esl/efl books play a crucial role in shaping language learners worldview of gender roles in society. the present study investigated the status of sexism in two sets of efl textbooks, one developed by non-native iranian authors (ili series) and the other by native authors (top notch series). first, two books from each series was selected randomly. then, a quantitative analysis was carried out wi...
let $k$ be a field of characteristic$p>0$, $k[[x]]$, the ring of formal power series over $ k$,$k((x))$, the quotient field of $ k[[x]]$, and $ k(x)$ the fieldof rational functions over $k$. we shall give somecharacterizations of an algebraic function $fin k((x))$ over $k$.let $l$ be a field of characteristic zero. the power series $finl[[x]]$ is called differentially algebraic, if it satisfies...
چکیده تحقیق حاضر بر آن است تا وضعیت ارائه لغات را درنمونه ای از کتابهای آموزش زبان انگلیسی در ایران بررسی نماید. به همین منظور، چهار سری از کتابهای عمومی آموزش زبان انگلیسی، (interchange series, top notch series, american english files series, and efl textbooks taught in high and pre-university schools in iran ) که مشتمل بر 28 جلد کتاب در سطوح مختلف می شدند بر مبنای مدل (2001) nationمورد بررسی...
in this paper, we propose a new residual analysis method using fourier series transform into fuzzy time series model for improving the forecasting performance. this hybrid model takes advantage of the high predictable power of fuzzy time series model and fourier series transform to fit the estimated residuals into frequency spectra, select the low-frequency terms, filter out high-frequency term...
the aim of this thesis is an approach for assessing insurer’s solvency for iranian insurance companies. we use of economic data with both time series and cross-sectional variation, thus by using the panel data model will survey the insurer solvency.

این پایان نامه براساس مقاله ای تحت عنوان "discontinuous derivations from algebras of power series" تهیه شده که توسط dales و bade درسال 1989 ارائه شده است . فرض کنیم a جبرباناخ جابجائی باشد. درسالهای اخیر تعدادی از مقاله ها مسئله دادن شرایط لازم وکافی روی a برای اینکه همه مشتقات از a بداخل هر -a مدول باناخ بطور خودکار پیوسته باشند را مطالعه کرده اند. برای مثال، فرض کنیم a جبرباناخ جدائی پذیر جاب...
growing demands and requires of high data rate systems cause significant increase of high frequency systems for wideband communication applications. as mixers are one of the main blocks of each receivers and its performance has great impact on receiver’s performance; in this thesis, a new solution for ku-band (12-18 ghz) mixer design in tsmc 0.18 µm is presented. this mixer has high linearity a...
efl/esl textbooks have been regarded as essential language teaching materials with which the learners spend about 70 up to 90 percent of their class time. the important role they play and their vast use make them not only influential in learning the language but also in shaping values and attitudes. put it another way, textbooks socialize learners using their contents (i.e. texts, illustrations...
assume ? ? l2(rd) has fourier transform continuous at the origin, with ˆ ?(0) = 1, and thatcan be represented by an affine series f = j>0 k?zd c j,k?j,k for some coefficients satisfying c 1(2) = j>0 k?zd |c j,k|2 1/2 <?. here ?j,k(x) = |deta j |1/2?(a jx ?k) and the dilation matrices a j expand, for example a j = 2j i. the result improves an observation by daubechies that t...
