ELECTROCARDIOGRAM (ECG) SIGNAL PROCESSING ON FPGA FOR EMERGING HEALTHCARE APPLICATIONS

In this project an ECG signal processing module will be implemented in VHDL on FPGA platform. The digital filtering will be carried out with low pass FIR architecture. Filters shall filter the 50 Hz coupled noise and other high frequency noises. The filtered signal is subjected to Short Time Fourier transform by which lot of inferences can be made by medical experts. A recorded ECG signal will be used as test input to test the modules implemented on FPGA. The Modelsim Xilinx Edition and Xilinx Integrated Software Environment will be used simulation and synthesis respectively. The Xilinx Chipscope tool will be used to test the results, while the logic running on FPGA. The Xilinx Spartan 3 Family FPGA development board will be used this project

Design of Microstrip Antennas for Wideband Applications

Microstrip or patch antennas are getting to be progressively valuable on the grounds that they can be printed specifically onto a circuit board. They are broadly utilized as a part of flying machines, satellites, mobile, wireless application where size, weight, cost, ease of installation, aerodynamic profile are constraints, low profile like microstrip antennas may be needed. Hence design and development of cost effective and superior microstrip patch antenna has become an active research area. The size reduction and impedance bandwidth improvement lies in great importance in today’s life.This thesis presents design of microstrip antennas for wireless applications. Four antennas designed are presented in the following chapters. The first design is a compact dual band microstrip antenna which produces dual band characteristics. The second design is a compact wideband microstrip antenna that has wideband characteristics which have applications in health care,medical field like health monitoring and imaging in intensive health care units,pediatric units,emergency situation like heart beat rescue. The third one is the Design of circularly polarized microstrip patch antenna using a pair of inserted slits. The fourth one is the design of hexagonal shaped patch antenna using coplanar waveguide feed. The antennas designed above have better radiation characteristics with improved bandwidth

Marketing Mix Strategies of Retailing and Buyers Behavior towards FMCG-A Study in Bangalore

The purpose of the study is to examine the general shopping behavior includes such variables as days of the week, presence of a shopping list, period of shopping and shopping with a credit card. It also included variables like whether people thought themselves to be impulse purchasers and also if they thought themselves to be impulse purchasers. To investigate the relationship between the touching and cognitive processes on impulse buying among consumers. and also to evaluate the effects of various demographic segments of customers. This leads us to conclude that consumers most often have an irresistible urge to buy, suffer from emotional conflict, manage their moods and like to increase their pleasurable moods states while indulging in impulse purchases. It may be concluded that the number of members in the family does not have a significant impact on cognitive deliberation with respect to impulse buyin

Comparative Analysis of common Edge Detection Algorithms using Pre-processing Technique

Edge detection is the process of segmenting an image by detecting discontinuities in brightness. So far, several standard segmentation methods have been widely used for edge detection. However, due to inherent quality of images, these methods prove ineffective if they are applied without any preprocessing. In this paper, an image preprocessing approach has been adopted in order to get certain parameters that are useful to perform better edge detection with the standard edge detection methods. The proposed preprocessing approach involves median filtering to reduce the noise in image and then Edge Detection technique is carried out. And atlast Standard edge detection methods can be applied to the resultant preprocessing image and its Simulation results are show that our preprocessed approach when used with a standard edge detection method enhances its performance

COMPARATIVE FORMULATION, EVALUATION AND OPTIMIZATION OF IMIDAPRIL MOUTH DISSOLVING TABLETS USING DIFFERENT SYNTHETIC SUPERDISINTEGRATING AGENTS

Objective: The aim of this work was preparing once daily mouth disintegrating tablets to handle easily for adult hypertensive patients who have difficulty in swallowing. Methods: Imidapril mouth dissolving tablets (MDTs) were prepared by direct compression method using different concentrations of synthetic super disintegrants namely Sodium starch glycolate, Croscarmellose sodium & Kyron T-314. The prepared tablets were evaluated for weight variation, thickness, hardness, friability, content uniformity, disintegration time and In-vitro dissolution studies.Results: The micropolitics study indicates that all formulations were of acceptable to good flowability. Tablet hardness and friability indicated that the prepared formulations were having good mechanical strength. The most satisfactory formulation F5 containing Sodium starch glycolate showed minimum disintegration time of 19 s and released a maximum amount of drug in 30 min in phosphate buffer 6.8pH, by an appropriate combination of excipients. The optimized F5 formulation containing Sodium starch glycolate was found to be stable during stability studies conducted for 3 mo as per International Conference on Harmonization (ICH) guidelines.Conclusion: The present study conclusively proved that Imidapril MDTs could be successfully developed using various super disintegrants. The prepared tablets gave promising results with respect to the faster release of Imidapril. Further clinical studies are suggested to confirm the ability of the best-achieved system to avoid the first pass metabolism of Imidapril and improve patient compliance.Â
