method ... -
Gabor filter-based localization of straight and curved needles in 2D ultrasound images
(TÜBİTAK, 2020)2D ultrasound (US) is one of the most commonly used medical imaging devices for needle localization in biopsies. However, the produced images are low-resolution and contain an excessive number of artifacts, which makes the ... -
Game of protocols: Is QUIC ready for prime time streaming?
(Wiley, 2020-05)Quick User Datagram Protocol (UDP) Internet Connections (QUIC) is an experimental and low-latency transport protocol proposed by Google, which is still being improved and specified in the Internet Engineering Task Force ... -
Game of streaming players: Is consensus viable or an illusion?
(Association for Computing Machinery, Inc, 2019-08)The dramatic growth of HTTP adaptive streaming (HAS) traffic represents a practical challenge for service providers in satisfying the demand from their customers. Achieving this in a network where multiple players share ... -
A game theoretical approach for improving the operational efficiencies of less-than-truckload carriers through load exchanges
(Springer, 2021-09)Less-than-truckload (LTL) transportation offers fast, flexible and relatively low-cost transportation services to shippers. In order to cope with the effects of economic recessions, the LTL industry implemented ideas such ... -
Game theory based bitrate adaptation for Dash.Js reference player
(IEEE, 2018-11-28)Most existing DASH adaptive bitrate (ABR) schemes are designed to behave in their own self-interest and do not perform consistently in all network environments. In this work, we provide a practical implementation, materials ... -
Gamma-gamma türbülans kanallarında tüm-optik rölelemeli FSO sistemleri için röle seçimi
(IEEE, 2014)Bu bildiride, tüm-optiksel çoklu-röle kablosuz optik haberleşme sistemleri için Gamma-Gamma atmosferik türbülans kanalı varsayımı altında servis dışı kalma başarımı incelenmiştir. Röleler arası katı senkronizasyon ihtiyacından ... -
Gauss karışım modeli tabanlı konuşmacı belirleme sistemlerinde klasik MAP uyarlanması yönteminin performans analizi
(IEEE, 2010)Gaussian mixture models (GMM) is one of the most commonly used methods in text-independent speaker identification systems. In this paper, performance of the GMM approach has been measured with different parameters and ... -
Gauss karışım modeli tabanlı konuşmacı doğrulama sistemlerinde kişiye ve kanala uyarlanmada klasik MAP tabanlı yöntemlerin performans analizi
(IEEE, 2011)In this paper, performance of Gaussian mixture models (GMM) based algorithms implemented in Speech Processing Laboratory at Ozyegin University, within NIST SRE2004 and 2006 database was reported. Gaussian mixture models ... -
Geçmişe dönük hata tespit oranlarının zamanla değişen etkisine göre regresyon testlerinin önceliklendirilmesi
(CEUR-WS, 2014)Büyük ölçekli yazılım sistemlerinin regresyon testleri masraflıdır. Kaynak kısıtları sebebiyle genellikle tüm test durumlarını değerlendirmek mümkün olmamaktadır. Dolayısıyla, hataları mümkün olan en kısa sürede tespit ... -
The generalized fractional Benjamin–Bona–Mahony equation: Analytical and numerical results
(Elsevier, 2020-08)The generalized fractional Benjamin-Bona-Mahony (gfBBM) equation models the propagation of small amplitude long unidirectional waves in a nonlocally and nonlinearly elastic medium. The equation involves two fractional terms ... -
Generalized LED index modulation optical OFDM for MIMO visible light communications systems
(IEEE, 2016)In this paper, we propose a generalized light emitting diode (LED) index modulation scheme for multiple input multiple output-orthogonal frequency division multiplexing (MIMO-OFDM) visible light communications (VLC) systems. ... -
Generalized maximum-likelihood sequence detection for photon-counting free space optical systems
(IEEE, 2010-12)We investigate detection methods for on-off keying (OOK) photon-counting Free Space Optical (FSO) systems in the presence of turbulence-induced fading, assuming no channel state information at the receiver. To recover the ... -
Generalized performance analysis of mixed RF/FSO cooperative systems
(IEEE, 2016-01)Free space optical (FSO) links provide an efficient point-to-point wireless transmission solution. They are particularly useful for filling the connectivity gap between the radio frequency (RF) access network and the fiber ... -
Generalized performance analysis of mixed RF/FSO systems
(IEEE, 2014)We investigate the performance of dual-hop fixed-gain amplify-and-forward relaying systems over Nakagami-m and double generalized Gamma fading channels with pointing error for mixed radio frequency/free space optical ... -
A generalized stereotype learning approach and its instantiation in trust modeling
(Elsevier, 2018-08)Owing to the lack of historical data regarding an entity in online communities, a user may rely on stereotyping to estimate its behavior based on historical data about others. However, these stereotypes cannot accurately ... -
Generating fast logic circuits for m-select n-port round Robin arbitration
(IEEE, 2013)This paper generalizes the problem of Round Robin Arbitration (RRA) from 1-select to m-select (mRRA) and offers new circuit architectures for it. RRAs are found in networking equipment and computer systems with high ... -
Generating runtime verification specifications based on static code analysis alerts
(ACM, 2017)Runtime verification techniques verify dynamic system behavior with respect to a set of specifications. These specifications are often created manually based on system requirements and constraints. In this paper, we introduce ... -
Genetic algorithms and heuristics hybridized for software architecture recovery
(Springer, 2023-06-26)Large scale software systems must be decomposed into modular units to reduce maintenance efforts. Software Architecture Recovery (SAR) approaches have been introduced to analyze dependencies among software modules and ... -
Geometric design of micro scale volumetric receiver using system-level inputs: An application of surrogate-based approach
(Elsevier, 2023-09-15)Concentrating solar thermal power is an emerging renewable technology with accessible storage options to generate electricity when required. Central receiver systems or solar towers have the highest commercial potential ...
