Evaluation of linguistic and prosodic features for detection of Alzheimer’s disease in Turkish conversational speech
Khodabakhsh, Ali; Yesil, Fatih; Guner, Ekrem; Demiroğlu, Cenk (Springer Science+Business Media, 2015-12)Automatic diagnosis and monitoring of Alzheimer’s disease can have a significant impact on society as well as the well-being of patients. The part of the brain cortex that processes language abilities is one of the earliest ... -
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 ... -
FPGA implementation of a dense optical flow algorithm using altera openCL SDK
Ulutaş, Umut; Tosun, Mustafa; Levent, Vecdi Emre; Büyükaydın, D.; Akgün, T.; Uğurdağ, Hasan Fatih (Springer International Publishing, 2017)FPGA acceleration of compute-intensive algorithms is usually not regarded feasible because of the long Verilog or VHDL RTL design efforts they require. Data-parallel algorithms have an alternative platform for acceleration, ... -
Introduction of a spatio-temporal mapping based POE method for outdoor spaces: Suburban university campus as a case study
Göçer, Özgür; Göçer, K.; Başol, Altuğ Melik; Kıraç, Mustafa Furkan; Özbil, A.; Bakovic, M.; Siddiqui, Faizan Pervez; Özcan, Barış (Elsevier, 2018-11)Outdoor spaces are important to sustainable cities because they establish a common identity for social life by improving quality of urban living. The relation between outdoor spaces and building groups, competency, use ... -
Spoofing attacks to i-vector based voice verification systems using statistical speech synthesis with additive noise and countermeasure
Özbay, Mustafa Caner; Khodabakhsh, Ali; Mohammadi, Amir; Demiroğlu, Cenk (IEEE, 2016)Even though improvements in the speaker verification (SV) technology with i-vectors increased their real-life deployment, their vulnerability to spoofing attacks is a major concern. Here, we investigated the effectiveness ... -
Synthesis of clock trees for sampled-data analog IC blocks
Yüce, B.; Korkmaz, S.; Esen, V. B.; Temizkan, Fatih; Tunç, Cihan; Güner, Gökhan; Başkaya, I. F.; Agi, İ.; Dündar, G.; Uğurdağ, Hasan Fatih (IEEE, 2013)This paper describes a methodology for automated design of clock trees in Sampled-Data Analog Circuits (SDACs). The current practice in the industry and academia for clock tree design of SDACs is a manual process, which ...
