in this study which was carried out in 1974 in the province of isphahan a total of 23,273 individuals in the cities, and 18,671 individuals in the villages of the same area were studied. results show that the median age in rural area is 16 and in urban area is 18 years. the birth rate in rural is 27.7 per thousand were as the same rate in urban area is 40.2 per thousand. similarly the general f...

lipofibromatous hamartoma (lfh) is an extremely rare benign tumor, which is characterized by an excessive infiltration of the epineurium and perineurium by fibroadipose tissues. a 27-year-old woman was diagnosed with left carpal tunnel syndrome (cts) due to (lfh) of the median nerve. lfh was diagnosed by mri and sonography; the characteristic ultrasonographic feature of lfh showed a good correl...

background: we aimed to extract the histogram features for text analysis and, to classify the types of bio medical waste (bmw) for garbage disposal and management. methods: the given bmw was preprocessed by using the median filtering technique that efficiently reduced the noise in the image. after that, the histogram features of the filtered image were extracted with the help of proposed modifi...

conclusions we explain embryologic origin, differential diagnosis, other associated anomalies and its treatment by reviewing literature. introduction midline cleft of mandible, classified as tessier 30 clefts is extremely rare, with less than 100 reported cases in the latest studies. variations in severity and associated malformations have been reported before. case presentation in this report,...

in this paper we study finding the $(k,l)$-core problem on a tree which the vertices have positive or negative weights. let $t=(v,e)$ be a tree. the $(k,l)$-core of $t$ is a subtree with at most $k$ leaves and with a diameter of at most $l$ which the sum of the weighted distances from all vertices to this subtree is minimized. we show that, when the sum of the weights of vertices is negative, t...

In this paper, we introduce a new mesh filtering method: a mesh median filter. This is an application of the median filter to smoothen 3-D noisy shapes given by triangle meshes. An algorithm of the mesh median filter is realized by applying the median filter to face normals on triangle meshes and updating mesh vertex positions to make them fit to the filtered normals. As an advanced modificatio...

Ensemble clustering is a recently evolving research direction in cluster analysis and has found several different application domains. In this work the complex ensemble clustering problem is reduced to the well-known Euclidean median problem by clustering embedding in vector spaces. The Euclidean median problem is solved by the Weiszfeld algorithm and an inverse transformation maps the Euclidea...

پژوهشگران اخیراً پنل‌های چندلایه‌ی متشکل از الوارهای متقاطع چوبی (C‌L‌T) را به عنوان یکی مناسب‌ترین ماده‌های ساختمانی دارای کمترین اثرات منفی زیست محیطی معرفی کرده‌اند. در طرح سازه‌ی ترکیبی فولادی ـ ارائه شده پژوهش حاضر، قاب ساختمان نوع بوده و برای کف‌ها دیوارهای برشی سازه افقی قائم C‌L‌T استفاده است. جهت بررسی عملکرد سیستم ای پیشنهادی، یک ۶ طبقه با دو باربر جانبی شامل: الف) خمشی متوسط دیافراگم ...

این مقاله حاصل پژوهشی درباره قیمت‌گذاری و تبلیغ پویا است با استفاده از یک مدل کنترل بهینه، روشی برای تعیین تعداد بلیت فروش رویداد ورزشی یا تفریحی به­دست می­‌دهد تا سود برگزارکننده بیشینه شود؛ همچنین سعی شده حد ممکن هزینه پشتیبانی در این­گونه رخدادها نظیر غذا، نوشیدنی، کالاها، بیمه، امکان واگذاری رایگان سایر خدمات به خریداران نظر گرفته شود. روش، علاوه بر بلیت‌­ها (برنامه‌­ریزی ظرفیت)، قیمت پویای...
