Reconfigurable Microkernel-based RTOS: Mechanisms and Methods for Run-Time Reconfiguration

2006 IEEE International Conference on Reconfigurable Computing and FPGA's (ReConFig 2006), 2006
The requirements of high computational performance and flexibility of the contemporary embedded systems are continuously increasing. Moreover, a single architecture must be able to support different applications with dynamical requirements (changing environments).

Mechanism State Matrices for Planar Reconfigurable Mechanisms

Journal of Mechanisms and Robotics, 2011
This paper introduces mechanism state matrices as a novel way to represent the topological characteristics of planar reconfigurable mechanisms. As part of this new approach, these matrices will be used as an analysis tool to automatically determine the degrees of freedom (DOFs) of planar mechanisms that only contain one DOF joint. The DOF at each state

Optimization of Reconfiguration Mechanisms in Critical Infrastructures

2015
Recently, the protection of critical infrastructures became a core problem due to their importance in the everyday life and the attacks that may affect these systems. In order to ensure the safety and the efficient operation of such systems, a method together with an integrated framework is proposed to find a solution to the problem to deliver a system

Reconfigurable Generalized Parallel Mechanisms with Kinematotropic Linkages

2021 7th International Conference on Mechatronics and Robotics Engineering (ICMRE), 2021
This paper presents a novel idea of designing reconfigurable generalized parallel mechanisms (GPMs) by integrating kinematotropic linkages with coupling sub-chains (CSs) or configurable platforms (CPs). This leads to two brand-new ways of constructing reconfigurable mechanisms.

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.

A mechanically pattern reconfigurable array

Microwave and Optical Technology Letters, 2019
AbstractA design of pattern reconfigurable arrays realized with mechanical mechanism is presented. The radiating element of the array is a printed dipole backed with a metallic box, and it has a broad impedance bandwidth as well as a high front‐to‐back ratio. Four of the elements are connected together by using a mounting fixture with rotatable joints.

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.
