ABSTRACT Current Method of speech enhancement has been developed with adaptive filtering approach. The removal of unwanted signal i.e. noise from speech signals have applications ranging from cellular communications to front ends for speech recognition system. This paper describes proficient algorithm for removal of noise from speech. An optimal evaluation of LMS based adaptive filtering has been implemented for the observed noisy speech. This Algorithm is basic adaptive algorithm. This Adaptive

As a result of the calculations made above the concentration of the pure ASA in the 10.0mL of NaOH in mg/mL, based on the Beer’s Law plot found in figure 1.0 was 0.0978mg/mL. Presumably, the mass (in mg) of pure ASA based on the two consecutive dilutions was approximately 97.8 mg this value is unsuccessfully proven to match the associated theoretical value due to the overall percent yield, which will be discussed further. Also, according to the same calculations made in calculation #1, the calculated

former approach, such as the High-Frequency Signal Injection (HFSI) [4-7], is suitable for low-speed running or standstill condition of PMSM. The latter approach has Back Electromotive Force (BEMF), Sliding Mode Observer (SMO) [8-9] and Extended Kalman Filter (EKF) [10-12] which are suitable for medium or high-speed running condition of PMSM. The EKF is basically a full-order stochastic observer for the recursive optimum state estimation of a nonlinear dynamic system in real time by using signals that

If it is true that we are a species that is destined to continue our path of unrestrained growth then it follows that w must be the first to reach such a place. Most non conspiracy solutions to the Fermi Paradox lie on similar veins to The Great Filter saying that their is a point that technological advances can reach before a society collapses on itself and that is why we have seen no evidence of other alien life. But Kurzweil makes bold claims that seem to disagree with this theory. The possibility

For this experiment, my group had several leaves of spinach and hole punched 40 disks out of the spinach leaf. In order to avoid any bias results, we made sure to avoid hole punching any veins in the spinach. After that we filled 4 cups each with 100 milliliters of carbon water. Each cup would have a different amount of salinity, the first cup would be the control group which would have no salt in it. The second cup would have ¼ of a teaspoon of salt in it, the third cup would have ½ of a teaspoon

potassium hydroxide into the 250mL beaker with the aluminum pieces as it’s on the hot plate. Thirdly, set up the aspirator and connect it to the apparatus; then apply a damp filter paper to the büchner funnel when the solution is completely done mixing with the aluminum pieces. Turn on the vacuum and pour the solution through the filter. Once, that is complete, move the filtrate to a clean 250 mL beaker and clean the flask using 10 mL of distilled water and emerge the clean flask with the filtrate. Add

various types of noises. It may cause due to some disturbances or may be impulse noise. To suppress noise and improve the image performances we use image processing schemes. In this paper they uses Kalman filter to remove the impulse noise. The Kalman filter is digital signal processing based filter. It estimates three states past, present and future of a system.[10] To remove noise from video sequences they utilize both temporal and spatial information. In the temporal domain, by collecting neighbouring

DESIGN OF LOW PASS FIR FILTER THROUGH PARTICLE SWARM OPTIMIZATION Abstract: In the common case, the impulse response is finite because there is no feedback in the FIR. A lack of feedback guarantees that the impulse response will be finite. Therefore, the term "finite impulse response" is nearly synonymous with "no feedback". However, if feedback is employed yet the impulse response is finite, the filter still is a FIR. In this paper FIR filter design through particle swarm optimization. Key

phenetidine to make Dulcin (Scheme 1 equation 2). Scheme 1: Steps in Dulcin Synthesis. The apparatus used was the vacuum filtration, which is faster than the gravity filtration and can only be used with a Büchner funnel. When using the Büchner funnel, a filter paper needs to be inside of the funnel, as well as, a rubber stopper placed on the funnel to guarantee a good seal. After the experiment was completed, a pure sample of Dulcin was obtained because the exact melting point was determined to be 171.5-172
