This document summarizes a study on soil stabilization using bone ash and silica fume. The study investigated how adding these materials affected key engineering properties of clayey soil. Tests found that adding up to 6% bone ash and 20% silica fume increased the soil's maximum dry density, CBR value, and unconfined compressive strength, while decreasing the liquid limit and increasing the plastic limit. The results indicate that bone ash and silica fume can effectively improve the engineering behavior of expansive clayey soils when used as additives.

Effect of saw dust ash and fly ash on stability of expansive soileSAT Journals
Abstract This study is focused on evaluating the effects of saw dust ash and fly ash on properties of laterite soil. These soils tend to have low shear strength and further it may lose shear strength in presence of moisture. This undesirable engineering property of the soil may cause potential natural hazard. These soils are plastic, compressible and expansive in nature which has the tendency to swell in presence of moisture and shrink in dried condition. Fly ash and saw dust ash which are disposed materials from industries are used in the stabilization process to improve the properties of soil. Fly ash is a cementatious material which reduces the swell of the soil when added in proper proportion. Saw dust ash by itself has a little cementatious property in addition with the presence of moisture it influences to the strength and compressibility characteristics of soil. The tests that are carried out on the natural soil sample are specific gravity, consistency limits, CBR, compaction, UCC and differential swell index. Further these tests were carried out on stabilized state of soil by adding 5, 10, and 15 of fly ash and saw dust ash. The results gives the effect of fly ash and saw dust ash on geotechnical properties of laterite soil. Keywords: FA-Fly Ash, SDA-Sawdust Ash, Stabilization, CBR-California Bearing Ratio, UCC-Unconfined Compression Test

Effect of partial replacement of natural sand with crushed sand along with su...eSAT Journals
Abstract
The effect of partial replacement of natural sand (NS) by crushed sand (CS) and partial replacement of cement by supplementary cementing material have been investigated. All the trials have been taken at actual construction site and tested at site laboratory. Supplementary Cementing materials (SCM) Fly Ash and GGBS have been used and cement has been replaced by three combination of Fly ash (15%, 20%, 25%) and two combinations of GGBS (40% & 50%). In both the cases , 50% natural sand have been replaced by crushed sand .Both the materials have shown good compatible results when used and it is found that use of SCM gives better result in terms of compressive strength and workability due to reduction in w/c ratio. This paper puts forward the applications of crushed sand and supplementary cementing materials as an attempt towards sustainable development. It will help to find viable solution to the declining availability of natural sand to make eco-balance.
Keywords: Crushed Sand (CS), Natural Sand (NS), Fly Ash (FA), Ground Granulated Blast Furnace Slag (GGBS), Admixture.
The need for efficient and better construction methods and materials is increasing day by day due to the rapid urbanization taking place around the globe at the same time it is our responsibility to make sure that the application of materials involved in the construction does not create adverse environmental impacts. In this research an attempt to review the optimization of the material usage of a hollow core in Reinforced concrete (RC) flexural members in the zone of tension. This shall facilitate the reduction of the dead loads which is an important factor with respect to seismic effect on structures. This paper studies the research works carried out on RC hollow beams in order to understand the flexural behaviour compared with the conventional solid beams.

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.
Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.
