 Abstract

Wireless charging has become increasingly popular for electric vehicles (EVs) in recent years. However, possible device damage may happen because of the sharp variations of inverter output current and the ZVS angle due to the alignment variation between resonant coils especially while charging. To design a protection strategy, the characters of the inverter output current and phase angle are analyzed when the wireless charging EV leaves. The protection strategy is composed of the insufficient angle protection, overcurrent protection, and the excessive angle protection. A detection circuit is designed to measure the variation of inverter output current and phase angle. A wireless charging EV prototype is established to validate the proposed methods. The experimental results show that the designed detection circuit and protection strategy can catch the abnormal working state of the system when the wireless charged EV leaves and take measures immediately to protect the main circuit of the system from device damages. Wireless power Transfer (WPT) is nowadays visible to us in many different areas of technology and in many different forms and types. The technological areas vary from the crucial biomedical technology to commercial products such as wireless electric vehicle, wireless charging units and many more. Wireless transmission is useful in cases where instantaneous or continuous energy transfer is needed but interconnecting wires are inconvenient, hazardous, or impossible. The wireless energy transfer gets unique in its area of technology because of its efficiency which is the most important parameter under consideration. This makes the wireless energy transfer different from other information transfer methods. Wireless power systems for near field energy transfer, are typically classified as either inductive or resonant. The wireless power transfer surpassing efficiency is the optimum technique to transfer the power wirelessly and power up the low power devices such as Mobile phones, small fans, and any microcontroller unit

Abstract: Sanitation and Hygiene is most important after pandemic in the school. The obstacles to improving the sanitation problem in rural India include poverty, cultural prejudices, lack of awareness, and a shortage of running water, among others. Sixty-five percent of the rural population in India either practices open defecation or has inadequate access to toilet facilities. Nearly half of Indians defecate into the environment, which pollutes water and leads to the number one cause of diarrhea-associated deaths in children. More than 140,000 children under the age of five die every year from diarrhea caused by unsafe water and poor sanitation in India. Poor sanitation is linked to transmission of diseases such as cholera, diarrhoea, dysentery, hepatitis A, typhoid and polio and exacerbates stunting. Poor sanitation reduces human well-being, social and economic development due to impacts such as anxiety, risk of sexual assault, and lost educational opportunities. In this paper researcher Explained about Sanitation and Hygiene polices and theoretical expositions ,schemes all over India. Each scheme is launched to provide benefits to the individual in certain areas of their life.

 Abstract

In a grid-connected solar system, a comparison of the Unified Power Flow Controller (UPFC) and Distributed Power Flow Controller (DPFC) is made. The main model is a grid-connected solar generation system with a boost converter and voltage source inverter (VSI). The grid side system must be meticulously monitored and managed due to power quality issues such as power oscillations, harmonic distortions, voltage sags, and swells. The use of reactive devices such as a shunt/series reactor and a shunt/series capacitor is one technique to alleviate these power quality issues. The downside of using these reactive elements is the occurrence of sub-synchronous resonance. So to overcome the sub synchronous resonance we are connecting the UPFC and DPFC to the grid connected photo voltaic cell and analyzed the best performance among them.

 Abstract

India's higher education system is the third largest in the world. Indian higher education system has expanded at a fast pace by adding nearly 20,000 colleges and more than 8 million students in a decade from 2000-01 to 2010-11. As the number of college and students is increasing simultaneously students have plenty of options to select the college. Thus, different factors including personal, external and social influences the choice of the students to select a particular college. India has the third largest higher education system in the world in terms of enrolments, after China and the US. India is acknowledged to have the largest higher education systems in the world in terms of number of institutes. Higher education is the second largest opportunity in the Indian education sector. There has been phenomenal growth of higher education in India since Independence. These numbers have increased by 26 times in the case of universities and 66 times in the case of colleges. (Sudararajan and Gopal, 2016). College selection is one of the many important choices students make in determining future career plans. The governance of the higher education system throughout the world has changed considerably in the recent years. The number of unaided college is increasing year after year; hence students are getting wider choice to select the best suitable college for higher studies.

