Long Term Measurement of Bandgap Voltage and System Level Integral Non-Linearity Drift
(Massachusetts Institute of Technology, 2022-09)
All modern precision measurement systems require voltage references that are stable across all variables, namely temperature and time. Most of these references are made through bandgap voltage circuits. While it is impossible ...
Delivering Locally Sourced Nutritious Food to Indian Households
(Massachusetts Institute of Technology, 2021-06)
WHO reports that in the South Asian region, the number of undernourished has hardly decreased in the last decade. This situation calls for a concerted effort to combat malnutrition the world over. The effort must be grounded ...
Learning Refinement Cost Estimators for Bilevel Planning
(Massachusetts Institute of Technology, 2023-06)
Bilevel planning is an effective approach for solving complex task and motion planning (TAMP) problems with continuous state and action spaces, that involves first searching for a high-level abstract plan and then refining ...
Optimal Reinforcement Learning with Black Holes
(Massachusetts Institute of Technology, 2022-02)
We introduce the Black Hole Reinforcement Learning problem, a previously unexplored variant of reinforcement learning in which we lose all turn information and all reward from trajectories that visit a particular subset ...
Scene Text Localization and Recognition for Images of Serial Numbers and Odometer Readings
(Massachusetts Institute of Technology, 2022-02)
This thesis investigates deep learning models and methods to create a full scene text extraction system. The system is composed of two main parts, a localization network and a recognition network, with the recognition ...
Agent-Based Approach to Simulating Mobility as a Service
(Massachusetts Institute of Technology, 2022-02)
As a result of the changing transportation landscape, Mobility-as-a-Service (MaaS) was developed to be a streamlined operator of emerging on-demand transportation services and traditional modes of transport. However, much ...
Implementation of cybersecure observers and control in microgrids; energy dynamics based approach
(Massachusetts Institute of Technology, 2022-02)
Today's microgrids are modeled as dynamical systems with multiple physical components that interact. Microgrids are essentially small blocks that make up the larger energy grid and they are independent, meaning they can ...
A Basic Isolated Half-Bridge Silicon Carbide Gate Driver for Electric and Hybrid Electric Vehicles
(Massachusetts Institute of Technology, 2022-02)
A Basic, Isolated, Half-Bridge Silicon Carbide Gate Driver was designed and validated using Cadence and SPICE. The architectures of similar gate drivers were studied and simplified to reduce the total area of the gate ...
Reverse Engineering the Intel Cascade Lake Mesh Interconnect
(Massachusetts Institute of Technology, 2021-06)
The rising core counts of multicore processors have driven the move to more scalable on-chip networks to allow for efficient communication between the cores, memory subsystem, and other processor peripherals. Intel’s latest ...
Development and Evaluation of Generative Adversarial Networks for Predicting Central Hemodynamics
(Massachusetts Institute of Technology, 2022-05)
A comprehensive assessment of cardiovascular function requires measurement of central hemodynamic values (e.g pressures in the chambers of the heart and the pulmonary vessels). The current gold standard for obtaining these ...
