Intelligent diagnosis of structural cracks with optimized sensing networkMicrosystem Technologies - Tập 19 - Trang 1653-1660 - 2013
Shudong Liu, Chunling Du, Jingliang Zhang
This paper considers intelligent diagnosis of structural cracks emanating from rows of rivet holes in thin metallic plates using active sensing network. Lamb waves are generated using actuators and propagate across the plates and received by sensors. We extract an effective feature called energy ratio change from time domain signals using wavelet transform. Then we develop neural networks using th...... hiện toàn bộ
Viscous flow past a porous sphere within a nonconcentric fictitious spherical cellMicrosystem Technologies - Tập 25 - Trang 1051-1063 - 2018
E. I. Saad
The quasi steady axisymmetrical flow of an incompressible viscous fluid past an assemblage of porous sphere situated at an arbitrary position within a virtual spherical cell along the line connecting their centers is analyzed using a combined analytical–numerical technique. At the fluid–porous interface, the stress jump boundary condition for the tangential stresses along with continuity of normal...... hiện toàn bộ

SU8 resist plasma etching and its optimisationMicrosystem Technologies - Tập 10 - Trang 357-359 - 2004
G. Hong, A. S. Holmes, M. E. Heaton
The thick photoresist SU8, by virtue of its good mechanical durability, water impermeability and dielectric properties on polymerisation, is widely used as a resin for making high aspect ratio, functional MEMS device structures and packaging parts. However, the difficulty associated with removal, stripping or re-patterning of the polymerised SU8 remains a serious issue. This paper presents a novel...... hiện toàn bộ
Adaptive RBF-PIDSMC control method with estimated model parameters for a piezo-actuated stageMicrosystem Technologies - Tập 27 - Trang 69-77 - 2020
Qun Chen, Zong-Xiao Yang
The aim of this work is to find an adaptive control scheme to realize precise position tracking for a piezo-actuated stage, which is usually very difficult to control due to the essential nonlinearity and unknown uncertainty. Firstly, a proportional-integral-derivative (PID) sliding mode controller is designed based on the established model and the estimated parameters. Then, in order to reduce th...... hiện toàn bộ
Dusty flow with different water based nanoparticles along a paraboloid revolution: thermal analysisMicrosystem Technologies - Tập 26 - Trang 925-945 - 2019
M. Gnaneswara Reddy, Asiful H. Seikh, M. V. V. N. L. Sudharani, Mohammad Rahimi-Gorji, Nabeel Alharthi
The thermal analysis on hydromagnetic two-dimensional flow of dusty nano fluid along an upper horizontal surface of paraboloid revolution have been scrutinized. The governing flow are derived under the assumptions of Boussinesq’s boundary layer approximation theory. The effects of Cattaneo-Christov heat flux, variable thermal conductivity, joule heating and viscous dissipation are incorporated in ...... hiện toàn bộ
Design and optimization of asymmetrical TFET using meta-heuristic algorithmsMicrosystem Technologies - Tập 27 - Trang 3457-3464 - 2021
Sagarika Choudhury, Krishna Lal Baishnab, Brinda Bhowmick, Koushik Guha, Jacopo Iannacci
The complex process of semiconductor device design requires precise models and efficient optimizers. This article puts forward an Asymmetrical Hetero-Dielectric (AHD) Triple Material Gate (TMG) n-type Junctionless Tunnel Field Effect Transistor (JL-TFET). A higher gate control is achieved by using triple material in control gate and hetero-dielectric oxide, which results in high ON current and low...... hiện toàn bộ
