ECG signals are often corrupted by 50 Hz noise, the frequency from power supply. So it becomes quite necessary to remove Power Line Interference (PLI) signal. The reference signal data was taken MIT-BIH database. Different filtering techniques comprising of Discrete Wavelet Transform (DWT), Normalized Least Mean Square (NLMS) filter, Finite Impulse Response (FIR) filter and Infinite (IIR) were used in this paper for denoising which PLI. Later, comparison made among methods, find best...
The most vital challenge in seismic signal processing is the attenuation of random noise data. Many methods are formulated to mitigate but fail retain high accuracy. In this article, a hybrid methodology based on optimal empirical wavelet transform (OEWT), energy kurtosis mean filtering (EKMF), and new thresholding (NWT) technique, namely, OEWT-EKMF-NWT, proposed suppress signals. OEWT-EKMF-NWT method, OEWT decomposes into several intrinsic mode functions (IMFs) using segmentation method....
It has been observed by many researchers that the protein coding regions of DNA exhibit a period-3 behavior due to codon structure. The property is not present outside regions, and can be exploited locate regions. For eukaryotes (cells with nucleus) this periodicity mostly within exons introns. Previously binary indicator sequence electron-ion interaction pseudo potentials (EIIP) used for identification In paper we complex provides strong spectral component compared EIIP sequence. We also...
With the advent of digitization every possible avenue, Automatic Speech and Emotion Recognition is a widely researched topic that subset Human Computer Interface (HCI) has range applications. machines taking over many menial jobs it become important for computer to understand us as we it. Features such MFCC, pitch amplitude are extracted from given sample run across existing growing database training samples. MFCC being used detected speaker utterance, while SVM distinguish emotion given. An...
Electroencephalogram (EEG) signals are mostly contaminated with ocular artifacts (OAs) due to eye movements and blinks. These make the EEG recordings difficult analyze diagnose neurological diseases. Therefore, in this work, we propose a hybrid framework that consists of two stages remove OAs from signals. A correlation-based variational mode decomposition (VMD) method first stage removes baseline wander noise. Then, an improved adaptive chirp (IACMD) continuous wavelet transform (CWT)...
In genomic research, identifying the exon regions in eukaryotes is most cumbersome task. This article introduces a new promising model-independent method based on short-time discrete Fourier transform (ST-DFT) and fine-tuned variational mode decomposition (FTVMD) for regions. The proposed uses N/3 periodicity property of eukaryotic genes to detect using ST-DFT. However, background noise present spectrum ST-DFT since sliding rectangular window produces spectral leakage. To overcome this,...
Generation of all maximal independent sets (MIS) is a NP-complete problem for general graphs. In this paper, using particular geometric property trapezoid graph, an efficient algorithm designed which enables to generate graph in time, where [mbar] and are respectively the number edges complement given generated sets. There no prior available solve finding MIS
We’re still in the middle of 4G revolution, that superfast mobile data service is its infancy both coverage and speed capabilities. Customers telecommunication demand more from their technology. To maintain such a powerful system, we require high wireless connectivity. The drawbacks technology led researchers developers to arise with advanced efficient technologies. 5G next generation networks will totally replace existing networks. This paper focuses on all preceding generations...
Rising traffic clog is an unpreventable condition in enormous and developing metropolitan zones all over India.An increased volume of vehicles not only increases the chances for them being involved accidents.According to a report published Times India, 146,133 people were killed road accidents India year 2016.Unfortunately, about 30% deaths are caused due delayed ambulance.Another data shows that more than 50% heart attack cases reach hospital late.Everybody detests clog, it continues...
Prior to applying the digital signal processing techniques for identification of protein coding regions, mapping DNA alphabet into numerical sequences is necessary. In this paper, performance existing analyzed at nucleotide level regions using tapered window based short-time discrete Fourier transform (ST-DFT) method applied GENSCAN test set. The results show better accuracy Voss, z-curve and tetrahedron technique as compared other when windows are used ST-DFT method.
Diagnosing cardiac conditions require careful examination of an electrocardiogram (ECG). However, a significant issue arises when capturing ECG due to interference from various noises. Noises like power line (PLI) and muscle artifact (MA) change the morphology, making it difficult interpret original signal. Our research proposes improved variational mode extraction (IVME) technique using Heap-based optimization (HBO) algorithm automatic wavelet interval-dependent thresholding (AWIT) method...
Modified Gabor-Wavelet Transform (MGWT) has been previously used for identification of protein coding regions. This method does not significantly suppress the non-coding regions which may result incorrect identification. To enhance discrimination between and DNA sequence, Signal Boosting Technique (SBT) is applied on projection coefficients are obtained by applying MGWT. The performance proposed with (MGWT-SBT) compared other existing methods such as MGWT, Short-Time Discrete Fourier...
