PDE-Based Modelling of Covid-19 Infections

Published by:

Dear ISIAM Members,

We are happy to release the first version of our “COVID-19: IISc Model”, which is  based on a high-dimensional population balance equation. Unlike the existing (Compartment or Network) pandemic models, the proposed model predicts the distribution of infected population across the region, the age of the infected people, the day since infection, and the severity of infection, over a period of time. Moreover, the newly developed model incorporates the immunity, pre-medical history, effective treatment, point-to-point movement of infected population (e.g., by air, train etc), interactivity (community spread), hygiene and the social distancing of the population.

A scenario analysis (beta version) of COVID-19 pandemic in India using the proposed model can be found at

We are pleased to announce that, by unanimous approval of the Executive Committee, Professor N.K. Gupta was chosen as the Interim President of ISIAM. We greatly appreciate his willingness to shoulder this responsibility at this critical time, following the unexpected passing away of Professor A.H. Siddiqi. Among other things, he will focus on establishing a more permanent leadership team of ISIAM as well as raising corpus funds for the Society. We are confident that you will provide your fullest support for Professor Gupta.

Memoriam: Professor Abul Hasan Siddiqi

Published by:

We regret to announce that Professor Abul Hasan Siddiqi, Professor Emeritus at Sharda University, Greater Noida, passed away suddenly on 20 January 2020, at the age of 77. He was an accomplished applied mathematician and played an important role in the development of the subject in India, mentored many young students in their research, and, besides his activities at Sharda University, was closely connected to his Alama Mater, Aligarh Muslim University (AMU). He was for many years the Secretary of the Indian Society of Industrial and Applied Mathematics (ISIAM) and was serving his term as its President at the time of his death. He will be missed by his familyhis many friends and colleagues.

Professor Siddiqi received his PhD from AMU in 1967. After two years of post-doctoral work in Germany, he joined AMU as a faculty member where he rose to the rank of Professor and served as the chairman of the Department of Mathematics, Provost of the Hall of Residence, Member-in-Charge of the AMU Press, Dean of the Faculty of Science, Chief Election Officer of the AMU and AMU students’ union. He held visiting appointments in different parts of the world including USA, Canada, Germany, Iran, Algeria, Saudi Arabia, Oman and Malaysia. From December 1973 to August 1975 Siddiqi was visiting professor at the University of Tabriz, Iran; from October 1980 to April 1983 at Constantine University, Algeria. From October 1998 to April 2007 he was employed as a Professor of Mathematics at the King Fahd University of Petroleum and Minerals, Saudi Arabia, and was also awarded DAAD fellowship at the Institute of Industrial and Business Mathematics, University of Kaiserslautern. He was a Senior Associate of the International Centre for Theoretical Physics (ICTP) in Trieste, Italy, and served the Gautam Buddha University from 2011 to 2013 towards whose development he contributed significantly.

Many applied mathematicians in India and around the world knew Siddiqi not only for his scientific work and the textbooks as well as monographs that he co-authored but also for his leadership in the applied mathematics community. One of his passions was ISIAM, which served as a platform for his international connections and his great desire to further the careers of many young students. The (roughly) biennial meetings that he organized under the Society’s aegis were events that attracted diverse groups of participants from abroad and India and held the community together with his attention to detail, his phenomenal energy and the large number of connections and friendships that he cultivated over time. He leaves behind a large vacuum.

The Conference was inaugurated by the King Excellency King Felipe VI of Spain on 15th July morning at Valencia Conference Centre. More than 4000 participants from all over the world attended the Conference.
152 Indian participants from different parts of India attended the Conference. 32 participants were fully supported by the National Board of Higher Mathematics, Atomic Energy Commission. Prof. A.H. Siddiqi, President ISIAM and  Prof. Pammy Manchanda, Secretary ISIAM organised a Minisymposium on “Current Developments in Wavelet- Fractal methods with Applications” in four parts. Speakers included Prof. Maria Skopina (St Petersburg University, Russia), Prof. Yuvi Farkov( Russain Presidential Academy of National Economy and Public Administration, Moscow, Russia),  Prof. T. Khan (Clemson University, USA), Prof. Akhtar Khan (Rochester Institute of Technology, USA), Prof. Nekka Fahima (Montreal University, Canada), Prof. Luis Manuel Sanchez Ruiz (Polytechnic University, Valencia, Spain), Prof. Aycil Cesmelioglu (Oakland University, Rochester, USA) Prof. Zafer Aslan (Istanbul Ayden University, Turkey), Prof Rashmi Bhardwaj(Guru Gobind Singh Indraprastha University, Delhi), Prof. A.H. Siddiqi and Prof. Pammy Manchanda (Organisers).
On 17th July 2019, ISIAM organised a get together of Indian participants at a nearby restaurant of the venue of the Conference. It was attended by Dr Shiv Kumar Singh Executive Head of NBHM besides Prof. Balachandran, Treasurer of ISIAM and local Organiser of the 15th Biennial Conference of ISIAM  to be held at Coimbatore during 5-7 Dec. 2019 and about 35 participants.
During this meeting, President Prof. A.H. Siddiqi highlighted the emerging trends in Industrial and Applied Mathematics. It was clear from the program that the Organisers want to focus on Artificial Intelligence and Big Data and Role of Mathematics in Medical Sciences. He also emphasized that Indian researchers should try to learn new and useful developments in applications of Mathematics and relevance of Mathematics to various aspects of Society requirements.
Dr Shiv Kumar Singh focused on Priorities of NBHM. Prof. Balachandran and other Organisers of the conference at Coimbatore extended warm Invitation for the ISIAM conference to be held in Coimbatore. Every part of India was represented in the meeting.
The Board meeting of the apex body of Industrial and applied Mathematics-(International Council of industrial and Applied mathematics) which organises these conferences namely ICIAM was held on 20th July 2019 at SH. Valencia Palace hotel meeting from 9 a.m. to 6 p.m. India was represented by Prof. A.H. Siddiqi (President ISIAM) and Prof. P. Manchanda (Secretary ISAIM).
