The flooding in western Japan in July 2018 killed over 200 people and left 44 missing. Torrential rains fell over several days, with some areas receiving over 25 inches of rain. The extreme downpour caused rivers to overflow and triggered landslides, destroying homes and infrastructure. Rescue efforts involving over 70,000 workers continued for days to search for survivors amid the wreckage and receding floodwaters. The disaster highlighted Japan's vulnerability to increasingly heavy rains and landslides caused by climate change.

?
K38 Japan and Mr. Hiroaki Kishi who began the program with his trusted colleagues worked in the aftermath of the Tohoku tsunami flood debris to help a community clear their waters to bring normalcy back to their lives.
Typhoon Vongfong made landfall in Japan, bringing strong winds of up to 180 km/h and heavy rain. At least one person was reported missing and dozens injured. Over 500 flights were cancelled as the typhoon was forecast to affect large parts of the country through Tuesday, bringing landslides, floods and further damage. Search efforts for victims of a recent volcano eruption were suspended due to the typhoon.
This document contains summaries of four natural disasters: the 2013 Jakarta floods, Typhoon Haiyan from 2013, the 2010 eruption of Mount Merapi volcano, and the 2004 Indian Ocean tsunami that devastated Aceh province in Indonesia. Each summary includes key details about the location, causes, impacts, damage and casualties of each respective disaster. Photos and maps are also included to provide visual context about the events.
Natural disasters are major changes in the Earth that can damage land and threaten lives. They include earthquakes, floods, tsunamis, wildfires, and cyclones. An earthquake is caused by shifting tectonic plates, which can split the ground apart. Floods occur when heavy rain or snowmelt causes rivers to overflow their banks. Tsunamis are large waves caused by undersea earthquakes or landslides. Cyclones are powerful rotating storms with strong winds. Case studies describe specific natural disasters including the 2004 Indian Ocean earthquake and tsunami that killed over 200,000 people across several countries.
The document summarizes information about earthquakes that have occurred in different locations. It discusses some key facts about earthquakes globally, including that 100,000 are felt each year and 100 cause damage annually. It then provides details about the largest earthquake in Japan in 2011 with a magnitude of 9.0 that caused a devastating tsunami, resulting in over 10,000 casualties. It also discusses the strongest earthquake to hit the Philippines, which was a 7.9 magnitude quake in 1990 in Baguio City that killed over 1,600 people.
The document summarizes the 2013 Himalayan tsunami that caused devastating floods and landslides in the Indian state of Uttarakhand from June 14-17. It describes how unusually heavy rainfall of over 375% of the normal amount, combined with other factors like construction, tourism development, and climate change, led to flash floods and landslides that caused widespread destruction and over 10,000 deaths. It discusses the emergency response and relief efforts by government agencies and militaries to conduct search, rescue and evacuation operations in the difficult terrain. It concludes that while heavy rainfall triggered the natural disaster, human activities like infrastructure development contributed greatly to its large scale impacts.
The document discusses the design of water distribution systems. It states that the design must satisfy water needs and maintain minimum residual pressures. It discusses pressure variations and velocity limits in distribution systems. It introduces the Hazen-Williams equation for calculating head loss in pipes based on flow rate, length, diameter and roughness coefficient. The document outlines Hardy's Cross Method for balancing flows in distribution networks using loop equations. It provides an example of applying the method to calculate pipe diameters and flows in a sample network.
The document contains information to estimate water requirements for different communities including design population, per capita demand, average water demand, maximum daily demand, peak hourly demand, and fire flow requirements. It provides the calculations to estimate the total water requirement considering both regular demand and fire demand for communities with populations of 22,000, 55,000 and 120,000. Fire flow rates and daily amounts are also estimated for different building types and floor areas.
The document summarizes the history of pavement development from ancient times to modern roads. It describes how ancient human pathways evolved into animal tracks and then wheeled vehicles required harder road surfaces. The Romans constructed extensive road networks with gravel surfaces. Later, the French developed roads using compacted stone layers, while the British engineer Macadam introduced using broken stone layers which was more economical. Modern roads now use bituminous concrete and cement concretes, and employ new construction technologies.
