Switching Power Suppliers Noise Reduction in Ultrasound Doppler Fluid Measurements

“The Dynamics of Customers Switching Suppliers in Deregulated Power Markets”

As the possibility of effective competition is thought to arise in industries that were formerly characterized as natural monopolies, pressure by some customers and /or potential entrants is brought to bear on political and regulatory institutions to deregulate economically certain aspects of these industries, and to allow market pressures to substitute for regulatory oversight as a means of re...

Noise Bounds in Multicarrier mmWave Doppler Measurements

More and more research groups are working on experimental research of millimeter wave (mmWave) wireless communications. Up to now, most mmWave measurements have been carried out in static scenarios. However, as the Doppler effect scales linearly with the carrier frequency, mmWave multicarrier transmission is prone to intercarrier interference caused by Doppler shifts. Today, mmWave radio freque...

Speckle Noise Reduction in Medical Ultrasound Images

Speckle Noise Reduction in Ultrasound Images

Ultrasound imaging is a widely used medical imaging modality because it is safe, allows real-time visualization of moving structures, and is relatively inexpensive. But the major issue with ultrasound images is the presence of speckle noise, which is an inherent limitation of ultrasound images. Various filters are used to reduce the speckle noise and to enhance the quality of the image. This wo...
