Proper understanding on the thermo chemical properties of biomass is necessary for the design of thermo-chemical conversion systems. The present study was conducted for the selected species of Bangladeshi biomasses. In this study seven differenttypes of biomass from Bangladeshi agriculture residues such as rice husk, rice straw, jute stick, sugarca

In this research, an experimental investigation was carried out at the International Islamic University Malaysia - Low Speed Wind Tunnel facility on a generic model of a hybrid lifting hull. Based on the historical trends of non-rigid airships, the fineness ratio of the said hull has been selected equal to 4. Free stream velocity was kept at 20 mâˆ

It is well known that hydrogen has less undesirable exhaust emissions as compared with other types of liquid fuels. It can be used as an alternative fuel for a hybrid buoyant aircraft in which half of the gross takeoff weight is balanced by the aerostatic lift. In the present study, weight advantage of liquid hydrogen as an ideal fuel has been expl

There seem to be a lot of robots that have been built up until today. Basically, the creation of robot is supposed to be a helper for a human. Robot will replace human whenever the task is really difficult or dangerous to be done by human. Recently, the robots that have been created were made reconfigurable. The purpose is to make the robot to func

A charge controller that includes an input interface that receives input DC electrical signals. A converter section converts the input DC electrical signals to output DC electrical signals. Control means is operably coupled to the converter section. The control means includes means for operating the converter section at an estimated maximum power p

As many of the high-end functions and services have been increasingly supported by the expansion of information technology (IT), it has become salient to explore any factor that may make individuals more prone to use it. When it comes to the user, technological and contextual features, there may be quite a difference in settings that are profession

Wing alone models are usually tested in wind tunnels for aerospace applications like aircraft and hybrid buoyant aircraft. Raw data obtained from such testing is subject to different corrections such as wall interference, blockage, offset in angle of attack, dynamic pressure and free stream velocity etc. Since the flow is constrained by wind tunnel

The main focus of this study is to performance test of a one cylinder four stroke ZS1115 diesel engine running by diesel fuel, raw preheated soybean oil fuel, mixture of 80% diesel fuel & 20% raw preheated soybean oil fuel, mixture of 50% diesel fuel & 50% raw preheated soybean oil fuel, mixture of 30% diesel fuel & 70% raw preheated so

This research approach a study with comparison of position sensorless control schemes based on back-electromotive force (back-EMF) estimation in permanent magnet synchronous motors (PMSM). The characteristics of the estimated back-EMF signals are analyzed using various mathematical models of a PMSM. The transfer functions of the estimators, based o

The aim of the present study is to analyze the performance, emission and combustion characteristics of a variable compression ratio (VCR), compression ignition (CI) engine using a suitable biodiesel as fuel. The biodiesel selected to conduct this experimental investigation is Karanja biodiesel. The selection of Karanja biodiesel is based on an exte
