Why do you think that approximately one-sixth of the worlds popula.pdfanasmukerji
Why do you think consumers can be influenced by changes in the level of interest rates?
Solution
Ans;Interest rate is the annualized cost of credit or debtcapital computed as% ratio of interest to
the principle or in simple words it is the interest paid by borrower to the lender on the amnt
which he owed from lender.
Interest rate is a monetary tool to achieve the goal of price stability and economic
growth.changes in interest rate influence money supply and eventually trickle down to
consumers.interest rates are reduced to stimulate economic growth. lower interesrt rates
encourage borrowing and invt i.e when int rates are low they can spur ecessive growth and
inflation.Inflation eats away purchaising power of consumer and undermine the stability of
desired expansion.A tax cut can also help consumer by saving money by reduced interest on
certain type of financing.
On the other hand rise in interest rate reduces or slowed down inflation,reduce greater
availability of credit to consumers and tightens money supply.
Thus, we can say changes in the interest rates influenced consumers..

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.

3. INTRODUCTION :
About 250 years ago, humanity existed relatively small
numbers with limited technologies.
Any environmental disturbances caused by people were
local and usually well with in the environments
capacity to absorb them.
In the last two centuries, developments have occurred
that have created environmental problems beyond
nature’s assimilative capacity.
Explosive growth of population creates environmental
pressure because of the sheer number of people on
earth.
4. POPULATION :
A Population is defined as a group of individuals
belonging to the same species which line in a given
area at a given time.
The study of population change is known as
“population dynamics”.
POPULATION DENSITY :
It is expressed as the number of individuals of the
population per unit area or per unit volume.
This varies in response to changes in the
environment and introduction with other living
organism.
5. PARAMETERS AFFECTING
POPULATION SIZE :
BIRTH RATE OR NATALITY : Number of live birth per
1000 people in a population in a given year.
DEATH RATE OR MORTALITY : Number of death per 1000
people in a population in a given year.
IMMIGRATION : Arrival of individuals from
neighbouring population.
EMIGRATION : Dispersal of individuals from the
original population to new areas.
6.
7. POPULATION GROWTH :
The rapid growth of the global’s population for the
past 100 years results from the difference between the
rate of birth and death.
CHARACTERISTICS OF POPULATION
GROWTH:
EXPONENTIAL GROWTH :
Population growth shows the dramatic increase in
global population in the past 160 years.
8. DOUBLING TIME :
It is the time required for a population to double its size
at a constant annual rate.
Td = Doubling time = 70/r
Where, r = annual growth rate
(e.g.) if a nation has 2% annual growth, its population will
double in next 35 years.
INFANT MORTALITY RATE :
It is the percentage of infants, died out of those born in
one year.
Even through this rate has decreased in the last 50
years the pattern differs widely in developing and developed
countries.
9. TOTAL FERTILITY RATES (TFR) :
It is the average number of children delivered by
women in her life time.
The TFR values vary from 2 in developed countries
to 47 in developing countries.
REPLACEMENT LEVEL :
Two parents bearing two children will be replaced
by their off spring.
Due to infant mortality this replacement level is
changed.
10. MALE – FEMALE RATIO :
The ratio of girls and boys should be fairly
balanced in a society to flourish.
But the ratio has been upset in many countries
including china and India.
DEMOGRAPHIC TRANSITION :
Population growth is generally related to economic
development.
The death rates and birth rates fall due to improved
conditions.
11.
12. VARIATION OF POPULATION
AMONG NATIONS :
Different regions of the world find themselves at different
stages of demographic transition from high to low mortality
and fertility.
Their growth path also differ considerably, resulting in
significant shifts in the geographical distribution of the
world’s population.
At present the world’s population has crossed 7 billions.
This existing population is also not evenly distributed.
Less developed countries have 80% population while the
developed countries have only 20%.
13.
14. VARIATION OF POPULATION
BASED ON AGE STRUCTURE :
Their classification are…
Pre – productive population (0 – 14 years )
Re – productive population (15 – 44 years )
post re-productive population (above 45 years )
PYRAMID SHAPED VARIATION OF
POPULATION ( INCREASE ) : The large number
of young age people will soon enter into reproductive age
group population ( 15 – 44 years), which increases the
population growth. But the less number of old age
people indicates less loss of population due to death.
(e.g.) India, Bangladesh, Ethiopia – Nigeria etc…
15. BELL SHAPED VARIATION OF POPULATION
(STABLE) : (e.g.) France, UK, Canada etc…
The pre – productive age group and reproductive
age group population are more or less equal.
So the people entering into reproductive age group
will not change the population and thus the population
growth is stable.
URN SHAPED VARIATION OF POPULATION
(DECREASE) : (e.g.) Germany, Italy, Sweden, etc…
The pre – productive age group is smaller than the
reproductive age group population.
In the next 10 years, the number of people in the
reproductive age group is less than the before, resulting
in a decrease of population growth.
16.
17. POPULATION EXPLOSION :
DEFINITION :
The enormous increase in population, due to low
death rate (mortality) and high birth rate (Natality) is
termed as population explosion.
The human population is not increasing at a
uniform rate in all parts of the world.
Among the countries, the most developed country
like USA has a slow growth rate, whereas the other
developing countries have exorbitant growth rates.
Birth rate of developing country=45 per 1000 population
Birth rate of developed country=12.7 per 1000 population
18.
19. DOUBLING TIME :
Doubling time can be defined as “number of years
needed for a population to double in size”.
In many non – industrialized, poor developed countries
like Asia, Africa and South America shows higher
growth rate.
In contrast the population of industrialized, developed
countries like USA, UK, France and Italy shows lower
growth rate.
20. CAUSES (OR) REASONS FOR
POPULATION EXPLOSION :
Reduced death rate and increased birth rate by the
invention of modern medical facility, which leads to
population explosion.
Increase of life expectancy.
Ex: In 1950, the average life expectancy of human
being was 50 years but now it is 61 years.
Illiteracy.
21. EFFECT OF POPULATION
EXPLOSION :
Infant mortality is one of the most tragic indicators of
poverty. There are still 34 developing countries, where
more than 10 children die before he or she reaches the
age of five.
Population explosion leads to environmental
degradation.
Many of the natural and renewable resources like
forest, grassland are also under threat.
Increase in population will increase disease, economic
inequity and communal war.
