Large flexible aircraft are often accompanied by large deformations during flight leading to obvious geometric nonlinearities in response. Geometric nonlinear dynamic response simulations based on full-order models carry unbearable computing burden. Meanwhile, caused wings most cases and the deformation of fuselages is small. Analyzing whole as a structure will greatly increase analysis complex...

generally, an engineering design problem has multiple objective functions. some of these problems can be formulated as multiobjective geometric programming models. on the other hand,often in the real world, coefficients of the objective functions are not known precisely. coefficients may be interpreted as fuzzy numbers, which lead to a multiobjective geometric programming with fuzzy parameters....

homogeneity and uniformity of soil particles is a most potent factor which affects soil spectral signatures. geometric standard deviation of soil particles (?g) exhibits the homogeneity of soil components. this study presents the influence of ?g on spectral studying of soil geometric mean particle diameter as well as lime. the study was conducted in pol-e-dokhtar using the data set of lissiii-p...

in early islamic era, architecture in khorasan was followed the common features of early islamic architecture style; such as simplicity in construction and ornament. in the later periods, especially in seljuq dynasty, the application of brick, stucco, tiling and inscription had been used more in architectural ornament. then, in the short period under the khwarizmshahid dynasty in khorasan, two-...

AbstractWe assume that the reader is familiar with basic Riemannian geometry and we freely refer to [17] in particular [51] for a presentation particularly suited computations Ricci flow setting. Here establish notation introduce geometric framework our subsequent analysis of interaction between Einstein constraints flow.
