The Mamdani Fuzzy Inference Algorithm New
Research Output | Dar Al-hikmah Library | IIUM Only

Fuzzy logic is simply the operations of fuzzification, conjunction, disjunction, complement,defuzzification etc. on fuzzy sets. It is generally carried out using the degree of membership that has been discussed so far. The fuzzification step is usually performed on data being input into a system. In the Mamdani fuzzy inference methodology this fuzz

Relationship Between Machining Variables and Process Characteristics During Wire Edm New
Research Output | Dar Al-hikmah Library | IIUM Only

Abstract. Wire EDM is in use for a long time for cutting punches and dies, shaped pockets and other machine parts. Surface finish of the machined surface mainly depends on current and voltage used during machining. In the present work experimental investigations have been conducted to establish relationships job surface finish with current and volt

Influence of Machining Parameters on Surface Roughness During Edm of Mild Steel New
Research Output | Dar Al-hikmah Library | IIUM Only

Abstract. The present paper reports on the influence of process parameters on surface roughness of mild steel during EDM using a copper electrode. Surface quality was evaluated on the basis of work surface roughness, micro cracks and thickness of the recast layer. Current, pulse-on time, pulse-off time and voltage were the variable parameters for t

Features of Electrode Wear During Edm of Mild Steel with tac-Cu Powder Compacted Electrodes New
Research Output | Dar Al-hikmah Library | IIUM Only

Abstract. Features of tantalum carbide-copper powder compacted electrodes during EDM of mild steel have been studied. It was found that during EDM electrode wear increases with increase in current and spark on-time. Electrode wear is inversely proportional to spark off-time. Due to increase in off-time, energy density decreases that caused reductio

A Comparative Study on Work Surface Hardness Edmed by ta-C Powder Compacted and Copper Electrodes New
Research Output | Dar Al-hikmah Library | IIUM Only

Abstract. Tantalum-carbide and solid copper electrodes were used to EDM mild steel. Current, spark on-time and off-time were taken as the machining variables. It was found that work surface hardness increases while machining with high current and on-time. However, increase in spark off-time results decrease in work surface hardness. It was also fou

Developments in Edm Process Variables New
Research Output | Dar Al-hikmah Library | IIUM Only

Abstract. The electrical discharge machining (EDM) process parameters (both the input and output) are presented. The input variable of EDM presented here are electrical and non-electrical ones. These are peak current, discharge voltage, pulse cycles (duration and interval), electrode‘s polarity and gap. The recent advances in areas of both the in

Differential Image Compression for Telemedicine: a Novel Approach New
Research Output | Dar Al-hikmah Library | IIUM Only

Telemedicine is one of the most emerging technologies of applied medical sciences. Medical information related to patients is transmitted and stored for references and consultations. Medical images occupy huge space; in order to transmit these images may delay the process of image transmission in critical times. Image compression techniques provide

An Empirical Assessment of Islamic Leadership Principles New
Research Output | Dar Al-hikmah Library | IIUM Only

The main purpose of the present paper is to document some Islamic leadership principles of management. The paper equally examines the leadership function as adopted by academic administrators within the International Islamic University, Malaysia vis-a-vis Islamic principles of management. The whole process is an attempt to conduct an empirical stud

Bank Rakyat Malaysia: Vision Remains While Mission is Revisited New
Research Output | Dar Al-hikmah Library | IIUM Only

The slogan, “of the people, for the people, by the people” comes home. Bank Rakyat Malaysia (BRM) offers a different kind of retail banking. Bank Rakyat underwent a drastic evolution from a cooperative system of management to a highly creative market entity ready to face the very aggressive competitive market forces of the Islamic banking and f
