We have developed calibration and data processing techniques optimized specifically for photon-integrating pixel array detectors (PADs). Primary effects to be calibrated are pixel gain variation and pixel area variation. Gain variations originate in pixel electronics and may be corrected for via a multiplicative factor. In contrast, area variations result from doping inhomogeneities in the sens...

The Hybrid Learning Model is an interactional model that encapsulates teaching and learning in a plain English format and captures the processes from the learner and the teacher perspective. The Model and its capabilities in addressing the challenges associated with capturing and describing teaching and learning practice for dissemination and redesign are examined. The effectiveness of this Mod...

This multimedia experience brings forth viewpoints, insights, and practices about who, why, what, and how to create excellence in project management. First, assemble pieces of a puzzle that optimize the environment for project work; second, traverse the path where a project office leads the change process to develop a project-based organization; and third, develop excellence in project sponsors...

These two admirable summaries of the past year's work do much to lighten the labours of the practitioner. They traverse the same ground for the most part, and may be compared side by side. The Year-Book is, as heretofore, occasionally disfigured by the personal opinion of the reporter on the paper which he abstracts; this opinion is always uncalled for, and often impudent. There is nothing of t...

We propose the creation of a multi-domain measurement framework with dynamic characteristics identical to that of the network as a whole. Our approach recognises and facilitates the ability of independent network entities to set policies and limits on the use of measurement resources locally while encouraging and facilitating the use of such resources by users interested in network paths that t...

Disk subsystems span the range of configuration complexity from single disk drives to large installations of disk arrays. They can be directly attached to individual computer systems or configured as larger, shared access Storage Area Networks (SANs). It is a significant task to evaluate the performance of these subsystems especially when considering the range of performance requirements of any...

In wireless sensor networks (WSNs), congestion may bring about degradation of overall channel quality and increased loss rates, leads to buffer drops and enlarged delays, and tends to be disgustingly unfair toward nodes whose data has to traverse a larger number of hops. Provisioning a WSN so that congestion is an infrequent occasion is quite challenging task. This paper presents a performance ...

Scrollbars provide a simple way to traverse an information space, but they provide little data about the actual contents of the space. Of the many visualization techniques that have been proposed, few have maintained the simple functionality of the scrollbar while showing improved performance on typical scrollbar tasks. This paper presents two enhancements to the scrollbar, a mural bar and a pi...

This paper presents the time complexity of two algorithms that update space-filling curves of adaptively refined domains. The Modified Hilbert (space-filling) Curve was proposed to traverse square-shaped adaptive-refined meshes. Whereas, the Sierpiński-like (space-filling) Curve was proposed in order to traverse triangular-shaped adaptive-refined meshes. Those curves are variations of the names...
