    Detection of Frost-Resistance Property of Large-Size Concrete Based on Impact-Echo Method

    Qi Feng1, Zhengyue Ren2, Dan Wang3,*

    Structural Durability & Health Monitoring, Vol.17, No.1, pp. 71-88, 2023, DOI:10.32604/sdhm.2023.024912

    Abstract The dynamic elasticity modulus (Ed) is the most commonly used indexes for nondestructive testing to represent the internal damage of hydraulic concrete. Samples with a specific size is required when the transverse resonance method was used to detect the Ed, resulting in a limitation for field tests. The impact-echo method can make up defects of traditional detection methods for frost-resistance testing, such as the evaluation via the loss of mass or strength. The feasibility of the impact-echo method to obtain the relative Ed is explored to detect the frost-resistance property of large-volume hydraulic concretes on site. Results… More >

    Vibration of a Two-Layer “Metal+PZT” Plate Contacting with Viscous Fluid

    Zeynep Ekicioglu Kuzeci1,*, Surkay D. Akbarov2,3

    CMC-Computers, Materials & Continua, Vol.74, No.2, pp. 4337-4362, 2023, DOI:10.32604/cmc.2023.033446

    Abstract The present work investigates the mechanically forced vibration of the hydro-elasto-piezoelectric system consisting of a two-layer plate “elastic+PZT”, a compressible viscous fluid, and a rigid wall. It is assumed that the PZT (piezoelectric) layer of the plate is in contact with the fluid and time-harmonic linear forces act on the free surface of the elastic-metallic layer. This study is valuable because it considers for the first time the mechanical vibration of the metal+piezoelectric bilayer plate in contact with a fluid. It is also the first time that the influence of the volumetric concentration of the… More >

    CNTFET Based Grounded Active Inductor for Broadband Applications

    Muhammad I. Masud1,2,*, Nasir Shaikh-Husin2, Iqbal A. Khan1, Abu K. Bin A’Ain2

    CMC-Computers, Materials & Continua, Vol.73, No.1, pp. 2135-2149, 2022, DOI:10.32604/cmc.2022.026831

    Abstract A new carbon nanotube field effect transistor (CNTFET) based grounded active inductor (GAI) circuit is presented in this work. The suggested GAI offers a tunable inductance with a very wide inductive bandwidth, high quality factor (QF) and low power dissipation. The tunability of the realized circuit is achieved through CNTFET based varactor. The proposed topology shows inductive behavior in the frequency range of 0.1–101 GHz and achieves to a maximum QF of 9125. The GAI operates at 0.7 V with 0.337 mW of power consumption. To demonstrate the performance of GAI, a broadband low noise amplifier (LNA) More >
