Padma, a major river in Bangladesh is the main distributary of the Ganges flowing generally southeast for 120 kilometres to its confluence with the Meghna river. It has been traditionally considered a dominantly meandering river but recently switching over into a braided river due to its highly susceptible nature of erosion and deposition. To identify proper behavior and seasonal hydrodynamic variation of the Padma river, different hydrodynamic parameters have been included in this study. The reach is selected from Baruria transit at upstream to Mawa at downstream. Data of hydrodynamic parameters such as water level, velocity, discharge have been sorted, analyzed and plotted for the investigation of variation of various parameters during pre-monsoon, monsoon and post-monsoon seasons. The velocity, water level and discharge are found to be maximum during monsoon than pre-monsoon and post-monsoon. Discharge and water level approximately decrease in pre-monsoon and post-monsoon period by 76.3%, 75.7% and 59.3%, 57.4% respectively in comparison to monsoon period. From the data analysis, discharge and water level have been found to be maximum in monsoon 1998. It is also known that sediment transport rate is closely related to the velocity. The analysis also shows that velocity at monsoon period increase about 50% to 65% than pre-monsoon and post-monsoon period. Therefore during monsoon, high velocity results high sediment transport rate and ultimately contributes in erosion/deposition of river bed. It is hoped that the findings of this assessment will be helpful to understand the seasonal hydrodynamic nature of the Padma river and suggest possible future development works to be implemented on this river.

Our project is to develop a low cost, automatic, smaller and portable Satellite Tracker and Antenna management system useable for Satellite communication. We are using programmable microprocessor and embedded technology to develop this project. This project is based on GPS so that we can calculate, track and communicate with almost all the satellites orbiting the earth from anywhere of the globe. Now it is possible to develop complete portable satellite Ground Station using this technology.

Due to natural and manmade disaster, people are dying every year and a large number of people are becoming a victim of lack of proper surveillance data. A surveillance robot serves the purpose of monitoring the surrounding and provides enough data to act on the situation. This paper describes the development of a novel approach towards surveillance robots. The proposed robot is capable of providing live video footage, condition of the surrounding area by measuring temperature, humidity, amount of explosive gases, CO2 gas, flame, vibration and distance from obstacles. It is also capable of detecting a human & the chance of being alive and it has an arm to perform remote activity assisting the situation. The robot is built with aluminum and strong plastic. Because of continuous track, it can go through irregular surfaces. Besides, it has four helping legs, which have four motors with grip wheels that allow vertical movement. The whole robot is controlled by radio frequency which facilities long range wireless communication. The main objective to build the robot is to help the rescue workers and to knowthevictim’s condition in an underground hostage situation.

Main purpose of this paper is generation of power by speed breakers. It is for replacing common speed breakers with some technical mechanism. In this world, population is increasing rapidly and the sources of energy are lessening. To solve the problem, our paper concerns with the reuse of wasted energy which is produced by the vehicles passing over the speed breakers. The vehicles spin the rollers connected to generator which generates electricity. As the number of vehicles is increasing at fast rate, this process will be a striking path to produce electricity. It can be easily used in any place. By this mechanism, the energy which is saved in day can easily be used in night. On the other hand the cost of fabrication material is very low.

Production planning and control has crucial impact on the production and business activities of enterprise. In this paper a modified mathematical model is proposed for planning a single product production where its components are made from different sources. From review of previous research, it is observed that few authors have developed production planning model which is confined to only a single bill of material that is not affiliated with real situation. The major distinct feature of the proposed model is that it plans not only the finished product but also of its component. Finally, this model is applied numerically in production field and its feasibility and compatibility is examined.

Pharmaceutical industry in Bangladesh is one of the most developing industrial sectors. As a promising sector, pharmaceutical industry needs some empirical studies for its future development. In this research work, it is tried to analyze the current condition of the pharmaceutical sector and selects different strategies that are necessary for the development of this sector. The SWOT analysis is done to find out the strength, weakness, opportunity and threat (four factors) of the pharmaceutical sector; that may affect strategic planning and decision-making. Then four sub factors are selected for each of the four factors. These sub factors are used to form the SWOT matrix which gives four strategies such as SO (strengths-opportunities) strategies, WO (weaknesses-opportunities) strategies, ST (strengths-threats) strategies and WT (weaknesses-threats) strategies. After this, fuzzy TOPSIS method is implemented to find out the best strategy. According to the concept of the fuzzy TOPSIS in multiple-criteria group decision making (MCGDM) problem, an index of closeness coefficient (CC) is defined to determine the ranking order of all strategies by calculating the distance to the both fuzzy positive ideal solution and fuzzy negative ideal solution. It is found that WO (weaknesses-opportunities) strategy possess the higher closeness coefficient which makes it most appropriate strategy for the pharmaceutical industry in Bangladesh.
