A fast circuit topology for finding the maximum of n k-bit numbers
Yuce, B.; Uğurdağ, Hasan Fatih; Gören, S.; Dundar, G. (IEEE, 2013)Finding the value and/or address (position) of the maximum element of a set of binary numbers is a fundamental arithmetic operation. Numerous systems, which are used in different application areas, require fast (low-latency) ... -
Fast one- and two-pick fixed-priority selection and muxing circuits
Tosun, Mustafa; Özkan, M. Akif; Güzel, Aydin Emre; Uğurdağ, Hasan Fatih (IEEE, 2016)Priority encoders and arbiters usually drive multiplexers (muxes). Latency optimization of priority encoders and multiplexer trees has usually been handled separately in the literature. However, in some applications with ... -
Fault masking as a service
Gülcü, Koray; Sözer, Hasan; Aktemur, Tankut Barış; Ercan, Ali Özer (Wiley, 2014-07)In SOA, composite services depend on a set of partner services to perform their tasks. These partner services may become unavailable because of system and/or network faults, leading to an increased error rate for the ... -
Fault masking as a service
Gülcü, Koray (2013-01)In service-oriented architectures, composite services depend on a set of partner services to perform their tasks. These partner services may become unavailable due to system and/or network faults, leading to an increased ... -
Feature extraction for enhancing data-driven urban building energy models
Bolluk, Muhammed Said; Seyis, Senem; Aydoğan, Reyhan (European Council on Computing in Construction (EC3), 2023)Building energy demand assessment plays a crucial role in designing energy-efficient building stocks. However, most studies adopting a data-driven approach feel the deficiency of datasets with building-specific information ... -
Feature-based rationale management system for supporting software architecture adaptation
Tekinerdoğan, B.; Sözer, Hasan; Akşit, M. (World Scientific Publishing Co., 2012-11)Each software architecture design is the result of a broad set of design decisions and their justifications, that is, the design rationale. Capturing the design rationale is important for a variety of reasons such as ... -
FedADC: Accelerated federated learning with drift control
Özfatura, E.; Özfatura, Ahmet Kerem; Gündüz, D. (IEEE, 2021)Federated learning (FL) has become de facto framework for collaborative learning among edge devices with privacy concern. The core of the FL strategy is the use of stochastic gradient descent (SGD) in a distributed manner. ... -
Femto hücre erişim noktaları için uygulama bazlı takvimleyicilerin önemi
Mungan, Devin; Ferazoğlu, Gülden; Sunay, Mehmet Oğuz (IEEE, 2012)In this paper, it is proposed that in order to guarantee a certain level of Quality of service (QoS) for different applications in a femtocell network, it is necessary to use application-based scheduling in femtocell access ... -
Field programmable gate arrays implementation of dual tree complex wavelet transform
Canbay, F.; Levent, Vecdi Emre; Serbes, G.; Goren, S.; Aydin, N. (IEEE, 2015)Due to the inherent time-varying characteristics of physiological systems, most biomedical signals (BSs) are expected to have non-stationary character. Therefore, any appropriate analysis method for dealing with BSs should ... -
The fifth automated negotiating agents competition (ANAC 2014)
Fujita, K.; Aydoğan, Reyhan; Baarslag, T.; Ito, T.; Jonker, C. (Springer Science+Business Media, 2016)In May 2014, we organized the Fifth International Automated Negotiating Agents Competition (ANAC 2014) in conjunction with AAMAS 2014. ANAC is an international competition that challenges researchers to develop a successful ... -
Finding event correlations in federated wireless sensor networks
Arı, İsmail; Çelebi, Ömer Faruk (IEEE, 2011)Event correlation engines help us find events of interest inside raw sensor data streams and help reduce the data volume, simultaneously. This paper discusses some of the challenges faced in finding event correlations over ... -
