High-k Dielectrics For Metal-Insulator-Metal Capacitors
(2016-11-23)Metal-insulator-metal (MIM) capacitors are used for analog, RF, and DRAM applications in ICs. The International Technology Roadmap for Semiconductors (ITRS) specifies continuing increase in capacitance density (> 7 fF/ ... -
High-Rate And Information-Lossless Space-Time Block Codes From Crossed-Product Algebras
(2007-10-23)It is well known that communication systems employing multiple transmit and multiple receive antennas provide high data rates along with increased reliability. It has been shown that coding across both spatial and temporal ... -
High-rate MSR Codes, Interior-point Regenerating Codes, and Codes with Hierarchical Locality
Given the breath-taking pace at which the amount of data being generated on a daily basis is growing, and the keen desire to extract information from this data, there is strong interest within the storage industry, at ... -
How are visual object representations organized and used to perform tasks ?
We rely heavily on vision for our daily activities, and around 40% of our brain is dedicated to vision. It is known that during a visual task, the visual information falling on the retina is processed in a hierarchy of ... -
Hybrid Electromagnetic Solvers for EMIEMC
With advances in technology and increased design complexity in the automotive industry, Electromagnetic Interference (EMI) and Electromagnetic Compatibility (EMC) issues are becoming increasingly important. An accurate ... -
A Hybrid Knowledge-Based System for Process Plant Fault Diagnosis
(Indian Institute of Science, 2005-03-11)Knowledge-Based Systems (KBSs) represent a relatively new programming approach and methodology that has evolved and is still evolving as an important sub-area of Artificial Intelligence (AI) research. The most prevalent ... -
Hypothesis Testing under Communication Constraints - Theory and an Application in IoT
Applications in the Internet of Things (IoT) often demand enabling low-compute devices to perform distributed inference and testing by communicating over a low bandwidth link. This gives rise to a plethora of new problems ... -
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) ... -
