Green Finance: The Future of Sustainable Banking in India
Get PDFIndia is now in a situation where it has to accept the challenges from the international forum to improve its green infrastructure and attain its sustainable developments goals and climatic challenges like global warming, its huge population and huge green depletion. If the country has to survive it has to adopt Green finance. Green finance or climate finance is a component where it has to change it’s focus and behaviour from traditional form of financing to more environment friendly financing. It has to build a strategy through green finance to achieve its sustainable development goals. Indian and international financial agencies, corporates need to be encouraged to refocus on the aspect of green finance. There has been lot of promises and challenges in this front. This study is an effort to understand the situation where India stands and the go ahead as far as green finance and to manage its sustainable development goals. This study is of descriptive in nature and is based on secondary data derived from various international and national agency reports, which includes report from Government of India
Aerodynamic characteristics of owl like airfoil at low reynolds number
Get PDFThe computational investigation of aerodynamic characteristics and flow fields of a smooth owl-like airfoil without serrations and velvet structures.The bioinspired airfoil design is planned to serve as the main-wing for low-reynolds number aircrafts such as (MAV)micro air vechiles.The dependency of reynolds number on aerodynamics could be obtained at low reynolds numbers.The result of this experiment shows the owl-like airfoil is having high lift performance at very low speeds and in various wind conditions.One of the unique feature of owl airfoil is a separation bubble on the pressure side at low angle of attack.The separation bubble changes location from the pressure side to suction side as the AOA (angle of attack) increases. The reynolds number dependancy on the lift curve is insignificant,although there’s difference in drag curve at high angle of attacks.Eventually, we get the geometric features of the owl like airfoil to increase aerodynamic performance at low reynolds numbers

An Empirical Analysis on Investor\u27s Perception under the Prevailing Pandemic based on Select NSE Indices
Get PDFAbstract
The Covid-19 pandemic has made the
whole world standstill and urged
individuals to think and look every
perspective in a different way. The corona
virus pandemicaffected the economy from
losing jobs to falling in market
capitalization along with losing human life
and several other factors associated with
it. The pandemic situation have forced the
world stock market to crush and the speed
with which the market nosedived, it
shocked the entire world. In a situation
like this where every aspect of the society
is getting affected due to the pandemic, the
researcher should look upon on the
societal aspect for the benefit of the society
as well especially in this pandemic
situation. Due to the pandemic, there is a
liquidity crisis in the market and also
instability in the financial market and such
financial market disruptions will have a
negative impact on the investors’
perception while investing in the market.
Therefore, under this study, the
researchers have conducted an empirical
analysis of the changes in several NSE
indexes’ values in pre pandemic lockdown
period and thelockdown period by
applying One-Tailed Paired t-test for
means. The observations are quite clear
that the investors’ perception has turned
negative in this pandemic situation.
Several recommendations have also been
provided by the researchers to bring the
market back in track to normalcy and to
escort the confidence of investors. The
appropriate causes behind such
perceptional changes among the investors
along with future research scope have also
been identified by the researcher in this
study
Five Level Flying-Capacitor Multilevel Converter Using Dynamic Voltage Restorer (DVR)
Get PDFThis paper deals with dynamic voltage restorer (DVR) controlled by a five-level flying-capacitor multi level converter. To decrease the power-quality disturbances in distribution system, such as voltage imbalances, harmonic voltages, and voltage sags. The organisation of this paper has been divided into three parts; the first one eliminates the modulation high-frequency harmonics using filter increase the transient response. The second one deal with the load voltage; and the third is flying capacitors charged with balanced voltages. The MATLAB simulation results effectively for five level flying capacitor multilevel converters charged with balanced voltage regulation
VARIED MANIFESTATION OF DEPRESSION IN WOMEN
Get PDFMen and women might experience various kinds of depression in varied ways, and while they do share many signs and symptoms, experts argue that deeper insights into distinctions can benefit affected individuals. The death rate amongst women due to depression has been twice the rate of men during the Covid 19 pandemic, be at home or at frontlines. Our paper aimed to evaluate the disparities found at the onset of Covid 19 in the areas of mental health and domestic violence between men and women. During Covid-19 pandemic very limited research was conducted on the mental health issues of women. We believe that this paper will contribute to recognise the role that women play both at home and at work
IMPLEMENTATION OF TRANSONIC AREA RULE AND SWEPT BACK DELTA WING DESIGN ON AN AIRCRAFT
Get PDFAbstract-The transonic area rule was first implemented in the 1950s. It is an important concept related to the drag on an aircraft or other body in transonic and supersonic flight which states that two airplanes with the same longitudinal cross-sectional area distribution have the same wave drag, independent of how the area is distributed laterally. A swept back delta wing increases the critical Mach number of the wing and performs well at low speeds, as a result of unique swirling vortices that form on the upper surface of the wing. BOOM Supersonic plans to bring back Supersonic Commercial aircrafts by implementing these modifications in the famous Concorde. In this paper two aircraft designs inspired by Concorde and BOOM Overture are compared using ANSYS Fluent. These were designed in CATIA with changes in fuselage dimensions, wing configuration and engine configuration. The lift to drag ratio of both the designs are calculated and compared. Pressure contours, velocity vectors, vector pathlines, turbulence pathlines and pressure pathlines are also compared. The results show that the design with the implementation of transonic area rule and swept back delta wing has a better Lift to Drag ratio when compared to the design with a wide fuselage and a delta wing design
Three-Dimensional Computational Fluid Flow Analysis of Bio-inspired Corrugated wing at Low Reynolds Number
Get PDFA computational study was performed to analyze the airflow over bio-inspired corrugated wings. The bio-inspired corrugated wing profiles were derived from the mid-span section of the forewing of Aeshna Cyanea dragonfly species. Additionally, a hybrid non-corrugated profile was also created possessing geometric similarities with the corrugated airfoils to compare and visualize the effects of corrugation on the fluid flow. The computational analysis was conducted for 4,8-, and 12-degrees angles of attack. Streamlines obtained from the computational analysis results (carried out on ANSYS CFX) showed the formation of secondary flows or vortices that are trapped in the valleys of the corrugated wings which was not observed in the hybrid airfoil. This study also compares the effects of corrugation geometry on fluid flow behavior. It was also seen that the intensity and quantity of the secondary flows increased with the increase in the angle of attack
Finite Element Study on the Effect of Geometrical Parameters on the Mechanical Behavior of 3D Reentrant Auxetic Honeycombs.
Get PDFAbstract
Auxetic materials are a special case of cellular materials, which exhibit a negative Poisson’s ratio. This in fact is the reason behind their peculiar behavior i.e. lateral shrinkage under longitudinal compression and vice versa. Since these materials do not obey the laws of “normal” materials and go beyond common sense, they are still an emerging class which can be put to use for various purposes like self-locking reinforcing fibers in composites, controlled release media, self-healing films, piezoelectric sensors, and also be used in biomedical engineering. Their stress-strain behavior, Poisson’s ratio and impact energy absorption are controlled by bulk material as well as the unit cell geometry. Among many forms of auxetic structures available, we have chosen a three-dimensional reentrant auxetic honeycomb unit cell. The unit cell geometrical parameters were taken from literature. In this study, we try to understand the effects of strut angle through finite element simulations while keeping the bulk material, unit cell size, strut thickness and number of repetitions constant. A total of three different angles were tested, based on which we conclude that as angle increases, the Poisson’s ratio increases and Energy absorption is maximum at 30 deg
