Ιατρικά Άρθρα Αλέξανδρος Γ. Σφακιανάκης: Bearing Fault Detection by One-Dimensional Convolutional Neural Networks
Bearing faults are the biggest single source of motor failures. Artificial Neural Networks (ANNs) and other decision support systems are widely used for early detection of bearing faults. The typical decision support systems require feature extraction and classification as two distinct phases. Extracting fixed features each time may require a significant computational cost preventing their use in real-time applications. Furthermore, the selected features for the classification phase may not represent the most optimal choice. In this paper, the use of 1D Convolutional Neural Networks (CNNs) is proposed for a fast and accurate bearing fault detection system. The feature extraction and classification phases of the bearing fault detection are combined into a single learning body with the implementation of 1D CNN. The raw vibration data (signal) is fed into the proposed system as input eliminating the need for running a separate feature extraction algorithm each time vibration data is analyzed for ...

Integrity Monitoring in Navigation Systems: Fault Detection and Exclusion RAIM Algorithm Implementation
The use of GPS is becoming increasingly popular for real-time navigation systems. To ensure that satellite failures are detected and excluded at the receiver is of high importance for the integrity of the satellite navigation system. The focus of this paper is to implement a fault detection and exclusion algorithm in a software GPS receiver in order to provide timely warnings to the user when it is not advisable to use the GPS system for navigation. The GPS system currently provides some basic integrity information to users via the navigation message, but it is not timely enough for safety-critical applications. RAIM is a means of providing integrity with the capability of detecting when a satellite failure or a measurement error has occurred. It is the simplest and most cost effective technique for integrity monitoring. After applying the iterative fault detection and the exclusion algorithm, a significant improvement in positioning accuracy is achieved.

Patent US6532424 - Electrical fault detection circuit with dual-mode power supply - Google Patents
An arcing fault protection assembly and a corresponding method determine whether arcing is present in electrical circuits. The assembly powers-up quickly without dissipating excessive heat while power is being supplied to the assembly. The assembly comprises a sensor, a broadband noise circuit, a controller, and a dual-mode power supply. The sensor detects a current flowing in an electrical circuit and develops a corresponding sensor signal. The broadband noise circuit determines the presence of broadband noise in the sensor signal and produces a corresponding output signal. The controller processes the sensor signal and the output signal in a predetermined fashion to determine whether an arcing fault is present in the circuit. The dual-mode power supply supplies power to the sensor, broadband noise circuit and controller using a first mode and later switching to a second mode. The first mode reaches steady state faster than the second mode.

Hardware-in-the-Loop Prototype of a Negative Sequence Based Scheme for Turn-to-Turn Fault Detection in Transformers
During the course of a transformers operational life, it experiences many challenges to its insulation. Chemical stresses, such as moisture in insulating oil, deteriorate insulation chemically. Mechanical stresses and thermal stresses, such as those experienced during a large external fault, also contribute to weakening a transformers insulation. Once these stresses have weakened the insulation to the point of breakdown, a fault may occur between windings of the transformer. These faults, known as turn-to-turn faults, are difficult to detect electrically at the terminals of the transformer until they have grown to the point of damaging the transformer beyond repair. Current differential transformer protection is a simple, reliable, and cost effect method of detecting turn-to-turn faults. This method of protection is only able to detect faults involving 10% of the windings or more. The sensitivity of current differential protection is limited as not to cause false tripping due to normal ...

Improving product quality is always of industrial interest. Product availability, a function of product maintainability and reliability, is an example of a measurement that can be used to evaluate product quality. Product availability and cost are two units which are especially important to manage in the context of the manufacturing industry, especially where industry is interested in selling or buying offers with increased service content. Industry in general uses different strategies for increasing equipment availability; these include: corrective (immediate or delayed) and preventive strategies. Preventive strategies may be further subdivided into scheduled and predictive (condition-based) maintenance strategies. In turn, predictive maintenance may also be subdivided into scheduled inspection and continuously monitored. The predictive approach can be achieved by early fault detection. Fault detection and diagnosis methods can be classified into three categories: data-driven, analytically ...

Robust sensor fault estimation for descriptor-LPV systems with unmeasurable gain scheduling functions: application to an...
This paper addresses the design of a state estimation and sensor fault detection, isolation and fault estimation observer for descriptor-linear parameter varying (D-LPV) systems. In contrast to where the scheduling functions depend on some measurable time varying state, the proposed method considers the scheduling function depending on an unmeasurable state vector. In order to isolate, detect and estimate sensor faults, an augmented system is constructed by considering faults to be auxiliary state vectors. An unknown input LPV observer is designed to estimate simultaneously system states and faults. Sufficient conditions to guarantee stability and robustness against the uncertainty provided by the unmeasurable scheduling functions and the influence of disturbances are synthesized via a linear matrix inequality (LMI) formulation by considering H∞ and Lyapunov approaches. The performances of the proposed method are illustrated through the application to an anaerobic bioreactor model ...

