در این پایان نامه، کنترل نرو-فازی در پرنده هدایت پذیر از دور (پهپاد) استفاده شده است ابتدا در روش پیشنهادی اول، کنترل کننده نرو-فازی توسط مجموعه اطلاعات یک کنترل کننده pid به صورت off-line آموزش دیده است و در روش دوم یک کنترل کننده نرو-فازی on-line مبتنی بر شناسایی سیستم توسط شبکه عصبی rbf پیشنهاد شده است. سپس کاربرد این کنترل کننده در پهپاد بررسی شده است و مقایسه ای ما بین کنترل کننده های معمو...
In recent years, with the advancement of positioning systems, access to a large amount of movement data is provided. Among the methods of discovering knowledge from this type of data is to measure the similarity of trajectories resulting from the movement of objects. Similarity measurement has also been used in other data mining methods such as classification and clustering and is currently, an...
We propose a novel similarity measure, called the correntropy coefficient, sensitive to higher order moments of the signal statistics based on a similarity function called the cross-correntopy. Cross-correntropy nonlinearly maps the original time series into a high-dimensional reproducing kernel Hilbert space (RKHS). The correntropy coefficient computes the cosine of the angle between the trans...
Improving cooking and eating quality of rice is one of the important objectives of many breeding programs. The study of genetic diversity in specific regions of rice genome using molecular markers is an important index that can be used for the application of marker assisted selection (MAS) in rice breeding programs. In this study, 48 rice genotypes were grouped using 7 microsatellite (SSR) mark...
abstract the first purpose of this study was to investigate the effect of consciousness-raising (c-r) activities on learning grammatical structures (simple present tense in this case) by iranian guidance school efl learners. the second one was to investigate the effect of gender on learning the simple present tense through c-r activities and tasks. finally, this study aimed to investigate the ...
in order to investigate biodiversity and production of cultivated medicinal plants in agroecosystems of qazvin province, a study was conducted during year of 2011. interviews were carried out with farmers by using semi-structured questionnaire to obtain information regarding to biodiversity and medicinal plants production systems in main regions under cultivation of medicinal plants including f...
PURPOSE We evaluated the performance of organ contour propagation from a planning computed tomography to cone-beam computed tomography with deformable image registration by comparing contours to manual contouring. MATERIALS AND METHODS Sixteen patients were retrospectively identified based on showing considerable physical change throughout the course of treatment. Multiple organs in the 3 reg...
We investigate the Nonlinear Schrödinger Equation with a timedependent nonlinear coefficient. By means of Painlevé analysis we establish the integrability of a particular case, when the nonlinear coefficient decays with t. The corresponding soliton solution is shown to be of the self-similar kind. We discuss implications of the result to the dynamics of attractive Bose-Einstein condensates unde...
Haloxylon salicornicum (Moq.) Bunge ex Boiss is a shrub that grows in large parts of the central regions of Iran. Due to the high adaptability of this species to the severe environmental conditions and its importance in the stabilization of sand dunes, Dust control and medicinal functions recognition of its genetic diversity and the selection of superior genotypes is very important. A set of ...
