The World Wide Web Consortium's RDF standard primarily consists of (subject, property, object) triples that specify the value that a given subject has for a given property. However, it is frequently the case that even for a fixed subject and property, the value varies with time.

Perceptual and Motor Skills, 1976
Five future points of time (range: 1977 to 2034), described in terms of either (A) year number, or (B) “after N years,” were scaled using two different types of scaling method. Subjective temporal distance was in each case a power function of chronological time, the exponent being consistently lower in Condition A than in B.

Newsletters on Stratigraphy, 2012
This report summarizes the international divisions and ages in the Geologic Time Scale, published in 2012 (GTS2012). Since 2004, when GTS2004 was detailed, major developments have taken place that directly bear and have considerable impact on the intricate science of geologic time scaling.

IEEE Transactions on Instrumentation and Measurement, 2013
Time measurement is of great importance for science, technology, and commerce. Among the seven base units of the International System of Units, the second can be realized with the smallest uncertainty, currently reaching parts in 1016. Keeping track of the continuous accumulation of seconds allows the formation of time scales that serve as references ...

Proceedings of the International School of Physics “Enrico Fermi”, 2006
The definitions of time scales and the current international reference for timekeeping are described pointing out the main strengths of the system. The main application of timekeeping and time metrology, the Global Satellite Navigation Systems, are also introduced.

Metrologia, 1971
Techniques of construction of atomic time scales are discussed and experiments at the National Research Council using a group of commercial cesium standards and the NRC 2.1 m laboratory cesium standard, Cs III, are described. Time scales based on the multiple standard approach are compared with the scale UTA (NRC) resulting from the periodic ...

Time-Frequency/Time-Scale Reassignment
2003This chapter reviews the reassignment principle, which aims at “sharpening” time-frequency and time-scale representations in order to improve their readability.

Subsystems, Time Scales and Multimodeling
IFAC Proceedings Volumes, 1980Abstract Through a couple of naive examples the control theorists are invited to reexamine the role of modeling in the study of large scale dynamic systems. Instead of assuming the existence of “N diagonally dominant blocks, ”they should identify one strongly coupled slow core and N weakly coupled fast subsystems.This structure is exhibited with a ...

An application of atomic frequency standards is the establishment of atomic time scales. International Atomic Time is the official basis by which events are dated. However, the need to distinguish between theoretical times and their realizations, the need for a relativistic treatment and the survival of previous astronomical times generate a complex ...

Biological Cybernetics, 1988
A conceptually simple and logically consistent version of ``scale-space'' for the temporal domain is proposed. The method does not violate temporal causality, yet conserves causality in the resolution domain at any given moment in time. The filter kernels are not Gaussians (that would certainly lead to a violation of temporal causality) but are related
