, Stanton, and Whitelaw (1997), who find that a 3-factor model explains over 90 percent of Ginnie Mae yields, but that the remaining variation apparently cannot be explained by the changes in the yield curve. 2 In contrast, our multiple-factor model explains only about one-quarter of the variation in credit

Remaining useful life (RUL) prediction is one of key technologies to realize prognostics and health management that is being widely applied in many industrial systems to ensure high system availability over their life cycles. The present work proposes a data-driven method of RUL prediction based

Prognostics activity deals with the estimation of the Remaining Useful Life (RUL) of physical systems based on their current health state and their future operating conditions. RUL estimation can be done by using two main approaches, namely model-based and data-driven approaches. The first approach

This paper presents a vibration method for remaining life estimation of components in washing machines. Vibration signals were measured on electric motors during an accelerated lifetime test. Significant frequency bands are identified using a spectral comparison based on the Constant Percentage

In this paper, the estimation of the Residual Useful Life (RUL) of degraded thrust ball bearings is made resorting to a data-driven stochastic approach that relies on an iterative Naïve Bayesian Classifier (NBC) for regression task. NBC is a simple stochastic classifier based on applying Bayes

model, in addition to being the first to realize fully anonymous HIBE at all levels in the hierarchy. Introduction The cryptographic primitive of identity-based encryption allows a sender to encrypt a message for a receiver using only the receiver's identity as a public key. Recently, there has

to perform a useful function it is phased out from the network, and the network rearranges itself -as cells do in biological processes. Some nodes are more important than others, but they all need each other as long as they are within the network. And no nodal domination is systemic. Nodes increase

ABSTRACT: Condition monitoring is used to frequently monitor the parts of an engine. Since the failures are predicted in advance, the lifetime of the machine is increased, thereby minimizing the maintenance costs. Among the many techniques used for condition monitoring such as static, dynamics

The estimation of remaining useful life (RUL) of a faulty component is at the center of system prognostics and health management. It gives operators a potent tool in decision making by quantifying how much time is left until functionality is lost. This is especially true for aerospace systems

UV fluorescence is commonly used as a first-pass visualisation tool for the study of Hydrocarbon bearing Fluid Inclusions (HCFI). Fluorescence colour is commonly used as a guide to estimate API gravity (Bodnar, 1990) and allow visual discrimination of single or multiple HCFI generations into a