ADVANCED ENDOSCOPIC POLYPECTOMY SKILLS ACQUISITION VIA A NOVEL BENCH-TOP TRAINING PROGRAM. - SAGES Abstract Archives
Yohei Kono1, Kota Momose1, Talal Alzghari1, Reem Alharbi2, Patrick Dolan1, Jackly Juprasert1, Russell Corwin1, Andrew Harvey1, Takahiro Hiratsuka3, Jeffrey Milsom1, Sam K Sharma1. 1Weill Cornell Medicine, 2Princess Nourah bint Abdulrahman University, 3Oita University. Introduction: Hypothesis - to determine whether a bench-top combination training model and program could lead to the acquisition of advanced ESD skills in a group of trainees of varying endoscopic experience.. Complex endoscopic skills needed for procedures such as ESD require stepwise training methods to build confidence and neuromuscular pathways (muscle-memory). The lack of suitable Western training models/methods may partly account for ESDs relatively low uptake. In Japan, ESD training follows a program of increased difficulty leading to operator competence. We aimed to simulate some of these core principles in our model and training program.. Methods: We constructed a 3-D printed abdomino-pelvic housing into which we ...

Consider process-based failure analysis methods for piping and equipment
Avoiding incident (or accident) recurrences at industrial systems is a long-standing problem, and it involves process safety strategies (PSSs). Incurring zero incidents is the ultimate goal for any structured failure analysis. When applied to pipes and equipment, this investigation usually involves studying the damage mechanisms. Sometimes it requires deep and complex laboratory testing. Often, it is just based on team experience, visual inspection, design, codes, and process and maintenance information. However, the physical approach to failure analysis, which identifies the type of corrosion, metallurgical alteration or mechanical damage, is not conclusive or sufficient enough to avoid. ...

Stress-field rotation and rooted detachment faults: A Coulomb failure analysis | Lamont-Doherty Earth Observatory
Several well-known mechanical models have shown that unusual boundary or loading conditions can alter principal-stress orientations into configurations consistent with low-angle normal faulting. Such models, however, have not demonstrated whether magnitudes of reoriented stresses are sufficient to initiate and promote slip on low-angle surfaces. We present the results of simple Coulomb failure analyses to determine whether, and where, such models predict frictional slip, assuming geologically plausible boundary stresses, pore pressures, and rock strengths. Models that invoke a sizable shear traction at the base of the upper crust or spatially varying loads on the upper crust reorient principal stresses and failure planes but do not produce frictional failure on crustal-scale detachments either in the absence of pore fluids or at hydrostatic pore fluid pressures. Models that reorient stresses by midcrustal dike intrusion produce slip on low-angle surfaces at relatively deep crustal levels but ...

American Society for Metals [WorldCat Identities]
Detailed analyses of failures of material components have proved to be valuable in many ways; by preventing further failures, by assessing the validity of designs and the selection of materials, by uncovering shortcomings in the processing of the materials in- volved through characterizations of defects, and by revealing problems introduced during the manufacture or fabrication of the component. Increased recognition of the value of performing failure analyses has caused the field to develop into a very active area of tech- nical endeavor. Failure analysis has been employed in numerous different technical dis- ciplines and has proven beneficial. The increased activity has caused many new and im- proved methods for performing these analyses to be developed. Among these are many methods which can be characterized as generally belonging to the field of metallography. In recognition of the important role that metallography plays in the performance of failure analyses, the absence of a text that ...
The analysis of errors is a complex process that applies to all the various types of supplies. Each group of materials requires special skills and adequate experimentation to solve effectively the causes of failure. The objective of the analysis of errors is entirely positive: to avoid additional late failures. Amazing restaurateur has much experience in this field. The determination of the errors that occur when a structure or part of a structure does not meet the expectations for which has been avoiding economic and personal costs in the future. The hypothesis of failure is easy to understand intuitively. But beneath that intuitive understanding there are crucial conceptual principles that are commonly misunderstand or not considered at all. Shimmie horn has many thoughts on the issue. One usual aspect of failure analysis is associated with No Failure Found (without errors), is a term used in the field of failure analysis to explain a situation in which initially reported a possible bug in a ...

CDC - Mining - Technology News 456 - A Fault Detection Neural Network - NIOSH
DC trolley haulage systems move personnel supplies, and coal in approximately 50 U.S. mines. A suspended trolley line energized at 300 or 600 V dc provides electrical power, and a system of steel track serves as the return path. When roof falls and other events force the trolley line down near the ground return rail, inductance inherent in the trolley system facilitates continued current flow along an ionized path between the line and rail. This releases a significant amount of energy in the arc and may damage and/or ignite surrounding material. Conventional circuit breaker systems cannot prevent this continued arcing because the magnitudes of the currents involved may be significantly less that typical breaker trip settings. In 1980, the former U.S. Bureau of Mines demonstrated research to detect arcing and other types of trolley faults. The system required an oscillator to superimpose a 3-kHz signal in the trolley line, a signal wire suspended parallel to the trolley line fore circuit breaker ...

UAH - Reliability and Failure Analysis Laboratory - E-Glass Composites
The Reliability and Failure Analysis Lab has developed a method for characterizing E-glass composite materials with fiber distortion. Manufacturing methods were developed to produce quality samples. The material used was a pre-impregnated fiberglass, epoxy-phenolic matrix, composite material. This basically means the resin must undergo a thermal process to attain its final strength.. Each sample was created by cutting strips of the pre-preg tape from a large roll to a desired length. The material was then sorted by aligning the tracer fibers of the material and consolidating every 10 layers under a vacuum. The final laminate was composed of 110 layers of the e-glass epoxy material with an inserted defect. After consolidation was finished the pre-processed laminate was put into an aluminum mold with a pressure plate. The mold was placed into a vacuum bag and inserted into the autoclave to undergo a programmed heat/pressure cycle.. There is an ideal volume ratio of approximately 60% fiber to 40% ...
