Software transformation methods are enacted during a migration project to perform the technical transition of a legacy system to a new environment. A critical task of each project is to construct a situation-specific transformation method. In this paper, we categorize current Situational Method Engineering (SME) approaches that support the construction of situation-specific transformation metho...

the aim of this study is to analysis and identify the methodological, conceptual and structural approaches to the fundamental transformative documents of iranian general education system. to achieve this goal, a thematic method with a qualitative analysis approach was used, in order to gather the data and identify themes, theoretical foundations of transformation document, fundamental document ...

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.

We construct families of bispectral difference operators of the form a(n)T + b(n) + c(n)T where T is the shift operator. They are obtained as discrete Darboux transformations from appropriate extensions of Jacobi operators. We conjecture that along with operators previously constructed by Grünbaum, Haine, Horozov, and Iliev they exhaust all bispectral regular (i.e. a(n) 6= 0, c(n) 6= 0,∀n ∈ Z) ...

To develop a gene transformation method for Flammulina velutipes, we constructed a vector with hph gene under control of the trp1 gene promoter. The vector was integrated into protoplast derived from mycelia by the calcium-polyethylene glycol method, as it has not been reported for F. velutipes. Transformation efficiency was much improved when transformation was performed by the restriction enz...

The Davies transformation is a method to transform the steering vector of a uniform circular array to another vector with Vandermonde form. However, this transformation can be highly sensitive to perturbations of the underlying ideal array model. In this paper, we describe a method for deriving a more robust transformation using optimisation techniques. The effectiveness of the method is illust...
