We live in a world where mobile devices such as smartphones, smart watches and tablets are commonplace. With rapid strides in technology, we have come a long way from the first main frame computer ENIAC, which occupied 167 ... -
Probabilistic Inference in Modern Genetic Linkage Analysis
(2013-07-23)Exact inference can be computationally intractable. When it is infeasible or impractical, one often resorts to approximate methods. This thesis focuses on the algorithms for approximate inference and their applications in ... -
Programmable Self-assembly For Microsystem Integration
(2014-04-30)This dissertation studies and improves upon template-based self-assembly processes as a suite of techniques for microsystem integration. We first provide an updated definition for microscale self-assembly, and provide a ... -
Programmable ultrasound color flow system
(2000)Ultrasound color flow systems are widely used in medical imaging because these are safe, noninvasive, and relatively inexpensive and displays images in real time. However to meet the real time requirement, these systems ... -
Programming Molecules and Cells: Design Architectures for Chemical Reaction and Gene Regulatory Networks
(2014-04-30)The stages of cell differentiation are often illustrated as a sequence of events and chemical cues that move a cell from one state to another. Differentiated cells send and receive signals to compute functions on their ... -
Proton Conducting Devices and Materials
The flow of protons is vital in biology, driving natural processes like the production of adenosine triphosphate (ATP) (1). Micro-scale fluctuations in pH can provide insight into neural activity and regulate cellular ... -
A Prototype System and Circuits for the Development of an Implantable H-bridge Stimulator ASIC in a Bulk CMOS Process
The opportunity to introduce nanometer sized circuits and systems into the body to treat or cure mental disorders, physical injuries, and genetic disabilities has put us at the forefront of a burgeoning industry. Implantable ... -
