This document studied the effect of limewater on the properties of cement mixtures containing silica fume. Tests were conducted on cement mixtures with 0-50% replacement of cement with silica fume, and mixing with either water or saturated limewater. Using limewater increased both initial and final setting times compared to water. Compressive strength, tensile strength, and flexural strength were highest with 30% silica fume replacement and limewater mixing, showing increases of 34.7%, 60.96%, and 46.91% respectively over the control mixture without silica fume or limewater at 28 days. In conclusion, limewater improved the mechanical properties of cement mixtures with 30% silica fume replacement.
Study of Concrete by Replacing Fine Aggregate by ETP Sludge of TiO2IJERA Editor
The rapid increase in construction activities leads to scarcity of conventional construction materials such as
cement, fine aggregate and coarse aggregate. Researches are being conducted for finding cheaper materials. In
India, there are many industries producing large amount of effluent treatment plant waste sludge which leads in
problems of disposal. The final destination of effluent treatment plant sludge affects the environment. So
alternative option is necessary for disposing effluent treatment sludge. In this study is subjected to the effective
reuse of effluent treatment plant sludge of TiO2 pigment generated from Kerala Minerals and Metals Ltd
(KMML). The aim of the thesis is to determine the strength parameters of concrete with the partial replacement
of fine aggregate by waste sludge from KMML. Reuse of ETP sludge in concrete is an effective option for the
problem of ultimate disposal up to greater extent. In this study the fine aggregate is replaced by the ETP sludge
of TiO2 with different percentages such as 5%, 10%, 15%, 20%, and 25% in M35 concrete mix. The various tests
such as compression, tensile and flexural strength are conducted.

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.
Water scarcity is the lack of fresh water resources to meet the standard water demand. There are two type of water scarcity. One is physical. The other is economic water scarcity.

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.
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.
