A concurrent optimization model for suppliers selection, tolerance and component allocation with fuzzy quality loss

Cogent Engineering, 2016
The aim of this paper is to develop an optimization model to optimally select suppliers and allocate components to the selected suppliers. The objectibve function of the model is to minimize purchasing cost and fuzzy quality loss.

Fault Tolerant Mechanism Design for General Task Allocation [PDF]

International Joint Conference on Autonomous Agents and Multiagent Systems, 2016
We study a general task allocation problem, involving multiple agents that collaboratively accomplish tasks and where agents may fail to successfully complete the tasks assigned to them (known as execution uncertainty). The goal is to choose an allocation that maximises social welfare while taking their execution uncertainty into account (i.e., fault ...

Neuromorphic Devices for Extreme Environments: State‐Variable Reliability and Stabilization Strategies

Advanced Functional Materials, EarlyView.
Neuromorphic devices for extreme environments are interpreted through the physical states that store and process information. Radiation, temperature extremes, and vacuum can perturb vacancies, filaments, trapped charges, polarization, interfaces, and readout signals.

Reliable Multiservice Delivery in Fog-Enabled VANETs: Integrated Misbehavior Detection and Tolerance

IEEE Access, 2019
Vehicular ad hoc networks (VANETs) in which vehicles act as the mobile nodes provide a wide variety of services, such as audio and video surveillance. However, such networks suffer from an important problem of service delivery reliability as the network ...

Ultra‐Thin Tow‐Based Discontinuous Composites—Material Overview and Aspirations

Advanced Functional Materials, EarlyView.
Tow‐based discontinuous composites made from ultra‐thin tapes offer outstanding in‐plane mechanical properties. This material, inspired by Nacre, has high volume fraction of tapes exceeding 90 % and allows for quasi‐isotropic material plates less than 100 micrometer in thickness.

Dynamic Physicochemical Gradients for Tendon–Bone Regeneration

Advanced Functional Materials, EarlyView.
Dynamic physicochemical gradients offer a framework for reconnecting soft tendon and hard bone. This Review examines how hydration, transport, loading and degradation reshape these gradients during healing. Coordinating regional biological cues with progressive transfer of load from scaffold to tissue guides the design of interfaces that retain ...

A Triboelectric‐Hydrogel System for Mechano‐Metabolic Re‐Coupling in Skin Expansion: Recharging From Energy Crisis

Advanced Healthcare Materials, EarlyView.
Progressive skin expansion creates an energy crisis that compromises regenerative capacity. A self‐powered triboelectric‐hydrogel system (TP‐PAM/G) re‐couples mechanical loading with cellular metabolism by combining motion‐generated electrical stimulation and stress redistribution.

Establishment of a Responsive Tooth‐on‐a‐Chip Platform for the Assessment of Regenerative Factors in Dental Tissue Regeneration

Advanced Healthcare Materials, EarlyView.
Using a tooth‐on‐a‐chip model that recreates interactions between dental epithelial and mesenchymal cells, the authors show that sequential FGF10+BMP4, BMP2, and Emdogain produce distinct, biologically consistent regenerative responses. The platform recapitulates known signal‐specific effects and, for the first time, reveals an influence of Emdogain on

Error modeling and tolerance design of a parallel manipulator with full-circle rotation

Advances in Mechanical Engineering, 2016
A method for improving the accuracy of a parallel manipulator with full-circle rotation is systematically investigated in this work via kinematic analysis, error modeling, sensitivity analysis, and tolerance allocation. First, a kinematic analysis of the
