2020-7-15Three types of faults are discussed: static eccentricity turn-to-turn short circuit and partial demagnetization fault Two-dimensional finite element analysis (FEA) is used to model and simulate the machine under healthy and faulted conditions
One of the major and serious threats on the Internet today is malicious software often referred to as a malware The malwares being designed by attackers are polymorphic and metamorphic which have the ability to change their code as they propagate Moreover the diversity and volume of their variants severely undermine the effectiveness of traditional defenses which typically use signature

Condition monitoring (CM) and fault diagnosis of equipments has gained greater attention in recent years due to the need to reduce the down time and enhance the life/ condition of the equipments The rolling element bearings (REB) are the most critical components in rotary machines Hence bearing fault detection and diagnosis is an integral part of the preventive maintenance activity
2013-1-1Among these vibration signature analysis is the one which is widely used as it provides important information about anomalies formed in the internal structure of the bearing [1] of the DWT contain high-frequency noise components along with some of the characteristic information of the machine fault [11] Suitable compression or suppression

2014-6-22Such faults may have an effect on the machine itself but may also lead to accidents at work Thus the activities aiming at the identification of the relation between the failure causes and their effects seem to be necessary to be undertaken With this purpose the first part of the paper concerns the analysis of machine faults

During the mission at sea the ship steering control to yaw motions of the intelligent autonomous surface vessel (IASV) is a very challenging task In this paper a quantum neural network (QNN) which takes the advantages of learning capabilities and fast learning rate is proposed to act as the foundation feedback control hierarchy module of the IASV planning and control strategy The numeric
2014-1-11 Introduction Signature analysis has been widely used for digital and mixed-signal systems testing [1-12] Mixed-signal systems consist of both digital and analog circuits however the signature analysis method is only applicable to the subset of these systems that have digital outputs (such as analog-to-digital converters measurement instruments etc )

It can be seen from the reduction algorithm that the results can have multiple reductions and here the red(P) is the candidate set of fault associativities Which red(P) will be chosen for a fault depended on the highest accuracy of the fault diagnosis model trained by P i Supposing the faults set F = {f 1 f 2 f 3} the red(P) = {P 1 P 2 P 3} model M 1 is trained using the parameter set P
2016-1-14 2 Spectra Analysis Figure 6 shows the stator fault spectral signature corresponding to the three considered conditions reported in Table 5 at the rotating speed of 1800 rpm ([f sub l] = 60 Hz) From this figure it can be observed that the frequency component at 120 Hz increases its magnitude with respect to the fault level
Incipient fault diagnosis is very important because if the fault is undetected small motor failure can lead to serious motor failure The objective of this work is the study and the realization of a diagnosis based on signal processing by the Park method of a wound rotor induction machine (in real-time)
