Addressing the strength-ductility trade-off in a thermomechanical-processed high entropy alloy
(Elsevier, 2023-12-15)High entropy alloys (HEAs) have garnered significant attention due to their exceptional mechanical behavior. However, the influence of secondary phases and dislocation substructures has yet to be thoroughly investigated. ... -
Designing redundant cable-driven parallel robots for additive manufacturing using end-effector compliance index
(IEEE, 2023)This paper presents a methodology for optimizing cable anchor points for cable-driven parallel robots (CDPRs) for specific additive manufacturing tasks. Much of a CDPR's workspace is generally not used for printing tasks. ... -
FSO-based backhauling for airborne THz base stations
(IEEE, 2023)Airborne nodes in the form of high-altitude platform stations (HAPSs) or unmanned aerial vehicles (UAVs) can be used for backhauling and wireless access. In this paper, we investigate the cascaded free space optical ... -
ORTPiece: An ORT-based Turkish image captioning network based on transformers and WordPiece
(IEEE, 2023)Recent transformers-based systems are advancing image captioning applications. However, those works have been mainly applied to English-based image captioning problems. In this paper, we introduce a transformers-based ... -
Performance analysis of meta-learning based bayesian deep kernel transfer methods for regression tasks
(IEEE, 2023)Meta-learning aims to apply existing models on new tasks where the goal is 'learning to learn' so that learning from a limited amount of labeled data or learning in a short amount of time is possible. Deep Kernel Transfer ... -
Preview control-based jumping and spot-jogging trajectory generation for quadruped robots
(IEEE, 2023)This work presents a vertical center of mass (CoM) trajectory generation approach based on preview control for quadruped robots to accomplish agile locomotion tasks such as jumping and jogging. Conventionally, preview ... -
Characterization of orbital angular momentum-multiplexed FSO channel in the presence of pointing errors
(IEEE, 2023)Free space optical communication (FSO) uses laser transmitters at near-infrared wavelengths for line-of-sight wireless communication. Through the use of advanced laser beams instead of the conventional Gaussian-shaped beam, ... -

(Wiley, 2023-04)Physics-based earthquake ground motion simulations (GMS) have acquired significant growth over the last two decades, mainly due to the explosive developments of high-performance computing techniques and resources. These ... -
Model-predictive control of multilevel inverters: challenges, recent advances, and trends
(IEEE, 2023-09)Model-predictive control (MPC) has emerged as a promising control method in power electronics, particularly for multiobjective control problems such as multilevel inverter (MLI) applications. Over the past two decades, ... -
Land subsidence susceptibility mapping using interferometric synthetic aperture radar (InSAR) and machine learning models in a semiarid region of iran
(MDPI, 2023-04)Most published studies identify groundwater extraction as the leading cause of land subsidence (LS). However, the causes of LS are not only attributable to groundwater extraction. Other land-use practices can also affect ... -
Joint lifetime-outage optimization in relay-enabled IoT networks—A deep reinforcement learning approach
(IEEE, 2023-01)Network lifetime maximization in Internet of things (IoT) is of paramount importance to ensure uninterrupted data transmission and reduce the frequency of battery replacement. This letter deals with the joint lifetime-outage ... -
A machine learning approach to deal with ambiguity in the humanitarian decision-making
(Wiley, 2023-09)One of the major challenges for humanitarian organizations in response planning is dealing with the inherent ambiguity and uncertainty in disaster situations. The available information that comes from different sources in ... -
Explanation-based negotiation protocol for nutrition virtual coaching
(ACM, 2023)People’s awareness about the importance of healthy lifestyles is rising. This opens new possibilities for personalized intelligent health and coaching applications. In particular, there is a need for more than simple ... -
Gradient-based optimization of micro-scale pressurized volumetric receiver geometry and flow rate
(Elsevier, 2023-02)This study focuses on the design optimization of a micro-scale pressurized volumetric receiver by changing geometry and flow rate constrained by the volume, outlet air temperature, and outer surface temperature. The ... -
Out-of-band analysis of GFDM systems based on different self-interference types
(IEEE, 2023)This paper studies the impact of out-of-band (OOB) emission and interferences on the generalized frequency division multiplexing (GFDM) systems. Specifically, we analyze the effects of two types of independent self-interference, ... -
Equivalence for generalized Boolean functions
(American Institute of Mathematical Sciences, 2023-03)Equivalence plays a key-role for the classification of functions between elementary abelian groups V(p) n and V(p) k . One distinguishes between affine equivalence, extended affine (EA) equivalence, and the most general ...
