The paper presents the task of auto-detecting the tiny nodules, which will help to get more information of pulmonary tuberculosis (TB). We apply two image processing technique into lung tissue information recognition. (1) A repetitive smoothing-sharpening technique is proposed and its impact is assessed to beneficially enhance X-ray lung images. (2) The… (More)
A pseudo random number generator (PRNG), also known as a deterministic random bit generator(DRBG), is an algorithm for generating a sequence of random numbers. This paper presents an implementation of pseudo random number generator. The design has been specified in VHDL and is implemented on altera FPGA device. It is based on the Residue Number System… (More)
Speech processing is the study of speech signals, and the methods used to process them. In application such as speech coding, speech synthesis, speech recognition and speaker recognition technology, speech processing is employed. In speech classification, the computation of prosody effects from speech signals plays a major role. In emotional speech signals… (More)
This paper proposes the implementation of an Enhanced Partial EZW algorithm that is based on the probability of significant coefficients within each bit plane on the lung X-ray image and thereby improves the performance. The main purpose of this paper is to analyse the impact and quality of wavelet filter for EZW and also to look into the effect of the… (More)
Lock-in amplifiers are used to process the analog signals even in the presence of noise sources of greater amplitude. In the present study, an attempt is made to design a C8051F060 microcontroller based lock-in amplifier. The microcontroller contains all the on-chip features to design a single-chip lock-in amplifier. The reference signal for lock-in… (More)
Osteoporosis is a condition where bones are fragile with a poor bone mineral density. This increases the risk of fracture especially of the hip, vertebrae, and wrist. These fractures are usually termed "fragility fractures." In this article, we aim to provide a broad overview of osteoporosis-investigation, management, and prevention.
This paper presents the design and implementation of an integrated fuzzy logic controller (IFLC) for a high-speed permanent magnet DC (PMDC) motor speed control system. The proposed strategy is intended to improve the performance of the conventional controller by use of IFLC. The system is studied for step input with and without load (magnetic) conditions… (More)
