Source retrieval is a part of a plagiarism discovery process, where only a selected set of candidate documents is retrieved from a large corpus of potential source documents and passed for detailed document comparison in order to highlight potential plagiarism. This paper describes a used methodology and the architecture of a source retrieval system, developed for PAN 2015 lab on uncovering pla...
یکی از پتانسیل های موجود در زمینه ی تولید و کاربرد الیاف الکتروریسی شده، تهیه نخ از نانوالیاف می باشدکه می توان از آنها بعنوان مواد پیشرفته در موارد مختلفی از قبیل منسوجات پزشکی و فیلتراسیون استفاده نمود. از پلیمرهای مختلفی می توان جهت تولید نخ نانوالیاف استفاده کرد. عمده تحقیقات پیشین بر روی پلیمر پلی اکریلو نیتریل بوده است، که بدون در نظر گرفتن عملیات تثبیت حرارتی از خصوصیات مکانیکی پایینی بر...
Object tracking is an important process for many applications in computer vision. This process must be implemented in a discrete manner because the images are available only at certain periods. A discrete integral sliding mode algorithm is proposed to control a stereo vision system and perform the aforementioned second task. The kinematic model of the structure is obtained using geometric algeb...
در این مطالعه با استفاده از سه نوع کوپلیمر پلی اکریلونیتریل (pan) حاوی کومونومرهای مختلف، نانوالیاف pan به روش الکتروریسی تولید شد. قطر متوسط نانوالیاف pan در محدوده nm560- 150 بود که قطر نانوالیاف با افزایش غلظت pan در محلول pan/dmf افزایش یافت. ساختار فیزیکی و شیمیایی به ترتیب به وسیله طیف پراش اشعه ایکس (xrd)، طیف سنجی مادون قرمز تبدیل فوریه (ft-ir) بررسی شد. علاوه بر این رفتار حرارتی نانوال...
Fuzzy measures generalize additive and probabilities. Their advantage with respect to ones is that they permit model interactions between objects. Mesiar introduced in 1999 k-order Pan-additive fuzzy k-maxitive ones. They are related the Möbius transform generalizations. In this paper we introduce some other transforms call ( M a x , + ) ? represent convenient way when use genetic algorithms me...
Graph neural networks (GNNs) extends the functionality of traditional to graph-structured data. Similar CNNs, an optimized design graph convolution and pooling is key success. Borrowing ideas from physics, we propose a path integral based (PAN) for classification regression tasks on graphs. Specifically, consider operation that involves every linking message sender receiver with learnable weigh...
The expedient field disposal of excess gun propellants on the ground is an integral part of live-fire training in many countries. However, burning excess propellant in the field will leave significant quantities of energetic residues and heavy metals in the environment. Compounds such as dinitrotoluene and nitroglycerin and metals such as lead will leach into the soil column, eventually migrati...
Abstract The class A pan method has been one of the most popular methods due to its simplicity, relatively low cost, and producing daily evapotranspiration estimates. Because of the large area occupied by a class A pan, alternative methods have been sought to estimate ETo inside greenhouses. With the objective of evaluating the performance of evaporation pan in estimating the water consumption...
in this article, we have focused one some basic and productive information about the properties of spectrum and singular values related to compact operators which are ideals in a c*-algebra of bounded operators. considering a two-sided connection between the family of symmetric gauge functions on sequence of singular values of compact operators and symmetric norms on finite dimensional ope...
this study was conducted to determine the effects of different water and nitrogen application levels on drip-irrigated tomato plants. the amount of water usage was based upon the pan evaporation from a screened (class “a”) evaporation pan. the treatments consisted of two irrigation intervals (i1= 5 days and i2= 10 days), three plant-pan coefficients (kcp1= 0.50; kcp2= 0.75 and kcp3= 1.00) and t...
