Model Extraction and Active Learning
Machine learning models are increasingly being offered as a service by big companies such as Google, Microsoft and Amazon. They use Machine Learning as a Service (MLaaS) to expose these machine learning models to the ... -
Investigation of Multi-Axis Beam Steering using Diffraction Grating
Optical beam-steering is becoming a key optical functionality in free space optical links used for communication and sensing. For example, in recent times, compact, wide-angle, fast, multi-axis beam steering is used ... -
On Linear Codes in Projective Spaces
The projective space $\mathbb{P}_q(n)$ of order $n$ over a finite field $\mathbb{F}_q$ is defined as the collection of all subspaces of the ambient space $\mathbb{F}_q^n$. The Grassmannian $\mathcal{G}_q(n, k)$ is the set ... -
Stability Preserving Bisection Algorithms in Reaction-Diffusion Complex Networks
Reaction-Diffusion complex networks are ubiquitous in many pragmatic models of network of interacting nodes with individual dynamics, such as social interactions, neuronal functions, transportation models, ecological ... -
Parallel Smoothers for Multigrid Method in Heterogeneous CPU-GPU Environment
Real-world applications require the solution of large a sparse system of algebraic equations that arise from the discretization of partial di erential equations with the help of supercomputers. Modern supercomputers are ... -
Load Modulated Arrays for Multi-antenna Wireless Communications
Conventional multi-antenna transmitters use a separate RF chain (consisting of DACs, mixers, filters) and a power amplifier (PA) for each antenna element, and use modulation alphabets such as QAM/PSK for transmission. The ... -
Assessment of Direct Radiative Effects of Aerosols using Assimilated Datasets over the Indian Region
Uncertainties in estimation of radiative effects of aerosols, pose the primary challenge for the accurate climate impact assessment of aerosols. Especially, over the Indian region which is characterized by significant ... -
Experimental and Numerical Studies to Strengthen the Adhesive Bonded Single Lap Joint
In this work, an attempt has been made to strengthen the adhesive bonding using various concepts like hybrid joints, dual and mixed adhesive bonded joints. One of the most commonly occurrence of defect in adhesive bonded ... -
Density Stratified Thermal Energy Storage System and Associated Fluid Dynamic Perturbations
The hunger of humankind for energy has reached unprecedented levels with the ever-rising industrialization and global population surge. We are witnessing a global economic evolution towards a clean, affordable, sustainable ... -
Multimodal Duetting and Pair Formation in a Paleotropical False Leaf Katydid, Onomarchus uninotatus
The spectacular diversity in the pair-formation strategies among animal groups has attracted the attention of many over the years. The roots of this diversity lie in the diversity of challenges that males and females face ... -
Foraging Decisions of the Lesser False Vampire Bat, Megaderma Spasma in a Heterogeneous Landscape
Predators make various foraging decisions at different spatial and temporal scales. Such decisions can be studied at two levels: patch decisions at the landscape level, and prey decisions at the foraging patch level. In ... -
Constrained Adaptive Control of Nonlinear Systems with Application to Hypersonic Vehicles
Constraints in input, output, and states are evident in most of the practical systems. Explicitly incorporating these constraints into the control design process leads to its superior performance in general. Therefore, ... -
A micro-robotic system with integrated force sensing capability for manipulation of magentic particles in three dimensions
Micro-robotic systems are used in various fields of science and technology for the manipulation of objects of size less than a millimeter. Magnetic tweezers can be considered as micro-robotic systems due to their ability ... -
Electrochemical Conversion of Methyl Ketones to Esters
The need for sustainable and efficient organic synthesis has inspired chemists to embrace classic technologies like electrochemistry and photochemistry. In addition to being an environmentally benign method to synthesize ... -
