This document discusses determining noise levels in noisy speech signals. It presents the following:
1) Amplitude modulation spectrogram (AMS) features are extracted from noisy speech segments and classified as noise-dominated or signal-dominated using Bayes' classifier.
2) The classified features are reconstructed using overlap-and-add to obtain a reconstructed speech segment.
3) The signal-to-noise ratio (SNR) is calculated between the reconstructed speech segment and the original noises, as well as between the clean speech signal and noisy speech segment.
This paper proposes a novel adaptive filter for removing salt and pepper noise from images using fuzzy logic. The filter has two stages: detection and filtering. In the detection stage, a 3x3 pixel window is used to identify noisy pixels. Pixels with maximum or minimum intensities are identified as salt or pepper noise. In the filtering stage, the detected noisy pixels are passed through merge scanning and histogram processing to remove noise while preserving image details. Simulation results on standard test images show the filter can remove up to 95% salt and pepper noise while maintaining high PSNR and processing speed.
1) The document discusses the transition from traditional data centers to cloud computing through three phases - classic data center, virtual data center, and cloud. It describes the components and characteristics of each phase.
2) Virtualization is a key concept in cloud computing that allows multiple operating systems to run simultaneously on physical machines. Virtual machines are logical files that act like physical machines.
3) Security is an important challenge in cloud computing. Virtual machines can be targets for theft so proper security measures like authentication, access control, and antivirus software are needed between physical and virtual machines.
This document summarizes a research paper on determining noise levels in noisy speech signals. It discusses extracting amplitude modulation spectrogram (AMS) features from noisy speech segments and classifying them as noise-dominated or signal-dominated using Bayes' classifier. The classified features are reconstructed using overlap-and-add to estimate the signal-to-noise ratio between the original clean speech and reconstructed speech, and between the original clean speech and noisy speech. The paper presents results on speech segments corrupted with different noises, showing SNR is reduced between the original clean and reconstructed speech compared to the original clean and noisy speech.
This document summarizes a research paper on desktop virtualization using Software as a Service (SaaS) architecture. It proposes a system called Yet Another Desktop Virtualization (YADV) that provides desktop virtualization more efficiently by optimizing network bandwidth usage and reducing application overhead at the client side. YADV uses the OpenStack cloud computing platform to virtualize desktop operating system instances in the data center and allow users to access applications and desktops through thin client devices. It customizes operating system disk images and implements application streaming to only deliver specific applications rather than the entire desktop interface to clients. Evaluation shows YADV provides better quality of service and more efficient resource allocation than traditional desktop virtualization methods.

In the filtering stage, the detected noisy pixels are passed through merge scanning and histogram processing to remove noise while preserving image details. Simulation results on standard test images show the filter can remove up to 95% salt and pepper noise while maintaining high PSNR and processing speed.

Electrically small antennas: The art of miniaturizationEditor IJARCET
We are living in the technological era, were we preferred to have the portable devices rather than unmovable devices. We are isolating our self rom the wires and we are becoming the habitual of wireless world what makes the device portable? I guess physical dimensions (mechanical) of that particular device, but along with this the electrical dimension is of the device is also of great importance. Reducing the physical dimension of the antenna would result in the small antenna but not electrically small antenna. We have different definition for the electrically small antenna but the one which is most appropriate is, where k is the wave number and is equal to and a is the radius of the imaginary sphere circumscribing the maximum dimension of the antenna. As the present day electronic devices progress to diminish in size, technocrats have become increasingly concentrated on electrically small antenna (ESA) designs to reduce the size of the antenna in the overall electronics system. Researchers in many fields, including RF and Microwave, biomedical technology and national intelligence, can benefit from electrically small antennas as long as the performance of the designed ESA meets the system requirement.

This document discusses and compares two techniques for image denoising using wavelet transforms: Dual-Tree Complex DWT and Double-Density Dual-Tree Complex DWT. Both techniques decompose an image corrupted by noise using filter banks, apply thresholding to the wavelet coefficients, and reconstruct the image. The Double-Density Dual-Tree Complex DWT yields better denoising results than the Dual-Tree Complex DWT as it produces more directional wavelets and is less sensitive to shifts and noise variance. Experimental results on test images demonstrate that the Double-Density method achieves higher peak signal-to-noise ratios, especially at higher noise levels.

The document concludes that grid density clustering is better than k-means clustering as it can handle noise and outliers, find arbitrary shaped clusters, and has lower time complexity.
