RGB image watermarking on video frames using DWT

In this paper, we present a method of concealing an image, individually, on multiple frames of a video, using DWT Algorithm. Our aim, for this research, is to obtain a colored output image, as a watermark, on each frame of the video, and to do so, color component decomposition has been performed. Using DWT technique, we have successfully applied image watermarking on video frames, and have successfully obtained the improved PSNR and MSE values for the same.

Peltier module for refrigeration and heating using embedded system

Power consumption is one of the major issues in todays general life. But semiconductor is a great solution of this power consumption. If we success to use semiconductors in well manner then we can reduce power consumption. Peltier module is one of the best solutions for this. Air-conditioner carry 2000 or 3000 Watt power and cloth iron takes minimum 750 Watt power. But due to use of this Peltier module in our system it saves lots of power. We can say the cooler gives the temperature of air-conditioner in only approx. 200 Watt. And cloth iron takes only 50 Watt. The performance of these systems is evaluated in the research and also commercialization point of view, reliability of this device and life of this device is discussed in the paper. The output graph of cooling and heating according to time is shown in figures 8, 9, and 10. From these graph we can calculate the approximation of the performance and use this Peltier Module in our daily life to save power consumption.

Neural Network based indicative ECG classification

The Electrocardiogram (ECG) is undoubtedly the most used biological signal in the clinical world and it is a means for detection of several cardiac abnormalities. Pattern recognition, diagnostic classification of ECGs constitutes an interesting application of Artificial Neural Networks (ANNs). This paper illustrates the ability of a feed-forward back propagation using Neural Network for classify unknown ECG waveforms keen on one of the 4 discrete class. Out of the 4 classes, 3 of them correspond to abnormal ECG signals and 1 represents the healthy group. In addition, the Neural Network model developed has the option to categorize unknown ECG input signals as unclassified, since it represents an unknown pathology. Preliminary results are obtained using data from 4 different Physiobank ECG database.

Utilizing Solar Energy for Room Airconditioning System

In this research work, the working of solar air-conditioning system has been considered. This paper includes construction wise and parameter wise analysis of this complete system specially designed for Indian climate. The power consumption is a very major issue in India and the paper solves the problem of power consumption especially in the case of air-conditioning. Construction and working of air conditioning system has been explained and all the parameters related to the system have been considered. It will also have a small energy storage capacity. Variation in operating conditions of the system has been taken into account, while designing the system.

Improving quality of care during childbirth in primary health centres: a stepped-wedge cluster-randomised trial in India

Background Low/middle-income countries need a large-scale improvement in the quality of care (QoC) around the time of childbirth in order to reduce high maternal, fetal and neonatal mortality. However, there is a paucity of scalable models. Methods We conducted a stepped-wedge cluster-randomised trial in 15 primary health centres (PHC) of the state of Haryana in India to test the effectiveness of a multipronged quality management strategy comprising capacity building of providers, periodic assessments of the PHCs to identify quality gaps and undertaking improvement activities for closure of the gaps. The 21-month duration of the study was divided into seven periods (steps) of 3  months each. Starting from the second period, a set of randomly selected three PHCs (cluster) crossed over to the intervention arm for rest of the period of the study. The primary outcomes included the number of women approaching the PHCs for childbirth and 12 directly observed essential practices related to the childbirth. Outcomes were adjusted with random effect for cluster (PHC) and fixed effect for ‘months of intervention’. Results The intervention strategy led to increase in the number of women approaching PHCs for childbirth (26 vs 21 women per PHC-month, adjusted incidence rate ratio: 1.22; 95% CI 1.17 to 1.28). Of the 12 practices, 6 improved modestly, 2 remained near universal during both intervention and control periods, 3 did not change and 1 worsened. There was no evidence of change in mortality with a majority of deaths occurring either during referral transport or at the referral facilities. Conclusion A multipronged quality management strategy enhanced utilisation of services and modestly improved key practices around the time of childbirth in PHCs in India. Trial registration number CTRI/2016/05/006963.

An efficient multistage security system for user authentication

This paper proposes a multilayer security system which can be used in Home, Bank Lockers etc. to prevent thefts. Multilayer security provided by the combination of three securities which is based on the sequence of (I) RFID, (II) password and (III) Biometric consecutively. All the three modules are controlled through a microcontroller. The Proposed system is more efficient and reliable due to multistage security and may not be breached with the combination of all three stages.

Physical design implementation of 32-bit AMBA ASB APB module with improved performance

The Advanced Microcontroller Bus Architecture (AMBA) is used for system on chip representation for high-performance embedded microcontrollers. This paper reports on the physical design implementation of AMBA Advanced System Bus (ASB) and Advanced Peripheral Bus (APB) bridge module. Further, three bit ripple counter has been used to minimize the clock skew. For modeling and simulation ModelSim Version 10.3 is used and also test benches are designed for this purpose. Xilinx-ISE design suite is used to extract synthesis and design utilization summary, RTL Compiler for the Synthesis and Encounter Digital Implementation System is used for the physical design. It has been shown that efficient design of system clock leads to faster operation and better utilization of system resources.

Thermal insulation — A method to reduce heat load and electricity consumption — A case study of cold storages

The aim of this research is to find out how the electricity consumption can be reduced by reduction in the heat load. In furtherance of our aim, a cold storage has been taken for study and with the help of insulation in the cold storage; heat load has been reduced as it lowers the temperature. Several methods and materials have been discussed in this research and also provide the method of selection of particular material which will be better for insulation of cold storage. Different research papers mentioned in the reference applied few types of insulation method. This research paper, discusses about the technical aspects of selection of Thermal insulation like vapor pressure and vapor barrier for different cold storages.
