A simple modification of Horn's circle drawing procedure yields a disk generator for a class of graphic devices capable of drawing rectangular areas. Another variation produces a disk a scan-line at a time allowing it to be drawn at the refresh rate of the display. The calculations involve only additions and binary shifts.

There has been increasing interest inflexible displays and electronics. Flexibility is desirable because it promises low cost manufacture and offers new and emerging applications. A number of competing flexible display technologies are being developed including Electrophoretic, Organic Light Emitting Diode (OLED), and flexible LCDs. Plasma displays have also entered the flexible display arena. ...

The information technology is evolved to accomodate the ever changing end users request for new services. As the request for the high data rate multimedia contents explosively increases the related hardware, software and networking technologies are finding ways to effectively satisfy end users expectation. Aligned with this trend the display device becomes thinner to reduce the weight while sup...

This study presents the fabrication process and display characteristics of a flexible organic polymer display device that consists of a thin substrate of Polyether Sulfone, a multilayer serpentine-type microheater array that is fabricated on the substrate, and a UV-sensitive polydiacetylene (PDA)-polyvinyl alcohol (PVA) composite film. A retention time of one second is achieved with cell sizes ...

objectives the main objective of this study was to design and construct an optical device to determine the rbv in patients undergoing hemodialysis, during the process. materials and methods after initial studies in order to select a proper sensor, using the orcad software, an analog circuit was designed. the implementation and modification of the circuit was done by the clinical tests, using ex...

recent experiments on the spherical tokamak have discovered the conditions to create a powerful plasma and ensure easy shaping and amplification of stability, high bootstrap current and confinement energy. the spherical tours (st) fusion energy development path is complementary to the tokamak burning plasma experiment such as nstx and higher toroidal beta regimes and improves the design of a po...

Mobile messaging is evolving beyond SMS text messaging with the introduction of MMS (Multimedia Messaging Service). In the past, such a scheme is used to peer-to-peer communication. Messages are generally displayed on handset with a limited-sized screen. However, such a visualizing process is not suitable to broadcast real-time SMS/MMS messages to a crowd of people in public. To facilitate the ...
