Using Spice to Simulate Gain Dynamics in Doped-fiber Amplifier Chains

Authors: Alberto Bononi, Lorenzo Barbieri, Leslie Ann Rusch
Comments: 2 Pages. This abstract was made public at the optical fiber conference 1998, workshop 204, monday Feb 23, 1998, but not included in the proceedings.

It has recently been shown that gain dynamics in doped-fiber amplifiers can be simulated by an equivalent electric circuit [1]. Here we include ASE-induced self- saturation in the model, and discuss its implementation using SPICE.

On Standardrization of Addresses

Authors: Arjun Dahal
Comments: 3 Pages.

On progressing world, where pigeons are no longer used to carry messages like as in fairy tales, and historical tales, need of standarization of address was felt, for physical and internet means. In this paper, author has attempted to describe address in standard form, allowing to be cited, as per available databases, uniqueness, and accuracy.

Comments: 19 Pages.

Today, the security problem is emerging as a crucial problem for people, and research into solving this problem is now on its way worldwide. Everyone is aware of the urgency and seriousness of the security problem, and at this time, this problem has a giant impact on the overall social life. As science and technology develop, researches for solving security problems are advancing to a new stage, and their reliability is increasing day by day.In this study, a powerful quadruple security system was designed and realized by combining Keypad, RFID, Fingerprint, and Bluetooth (HC06) modules to thoroughly secure the security of medicines, jewelry, documents, and other valuables and doors.This system is based on the Arduino Mega 2560 microcontroller and is an intelligent system with a display function, voice function, SMS transmission function by GSM module, and alarm function. The system is an excellent system that can thoroughly guarantee the safety of security with low cost and low power consumption.
