The past two decades in the United States have ushered in an era of increasing ubiquity of digitized healthcare as the speed and sophistication of technology follows an ever-growing trend. Electronic health records (EHRs) are ...

Reliability is an important requirement in network communication. Many distributed applications rely on exchanging information reliably in the presence of host crashes and network failures. In this thesis, our concern is ...

Failures in computing systems are unavoidable. Therefore, it is important to detect and diagnose failures early to improve the reliability of systems. In this dissertation, new approaches on root-cause diagnosis for two ...

Compaction plays a crucial role in NoSQL systems to ensure a high overall read throughput. In this work, we formally define compaction as an optimization problem that attempts to minimize disk I/O.We prove this problem to ...

3D neuro-anatomical images and other volumetric data sets are important in many scientific and biomedical fields. Since such sets may be extremely large, a scalable compression method is critical to store, process and ...

The ultimate goal of computer vision is to understand images. We describe methods to understand images at two levels. One is at the level of description of images which we produce using sentences. These sentences talk ...

Polarizable force fields are considered to be the single most significant development in the next-generation force fields used in biomolecular simulations. The self-consistent computation of induced atomic dipoles in a ...

One of the fundamental problems of artificial intelligence is learning how to behave optimally. With applications ranging from self-driving cars to medical devices, this task is vital to modern society. There are two ...

Reconfigurable chips can be used to enhance the yield of chip production. These chips contain redundant elements that can be used to replace the defective elements. The fault covering problem is to assign the redundant ...

A general class of fault-tolerant multistage interconnection networks is introduced, wherein fault tolerance is achieved by providing non-unique paths between each input and each output. The topology of the multiple paths ...
