Optimization of Functionally Graded Beams Resting on Elastic Foundations
In this study, two goals are followed. First, by means of the Generalized Differential Quadrature (GDQ) method, parametric analysis on the vibration characteristics of three-parameter Functionally Graded (FG) beams on variable elastic foundations is studied. These parameters include (a) three parameters of power-law distribution, (b) variable Winkler foundation modulus, (c) two-parameter elasti...
متن کاملNondestructive Evaluation of Damage in Beams Using Displacement Curvature
In this paper, the capabilities of displacement curvature derived from static response data for finding the location and severity of damage in Euler-Bernoulli beams are assessed. Static response of a beam is obtained using the finite element modeling. In order to reduce the number of measured nodal displacements, the beam deflection is fitted through a polynomial function using a limited number...
متن کاملFinancial predictions based on bootstrap-neural networks
In this paper neural netw orks are applied to nancial data in order to predict the daily price of the nancial index LIFFE. Our atten tion is focused on the choice of the exogeneous variables and on the training of the netw ork itself. The rst problem is solved by using the pre-whitening method that provides information on which variables are the most relevan t for our prediction. The latter pro...
متن کاملMulti-task Neural Networks for QSAR Predictions
Although artificial neural networks have occasionally been used for Quantitative Structure-Activity/Property Relationship (QSAR/QSPR)studies in the past, the literature has of late been dominated by other machine learning techniques such as random forests. However, a variety of new neural net techniques along with successful applications in other domains have renewed interest in network approac...
متن کاملActive Steering Control for Railway Bogies Based on Displacement Measurments
This paper presents an active steering control strategy that improves the performance of rail vehicles on track curves. The control scheme is developed to explore the usually symmetrical arrangement of bogie suspensions such that only simple and practical sensors are needed. The vehicle configuration and requirements of wheelset steering on curves are explained, before the detailed control desi...
