The finding of these studies have recently been published in the journals Mechanical Systems and Signal Processing and Neural Computing and Applications, say sources from IIT Mandi.

Bridges

Bridges play a vital role in India’s infrastructure, with nearly 13500 of them across the country. These structures undergo natural ageing due to environmental factors like temperature fluctuations, and water and air exposure, compounded by heavy road traffic, say sources from IIT Mandi.

Recent advances

Recent advances in instrumentation, data analysis, and artificial intelligence (AI) tools like Deep Learning (DL) hold great promise for structural health monitoring (SHM) of bridges and other structures, say sources from IIT Mandi.

These technologies make it easier to detect, measure, understand, and even predict the evolution of defects over time. This, in turn, enables more effective planning of renovation or repair work, ultimately reducing maintenance costs and extending the lifespan and availability of bridges, say sources from IIT Mandi.

Data Driven Methods

Elaborating on their work, Dr Subhamoy Sen, IIT Mandi, said, they have employed data-driven methods like Machine Learning, AI, and Bayesian statistical inference to estimate a bridge’s health and predict its remaining usable life.

This outcome has the potential to reduce risks to infrastructure under operational and adverse loading conditions, said Dr Subhamoy of IIT Mandi.

Dynamic traits

Temperature fluctuations can greatly affect a bridge’s dynamic traits, especially prestressed concrete, and cable-stayed bridges.

It is therefore important to consider these temperature effects in both real-time and AI-based SHM.

IIT Mandi’s algorithm was rigorously validated on a real bridge in a cold region with extreme annual and daily temperature swings.

Detection

To assess the algorithm’s damage detection capabilities, the researchers initially tested it on an undamaged real bridge.

Subsequently, they intentionally induced damage in the computer model to evaluate the algorithm’s accuracy in pinpointing the damage’s location.

This testing confirmed the algorithm’s efficacy in identifying structural damage.

Study

In another related study, the researchers used advanced filtering techniques to estimate the condition of different structural components without the need for direct measurement of their connections.

This technique enables the separate assessment of each component’s health, which can in turn help in evaluating overall structural integrity.

The method was validated using computer simulations of a beam exposed to various forces and demonstrated robust performance in handling challenges like background noise and damage severity.

About IIT Mandi

IIT Mandi has nine Academic Schools and five major Research Centers. The Schools are the School of Biosciences and Bioengineering (SBBE), School of Chemical Sciences (SCS), School of Mathematical and Statistical Sciences (SMSS), School of Physical Sciences (SPS), School of Mechanical and Materials Engineering (SMME) School of Civil and Environmental Engineering (SCENE), School of Computing and Electrical Engineering (SCEE), School of Humanities and Social Sciences (SHSS), and School of Management (SOM).

The Centers are Advanced Materials Research Centre (AMRC), Centre for Design and Fabrication of Electrical Devices (C4DFED), BioX Centre, Indian Knowledge System and Mental Health Applications Centre (IKSMHA Centre) and Centre for Artificial Intelligence and Robotics.

The Institute offers B.Tech. programs in seven different streams, one M.A. program, ten M.Tech. programs, nine Ph.D. programs, and one iPh.D. program.

The unique, project-oriented B.Tech. curriculum is centered around its 4-year long Design and Innovation stream. Since the inception of the Institute, IIT Mandi faculty have been involved in over 275 Research and Development (R&D) projects worth more than Rs. 120 crores.

It established the IIT Mandi iHub and HCI Foundation (iHub; a section-8 company) on its campus at Kamand with significant funding of INR 110 crores from the Department of Science and Technology (DST), Government of India.

The iHub is planned to fuel research and technology development, skill development, startup and innovation, and collaborations in the HCI and allied AI/ML areas in India.

This organization is the only second-generation IIT to be featured at rank 7 in the Atal Ranking of Institutions on Innovation Achievements of the Innovation Cell, Ministry of Education, Govt. of India.

The schedule to submit applications for JEE Advanced 2025 has been announced along with that of AAT 2025 registration,

Application process for AAT starts after result declaration of JEE Advanced. This year too, the trend is no different.

Who will conduct AAT 2025?

AAT 2025 will be conducted by IIT Kanpur and is expected to see a participation in impressive numbers. The same institution is conducting JEE Advanced 2025.

Details about the exam are available on the official website mentioned above. Students who pass AAT 2025 will be able to study BArch in IIT Roorkee, IIT Kharagpur and IIT (BHU) Varnasi.

Who can take up AAT 2025 registration?

Students who have passed JEE Advanced 2025 with required qualifying marks can take up AAT 2025 registration. Applying for JEE Advanced requires a pass in JEE Mains.

Candidates who have passed plus two with maths, physics and chemistry as subjects will be able to take up JEE Mains registration. The process to take up JEE Advanced AAT 2025 registration is online.

1. The URL has to be typed into the browser and the webpage has to be allowed to download.

2. Once the website is available, students should click the link for JEE Advanced AAT 2025 registration and enter JEE Advanced 2025 registration number, their date of birth, mobile number and email address.

3. Post providing the above details, applicants will be asked if they are interested in AAT. Students have to answer ‘Yes’ to take up JEE Advanced AAT 2025 registration.

4. Candidates have to provide the required information and choose the centers where they wish to write the exam and submit the form.

5. They will receive message indicating successful completion of JEE Advanced AAT 2025 registration.

The message has to be downloaded and a printout of it has to be taken and preserved for use in future. This could be of use during the admission process.

Website for JEE Advanced 2025/AAT 2025 Registration is Here
