Abstract —

In this paper, the implementation of a high quality integrated data reconstruction model and
algorithm has been proposed, especially for medical applications. Patients’ Information acquired at the sending end and reconstructed at the receiving end by using a technique that would be high quality for the signal reconstruction process. A method is proposed in which the
reconstruction of data like ECG, audio and other patients’ vital parameters that are acquired in the time-domain and operated in the frequency-domain. Further the data will be reconstructed in the time-domain from the frequency domain where high quality data is required. In this particular case, high quality ensures the distortion less and noiseless recovered baseband signal. This would usually require the application of Fast Fourier Transform (FFT) and Inverse Fast Fourier Transform (IFFT) return the data to the spatial domain. The simulation is performed using Matlab. The Composite baseband signal has been generated by developing a program as well as by acquiring to the workspace. The feature of the method is that it can achieve high-quality integrated data reconstruction and can be associated easily with spatial domain.

Abstract-

This paper presents the spectrogram effect of biomedical signal, especially for ECG. Simulation module developed for the spectrogram implementation. Spectrogram based on ECG signal and power spectral density together with off-line evaluation has been observed. ECG contains very important clinical information about the cardiac activities of heart. The features of small variations in ECG signal with time-varying morphological characteristics needs to be extracted by signal processing method because there are not visible of graphical ECG signal. Small variations of simulated normal and noise corrupted ECG signal have been extracted using spectrogram. The spectrogram found to be more precise over conventional FFT in finding the small abnormalities in ECG signal. These form time-frequency representations for processing time-varying signals. By using the presented method, it is ensure that high resolution time-varying spectrum estimation with no lag error can be produced. Other benefits of the method are the straightforward procedure for evaluating the statistics of the spectrum estimation.

Abstract–

In this paper, a new method has been proposed to eliminate the intersymbol interference (ISI) and interchannel interference (ICI) for discrete multitone/orthogonal frequency division multiplexing (DMT/OFDM) systems by considering Time to Live (TTL) of multipath channel fading, especially for wireless medical application. In this method, the existence time of the packet is considered as the maximum propagation time and when the packet is sent to the receiver, the down count of the TTL starts. The existence of the packet in a network depends on TTL in an Internet Protocol (IP) packet that tells a network router whether or not the packet has been in the network too long and should be discarded. The proposed structure prevents ICI with a preprocessing method that utilizes a particular time that is equal to the continuation time of the packet and removes ISI by canceling the replica at the receiver. The simulation results show that the proposed method reduces the BER/ISI better under mutipath fading environment than other existing system.

Abstract:
This paper presents the new laser ray cost effective touch screen technology is to create a touch screen that is easily operated by the users without training the touch screen can be portable and movable without display system. A touch screen technology has been developed which is used to operate a computer for opening all folder by only a single touch on the screen. This work is divided into two main sections. One is hardware section which consists of a personal computer, voltage divider circuit, LDR, and Laser light source. And the other is the program control unit. This program has been written with visual basic language. Laser light has been used as the light source and LDR has been use as sensor. In its inactive mode laser light falls directly on the LDR which intern produces low voltage (logic 0) and when some obstacles (egg, human finger or stick etc) are in front of the light source , no light or very small light falls on the LDR which then produces high voltage (logic 1). In other words, this circuit gives a Low voltage when the LDR is in the light and a high voltage when the LDR is in the shade. The voltage divider circuit gives an output voltage which changes with illumination. In this way, eight LDRs produced an 8 bit signal such as 10001111, 11001111 etc. The voltage across LDRs is directly connected to the printer port (10, 11, 12, 13and 15) of the CPU. Finally, it is found that the proposed technology is better than the other existing technique.

ABSTRACT:

This paper presents a new bandwidth estimation method for individual hop for high-speed, non-invasive, and faster convergence transmission in multiple medical data networks. Available Bandwidth Estimation Technique for individual Hops (ABETH) has been developed employing parameters like Hop (H), Capacity (C), Bandwidth (B), Available Bandwidth (AB) etc. Bandwidth estimation techniques, tools and methods are considered to develop the technique and it represents an effective combination of different other existing techniques aiming to exploit the positive aspects of them. More precisely, the technique which is implied in the method modifies and integrates the one recent tool SPRUCE which estimates available bandwidth and the IP layer capacity estimation formula which measures capacity. This technique provides a linear combination of capacity versus bandwidth which satisfies the link utilization demand.

ABSTRACT:

In this paper, the analysis of 2D signals, especially emergency biomedical images are performed using the wavelet tools of MATLAB, has been presented for medical application. In terms of 2D signal analysis, an image is taken and added with different four types of noise (Salt and Peeper, Speckle, Gaussian and Poisson). After that all of the noisy images are de-noised for further comparison with the statistical data of the original image. Later the decision is taken based on the impact of the noises, which noise is less harmful and from which noise the signal can be reconstructed mostly. The applications of wavelet in different sectors along with some practical usage are also discussed.

Abstract
In this paper, a high performance intelligent network, specifically the T-mobile division of German telecom which uses the IN-statistics tickets, has been investigated. A ticket is a set of binary data that contains the information generated when a call is set up between a calling party and a called party. These tickets are usually big in size, necessitating a convenient tool to interact with the huge amount of binary data. The task is to create a graphical interface that allows searching for specific tickets by parameters to be defined. This interface will be implemented by the Unix-based GUI (Graphical User Interface) such as XWindows.

Abstract— In this project, different de-noising methods have been considered to eliminate noise from the ECG signal. Different de-noising methods are introduced and analysed both theoretically and empirically. Simulated ideal ECG signal and noise corrupted ECG signal are offline evaluated using MATLAB. The analyses of existing methods have been compared based on different parameters. A significant decision has been extracted for noise cancellation from ECG signal because noise is considered to be eliminated. Here three types of method are used for de-noising like Notch filter, Sgolay filter and Wavelet. Among all existing methods, Sgolay filter has performed better than the other existing method.
