Inhibiting mTTR Aggregation/Fibrillation by a Chaperone-like Hydrophobic Amino Acid-Conjugated SPION
Journal of Physical Chemistry B, 2022 Transthyretin (TTR) aggregation via misfolding of a mutant or wild-type protein leads to systemic or partial amyloidosis (ATTR). Here, we utilized variable biophysical assays to characterize two distinct aggregation pathways for mTTR (a synthesized monomer TTR incapable of association into a tetramer) at pH 4.3 and also pH 7.4 with agitation, referred ...

MTTR Grouping Verification Based on Similarity
Applied Mechanics and Materials, 2010 Traditional verification method is not suitable for complex equipment MTTR verify directly for they are more integrative and modularized. A method for group-verification is brought up which comprises sub-system of the complex equipment based on degree of similarity of MTTR curve. Determine similarity degrees of curves.

Availability, MTBF and MTTR for Repairable M out of N System
IEEE Transactions on Reliability, 1981The availability of a redundant system requiring m out of n units to be operational represents a basic and elementary result within reliability engineering. The corresponding mean time between system failures (MTBF) and mean time of system restoral (MTTR) are less commonly known since these results have either required the solution of time-dependent ...

Researches on integrated evaluation methods for military aircraft's MTTR
The Proceedings of 2011 9th International Conference on Reliability, Maintainability and Safety, 2011Exerting combat efficiency of military aircraft relies heavily on its own quality characteristics, such as reliability, maintainability and supportability. Reducing aircraft's Mean Time To Repair (MTTR) is one of the significant targets for the maintenance of military aircraft to concern.

Analysis of MTBF/MTTR for Logistics Service System
ICTE 2013, 2013Mean Time Between Failures/Mean Time to Repair (MTBF/MTTR) are important parameters for measuring the reliability of systems. Shorter MTBF/MTTR normally means high service quality. However, a reasonable level of reliability is usually not defined. In this paper, the calculation method of MTBF/MTTR is presented.

A Maintenance Modeling for Evaluating MTTR of Complex Systems Based on Goal Orient Method
2017 International Conference on Sensing, Diagnostics, Prognostics, and Control (SDPC), 2017This paper proposes a new maintenance modeling for evaluating Mean Time To Repair (MTTR) of complex systems based on Goal Orient (GO) method. First, the GO operation formulas of MTTR for the frequently-used GO operators are proposed. Then, the system MTTR evaluation process of this paper' method is formulated.

Computing Failure Frequency, MTBF & MTTR via Mixed Products of Availabilities and Unavailabilities
IEEE Transactions on Reliability, 1981In many practical situations system availability or unavailability is found or given as a polynomial with terms which are mixed products of availabilities and unavailabilities of the components. Starting with such a polynomial, considerable algebraic manipulation has been considered to be necessary before the failure frequency could be determined. Here
