Applied Human Factors Research In Minimally Invasive Surgery, Caroline G. L. Cao Mar 2013

Applied Human Factors Research In Minimally Invasive Surgery, Caroline G. L. Cao

Physics Seminars

Health care is probably the last remaining unsafe critical system. A large proportion of reported medical errors occur in the hospital operating room (OR), a highly complex sociotechnical environment. From the technological point of view, there is a natural progression from traditional open surgery to minimally invasive surgery to robotic surgery. However, technology is being introduced into the OR faster than surgeons can learn to use them. Surgical errors have been attributed to the unfamiliar instrumentation, increased motoric, perceptual and cognitive demands on the surgeons, as well as the lack of adequate training. Effective technology design requires an understanding of …

Quantum Tricks In The Shadows Of Relativity And The Coulomb Force: Teaching Devices And Students How To Think Ultra-Fast, Ilias Perakis Mar 2013

Quantum Tricks In The Shadows Of Relativity And The Coulomb Force: Teaching Devices And Students How To Think Ultra-Fast, Ilias Perakis

Physics Seminars

The technological demand to bump the Gigahertz switching speed limit of today's magnetic memory and logic devices into the Terahertz regime underlies the entire field of spin-electronics and integrated multi-functional nano-devices. In this talk, I use theory and experiment to show how all-optical switching based on the quantum-mechanical manipulation of spins with a train of laser pulses could meet this challenge. The creation of magnetic correlations within femtoseconds, i.e. faster than one period of lattice oscillations, reveals a new temporal regime of magnetism. This field opened new directions for manipulating materials out-of-equilibrium using Terahertz, Mid-infrared, and X-ray pulses.

Predicting Parkinson's Disease Progression With Smartphone Data, Pramod Anantharam, Krishnaprasad Thirunarayan, Vahid Taslimi, Amit P. Sheth

Kno.e.sis Publications

Most of the existing approaches for detecting diseases/risk score form observations (sensor and textual) ignore the presence of any prior knowledge of the disease. In this work, we start top-down by enumerating the symptoms of Parkinson's Disease (PD) and map the symptoms to its possible manifestations in sensor observations (bottom-up). We show such manifestations and further use these manifestations as features to build classifiers to differentiate between the PD patients and the control group.

Enhancing Ir Sensor Coupling Using Surface Plasmon Resonances, John S. Cetnar Jan 2013

Enhancing Ir Sensor Coupling Using Surface Plasmon Resonances, John S. Cetnar

Physics Seminars

The mid-infrared (mid-IR) region of the electromagnetic spectrum is defined from λ ~ 8 – 14 μm. There are many important applications for mid-IR sensing including military, scientific, medical, and commercial. Unfortunately, the performance of current mid-IR detectors is limited by low optical absorption. Surface plasmons (SPs) can be used to enhance the coupling between mid-IR radiation and mid-IR detectors. There are many structures that can generate SPs in the mid-IR region. Two particular structures, the grating coupler and the Sierpinski carpet, seem particularly interesting. The grating coupler is of interest because of its good performance and simplicity of fabrication. …

From Solute Transport To Chemical Weathering, Allen Hunt, Thomas E. Skinner Jan 2013

From Solute Transport To Chemical Weathering, Allen Hunt, Thomas E. Skinner

Physics Seminars

A theory for conservative solute transport, based on concepts from percolation theory, is applied directly to reactive solute transport. Chemical reactions are assumed to have reached equilibrium at the scale of an individual pore, but at larger length scales, equilibration is limited by solute transport velocities, which are not the same as fluid velocities! The results of this theory already predicted observed dispersivity values for conservative solute transport over ten orders of magnitude of length scale as well as the variation of solute arrival time distributions with medium saturation. We now show that the solute velocity predicts the time-dependence of …

Logical Linked Data Compression, Amit Krishna Joshi, Pascal Hitzler, Guozhu Dong Jan 2013

Logical Linked Data Compression, Amit Krishna Joshi, Pascal Hitzler, Guozhu Dong

Computer Science and Engineering Faculty Publications

Linked data has experienced accelerated growth in recent years. With the continuing proliferation of structured data, demand for RDF compression is becoming increasingly important. In this study, we introduce a novel lossless compression technique for RDF datasets, called Rule Based Compression (RB Compression) that compresses datasets by generating a set of new logical rules from the dataset and removing triples that can be inferred from these rules. Unlike other compression techniques, our approach not only takes advantage of syntactic verbosity and data redundancy but also utilizes semantic associations present in the RDF graph. Depending on the nature of the dataset, …

A Resolution Procedure For Description Logics With Nominal Schemas, Cong Wang, Pascal Hitzler Jan 2013

A Resolution Procedure For Description Logics With Nominal Schemas, Cong Wang, Pascal Hitzler

Computer Science and Engineering Faculty Publications

We present a polynomial resolution-based decision procedure for the recently introduced description logic ELHOVn(⊓), which features nominal schemas as new language construct. Our algorithm is based on ordered resolution and positive superposition, together with a lifting lemma. In contrast to previous work on resolution for description logics, we have to overcome the fact that ELHOVn(⊓) does not allow for a normalization resulting in clauses of globally limited size.
