Microbend optical fiber sensor for high-spatial resolution measurement of strain distribution
Abstract:
A new optical fiber sensor system has been developed for measuring strain distribution. Microbend scattering process is used for the sensing of strain and high spatial resolution of 1m was achieved for both plastic and silica glass fiber. Keywords: Optical fiber sensor, strain distribution, microbending, plastic fiber, silica fiber, geo-textile,

ARE NATURAL FIBER COMPOSITES ENVIRONMENTALLY SUPERIOR TO GLASS FIBER REINFORCED COMPOSITES?
INTRODUCTION:-
• Natural fibers have been used to reinforce materials for
over 3,000 years.
• Many types of natural fibers have been investigated for
use in plastics .including , Flax, hemp, jute, straw,
wood fiber, rice husks,wheat,barley,oats .
• Natural fibers have the advantage that they are
renewable resources and have marketing appeal.
• Natural fibers are increasingly used in automotive a ....etc

which modulation technique is widely used in optical fiber communication?and why?
can we use ofdm signals in optical communication?and how?

sir,
i want all study report related to optical fiber communication .
i will study those material for submitting seminar and also clear my doubt about modulation techniques in optical communication.
this field/topic is my area of interest,and i really want to study,try to implement it.
thank you!

A dense gas is defined as any gas whose density is greater than the density of the ambient air through which it is being dispersed. This result can be due to a gas with a molecular weight greater than that of air or a gas with a low temperature due to auto-refrigeration during release, or other processes. The importance of dense gas dispersion has been recognized for some time. Early field experiments (Van Ulden, 1974; Puttock et al., 1982; Koopman et al., 1984) have confirmed that the mechanisms of dense gas dispersion differ markedly from neu ....etc

8) Alpha Partial Dispersion

MAIN PURPOSE:
* Ernest Rutherford was a New Zealand born scientist. In 1909, he did some experiment using gold fails and alpha particles. Alpha particles consist of two protons and neutrons bonded to each other, since they have no electrons, they are positively charged with two charge units. View the configuration of the experiment and understand the Rutherford experiment.
* There is a source of fast moving alpha particles that have a considerable amount of energy. The alpha particle streak is dire ....etc
