High frequency signal injection method for sensorless permanent magnet synchronous motor drives
The objective of this project is to design a high frequency signal injection
method for sensorless control of permanent magnet synchronous motor
(PMSM) drives. Generally, the PMSM drives control requires the appearance of speed and positon sensor…

Hiding health report in X-ray images to protect people privacy
X-rays images are a popular medical diagnoses method. These images are hard to read and to be understandable outside the medical community. However, the radiologist writes a report of the X-ray. This report can be understandable easily which, can…

Hidden Markov model technique for dynamic spectrum access
Dynamic spectrum access is a paradigm used to access the spectrum
dynamically. A hidden Markov model (HMM) is one in which you
observe a sequence of emissions, but do not know the sequence of states, the model went through to generate the…

HAR-MI method for multi-class imbalanced datasets
Research on multi-class imbalance from a number of researchers faces
obstacles in the form of poor data diversity and a large number of classifiers. The Hybrid Approach Redefinition-Multiclass Imbalance (HAR-MI) method is a Hybrid Ensembles method…

Handwriting identification using deep convolutional neural network method
Handwriting is a unique thing that produced differently for each person.
Handwriting has a characteristic that remain the same with single writer,
so a handwriting can be used as a variable in biometric systems. Each person have a different form of…

Hand gesture recognition using discrete wavelet transform and hidden Markov models
Gesture recognition based on computer-vision is an important part of
human-computer interaction. But it lacks in several points, that was image brightness, recognition time, and accuracy. Because of that goal of this research was to create a hand…
