Two-dimensional failure modeling with minimal repair

Maintenance Cost Analysis for Replacement Model with Perfect Minimal Repair

With the evolution of technology, the maintenance of sophisticated systems is of concern for system engineers and system designers. The maintenance cost of the system depends in general on the replacement and repair policies. The system replacement may be in a strictly periodic fashion or on a random basis depending upon the maintenance policy. At failure, the repair of the system may be perfor...

Three-dimensional modeling from two-dimensional video

This paper presents the surface-based factorization method to recover three-dimensional (3-D) structure, i.e., the 3-D shape and 3-D motion, of a rigid object from a two-dimensional (2-D) video sequence. The main ingredients of our approach are as follows: 1) we describe the unknown shape of the 3-D rigid object by polynomial patches; 2) projections of these patches in the image plane move acco...

Failure Process Modeling with Censored Data in Accelerated Life Tests

Manufacturers need to evaluate the reliability of their products in order to increase the customer satisfaction. Proper analysis of reliability also requires an effective study of the failure process of a product, especially its failure time. So, the Failure Process Modeling (FPM) plays a key role in the reliability analysis of the system that has been less focused on. This paper introduces a f...

Modeling Two-dimensional Fluid Flows with Chaos Theory

xperiments at the Applied Physics Laboratory have shown that chaos theory can be used to quantitatively model two-dimensional fluid flows. These results support the utility, under some circumstances, of low-degree-of-freedom approaches to the theoretically infinite-degree-of-freedom phenomena described by the Navier–Stokes equations. However, the types of predictions made by chaos theory are fu...
