Reliability Demonstration Testing (RDT) for non-repairable systems has been successfully implemented in many industries, such as microelectronics, aerospace and healthcare. In designing RDTs, the famous beta-binomial formula is often applied to determine the necessary sample size so that the required reliability metric at a given confidence level can be demonstrated. However, many systems, such as...
Orthogonal experimental design in general belongs to a single target design, using conventional visual analysis and variance analysis to select the best and the most influential factors combination. However, in actual production, the product needs more than one indicator to be inspected, belonging to multi-index test design, and each index on the influence degree of product performance is different,...
The design of experiments will help to underline the influence of combined operating constraints in insulation reliability of low voltage electrical machines in aerospace applications in the more electric aircraft. Kapton films and coated wires were subjected to an accelerated ageing under combined stresses (VRMS, frequency, DC voltage, and temperature). It is shown in this paper, that the parameters...
A low power reconfigurable DCT architecture is proposed, which can be run at three transform precision levels for different demands. Using the character of energy distribution of the DCT matrix after 2D DCT operation, we selected the best DCT bases which achieve considerable power reduction in DCT operation with minimum image quality degradation. The reconfigurable architecture can achieve power saving...
In conventional optical data transmission schemes, electrical filters and/or optical filters are used to improve the quality of system performance. In this paper, improved design of dense wavelength division multiplexing (DWDM) optical systems is achieved by using a selective electrical filter assignment method. The methodology objective is to optimize system design and mitigate the effects of fiber...
A speed independent circuit has the property that the relative speed of operation of the various logic elements does not affect the over-all behavior of the circuit. Such circuits have properties which are of particular importance in the design of reliable asynchronous circuits. An Arithmetic Control for a digital computer is one type of logic which can profitably use these characteristics. The design...
