The document contains several word problems involving ratios and proportions. Some examples include:
- The ratio of boys to girls in a college originally being 5:3 and changing to 9:7 after boys and girls leave and join.
- Salaries of two people originally being in a 4:3 ratio and changing to a 40:57 ratio after raises of differing amounts.
- Incomes and expenditures of two people originally being in given ratios and calculating their total incomes if each saves a given amount.
- Numbers of employees in different departments of a company with given ratios and percentages changing various values.
The problems require setting up and solving equations to determine unknown values from the initial ratios and changes provided.
the world of technology, AI robots are leading the way with their ability to think and learn like humans. They have the potential to revolutionize our lives, work, and how we interact with the world.
From making things in factories to helping doctors in hospitals, AI robots can do many tasks on their own. They can make processes faster, more efficient, and open up new opportunities.
In this article, we will explore the amazing potential of AI robots and introduce you to 7 currently making waves around the world.
What is an AI robot?
An AI robot is a type of robot that is designed to perform tasks or interact with humans using artificial intelligence (AI) technology.
It combines physical hardware, such as sensors, motors, and manipulators, with advanced software algorithms that enable it to perceive and understand its environment, make decisions, and take actions autonomously or with minimal human intervention.
The AI component allows the robot to learn from its experiences, adapt to different situations, and improve its performance over time.
AI robots can be used in various fields, such as manufacturing, healthcare, transportation, and even in our homes as personal assistants or companions.

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.
Sachpazis:Terzaghi Bearing Capacity Estimation in simple terms with Calculati...Dr.Costas Sachpazis
Terzaghi's soil bearing capacity theory, developed by Karl Terzaghi, is a fundamental principle in geotechnical engineering used to determine the bearing capacity of shallow foundations. This theory provides a method to calculate the ultimate bearing capacity of soil, which is the maximum load per unit area that the soil can support without undergoing shear failure. The Calculation HTML Code included.

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.
