Geopolymer is an environment-friendly cementitious material, which can effectively immobilize heavy metals. However, the existing study on solidification/stabilization (S/S) of heavy metal contaminated soil using geopolymer is very limited. In order to investigate the effects of geopolymer produced by activating fly ash (FA) and ground granulated blast-furnace slag (GGBS) (FA + GGBS) with composite activator of Na2SiO3 and NaOH on environmental and engineering properties of Pb2+ and Cd2+ contami...

Seismic response of the pile-supported structure is strongly affected by soil–pile interaction (SPI) because the depth, properties and density of the layered soil differ for every place. In this research, a general cyclic Beam on Nonlinear Winkler Foundation (BNWF) model was developed to account for the SPI problem's essential features, including lateral load characteristics, multilayer sandy soil density and stiffness hardening/degradation. A series of tests were conducted to develop the p-y cu...

Several studies have investigated palm trees’ microbiota infected with red palm weevil (RPW) (Rhynchophorus ferrugineus), the major pest of palm trees. This study compared the microbial communities of infected and uninfected palm trees in the Hail region, Northern Saudi Arabia, determined by high-throughput 16S rRNA gene sequencing by Illumina MiSeq. The results indicated that taxonomic diversity variation was higher for infected tree trunk than the healthy tree trunk. Soil samples from the vici...

The success of any company depends significantly on the realization of new products, which in turn depends on the selection of the best initial concept. Concept evaluations and selections during product development are critical decision-making steps and involve multiple-criteria decision-making (MCDM). This work proposes a concept evaluation and selection model which considers not only customer requirements (CR) but also the quality of the product features, defined in terms of feature quality le...

The study concerns the investigation of flexural behaviour of steel fibre reinforced concrete (SFRC) and conventional reinforce concrete (RC) beams incorporating steel fibre. Hooked-end steel fibres were used at the contents of 20 kg/m3, 40 kg/m3, 60 kg/m3, 80 kg/m3 and 100 kg/m3 in production of SFRC specimens and RC beams. Flexural tests were achieved on both SFRC and RC beams. Mechanical properties such as compressive strength, modulus of elasticity, flexural strength, toughness and toughness...

This paper presents the development of the outrigger structural system from the conventional outrigger to damped outrigger concepts. Outrigger structural system development from the conservative design as a rigid connection to a virtual connection with passive control, active control system, semi-active control system to hybrid control system is deliberated. Following brief overviews on history of outriggers, types of the outrigger, analysis of tall buildings without outriggers, formulation of e...

This paper exploits various meta-heuristic optimization techniques to learn PID controller parameters for nonlinear systems. The nonlinear systems considered here are well known ball and beam, inverted pendulum, and robotic arm manipulator. The gain parameters of the controllers are optimized by using two categories of meta-heuristic optimization techniques—swarm-based grasshopper optimization algorithm and particle swarm optimization and human-based, i.e., teacher learning-based optimization. M...

As one of the most challenging and promising topics in speech field, emotion speech synthesis is a hot topic in current research. At present, the emotion expression ability, synthesis speed and robustness of synthetic speech need to be improved. Cycle-consistent Adversarial Networks (CycleGAN) provides a two-way breakthrough in the transformation of emotional corpus information. But there is still a gap between the real target and the synthesis speech. In order to narrow this gap, we propose an ...

This paper develops a novel methodology to apply the piece-wise linear characteristic (PWLC) to coordinate the digital overcurrent relays (DOCRs) in meshed power systems regardless of their scales. In this approach, first, a table based on maximum short-circuit fault currents obtained using DIgSILENT software is produced in which the current seen by each relay is recorded by implementing a three-phase fault in front of other relays. Then, based on the fault currents achieved, the PWLC of each re...

Massive MIMO is an important framework of 5G and the Internet of Things (IoT). Signals radiated from a 5G antenna share the complex architecture. A system is therefore needed that can minimize complexity and provides good spectral efficiency and throughput. This is achieved by reducing RF chains which is an important constraint in an energy-efficient 5G system. In this paper, a new semi-orthogonal-based scheme is proposed to formulate SINR which maximizes throughput when RF chains are combined w...
