In many applications of speech processing the noise reveals some specific features. Although the noise could be quite broadband, there are a limited number of dominant frequencies, which carry the most of its energy. This fact implies the usage of narrow-band notch filters that must be adaptive in order to track the changes in noise characteristics. In present contribution, a method and a system for noise suppression are developed. The method uses adaptive notch filters based on second-order Gray-Markel lattice structure. The main advantages of ....etc

The photoacoustic effect - production of sound from light - may be exploited for detection and localization of gas leaks on the surface of otherwise sealed components. The technique involves filling the test component with a photoactive tracer gas, and irradiating the component to produce photoacoustic sound from any leak site where a tracer gas cloud forms. This presentation describes experiments utilizing 10.6-micron radiation from a carbon-dioxide laser with sulfur hexafluoride as a tracer gas. Here, photoacoustic sounds from a laminar plume ....etc

Motivation for In Vivo Optical Imaging (Partial List)
• Safety — Non-ionizing radiation: photon energy is ~2 eV
• Physics — Molecular structure and composition of tissue
• Optics — High intrinsic contrast. E.g., absorption probes
 Oxy-hemoglobin & deoxy-hemoglobin
 Melanin
 Lipid
 Water
 DNA & RNA
• Physiology — Endogenous contrast for functional imaging
 Concentration of hemoglobin (angiogenesis)
 Oxygen saturation of hemoglobin (hyper-metabolism)
 Cell nuclei
 ....etc

An Inverter is simply an electronic device that converts low voltage DC battery power 230 volts AC (Alternating Current) electrical power. They are used in applications ranging from microwaves laptops to satellite systems X-Ray machines etc.

Most industrial applications require high frequency high voltage power supply. These increased power requirements have lead to significant development in inverted technology.


Significant improvements have been made to the traditional pulse width modulations (PWM) Inverters to make power distributio ....etc

Imaging technology has a rich history that began thousands of years ago. The reflection from a pool of still water or a shiny metal surface was arguably the first imaging method routinely used by mankind. With the advent of lenses, many other novel forms of optical imaging emerged, including telescopes and microscopes.

Using a lens, a pinhole camera, and a sensitized pewter plate, Ni?pce was the first person to permanently record an image. Optical photography and other forms of optical imaging have since become commonplace.

Of course, im ....etc

Schizophrenia affects one in a hundred Canadians at some point in their life. This disorder is characterized by auditory hallucinations, delusions, lack of motivation and thought disorder. Antipsychotic drugs improve some of these symptoms, but there is no cure and the cause of schizophrenia is still unknown. Current models suggest that a brain lesion in-utero, in conjunction with neurodegeneration, may result in the symptoms of the disease. These processes may result in abnormal brain function, manifested as changes in brain metabolism.

What is Spectroscopy?
 The study of how 'species' (i.e., atoms, molecules, solutions) react to light. Some studies depend on how much light an atom absorbs. The electromagnetic radiation absorbed, emitted or scattered by the molecule is analyzed. Typically, a beam of radiation from a source such as a laser is passed through a sample, and the radiation exiting the sample is measured. Some, like Raman, depend on a molecule's vibrations in reaction to the light.
