Interest in studies on fractional calculus and its applications has greatly increased recent years. Fractional-order analysis the potential to enhance dynamic structure of chaotic systems. This study presents implementation a lower-order electronic circuit using standard components for Sprott K system. To our knowledge, there are no realizations literature where value fractional-order parameter...
پرتاب کننده های جامی شکل یکی از انواع مهم مستهلک کننده ها می باشند و نقش استهلاک انرژی جریان در سرریز ها را به عهده دارند. در این پژوهش به بررسی خصوصیات هیدرولیکی جریان بر روی پرتابه جامی شکل با مدل عددی فلوئنت پرداخته شده است. در این تحقیق به منظور گسستهسازی محیط شبیهسازی از سه نوع شبکه محاسباتی سازمان یافته (درشت، متوسط و ریز) استفاده شد. به منظور شبیهسازی جریان از مدلهای آرام، k-ε (Sta...
Flow separation at water intake is the main cause of head loss and flow discharge reduction. As a result, study of shape and size of separation is very essential when designing an optimum water intake. Water intake is normally built with a 90 degree angle to the main channel flow direction. However, the flow structure in this type of water intake consists of large separation size along with ...
The purpose of this research is to evaluate the quality of wine in Khorramabad city as a major issue in public health and health management of citizens. To perform this research, data on the chemical element of 23 wells and fountains in Khorramabad County during the period of 2002 to 2013 were presented in the form of a series of elements: fluorine (F), calcium (Ca), magnesium (Mg), potassium (...
This paper presents a new similarity measure to be used for general tasks including supervised learning, which is represented by the K-nearest neighbor classifier (KNN). The proposed similarity measure is invariant to large differences in some dimensions in the feature space. The proposed metric is proved mathematically to be a metric. To test its viability for different applications, the KNN u...
