This document describes a parametric study on the behavior of reinforced concrete box culverts under dynamic loading. It discusses the modeling and analysis of a box culvert bridge using STAAD.Pro software. The design loads considered are per IRC 6. The document provides details of the hydraulic calculations and design of the box culvert, including the discharge calculation, dimensions of the culvert, and loading cases analyzed. It analyzes three cases: when the top slab carries dead and live loads and the culvert is empty, when it carries both loads and is full, and when the slab does not carry live loads and it is full.

The research paper aims to replicate the wind tunnel test of General Motors pick-up truck using CFD analysis. The pickup is a blunt body and simulation reveals vortex shedding from the edges of the vehicle downstream. The unsteadiness of this phenomenon is seen in the oscillation of residue. The paper shows matching of velocity magnitude downstream of the vortex. Authors - Bahram Khalighi (GM, USA), Basant Gupta et al Zeus Numerix.
As catastrophic bridge collapse accidents not only cause significant loss of property, but also have a severe social impact. Therefore, the structural health monitoring of bridges for damage detection by vibration analysis gets more attention. Reinforced concrete bridges are the most common and extended structures present in the worldwide. These structures are often characterized by Piers, Abutments, deck slabs. This paper looks on the work of modelling and analysis of bridge in STAAD.Pro software, and the specific bridge model is taken of a particular span. It is subjected to vary Young’s modulus (E) in the mid span of bridge deck slab to induce damage in order to obtain maximum bending moment, as the structural strength reduces. From the analysis Mu/bd2 values from SP 16 code is used to identify the damage on the bridge deck slab, then natural frequency of the bridge, mode shapes, variation of the deflection and node displacements of bridge deck slab under the action of static and dynamic load at different aspect ratios with original design parameters and at failure is carried out in this project.
ANALYSIS AND COMPARATIVE STUDY OF COMPOSITE BRIDGE GIRDERSIAEME Publication
The composite bridge gives the maximum strength in comparison to other bridges. The design and analysis of various girders for steel and concrete by using various software, in that paper for composite bridge calculate the bending moment for T girder and finding which is more effective. The efforts will make to carry out to check the analysis of bridge by using SAP 2000 software. To determine the static analysis of T girder by using manual method as well as software. The results obtained from the software in structural analysis are compare the results obtained from manual calculations.

water table. This paper dealt with the rehabilitation of basement RCC raft foundation considering various design
aspects like uplift due to ground water table, sub-soil properties and restriction on depth of raft to suffice
available headroom for intended use.
Analysis of rc bridge decks for selected national a nd internationalstandard ...eSAT Journals
Abstract
The paper presents the comparison of the effect of different standard loadings on a set of reinforced concrete bridge decks using the
finite-element method. The parameters investigated include the aspect ratio (span/width) and type of loading. The investigations are
conducted on two lane slab bridge decks of span 5m to 9.5m and two lane T beam bridge decks of span 7.5m to 20m. A total of 36
bridge models were analyzed. The variation of different critical structural response parameters such as deflection, longitudinal
bending moment, transverse moment, shear force and torsional moments are evaluated for IRC loading (IRC Class A and 70R
loadings), AASHTO loading (HL93) and Euro standard loading (LM1). The results shows that the maximum difference in deflection
and longitudinal bending moment for the two IRC standard loading ranges from 5 to 15%. While the difference between
corresponding values for the AASHTO loading in the range of 5 to 17%. The maximum axle load of euro standard loading is found to
be 2.2 times higher than IRC class A loading maximum axle load hence the values of structural response parameters are increased by
1.7 to 1.8 times. Therefore there is a need for adopting simplified and more realistic standard loads in the future.

Online aptitude test management system project report.pdfKamal Acharya
The purpose of on-line aptitude test system is to take online test in an efficient manner and no time wasting for checking the paper. The main objective of on-line aptitude test system is to efficiently evaluate the candidate thoroughly through a fully automated system that not only saves lot of time but also gives fast results. For students they give papers according to their convenience and time and there is no need of using extra thing like paper, pen etc. This can be used in educational institutions as well as in corporate world. Can be used anywhere any time as it is a web based application (user Location doesn’t matter). No restriction that examiner has to be present when the candidate takes the test.
Every time when lecturers/professors need to conduct examinations they have to sit down think about the questions and then create a whole new set of questions for each and every exam. In some cases the professor may want to give an open book online exam that is the student can take the exam any time anywhere, but the student might have to answer the questions in a limited time period. The professor may want to change the sequence of questions for every student. The problem that a student has is whenever a date for the exam is declared the student has to take it and there is no way he can take it at some other time. This project will create an interface for the examiner to create and store questions in a repository. It will also create an interface for the student to take examinations at his convenience and the questions and/or exams may be timed. Thereby creating an application which can be used by examiners and examinee’s simultaneously.
Examination System is very useful for Teachers/Professors. As in the teaching profession, you are responsible for writing question papers. In the conventional method, you write the question paper on paper, keep question papers separate from answers and all this information you have to keep in a locker to avoid unauthorized access. Using the Examination System you can create a question paper and everything will be written to a single exam file in encrypted format. You can set the General and Administrator password to avoid unauthorized access to your question paper. Every time you start the examination, the program shuffles all the questions and selects them randomly from the database, which reduces the chances of memorizing the questions.

A review on techniques and modelling methodologies used for checking electrom...nooriasukmaningtyas
The proper function of the integrated circuit (IC) in an inhibiting electromagnetic environment has always been a serious concern throughout the decades of revolution in the world of electronics, from disjunct devices to today’s integrated circuit technology, where billions of transistors are combined on a single chip. The automotive industry and smart vehicles in particular, are confronting design issues such as being prone to electromagnetic interference (EMI). Electronic control devices calculate incorrect outputs because of EMI and sensors give misleading values which can prove fatal in case of automotives. In this paper, the authors have non exhaustively tried to review research work concerned with the investigation of EMI in ICs and prediction of this EMI using various modelling methodologies and measurement setups.
