Use of center of gravity with the common vector approach in isolated word recognition
(Pergamon-Elsevier Science LTD, 2011)In this paper, the subspace based classifier, common vector approach (CVA), with the center of gravity (COG) method is used for isolated word recognition. Since the CVA classifier is sensitive to shifts through the time ... -
A new implementation of common matrix approach using third-order tensors for face recognition
(Pergamon-Elsevier Science LTD, 2011)In the classical common matrix approach (CMA), the common matrix for each individual face class is obtained using basis matrices calculated by Gram-Schmidt orthogonalization of the class covariance matrix. This common ... -
A novel modeling approach for hourly forecasting of long-term electric energy demand
(Pergamon-Elsevier Science LTD, 2011)In this study, a novel mathematical method is proposed for modeling and forecasting electric energy demand. The method is capable of making long-term forecasts. However, unlike other long-term forecasting models, the ... -
Influence of Tire Damping on Actively Controlled Quarter-Car Suspensions
(Asme, 2011)In this note, a comprehensive analysis of tire damping effect on H-2-optimal, multi-objective, and robust control of quarter-car suspensions excited by random road disturbances is provided. First, H-2-optimal and convex ... -
Frequency domain subspace-based identification of discrete-time power spectra from uniformly spaced measurements
(Pergamon-Elsevier Science LTD, 2011)In this paper, we revisit the problem of identifying multi-input/multi-output linear-time-invariant discrete-time systems from measured power spectrum data on uniform grids of frequencies studied by Van Overschee, De Moor, ... -
Classifier-based offline feature selection and evaluation for visual tracking of sea-surface and aerial targets
(Spie-Soc Photo-Optical Instrumentation Engineers, 2011)An offline feature selection and evaluation mechanism is used in order to develop a robust visual tracking scheme for sea-surface and aerial targets. The covariance descriptors, known to constitute an efficient signature ... -
Condition monitoring of speed controlled induction motors using wavelet packets and discriminant analysis
(Pergamon-Elsevier Science LTD, 2011)This work presents an intelligent method for the condition monitoring of induction motors supplied with adjustable speed drives (ASD). Most of the previous work in this area concentrated on the fault detection and ... -
A new solution to one sample problem in face recognition using FLDA
(Elsevier Science Inc, 2011)Fisher linear discriminant analysis (FLDA) is a very popular method in face recognition. But FLDA fails when one image per person is available. This is due to the fact that the within-class scatter matrices cannot be ... -
An application for the control of stochastic petri nets via fluidification approach
(2012)Petri nets are frequently used for modeling and analysis of discrete event systems. Similar to other modeling formalisms for discrete systems, it suffers from state explosion. Fluidification can be used to overcome this ... -
Content-Based Microscopic Image Retrieval System for Multi-Image Queries
(IEEE-Inst Electrical Electronics Engineers Inc, 2012)In this paper, we describe the design and development of a multitiered content-based image retrieval (CBIR) system for microscopic images utilizing a reference database that contains images of more than one disease. The ... -
Supervisory controller design to enforce some basic properties in timed-transition Petri nets using stretching
(Elsevier Sci LTD, 2012)Supervisory controller design to enforce boundedness, reversibility, and liveness in timed-transition Petri nets with firing durations is considered. It is assumed that both controllable and uncontrollable transitions may ... -
Stable H-infinity flow controller design using approximation of FIR filters
(SAGE Publications LTD, 2012)Stable flow controllers are usually preferred since, compared with unstable flow controllers, they are less sensitive to any modelling imperfections. H-infinity-optimal flow controllers involve finite impulse-response (FIR) ... -
