24 apr 2019 this recall of error phenomenon suggests that our unconscious minds constantly sift through what has happened; they can then go into alarm.
The phenomenon of individual latent error detection (i-led) is proposed. Iled refers to the detection of workplace latent errors at some point post-task.
Latent threats lastly, some threats may not be directly obvious to, or observable by, flight crews immersed in the operational context, and may need to be uncovered by safety analysis. Examples of latent threats include equipment design issues, optical illusions, or shortened turn-around schedules.
Latent errors are sometimes referred to as errors at the blunt end, referring to the many layers of the health care system that affect the person holding the scalpel. Active failures, in contrast, are sometimes referred to as errors at the sharp end, or the personnel and parts of the health care system in direct contact with patients.
A framework configured to execute one or more of the plurality of modules for each type of component as a low priority background task, wherein each module of the plurality of modules is separately pluggable within said framework;.
Program executions, and thereby to discover errors in pro-gram source code. Once a program passes all the tests in its test suite, testing no longer leads programmers to errors. However, the program is still likely to contain latent errors, and it may be difficult or expensive to generate new test cases that reveal additional faults.
Individual latent error detection (i-led) has been observed where errors suffered by naval air engineers at work appear to be later detected spontaneously by the individual at some point post-task completion, and without reference to recognised procedures (saward and stanton, 2015).

Does not allow modeling the probability density of individual pixels but works with the whole image. It is not suitable for image compression, and while its generative nature allows in principle to produce novel images, in this work we focus only on novelty detection by evaluating the inlier probability distribution on test samples.
According to the health and safety executive (hse) human errors can be active or latent. Active failures are direct and immediate causes of an accident, and are usually made by front-line staff such as drivers or machine operators.
Errors are defined as “individuals' decisions and behaviors that (1) result in an near misses, active errors, and latent errors” (thomas and petersen, 2003).
9 sep 2014 how do we handle validation of tsn streams and latent error detection? • see slides, below, for one suggestion.
The swiss cheese model of accident causation is a model used in risk analysis and risk the holes in the slices represent weaknesses in individual parts of the system and are latent failures span the first three domains of failure.
Rca thus uses the systems approach to identify both active errors (errors occurring at the point of interface between humans and a complex system) and latent errors (the hidden problems within health care systems that contribute to adverse events). It is one of the most widely used retrospective methods for detecting safety hazards.

Such errors are typically not detected until an attempt is made to read the affected sectors.
(1,2) latent errors (or latent conditions) refer to less apparent failures of of the safety management system that affect the person carrying out the task. Root cause with side effects; side effects are considered detected errors.
Blaming an individual does not change these factors and the same error is in medicine might involve selecting the wrong drug because the diagnosis is wrong. Latent errors pose the greatest threat to safety in a complex system beca.
Latent errors may lie dormant in systems for some time, but given a certain set of circumstances become evident. They are usually the result of decisions made by managers and administrators, designers of equipment and maintenance staff. In a sense, latent errors “set the scene” to make it more likely that an active error will occur.
Concern are latent sector errors (lses), where individual sectors on a drive become unavailable. Lses are caused, for example, by write errors (such as a high-fly write) or by media imperfections, like scratches or smeared soft particles. There are several reasons for the recent shift of attention to lses as a critical factor in data reliability.

17 sep 2018 we introduce latent factor analysis via dynamical systems, a deep learning but deeper understanding requires studying phenomena detected in single trials, epoch of data was greater than the last six training error.
3 dec 2020 we rigorously prove that reversibility augments the performance of this simple error detection protocol to a considerable degree.
Individual latent error detection (i-led) acts as an additional system safety control that helps an engineer recall past errors through environmental cues. This book addresses a gap in the human factors research and current safety strategies by exploring the nature and extent of i-led and its benefit to safety resilience.
