Coherence in text and hypertext


Abstract:

The concept of text coherence was developed for linear text, i.e. text of sequentially
organized content. The present article addresses to what extent this concept
can be applied to hypertext. Following the introduction (section 1), I will define
different aspects of text coherence (section 2). I will then explain the importance
of the sequential order of text constituents for coherence-building, as explored by
empirical studies on text comprehens ....etc

Optical Coherence Tomography (OCT)

Introduction
Optical Coherence Tomography (OCT) is an imaging technique that is similar in principle to ultrasound, but with superior resolution. It relies on exposing a sample to a burst of light and then measuring the reflective response from different depths and is therefore capable of scanning non-invasively beneath the surface of the sample. In ultrasound imaging, it is relatively easy to measure the time delay of each reflected packet. However, for light pulses, interferometry must be used to measure ....etc

Performance analysis of channel estimation and adaptive equalization in slow fading channelPresented By:
Zhifeng Chen, Electrical and Computer Engineering, University of Florida
ABSTRACT
In our project, we first build up a wireless communication simulator including Gray coding, modulation, different channel models (AWGN, flat fading and frequency selective fading channels), channel estimation, adaptive equalization, and demodulation. Next, we test the ef ....etc

In an effort to provide more detailed information about epileptic lesions in neural tissuefor the purpose of efficient removal, an Optical Coherence Tomography system was built to provide non-destructive imaging. The device is based upon the principle of a low-coherenceinterferometer. Such an instrument can detect if a particular point within a sample of tissue reflects light; an integration and interpretation of many scans of many points provides a highresolution image. The device built for this investigation has been successful in scanning se ....etc

RADAR AND SYNTHETIC APERTURE RADAR BASICS
PRINCIPLES OF RADAR
HOW DOES RADAR WORK?
• RADAR = Radio Detection And Ranging
• Since radar pulses propagate at the speed of light, the difference to the “target” is proportional to the time it takes between the transmit event and reception of the radar echo

ABSTRACT :

Orthogonal frequency-division multiplexing is a popular method for high-data-rate wireless transmission. OFDM may be combined with multiple antennas at both the access point and mobile terminal to increase diversity gain and/or enhance system capacity on a time-varying multipath fading channel, resulting in a multiple-inp ....etc

The history of computer technology has involved a sequence of changes ~ZT\ one type of physical realization to another from gears to relays to valves to ~3nsistors to integrated circuits and so on. Today's advanced lithographic *r-:hniques can squeeze fraction of micron wide logic gates and wires onto the s^face of silicon chips. Soon they will yield even smaller parts and inevitably ¦each a point where logic gates are so small that they are made out of only a -^ndful of atoms; i.e. the size of the lo ....etc
