A soft switching dual flyback DC-DC converter for renewable energy applications

The world’s total energy consumption is higher than its production. With respect to the efficiency, it is known that the conventional energy sources say fossil fuels, is used much more than the non-conventional energy sources. Due to the over-consumption of energy from fossil fuels, after few years it may extinct and thousands of years are needed to produce fossil fuels. Hence, non-conventional energy sources must be used as an alternative source of energy production. One of the renewable energy sources which are available in bulk is solar. But the energy production from solar is not as efficient as that of fossil fuels. Hence, a DC-DC converter has to be built to enhance the solar power. A DC-DC Flyback converter with soft-switching is been built which increases the output voltage of the solar power depending upon the Flyback transformer ratio.

Analysis of characteristics of thermal power plant ash to replace the sand in concrete

Pond powder is one, crazy of three classifications of fly cinder accessible from warm control stations. Different two classifications are dry fly powder Also lowest part ash, dry the fly powder may be gathered starting with different rows about Electro-static precipitators On the dry form, bottom fly cinder may be gathered during those base for heater furnace, Pond powder may be gathered starting with powder Pond region. Pond powder will be wasted Also by-products for the warm energy plant, have been presented under Indian cement industry should save regular assets from claiming parts of cement. Done India, practically of the warm force plants receive wet system for power transfer. contiguous particles likewise cement assumes a paramount part done long-term time for structure something like that it may be likewise imperative to weigh impact for sturdiness The secondary powder content (30- 50%) of the coal in, India makes this issue complex. Toward present, regarding 80 warm energy stations prepare About 100 million tonsils from claiming coal powder for every annum.

Introducing an improved e-exam system with the question highlight/marking feature to diminish the candidate’s discomfort

In today’s era, almost all exams job-oriented as well as institutional are carried out through computer systems (commonly known as e-exam). This approach is very efficient as it is suitable for large-scale implementation, it is secure, and provide very fast results but it has demerit as candidates feel discomfort in attempting questions because they don’t have much control over the question area. They don’t highlight or mark the important information of the question. This waste their time in solving complex problems like reasoning puzzles, code snippets etc. In this paper, we introduce a new feature of highlighting the text in the question view-area so that user can mark/highlight the important portion of the question and used it in solving the question quickly. Our demonstration and result analysis show 85% of the students (17 out of 20) find our proposed system useful and more comfortable than the existing system.

Design of hardened by design charge pump PLL

The PLL is a feedback system used to generate clock signal in microprocessors, and frequency multiplication (FM) etc., The PLL consists of several components such as Phase frequency detector (PFD), Charge pump (CP), low pass filter (LPF), voltage controlled oscillator (VCO) and frequency divider (FD) circuits. The struck at single-event-effects (SEEs) such as latch-up, single-event-transient and multiple bit upsets which affect the PLL performance. PFD and FD which are free from dead zone due to there digital characteristics but the CP are affected by SEEs which causes the CP output to be degraded and which affect the VCO input hence PLL will lose lock. The PLL and its components are implemented in cadence virtuoso tool using 180nm technology.

Effect of nano-silica on mechanical properties and internal structure of pozzolanic concrete

In this research work, advancement of nanotechnology is used in order to improve performance characteristics of pozzolonic concrete (concrete having 30% class F fly ash in replacement of cement) with use of nano-sized silica (SiO2) particles, known as Nano-silica. This study may be considered as an important step towards better understanding the use of nano-silica in concrete as a remedy to overcome drawbacks of the use of pozzolans (drawback like late strength gain of hardened concrete). This research program aims at 1) further understanding the behavior of cementitious materials when amended by nano-silicon various physio-mechanical properties (workability, compressive, tensile, flexural strength etc.) of pozzolanic concrete and 2) exploring the effect of this enhancement on the microstructure of cement matrix using SEM. The experimental program that was conducted included a laboratory investigation of concrete mixtures in which nano-silica was added to the compound cement and Class F fly ash. Three ratios of nano-silica (0%, 3% and 6% by wt. of the cementitious compound) were used in concrete mixtures to examine the extent and types of improvements that could be imparted to concrete. The conducted experimental program assessed these improvements in terms of mechanical properties and internal structure of the mixtures under investigation.

Study on road accident and improved safety measures of road accident

Road accidents are an outcome of the interplay of various factors, some of which are the length of the road network, vehicle population, human population and adherence/enforcement of road safety regulations etc. Road accident causes injuries, fatalities, disabilities, and hospitalization with severe socio-economic costs across the country. Road traffic injuries cause considerable economic losses to victims, their families, and to nations as a whole. Almost 90% of the world's fatalities on the roads occur in low- and middle-income countries, even though these countries have approximately half of the world's vehicles. Half of those dying on the world’s roads are “vulnerable road users”: pedestrians, cyclists, and motorcyclists. Without action, road traffic crashes are predicted to rise to become the 7th leading cause of death by 2030.
