Abstract The article proposes a nonlinear optimal (H-infinity) control approach for type of underactuated power-line inspection robots. To implement this scheme, the state-space model robots undergoes first approximate linearization around temporary operating point, through first-order Taylor series expansion and computation associated Jacobian matrices. select feedback gains controller an alge...

Inspection is an effective but also expensive quality assurance activity to find defects early during software development. The defect detection process, team size, and staff hours invested can have a considerable impact on the defect detection effectiveness and cost-benefit of an inspection. In this paper, we use empirical data and a probabilistic model to estimate this impact for nominal (non...

In recent years, wavelet thresholding procedures have been widely applied to the field of nonparametric function estimation. They excel in the areas of spatial adaptivity, computational efficiency and asymptotic optimality. Among the various thresholding techniques studied in the literature, there are the term-byterm thresholding (hard, soft, . . . ) initially developed by Donoho and Johnstone ...

A model of sentence-picture integration developed by Carpenter and Just (1975) predicts that picturesentence integration ease/difficulty depends on picturesentence match/mismatch respectively. Recent findings by Underwood, Jebbet, and Roberts (2004), however, fail to find a match/mismatch difference for serial picture-sentence presentation in a sentence verification study. In a sentence compreh...
