abstract: the present thesis includes ; one preface and 11speeches , that each speech considered in different researches . the prefact part , studied grammer back ground , the first speech considered a brief description about grammatical credits . the second speech considered the different typs of sentences , from structure and meaning points of view . the third speech considered the verb es...
This paper concern the optimization of a multilayered green wall structure including substrate and foliage in order to reduce as much possible backward noise reflection forward transmission from wall. Each component involved is fully characterized experimentally get its transfer matrix. Simulation demonstrated that layer superimposed doesn't affect losses but contributes greatly increase return...
In this work, the synthesis of porous structure of cadmium oxide with multilayered sheet-like morphology in nano-meter size using adipic acid as soft template by solvothermal/thermal decomposition process is reported. Chemical analyses exhibited that the formation of porous sheet-like structure is originated from bidentate coordination mode of adipate units to Cd-center. It was found that the c...
As a type of writing originating in postmodernism, metafiction by breaking fictional frameworks and distorting boundaries of imagination and reality tries to reveal the artificial nature of reality and its constructedness in relation to the dominant power discourses. Thus, every playful chaos in the postmodern novel form stems from the depths of critical thinking in postmodernist skepticism abo...
(Ti, Al)N/MoN and CrN/MoN multilayered films were synthesized on Si (100) surface by multi-cathodic arc ion plating system with various bilayer periods. The elemental composition and depth profiling of the films were investigated by Rutherford backscattering spectroscopy (RBS) using 2.42 and 1.52 MeV Li2+ ion beams and different incident angles (0°, 15°, 37°, and 53°). The microstructures of (T...
A denoising unit based on wavelet multiresolution analysis is added ahead of the multilayered perceptron. The cost function used in neural network learning is also applied as the denoising criterion and hence denoising itself is treated as a part of the integrated model. By introducing continuously derivable generalized soft thresholding function and infinite thresholds, a gradient based learni...
