Analysis of energy harvesting for green cognitive radio networks
Ercan, Ali Özer; Sunay, Mehmet Oğuz; Pollin, S. (IEEE, 2014)This paper develops a Markov Chain analysis framework for an RF energy harvesting cognitive radio network where the secondary system users are furnished with finite-sized batteries. We consider a network where the only ... -
Analysis of speaker similarity in the statistical speech synthesis systems using a hybrid approach
Güner, Ekrem; Mohammadi, A.; Demiroğlu, Cenk (IEEE, 2012)Statistical speech synthesis (SSS) approach has become one of the most popular and successful methods in the speech synthesis field. Smooth speech transitions, without the spurious errors that are observed in unit selection ... -
Analysis of speech-based measures for detecting and monitoring Alzheimer’s disease
Khodabakhsh, Ali; Demiroğlu, Cenk (Springer Science+Business Media, 2014)Automatic diagnosis of the Alzheimer’s disease as well as monitoring of the diagnosed patients can make significant economic impact on societies. We investigated an automatic diagnosis approach through the use of speech ... -
Anti-spoofing for text-independent speaker verification: An initial database, comparison of countermeasures, and human performance
Wu, Z.; Leon, P. L. de; Demiroğlu, Cenk; Khodabakhsh, Ali (IEEE, 2016-04)In this paper, we present a systematic study of the vulnerability of automatic speaker verification to a diverse range of spoofing attacks. We start with a thorough analysis of the spoofing effects of five speech synthesis ... -
An approach for detecting inconsistencies between behavioral models of the software architecture and the code
Çıracı, S.; Sözer, Hasan; Tekinerdogan, B. (IEEE, 2012)In practice, inconsistencies between architectural documentation and the code might arise due to improper implementation of the architecture or the separate, uncontrolled evolution of the code. Several approaches have been ... -
Arabic offensive language on twitter: Analysis and experiments
Mubarak, H.; Rashed, Ammar; Darwish, K.; Samih, Y.; Abdelali, A. (Association for Computational Linguistics (ACL), 2021)Detecting offensive language on Twitter has many applications ranging from detecting/predicting bullying to measuring polarization. In this paper, we focus on building a large Arabic offensive tweet dataset. We introduce ... -
An architecture viewpoint for modeling dynamically configurable software systems
Tekinerdogan, B.; Sözer, Hasan (Elsevier, 2017-01-01)Current software systems are rarely static and need to be able to change their topology and behavior to the changing context. To support the communication among stakeholders, guide the design decisions, and analyze the ... -
