A Deep Learning Approach to Recognize Bangladeshi Shrimp Species
(Daffodil International University, 23-01-29) Nishi, Jubiria Subrin; Hossain, Md. Rajib
The nutritional value of shrimp, the most consumed shellfish in Bangladesh, is high because of its abundance of various nutrients. Protein, minerals, vitamin D, and iodine are all examples of such things. The name of this seafood means "white gold" in its native Bangladeshi language. More than 70% of the world's agricultural food supply comes from this. Roughly 56 distinct species of shrimp can be found in American waters. Unfortunately, most people only have a cursory understanding of the wide variety of life on our planet. Experienced fishermen sometimes make the mistake of confusing one species with another because of their superficial resemblance. We developed an AI system to aid in shrimp identification to solve the difficulty presented by this paper. We anticipate that this study will also help the export sector in distinguishing between the numerous shrimp species under observation. To accomplish our goals, we developed an in-house convolutional neural network (CNN) algorithm for extracting features and processing images. Here, we construct three unique CNN architectures, each with its own unique hyperparameters and convolutional layers. Model 3 was chosen as the final model for computer vision integration, despite the fact that both Model 1 and Model 3 attained an accuracy of 99.01%. Models 1 and 3 produce the same answer; if model 3 is more accurate, why would we pick it as the final model? Furthermore, we will offer a rational justification for this study's findings.

I have done Internship under Dhaka Metro Rail Project a Larsen & Toubro (L&T) and Italian Thai Development (ITD) - SINOHYDRO JV Sub-contact of ATS Power Limited. I have set up Dhaka metro rail project a sub-station. I have learned well all the work done in this sub-station. Here are the things I saw and learned, A Sub-station is a part of the Electrical Generation, Transmission and Distribution system. Sub-stations convert voltage from high to low or vice versa or conduct in several other important work. We have bus-bar connections on the primary and secondary side. Each gadget gains freely and processing transformer, circuit related power framework information breakers, disconnection, tap changers, CT & PT, SF6 circuit breakers, isolator, conductor, insulator, lightning arrester, really, and switchgear panels installation, Dry type transformer installation, and Earthing work and Underground cable laying and cable tray more. Dhaka Mass Rapid Transit Development Project MRT LINE -6 has been given to control and manage all the works of Dhaka Metro Rail. Supervising all work and testing everything do this MRT LINE -6.
Estimating Traffic Volume To Identify the Level of Service in Major Intersections of Mirpur 10, Dhaka-1216, Bangladesh

The increment of vehicles due to the proportional increment of populations and a rapid development of modern society is a major concern in Metropolitan cities in developing countries like Bangladesh. So, it is imperative to monitor traffic volume as well as the quality of transport supply termed as the Level of Service (LOS). The present study is an investigation of the behavior of mixed traffic flow in Dhaka Mirpur-10 city of Bangladesh. Field Traffic volume survey was carried out to determine the level of service at 3 major Unfinalized intersections in Dhaka north city corporation (DNCC). Level of service (LOS) was determined by volume capacity ratio and peak hour factor (PHF) method. Nature of traffic flow in Dhaka Mirpur-10 city is heterogeneous. So, this heterogeneous or mixed traffic are simplified by Passenger car unit (PCU). Then estimated PCU was used to determine LOS. LOS was calculated for both directions of roads. Car, CNG, Private Car, rickshaw and bike are the dominant vehicles in Manicotti, Mirpur-10. According to PHF method and V/C ratio method, LOS of Manicotti intersection is very unstable and worst. Residential area is very worst in nature after analyzing both V/C ratio and PHF method. Considering and evaluating all the findings it can be recommended that Restriction for truck movement in daytime should be applied in Manicotti intersection and width. Also, incorporation of an effective traffic signal, traffic rules and regulation should be applied and maintained properly in the worst condition intersection should be extra bike lane rout system the traffic flow in Mirpur-10 DNCC area.
