The non-linear effects that have been observed in adaptive filtering scenarios arc explained from the point of view of the structure that underlies the desired data. While the model structure used by the conventional adaptive filter is a linear combination of lapped-dclay line signals, that adaptive filter model does not generally correspond to the structure that best describes the desired data...

This paper presents TDL, a typed feature-based representation language and inference system. Type deeni-tions in TDL consist of type and feature constraints over the boolean connectives. TDL supports open-and closed-world reasoning over types and allows for partitions and incompatible types. Working with partially as well as with fully expanded types is possible. EEcient reasoning in TDL is acc...

There is an extensive literature on task modelling related to the design of computer systems. Task analysis and task modelling have been widely recognized as central components in human-centred approaches. The aim of this paper is to report on some results of a worldwide survey about actual practices of task descriptions languages (TDL) in SIGCHI community. Results suggest that academic TDL are...

Well-designed templates of electronic patient record (EPR) are efficient for consistent and standardized records. Template definition language (TDL) 1 , which can represent the content and structure of EPR template, was developed to promote sharing of templates among clinics and institutions. TDL is one of the many applications of XML therefore a TDL document is a human-readable tagged text and...

In order to isolate genes regulating sex differentiation of embryonic gonads, we have attempted to obtain genes specifically expressed in male embryonic gonads by means of subtractive hybridization screening, and we have cloned a novel mouse gene, Tdl. It potentially encodes a protein showing sequence homology to anti-microbial protein, beta-defensins. Tdl reveals structural features such as th...

We present the Timing Definition Language (TDL), which supports the development of dependable embedded real-time systems. TDL is conceptually based on the time-triggered programming model introduced by Giotto but provides a more convenient syntax, more control over the timing of periodic activities, an industrial strength tool chain, and, most importantly, adds a component model and supports th...

The design of optimum systems, in the classical sense, requires a priori some knowledge of the signals to be encountered. As a result, such systems perform poorly when the appropriate characteristics of the input signals are not known a priori sufficiently well or are timevarying. An adaptive processor has the ability to selfoptimize by continually monitoring its performance and updating its pa...

We address three main problems regarding the use of the traditional dataflow language (TDL) for modelling large and dynamic networks: • The problem of scalability. The concepts and notations of TDL do not scale well. Thus TDL specifications may get large (space consuming) and chaotic. • The problem of generality. TDL does not have the expressibility for specifying networks consisting of n (a ge...
