Tool Wear and Process Cost Optimization in WEDM of AMMC using Grey Relational Analysis

Image
Abstract— Wire Electrical Discharge Machining (WEDM) endorsed sensation in the production of newer materials, especially for the aerospace and medical industries. Using WEDM technology, convoluted cuts can be made through difficult-to-machine electrically conductive components with the high degree of accessible accuracy and the fine surface quality make WEDM priceless. In other hand Aluminum Metal Matrix Composites (AMMCs) are the precise materials for marine, automobile, aerospace, defense, and sports industries which are difficult to cut by conventional methods of machining. In this paper an optimal set of material and machining parameters is derived using hybrid approach called grey-fuzzy approach. For this AMMC samples are produced as per the taguchi experimental design by considering combined material and wire EDM parameters and machined using wedm machine. The obtained responses such as kerf width, tool wear, process cost and surface roughness are optimized using grey-fuzzy appr…

Gene Expression Chromosomal Correlations in Tumors of Mesodermal Origin: The Case of Rhabdomyosarcoma and Acute Lymphoblastic Leukemia

Image
Abstract-since the advent of high throughput methodologies, like microarrays, the load of genomic data has increased geometrically and along with that the need for computational methods which will interpret these data. In the present work we have studied the common gene expression patterns between two tumor cell types of mesodermal origin. In particular, we have attempted to find causal relations between gene expression levels with respect to chromosomal location. We have found that several genes manifested significant relations, using regression analysis and as such they could pose interesting targets for further investigations. This type of analysis can lead to the understanding of the common mechanisms that transform physiological cells to malignant, as well as it reveals a new holistic way to understand the dynamics of tumor onset as well as the mechanistic of oncogenic drivers. Such approaches could prove to be useful in the prediction of genomic targets that could be further stu…

Mechanical properties of thermoset-metal composite prepared under different process conditions

Image
Abstract— This paper reports a study on the morphology and mechanical behavior of a thermoset-metal composite used in prototype molds as a function of the process conditions. The investigation of the mechanical properties of epoxy-aluminum specimens post-cured using different routines showed that they are related to the self-controlled diffusion characteristic of thermoset polymeric systems. A high-temperature post-cure routine resulted in higher values for the modulus, stiffness and glass transition temperature, Tg, for the specimens. The fracture surfaces analysis showed the presence of defects, which appeared as empty spaces in the epoxy matrix, due to the mixing and casting process. The defect size and the specimen strength showed a direct correlation. The Weibull modulus was 7.95 for the epoxy specimens characterizing low toughness and the presence of defects in the material, as revealed by fractography. The probability of failure increased rapidly to 50% for applied stress great…

Nonlinear Dynamic Time History Analysis of Multistoried RCC Residential G+23 Building for Different Seismic Intensities

Image
Abstract— In this paper study of nonlinear dynamic time history analysis of Twenty three storied RCC residential building considering different seismic/earthquake intensities is carried out and response of such building due to earthquake is studied. The building under consideration is modeled with the help of SAP2000V.14.00 software. Five different time histories have been used considering seismic intensities V, VI, VII, VIII, IX and X on Modified Mercalli's Intensity scale (MMI) for developing the relationship between seismic intensities and seismic responses. The outcome of the study shows similar variation pattern in Seismic responses i.e. base shear and storey displacements with intensities V to X. From the study it is recommended that analysis of multistoried RCC building using Time History method became necessary to ensure safety against earthquake force.Keywords—Multistoried buildings, Scaling, Seismic responses, Time history analysis.Click here to Download Full PaperAD Pub…

Design, Analysis & Performance Check of A Multi-Story (G+23) RCC Building by Pushover Analysis using Sap 2000

Image
Abstract— Pushover analysis is one of the most-used nonlinear static procedures for the seismic assessment of structures, due to its simplicity, efficiency in modeling and low computational time. The previous studies about pushover analysis are almost based on symmetric building structures and unidirectional earthquake excitation. This analysis is conducted to evaluate the seismic capacities of a asymmetric-plan building. The seismic response of RC building frame in terms of performance point and the effect of earthquake forces on multi storey building frame with the help of pushover analysis is carried out in this paper. In the present study the building frame is designed as per IS 456:2000 and IS 1893:2002. The main objective of this study is to check the kind of performance a building can give when designed as per Indian Standards. The pushover analysis of the building frame is carried out by using structural analysis and design software SAP 2000 (version 14).Keywords—Capacity Curv…

Preparation of activated carbon from orange peel and its application for phenol removal

Image
Abstract— Activated carbon obtained from orange peel (ACO) was used as a phenol adsorbent. ACO was characterized by X-ray diffraction, Raman spectroscopy, scanning electronic microscopy (SEM) and energy dispersive spectroscopy (EDS). The functional groups present on the sample, were determined by Boehm titration, and it was also determined the point of zero charge (pHpzc). ACO is mainly constituted by micropores, and its structure is turbostratic and lamellar with inorganic impurities. The Boehm titration indicated the basic behavior of the sample. The phenol optimum dosage was 0.1 g/50 cm3 which was determined by the adsorption study. The maximum adsorption level was in the pH range of 4-8 and its kinetics was described by a pseudo second order model. The equilibrium data have fit very well the Langmuir and Sips isotherms models.Keywords—adsorption, agricultural waste, biomass, orange peel, phenol.Click here to Download Full PaperAD Publications is a rapidly growing academic publis…
