Design and demonstration of integrated micro-electro-mechanical relay circuits for VLSI applications
(Massachusetts Institute of Technology, 2013)
Complementary-Metal-Oxide-Semiconductor (CMOS) feature size scaling has resulted in significant improvements in the performance and energy efficiency of integrated circuits in the past 4 decades. However, in the last decade ...
Gate-all-around silicon nanowire MOSFETs : top-down fabrication and transport enhancement techniques
(Massachusetts Institute of Technology, 2010)
Scaling MOSFETs beyond 15 nm gate lengths is extremely challenging using a planar device architecture due to the stringent criteria required for the transistor switching. The top-down fabricated, gate-all-around architecture ...
Solar thermoelectrics for small scale power generation
(Massachusetts Institute of Technology, 2012)
In the past two decades, there has been a surge in the research of new thermoelectric (TE) materials, driven party by the need for clean and sustainable power generation technology. Utilizing the Seebeck effect, the ...
Understanding freehand diagrams : combining appearance and context for multi-domain sketch recognition
(Massachusetts Institute of Technology, 2012)
As our interaction with computing shifts away from the traditional desktop model (e.g., towards smartphones, tablets, touch-enabled displays), the technology that drives this interaction needs to evolve as well. Wouldn't ...
Communication and energy delivery architectures for personal medical devices
(Massachusetts Institute of Technology, 2012)
Advances in sensor technologies and integrated electronics are revolutionizing how humans access and receive healthcare. However, many envisioned wearable or implantable systems are not deployable in practice due to high ...

A 2D + 3D rich data approach to scene understanding
(Massachusetts Institute of Technology, 2013)
On your one-minute walk from the coffee machine to your desk each morning, you pass by dozens of scenes - a kitchen, an elevator, your office - and you effortlessly recognize them and perceive their 3D structure. But this ...
Design and analysis of digital watermarking, information embedding, and data hiding systems
(Massachusetts Institute of Technology, 2000)
Digital watermarking, information embedding, and data hiding systems embed information, sometimes called a digital watermark, inside a host signal, which is typically an image, audio signal, or video signal. The host signal ...
Conservation in signal processing systems
(Massachusetts Institute of Technology, 2012)
Conservation principles have played a key role in the development and analysis of many existing engineering systems and algorithms. In electrical network theory for example, many of the useful theorems regarding the ...
