In this paper, a dual-wavelength synchronously pulsed fiber laser Q-switched by carbon nanotube-based saturable absorber with switchable wavelength spacing enabled using arrayed waveguide grating (AWG) is proposed and demonstrated. By just switching the channels of the AWG, discrete tuning in wavelength spacing of the dual-wavelength Q-switched las

A passively bidirectional mode-locked fibre laser is demonstrated using a highly concentrated erbium-doped fibre (EDF) as a gain medium. To accomplish mode-locked operation in a short cavity, use is made of carbon nanotubes (CNTs) as a saturable absorber. Soliton pulses are obtained at a wavelength of 1560 nm with a repetition rate ranging from 43.

Online management system is very important nowadays in education (Hamad et al., 2011), recently many systems have been designed in this field to help the users to communicate online (Maimona et al, 2011; Akram et al., 2011; Akram et al., 2012). The Conference Management Online System is the system that will be used by Event Manager in order to mana

Aggregating interesting spatio-temporal events of daily life in a diary used to be favorite pastime for many individuals. However, crescive use of social media through portable digital devices is replacing traditional diary writing. Thanks to ubiquity of smartphones, people can now add multiple media types in order to record joyful moments and even

This study empirically examines the perceptions of bank customers in Côte d’Ivoire on the viability of Islamic banking in the country. Specifically, the study investigates the level of awareness of the bank customer respondents about Islamic banking as well as the factors that motivate their patronage. A sample of 274 respondents residing in Abi

Crimes pose a threat to any society. Considering its implication for the socio-economic activities and development of any country, the cost of crime is therefore burdensome not only to the government but also to the citizen. Controlling criminal activities is therefore imperative to prevent the many resulting negative consequences. Effective contro

There is an increasing interest in tribology community for developing high performance composite coating to meet severe tribological conditions of advanced mechanical system which requires high operating temperature and long life. In the present work, powder preplacement and tungsten inert gas (TIG) torch melting techniques have been employed to ge

The alarming rate of aviation offences such as the offence of aircraft hijacking in the 21st century warrants the need to adopt various preventive and suppressive measures to prevent these offences. The current method to prevent and suppress these offences is to subject every passenger to screening of their body and baggage through the imaging tech

Introduction: Disasters kill thousands of people and damage huge numbers of habitat and properties each year, which gives a big impact to the community involved. Therefore, the fundamental of disaster management is important for emergency nurses as frontline, where its understanding will reduce the impact of disaster and its aftermath. Objective: T

In recent years, the growth in the use of recombinant proteins has grown tremendously. With the aid of the advances in DNA recombinant biotechnology, molecular farming in plants has been applied to meet this increasing demand where plants have emerged as one of the most promising general production platforms for recombinant proteins.
