Research and Innovation Snippets

Dual active bridge isolated DC-DC converters are now widely used in medium and high-power applications such as DC distribution systems, electric vehicle chargers, etc. A design methodology has been developed that minimizes current stress and enables lossless...

A necessary and sufficient condition for uniquely registering a system of point clouds (whose positions are known in different coordinate systems) in a global coordinate system [1] has been obtained. This was done by relating the registration problem to the rigidity...

This work demonstrates that in event-triggered control, the timing of the events carries implicit information. In particular, we have found necessary and sufficient data rates, under bounded communication delays, for asymptotic stabilization of linear systems with...

Cross-modal retrieval with image-text, sketch-image, etc. are gaining increasing importance due to abundance of data from multiple modalities, and applications like e-commerce, security, etc. In [1], we develop a novel approach which utilizes few labeled and remaining...

The performance of speech systems is degraded in the presence of noise. The principle of modulation filtering attempts to remove the spectro-temporal modulations that are susceptible to noise. While traditional approaches use modulation filters that are hand-crafted,...

DC microgrids (MG) are becoming popular as they offer several advantages over an AC MG. The interactions among different power converters in a DC MG can give rise to system-level stability challenges. Such undesirable interactions could be avoided by modifying the...

Semi-supervised generative adversarial networks (GANs) consist of neural networks tasked with learning the underlying distributions of each class of a target dataset, usually images. We approach the GAN learning problem from a novel perspective, one that is motivated...

RaGaVeRa Indic Technologies, a startup conceptualised at IISc by Ramakrishnan A G and Shiva Kumar H R and incubated by the Society for Innovation and development (SID) has developed the best ever quality TTS for Kannada, using about 44.8 hours of training data...

Accelerated aging studies are performed to study the estimated and residual life of transmission composite insulators in service and to establish better condition monitoring techniques. Several experimental facilities pertaining to the study as per international...

This work is motivated by the requirement of a high-speed generator system for direct-coupled operation with thermal turbomachinery operating at speeds in the range of 40,000 rpm to 60,000 rpm. This is a power electronic converter mainly built for controlling a...

In addition to its many benign effects, lightning is one of Mother Nature’s serious threats to life and property. Extensive measurements in the field and well designed  rocket experiments have enriched our knowledge of lightning. However, there are many mysteries of...

Architectures have been proposed that learn end‐to‐end mapping functions to improve the spatial resolution of natural images. Two arechitectures are proposed. The first one  formulates a nonlinear combination of image interpolation techniques using a convolutional...

Magnetic resonance imaging (MRI) is one of the most important medical imaging modalities owing to its non-invasiveness. To effectively use it to study fast physiological processes, it has to be operated in sparse-sampling mode such that it measures only a small...

To reduce carbon emissions into the environment, some of the conventional Synchronous Generations (SGs) in power systems are being replaced by Photovoltaic (PV) generations. Absence of inherent rotational inertia, power electronic interface, and the control...
