This document discusses the torsional response of irregular buildings under seismic loading. It begins with an abstract that outlines the purpose of studying how irregular structures respond to torsional loads caused by earthquakes. Several methods of seismic analysis are then described. The concept of torsional irregularity is defined according to building codes. Previous studies on the torsional response of irregular structures are summarized, finding increased seismic demand and sensitivity for structures with irregular plans or vertical setbacks. The conclusion is that structural irregularities can significantly reduce seismic performance by increasing torsional forces, and proper design is needed to control torsion effects in irregular structures.
Seismic Evaluation of Multi-storeyed Buildings On Plain Ground And Curve Slop...IJSRD
Most of the hilly regions of India are highly seismic. Buildings on hill slopes differ in a way from other buildings. The soft storeies are typical feature in modern constructions specially in seismic areas which has been experience by the previous studies and past earthquakes. Due to verious type of structures on sloped ground structures are comes under irregularity and asymmetricity. Structures on slope leads to seismic cases.The damages to the structures are determined and acceptable safety can be provided. The linear-elastic analysis is not adequate in highly seismic areas. Thus for the design of building in seimic areas and sloped areas inelastic procedure is used. In the present dissertation work, 3D analytical model of eleven storeyed buildings on plain and curved ground have been generated. Models are analyze using ‘‘ETABSâ€Âto get the behavior of structure due to change in column height in ground story due to curved sloped ground. The analytical model of the building includes all important components that influence the mass, strength, stiffness and deformability of the structure. To study the effect of infill, concrete shear wall and concrete core wall during earthquake, seismic analysis using both elastic and inelastic method of analyses i.e., linear static (equivalent static method), linear dynamic (response spectrum method) has been performed. The deflections at each storey level has been compared by performing equivalent static method, response spectrum method. Storey drifts are within the permissible limit given for linear static and linear dynamic method. Again contrary to common practice, the presence of masonry infills, concrete shear and concrete core wall may affect the overall behavior of structure while subjected to earthquake forces.

The structural system of a high-rise building often has a more pronounced effect than a low rise building on the
total building cost and the architecture aspect of building. Shear walls are lateral load resisting structural
systems which provide stability to structures from lateral loads like wind and seismic Loads. The design of multi
storey building is to have good lateral load resisting System along with gravity load system for safety of
occupant and for better performance of structure even in most adverse condition. The main scope of this project
is to apply class room knowledge in the real world by designing a multi-storied residential building. Shear walls
are more efficient in resisting lateral loads in multi storied buildings. Steel and reinforced concrete shear walls
are kept in major positions of multi storied buildings which are made in consideration of seismic forces and
wind forces. To solve this purpose shear walls are a very powerful structural elements, if used judiciously can
reduce deflections and stresses to a very great extent. Our project contains a brief description of building with
shear wall and without shear wall thoroughly discussed structural analysis of a building to explain the
application of shear wall. The design analysis of the multi storied building in our project is done through
STAAD-PRO, most popular structural engineering software. It is featured with some ultimate power tool,
analysis and design facilities which make it more users friendly.

PERFORMANCE BASED ANALYSIS OF VERTICALLY IRREGULAR STRUCTURE UNDER VARIOUS SE...Ijripublishers Ijri
In the recent years a lot of attention has been given to the earthquake analysis of structure it is one of the most devastating
natural calamity and which causes severe damage not only to the properties but also to the lives. This is the
reason there has been a lot of focus on the structures to be earthquake resistant. Buildings get damaged mostly due
to the earthquake ground motions. In an earthquake, the building base experiences high frequency movements, which
results in the inertial force on the building and its components and this problem gets worse when a structure is irregular
in shape, size etc,. Therefore, there is a lot to work on the seismic behavior of the irregular building which might not
respond the way regular building does. It makes the irregular building quite more complex and unpredictable during
the course of an earthquake.

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.
Keywords: X-Bracing, Diagonal Bracing, K- Bracing, V-Bracing and Inverted V Bracing
In the present report, at present scenario many buildings are asymmetric in elevation based on the
distribution of mass and stiffness along each storey throughout the height of the building. Most recent
earthquakes have shown that the irregular distribution of mass, stiffness and strengths may cause serious damage
in structural systems. This project performance of the torsionally balanced and torsionally unbalanced buildings
also called as symmetric and asymmetric buildings by subjecting to response-spectrum analysis. The buildings
have un-symmetrical distribution of vertical irregularinstorey’s. In this project the effort is made to study the
effect of eccentricity between centre of mass (CM) and centre of stiffness (CR) on the performance of the
buildings. Three buildings (G+3), (G+6) & (G+9) models are considered for study, which are constructed on
medium soil in seismic zone II of India (as per IS:1893-2002), one symmetric and asymmetric in vertical
irregular distribution. The performance of a multi-storey framed building during sturdy earthquake motions
depends on the distribution of mass, stiffness, and strength in both the horizontal and vertical planes of the
building. In some cases, these weaknesses may be produced by discontinuities in stiffness, strength or mass
between adjoining storeys. Such discontinuities between storeys are often allied with sudden variations in the
frame geometry along the height.

Abstract
Earthquakes are one of the most life threatening, environmental hazardous and destructive natural phenomenons that causes
shaking of ground. This result in damage to the structures, hence we need to design the buildings to withstand these earthquakes
which may occur at least once in the life time of the structure. Structures possess less stiffness and strength in case of irregular
configured frames; to enhance this, lateral load resisting systems are introduced into the frames. In this study, G+5 storey
building model has been analyzed considering different types of vertical geometric irregularities and steel bracings using
pushover analysis with the help of ETABS 9.7 software. Addition of X type brace, V type Brace and Inverted V/K type brace shows
that use of X-type of bracing is found more suitable to enhance the performance of the irregular buildings.
Key Words: pushover analysis, vertical irregularity, steel bracings, performance point.

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.
