FIELD ORIENTED SPEED CONTROL OF INDUCTION MOTOR DRIVES Khatoon, Afsana; Rahman, Md. Shaifur This paper presents the field oriented control of a three phase induction motor up to base speed to investigate the improved performances of an induction motor driven by a PI controller by using a commercially available software package Matlab/Simulink. The concept of field – orientated control (FOC), an indirect method of vector control method, has been selected to be the motion control technique because it produces controlled results that have a better dynamic response to torque variations in a wider speed range compared to other scalar methods. A PI type speed controller has been designed to investigate the performance of IM drives.

INTREGRATION OF TELECOMMUNICATION IN PASSPORT MAKING PROCESS - A PSEUDO MEANS TO REDUCE TRAVEL DEMAND AND OTHER SUFFERINGS Kabirul Islam, Major Md.; Hoque, Md. Shamsul Telecommunication or Information Communication Technologies (ICT) that is changing rapidly every aspects of life, is also bringing significant changes in the traditional concept of transportation. Like other telecom enabled services (1), telecom enabled passport making process has the potential to reduce significant travel demand and associated sufferings of the clients, hence of the society. On this consideration, existing passport making, renewal, amendment processes have been critically analyzed in this paper to identify the amount and pattern of physical trips and associated sufferings involved in these processes as well as to explore the way of how telecommunication or ICT can gainfully be integrated with the system. The analysis found that for the purpose of passport making, renewal and amendement process daily approximately 18,000 trips are made around Dhaka passport office. Most of these trips are made during the peak periods availing the highly congested city transport network spending huge amount of fuel, time, money and labor. It is further estimated that effective integration of ICT in the existing system can reduce or convert 63-75 percent physical trips to Fuel Free (FF) electronic trips. In addition, ICT enabled system can also speed up and simplify the process, minimize massive paper works and corruptions, ease up the social sufferings, and increase the productivity of the system. It is expected that this study would help the transport planners and policy makers’ better way of understanding how the ICT can reduce the need for travel demand in different fields and thereby solve local traffic induced problems.

AN ANALYSIS OF ALTERNATIVE INDUSTRIALIZATION STRATEGIES FOR DEVELOPING ECONOMIES Jahan, Masud; Rashid, Samiur Industrialization is the process of social and economic change whereby a human group is transformed from a preindustrial society into an industrial one. Import Substitution Industrialization (ISI) is an industrialization policy based on the premise that a country should attempt to reduce its foreign dependency through the local production of industrialized products. Because of limitations of ISI, the concept of Export-led industrialization was supported by economists. Export-led industrialization (ELI) is an industrialization policy aiming to speed-up the industrialization process of a country through exporting goods for which the nation has a comparative advantage. Export-oriented industrialization is often contrasted with import substitution industrialization. The objective of this paper is to critically appraise the role of Easy ISI strategy in economic development.

ANALYSIS OF MODELING RESULTS FOR RIVER BANK PROTECTION OF THE MOST VULNERABLE PART OF TAZUMUDDIN UPAZILA UNDER BHOLA DISTRICT Aziz, Md. Abdul; Alam, Rubayat; Mahamud, Upal; Haque Khan, Zahirul Bhola is the largest Island of Bangladesh situated in the south central region (latitude approximately from 430000N to 525000N and longitude 555000E to 590000E) of Bangladesh in the highly dynamic Meghna Estuary. In recent years the erosion along eastern shoreline of Bhola Island has become a serious issue. Attempts are taken to establish the base line condition to simulate the natural phenomena. Baseline condition for Tazumuddin Upazilla (under Bhola district) has been developed based on hydrodynamic and morphological modelling and historical data of bank line shifting, thalweg line shifting, bathymetric data, char movement etc. To calibrate and validate the model water levels and discharge are successfully calibrated. From modeling result, erosion/deposition pattern at and outside the protective works, new vulnerable areas due to revetment have been identified. Hydrodynamic (HD) simulations during ebb tide the maximum depth integrated near bank velocity is found within the range of 1.5-3.0 m/s along the riverbank of Tazumuddin and 1.0-1.5 m/s along the riverbank of Lalmohan. Morphological simulation shows the channel is further extended towards the south-east part. Further computational simulation showed that channel in front of Tazumuddin become deeper and it is extended more towards the south-east direction. From bathymetry survey data in May, 05 it is found that there is a tendency to deepen the channel in front of Tazumuddin where protective work was suggested and the deep channel is further extended towards south-east direction like simulation result. So it can be concluded that simulation result and real condition near Tazumuddin follows the same trend of channel development.
