Self-reconfiguration of robotic manipulators under joint failure can be achieved via fault-tolerance strategies. Faulttolerant manipulators are required to continue their endeffector motion with a minimum velocity jump, when failures occur to their joints. Optimal fault tolerance of the manipulators requires a framework that can map the velocity jump of the end-effector to the compensating join...

Introduction: Measurement of proton transverse relaxation time (T2) can be used to detect pathological changes in tissue for a variety of clinical applications, including identification of edema and iron overload. The most widely used T2 mapping pulse sequence is the Carr-Purcell-Meiboom-Gill (CPMG) sequence [1,2]. For body MRI, however, a CPMG pulse sequence is typically performed with navigat...

In this article. rhe approach developed by the authors for systematicallv studving rhe acceleration capabiliry and properties of rhe end effector of a planar manipulator is extended to the general. serial, spatial manipulator possessing three degrees of freedom. The acceleration of the end effector at a given configuration of the manipulator is a linearfunction of the actuator rorques and a (no...

This paper introduces latency mapping as a technique for visualising surveillance coverage. Built on a concept for modelling the total effort by a surveillance force, latency mapping provides an understanding of the collective sensor coverage against a region of interest, in space and time. Latency mapping has been used to support the analysis of maritime surveillance operations in Australia’s ...

We present in this paper models and statistical methods for performing multiple trait analysis on mapping quantitative trait loci (QTL) based on the composite interval mapping method. By taking into account the correlated structure of multiple traits, this joint analysis has several advantages, compared with separate analyses, for mapping QTL, including the expected improvement on the statistic...

Spectral unmixing and sub-pixel mapping have been used to estimate the proportion and spatial distribution of the different land-cover classes in mixed pixels at a sub-pixel scale. In the past decades, several algorithms were proposed in both categories; however, these two techniques are generally regarded as independent procedures, with most sub-pixel mapping methods using abundance maps gener...

The kinematic mapping x = f(&thetas;) is generally many to one. For nonredundant manipulators, this means that there are a finite number of configurations (joint angles) that will place the end-effector at a target location in the workspace. These correspond to postures of the manipulator, and each configuration lies on a specific solution branch. It is shown that for certain classes of revolut...
