power transformers are important equipments in power systems. thus there is a large number of researches devoted of power transformers. however, there is still a demand for future investigations, especially in the field of diagnosis of transformer failures. in order to fulfill the demand, the first part reports a study case in which four main types of failures on the active part are investigate...
امروزه سیستمهای خبره سطح فن آوری یک کشور را تعیین می کنند. این سیستمهای متکی بر پایگاههای اطلاعاتی، اهمیت مهندسی اطلاعات را نشان می دهند. اتوماتیک کردن صنایع، با توجه به وابستگی اتوماسیون با سیستمهای خبره اهمیت این سیستم ها را در رشد اقتصادی و فنی یک کشور روشن می سازد. موتورهای الکتریکی بعنوان محرک مکانیکی، در اکثر صنایع کاربرد دارند. بررسی عملکرد و گزارش وضعیت آنها از طرف مرکز کنترل و نظارت ، ...
abstract biometric access control is an automatic system that intelligently provides the access of special actions to predefined individuals. it may use one or more unique features of humans, like fingerprint, iris, gesture, 2d and 3d face images. 2d face image is one of the important features with useful and reliable information for recognition of individuals and systems based on this ...
fuzzy rule-based classification system (frbcs) is a popular machine learning technique for classification purposes. one of the major issues when applying it on imbalanced data sets is its biased to the majority class, such that, it performs poorly in respect to the minority class. however many cases the minority classes are more important than the majority ones. in this paper, we have extended ...
until now many studies have been done over recent decades throughout the world to show the right age to start english. in iran, research is still at an early stage in terms of evaluating teachers’ beliefs about teaching children english. the problem of at what age to start teaching english and how to teach english to elementary school children has not been solved neither in this country nor els...
this paper considers the automatic design of fuzzy rule-basedclassification systems based on labeled data. the classification performance andinterpretability are of major importance in these systems. in this paper, weutilize the distribution of training patterns in decision subspace of each fuzzyrule to improve its initially assigned certainty grade (i.e. rule weight). ourapproach uses a punish...
abstract nowadays, the science of decision making has been paid to more attention due to the complexity of the problems of suppliers selection. as known, one of the efficient tools in economic and human resources development is the extension of communication networks in developing countries. so, the proper selection of suppliers of tc equipments is of concern very much. in this study, a ...
application of ict in health (ehealth) has become an integral part of modern healthcare systems. electronic health information management has proven useful in improving quality of health care, reducing costs and facilitating health research. however, the increasing complexity of healthcare and the growing demand for high quality healthcare delivery has created a need for ehealth systems with t...
pluronic based nano-particulate systems are innovative platforms for delivery of anti-cancer agents. these systems due to their pharmacological properties and suitable physicochemical characteristics are great opportunity for development cancer therapeutics. this mini-review tries to provide a more detailed overview on the currently available pluronic based drug delivery systems. in the section...
چکیده در این پایاننامه ابتدا فضاهای متریک فازی را به صورت مشاهدهگرایانه بررسی میکنیم. فضاهای متریک فازی و توپولوژی تولید شده توسط این متریک معرفی شدهاند. سپس بر اساس فضاهایی که در فصل اول معرفی شدهاند آشوب توپولوژیکی، مینیمالیتی و مجموعههای متقاطع در شیوههای مختلف بررسی شده- اند. در فصل سوم مفهوم مجموعههای جاذب فازی به عنوان یک مفهوم پایهای در سیستمهای نیم-دینامیکی نسبی، تعریف شده است. ...
