Artificial Neural Network Algorithm for Predicting the Surface Roughness in End Milling of Inconel 718 Alloy
Research Output | Dar Al-hikmah Library | IIUM Only

Surface roughness is one of the important factors for evaluating workpiece quality during the machining process because the quality of surface roughness affects the functional characteristics of the workpiece such as compatibility, fatigue resistance and surface friction. The factors that affect the surface roughness during the end milling process

State of the Art Review on Walking Support System for Visually Impaired People
Research Output | Dar Al-hikmah Library | IIUM Only

The technology for terrain detection and walking support system for blind people has rapidly been improved the last couple of decades but to assist visually impaired people may have started long ago. Currently, a variety of portable or wearable navigation system is available in the market to help the blind for navigating their way in his local or r

Modeling the Powder Compaction Process Using the Finite Element Method and Inverse Optimization
Research Output | Dar Al-hikmah Library | IIUM Only

This paper focuses on studying and adapting modeling techniques using the finite element method to simulate the rigid die compaction of metal powders. First, it presents the implementation of the cap constitutive model into ABAQUS FE software using the closest point projection algorithm. Then, an inverse modeling procedure was proposed to alleviate

Impact of Teachers’ Professional Development on School Improvement—an Analysis at Bangladesh Standpoint
Research Output | Dar Al-hikmah Library | IIUM Only

This study seeks to describe the teachers’ professional development activities in Bangladesh and explores the hypotheses about the relationship between teachers’ traditional professional development activities and school improvement. Data from a representative sample of City secondary schools from Bangladesh (n = 127) were gathered through ques

Design and Data Analysis for a belt-For-blind for Visual Impaired People
Research Output | Dar Al-hikmah Library | IIUM Only

This research designs a new walking support system for the blind people in order to navigate without any assistance from others or using any guide cane. With the help of this device, a user can move independently and able to walk freely almost like a normal person. In this research, a belt for blind wearable around the waist is equipped with four u

Study on air-Cushion Tracked Vehicle Performance: Theoretical Analysis and Experimental Validation
Research Output | Dar Al-hikmah Library | IIUM Only

This paper presents a theoretical framework for simulating the vehicle ground contact pressure distribution, vehicle sinkage and the tractive performance of an air-cushion tracked vehicle. It takes into account track sizes of the vehicle, air-cushion effective area as well as the terrain nominal pressure and vehicle sinkage. The subsequent validati

Design and Modeling of Silicon MEMS Accelerometer
Research Output | Dar Al-hikmah Library | IIUM Only

In developing Micro Electro Mechanical Systems (MEMS), Finite Element Analysis (FEA) is usually relied upon to study these micro-structures in determining stress, deformation, resonance, temperature distribution, electromagnetic interference, and electrical properties. With this kind of approach, the performance of the devices can be easily expande

The Arab Reawakenig: International Responses and Implicarions
Research Output | Dar Al-hikmah Library | IIUM Only

This paper, first of all, argues that the mass uprisings in the Middle East and North Africa (MENA) in 2011 are best described as the “Arab Reawakening.” Then it delves into an explanation of failures of international commentators to predict the uprisings in MENA. In assessing the international responses to the 2011 Arab Reawakening, an attempt

Development of an Artificial Neural Network Algorithm for Predicting the Cutting Force in End Milling of Inconel 718 Alloy
Research Output | Dar Al-hikmah Library | IIUM Only

To predict the required cutting force is necessary to realize the potentials of difficult-to-cut materials and get better efficiency. Cutting force is a critical and important target while machining because the change of it will affect surface finish, tool wear, vibration etc. The forces that are developed during the milling process can directly or

Assessment of Performance of Uncoated and Coated Carbide Inserts in End Milling of Ti-6al-4v Through Modelling
Research Output | Dar Al-hikmah Library | IIUM Only

Materials used in the manufacturing of aero-engine components generally comprise nickel and titanium base alloys. A major requirement of cutting tool materials used for machining aero-engine alloys is that they must possess adequate hot hardness to withstand the elevated temperatures generated at high speed conditions of aerospace alloys. Most cutt
