Imitation Learning Techniques for Robot Manipulation
Robots that can operate in unstructured environments and collaborate with humans play a major role in raising productivity and living standards as societies age. Unlike the robots currently used in industrial settings for ... -
Improved GMM-Based Classification Of Music Instrument Sounds
(2009-03-19)This thesis concerns with the recognition of music instruments from isolated notes. Music instrument recognition is a relatively nascent problem fast gaining importance not only because of the academic value the problem ... -
Index Coding, Error Correcting Index Codes And Matroids
In the problem of index coding, there is a central source sending messages to a set of receivers which demand messages over a noiseless broadcast channel. Each receiver knows a subset of messages which is referred to as ... -
Influence Dynamics on Social Networks
(2018-02-15)With online social networks such as Facebook and Twitter becoming globally popular, there is renewed interest in understanding the structural and dynamical properties of social networks. In this thesis we study several ... -
Information Rates over Point-to-Point and Multi-user Wireless Channels with Energy and Delay Constraints
In this thesis, we consider communication systems having energy, delay and reliability constraints. We characterize optimal communication rates achievable over these systems. First we consider point-to-point communication ... -
Information-rich Sampling of Time-varying Signals
Confrontation with signal non-stationarity is a rule rather than an exception in the analysis of natural signals, such as speech, animal vocalization, music, bio-medical, atmospheric, ans seismic signals. Interestingly, ... -
Insights into Network Coding Using Tools From Linear Algebra and Matroid Theory
Traditionally, the transmission of information through a network was carried out using store-and-forward techniques. This entails managing information bits in a network analogous to commodity flow, without mixing or combining ... -
Integrated Interfaces for Sensing Applications
(2017-12-13)Sensor interfaces are needed to communicate the measured real-world analog values to the base¬band digital processor. They are dominated by the presence of high accuracy, high resolution analog to digital converters (ADC) ... -
Integrated optic devices on thin film lithium niobate for few-mode optical communications
Mode division multiplexing is a remarkable strategy to meet the explosively increasing bandwidth requirements in optical communication systems and interconnects. This scheme harnesses the orthogonality of modes to scale ... -
Integrated Optic Microring Resonator based Sub-μN force and Force and Acceleration Sensors
Microring resonators have rapidly emerged in the past few years as a new sensing platform for miniaturization of modern integrated optical devices. Ring resonator are having advantages of compactness, stability with ... -
Integrated Optical Double Ring Resonators with MEMS for Pressure and Acceleration Sensing
Silicon Photonics has become a signi ficant area of research in last three decades because of its high speed operation, low power consumption and the most important feature, resistant to electro-magnetic interferences. ... -
Interference Cancelling Detectors In OFDMA/MIMO/Cooperative Communications
(2009-09-02)In this thesis, we focus on interference cancelling (IC) detectors for advanced communication systems. The contents of this thesis is divided into the following four parts: 1. Multiuser interference (MUI) cancellation in ... -
Interference Management For Vector Gaussian Multiple Access Channels
(2010-06-03)In this thesis, we consider a vector Gaussian multiple access channel (MAC) with users demanding reliable communication at specific (Shannon-theoretic) rates. The objective is to assign vectors and powers to these users ... -
Interference Modeling in Wireless Networks
(2017-10-26)Cognitive radio (CR) networks and heterogeneous cellular networks are promising approaches to satisfy the demand for higher data rates and better connectivity. A CR network increases the utilization of the radio spectrum ... -
Inverse Problems in 3D Full-wave Electromagnetics
An inverse problem in Electromagnetics (EM) refers to the process of reconstructing the physical system by processing the measured data of its electromagnetic properties. Inverse problems are typically ill-posed, and this ... -
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 ... -
