Behavior of RC Beams Retrofitted/Strengthened With External Post-Tension SystemINFOGAIN PUBLICATION
This paper presents a study on the flexural behavior of strengthened RC beams using external post-tensioning technique under the effect of cyclic loads. Post tensioning techniques is a new method to improve the behavior of cracked and sound beams. This new technique was used in this research to improve the behavior of cracked and un-cracked beams. The study consists of two stages, the first stage is an experimental program which is carried out in lap to test casted beams, and the second stage is a theoretical program which was carried out to verify the results of experimental program. The behavior of RC beams in different levels of cracks was studied, crack pattern was observed and failure type was recorded. Comparisons between the behaviors of different RC beams were performed. The experimental study included using of prestressing steel bars, GFRP bars and the effect of different percentage of shear reinforcement was also taken into consideration. Specimens were tested under the effect of cyclic load. Finally the simulations of tested beams were modeled in finite element software (ANSYS) to verify the results of experimental work compared to theoretical analysis.
EXPERIMENTAL INVESTIGATION OF REINFORCEMENT COUPLERS AS REPLACEMENT OF BENT BARrk pandey
In reinforced concrete structures, it is essential to enhance the performance of
beam–column joints in moderate and severe seismic susceptibility areas. An attempt has
been made to study and evaluate the performance of exterior beam–column joint using
proper reinforcement anchorage and joint core detail. The anchorages are detailed as per
ACI-352 (Mechanical anchorage), ACI-318 (900Standard bent anchorages) and IS-456 along
with confinement as per IS-13920. Significant improvements were observed in seismic
performance, ductility and strength while using stirrups bar in combination with mechanical
anchorage detail for higher seismic prone areas, apart from resolution to reducing
congestion of reinforcement in joint core. To assess the performances of anchorages and
joint details, three groups of three specimens each were tested under monolithic loading.
The test results are evaluated and presented in this paper.
EXPERIMENTAL STUDY OF RETROFITTED RC BEAMS USING FRPAM Publications
In order to improve the performance of reinforced cement concrete structure (RCC) it is better to repair or upgrade the structure by retrofitting. Retrofitting is one of the best options to make an existing inadequate building safe against future probable earthquake or other environmental forces. Retrofitting is the modification of existing structure to make them more resistance to seismic action, motion of ground and failure of soil due to earthquake or other natural calamities such as tornadoes cyclones and winds with high velocity caused by thunder storm, snow fall, hailstorms, etc. The study investigate the improvements in the structural behaviour of the RC beams retrofitted with various types of FRP such as glass fibres, coir fibres, banana fibres, jute fibres and cotton fibres. The experimental programme includes strengthening and flexural strength test of 18 simply supported RC beams of 500x100x100 mm. The test results showed an increase in ultimate load for the retrofitted beam when compared to normal control beam and corresponding increase in the value of modulus of rupture. The retrofitted beams with glass fibre using epoxy as binder having 47.32% more strength than the control beams. Area under load-deflection curve gives toughness. Toughness value is found to be more in RC beams retrofitted with banana fibre.

15 experimental study for strengthening of rc rectangular columns with anchor...Ahmed Ebid
Debonding between CFRP sheets and concrete surface is one of the most important modes of failure. The common solution to
prevent this mode of failure is to extend the CFRP sheets by enough length to avoid debonding. A more advanced technique is to anchor the CFRP sheets to the concrete element using either steel or CFRP anchors. The aim of this research is to study the effect of using CFRP anchors on the capacity of concentric and eccentric RC columns. In order to achieve that goal, ten specimens of RC columns divided into two sets were tested. The first set was tested under concentric load, while the other set was tested under eccentric load. Each set had one control sample, while the other four samples were wrapped with CFRP bands. Two of the wrapped samples were anchored and the others were not. The spacing between CFRP wraps was varied between 80 and 200 mm. The results showed that the concentric and eccentric capacity of the sample increased with decreasing the spacing between CFRP bands as long as the eccentricity is small enough to cause
compression failure mode. But for samples with tension failure caused by large eccentricity, the CFRP bands have no effect on the capacity. It was also noted that anchors have no significant effect on the axial capacity of the samples

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.

Courier management system project report.pdfKamal Acharya
It is now-a-days very important for the people to send or receive articles like imported furniture, electronic items, gifts, business goods and the like. People depend vastly on different transport systems which mostly use the manual way of receiving and delivering the articles. There is no way to track the articles till they are received and there is no way to let the customer know what happened in transit, once he booked some articles. In such a situation, we need a system which completely computerizes the cargo activities including time to time tracking of the articles sent. This need is fulfilled by Courier Management System software which is online software for the cargo management people that enables them to receive the goods from a source and send them to a required destination and track their status from time to time.

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.
