آنتن های زیادی با سطح مقطع استوانه ای وجود دارند که در کنار یا روی آنها تعدادی عنصر تابنده با طول محدود وجود دارند. این ساختارهای تقریبا استوانه ای را می توان با روش s2ds(spectrum of two dimensional solutions) تحلیل نمود. به این ترتیب که با استفاده از تبدیل فوریه نسبت به محور استوانه (محور z )، مسئله الکترومغناطیس سه بعدی اینگونه آنتن ها را می توان بصورت عکس مسائل دو بعدی با تغییرات ها...
neuroplasticity is the brain's ability to reorganize itself by forming new neural connections throughout life. neuroplasticity allows the neurons in the brain to compensate injury and disease and to adjust their activities in response to new situations or to changes in their environment. at the other side, it is now well established that neuronal function is strongly influenced by both cen...
objectives: this study compared the effects of individual and group training on general health and stress of parents of children with autism spectrum disorders. methods: a sample of 75 parents of children referring to autistic children foundation (including 50 parents in two experimental groups and 25 parents in control group) was taken into account. sample parents were selected through accessi...
the degree kirchhoff index of a connected graph $g$ is defined as the sum of the terms $d_i,d_j,r_{ij}$ over all pairs of vertices, where $d_i$ is the degree of the $i$-th vertex, and $r_{ij}$ the resistance distance between the $i$-th and $j$-th vertex of $g$. bounds for the degree kirchhoff index of the line and para-line graphs are determined. the special case of regular grap...
A method based on eigenvalue computations is formulated for computing the Chrestenson spectrum of a discrete p-valued function. This technique is developed by considering an extension to the same approach of computation of the Walsh spectrum for a twovalued function and is then generalized to the p-valued case. Algebraic groups are formulated that correspond to Cayley color graphs based on the ...
We investigate the function bias – generalising words to objects with the same function – in typically developing (TD) children, children with Autism Spectrum Disorder (ASD) and children with other developmental disorders (DD). Across four trials, a novel object was named and its function was described and demonstrated. Children then selected the other referent from a shape match (same shape, d...
We show a converse of a theorem of Ein, Lazarsfeld, Smith, and Varolin on the relation between the jumping coefficients and the roots of the b-function (i.e. the BernsteinSato polynomial) under certain hypotheses without which the assertion does not hold. For an explicit calculation we prove a formula for the multiplier ideals of stratified locally conical divisors, generalizing a formula of Mu...
The analysis of the large volume of tandem mass spectrometry (MS/MS) proteomics data that is generated these days relies on automated algorithms that identify peptides from their mass spectra. An essential component of these algorithms is the scoring function used to evaluate the quality of peptide-spectrum matches (PSMs). In this paper, we present new approach to scoring of PSMs. We argue that...
A method based on eigenvalue computations is formulated for computing the Chrestenson spectrum of a discrete p-valued function. This technique is developed by rst considering an extension to the conventional approach to computing the Walsh spectrum for a binary-valued function which is then generalized to the p-valued case (where p > 2). Algebraic groups are formulated that correspond to Cayley...
www.chestpubs.org authors) showed that after IV administration of colistin methanesulfonate (CMS), the plasma concentration of colistin is apparently suboptimal. The adverb “apparently” is necessary because the values of the pharmacodynamic indices that best predict the effi cacy of (free) colistin have been determined in in vitro and animal studies, 2 , 3 but are not yet known for humans. The ...
