This article discusses two Lyapunov based robust target following techniques and introduces a method based on the superposition of elementary vehicle dynamics. All three approaches are discussed and physically tested together with a known Lyapunov method for closed loop control. Emphasis is given on the discussion of distinguishing features and parameters relevant for practical selection of tar...

In this paper a model of a multimedia source is proposed in order to evaluate performance in an ATM multiplexer loaded by multimedia traffic. A multimedia arrival process is defined as the superposition of heterogeneous correlated arrival processes. To this purpose each monomedia source is modeled by an Interrupted Bernoulli Process (IBP) and the correlation among the media belonging to the sam...

This paper gave a method in tackling the animation of leaves’ movement. Various kinds of leaves were classified into two classes: moveable and non-moveable. For moveable leaves, their movements are consisted of two parts: leafstalk’s rotation and leaf surface’s rotation. For each rotation, a movement model was constructed and the movement was computed based on each model, respectively. The fina...

For a given σ-ideal of sets, the notion of a generalized stepfunction is introduced and investigated in connection with the problem of sup-measurability of certain functions of two variables, regarded as superposition operators. 2000 Mathematics Subject Classification: 28A05, 28D05.

We present a Virtual Interface to Feel Emotions called VIFE _alpha v.01 (Virtual Interface to Feel Emotions). The work investigates the idea of Synaesthesia and her enormous possibilities creating new realities, sensations and zones where the user can find new points of interaction. This interface allows the user to create sonorous and visual compositions in real time. 6 three-dimensional sonor...

We present a model of coordination within Interaction Grammars. The notion of polarity lets us define the interface of a syntactic structure as its capacity to combine with other syntactic structures in terms of requirements and resources. The coordination of two conjuncts is then viewed as the superposition of their syntactic structure interfaces. Those structures are represented by means of t...

We propose a method for obtaining clear underwater images by tracking the motion of suspended matter from video images captured in water and by separating the images into foreground and background. We assume that input images are the superposition of a foreground and a background, and constructed a transition model and the observation model. An input image is divided into patches and tracking o...

Attention is focused on continuous-space shift-invariant systems with continuous system maps and inputs and outputs that are elements of L∞(IR ). It is shown that infinite superposition can fail in this important setting. It is also shown that continuous shift-invariant linear mappings need not commute with the operation of integration (even when the two composite operations are well defined). ...

The proposed new spectral reflection model enhances the classical Clapper-Yule model by taking into account the fact that proportionally more incident light through a given colorant surface is reflected back onto the same colorant surface than onto other colorant surfaces. It comprises a weighted mean between a component specifying the part of the incident light that exits through the same colo...

The multiple access channel with private messages has a single accepted capacity characterization. By contrast, when the same channel is considered with message sources that may be commonly known to multiple transmitters, a plurality of distinct capacity descriptions arises. Two descriptions currently exist in the literature, with the capacity region attained with superposition coding in one de...
