A Weak SNR Signal Extraction Method for Near-Bit Attitude Parameters Based on DWT
نویسندگان
چکیده
In practice, the near-bit signals are usually accompanied by noises generated drilling tool vibration and high-speed rotary. This study introduces discrete wavelet transform to a well area presents new weal signal extraction algorithm, which can eliminate rotary effectively obtain useful gravity attitude based on through hard threshold method. The effectiveness usefulness of our method verified via Matlab simulation actual data.

Dwt - Based Feature Extraction from ecg Signal
Electrocardiogram is used to measure the rate and regularity of heartbeats to detect any irregularity to the heart. An ECG translates the heart electrical activity into wave-line on paper or screen. For the feature extraction and classification task we will be using discrete wavelet transform (DWT) as wavelet transform is a two-dimensional timescale processing method, so it is suitable for the ...
متن کاملA New Hybrid Method for Colored Image Steganography Based On DWT
Data transmission security has become an extremely important field of research. Steganography is an art of hiding information in image, audio and video files in a way that would meet the security requirements in the form of overt or covert. In this study, we propose a new hybrid steganography technique for color images that hide secret messages in the frequency domain of a cover image's blu...

Background: Since tumors located in thorax region of body mainly move due to respiration, in the modern radiotherapy, there have been many attempts such as; external markers, strain gage and spirometer represent for monitoring patients’ breathing signal. With the advent of fluoroscopy technique, indirect methods were proposed as an alternative approach to extract patients’ breathing signals...
متن کاملModified DWT for Feature Extraction of Bear Failure Vibration Signal
In this paper, bear fault is automatically diagnosed by using pattern recognition. To improve the resolution of lower frequency part, we introduce scale factors to discrete wavelet composition (DWT). The modified DWT combined with high order cumulates are used for vibration signal feature extraction. Besides we use principle component analysis to reduce dimension of the feature data. This featu...
