Can we characterize the wavelets through linear transformation? the answer for this question is certainly YES. In this paper we have characterized the Haar wavelet matrix by their linear transformation and proved some theorems on properties of Haar wavelet matrix such as Trace, eigenvalue and eigenvector and diagonalization of a matrix.

Viatra2 (VIsual Automated model TRAnsformations) is a general-purpose model transformation engineering framework that aims at supporting the entire life-cycle, i.e. the specification, design, execution, validation and maintenance of transformations within and between various modeling languages and domains in the MDA. This paper reports on the current status of the tool and sketches some future ...

in this investigation, continuous cooling transformations and microstructures have been studied in detail in a low carbon ti-nb bearing microalloyed steel by means of dilatometry, metallography and hardness measurements. the results indicate that when the cooling rate is greater than 1˚c/s, the dilatation curve is associated with a major dilatation at relatively low transformation temperatures,...

iran's health system is in the serious need of reconstructing its infrastructures, a significant part of which is health technologies. an untapped market of 80 million people will be open to technologies of the world through iran's entry to post-sanctions era. health technology assessment projects date back to nearly eight years ago in iran. however, given the current circumstances, its applica...

introduction: resistance of pathogenic organisms to countenance antibiotics has become a worldwide problem with serious consequences on the treatment of infectious diseases. the aim of this study was to evaluate antibiotic resistance and also the detection of transferred antibiotic resistance by plasmid in clinical proteus isolates. materials and methods: a total of 250 urine samples were colle...

in this paper, we study the numerical solution of hybrid fuzzy differential equations by using differential transformation method (dtm). this is powerful method which consider the approximate solution of a nonlinear equation as an infinite series usually converging to the accurate solution. several numerical examples are given and by comparing the numerical results obtained from dtm  and  predi...

Mycobacterium smegmatis PTCC 1307 (CIP 73.26) was used as a microbial agent to produce androsta-1,4-diene-3,17-dione (ADD) and androst-4-ene-3,17-dione, two useful precursors in the synthesis of steroid drugs. The side chain of cholesterol, as the substrate, was selectively cleaved in the presence of five enzyme inhibitors. An intermediate structure with intact side chain, cholest-4-ene-3-one, ...

malignant transformation of ameloblastomas arising from an odontogenic cyst or de novo is wellrecognized. malignancies in ameloblastomas may involve metastasis or a local dysplastic change in the tissue. the latter are classified as ameloblastic carcinomas. a 75-year-old male presented with a mandibular cystic swelling, with no evidence of metastasis. dysplastic ameloblastic cells with spindlec...
