As mobile devices become more and more complex, there is an increasing desire for these devices to adapt to their users. This paper identifies parameters for different input sources (user, device and environment), and the parameters of media output (speech, graphics , sound and text), that may be modified to tailor user presentation in a pedestrian navigation system. We also provide an initial ...

his article deals with the identification of nonlinear models T in observer canonical form of hydraulic servo-drives from sampled data of input-output measurements. The data are processed by a modified Recursive Instrumental Variables algorithm, to provide input-output relationships of the plant dynamics. From the parameters of the input-output relations, continuous state-space nonlinear models...

A new adaptive step size adjustment least mean square (LMS) algorithm is presented in this paper. The proposed algorithm modified the existing LMS using the estimated output error as an important component for the modification of the step size. Experiment results demonstrate that application of the new algorithm leads to a significant gain in SNR (signal-to-noise ratio), thus visibly reduces th...

We generalize the formulation of associative reservoir computing networks to multiple input modalities and demonstrate applications in image and audio processing scenarios. Robust association with reservoir networks requires to cope with potential error amplification of output feedback dynamics and to handle differently sized input and output modalities. We propose a dendritic neuron model in c...

We consider nonlinear systems in an output feedback form which are functionally known up to a L2 measure of uncertainty. The control task is to drive the output of the system to some neighbourhood of the origin. A modified L2 measure of transient performance (penalis­ ing both state and control effort) is given, and the per­ formance of a class of model based adaptive controllers is studied. An...

Microstructured optical fibers containing alkali halide scintillation materials of CsI(Na), CsI(Tl), and NaI(Tl) are presented. The scintillation materials are grown inside the microstructured fibers using a modified BridgmanStockbarger technique. The x-ray photon counts of these fibers, with and without an aluminum film coating are compared to the output of a collimated CdTe solid state detect...

The 1-D Teager algorithm can be used to perform mean weighted highpass filtering with relatively few operations. We propose a generalization of the Teager algorithm. The modified algorithm allows us to adjust the dependence of the highpass output on the local mean. The derivation and interpretation of the modified algorithm is presented. Finally, the response of several implementations to a tes...

In this paper comparative study of proposed hybrid multilevel inverter (HMI) operating in modified pulse width modulation (PWM) mode with cascaded H-bridge multilevel inverter (CHMI) is done. Two types of HMIs are proposed with same configuration. To control the two HMIs, modified PWM techniques are derived from sinusoidal pulse width modulation (SPWM) to reduce the switching losses in the inve...

In most countries, systems are in place to analyse food products for the potential presence of genetically modified organisms (GMOs), to enforce labelling requirements and to screen for the potential presence of unauthorised GMOs. With the growing number of GMOs on the world market, a larger diversity of methods is required for informative analyses. In this paper, the specificity of an extended...
