 Abstract

A high-gain DC-DC converter is essential in the generation of energy from non-conventional energy resources. Renewable energy applications like solar PV arrays and fuel cells produce insufficient output voltage. In practical applications, to meet the energy demands, the output voltage of the converter must be increased. The traditional boost converter is unsuitable for very high voltage gain because it provides high voltage gain at a high duty ratio. As a result, transient response problems and reverse recovery issues arise. Therefore, a dual output common ground quadratic boost converter with lower duty cycle has been designed. In this converter, the voltage stress on switching components is reduced as the converter has only one switch. Furthermore, the converter is more efficient and uses a constant input current, which is ideal for renewable energy applications. Moreover, this converter provides high voltage gain at low duty ratio and common ground structure reduces leakage current and electromagnetic interference. The analysis of the converter is carried out and the results are obtained using MATLAB/SIMULINK R2017a. Hardware implementation is done with PIC16F877A micro-controller and the switch is driven along with its driver TLP250H. A prototype of the converter is also implemented and tested to verify the analysis.

 Abstract

Sitting posture recognition can be used to evaluate the awareness of a person carrying out a task, such as working, and can aid in avoiding other health risks. To prevent the damage from dangerous sitting postures, an area sitting posture recognition system is desired with low power consumption and low computing overhead. The system ought to conjointly give sensible user experience with accuracy and privacy. This paper reports a unique posture recognition system on office chair which will completely different health-related sitting postures. The system uses force sensors, Analog to Digital Converter (ADC) board and a Machine Learning formula of a two-layer Artificial Neural Network(ANN) enforced on Arduino Atmega 2560 R3. The system achieves 97.78% accuracy with a floating-point evaluation and 97.43% accuracy with the 9-bit fixed-point implementation. The ADC management logic and therefore the ANN are constructed with a most propagation delay of 8.714ns. The dynamic power consumption is 7.35mW once the sampling rate is 5 Sample/second with the clock frequency of 5MHz.

 Abstract

Tampering and reproducing an image today is as easy as writing on walls. Image editing tools have made it easier to play around with any image. To protect the hard work of the original designer it is very important to protect rights of the originator and that is only possible if the original image is ascertained. To say the picture is original or a replica is as difficult as finding a needle in hay; even age-old watermarking techniques have failed in many cases. Protecting a digital image becomes even tougher as it is easy to manipulate. In this paper, a method for watermarking on Flat High Definition images has been proposed using DWT (Sym12).

 Abstract

There are numerous concepts and views regarding human posture and its significance. The posture means body position. It is the specific position of a person while sitting, standing, walking, lying etc. Good posture is the image of good personality. The posture changes from individual to individual. One posture which may be considered good for one individual may not hold true for another individual. Bad posture decreases our personality and it leads to many health problems. When the human beings are habitual of bad posture position then the people suffered from many postural deformities e.g. Kyphosis, lordosis, scoliosis, knock knee, bow legs etc. There are numbers of postural deformities which may either be acquired or may be congenital. Each type of postural deviation has its own peculiar causes and effects. Therefore, each postural deformity demands and requires proper attention and specific treatment for correcting the same. The present study aimed is the treatment and prevention of common postural deformities and its remedial measures.
