The classical view of artificial intelligence (AI) is tied down by a number of problems. These problems indicate that it might be fruitful to approach AI applications, including spoken dialogue systems, in an alternative way. This paper overviews current attempts to apply the idea of layered behavior-based architectures in dialogue system development. It is concluded that there are both theoret...

The paper presents a two-layered system for learning and encoding a periodic signal and its application to a drumming task. The two layers are the dynamical system responsible for extracting the main frequency of the input signal, based on adaptive frequency oscillators, and the dynamical system responsible for learning of the waveform with a built in learning algorithm. By combining the two dy...

In rich scattering environments, layered Space Time architectures like the BLAST (Bell Labs Layered Space Time) system may exploit the capacity advantage of multiple antenna systems. In case of a broadband wireless transmission, the channel undergoes frequency selective fading which necessitates the receiver to have a multi tap equalizer. This can be avoided by employing an OFDM (Orthogonal Fre...

In this paper to predict the critical conditions for onset of elastic-plastic wrinkling of flange of a two-layered circular blank during the deep-drawing process a closed-form semi-analytical elastic-plastic solution using Tresca yield criterion alongwith deformation theory in plasticity with considernig the perfectly plastic behaviour of materials is presented. Simplifying the presented soluti...

The aim of this paper is to investigate adhesion property between nano-layered filler and the polymer matrix using a combination of experimental and micromechanical models as well as the changes in yield strength and stiffness of a layered silicate-filled epoxy nanocomposite. The results indicate that addition of intercalated layered silicate particles increased Young’s modulus and yield streng...

The double-layered peer-to-peer (P2P) systems were introduced to reduce the network traffic in MANET. The peers in the systems are classified into super peers and sub-peers. Super peers manage their neighboring sub-peers. The network communications in the systems are done mostly among super peers. In case when a pair of neighboring super peers is too far to communicate, one or two of their sub-...

Because of diversity, complexity and poor information about non-layered orebody, it is difficult to be accurately described by regular geometry model. Mining engineers couldn’t accurately estimate the space distribution law of orebody's grade, quality and the total reserve according to the traditional 2-dementional (2D)graphics. So it is necessary to accurately establish non-layered orebody mod...

high speed trains are an indispensable part of rapid transportation systems in many countries. as the fastest means of transport on the ground, these trains are extremely sensitive to the terrain and track conditions. geometrical irregularities and mechanical characteristics of the track, together with inconsistencies in the lane (including bridges that support the track) are considered importa...

rotavirus, a triple-layered non-enveloped member of the reoviridae family, obtained a transient membrane envelope when newly synthesized subviral particles bud into the endoplasmic reticulum (er). as rotavirus particles mature, they lose their transient membrane and obtain outer layer. it is mostly believed that only double layered particles bud into the er. the present study describes that the...

Data mining is the automatic discovery of patterns, associations, and anomalies in data sets. Data mining requires numerically and statistically intensive queries. Our assumption is that data mining requires a specialized data management infrastructure to support the aforementioned intensive queries, but because of the sizes of the data involved, this infrastructure is layered over a hierarchic...
