What: Our vision is to bring together three previously distinct disciplines [education, psychology and neuroscience] – to focus on a specific common problem: how to promote better learning. This will mean building a new scientific community and a new discipline, educational neuroscience. Why: We now understand better how learning organizes and reorganizes the brain, but there is very little res...

This paper presents short summary about commonly used filters in macroeconomics. We consider Hodrick-Prescott filter, Butterworth filter, Ideal Bandpass filter, Baxter-King filter and Christiano-Fitzgerald filter. 1 The filtering problem Given raw data, {xt}t=1, we are interested in isolating component of xt, denoted by {yt}t=1, with period of oscillation between pl and pu, where 2 ≤ pl < pu < ...

This paper presents a formula-based method for the design of IIR filters having more zeros than (nontrivial) poles. The filters are designed so that their square magnitude frequency responses are maximally-flat at ! = 0 and at ! = and are thereby generalizations of classical digital Butterworth filters. A main result of the paper is that, for a specified half-magnitude frequency and a specified...

A wide area of research has been done in the field of noise removal in Electrocardiogram signals.. Electrocardiograms (ECG) play an important role in diagnosis process and providing information regarding heart diseases. In this paper, we propose a new method for removing the baseline wander interferences, based on discrete wavelet transform and Butterworth/Chebyshev filtering. The ECG data is t...

Ai Hua FAN and Qiyu SUN Abstract Let N be the re nable function with Butterworth lter cos2N 2( cos2N 2 +sin2N 2) 1, and let sp( N) be the Sobolev exponent of N of order p (0 < p 1). It is proved in this note that there exists a constant 0 < r = rp < 1 such that ln(1 + rN) ln 2 sp( N) N ln 3 ln 2 ln(1 + 3 N) ln 2 ; (8N 1):

Nowadays, robust and secure watermarking algorithm and its optimization have been need of the hour. A watermarking algorithm is presented to achieve the copy right protection of the owner based on visual cryptography, histogram shape property and entropy. In this, both host image and watermark are preprocessed. Host image is preprocessed by using Butterworth filter, and watermark is with visual...
