Sequence Manipulation Using Parallel Mapping Networks
Neural Computation, 1991We describe a parallel mapping matrix that performs several types of sequence manipulations that are the building blocks of well-known phonological processes. Our results indicate that human phonological behavior can by modeled by a highly constrained connectionist architecture, one that uses purely feedforward circuitry and imposes tight limits on ...

TOPOLOGICAL SYNTHESIS OF TRANSLATIONAL PARALLEL MANIPULATORS
Transactions of the Canadian Society for Mechanical Engineering, 2009For translational parallel manipulators (TPMs), topology synthesis methods that can be found in the literature are mainly based on screw theory, instantaneous kinematics, or group theory. In this work, finite displacement equations are used for the topology synthesis of TPM.

Force Transmissibility Performance of Parallel Manipulators
Journal of Robotic Systems, 2003AbstractIn this paper, a new force transmission index called the mean force transmission index (MFTI) is proposed, and the force transmissibility analysis procedure is established for parallel manipulators. TheMFTIis an extended definition of the force transmission index (FTI) introduced by the authors previously.

A Translational 3-dof Parallel Manipulator
1998This paper presents a new architecture of a three degree-of-freedom parallel manipulator that, if properly assembled, exhibits pure translational motion of the output link (platform) with respect to the frame (base). To prove the existence of a pure translational motion a mobility analysis of the manipulator has been carried out.

3RRRS+3RRPS Parallel Manipulator
2016The combination of rotary and linear actuators in a parallel manipulator is an interesting option to overcome some of its limitations, such as its well-known limited workspace and recurrent problem of singular configurations. This chapter uses screw theory to address the kinematics of a six-degree-of-freedom parallel manipulator provided with a ...

This chapter reports on the kinematics of a symmetric three-legged six-degree-of-freedom parallel manipulator equipped with a combination of rotary and linear actuators. The introduction of this class of robot manipulators has been a recursive option to avoid the complexity of the forward displacement analysis of the general hexapod.

Architecture Singular Parallel Manipulators
1998In the classification problem of architecture singular parallel manipulators there is a qualitative difference between the planar and non-planar cases. The classification of planar ones was already given in (Karger, Husty, 1997), this contribution is devoted to the non-planar case.

Direct manipulation of parallel coordinates
CHI '00 extended abstracts on Human factors in computer systems - CHI '00, 2000This paper introduces two novel techniques to manipulate parallel coordinates. Both techniques are dynamic in nature as they encourage one to experiment and discover new information through interacting with a data set. The first technique, polyline averaging, makes it possible to dynamically summarise a set of polylines and can hence replace ...