This document discusses roads in Pakistan, including CPEC roads, motorways, and national highways. It provides details on 5 CPEC road projects costing over $5 billion that are planned or under construction. It also lists 14 existing and under construction motorways running over 5,000 km, as well as over 20 national highways spanning the country and totaling nearly 20,000 km. The motorways and national highways facilitate domestic and international transportation across Pakistan.
Highway engineering involves planning, designing, constructing, operating, and maintaining roads and bridges. A highway connects towns and cities via intersections and traffic lights, while a motorway connects important cities at higher speeds without intersections. The history of paved roads dates back to ancient Egypt and the Roman Empire, while modern highway construction began in the 20th century. There are two main types of pavements: flexible pavements made of asphalt layers over granular material, and rigid concrete pavements that distribute loads over a wide area.
The document discusses China-Pakistan Economic Corridor (CPEC) roads network, including motorways and national highways. It outlines 15 major CPEC road projects that are either under construction or planned. These include expanding the Karakoram Highway, upgrading the Peshawar-Karachi motorway, and reconstructing the ML-1 rail line from Peshawar to Karachi. CPEC aims to boost regional connectivity and benefit not just China and Pakistan but also other countries through increased trade and economic cooperation.

Recursive Approach
What is an algorithm?
An Algorithm is a procedure to solve a particular problem in a finite number of steps for a finite-sized input.
The algorithms can be classified in various ways. They are:
Implementation Method
Design Method
Design Approaches
Other Classifications
In this article, the different algorithms in each classification method are discussed.
The classification of algorithms is important for several reasons:
Organization: Algorithms can be very complex and by classifying them, it becomes easier to organize, understand, and compare different algorithms.
Problem Solving: Different problems require different algorithms, and by having a classification, it can help identify the best algorithm for a particular problem.
Performance Comparison: By classifying algorithms, it is possible to compare their performance in terms of time and space complexity, making it easier to choose the best algorithm for a particular use case.
Reusability: By classifying algorithms, it becomes easier to re-use existing algorithms for similar problems, thereby reducing development time and improving efficiency.
Research: Classifying algorithms is essential for research and development in computer science, as it helps to identify new algorithms and improve existing ones.
Overall, the classification of algorithms plays a crucial role in computer science and helps to improve the efficiency and effectiveness of solving problems.
Classification by Implementation Method: There are primarily three main categories into which an algorithm can be named in this type of classification. They are:
Recursion or Iteration: A recursive algorithm is an algorithm which calls itself again and again until a base condition is achieved whereas iterative algorithms use loops and/or data structures like stacks, queues to solve any problem. Every recursive solution can be implemented as an iterative solution and vice versa.
Example: The Tower of Hanoi is implemented in a recursive fashion while Stock Span problem is implemented iteratively.
Exact or Approximate: Algorithms that are capable of finding an optimal solution for any problem are known as the exact algorithm. For all those problems, where it is not possible to find the most optimized solution, an approximation algorithm is used. Approximate algorithms are the type of algorithms that find the result as an average outcome of sub outcomes to a problem.
Example: For NP-Hard Problems, approximation algorithms are used. Sorting algorithms are the exact algorithms.
Serial or Parallel or Distributed Algorithms: In serial algorithms, one instruction is executed at a time while parallel algorithms are those in which we divide the problem into subproblems and execute them on different processors.
INVESTIGATION OF PUEA IN COGNITIVE RADIO NETWORKS USING ENERGY DETECTION IN D...csijjournal
?
Primary User Emulation Attack (PUEA) is one of the major threats to the spectrum sensing in cognitive
radio networks. This paper studies the PUEA using energy detection that is based on the energy of the
received signal. It discusses the impact of increasing the number of attackers on the performance of
secondary user. Moreover, studying how the malicious user can emulate the Primary User (PU) signal is
made. This is the first analytical method to study PUEA under a different number of attackers. The
detection of the PUEA increases with increasing the number of attackers and decreases when changing the
channel from lognormal to Rayleigh fading.
