The present paper discusses the development of the first and second order models for predicting the tangential cutting force produced in end-milling operation of medium carbon steel. The mathematical model for the cutting force prediction has been developed, in terms of cutting parameters cutting speed, feed rate, and axial depth of cut using desig

The paper presents a systematic procedure and details of the use of experimental and analytical modal analysis technique for structural dynamic evaluation processes of a vertical machining centre. The main results deal with assessment of the mode shape of the different components of the vertical machining centre. The simplified experimental modal a

The present paper discusses the development of a mathematical model based on statistical analysis for predicting the chip serration frequency in end-milling operation of steel AISI1020 using coated TiN insert under dry conditions and full immersion cutting. A small CCD with 2 blocks and 5 replication of centre point in each factorial block was sele

In this research, 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 o

A Mobile Ad Hoc Network (MANET) is built on the fly where a number of wireless mobile nodes work in cooperation without the engagement of any centralized access point or any fixed infrastructure. Two nodes in such a network can communicate in a bidirectional manner if and only if the distance between them is at most the minimum of their transmissio

Increased polyamine concentrations play an important role in the development of cancer at all stages, from initiation through to maintenance of the transformed phenotype. One way cancer cells accumulate increased concentrations of polyamines is by increased uptake of preformed polyamines via their PTS(polyamine transport system). The PTS is promisc

This paper presents a detailed review of remote user authentication schemes with smart cards based on bilinear pairings. The first scheme regarding this was proposed by Manik et al. in 2006, which had been modified and improved later in several ways. Here, we analyze all the related proposed schemes, point out their weaknesses and flaws, and note d

Problem statement: The present study investigates the ability of the pTok47 supervirulence plasmid form Agrobacterium tumefaciens A281 to enhance genetic transformation in Hevea brasiliensis. Approach: Hevea anther callus was transformed via Agrobacterium-mediated genetic transformation using two strains of Agrobacterium (GV2260 and GV3850) harbori
