Prospective and retrospective retooling of magnetic resonance imaging
(Georgia Institute of Technology, 2017-04-28)
At its heart, signal processing can be broken down into two broad categories based on a single core principle: attaining a signal based objective (higher resolution, reduction in noise interference, signal based statistical ...
Direction-of-arrival Estimation of Wideband Sources Using Sensor Arrays
(Georgia Institute of Technology, 2004-07-12)
Sensor arrays are used in many applications where their ability to localize signal sources is essential. For many applications, it is necessary to estimate the direction-of-arrival (DOA) of target sources. Although there ...
Programmable Analog Techniques For Precision Analog Circuits, Low-Power Signal Processing and On-Chip Learning
(Georgia Institute of Technology, 2006-07-10)
In this work, programmable analog techniques using floating-gate transistors have been developed to design precision analog circuits, low-power signal processing primitives and adaptive systems that learn on-chip. Traditional ...
Towards automatic food intake monitoring using wearable sensor-based systems
(Georgia Institute of Technology, 2016-08-02)
Automatic food intake monitoring using wearable sensor-based systems is an alternative to manual self-report methods. Automatic methods aim to quantitatively track aspects related to eating, drinking and/or any form of ...
Exploiting spatial and temporal redundancies for vector quantization of speech and images
(Georgia Institute of Technology, 2015-11-17)
The objective of the proposed research is to compress data such as speech, audio, and images using a new re-ordering vector quantization approach that exploits the transition probability between consecutive code vectors ...
Low-temperature-grown InGaAs quantum wells for optical device applications
(Georgia Institute of Technology, 1999-05)
Adaptive radar detection in the presence of textured and discrete interference
(Georgia Institute of Technology, 2013-07-02)
Under a number of practical operating scenarios, traditional moving target indicator (MTI) systems inadequately suppress ground clutter in airborne radar systems. Due to the moving platform, the clutter gains a nonzero ...
Centralization and synchronization of millimeter-wave coordinated multi-point transmission in heterogeneous fiber-wireless access networks
(Georgia Institute of Technology, 2017-03-15)
The objective of the proposed research is to study methods that improve reception quality in millimeter-wave wireless communications. Millimeter-wave bands provide sufficient spectral resource for directional small-cell ...
Design and evaluation of a multimodal assistive technology using tongue commands, head movements, and speech recognition for people with tetraplegia
(Georgia Institute of Technology, 2019-04-01)
People with high level (C1-C4) spinal cord injury (SCI) cannot use their limbs to do the daily life activities by themselves without assistance. Current assistive technologies (ATs) use remaining capabilities (tongue, ...
Reduced Energy Consumption and Improved Accuracy for Distributed Speech Recognition in Wireless Environments
(Georgia Institute of Technology, 2004-10-04)
The central theme of this dissertation is the study of a multimedia client for pervasive wireless multimedia applications. Speech recognition is considered as one such application, where the computational demands have ...
