In this paper, polynomial prediction of Rayleigh fading power signal produced by noise shaping is investigated. We focus on the processing of the measured input signal for power control purposes of a Code Division Multiple Access (CDMA) mobile station receiver. Predictive filtering based on a polynomial signal model is proposed, and a class of FIR-type polynomial predictors is investigated with...

Power analysis attacks against embedded secret key cryptosystems are widely studied since the seminal paper of Paul C. Kocher, Joshua Jaffe and Benjamin Jun in 1998 where has been introduced the powerful Differential Power Analysis. The strength of DPA is such that it became necessary to develop sound and efficient countermeasures. Nowadays embedded cryptographic primitives usually integrate on...

We describe the Optical Pulse Generation (OPG) testbed, which is the integration of the MOR and Preamplifier Development Laboratories. We use this OPG testbed to develop and demonstrate the overall capabilites of the NIF laser system front end. We will present the measured energy and power output, temporal and spatial pulse shaping capability, FM bandwidth and dispersion for beam smoothing, and...

Raw data collected by analytical detectors rarely correlates directly to the data points that are analyzed by the chromatographic software. Rather the data has already been manipulated in some way within the detector, typically post data collection. The most common examples are filtering and smoothing algorithms. The power transformation is simply another internal data manipulation aimed at imp...

This paper analyzes the electromechanical interaction in a flywheel system with a doubly fed induction machine, used for wind farm power smoothing or grid frequency response control. The grid-connected electrical machine is subject to power control, and this can cause it to produce negative damping to the shaft torsional vibration. Resonance must be prevented, and this paper proposes a solution...

Increased electric energy consumption in recent years, associated economic problems, reduced reliability and increased power losses in electric networks. One of the main solutions in smart grids to overcome the mentioned problems is demand response programs. In demand response programs, operators apply time-varying tariffs to consumers, and convince them to change their consumption pattern. Amo...

We study the topology of the Virgo N-body simulations and compare it to the 1.2-Jy redshift survey of IRAS galaxies by means of the genus statistic. Four highresolution simulations of variants of the CDM cosmology are considered: a flat standard model (SCDM), a variant of it with more large-scale power ( τCDM), and two low density universes, one open (OCDM, Ω0 = 0.3) and one flat (ΛCDM, Ω0 = 0....

Voxel-based morphometry (VBM) has detected differences between brains of groups of patients with epilepsy and controls, but the sensitivity for detecting subtle pathological changes in single subjects has not been established. The aim of the study was to test the sensitivity of VBM using statistical parametric mapping (SPM5) to detect hippocampal sclerosis (HS) and cortical neuronal loss in ind...
