background: water is considered as the main source of life but water resources are limited and nonrenewable. different factors have caused groundwater to decrease. therefore, modeling and predicting groundwater level is of great importance. methods: monthly groundwater level data of about 20 years (october 1991 to february 2012) from the hamadan-bahar plain, west of iran were used based on peiz...

The locally linear embedding (LLE) algorithm is an unsupervised technique recently proposed for nonlinear dimensionality reduction. In this paper, we describe its supervised variant (SLLE). This is a conceptually new method, where class membership information is used to map overlapping high dimensional data into disjoint clusters in the embedded space. In experiments, we combined it with suppor...

This paper presents a novel space-vector based Generalized Discontinuous pulse width modulation (GDPWM) algorithm without angle estimation based on the concept of imaginary switching times. The conventional space vector pulse width modulation (CSVPWM) method with equal division of zero state vectors V0 and V7 is modified. A constantvariable μ and modulation phase angle δ ranging from 0 to 1 are...

<p>Optimal control of any variable speed wind turbine needs maximum power point tracking (MPPT) coupled to doubly fed induction generator (DFIG) for better generation. This paper offers a novel direct servo-speed turbine. latter is based on DFIG optimal hysteresis MPPT inverter current combined with space voltage modulation (SVM) technique, thus providing stable and continuous energy flow...

In this work we describe an application of the Support Vector Machine (SVM) classifier for the segmentation of wounds in color images. The SVM-based segmentation combines naturally a high dimensional space of image features into a single classification machine. Since particular choice of image features is crucial for the performance of SVM classifier, we investigate the efficiency of colorand t...

Inverters inherently have the property of controlling output frequency but the output voltage can’t be varied. Usually to vary output voltage we have to vary supply voltage which is not always possible for this reason PWM techniques gained momentum. Basic aim of PWM technique is to control output voltage and harmonic reduction. Pulse-width modulation (PWM), or pulseduration modulation (PDM), is...

In this project, we perform a text independent speaker identification experiment with a newly released data set, VoxCeleb (2017)[1], which consists of celebrity interview audio clips downloaded from Youtube. It’s a challenging data set in the sense that there are often multiple vocal sources in the same clip. A MFCC feature vector based Deep Neural Network (DNN) is used as our baseline. It is c...
