Forecasting failure rate of water pipes
, 2019 This paper presents the results of failure rate prediction by means of support vector machines (SVM) – a non-parametric regression method. A hyperplane is used to divide the whole area in such a way that objects of different affiliation are separated ...

On ageing properties of lifetime distributions [PDF]
arXiv, 2021 A reasonable segment of reliability theory is perpetrated to the study of failure rates, their properties, connections and applications. The present study focused on failure rate distributions and their shape properties. Failure rates of various generalizations of Lindley distribution are discussed and the distinguishable roles of DUS transformation is

Failure rates in introductory programming [PDF]
ACM SIGCSE Bulletin, 2007 It is a common conception that CS1 is a very difficult course and that failure rates are high. However, until now there has only been anecdotal evidence for this claim. This article reports on a survey among institutions around the world regarding failure rates in introductory programming courses.

Model of correlation between geometry of thermoelectric branches and reliability indicators of single-stage coolers in Q0max mode [PDF]
Tekhnologiya i Konstruirovanie v Elektronnoi Apparature, 2016 The authors consider the influence of the geometry of thermoelectric branches on the performance reliability of single-stage thermoelectric devices (TED) operating at maximum cooling capacity at 2.0 W thermal load for any values of temperature difference

Modeling Soft-Failure Evolution for Triggering Timely Repair with Low QoT Margins [PDF]
, 2022 In this work, the capabilities of an encoder-decoder learning framework are leveraged to predict soft-failure evolution over a long future horizon. This enables the triggering of timely repair actions with low quality-of-transmission (QoT) margins before a costly hard-failure occurs, ultimately reducing the frequency of repair actions and associated ...

Credit Ratings Failures and Policy Options [PDF]
Economic Policy, 2010 This paper examines the role of credit rating agencies in the subprime crisis that triggered the 2007-2008 financial turmoil. We focus on two aspects of ratings that contributed to the boom and bust of the market for structured debt: rating inflation and coarse information disclosure. The paper discusses how regulation can be designed to mitigate these

Damage Rate Laws and Failure Statistics for Lumped Coupled-Field Systems via Averaging [PDF]
arXiv, 2023 We study the non-linear dynamics and failure statistics of a coupled-field fatigue damage evolution model. We develop a methodology to derive averaged damage evolution rate laws from such models. We show that such rate laws reduce life-cycle simulation times by orders of magnitude and permit dynamical systems analysis of long-time behavior, including ...

Failure Rate Estimation in a Dynamic Environment [PDF]
Economic Quality Control, 2015 Abstract We present a method to assess the reliability of a material operating in a dynamic environment. The dynamic environment is represented as a sequence of shocks governed by a self-exciting point process. The time-to-failure of the material is assumed to have a piecewise exponential distribution.
