This document analyzes the effect of shear wall position in a 10-story building through time history and response spectrum analysis. 10 different models are analyzed with the shear wall located at the top, center, or bottom of floors 6m, 9m, and 12m. Results show the model with a shear wall at the center of floor 6m performs best in minimizing displacements, reactions, and moments under seismic loading compared to other models and the normal frame structure without a shear wall. Steel quantities also tend to be lower for this optimal shear wall configuration.

Seismic performance of r c buildings on sloping grounds with different types ...eSAT Journals
Abstract
Structure are highly susceptible to serve damages in earthquake scenario, so choosing an appropriate lateral force resisting
bracing systems will have a significant effect on performance of the structure. So this present study is aimed at evaluating and
comparing various types of eccentric steel bracings for 12 storey RC frame building resisting on sloping ground configurations.
For this 5 types of bracing systems like X-Bracing, Diagonal bracing, K- bracing, V-bracing and inverted V bracing are
considered on the outer periphery of the buildings with step back and set back – step back type configurations are modeled and
analyzed. The models are compared for different aspects within the structure, such as the maximum storey displacement, base
shear, storey drift and storey shear, the structure is analyzed for seismic zone V and medium soil condition as per IS 1893:2002
using ETABS software. Results conclude that on sloping ground due to irregularity on ground surface, the structures are more
vulnerable to earthquakes. Hence use of eccentric steel bracing is an effective and economical way to resist earthquake forces,
Inverted V type bracing performs well compared to other bracing types. By using inverted V type bracing in step back buildings
types maximum storey displacement of 70% and storey drift of 66% are obtained. Similarly for setback – step back configuration
maximum storey displacement of 74% and storey drift of 70% are obtained respectively.

The optimum location of shear wall in high rise r.c bulidings under lateral l...eSAT Journals
Abstract Shear walls are the structural elements of the horizontal force resisting system .shear walls have high influence stiffness and strength and provided to resist gravity loads as well as lateral loads caused by seismic and wind. So many literatures are available to analyze and design of shear wall. However the optimum location and its effects in high rise r.c.buildings is not much discussed in any literatures. In this paper the main aim is to find the effective, efficient, and optimum location of shear walls in high rise irregular R.C building. In this present study the optimum location of shear wall has been investigated with the help of three different models. Model 1 is bare frame structural system and other two models are dual type structural system with central core wall and corner shear wall. An earthquake load is calculated as per IS 1893(PART-1)-2002 and applied to (G+20) storey R.C building in zone-2 and zone-5. The analysis is performed using ETABS 9.7.4 Software package.

Influence of Modeling Masonry Infill on Seismic Performance of Multi-Storeyed...ijsrd.com
Masonry infilled RC frames are the most common type of structures used for multi-storeyed constructions in the developing countries, even in those which are located in seismically active regions also. Masonry infill walls are mainly used to increase the stiffness and strength of R C framed buildings. R C framed building with open first storey is known as soft storey, which performs poorly during earthquakes. A similar soft storey effect can also appear top storey level if it is used as service storey. The soft storey located in the upper part of the multistorey building does not significantly affect. To observe the effect of masonry infill panel, it is modeled as an equivalent double diagonal strut. In this study 7 models are taken were analyzed with two different techniques of modelling of masonry infill wall with L type of shear wall when subjected to earthquake loading. The results of masonry infill show more stiffness than the strut modeling technique. It is observed that, providing infill wall and shear wall improves earthquake resistant behavior of the structure and also the effect of water pressure, an attempt is made to develop relationship between strength and stiffness ratios for linear trend line.

Abstract
From past earthquakes it is proved that many of structure are totally or partially damaged due to earthquake. So, it is necessary to determine seismic responses of such buildings. There are different techniques of seismic analysis of structure. Time history analysis is one of the important techniques for structural seismic analysis generally the evaluated structural response is non-linear in nature. For such type of analysis, a representative earthquake time history is required. In this project work seismic analysis of RCC buildings with mass irregularity at different floor level are carried out. Here for analysis different time histories have been used. This paper highlights the effect of mass irregularity on different floor in RCC buildings with time history and analysis is done by using ETABS software.

Seismic pounding between adjacent rc buildings with and without base isolatio...eSAT Journals
Abstract Among the possible structural damages during an earthquake, the seismic induced pounding also has been one of the commonly observed phenomena. This is because the separation gap between many adjacent buildings is inadequate to accommodate the relative motions, so buildings vibrate out of phase and collides. Despite the fact that the seismic pounding between nearby structures is considered in the codal procurements, the act of development is still an issue in numerous metropolitan zones where the structures are built with no adequate partition separation which brings about their pounding. In this study E-Tabs nonlinear software is used for simulation of adjacent multi-storeyed RC frame buildings of G+14 and G+9 storey, the provisions that may reduce the effects of pounding like the separation distance, addition of shear walls, lateral bracings and variation in storey height of the buildings have been considered for analysis. And the responses like storey-displacement and pounding force by considering both fixed base and base-isolated conditions are arrived. Keywords: Seismic pounding, RC frame building, Separation distance, Gap elements, Storey-displacement Pounding force, Fixed-base, Base isolation.

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.
