Terahertz (THz) research has received much attention recently. This development is due to the discovery of new THz-radiation sources and detectors such as quantum cascade lasers, photoconductive switches or electro-optic THz- detectors during the last decade. Of particular intereset are broadband Thz-spectroscopy and imaging systems operating in the frequency range 0.1-10THz. This paper describes a technique for imaging in the terahertz regime using time reversal of single cycle pulses. Specifically, the time-reversal symmetry of Maxwell?s wave ....etc

Abstract:
Dental Composites to Degraded MLI:


Ben Reed's experience as a materials engineer has led him from the challenges of dental composites to long term space exposure on the Hubble Space Telescope (HST).

Dental composites were developed in the 1960s and have continued to play a major role in restorative dentistry to date. However, they do not exhibit the typical service life of silver amalgam or gold fillings. Much of their lower service life is due to the consequences of polymerization shrinkage.

The Hu ....etc

INTRODUCTION OF PROJECT



The basic objective of this project regarding “COMPUTERIZATION OF A DENTAL CLINIC” is to eliminate the use of conventional methods of storing records (Viz. on papers, files) which are obviously time consuming, cumbersome and also require more storage.
Thus, computerization should allow quick storage of records and quicker completion of other formalities as well.
It would also lead to easier access the records and ....etc

Dental Biometrics:
this seminar describes foundations of a biometric system for semi-automatic processing and matching of dental images, with the final goal of human identification. Given a dental record, usually as a postmortem (PM) radiograph, And need to search the database of antemortem (AM) radiographs to determine the identity of the person associated with the PM image.use a semi-automatic method to extract shapes of the teeth from the AM and PM radiographs, and find the affine transform that best fits the shapes in the PM image to thos ....etc

INTRODUCTION

Teeth (singular tooth) are small, calcified, whitish structures found in the jaws (or mouths) of many vertebrates that are used to tear, scrape, and chew food. Some animals, particularly carnivores, also use teeth for hunting or defense. The roots of teeth are covered by gums. Teeth are not made of bone, but rather of tissues of varying density and hardness ....etc
