The document discusses Gunnar Myrdal's theory of cumulative causation, which proposes that economic development leads to uneven growth between developed "core" regions and less developed "periphery" regions. It describes the concepts of the "backwash effect," where core growth drains resources from the periphery, and the "spread effect," where core development begins to benefit the periphery. As an example, it outlines how Japanese factories began relocating to Thailand in the 1990s due to rising costs, creating jobs and technology transfers in a demonstration of the spread effect. The theory of cumulative causation suggests that government intervention is needed to promote the spread effect and reduce inequality between regions.
Geographic Regions: by definition There three types of regions Formal regions are areas where a certain characteristic is found throughout. Functional regions consist of a central place and the surrounding places affected by it. Perceptual regions are defined by people’s attitudes and feelings about areas. 4.

What is Urban Geography?
It can be considered a sub-discipline of the larger field of human geography with overlaps of content with that of Cultural Geography
Definition of Urban Geography.
Urban geography is the study of urban places with reference to their geographical environment.
Urban geography is the sub discipline of geography which concentrates on those parts of the Earth's surface that have a high concentration of buildings and infrastructure
.
It is that branch of science, which deals with the study of urban areas, in terms of concentration, infrastructure, economy, and environmental impacts.
Griffith Taylor- Urban Geography includes the site revolution pattern and classification of towns.
Dudley Stamp- Urban Geography is infecting the intensive study of town and their development in all their geographical aspects.
Meaning of an Urban Place
UN Demographic Year Book concludes: “There is no point in the continuum from large agglomerations to small clusters or scattered dwellings where urbanity disappears and rurality begins the division between urban and rural populations is necessarily arbitrary.”
A review of the problems of rural and urban centres as revealed by the Census Reports of various countries identifies a few bases for reckoning a place as urban.
Difference between rural and urban depends upon their nature of work – the former being engaged in agricultural operations and the latter in non-agricultural activities.
Criteria of an Urban Place
(1) A place designated by administrative status;
(2) A minimum population;
(3) A minimum population density;
(4) A concept of contiguity to include or exclude under suburban area or loosely scattered settlement;
(5) A proportion engaged in non-agricultural occupations; and
(6) A functional character.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

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.

Hybrid optimization of pumped hydro system and solar- Engr. Abdul-Azeez.pdffxintegritypublishin
Advancements in technology unveil a myriad of electrical and electronic breakthroughs geared towards efficiently harnessing limited resources to meet human energy demands. The optimization of hybrid solar PV panels and pumped hydro energy supply systems plays a pivotal role in utilizing natural resources effectively. This initiative not only benefits humanity but also fosters environmental sustainability. The study investigated the design optimization of these hybrid systems, focusing on understanding solar radiation patterns, identifying geographical influences on solar radiation, formulating a mathematical model for system optimization, and determining the optimal configuration of PV panels and pumped hydro storage. Through a comparative analysis approach and eight weeks of data collection, the study addressed key research questions related to solar radiation patterns and optimal system design. The findings highlighted regions with heightened solar radiation levels, showcasing substantial potential for power generation and emphasizing the system's efficiency. Optimizing system design significantly boosted power generation, promoted renewable energy utilization, and enhanced energy storage capacity. The study underscored the benefits of optimizing hybrid solar PV panels and pumped hydro energy supply systems for sustainable energy usage. Optimizing the design of solar PV panels and pumped hydro energy supply systems as examined across diverse climatic conditions in a developing country, not only enhances power generation but also improves the integration of renewable energy sources and boosts energy storage capacities, particularly beneficial for less economically prosperous regions. Additionally, the study provides valuable insights for advancing energy research in economically viable areas. Recommendations included conducting site-specific assessments, utilizing advanced modeling tools, implementing regular maintenance protocols, and enhancing communication among system components.

