This paper describes a methodology to assist in the identification of possible conceptual design variants during redesign. The approach is based on functional reasoning and involves: (1) the structural and functional analysis of an existing design; (2) the production of abstract representations of functions and design entities using conceptual graphs; and(More)
This work presents a Fault Detection and Diagnosis (FDD) system that uses a combination of discrete wavelet transform and auto-associative neural network. The neural network is trained by Levenberg-Marquardt (LM) algorithm. As a case study, it considers a 5.2MW Siemens Taurus 60S industrial gas turbine. The work is unique in the sense that it addresses the(More)
The present study examines the effects of partial slip bearing configuration on improvement in load capacity and reduction in friction coefficient for journal bearing lubricated with couple stress fluids. The couple stresses effects are analyzed based on Stokes micro-continuum theory and partial slip configuration is analyzed using Navier slip boundary(More)
