In spark ignition (SI) engines, the accurate control of air fuel ratio (AFR) in the stoichiometric value is required to reduce emission and fuel consumption. The wide operating range, the inherent nonlinearities and the modeling uncertainties of the engine system are the main difficulties arising in the design of AFR controller. In this paper, an optimization-based nonlinear control law is a...

This article presents an evolution of the inverse Play model to reconstruct static hysteresis from a flux density waveform input. It is be combined with dynamic and 2-D or 3-D models estimate complete iron loss in electrical machines. In first part article, shows significant improvement original accuracy obtained by modifying characterization measurement methodology, subsequent discretization, ...

Two circuit design techniques improve the robustness of Whitenoise encryption algorithm implementation against side-channel attacks based on dynamic and/or static power consumption. The first technique aims to conceal the power consumption and has linear cost. The second technique aims to randomize the power consumption and has quadratic cost. These techniques are not mutual exclusive; their sy...

a common problem arising in project management is the fact that the baseline schedule is often disrupted during the project execution because of uncertain parameters. as a result, project managers are often unable to meet the deadline time of the milestones. robust project scheduling is an effective approach in case of uncertainty. upon adopting this approach, schedules are protected against po...

In automatic speech recognition mel-frequency cepstral coefficients (MFCC) or linear predictive cepstral coefficients (LPCC) are features commonly used today. However, their calculation considers only a few features of the auditory system. On the assumption that the human representation of speech is an optimal representation, considering more features of the auditory system might lead to a bett...
