In the present study, the predictive model is developed to observe the effect of radial rake angle on the end milling cutting tool by considering the following machining parameters: spindle speed, feed rate, axial depth of cut, and radial depth of cut. By referring to the real machining case study, the second-order mathematical models have been developed using response surface methodology (RSM). A number of machining experiments based on statistical five-level full factorial design of experiments are carried out in order to collect surface roughness values. The direct and interaction effects of the machining parameter with surface roughness are analyzed using Design Expert software. The optimal surface roughness value can be attained within the specified limits by using RSM. The genetic algorithm (GA) model is trained and tested in MATLAB to find the optimum cutting parameters leading to minimum surface roughness. The GA recommends 0.25 μm as the best minimum predicted surface roughness value. The confirmatory test shows the predicted values which were found to be in good agreement with observed values. © 2014, Springer-Verlag London.

Multimedia security has become an active area of research in recent years due to the extensive growth and development of multimedia data exchange on the internet. A number of security techniques have been developed to deal with the problems of attackers and hackers. But, most of the existing security approaches do not provide reliable results under certain attacks. This research work presents a novel technique to deal with the security problems. This research work uses the digital watermarking process which embeds the original information into a digitalized signal. Strength and reliability are the two important qualities in watermark embedding. But, digital watermarking has its own limitations wherein the insertion of the original information into the cover image and identification of the exact location without degradation of the original image quality is difficult. In order to solve the problem in digital watermarking, this research work proposes a biogeography algorithm with GA optimization to find the optimal allocation of location in images to embed information. But, Genetic optimization algorithm has certain limitations such as slow convergence, less accuracy, etc. Hence, this research work uses Biogeography Particle Swarm Optimization (BPSO) and Biogeography Firefly optimization (BFA). Experimental results are carried out with standard images and the performances of three methods are compared based on the parameters like MSE, SSIM and PSNR. It is observed that BFA shows best results to different threshold values which results in better visual quality of watermarked images. © 2013 Praise Worthy Prize S.r.l. - All rights reserved.

Decreasing vibration amplitude during end milling process reduces tool wear and improves surface finish. Mathematical model has been developed to predict the acceleration amplitude of vibration in terms of machining parameters such as helix angle of cutting tool, spindle speed, feed rate, and axial and radial depth of cut. Central composite rotatable second-order response surface methodology was employed to create a mathematical model, and the adequacy of the model was verified using analysis of variance. The experiments were conducted on aluminum Al 6063 by high-speed steel end mill cutter, and acceleration amplitude was measured using FFT analyzer. The direct and interaction effect of the machining parameter with vibration amplitude were analyzed, which helped to select process parameter in order to reduce vibration, which ensures quality of milling. © 2010 Springer-Verlag London Limited.

This paper gives a contourlet transform with modified PSO (MPSO) for the feature enhancement, edge preservation and despeckling of SAR images. In this paper, despeckling and preservation of edges are combined with improved gain function that optimises the contourlet coefficients for the enhancement of quality of denoised image. Furthermore, global search algorithm such as MPSO algorithm is applied for the best result. Increase in convergence speed and reduction in premature convergence are possible with MPSO that produces new learning scheme and a mutation operator. Contourlet transform with MPSO is compared with some of the standard speckle reduction filters and wavelet transform with MPSO. Experimental results show that the contourlet transform with MPSO gives better quality of image. Copyright © 2015 Inderscience Enterprises Ltd.

Bhavani is one of the important Rivers in the Tamilnadu. Many industries, particularly textile processing units, tanneries, and distillery units, are situated on the banks of Bhavani River. These industries let out untreated and partially treated effluents in to the river stream. It is, therefore, decided to study the quality of water and to estimate its pollution load in the River Bhavani near Mettupalayam region. Samples of water were collected at selected points and physio-chemical examinations were carried out. It was observed that at the start at the place before the mixing of effluent the water quality in river was good, but showed a progressive decline from its origin to further distances as it passes through human settlements and industrial areas.

In the advent of modernization, pollution problems have also emerged in various forms. Effluent treatment involving biodegradable organic wastes can be treated biologically in most cases. Activated sludge process is used in the studies. The organic waste is introduced into a reactor where bacterial culture is kept in suspension. Sludge volume index is used to ascertain the settling characteristics. Settling studies were performed on dairy waste for different initial mean cell residence time and Mixed Liquor Suspended Solids (MLSS) concentrations. To prepare the sludge for various θc (7, 9, 11, 13 and 15) a batch reactor of 20 liters capacity was used (A bench scale settling tests). Further all these equations were combined to form a model connecting three parameters viz. Mixed liquor suspended solids concentration, Sludge Volume Index (SVI) and Mean Cell Residence time (MCRT). This model could be used to help the operator of ASP to compute the return sludge and also the sludge volume index values can help to maintain the desired underflow concentrations. © 2011 CAFET-INNOVA TECHNICAL SOCIETY.

The prediction of delta ferrite content expressed in terms of ferrite number in austenitic stainless steel welds is very helpful in assessing its performance. The final ferrite content determines the properties of weldments such as strength, toughness, corrosion resistance, and phase stability. This paper presents a study on the effect of process parameters on ferrite number in 202 grade stainless steel gas tungsten arc welded plates (GTAW). Experiments were conducted based on response surface methodology. The ferrite number was determined by using a ferrite scope and by using DeLong diagram. A mathematical model was developed correlating the important controllable GTAW process parameters like welding gun angle, welding speed, plate length, welding current, and shielding gas flow rate with ferrite number. The adequacy of the model was checked using analysis of variance technique. The developed model is very useful to quantitatively determine the ferrite number. The main and interaction effects of the process parameters are presented in graphical form that helps in selecting quickly the process parameters to achieve the desired results. © 2012 Springer-Verlag London Limited.

In recent years, the usage of Rice husk ash (RHA) and Metakaoilin (MK) as a pozzolonic material for the preparation of cement concrete had become more important than any other material. The manufacture of Portland cement (PC) is not eco friendly; the content of pozzolonic material in cement mortar exhibits a considerable increase in strength and durability properties. This paper gives a review about the use of RHA and MK as not only a partial replacement for cement but also a replacement for the influence of toxic waste. The collection of literature survey report elaborated that the usage of RHA and MK is an efficacious mineral admixtures, which cause a large betterment in the filling of pore structures. In addition to this it increases the resistance of the concrete to environmental effects, and gives better solutions for the abundant waste of RHA produced from Agricultural product in India. © Research India Publications.
