The Indian Stock Market and the Great Recession

This study analyzes the impact of the outbreak of the Great Recession of 2007 on the behavior of the Indian stock market. The SENSEX index of the Bombay Stock Exchange is analyzed for the prerecession period of January 2002 – November 2007 and the postrecession outbreak period of December 2007 – July 2010. Substantial increase in SENSEX return volatility observed during the post-recession outbreak period, whereas no substantial difference in returns between two periods is found. Also strong co-movements in returns and volatility are observed between the SENSEX and other major stock indexes during the post-recession period. Our results establish the dominance of global factors in influencing Indian stock market behavior during periods of economic turmoil

Artificial Intelligence-Based Profit Strengthening of Wind Farm

Ensuing the undertakings of the Paris Agreement of 2015 and the United Nations Climate Change conference of 2021, several nations are making every effort to decarbonize their electricity generation industries through the competent utility of renewable means. Wind power has reaped massive acceptance internationally as a substitute and low-carbon resource for electricity generation. In this research work, artificial intelligence has been exercised to heighten the profitability of a wind farm at a nearshore power generation site in India. A state-of-the-art amendment of the genetic algorithm has been projected to augment the design of two arbitrarily selected layouts. The optimization consequences corroborate the ascendancy of the projected procedure over the typical genetic algorithm and binary particle swarm optimization algorithm for expanding the annual profit of the wind power generation system

Selection of Suitable Lubricant for Sliding Contact Bearing and the Effect of Different Lubricants on Bearing Performance: A Review and Recommendations

The word bearing implies to an element of the machine which allows one moving or vibrating part to support other rubbing surfaces by which the load can transmit. Depending upon in nature and application of load, an extensive variety of different bearing is available. They can generally be categorized into two kinds of bearing such as rolling element bearing and a sliding bearing. Lubrication is required in the middle of rubbing surfaces, which enacts as a medium between the moving surfaces to diminish friction and to take away heat for survival during the transmission of the load. In this paper, a literature review has been made on the influence of different lubricants on the performance of various bearing. The selection of an appropriate lubricant is a very critical decision to take for the efficient performance of a bearing because each lubricant has its own merits and demerits on various kinds of bearing. In the later portion of this paper, a selection process of right lubricant in sliding contact bearing is analyzed mathematically. This critical decision is being made by using PROMETHEE method (broadly Preference Ranking Organization Method for Enrichment Evaluations) hybridized by Entropy Weight Measurement method and Fuzzy scale. As per the ranking of Entropy-PROMETHEE method, the best suited lubricant for sliding contact bearing is SAE20W40

A Comparative Analysis of Genetic Algorithm and Moth Flame Optimization Algorithm for Multi-Criteria Design Optimization of Wind Turbine Generator Bearing

As global climate change is affecting the meteorological conditions and instigating massive social suffering, the emanation of greenhouse gases is necessitated to be restricted through effective usage of renewable sources of energy as per the directions of the Paris treaty of 2015. Wind energy, a renowned renewable energy resource, is enabling countries to generate power in a relatively cost-effective way and causes a remarkably nominal carbon trail. A considerable extent of the functioning lifespan of wind turbines remains unexploited every year all over the globe because of mechanical malfunctions. The existing research strives to evaluate the relative competency of the Genetic Algorithm (GA) and the Moth Flame Optimization Algorithm (MFOA) for optimizing the wind turbine generator bearing design through enhancement of its static and dynamic load-bearing capacities. The design solutions attained by both of the algorithms validate a noteworthy growth of the optimization objectives when contrasted with the technical catalog standards. Moreover, the relative evaluation demonstrates the superior aptness of multi-criteria GA on multi-criteria MFOA for finding improved design resolutions

Expanding the Yearly Profit of Wind Farm Using Genetic Algorithm with Variable Allocation Method of Possibilities for Crossover and Mutation Procedures

