An integrated methodology for the performance and reliability evaluation of fault-tolerant systems
(Massachusetts Institute of Technology, 2007)
This thesis proposes a new methodology for the integrated performance and reliability evaluation of embedded fault-tolerant systems used in aircraft, space, tactical, and automotive applications. This methodology uses a ...
Visual attention models for far-field scene analysis
(Massachusetts Institute of Technology, 2007)
The amount of information available to an intelligent monitoring system is simply too vast to process in its entirety. One way to address this issue is by developing attentive mechanisms that recognize parts of the input ...
A model for the initiation and propagation of electrical streamers in transformer oil and transformer oil based nanofluids
(Massachusetts Institute of Technology, 2007)
The widespread use of dielectric liquids for high voltage insulation and power apparatus cooling is due to their greater electrical breakdown strength and thermal conductivity than gaseous insulators, while their ability ...
Virtual infrastructure for wireless ad hoc networks
(Massachusetts Institute of Technology, 2007)
One of the most significant challenges introduced by ad hoc networks is coping with the unpredictable deployment, uncertain reliability, and erratic communication exhibited by emerging wireless networks and devices. The ...
Low threshold vertical cavity surface emitting lasers integrated onto Si-CMOS ICs using novel hybrid assembly techniques
(Massachusetts Institute of Technology, 2007)
A new heterogeneous integration technique has been developed and demonstrated to integrate vertical cavity surface emitting lasers (VCSELs) on silicon CMOS integrated circuits for optical interconnect applications. Individual ...
Efficient and private distance approximation in the communication and streaming models
(Massachusetts Institute of Technology, 2007)
This thesis studies distance approximation in two closely related models - the streaming model and the two-party communication model. In the streaming model, a massive data stream is presented in an arbitrary order to a ...
A low-power cochlear implant system
(Massachusetts Institute of Technology, 2007)
Cochlear implants, or bionic ears, restore hearing to the profoundly deaf by bypassing missing inner-ear hair cells in the cochlea and electrically stimulating the auditory nerve. For miniaturized cochlear implants, including ...
A control mechanism for sales associates in high-end retail
(Massachusetts Institute of Technology, 2007)
The strength of the high-end retail industry has traditionally been in marketing and branding while management and operational efficiency lagged behind. In the face of changing client demographics and increased competition, ...
Optical and optoelectronic fiber devices
(Massachusetts Institute of Technology, 2007)
The ability to integrate materials with disparate electrical, thermal, and optical properties into a single fiber structure enabled the realization of fiber devices with diverse and complex functionalities. Amongst those, ...
Information theoretic sensor management
(Massachusetts Institute of Technology, 2007)
Sensor management may be defined as those stochastic control problems in which control values are selected to influence sensing parameters in order to maximize the utility of the resulting measurements for an underlying ...
