No matter how often a user uses Internet, waiting for a web page to load is really an annoyance. To overcome this situation, Internet speed has increased significantly in the past decade to keep pace with the demand of users, new services and bandwidth-hungry applications. These demands include as multimedia content based e-commerce, video on demand, high definition TV, IPTV, online gaming, social media, etc. Lots of different technologies like gigabit Ethernet, mobile Internet, etc. that have been trying to cater and satisfy the user demand. FTTH(Fiber to the home) is one of the high-speed access technology which offers triple play service (i. e., data, voice and video) EPON/GPON is easier, faster and low cost. EPON/ GPON can transport Ethernet, ATM and TDM (PSTN, ISDN, E1 and E3) traffic. It has been widely accepted by Internet service providers and operators in terms of bandwidth upgrade, service bearer as well as passive network maintenance. High bandwidth capacity, high quality and multi-play services through a single channel presents a strong business opportunity for telecom operators as it provides support which includes voice, Ethernet, ATM, leased lines and others. FTTH offers simple operation, administration, maintenance and provisioning capabilities as well as end-toend service management. It not only provides substantially higher efficiency as a transport network, but also delivers simplicity and superb scalability for future expansion in supporting additional services. According to the contents above, we can see that there are own advantages and disadvantages of EPON and GPON. In performance comparison, GPON is better than EPON, while EPON has many advantages on time and cost. And now, EPON is still the mainstream of PON, and meanwhile, GPON is catching up with it. Going forward to the broadband access market, maybe it is not substitution between EPON and GPON. It is more likely that they are coexist to complement each other. For the users who have demands of multi-service, high QoS and security, as well as ATM backbone network, GPON seems to be an ideal.

Turza Ibna Large tracts of land in the delta region of Bangladesh are left fallow or are cultivated with low input crops during the dry winter months. Surface water based irrigation opens up new opportunities for sustainable intensification by enabling the production of a high yielding crop. Irrigation in Bangladesh is still managed in a very traditional manner without considering scientific data on soil and weather which increase cost of farming and also lower productivity. Farmers usually depends on their past experience. In a traditional way, they forecast the weather as well as the moisture of the land. So the process the irrigation depends more on their guess. The simulation model has been integrated into a smart phone app called PANI (Program for Advanced Numerical Irrigation). PANI runs on a daily time step and uses forecasted weather data to predict irrigation needs one week in advance. I used the calibration of the Blainy-Criddle Equation so that only forecasted daily maximum and minimum temperatures are required. PANI addresses the needs of the irrigation service provider as well as of the farmer. Both will receive the field data, informing them as to whether a field needs to be irrigated or not. Since the water balance of PANI is based on the SVM algorithm, it can be used under most conditions, as long as weather and ground cover data are available.

Minhaz Ul In the field of agriculture information, automatic detection and diagnosis of plant disease and pest is highly desirable. Feature extraction technologies play a critical and crucial role in leaf disease detection and diagnostic system. Researches in leaf disease detection have used many different feature detection techniques like color, texture, shape etc. Recently very promising results are found using deep learning in different types of computer vision problems. Now a days deep learning is hot research topic in pattern recognition, machine learning as well as artificial intelligence. Deep neural network-based models can be an effective solution to vegetable pathology. In this research I have proposed a novel rice disease and pest detection model which is based on deep convolutional neural networks (CNN). This model gives a training accuracy of 80.11% with 77.68% training accuracy.
