One major point in loop restructuring for data locality optimization is the choice and the evaluation of data locality criteria. In this paper we show how to compute approximations of window sets deened by Gannon, Jalby, and Gallivan. The window associated with an iteration i describes the \active" portion of an array: elements that have already been referenced before iteration i and that will ...

Management information generated by workflow information systems is often used for planning, costing, decision making and other management activities. By application of the principles of Grounded Theory, this paper summarises studies of acceptance of workflow systems and finds that user resistance is manifest in many forms. The paper also finds that previous divisions of this resistance are sim...

BACKGROUND The use of recombinant tissue plasminogen activator (rtPA) within 3 hours after onset of an ischemic stroke is an established therapy. Because the use of intravenous rtPA beyond a time window of 3 hours after stroke onset is still a matter of debate, we sought to review the evidence for the use of thrombolytic therapy in a time window up to 6 hours after onset of symptoms of ischemic...

Good daylighting design in buildings not only provides a comfortable luminous environment, but also delivers energy savings and comfortable and healthy environments for building occupants. The importance of using daylight in educational buildings is because of the synchrony of operating hours of the school and daylight plenitude the sky. Daylight improves environmental quality and saves energy ...

  Introduction: Poor sensitivity and poor signal to noise ratio because of low injected thallium dose and presence of scattered photons are the main problems in using thallium in scintigraphic imaging of the heart. Scattered photons are the main cause of degrading the contrast and resolution in SPECT imaging that result in error in quantification. Thallium decay is ve...

The Remote Framebuffer protocol, RFB, is a protocol that works at the framebuffer level and used for remote access to graphical user interfaces in order to view and control a remote window system. RFB is applicable to all windowing systems (X11, Windows, Mac), and used in Virtual Network Computing (VNC). This paper provides an analysis for the RFB protocol, including service, components, securi...

Discrete frequency transforms provide a method to obtain a global view of data within a window. Discrete cosine transform is the frequency transform for practical image processing because of its excellent energy compaction property. Another reason for its popularity is the existence of a fast implementation for the algorithm. In this article, the basics of the discrete cosine transform, its use...
