II. Methodology A. Modelling of faulty circuit with the aid of linear fractional transformation As the first step of stability analysis, the model of CUT with faults in its physical parameters must be designed on a unified linear fractional transformation (LFT) framework [12]. Suppose G(s) is a stable, real rational transfer function matrix of a linear time invariant CUT. The idea is to separat...

The importance of the equipment and secondary systems in seismic design and performance evaluation is well recognized and has been the subject of many studies. In all of these studies, earthquake is considered as a single component, and in most of them the primary system is considered as shear building. Most attention has been concentrated on the response of secondary system and its response sp...

In this study, we propose a function-on-function linear quantile regression model that allows for more than one functional predictor to establish flexible and robust approach. The proposed is first transformed into finitedimensional space via the principal component analysis paradigm in estimation phase. It then approximated using estimated functions, parameter of constructed based on scores. a...

[1] Reactive transport modeling is often used in support of bioremediation and chemical treatment planning and design. There remains a pressing need for practical and efficient models that do not require (or assume attainable) the high level of characterization needed by complex numerical models. We focus on a linear systems or transfer function approach to the problem of reactive tracer transp...

Maximization of the energy transfer ratio for timelimited signals over linear channels is considered. The case of linear channels with rational transfer function is addressed and a general procedure for the analytic solution of the maximization problem is outlined. The maximum energy transfer ratio over a fixed time interval is evaluated in some cases of interest. Two performance metrics—the en...

We recorded neural activity from ensembles of neurons in areas 5 and 2 of parietal cortex, while two monkeys copied triangles, squares, trapezoids, and inverted triangles and used both linear and nonlinear models to predict the hand velocity from the neural activity of the ensembles. The linear model generally outperformed the nonlinear model, suggesting a reasonably linear relation between the...

ABSTRACT: An approximate approach for the frequencyand time-domain aeroelastic analysis of bridge decks is presented. The aerodynamic transfer functions are approximated as a linear function with the coefficients determined through minimization of the weighted error between the exact and approximated transfer function. The weighting function in optimization is introduced for the improved approx...

Time-intensity measurements of ultrasonic-contrast microbubbles based on the dilution theory have been used to assist blood flow estimation. The compartment model has been employed to describe the dilution process. Under the linear and time-invariant assumption, the time-intensity curve measured at the output of a compartment (i.e., blood mixing chamber) is the convolution of the input time-int...
