The absorption spectra for CO Laser radiation in the 3v3 overtone bands of ²³⁸UF6 and ²³⁵UF6 have been measured using photoacoustic spectroscopic technology. The determined experimentally absorption coefficients and cross-section of the 3v3...

The design of a RSNOM developed in our laboratory is described in detail. Two methods used for making the fiber tip: the heating and pulling method and the etching method, are evaluated and compared. The differences between RSNOM and SNOM in transmission mode are also analyzed. The RSNOM was also us...

How to quickly compute the number of points on an Elliptic Curve (EC) has been a longstanding challenge. The computational complexity of the algorithm usually employed makes it highly inefficient. Unlike the general EC, a simple method called the Weil theorem can be used to compute the order of an E...

The metal powder direct and rapid prototyping technology is one of the most developing methods in the laser rapid prototyping technique. The coaxial powder delivery system is the key technique. The purpose of this paper is to introduce a new type of coaxial powder delivery system and simulate the me...

Recent experimental results of the Doppler effect formula verification are reported. The moving emitters are hydrogen atoms in the excited state. The results of the work corroborate the classical, not the relativistic, formula for the Doppler effect.
