This document summarizes a study analyzing the rear under-run protection device (RUPD) on trucks through non-linear quasi-static finite element analysis. RUPDs are designed to prevent passenger vehicles from going under trucks in rear impacts. The study develops a finite element model of an RUPD and subjects it to loading conditions specified in standards to evaluate its strength. The results, such as effective plastic strain, are compared to material properties to check if the RUPD meets strength requirements. The analysis aims to optimize RUPD design through finite element modeling and simulation of the standardized testing procedure.
Design and Optimization of Front Underrun Protection DeviceIOSR Journals
Front Under run Protection Device is tested for car occupant safety by performing Crash analysis
with 800 kg (mass of the car) hitting the Front Underrun Protection Device with certain velocity and analyzing
its performance and changing design to improve the crash results. Optimization is carried out to improve the
crash results for safety of passenger. To reduce number of iterations during the development process, the
computational simulation method is used in Front Underrun Protection Device analysis for impact loading. An
explicit finite element code like LS Dyna is used for the simulation. This paper explains the FE analysis of Front
Underrun Protection Device for impact loading. All the results obtained from the CAE analysis are evaluated
against the requirements of IS 14812-2005 which could reduce the process development time and cost.

Abstract
When passenger car hits the truck-trailer at rear, it penetrates inside the truck bed called truck trailer under-ride crash. This is responsible for thousands of accidents, causing severe injuries and spot death. This is mostly due to the lack of effective guards. The Present work focuses on energy absorption analysis of a Rear under Run Protection Device (RUPD) under crash scenario. The aim of the study is to replace Steel RUPD with RUPD made of composite material to reduce weight of the vehicle. In this study carbon fibre reinforced plastic composites were selected due to their high specific strength and specific stiffness which make them a preferred candidate in the material selection for modern lightweight structures in automotive engineering which can contribute to the improvement of mileage in addition to safety of the occupants. The RUPD was modelled in CATIA. Finite element model was generated in HYPERMESH and analysed in LS-DYNA for both Carbon/Epoxy RUPD and Steel RUPD and observed that Carbon/Epoxy RUPD absorbs 50% of kinetic energy; whereas steel RUPD absorbs 90%. But weight of Steel RUPD is 75 kg whereas the weight of Carbon/Epoxy RUPD is less than Steel RUPD which found to be below 15 kg. This results in weight reduction and increases mileage of the vehicle. Considering above advantage, composites can be potential candidate for RUPD.

Design and Enhancement of Rear Under-Run Protection Device For 15 Tonne Capac...paperpublications3
Abstract: The heavy commercial vehicles are equipped with under-run protection devices (UPD) to enhance safety of occupants in small vehicles in the event of under-run. These UPD are popularly classified as RUPD (rear under-run protection devices), SUPD (side under-run protection devices), and FUPD (front under-run protection devices). These devices primarily work to improve safety of smaller vehicles by changing its interaction with heavy vehicles thereby resulting in change in small vehicle structural engagement for energy absorption. Without UPD, smaller vehicle passenger compartment is likely to interact with stiff commercial vehicle chassis frame structures.

Under-running of passenger vehicles is one of the important parameters to be considered during
design and development of truck chassis. Front Under-run Protection Device (FUPD) plays an important role
in avoiding under-running of vehicles from front side of a truck. An explicit finite element software Altair
Radio's is used in FUPD analysis for impact loading. The deformation of FUPD bar and plastic strains in
FUPD components are determined in the impact analysis for predicting failure of the system to meet the
compliance requirements as per IS 14812-2005. Additionally, failure analysis of the FUPD attachment points
with chassis is determined. Physical testing can be reduced significantly with this approach which ultimately
reduces the total cycle time as well as the cost involved in product development.

Quality defects in TMT Bars, Possible causes and Potential Solutions.PrashantGoswami42
Maintaining high-quality standards in the production of TMT bars is crucial for ensuring structural integrity in construction. Addressing common defects through careful monitoring, standardized processes, and advanced technology can significantly improve the quality of TMT bars. Continuous training and adherence to quality control measures will also play a pivotal role in minimizing these defects.
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.
