Fault Diagnosis of Lubrication System in Internal Combustion Engine
2019 IEEE International Conference on Prognostics and Health Management (ICPHM), 2019Continuous Variable Displacement Oil Pumps (cV-DOP) are increasingly employed in internal combustion engines to reduce parasitic losses, thereby increasing the overall efficiency. These pumps work on the principle of closed loop control to deliver just the right amount of oil flow and pressure that is required to prevent metal to metal contact of ...

Detection of Internal Stuck-open Faults in Scan Chains
2008 IEEE International Test Conference, 2008Nearly half of the transistors in the logic parts of large VLSI designs typically reside inside scan cells. Faults in scan cells may affect functional operation if left undetected. Such undetected faults may also affect the long term reliability of shipped products. Nevertheless, current test generation procedures do not directly target faults internal

Detection of internal faults in transformers using nonlinear observers
Proceedings of 2003 IEEE Conference on Control Applications, 2003. CCA 2003., 2004The developments in transformer construction made the basic principle of the classical differential protection not practicable, when some kind of faults are present in the transformer. Internal faults could not be detected by using differential protection. In this work an approach based on analytical redundancy is applied to the problem of detection of

Residual generation for fault detection of internal combustion engine
Proceedings of the 12th International Conference on Computer Systems and Technologies - CompSysTech '11, 2011Fault detection (FD) scheme is developed for automotive engines in this paper. The method uses an independent Radial Basis Function (RBF) Neural Network model to model engine dynamics, and the modelling errors are used to form the basis for residual generation.

Simulation of transformer internal faults
2020This paper is based on the techniques of modeling and simulating transformer internal faults. The modeling of turn to turn and turn to earth fault is objective of this study. The detailed mathematical formulation of internal faults is developed by using Transmission Line Method (TLM).

A method for the deductive fault simulation of faults in inverter-free circuits is presented. It is shown that in an inverter-free circuit, fault lists on lines with complementary logic values are disjoint, and fault list calculations can be done by performing fewer set operations compared to conventional gate level deductive simulation.

The author develops an approach for prediction of transformation stresses and microstructures of stress-induced internally faulted martensite plates. Only the initial instant of transformation is considered. The additional free energy associated with stacking faults in the martensite is accounted and a simple model relating this energy to the stacking ...
