Retraction of “Mechanical Reconfiguration of Stereoisomers”

Journal of the American Chemical Society, 2015
Poly(methyl acrylate) of varying molecular weight was grown from the enantiopure ditopic initiator (R)- or (S)-1,1′-binaphthyl-2,2′-bis-(2-bromoisobutyrate). Subjecting CH3CN solutions of high-molecular-weight derivatives (MN > 25 kDa) to sonication at 0 °C resulted in >95% racemization after 24 h, as determined by circular dichroism; no appreciable ...

Systematization of morphing in reconfigurable mechanisms

Mechanism and Machine Theory, 2016
Abstract This paper addresses metamorphic and reconfigurable mechanisms based on types of morphing and ways of achieving it through a comprehensive review and a classification of mechanisms in the literature while considering various types of morphing.

Reconfiguration Method for a Distributed Mechanical System

1996
A novel design method for a mechanical system is proposed and a prototype model of the system is shown in this paper. Conventional mechanical systems are composed of various parts which are passive. In the new scheme, they are made with only one kind of active and intelligent units.

Reconfiguration of Spatial Metamorphic Mechanisms

Journal of Mechanisms and Robotics, 2008
This paper investigates reconfiguration of metamorphic mechanisms as a typical character of topological change of the mechanisms. Metamorphic mechanisms with reconfigurable topology provide changed topological states and subsequently change the mobility to give various subphase mechanisms.

Fundamental reconfiguration theory of chain-type modular reconfigurable mechanisms

Mechanism and Machine Theory, 2013
Abstract This article focuses on the study of geometry constraints, motion sequence, isomorphism and interference issues of the chain-type modular reconfigurable mechanisms. The geometry representation of module is accomplished by employing the Clifford algebra.

Dynamic Reconfiguration of Parallel Mechanisms

2010
Shorter product life cycle as well as higher product complexity and diversity require more flexible manufacturing systems. Dynamic reconfiguration is a time efficient way to adapt system properties to rapidly changing process requirements. The potential to reconfigure parallel mechanisms depends on specific and optimized machine components, which ...

Carpie: A soft, mechanically-reconfigurable worm robot

2019 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS), 2019
Soft robots are a burgeoning archetype in robotics due to their ability to perform intricate movements easily and seamlessly. They serve as an ideal concept for realistically emulating animal movements. However, the majority of soft robots today are unable to vary their motions due to the coupled interaction of the nature of their kinematics and ...

Reconfiguration mechanism for an IP block based interconnection

Proceedings 25th EUROMICRO Conference. Informatics: Theory and Practice for the New Millennium, 1999
This paper presents a reconfiguration mechanism for an on-chip interconnection scheme called Heterogeneous IP Block Interconnection (HIBI). Required memory structures and logical signal operations for the different configurations are explained. The possible applications for this kind of reconfiguration are discussed, including ways to enhance system ...

Mechanically Reconfigurable Polarization Converter for Terahertz Waves

IEEE Transactions on Terahertz Science and Technology
In terahertz systems, polarization conversion is usually carried out using conventional waveplates. However, limitations in these waveplates arise from inadequate material accessibility, relatively narrow bandwidth, low efficiency, and bulkiness. To overcome these limitations, a transmissive terahertz metasurface with mechanically reconfigurable ...
