Purpose: The main objective of this paper is to investigate the effect of workpiece preheating with high frequency induction heating on improvement of machinability of Ti-6Al-4V during end milling using PVD TiAlN coated inserts. Tool life, cutting force and vibration were investigated during the experiments. Design/methodology/approach: End milling

An algorithm is proposed for processing and analyzing surface electromyography (SEMG) signals using wavelet transform and Higher Order Statistics (HOS). EMG signal acquires noise while travelling though different media. Wavelet denoising is performed in this research for initial EMG signal processing. With the appropriate choice of the Wavelet Func

In this work, an artificial neural network (ANN) model was developed for the investigation and prediction of the relationship between cutting parameters and surface roughness during high speed end milling of nickel-based Inconel 718 alloy. The input parameters of the ANN model are the cutting parameters: cutting speed, feed, and axial depth of cut.

This chapter provides a broad view of Malaysia's foreign policy. It applies the "funnel of causality" to explain the various factors that shape the foreign policy of Malaysia. This is followed by an analysis of the aims and objectives of Malaysia's foreign policy. Finally, it provides a survey of foreign policy of Malaysia under the

Intrapulmonary bronchogenic cyst is a rare congenital lesion originating from abnormal budding of the embryonic foregut. It is less common than mediastinal bronchogenic cyst. We describe a case of intrapulmonary bronchogenic cyst and discuss the treatment of this condition.86CASE REPORT JUMMEC 2008: 11(2) Case Report A 51-year old man, who was an e

The present study was conducted to compare the water quality and plankton availability between perennial and non-perennial ponds in Bangladesh for a period of six months during October 2004 to March 2005. All water quality parameters in perennial ponds were statistically different (p< 0.05) than that of non-perennial ponds except temperature. F

This paper presents our ongoing work in developing an agent architecture to support personal mobility in IP networks. In particular, the paper discusses a tracking mechanism that facilitates location management using agents where both host and user mobility is accorded by the network. Towards this end, a multi-layered agent architecture is proposed

An approach is presented to facilitate location management of mobile hosts using a distributed intelligent architecture. Intelligence is imbued onto an IP-based network as an overlay to provide mobility services. The overlay consists of a three-layered multi-agent architecture that would provide the necessary signaling and control information to su

With the advent of the handheld devices and multimedia applications, there has been an increasing interest for mobile multicast. IETF proposes two approaches. The first approach is Bi-directional (BT), where the mobile node subscribes to a multicast group through its home network. The second approach is Remote Subscription (RS), where the mobile no
