We first consider thin piezoelectric shallow shells with variable thickness and show that the eigenvalues of the three dimensional problem are order square of thickness the corresponding scaled eigensolutions converge to the eigensolutions of a two dimensional model.
Dynamics of micro particles in fluids and the change in rheological parameters due to particle dynamics occur across many industries including many processes relevant to space programs. We developed solutions for some of the problems and the study will be continued. A set of ordinary differential equations governing the migration of an arbitrary forced spheroid in quiescent/ simple-shear/ uniform/ oscillating/ oscillating-shear flows at low Reynolds number is formulated and discussed, assuming a sufficiently diluted suspension to neglect the particle-particle interactions.
To understand the dynamics of WSB trajectories and develop algorithms to obtain WSB trajectories from Earth to Moon and Mars. The role of periodic orbits (PO) and manifolds associated with them in ballistic lunar capture is studied. As a first step towards orbiter missions, planar fly-by trajectories to the Moon were studied in the framework of Restricted three-body problem (RTBP). We attempt the construction of a WSB trajectory toMoon in the restricted four-body problem (RFBP) and its dynamics. An algorithm is developed to obtain WSB trajectories to the moon in a full force model.
Various types of stability analysis of nonlinear dynamical systems in connection with continuous neural network systems are investigated. The LMI tools and the method of Lyapunov functionals are being employed for the analysis.
Controllability is one of the fundamental properties of control systems which guarantees the ability of the system to be steered from any initial state to a desired final state by using suitable control functions. Controllability analysis for stand-alone systems linear systems has been extensively carried out in the literature. However, for nonlinear systems as well as systems with various other effects like delay, impulses, noises, fuzziness etc in state or control are to be explored for investigation.
We are honored to announce that the Indian Institute of Space Science and Technology (IIST) has been conferred the distinguished 5G Use Cases Labs award as part of the Government of India's "100 5G Use Cases Labs Initiative." This initiative is designed to nurture expertise and encourage active engagement in 5G and future technologies among students, educators, researchers, and the emerging startup community.
This visionary 5G Use Cases Labs program, introduced in the 2023-24 national budget, will be supervised by the Department of Telecommunications (DoT), Government of India.
The Indian Institute of Space Science and Technology (IIST) and Kerala Spacepark (KSPACE) have entered into a strategic partnership through the signing of a Memorandum of Understanding (MoU) aimed at fostering academic-industry collaboration and promoting innovation and entrepreneurship in the space technology domain.
The MoU was officially signed on 22nd April 2025 at Thiruvananthapuram by Prof. Dipankar Banerjee, Director, IIST and Shri G Levin, Chief Executive Officer, KSPACE, in the presence of officials and faculty members from both institutions.
A robust and dynamic supply chain can be developed using advanced digital technologies, enabling real-time information sharing. This study provides a conceptual framework for effective supply chain digitalization by considering the key decision-making factors and interrelationships. The key decision-making factors affecting the digitalization process are identified from the literature and consultation with industry and academia experts. A conceptual framework is developed using the integrated systems model approach and DIKW (Data, Information, Knowledge, and Wisdom) hierarchy.
Digital twin and physical internet adoption based on advanced digital technologies is gaining significance in the recent times. Digital twin is one of the enabling technologies that link actual physical system with its virtual depiction using advanced digital technologies. In order to leverage its potential, firms have instigated to adopt digital twin and physical internet for real-world applications.
The concept of eco-efficiency is an important step in the move towards sustainable development. In the present day business, organizations have to take care of both the economic growth and environmental impact. Eco-efficiency determines the value of a product considering its environmental impact. In this research, the eco-efficiency requirements of an electronics industry are analyzed. The Customer requirements (CRs) and Design requirements (DRs) are identified for increasing the eco-efficiency in the industry.
