Exploring the performance limits of MOF/polymer MMMs for O2/N2 separation using computational screening
(Elsevier, 2021-01-15)Air separation is one of the most challenging separations because of the very similar molecular dimensions of gas molecules. We used a high-throughput computational screening approach to identify the upper performance ... -
First-principle diffraction simulations as a tool to solve the nanodiffraction problem
(International Union of Crystallography, 2021-08)N/A -
A new LED response model and its application to pre-equalization in VLC systems
(IEEE, 2021-09-01)With the growing interest in visible light communication (VLC), it is desired to transmit data at very high rates despite the LED's bandwidth becoming a bottleneck. The bandwidth of a white LED usually ranges between ... -
Effect of metal–organic framework (MOF) database selection on the assessment of gas storage and separation potentials of MOFs
(Wiley, 2021-03-29)Development of computation-ready metal–organic framework databases (MOF DBs) has accelerated high-throughput computational screening (HTCS) of materials to identify the best candidates for gas storage and separation. These ... -
On the convergence of the nonlocal nonlinear model to the classical elasticity equation
(Elsevier, 2021-12)We consider a general class of convolution-type nonlocal wave equations modeling bidirectional propagation of nonlinear waves in a continuous medium. In the limit of vanishing nonlocality we study the behavior of solutions ... -
Automated defect prioritization based on defects resolved at various project periods
(Elsevier, 2021-09)Defect prioritization is mainly a manual and error-prone task in the current state-of-the-practice. We evaluated the effectiveness of an automated approach that employs supervised machine learning. We used two alternative ... -
Visible light communication for connected vehicles: How to achieve the omnidirectional coverage?
(IEEE, 2021)Visible light communication (VLC) is based on the idea of modulating the light intensity of LEDs to transmit information and enables the dual use of exterior automotive and road side infrastructure lighting for both ... -
Minimizing cogging torque in permanent magnet synchronous generators for small wind turbine applications
(Gazi University, 2021-06)Permanent magnet synchronous generators have a wide usage among electric machines, especially in small wind turbine systems. However permanent magnet synchronous generators suffer from cogging torque due to the magnetic ... -
Emotion as an emergent phenomenon of the neurocomputational energy regulation mechanism of a cognitive agent in a decision-making task
(Sage, 2021-02)Biological agents need to complete perception-action cycles to perform various cognitive and biological tasks such as maximizing their wellbeing and their chances of genetic continuation. However, the processes performed ... -
Would you imagine yourself negotiating with a robot, Jennifer? Why not?
(IEEE, 2022-02)With the improvement of intelligent systems and robotics, social robots are becoming part of our society. To accomplish complex tasks, robots and humans may need to collaborate, and when necessary, they need to negotiate ... -
Battery integrated off-grid DC fast charging: Optimised system design case for California
(IEEE, 2021)Global acceptance and exploitation of electric vehicles (EV) is no doubt a fact. There are two major factors beneath this growth; 1. increasing battery capacity thus rising range and 2. availability of DC fast charging ... -
Finite-SNR diversity gain analysis of FSO systems over gamma-gamma fading channels with pointing errors
(IEEE, 2021-06)Free space optical (FSO) communication systems are subject to turbulence-induced fading as a result of fluctuations in the refractive index. Gamma-Gamma (GG) distribution is commonly used in the literature to characterize ... -
FedADC: Accelerated federated learning with drift control
(IEEE, 2021)Federated learning (FL) has become de facto framework for collaborative learning among edge devices with privacy concern. The core of the FL strategy is the use of stochastic gradient descent (SGD) in a distributed manner. ... -
Flexible generalized spatial modulation for visible light communications
(IEEE, 2021-01)Adaptive spatial modulation (ASM) varies the modulation size across the transmit light-emitting diodes (LEDs) to improve the overall spectral efficiency of visible light communication (VLC) systems. This article proposes ... -
Predicting pore volume, compressive strength, pore connectivity, and formation factor in cementitious pastes containing fly ash
(Elsevier, 2021-09)This paper describes the use of thermodynamic modeling to predict the reaction products and properties of cementitious pastes containing fly ash. A pore partitioning model is used to estimate the gel and capillary pore ... -
Severe plastic deformation as a processing tool for strengthening of additive manufactured alloys
(Elsevier, 2021-08)For the first time, the novel combination of multi-pass equal channel angular extrusion/pressing (ECAE/P) and selective laser melting (SLM) was investigated. Herein, four passes of ECAP via route Bc at 150 °C were applied ... -
