Take the red pill for H3 and see how deep the rabbit hole goes
Nguyen, M.; Timmerer, C.; Pham, S.; Silhavy, D.; Beğen, Ali Cengiz (ACM, 2022-03-17)With the introduction of HTTP/3 (H3) and QUIC at its core, there is an expectation of significant improvements in Web-based secure object delivery. As HTTP is a central protocol to the current adaptive streaming methods ... -
Taking inventory changes into account while negotiating in supply chain management
Yavuz, Celal; Süslü, Çağıl; Aydoğan, Reyhan (SciTePress, 2020)In a supply chain environment, supply chain entities need to make joint decisions on the transaction of goods under the issues quantity, delivery time and unit price in order to procure/sell goods at right quantities and ... -
Teaching robots to cooperate with humans in dynamic manipulation tasks based on multi-modal human-in-the-loop approach
Peternel, L.; Petric, T.; Öztop, Erhan; Babic, J. (Springer Science+Business Media, 2014-01)We propose an approach to efficiently teach robots how to perform dynamic anipulation tasks in cooperation with a human partner. The approach utilises human sensorimotor learning ability where the human tutor controls the ... -
