IDR-QR: Incremental Dimension Reduction Algorithm via QR Decomposition (Java)
IEE Transactions on Knowledge and Data Engineering, Vol. 17, No. 9,

Abstract:
Dimension reduction is a critical data preprocessing step for many database and data mining applications, such as efficient storage and retrieval of high-dimensional data. In the literature, a well-known dimension reduction algorithm is Linear Discriminant Analysis (LDA). The common aspect of previously proposed LDA-based algorithms is the use of Singular Value Decomposition (S ....etc

Abstract Test card for color TV is a widely used method to evaluate the quality of a TV set directly. We have made a test signal generator (which can also generate synchronizing (abbreviated to sync hereafter) signals) mainly based on microprocessor Z-80. Taking the advantage of microprocessor programming, combining with the technique of microprocessor, digital circuits and analogue devices, we use software as far as possible to generate signals directly or to simplify the controlling circuits. Those signals, such as composite sync signal, bla ....etc

Abstract

The paper deals with the use of wavelet transform for signal and image de-noising employing a selected method of thresholding of appropriate decomposition coefficients. The proposed technique is based upon the analysis of wavelet transform and it includes description of global modification of its values. The whole method is verified for simulated signals and applied for processing of biomedical signals representing EEG signals and MR images corrupted by additional random noise. ....etc

Abstract
This paper presents a sufficiently low bit rate Hi-Fi
audio coding technique with low computation designed
for transmitting real-time high-quality audio signal over
wireless channel. This technique applies wavelet packet
transform to decompose audio signal into subbands to
eliminate redundant data using spectral and temporal
masking properties. The encoded audio data is framed
with some critical field is protected by channel coding to
improve noise immunity when frames are transmitted
wirelessly. Experimental results s ....etc

This article describes about wavelet packet (WP) filterbank.Most effective means of improving the auditory receptive abilities of people with profound hearing loss is cochlear implants(CI).Current cochlear implants consist of a microphone, a speech processor, a transmitter, a receiver and an electrode array which is positioned inside the cochlea.For decomposintion of input audio signal into different frequency bands and delivering the most appropriate stimulation pattern to the electrodes,speech processors are used.The bandwidths of the frequen ....etc

Decomposition in Concurrent Design for Technical Complex Systems


1. Introduction
Concurrent engineering is defined as a systematic approach to the integrated, simultaneous design of technical systems, products and processes, including manufacturing technical support.
The approach of concurrent engineering considers all the elements, beginning from the design and including quality, cost, schedule and user requirements.

2. Case study
