A dispersive homogenization model for composites and its RVE existence

designing and validating a textbook evaluation questionnaire for reading comprehension ii and exploring its relationship with achievement

در هر برنامه آموزشی، مهم ترین فاکتور موثر بر موفقیت دانش آموزان کتاب درسی است (مک دونو و شاو 2003). در حقیقت ، کتاب قلب آموزش زبان انگلیسی است( شلدن 1988). به دلیل اهمیت والای کتاب به عنوان عنصر ضروری کلاس های آموزش زبان ، کتب باید به دقت ارزیابی و انتخاب شده تا از هرگونه تاثیر منفی بر دانش آموزان جلوگیری شود( لیتز). این تحقیق با طراحی پرسش نامه ارزیابی کتاب که فرصت ارزیابی معتبر را به اساتید د...

Existence, uniqueness and homogenization for ferroelectric materials

We discuss existence, uniqueness, and homogenization results for a class of rate-independent, nonlinear ferroelectric models. We show that these models can be formulated in an energetic framework which is based on the elastic and the electric displacements as reversible variables and on interior, irreversible variables like the remanent polarization. The PDE system defining the model is restate...

Homogenization of Elastic Dielectric Composites

This paper presents the derivation of the homogenized equations for the macroscopic 5 response of elastic dielectric composites containing space charges (i.e., electric source terms) that 6 oscillate rapidly at the length scale of the microstructure. The derivation is carried out in the setting 7 of small deformations and moderate electric fields by means of a two-scale asymptotic analysis. 8 T...

Global Existence for Quasilinear Dispersive Equations

Global Existence for Quasilinear Dispersive Equations Ii

is invertible. Here we treat the case of inputs coming from free waves located far away from the origin. In order to simplify the presentation, we will only consider inputs that would have come from our first guess (that is |x|f is bounded in L). Hence, we now consider the case when at least one function f or g is supported away from the origin and assume that for all y1 in the support of f and...
