Chatter is an unwanted but sometimes unavoidable phenomenon in computer aided machining. The term defines the self-excited violent relative dynamic motion between the cutting tool and workpiece. Experimental investigations have been conducted on the chips and common types of discreteness in the form of serrated saw teeth have been identified. It ha

Abstract. In this paper, we consider a problem on finding the number of different single connected component containing a fixed root for a given number of vertices on semi-infinite Cayley tree. The solution of this problem is the well known Catalan numbers. The result is then extended to the complete graph. Then, we gave a suitable estimate for the

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

The intent of this paper is to present the flaws and weaknesses of Kim et al.'s timestamp-based password authentication scheme using smart cards. We prove that, in spite of the improvement of Yang-Wang-Chang's scheme, Kim et al.'s solution is still vulnerable to a type of forgery attack. We also note down how the flaw could be overcome

INTRODUCTION The architecture and operational methods of Future Internet (FI) are not yet clear. So, proposing any sp

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

1. A retrospective study was conducted to explore the importance of CYP2C9 genotyping for the initiation and maintenance therapy of warfarin in clinical practice. A total of 191 patients on warfarin therapy in a local hospital were recruited after written informed consent. Their medical records were reviewed and no intervention of warfarin dose was

In recent years, emotional personality has found an important application in the field of human machine interaction. Interesting examples of this domain are computer games, interface agents, human-robot interaction, etc. However, few systems in this area include a model of personality, although it plays an important role in differentiating and dete

The supercritical carbon dioxide (SC-CO2) was successfully used in the complete sterilization as well as simultaneous extraction of oil from screw pressed palm fruit fiber. The studies were conducted at different temperatures (40, 50, 70 ◦C) and pressures (13.7, 20.7MPa) for 60 min of extraction period. The bacteria, gram negative (Bacillus), pre