With rising surface air temperature, global communities are continually struggling to restrict the production of greenhouse gases through the competent application of renewable resources. Being a proficient alternative to traditionalelectricity generation technologies, wind energy can facilitate nations to achieve their carbon neutrality goals. This paper aims to enhance the annual profit of wind farms using an enriched genetic algorithm. Innovative dynamic techniques for allotting the chances of crossover and mutation procedures have been employed for the genetic algorithm-based optimization process accompanied by the established static tactic. The evaluation consequences of the projected procedure have been contrasted with the results accomplished by the genetic algorithm with the standard static method of apportioning the crossover and mutation probabilities. The evaluation outcomes authorize the preeminence of the new non-linearly escalating procedure over the static tactic of allotting the crossover and mutation prospects for achieving a more optimal yearly profit

Prevalence of obesity in affluent school children of Greater Noida, Uttar Pradesh

Background: Childhood obesity is a state of over nutrition with long term complications such as hypertension, coronary artery diseaseand Type-2 diabetes. It also adversely affects psychological development causing poor body image and low self-esteem. Objective: Theaim of this study was to know the prevalence of obesity in affluent school children of Greater Noida, Uttar Pradesh. Methods: This studywas carried out in affluent school children of four private schools in Greater Noida, Uttar Pradesh. Height and weight of each child weremeasured, and body mass index was determined according to Quetelet’s index. Results: Totally 816 school children of 6-11 years wereexamined with 528 boys and 288 girls. The overall prevalence of obesity was 7.4% without significant difference in boys (7.3%) and girls(7.6%). Prevalence of obesity was high at the age of 11 years both in boys (12.2%) and girls (11.5%). Conclusion: The present studyrevealed that obesity has a high prevalence reaching to epidemic proportions in the affluent school children of Greater Noida, Uttar Pradesh

Effect of phototherapy on serum calcium levels in neonates receiving phototherapy for neonatal jaundice

Background: To study the occurrence of hypocalcaemia in neonates with physiological unconjugated hyperbilirubinemia after 48 hours of phototherapy or at the end of phototherapy, in case duration of phototherapy was less than 48 hours.Methods: This prospective study was conducted on 100 term neonates (61 males and 39 females) admitted to Neonatal intensive care unit of Teerthankar Mahaveer Medical College, Moradabad with unconjugated hyperbilirubinemia and requiring phototherapy. Total Serum bilirubin levels and serum calcium levels were checked before and after phototherapy. Neonates were assessed for clinical features of hypocalcemia i.e. jitteriness, irritability/excitability, lethargy and convulsions.Results: After phototherapy, there was hypocalcemia in 35.0% neonates. The difference between pre and post phototherapy serum calcium levels were found to be statistically significant (p <0.001). 2.86% of neonates developed jitteriness among those who had hypocalcemia. Hypocalcemia was more in subjects who received phototherapy for longer duration.Conclusions: Hypocalcaemia is a common complication of phototherapy. Therefore, calcium supplementation should be done in all neonates undergoing phototherapy

Does NOTA Affect Voter Turnout? Evidence from State Legislative Elections in India

This paper explores the impact of introduction of the ‘None of the Above’ (NOTA) option in Indian legislative elections. NOTA was introduced as a ballot option following the Supreme Court ruling in 2013 based on the argument that more choices to voters will enhance voter participation. We take advantage of the state-time variation in introduction of NOTA option in state legislative assembly elections in 2013 to study its impact on voter turnout. Using election data from five major Indian states between 2008 and 2013, we find evidences suggesting that NOTA may not have led to increased voter participation. However, our results are not conclusive

A Simple Model on Mothers’ Autonomy, Health Inputs, and Child Health

Using traditional health capital model of Grossman (1972) and Wagstaff (1986a) this paper attempts to fill in the theoretical missing link between mothers’ autonomy and household consumption behavior, particularly focusing on the consumption of child health inputs. It has been shown in this analysis that working mothers’ children should be of better health status. Further independent of working status of the mother, the autonomy parameter always induces consumption of more health inputs for the children. However, when autonomy is linked with mothers’ income, the basic results of the model are further strengthened. In fact, income induced autonomy may result in redefining the composite consumption good for the family as an inferior one