Investigation of Silicon Wash, Enzyme Wash & Acid Wash Effects on Knit Garments
(Daffodil International University, 2019-04-25) Antor, Md.Sofiul Alom; Siddique, Abu Bakar; Hossain, Md. Rajib
This Paper deals with 3 types of washing .These are Silicon, Enzyme and Acid washing. Those 3 types of washing is applied on 100% S/J fabric, Terry fabric and Rib Fabric. Typical Washing process is followed in this task. We measure the GSM of after wash and before wash value of these three type of fabric, also measure Shrinkage, EPI, PPI, Pilling, Abrasion of those fabric. We used 3 type of machine to complete this work. We got significant change of properties between after and before wash. Specially the value of GSM varies lots. The value of shrinkage is decrease after washing. There is significant change in abrasion of those fabrics.
Modern Village-Neoteric Grid and Sustainable Energy with Dynamic Bangladesh
(Daffodil International University, 23-07-12) Hossain, Md. Shahariya; Hossain, Md. Rajib; Newaj, Md. Shah
Solar power is the process of converting solar energy directly into electricity via the use of photovoltaics (PV) or indirectly through the use of concentrated solar power. The photovoltaic effect is used by photovoltaic cells to convert light into an electric current. The Solar System is the only system in which a habitable planet has been observed, the only star we can observe up close, and the only planets we can explore with spacecraft. Understanding the creation and evolution of planets as well as the conditions required for life requires extensive investigation into the solar system. Bangladesh has high ambitions for solar and renewable energy. By 2030, the nation aims to produce 4,100 MW of sustainable energy, of which 2,277 MW will come from solar, 1,000 MW from hydropower, and 597 MW from wind. Wind power is the conversion of wind electricity to useful energy through the use of turbines that rotate to produce electrically. The power and wind speed are directly proportional. Fossil fuel supplies are diminishing daily. Due to a lack of electricity supply, Bangladesh’s rate of industrial development has showed down. Without significantly harming the environment, wind energy offers a big potential to lessen our dependency on conventional energy sources like as coal, gas, and oil. With an increase in GDP of about 7% in 2015, Bangladesh's economy is among those that are growing the quickest globally. About 51% of people in Bangladesh, especially in the disconnected areas, lacked a connection to power. Given the nearing exhaustibility of fossil fuels and the rapidly increasing need for electricity, the nation's lawmakers have shifted their emphasis to renewable energy sources like wind power in different organizational arrangements. Renewable energy from sources like solar, biogas, wind, and hydropower has grown in popularity in Bangladesh. The only electrical station in the country having a 230 MW electricity collection capacity is the hydroelectric project at Karnaphuli. The Kaptai Dam is located 65 kilometers above sea level in Kaptai, Bangladesh's Rangamati District, on the bank of the Karnaphuli River. It is a construction dam with a water storage capacity of 6,477 million cubic meters. The primary purpose of the reservoirs and dams was to generate hydropower electricity. It has been used for more than 20 years to efficiently create power using current wind turbines. China, United States, Germany, Spain, India 91424MW, 61091MW, 22959MW, 20150MW and the top five nations that use windmills to harvest electricity from the wind in 2013. The first wind power facility in Bangladesh began operations in 2005. Two projects in Bangladesh that produce wind energy are those at the Muhuri Dam and the one on Kutubdia Island. The initial grid-connected wind turbine in Bangladesh will be the Muhuri dam construction. Bangladesh can be found from 20.30- and 26.38-degrees northern latitude and 88.04- and 92.44-degrees eastern longitude. It has a 700-kilometer-long coast. Bangladesh ranks as one of the countries with the smallest per-person energy consumption. Every day, there is a greater and greater demand for electricity. Natural gas, a fuel which is primarily utilized in the electricity sector, may be found in Bangladesh's eastern region. The possibility for wind is the highest of any green power resource.
