A Framework for Privacy-Compliant Delivery Drones
We present Privaros, a framework to enforce privacy policies on drones. Privaros is designed for commercial delivery drones, such as the ones that will likely be used by Amazon Prime Air. Such drones visit a number of host ...
Locally Reconstructable Non-malleable Secret Sharing
Non-malleable secret sharing (NMSS) schemes, introduced by Goyal and Kumar (STOC 2018), ensure that a secret m can be distributed into shares m1,...,mn (for some n), such that any t (a parameter <= n) shares can be ...
Design and Development of Opto-ThermoAcoustic (OTA) Measurement System to Differentiate Cancer from Adjacent Normal Breast Biopsy Tissue
Breast cancer is the most common cancer accounting for almost 11.7% of all cancer incidences and 6.9% of cancer-related deaths globally in 2020, as per Globocan 2020 report. Diagnosis of breast cancer requires microscopic ...
Design and Analysis of Integrated Optic Waveguide Grating for Sensor and Communication Applications
Waveguide gratings are widely being used for multitude of applications owing to high sensitivity,
immunity to electromagnetic interference, multiplexing capabilities, light weight and compactness.
Waveguide gratings on ...
Design and Analysis of Full-duplex Systems for Next-generation Wireless Communication Systems
To cater to the ever-growing demand for higher data rates, cellular networks and
wireless local area networks (WLANs) need to adopt innovative technologies. Full-duplex
(FD) is one such technology that promises to double ...
Tailoring optical and electrical characteristics of layered materials through van der Waals heterojunctions
The feasibility of isolation of layered materials and arbitrary stacking of different materials provide plenty of opportunities to realize van der Waals heterostructures (vdWhs) with desired characteristics. In this thesis, ...
Face Recognition in Unconstrained Environment
The goal of computer vision is to provide the ability to machines to understand image data and infer
the useful information from it. The inferences highly depend on the quality of the image data. But in
many real-world ...
Battle of Bandits: Online Learning from Subsetwise Preferences and Other Structured Feedback
The elicitation and aggregation of preferences is often the key to making better decisions. Be it a perfume company wanting to relaunch their 5 most popular fragrances, a movie recommender system trying to rank the most ...
Support Recovery from Linear Measurements: Tradeoffs in the Measurement-Constrained Regime
In this thesis, we study problems under the theme of discovering joint sparsity structure in a set of high-dimensional data samples from linear measurements. Our primary focus is on the regime where the number of samples ...
Spectrotemporal Processing of Speech Signals Using the Riesz Transform
Speech signals possess a rich time-varying spectral content, which makes their analysis a challenging signal processing problem. Developing methods for accurate speech analysis has a direct impact on applications such as ...
