Finite Element Modeling of Drilling AZ91 Magnesium Foam Reinforced with Hollow Alumina Microspheres
(2021-07)
Novel AZ91 magnesium syntactic foams are a potential choice for temporary biomedical implants. In many cases, holes of various sizes need to be machined on the biomedical implants using the drilling process to facilitate ...
Comparison of Whole-class Discussion and Task-based Activity: A Small-Scale Study
(2020-05)
This study examined the participation patterns and effectiveness of two different sets of materials applied with two different treatments: Treatment 1 consisted of a Task-based activity; Treatment 2 used a whole-class ...
Discourse Effects on the Acquisition of the English Causative Forms: Structured Input vs. Structured Output Practice.
(2020-05)
This research presents the results of a quasi-experimental empirical study investigating the effects of structured input activities and structured output tasks on the acquisition of English causative forms. The study is ...
In-Vitro Degradation of Hollow Silica Reinforced Magnesium Syntactic Foams in Different Simulated Body Fluids for Biomedical Applications
(MDPI, 2020)
This article reports the mechanical and biocorrosion behaviour of hollow silica nanosphere (SiO₂) reinforced (0.5–2 vol.%) magnesium (Mg) syntactic foams. Room temperature tensile properties’ characterization suggests that ...
Behavioral Modeling of GaN Doherty Power Amplifiers Using Memoryless Polar Domain Functions and Deep Neural Networks
(IEEE, 2020)
In this paper, novel Doherty Power Amplifier (DPA) models are presented. The motivation behind the proposed models is to accurately predict static nonlinearities in the compression regions of the carrier and peaking ...
A Comprehensive Method of Ion Exchange Resins Regeneration and Its Optimization for Water Treatment
(IntechOpen, 2020-08)
Ion exchange membranes, specifically resin technology, lie at the heart of electrolytically conductive systems used in the treatment of wastewater. This chapter deals with ion exchange deionization and the effect of resin ...
Critical Review of the Evolution of Project Delivery Methods in the Construction Industry
(MDPI, 2021)
Selecting the appropriate project delivery method (PDM) is a very significant managerial decision that impacts the success of construction projects. This paper provides a critical review of related literature on the evolution ...
Effect of Aggregate Type and Specimen Configuration on Concrete Compressive Strength
(MDPI, 2020)
In this paper, concrete mixes utilizing two sizes of natural aggregate and two sources of lightweight and recycled aggregates were used to investigate the effect of aggregate type and specimen size and shape on the compressive ...
A Subspace Identification Technique for Real Time Stability Assessment of Droop Based Microgrids
(IEEE, 2021-11)
Real time detection of the microgrid stability is crucial for determining and adjusting the power-sharing droop controllers' gains to maintain a sufficient stability margin. Maintaining minimum relative stability should ...
Suppressing the Capacitor Voltage Fluctuations in Low Frequency Operation of Modular Multilevel Converters
(IEEE, 2020)
Lowfrequency operation in the modular multilevel converters (MMCs) is enabled by applying a reference common mode voltage and circulating currents at a frequency much higher than the desired output frequency. The frequency ...
