Bayesian damage characterization based on probabilistic model of scattering coefficients and hybrid wave finite element model scheme
(2019)Ultrasonic Guided Wave(GW) has been proven to be sensitive to small damage. Motivated by the fact that the quantitative relationship between wave scattering and damage intensity can be described by scattering properties, ... -
Cough Sound Classification Based on Similarity Metrics
(2021)Cough and respiratory sound processing can assist in the early diagnosis of infections such as Covid-19. Even asymptomatic Covid-19 patients can be diagnosed early enough if appropriate speech modeling and signal-processing ... -
The effect of railway local irregularities on ground vibration
(2015)The environmental effects of ground-borne vibrations generated due to localised railway defects is a growing concern in urban areas. Frequency domain modelling approaches are well suited for predicting vibration levels on ... -
Feature extraction and pattern recognition from fisheye images in the spatial domain
(2018)Feature extraction for pattern recognition is a very common task in image analysis and computer vision. Most of the work has been reported for images / image sequences acquired by perspective cameras. This paper discusses ... -
Railway-induced ground vibrations in the presence of local track irregularities and wheel flats
(2015)Rapid growth in railway infrastructure has led to numerous environmental technical challenges. This includes ground-borne vibration, which is becoming an increasing problem, particularly in urban environments. A common ... -
Robust disturbance decoupling with simultaneous exact model matching via static measurement output feedback
(1999)The problem of robust exact model matching with simultaneous robust disturbance decoupling for linear systems with nonlinear uncertain structure (NLUS) and with measurable and non measurable disturbances is solved via an ... -
Stability analysis of the simplest Takagi-Sugeno fuzzy control system using circle criterion
(2007)In this paper, we present two sufficient conditions in the frequency domain for the global stability analysis of the simplest Takagi-Sugeno (T-S) fuzzy control system, based on the circle criterion and its graphical ...
