Abstract In this paper, we investigate the problem of uniqueness transcendental meromorphic functions sharing three values with their derivatives in an arbitrary small angular domain including a singular direction. The obtained results extend corresponding from Gundersen, Mues–Steinmetz, Zheng, Li–Liu–Yi, and Chen.

SUMMARY We implemented and compared the implicit Euler time-stepping approach, inverse Fourier transform-based approach Rational Arnoldi method for simulating 3-D transient electromagnetic data. utilize finite-element with unstructured tetrahedral meshes spatial discretization supporting irregular survey geometries anisotropic material parameters. Both, switch-on switch-off current waveforms, c...

reflection seismic data consist of primary reflections, coherent and incoherent noises. one of the objectives of seismic data processing is to enhance the quality of the real signals by attenuating different kinds of noises. multiples constitute one of the most troublesome forms of coherent noises in exploration seismology. multiple reflections often destructively interfere with the desired pri...

In this paper, transfinite element method is used to analyze the two dimensional thermoelasticity problems. A comparison is made between the thermoelastic analysis results of the classical theory and theories with one or two relaxation times (i.e. L-S and G-L theories), for the half space problem. Governing equations are transformed to Laplace domain and then, node variables are calculated by t...

The genomic and cDNA clones encoding cellobiohydrolase II (CBHII) have been isolated and sequenced from a native Iranian isolate of Trichoderma parceramosum, a high cellulolytic enzymes producer isolate. This represents the first report of cbhII gene from this organism. Comparison of genomic and cDNA sequences indicates this gene contains three short introns and also an open reading frame codin...
