In this paper we present a detailed review of the works on public key cryptography (PKC) in wireless sensor networks (WSNs). In the early days of sensor networks, public key cryptography was thought to be completely unfeasible considering its computational complexity and energy requirements. By this time, several works have proved that the lightwei

A Mobile Ad Hoc Network (MANET) represents a system of wireless mobile nodes that can freely and dynamically self-organize into arbitrary and temporary network topologies without the presence of any fixed communication infrastructure. Reliable routing and robustness of the network are two important issues for MANETs. In this paper we propose Neighb

The present paper discusses the development of a mathematical model for predicting the tangential cutting force produced in end-milling operation of medium carbon steel (S45C) using coated TiN insert under dry conditions and full immersion. It is difficult to predict accurately the cutting forces encountered in end milling operations due to large n

This paper describes mathematically the cutting force prediction model based on different cutting parameters in end milling of steel AISI1020. In this study, Cutting tests were conducted mainly on Vertical Machining Center for end milling of steel using coated TiN insert under dry conditions and full immersion cutting. The mathematical model for th

In this work, an Artificial Neural Network (ANN) model was developed for the investigation and prediction of the relationship between cutting parameters and chip serration frequency during high speed end milling of medium carbon steel (S45C). The input parameters of the ANN model are the cutting parameters: cutting speed, feed, and axial depth of c

The output parameter of the model was surface roughness. For this interpretation, advantages of statistical experimental design technique, experimental measurements, artificial neural network were exploited in an integrated manner. Cutting experiments are designed based on statistical three-level full factorial experimental design technique. A pred

Chip morphology under different cutting conditions is different. Serious vibrations are often encountered due to chip segmentation that limits material removal rates. In order to increase productivity, tool life and chatter suppression in the machining of Inconel 718, it is necessary to study the chip segmentation phenomena and its influencing fact

This book starts off with Chapter 1 which introduces us to qualitative research, an approach that does not deal with numbers per se, but, has guidelines and a systematic approach within a theoretical framework or design. The chapter also discusses the characteristics of qualitative research; and the differences between qualitative and quantitative

The present paper discusses a response surface methodological approach for the prediction of tangential cutting force produced in end-milling operation of Stainless steel (SS304). It is difficult to predict accurately the cutting forces encountered in end milling operations due to large number of independent variables involved. In this work, an app

Financing-to-value (FTV) policy is a macroprudential policy currently used by the central banks to maintain the stability of financial systems and prevent systemic risks. In Indonesia this is particularly the case in relation to financing of the property sector by Islamic financial institutions. This paper aims to analyse the impact of FTV policy o
