Design and validation of a novel dosimetry phantom for motion management audits
Journal of Applied Clinical Medical Physics, EarlyView.Abstract Background We present a novel phantom design for conducting end‐to‐end dosimetry audits for respiratory motion management of two anatomical treatment sites. The design enables radiochromic film measurements of the dose administered to the target throughout the respiratory cycle (motion‐included) and the dose delivered to the time‐averaged ...

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.

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. A corresponding difference

Proceedings of the 17th international conference on World Wide Web, 2008
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.

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 ...

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 ...

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.
