Tension members can fail due to three modes:
1. Gross section yielding, where the entire cross-section yields
2. Net section yielding, where the reduced cross-section after subtracting holes yields
3. Block shear failure, which also occurs in welded connections along planes of shear and tension
The design strength is the minimum of the strengths from these three failure modes. Block shear is demonstrated using a failed gusset plate connection with failure planes around the weld. The problem determines the tensile strength of a plate connected to a gusset plate, calculating the strength based on gross section yielding, net section yielding, and block shear failure.

It does not offer resistance against rotation and also termed as a hinged or pinned connections.
It transfers only axial or shear forces and it is not designed for moment
It is generally connected by single bolt/rivet and therefore full rotation is allowed

Stiffness method of structural analysisKaran Patel
This method is a powerful tool for analyzing indeterminate structures. One of its advantages over the flexibility method is that it is conducive to computer programming.
Stiffness method the unknowns are the joint displacements in the structure, which are automatically specified.
Here we discussed about the balanced section,Under reinforced and Over reinforced sections and what are the failure and their moment of resistance.. and also comparison between among three sections

Design aids for tension members as per revised is 800 2007eSAT Journals
Abstract The B.I.S. recently revised the new IS: 800-2007 . This is based on limit state method. This new code includes variety in elements like tension members, compression members , flexural members, combined connection, combined axial and bending design of members. The B.I.S. has yet not published any design aids based on new IS: 800-2007. For saving time in various design of structural steel section, one need to have their own computer programme or design aids or spreadsheet which is based on IS: 800-2007. In this research we have developed excel programme spreadsheet to analyze & design tension members, which will help the structural designer to save their time in designs. Also we have prepared design aids to find out the capacity on angled tension member with single row of bolts connected to the gusset plate.

Investigation into the Effects of Variable Row Spacing in Bolted Timber Conne...Caleb Knudson
The effects of variable row spacing in single-shear bolted timber connections subjected to reverse cyclic loading have been determined through this experimental research. A variety of performance characteristics including 5% offset yield strength, capacity and ductility have been examined for tested connections as row spacing varied; their results are addressed herein. Statistical analyses were conducted to determine whether inferences could be made regarding mean values for the ductility ratio, 5% offset yield strength and capacity of tested multiple-bolt connections, as row spacing was increased from 2D to 3D.
Bolted connections utilizing three different bolt diameters, four unique connection geometries, and variable row spacing within each connection geometry, were subjected to a displacement controlled loading protocol. The protocol used, which was developed by the CUREE-Caltech Wood frame Project is representative of natural hazard loading. Connections were fabricated in order to achieve specific yield modes based on predictions of the Yield Limit Model in order to determine the validity of this model as row spacing was varied.
The primary conclusion drawn from the results of this research addresses the current design recommendation for row spacing in bolted timber connections. The 2001 NDS (AF&PA, 2001) states within the provisions of the Geometry factor (C ) that the minimum row spacing in bolted connections shall be 1.5D. This provision should first, be modified to require minimum row spacing for full design value of 3D. Additionally, a linear reduction should be applied in the same manner as current NDS reductions for end distance and bolt spacing, with minimum row spacing for reduced design value of 1.5D.
The predictions provided by the Yield Model were, in many cases, inaccurate. Several factors unaccounted for in the model including end fixity caused by the nut and washer, sliding friction between the members, and bolt tensioning, greatly influence connection yield behavior. The derivation of the model should be expanded to include these factors.
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.
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.
