Sensitivity analysis of fracture scattering
We use a 2-D finite difference method to numerically calculate the seismic response of a single finite fracture in a homogeneous media. In our experiments, we use a point explosive source and ignore the free surface effect, so the fracture scattering wave field contains two parts: P-to-P scattering …

Sensitivity analysis of oscillating hybrid systems
… on the dynamic behavior of such systems is sensitivity analysis. A theory for sensitivity analysis with respect to the initial conditions and/or parameters of oscillating hybrid systems is developed and discussed. Boundary-value formulations are presented for initial conditions, period, …

Sensitivity analysis for nonsmooth dynamic systems
… can hinder conventional methods for simulation, sensitivity analysis, and optimization, and can be introduced, for example, by transitions in flow regime or thermodynamic phase, or through discrete changes in the operating mode of a process. While dedicated numerical methods exist for nonsmooth …

Sensitivity analysis of digital filter structures
A coefficient sensitivity measure for state space recursive, finite wordlength, digital filters is developed and its relationship to the filter output quantization noise power is derived. The sensitivity measure is simply the sum of the L₂ norm of all first order partials of the system function …

Sensitivity analysis of wing aeroelastic responses
… of the wing design process. Availability of the sensitivity derivatives of the various critical speeds with respect to shape parameters of the wing could be very useful to a designer in the initial design phase, when several design changes are made and the shape of the final configuration is not …

Gradient-Based Sensitivity Analysis with Kernels
Emulation of computer experiments via surrogate models can be difficult when the number of input parameters determining the simulation grows any greater than a few dozen. In this dissertation, we explore dimension reduction in the context of computer experiments. The active subspace method is a …

Sensitivity analysis of ship longitudinal strength
… and efficient computer program (ULTSTR) for a sensitivity analysis of ship longitudinal strength, where this program was originally developed for calculating the collapse moment. Since the program is efficient it can be used to obtain ultimate strength variability for various values of …

Sensitivity analysis of nuclear fuel cycle transitions
… tools, Cyclus and DYMOND, with Dakota, a sensitivity analysis toolkit. This work conducted one-at-a-time, synergistic, and global sensitivity analysis with Cyclus-Dakota and DYMOND-Dakota, to understand the interdependence of input parameters on the transition performance from the current …

Sensitivity Analysis and Optimization of Multibody Systems
… as valuable means for dynamic performance analysis of mechanical systems. The evolution of theoretical and computational aspects of the multibody dynamics discipline make it conducive these days for other types of applications, in addition to pure simulations. One very important such …

Sensitivity Analysis of RFML-based SEI Algorithms
Radio Frequency Machine Learning (RFML) techniques for the classification tasks of Specific Emitter Identification (SEI) and Automatic Modulation Classification (AMC) have seen rapid improvements in recent years. The applications of SEI, a technique used to associate a received signal to an …

Sensitivity analysis on steady bionanofluid boundary layer flow
… technique programmed in Maple18. Lastly, sensitivity analysis presented from Minitab18 is invoked to figure out the dependency of response on multivariate independent variables. The skin friction coefficient increases with suction showing positive sensitivity but decreases with slip …

Sensitivity Analysis of the UNO Activated Sludge Model
Different types of mathematical models have been proposed to predict the activated sludge process final effluent quality. La Motta (2004b) developed a mathematical model linking the operating parameters of an activated sludge system and the classical limiting flux sludge settling theory. This …

Interval Markov chains: performance measures and sensitivity analysis.
… investigate if it was possible to use interval analysis as an alternative to sensitivity analysis. We explored this in the context of the SIR model, where the true value of the parameters of the model may not be known. Hence, if one were to be careful when using point estimates, one would …

Security of Watermarking Schemes Against Sensitivity Analysis Attacks
… In order to build such framework, we model sensitivity analysis attacks as a general watermark estimation problem in which the adversary controls how informative the measurements will be about the watermark. We evaluate the fundamental performance limits for the attacker's watermark …

Design sensitivity analysis for nonlinear dynamic thermoelastic systems
… formulations are developed for the design sensitivity analysis of linear and nonlinear dynamic thermoelastic systems. The variation of a general design functional is expressed in explicit form with respect to variations of the design quantities, i.e. material properties, applied loads, …

Sensitivity analysis of low-density jets and flames
… region is at the inlet of the domain. The sensitivity of the global-mode eigenvalues to force feedback and to heat and drag from a hot-wire is found using a general structural sensitivity framework. Force feedback can occur from a sensor-actuator in the flow or as a mechanism that drives …