4. • Theory of Cumulative causation, proposed by Professor Gunnar Myrdal who has
received more than thirty awards in his lifetime including the Nobel Prize in
1974 for his ‘pioneering work in the ‘theory of money and economic fluctuations
and penetrating analysis’ of the interdependence of economic, social and
institutional phenomena.
• Prof. Gunnar Myrdal maintains that economic development results in a circular
causation process leading to rapid development of developed countries while
the weaker countries tend to remain behind and poor
• The concept of Core and Periphery- Development and underdevelopment
Cumulative causation
Region A

Give and Take
5. Cumulative causation
• Developed Countries /Region are known as the core, and Low Developed
Countries/Region are referred to as the periphery
Core countries/Regions
Periphery
countries/Regions
6. Cumulative causation
• Developed Countries /Region develop at the cost of Low Developed
Countries/Region–Case example of Angola and Portugal- In return Angola also
benefits- Concept of Colonialisation in India before 1947 ( A simplistic example)
7. Cumulative causation
Un even development-Concept of Backwash effect and Spread effect
What is the backwash effect?
• Pulling off all dynamic elements to
the growth center from the
surrounding location is called the
backwash effect.
• Core grows –Attracts
labour and brain drain
from the periphery
• Profit controlled by core-
very little reaches the
Periphery
• Flow of raw materials and
labour leaves the
periphery at
disadvantages
8. What is the spread effect?
During the time, the growth center or the big
cities/core regions began to decrease due to
pollution and congestion or other reasons. It
leads to pulling out the resources from big
cities/core and there is a spread of
development of the periphery region around
this growth center. This effect is called the
spread effect.
Cumulative causation
• Spread of wealth and
Knowledge from core
to periphery
• Benefits of core starts
to redistribute amongst
the periphery
• Narrows disparities.
• Called as Centrifugal
growth
9. Case study of Spread effect- Thailand –Japan Car industry
Cumulative causation
• In 1990’s due to
extreme cost of car
manufacture in
Japan, many
industries started to
look for cheap labor
and cost effective
destinations
• Factories started to
relocate to Thailand
• Jobs and investment
flow for Thailand
• Transfer of
technologies to
Thailand Illustration of Spread effect-Centrifugal Growth
• Concept of Make in India
• Industrial locations of IT/ITES/ Manufacturing hubs of Automobiles / smartphone in India
and China –Gujarat-TN-Hariyana egs of such regions
• Many US/Japan/EU companies started functioning their industries in India and China
10. Detailed demonstration :
• On a regional scale, the introduction of a new industry/economic activity or the
expansion of an existing industry /economic activity in an area also encourages
growth in other industrial/economic sectors also.
• This is known as the multiplier effect which in its simplest form is how many times
money spent circulates through a country's economy.
• Money invested in an industry helps to create jobs directly in the industry and
locality , but it also creates jobs indirectly elsewhere in the economy.
• New industrial development, for example, requires construction workers who
themselves require housing, and services such as schools and shops. An increased
demand for food will benefit local farmers who may increase their spending on
fertiliser.
• Workers employed directly in the new industry increase the local supply of skilled
labour, attracting other companies who benefit from sharing this labour pool. Other
companies who supply components or use the new industry's products are attracted
to the area to benefit from reduced transport costs.
• Spin-off effects include new inventions or innovations that may lead to further
industrial development and new linkages.
• Through this multiplier effect, an area can develop as a growth pole
Cumulative causation
14. • The cumulative causation effect is mostly circular in nature. Hence it is also
called as the circular cumulative causation effect.
• Back wash effect and spread effect has far reaching application in international
trade, regional development and much more
• The main cause of Underdevelopment and backward effect is backwash effect
and poor spread effect
• Developed countries/Regions Vs Underdeveloped regions
Cumulative causation
Balancing the SPE & BWE is the challange
15. • Cumulative causation theory proves that ???
• Market mechanism will not provide equality, but will increase inequality
• Government intervention and polices should address the same
• Spread effect to be promoted by providing import surplus industries there by
making the spread effect
• Institutional reforms are mandatory for such changes.
• Proper regional planning can increase the spread effect and reduce the Back
wash effect.
