 Many efficient interior-point methods (IPMs) are based on the use of a self-concordant barrier function for the domain of the problem that has to be solved. Recently, a wide class of new barrier functions has been introduced in which the functions are not self-concordant, but despite this fact give rise to efficient IPMs. Here, we introduce the notion of locally self-concordant barrier functio...

this study aims to delve into the unobservable dimensions of deciding and acting in a pragmatically significant speech event. utilizing a discourse completion test questionnaire, it seeks to find out the structure and pragmatic functions that lie behind efl learners’ choice of specific wording while engaged in performing a recurrent speech act in iran i.e. compliments. to this aim, 30 efl learn...

our aim in this paper is to prove an analog of younis's theorem on the image under the jacobi transform of a class functions satisfying a generalized dini-lipschitz condition in the space $mathrm{l}_{(alpha,beta)}^{p}(mathbb{r}^{+})$, $(1< pleq 2)$. it is a version of titchmarsh's theorem on the description of the image under the fourier transform of a class of functions satisfying the dini-lip...

in this article the nonlinear mixed volterra-fredholm integral equations are investigated by means of the modied three-dimensional block-pulse functions (m3d-bfs). this method converts the nonlinear mixed volterra-fredholm integral equations into a nonlinear system of algebraic equations. the illustrative   examples are provided to demonstrate the applicability and simplicity of our   scheme.

a numerical method for solving variational problems is presented in this paper. the method is based upon hybrid of hartley functions approximations. the properties of hybrid functions which are the combinations of block-pulse functions and hartley functions are first presented. the operational matrix of integration is then utilized to reduce the variational problems to the solution of algebraic...

در این پایان نامه ابتدا در مورد توابع تک ارز خواص هندسی آنها وهمچنین رابطه ی این خواص هندسی با شرایط معادل خواص تحلیلی مطالعه می کنیم سپس با استفاده از خاصیت محاطی دیفرانسیلی ( کارهای miller و mocanu در این خصوص مهم هستند ) زیر کلاس جدیدی از توابع تک ارز تعریف می کنیم . سعی می شود در خصوص این کلاس که چندین پارامتر هم دارد شرایطی را روی پارامترها با اثبات قضایا و نتایج جالب تعیین کنیم کارهای این...

in this work, we obtain the fekete-szegö inequalities for the class $p_{sigma }left( lambda ,phi right) $ of bi-univalent functions. the results presented in this paper improve the recent work of prema and keerthi [11].

‎in the present paper‎, ‎by making use of the differential subordination and‎ ‎superordination results of miller and mocanu‎, ‎  ‎certain classes of admissible functions ‎are determined so that subordination as well as superordination implications‎ ‎of functions associated with an integral operator hold‎. ‎additionally‎, ‎differential sandwich-type result is obtained‎.

Which comes first—the lyrics or the music? Here we consider the lyrics-first approach to songwriting and seek to augment the process by developing a creativity-support tool which uses lyrics as a creative constraint for rhythm generation. We describe a novel algorithm for suggesting possible melodic rhythms to complement the accent structure of a given set of lyrics. The algorithm is composed o...
