Formalization of occupant feedback and integration with BIM in office buildings
(ASCE, 2021-01-01)
Occupant feedback is not effectively used in the facility management (FM) phase for operations and maintenance activities as well as retrofit and refurbishment investment decisions. One of the reasons is related to incomplete ...
Magnitude and wrap-phase OFDM for MIMO visible light communication systems
(IEEE, 2021-07)
Generalized light emitting diode (LED) index modulation (GLIM) has been proposed as an effective multiple-input multiple-output (MIMO) orthogonal frequency division multiplexing (OFDM) scheme for visible light communications ...
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 ...
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 ...
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. ...
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 ...
Mapping the scientific research of the life cycle assessment in the construction industry: A scientometric analysis
(Elsevier, 2021-10-15)
The interest toward the life cycle assessment studies in the construction industry has been increasing in the last decades. However, there is no existing study that focuses on mapping the scientific research of the LCAs ...
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 ...
