Distance Measuring Equipment (DME) is based on the radar principle and provides information of distance (slant range) from the aircraft to the ground station. DME collocated with other navigational instrument (i.e. VHF Omnidirectional Range) allows aircraft to determine its location (longitude, latitude, and altitude) during flying. The Federal Aviation Administration’s (FAA) has proposed Alternative Position, Navigation, and Timing (APNT) architecture when Global Navigation Satellite System...

Hospital beds and other similar types of beds are used not only in hospitals, but also in other health care facilities and settings, such as nursing homes, assisted living facilities, outpatient clinics, and in home health care. There has more variations in the design of hospital bed and no one is designed with considering anthropometric data of Bangladesh. Anthropometry involves the systematic measurement of the physical properties of the human body, primarily dimensional descriptors of body size...

With introduction of Jet powered Aircraft in 1950s Engine Jet Noise menace. With the current rate of growth of aviation and extensive utilization of jet powered commercial airliners it is expected that total aviation (civil and military) is slightly to go by more than 4%. In these aircraft, modern technologies are being used where the use of jet engines is inescapable. All types of engines are generating noise which has negative impact on environment as well as human being. Although individual aircraft...

It is an established fact that the grain size of the steel has a marked impact on its mechanical properties. Steel with large grain size has lower yield strength, tensile strength, impact toughness, fatigue life and susceptibility to brittle fracture while has better creep resistance. Besides this it also affects the corrosion resistance and other properties of the steel. The purpose of this paper is to establish a definite mathematical relationship between the ferritic, pearlitic and average grain...

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;...

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...

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...

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...

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. ...