 Abstract

Many researches are conducted on increasing the efficiency of Flyback boost converter (FBC) applied for power factor correction (PFC) by using high-performance power electronics devices and soft switching circuits, which is not helpful to reduce hardware cost and systematic complexity. In this paper, three intrinsic parameters affecting efficiency of FBC PFC are found and analyzed, including switching frequency value, boost inductor value and output voltage value. Based on the above findings, combining with limitations of current ripple, power factor, maximum magnetic flux density and volume of boost inductor, an optimization design method for high-efficiency FBC PFC is proposed. A PFC prototype is developed based on Si devices. Experimental result verifies that the proposed method can improve efficiency of FBC PFC with low-cost low-performance devices in the full-load range.

 Abstract

Man is a social begin. He decides same aims and objectives for his future. To obtain these aims and objectives he makes a lot of efforts following social, moral and religious norms. These are generally known as values, viz social values, moral values, political values and religious values. Values are does which produce belief faithfulness, responsibility, kindness, gratitude, honesty and regularity in the heart of human being. Values followed by different people particularly different cultures defers sharply. An object of belief valuable for one person may not be valuable for the others. Society has different set of value according to their socio-cultural set-up and these values change from time to time with influx of new technologies and new opportunities. In this study it is tried to find out the values of the students of senior secondary level. Survey method, random sampling technique and self made tool for data collection are used to conduct the study.

 Abstract

Background: Patellofemoral pain is one of the most common clinical conditions presenting to clinicians who treat musculoskeletal conditions. Patellofemoral pain syndromes is a general terminology which suggests that damage exists beyond the articular cartilage. Patellar malalignment and/or abnormal patellar tracking is thought to be one of the primary precursors of patellofemoral joint pathology. Yoga is an ancient Indian science and way of life which talks about the origin of diseases. The dynamic component of asana strengthens the musculoskeletal framework and the static component relaxes the neuromuscular framework. Many studies have been conducted focusing on different open chain and closed chain kinetic exercises, manual therapy, dry needling, patellar taping and footwear correction. But no significant study has focused on the wholistic effects of yoga in patellofemoral pain syndromes. Hence, primary aim of this study is to find out Effect of Yoga Therapy in Patellofemoral pain syndromes. Methodology: 63 subjects fulfilling the inclusion and exclusion criteria were randomly allocated into two groups. Group A participants were given Yoga Therapy and Group B participants were given conventional physiotherapy exercises. The outcome measures included in the study were Numerical Pain Rating Scale (NPRS), Knee Osteoarthritis Outcome Survey- Patellofemoral Subscale (KOOS-PF) and Medical Outcome Study Questionnaire Short Form 36 (SF-36). Results: Independent t-test was used to find out the effectiveness of Yoga Therapy compared to that of conventional physiotherapy in Patellofemoral Pain Syndromes. Results for NPRS and KOOS-PF showed that p-value was less than 0.0001 that is highly significant at 95% confidence limits. For SF-36, physical function, energy and emotional wellbeing components showed highly significant p-vale<0.0001; social function, pain and general health components showed significant p-value<0.05 whereas role limitation due to physical function and emotional problem components showed no significant difference. Conclusion: Results of the present study indicate that an integrated Yoga Therapy program is effective to reduce level of pain and improve function in patients with Patellofemoral pain syndromes compared to that of conventional physiotherapy exercises. So, Yoga Therapy can be used as an adjunct to conventional physiotherapy exercises in management of Patellofemoral pain syndromes.

 Abstract

IDs and MRTDs (Identification and Machine- Readable Travel Documents) are used to perceive and authenticate identities in numerous situations which include crossing countrywide borders, in civil applications, income and shopping portals, or admission to transaction processing structures. These files have numerous safety functions which mitigate and fight record forgery. As those safety structures are tough to circumvent, crook assaults on ID verification structures are actually specializing in fraudulently acquiring true files and the manipulation of the facial portraits. To lessen dangers associated with this fraud problem, it's far essential the ones governments and producer of IDs and MRTDs constantly increase and enhance safety measures. With this in mind, we introduce the primary green steganography method StegoFace is an cease-to-cease facial photo steganography version this is fashioned through n Deep Convolutional Auto Encoder, that could cover a mystery message in a face portrait and, hence, generating the stego facial photo, and a Deep Convolutional Auto Decoder, that's capable of study a message from the stego facial photo.
