کیفیت توان امروزه به عنوان مبحث مهمی در مهندسی قدرت تبدیل شده است. علت عمده ی اهمیت یافتن کیفیت توان، افزایش تجهیزات حساس مصرف کنندگان در ته خط می باشد ]1[. در شبکه های امروزی با توجه به وجود بارهای حساس و اهمیت عملکرد مناسب این تجهیرات، بررسی پدیده هایی موسوم به پدیده-های کیفیت توان که باعث ایجاد تغییرات در ولتاز شبکه می شوند و جلوگیری از بروز آن ها و هم چنین کاهش اثرات زیان بار آن ها در صورت ...

We consider the problem of classifying trajectories generated by dynamical systems. We investigate a model-based approach, the common approach in control engineering, and a data-driven approach based on Support Vector Machines, a popular method in the area of machine learning. The analysis points out connections between the two approaches and their relative merits.

support vector regression (svr) solves regression problems based on the concept of support vector machine (svm). in this paper, a new model of svr with probabilistic constraints is proposed that any of output data and bias are considered the random variables with uniform probability functions. using the new proposed method, the optimal hyperplane regression can be obtained by solving a quadrati...

Klinkenberg permeability is an important parameter in tight gas reservoirs. There are conventional methods for determining it, but these methods depend on core permeability. Cores are few in number, but well logs are usually accessible for all wells and provide continuous information. In this regard, regression methods have been used to achieve reliable relations between log readings and Klinke...

seismic facies analysis (sfa) aims to classify similar seismic traces based on amplitude, phase,frequency, and other seismic attributes. sfa has proven useful in interpreting seismic data, allowingsignificant information on subsurface geological structures to be extracted. while facies analysis hasbeen widely investigated through unsupervised-classification-based studies, there are few casesass...

this paper concentrates on a new procedure which experimentally recognises gears and bearings faults of a typical gearbox system using a least square support vector machine (lssvm). two wavelet selection criteria maximum energy to shannon entropy ratio and maximum relative wavelet energy are used and compared to select an appropriate wavelet for feature extraction. the fault diagnosis method co...
