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 ...
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 ...
High temperature characteristics of Al2024/SiC metal matrix composite fabricated by friction stir processing
(Elsevier, 2018-07-25)
In the present study, friction stir processing (FSP) is used for the synthesis of an aluminum metal matrix composite (MMC) reinforced by SiC particles. MMC specimens with reinforced microstructures exhibited significant ...
Parenting styles and Turkish children’s emotion regulation: The mediating role of parent-teacher relationships
(Springer, 2021-09)
The current study examined the contributions of parenting styles (inductive reasoning and punishment) and parent-teacher relationships to Turkish preschool children’s emotion regulation, with a specific focus on the mediating ...
Digital design literacy in K-9 education: Experiences from pioneer teachers
(Association for Computing Machinery, Inc, 2021-06-24)
Based on a comprehensive account of digital design literacy, we report from an interview study with pioneer teachers to disclose their experiences from teaching design in formal K-9 education. Unique for the study is that ...
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 ...
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 ...
An integrated SWOT based fuzzy AHP and fuzzy MARCOS methodology for digital transformation strategy analysis in airline industry
(Elsevier, 2021-10)
Driven by business strategies, digital transformation (DT) facilitates dramatic change in air passenger behavior. This study aims to determine and analyze different DT strategies (DTSs) with the help of an integrated ...
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. ...
3D neuromorphic wireless power transfer and energy transmission based synaptic plasticity
(IEEE, 2019)
Energy consumption combined with scalability and 3D architecture is a fundamental constraint for brain-inspired computing. Neuromorphic architectures including memristive, spintronic, and floating gate metal-oxide-semiconductors ...
