A SCHEME FOR GAIN FLATTEN OF FIBRE RAMAN AMPLIFIER FOR WDM TRANSMISSION SYSTEMS
(R&D Wing, MIST, 2010-02) Hossain, Md. Azmal; Ahmed, Feroz; Rahman, Mohammad Shamsur
The most attractive feature of Fiber Raman amplifiers are extremely large gain bandwidth and play an important role in wavelength division multiplexing (WDM) systems. However, the weakness of Raman amplifier is that the gain spectrum is flat for very small narrowband. So, it is necessary to flatten the Raman gain profile to achieve the desire performance for the WDM systems. This paper has proposed an extrinsic gain flattening technique for WDM transmission systems using Polarization-diversity Loop Filter (PDLF). With this technique, an equalize bandwidth of 114nm (1536nm – 1650nm) can be achieved with a gain ripple of 0.5dB.
COUNTRYWIDE INTERNET CONNECTIVITY USING WIMAX DEPLOYMENT CAN BOOST RURAL DEVELOPMENT OF BANGLADESH

Being a popular mechanism for access based networks; wireless access medium has found its growth potentials unmatched against wired medium in areas which require rapid rollout and has constraints to infrastructure. Right now Bangladesh is experiencing a boom in Internet usage starting from 2002 when prices of access devices started to be slashed, providing options to home users to dream on wireless connectivity. After the establishment of the NFAP, it is possible to create a structured wireless access network throughout Bangladesh. A developing country which has limited infrastructure will find it increasingly difficult to compare WiMAX with access network technologies such as CDMA and GSM. In this article, I have tried to provide information which would make it logical for the development of rural people for a nationwide WiMAX deployment. As networks such as WiMAX require large bandwidth as well as supporting infrastructure, therefore the deployment of fiber optic infrastructure throughout the country would enhance the WiMAX network flourish. Fiber @ Home is the first company which acquires the NTTN (Nationwide Telecommunications Transmission Network) license in Bangladesh, issued by the BTRC is responsible to cover Bangladesh by laying out fiber optic network that will eventually become the major backbone for all kinds of telecommunications and electronic entertainment services, we are enjoying these days. A WiMAX based infrastructure deployment of such a large scale is principally dependent on the frequency allocation for the operator. And the operator will use 2.5GHz or 3.5GHz for the nationwide WiMax deployment.

Good Food - An Online Office Meal Service
(Daffodil International University, 2021) Aktaruzzaman, Md.; Hossain, Md. Azmal
This project is “Good Food - An Online Office Meal Service”. The purpose of our project is to develop an online application where the Office can order food for their staff. This system Serve combo type of meal and food good for more staffs. This will be a different type Customer access system. Every software development follows some rules and method; we are also following some methods to develop this project. Our whole project work will follow the agile methodology. Which is best software development process to develop a software. We choose it because our whole project needs to implement some part then test it and agile methodology will help us to reduce the project risk.
