In this research, formation of nanocrystalline Ni3Al intermetallic from Ni and Al elemental powders by mechanical alloying (MA) process and its characterization was investigated. Therefore, the evolutions in microstructure such as phase transformation, oxidation in air and introduction of Fe impurity from milling media after MA were evaluated using XRD, Rietveld refinement, TEM, SEM, EDS and IC...

This paper introduces the effective speckle reduction of synthetic aperture radar (SAR) images using inner product spaces in undecimated wavelet domain. There are two major areas in projection onto span algorithm where improvement can be made. First is the use of undecimated wavelet transformation instead of discrete wavelet transformation. And second area is the use of smoothing filter namely ...

In this paper we portrait Model Driven Architecture (MDA) as an approach to derive products in a particular class of software product families, i.e. a configurable product family. The main contribution of this paper is that we relate MDA to a configurable software product family and discuss the mutual benefits of this relation. With respect to variability management, we identify two main benefi...

The concept of product encryption is resident in the majority of symmetric block ciphers. Along with product encryption, two properties were also defined by Shannon, namely diffusion and confusion. In a product cipher such as a Feistel Network (FN), or generally a Substitution Permutation Network (SPN), diffusion is dependent upon two types of primitives, the nonlinear transformation and the sw...

Thermal processing with heat exchangers is a widely-used method for improving the safety and extending the shelf life of many liquid food products (milk, juices, etc). It is also employed for inducing transformation of selected food constituents, like starch, as a way to promote food characteristics which are appreciated by consumers, like texture. Fluid flow, heat transfer and transformation p...

The 22-KDa is the protein product of human growth hormone (hGH) gene isoform 1 of the pituitary hormone (Ahmed et. al., 1993). hGH gene was amplified with PCR from human growth hormone cDNA clone by specific designed primers containing extraterminals having Nco I and Bam HI restriction sites. The PCR product obtained was analyzed by enzyme digestion and DNA sequencing. The product was cloned in...

the synthesis of nano- structured cobalt through a controlled chemical process followed by heat treating at various temperatures is studied. the product is characterized by icp, xrd, fesem , and tem, indicating that the as- synthesized particles have an amorphous structure with 1.76 for co/b ratio, an average size of 50 nm. the transformation of intermediate phases into single phase nano- cryst...

Recommended by Teodor Bulboac˘ a We give new proof of a four-variable reciprocity theorem using Heine's transformation, Watson's transformation, and Ramanujan's 1 ψ 1-summation formula. We also obtain a generalization of Jacobi's triple product identity.

Model-driven software product lines are an emerging topic in research and industry, as they promise higher development speed and easier adaptability to customer needs. The generation facilities for the products, however, still have a static nature: specification languages for the composition of model transformations sequences (model transformation workflows) up to now only support the specifica...
