Arı, İsmail; Muhtaroğlu, Nitel (Elsevier, 2013-06)This paper presents an end-to-end discussion on the technical issues related to the design and implementation of a new cloud computing service for finite element analysis (FEA). The focus is specifically on performance ... -
Design and implementation of a data stream management system with advanced complex event processing capabilities
Ölmezoğulları, Erdi (2013-06)The world has seen proliferation of data stream applications over the last years. These applications include computer network monitoring, Radio Frequency Identication (RFID)-based supply chain and traffic management systems, ... -
Design for ARINC 653 conformance: architecting independent validation of a safety-critical RTOS
Alptekin, A.; Yilmazer, Y.; Usug, U.; Koca, F.; İnçki, Koray (IEEE, 2014)The ARINC 653 specification not only provides a standard application programming interface for an RTOS, but also specifies how to validate an ARINC 653 based RTOS. ARINC 653 Part 3 Conformity Test Specification specifies ... -
Detection of Alzheimer's disease using prosodic cues in conversational speech
Khodabakhsh, Ali; Kuşçuoğlu, Serhan; Demiroğlu, Cenk (IEEE, 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 ... -
Detection of malicious social bots: A survey and a refined taxonomy
Latah, Majd (Elsevier, 2020-08-01)Social hots represent a new generation of hots that make use of online social networks (OSNs) as command and control (C&C) channels. Malicious social hots have been used as tools for launching large-scale spam campaigns, ... -
Deterministic neural illumination mapping for efficient auto-white balance correction
Kınlı, Osman Furkan; Yılmaz, Doğa; Özcan, Barış; Kıraç, Mustafa Furkan (IEEE, 2023)Auto-white balance (AWB) correction is a critical operation in image signal processors for accurate and consistent color correction across various illumination scenarios. This paper presents a novel and efficient AWB ... -
Developmental scaffolding with large language models
Çelik, B.; Ahmetoglu, A.; Ugur, E.; Öztop, Erhan (IEEE, 2023)Exploration and self-observation are key mechanisms of infant sensorimotor development. These processes are further guided by parental scaffolding to accelerate skill and knowledge acquisition. In developmental robotics, ... -
DiBLIoT: A distributed blacklisting protocol for iot device classification using the hashgraph consensus algorithm
Tarlan, Ozan; Şafak, I.; Çakmakçı, Kübra Kalkan (IEEE Computer Society, 2022)Industrial applications require highly reliable, secure, low-power and low-delay communications. However, wireless communication links in the industrial environment suffer from various channel impairments which can compromise ... -
DILAF: A framework for distributed analysis of large-scale system logs for anomaly detection
Astekin, M.; Zengin, H.; Sözer, Hasan (Wiley, 2019-02)System logs constitute a rich source of information for detection and prediction of anomalies. However, they can include a huge volume of data, which is usually unstructured or semistructured. We introduce DILAF, a framework ... -
Discovering frequent patterns to bootstrap trust
Şensoy, Murat; Yilmaz, B.; Norman, T. J. (Springer International Publishing, 2013)When a new agent enters to an open multiagent system, bootstrapping its trust becomes a challenge because of the lack of any direct or reputational evidence. To get around this problem, existing approaches assume the same ... -
Discovering predictive relational object symbols with symbolic attentive layers
Ahmetoglu, A.; Celik, B.; Öztop, Erhan; Uğur, E. (IEEE, 2024-02-01)In this letter, we propose and realize a new deep learning architecture for discovering symbolic representations for objects and their relations based on the self-supervised continuous interaction of a manipulator robot ... -
Disentangling human trafficking types and the identification of pathways to forced labor and sex: an explainable analytics approach
Eryarsoy, E.; Topuz, K.; Demiroğlu, Cenk (Springer, 2023-07)Terms such as human trafficking and modern-day slavery are ephemeral but reflect manifestations of oppression, servitude, and captivity that perpetually have threatened the basic right of all humans. Operations research ... -
A distributed approach for bitrate selection in HTTP adaptive streaming
Bentaleb, A.; Beğen, Ali Cengiz; Harous, S.; Zimmermann, R. (ACM, 2018)Past research has shown that concurrent HTTP adaptive streaming (HAS) players behave selfishly and the resulting competition for shared resources leads to underutilization or oversubscription of the network, presentation ... -
Distributed decision trees
Irsoy, O.; Alpaydın, Ahmet İbrahim Ethem (Springer, 2022)In a budding tree, every node is part internal node and part leaf. This allows representing the tree in a continuous parameter space and training it with backpropagation, like a neural network. Unlike a traditional tree ... -
