Transdisciplinarity as a learning challenge: Student experiences and outcomes in an innovative course on wearable and collaborative robotics
Contribution: This study provides evidence for the benefit of short online courses for transdisciplinary competence development of graduate students. It shows the significant challenges students face while learning, and ... -
Sensorless position control of solenoid actuators for soft landing using super-twisting sliding mode control
(SAGE, 2022-07-24)This article presents an open-loop control methodology to achieve lower seating velocities (i.e. soft-landing) for solenoid-based injector systems which are widely used in automotive as fuel injection valves or gas exchange ... -
Design and analysis of a truncated elliptical-shaped chipless RFID tag
(TÜBİTAK, 2021)This article presents a novel polarization-insensitive chipless radio frequency identification tag having an encoding capacity of 11 bits. The proposed resonator design comprises discontinuous arc slots forming truncated ... -
Comprehensive study on UAV-based FSO links for high-speed train backhauling
(The Optical Society, 2021-09-20)In this paper, we introduce the idea of using unmanned aerial vehicle (UAV)-based free-space optical communication systems to backhaul high-speed trains. We introduce a composite channel model that includes effects of both ... -
Development of an aerial interface for extraction of the electrodynamic fingerprints of the single-photon detectors
(Wiley, 2021-12)In this study, a novel structure of semi array of antipodal Vivaldi antenna is designed to extract the RF radiations from the single-photon detectors in a quantum key distribution system. The proposed antenna covers a ... -
Road to salvation: Streaming clients and content delivery networks working together
(IEEE, 2021-11-01)Streaming media has truly become one of the most popular applications on the Internet. Viewers are spoiled for choice, and content providers compete to provide the best viewer experience. Traditionally, it has been challenging ... -
Hierarchical mixtures of generators for adversarial learning
Generative adversarial networks (GANs) are deep neural networks that allow us to sample from an arbitrary probability distribution without explicitly estimating the distribution. There is a generator that takes a latent ... -
Benchmarking torque control strategies for a torsion-based series elastic actuator
(IEEE, 2022-06)The diversity in torque-controlled actuators has enabled researchers to address numerous physical human-robot interaction applications with enhanced safety, dependability, and interaction capability [1]. Yet, only a few ... -
Temperature-dependent particle stability behavior and its effect on radiative transfer in water/SiO2 nanofluids
(Yildiz Technical University, 2021-09)Radiative transfer is one of the methods of energy transport that includes in a wide range of applications and we feel it in our daily lives. Thermal radiation transfer plays an effective role in the utilization of renewable ... -
Effect of photon statistics on vacuum fluctuations based QRNG
(IOP Publishing, 2021-06)The speed of quantum random number generators (QRNGs) is a major concern for practical applications. In this work, we introduce scattering as a method to enhance the randomness characteristics of the entropy source. This ... -
Low-cycle fatigue behavior of friction stir-welded copper joints
(Springer, 2021-11)Investigation of the fatigue response of friction stir-welded (FSWed) joints is especially important in the design and manufacturing of components with exposure to cyclic loading. In this study, cyclic response of FSWed ... -
Hospital service levels during drug shortages: Stocking and transshipment policies for pharmaceutical inventory
(Springer, 2022-07)In this study, we consider a health network that faces uncertain supply disruptions in the form of regional, nationwide, or worldwide drug shortages. Each hospital observes stochastic demand and if the drug is unavailable, ... -
Data model extension impact analysis
(IEEE, 2021)Relational database schemas are subject to change. For instance, columns of a table can be modified, deleted or extended. These changes have an impact on the source code that utilizes the corresponding table. They also ... -
Optical and radiative properties of individual and hybrid nanosuspensions: The effects of similar and dissimilar particle agglomerates on thermal radiation
(Yildiz Technical University, 2021-02)Nanosuspensions are proposed for use in improving the thermal efficiency of different thermal systems; including solar thermal power plants. Because of their excellent and unique thermo-optical properties, which are the ... -
Dynamic filtering and prioritization of static code analysis alerts
(IEEE, 2021)We propose an approach for filtering and prioritizing static code analysis alerts while these alerts are being reviewed by the developer. We construct a Prolog knowledge base that captures the data flow information in the ... -
Time-correlated sparsification for communication-efficient federated learning
(IEEE, 2021)Federated learning (FL) enables multiple clients to collaboratively train a shared model, with the help of a parameter server (PS), without disclosing their local datasets. However, due to the increasing size of the trained ... -
Content-aware playback speed control for low-latency live streaming of sports
(The ACM Digital Library, 2021)There are two main factors that determine the viewer experience during the live streaming of sports content: latency and stalls. Latency should be low and stalls should not occur. Yet, these two factors work against each ... -
COSMOS on steroids: a Cheap detector for cheapfakes
(The ACM Digital Library, 2021)The growing prevalence of visual disinformation has become an important problem to solve nowadays. Cheapfake is a new term used for the altered media generated by non-AI techniques. In their recent COSMOS work, the authors ... -
A cross-layer design for dynamic resource management of VLC networks
(IEEE, 2021-03)In this article, we propose a cross-layer resource management mechanism for an indoor multiuser visible light communication (VLC) access network. The physical layer builds upon DC-biased orthogonal frequency division ...
