The paper contains a proposal for an energy and time representation. We construct modes that correspond to fuzzy distributions around discrete values of energy or time. The modes form an orthogonal and complete set in the space of square integrable functions. Energy and time are self adjoint in the space spanned by the modes. The widths of the modes are analyzed as well as their energy-time unc...

Software-implemented approaches to fault tolerance are very resilient to change since evolution in hardware technology does not require extensive re-design of specialized hardware. This paper argues the case for implementing fault tolerance in a distributed fashion and reports the approach adopted in the European Delta-4 project. Fault tolerance is achieved by replicating capsules (the run-time...

A computational model of the peripheral auditory system is used to explain the paradoxical observation that discriminating between broadband noise sounds with and without high-frequency spectral notches is more difficult at mid-intensities than at lower or higher intensities [A. Alves-Pinto, E.A. Lopez-Poveda, Detection of high-frequency spectral notches as a function of level, J. Acoust. Soc. ...

This work seeks virtual constraints, or outputs, that are intrinsic to human walking and utilises these outputs to construct controllers which produce human-like bipedal robotic walking. Beginning with experimental human walking data, human outputs are sought, i.e., functions of the kinematics of the human over time, which provides a low-dimensional representation of human walking. It will be s...

Reasoning about temporal information is an important task in many areas of Artiicial Intelligence. In this paper we address the problem of scal-ability in temporal reasoning by providing a collection of new algorithms for eeciently managing large sets of qualitative temporal relations. We focus on the class of relations forming the Point Algebra (PA-relations) and on a major extension to includ...

Stochastic differential equations have a built-in direction of time flow since future increments in the driving process are assumed independent of present and past values of the process defined by the solution of the equation. The differential equations are thought of as evolving forward in time, normally from some fixed initial time, and the integral representation of a solution, involving as ...

This paper presents the recent developments dealing with our metrical score representation format and how it can be used to produce and manipulate musical scores in PWGL. The base of these ideas is a special score format, called ENP-Score-notation, that allows to describe in textual form various score elements like beats, measures, voices and parts. This basic format can be extended using keywo...

Temporal Action Logic is a well established logical formalism for reasoning about action and change using an explicit time representation that makes it suitable for applications that involve complex temporal reasoning. We take advantage of constraint satisfaction technology to facilitate such reasoning through temporal constraint networks. Extensions are introduced that make generation of actio...

Readily available information is a crucial basis for making decisions, solving problems, or performing knowledge intensive work. Providing such information meeting the needs of a user has to be based on an accurate, purpose-oriented and up-to-date representation of the demand in question. The paper is devoted to a study of different context-based models of user demand. The selected approaches f...

Temporal metadata are significant for the management of cultural collections since every object has a historical reference. The goal of this paper is to enrich collectionlevel descriptions with time representation and management capabilities. We obtain this by deploying a formalism called Multidimensional RDF, which enables the RDF model to represent in a compact way multiple facets of informat...
