Advanced Intelligent Systems, EarlyView.This work presents an inchworm‐like dual‐balloon‐assisted colonoscopic robot (IDCR) based on a rod‐driven two‐segment continuum section. The IDCR enables the active straightening of the sigmoid colon through an inchworm‐like locomotion strategy, thereby avoiding loop formation.

PRACTICAL ASPECTS IN SOME NOT CLASSICAL METHODS FOR THE NUMERICAL EVALUATION OF CPV- INTEGRALS
Ratio Mathematica, 1995 Two different not classical approaches are given for the numerical evaluation of weighted Cauchy principal value integrals, The first approach is an interpolatory Gaussian integration over the unit half disc.The second method is a quasi interpolatory ...

The Euler Maclaurin expansion for the Cauchy Principal Value integral
Numerische Mathematik, 1985 Let \(Q^{(m)}f\) be the m-copy of the quadrature rule approximation Qf or \(Q^{(1)}f\) to the finite integral If having integrand f and interval [a,b]. For most rules Q and integrand functions f, \(Q^{(m)}f\) converges to If as m becomes infinite. For some Q and f, asymptotic expansions in m exist for the error functional \(Q^{(m)}f\)-If. The classical

Evolutionary morphology of the haplorhine hamate
The Anatomical Record, EarlyView.Abstract Primates adopt a variety of hand postures during an impressive diversity of locomotor and manipulative behaviors. Morphological research has found that elements of the hand skeleton, such as the hamate, hold key information for inferring hand use and locomotor kinematics in extinct species.

Asian Journal of Control, EarlyView.ABSTRACT The synchronization accuracy between the wafer stage and reticle stage in lithography is critical to overlay and critical dimension uniformity. Existing iterative learning control (ILC) methods indirectly optimize synchronization via time‐domain errors, failing to balance low‐frequency tracking accuracy and high‐frequency noise suppression ...

The Trapezoidal Rule for Computing Cauchy Principal Value Integral on Circle [PDF]
Mathematical Problems in Engineering, 2015 The composite trapezoidal rule for the computation of Cauchy principal value integral with the singular kernelcot((x-s)/2)is discussed. Our study is based on the investigation of the pointwise superconvergence phenomenon; that is, when the singular point coincides with some a priori known point, the convergence rate of the trapezoidal rule is higher ...

Generalized Mangler-type principal value integrals with an application to fracture mechanics [PDF]
, 1990 A generalized interpretation of the classical Mangler-type principal value integrals is proposed. This new interpretation in general is not equivalent to the classical one.

Asymptotic properties of cross‐classified sampling designs
Canadian Journal of Statistics, EarlyView.Abstract We investigate the family of cross‐classified sampling designs across an arbitrary number of dimensions. We introduce a variance decomposition that enables the derivation of general asymptotic properties for these designs and the development of straightforward and asymptotically unbiased variance estimators.

, 1990 This paper presents a new general method for the direct evaluation of Cauchy principal value integrals in several dimensions, which is an issue of major concern in any boundary element method analysis in applied mechanics.

Power spectral density and the brain
Canadian Journal of Statistics, EarlyView.Abstract Time series from M/EEG (magneto/electroencephalography) and ECoG (electrocorticography) recordings are common sources of information about brain function. The power spectral density (PSD) preserves much of this information, up to second order. In the current decade, a burst of brain diagnostics using the slope of log(PSD) has appeared.
