Surface Modification at Nanoscale; Nanoparticle-Nanowire Transition
(NASA, 2018-04-15)Binary, ternary and quaternary oxides and selenides have been developed and used in multiple applications including high power lasers, detectors, dielectric energy storage and variety of optical devices. These materials ... -
Design and characteristics of hydroxyapatites: effect of radiation
(Society of Photo-Optical Instrumentation Engineers (SPIE), 2018-05-14)We have prepared silicate based hard materials and have processed it with organic flux. Because of the bioactivities of hydroxyapatites with tissues, this class of materials have attracted interest for bone applications. ... -
Multidisciplinary Education on Big Data + HPC + Atmospheric Sciences
(National Science Foundation, 2017-11-01)We present a new initiative to create a training program or graduate-level course (cybertraining.umbc.edu) in big data applied to atmospheric sciences as application area and using high-performance computing as indispensable ... -
Speedup Potential for Reconstruction Techniques for Prompt Gamma Imaging During Proton Radiotherapy
Proton beam radiation treatment was first proposed by Robert Wilson in 1946. The advantage of proton beam radiation is that the lethal dose of radiation is delivered by a sharp increase toward the end of the beam range. ... -
Developing the Coupling of the Mechanical to the Electrical and Calcium Systems in a Heart Cell
(2017)As the leading cause of death in the United States, heart disease has become a principal concern in modern society. Cardiac arrhythmias can be caused by a dysregulation of calcium dynamics in cardiomyocytes. Calcium ... -
An Investigation of Small Worldness in Pancreatic Islets
(2017)Diabetes occurs when the body’s blood sugar levels are in a state of sustained elevation. The pancreatic beta cells, organized in the islets of Langerhans, secrete a hormone called insulin that is responsible for maintaining ... -
A Parallel Performance Study of the High-order Compact Direct Flux Reconstruction Method for Conservation Laws on Maya Cluster
(2017)The compact direct flux reconstruction method (CDFR) for conservation laws utilizes techniques from compact finite difference methods to directly approximate spatial derivatives of fluxes within standard elements. The CDFR ... -
A Linearized Viscous, Compressible Flow-Plate Interaction with Non-dissipative Coupling
We address semigroup well-posedness for a linear, compressible viscous fluid interacting at its boundary with an elastic plate. We derive the model by linearizing the compressible Navier-Stokes equations about an arbitrary ... -
Numerical Methods for Parallel Simulation of Diffusive Pollutant Transport from a Point Source
In an interdisciplinary project combining Atmospheric Physics, High Performance Computing, and Big Data, we explore a numerical method for solving a physical system modeled by a partial differential equation. The application ... -
Zero-Day Attack Identification in Streaming Data Using Semantics and Spark
(IEEE, 2017-09-11)Intrusion Detection Systems (IDS) have been in existence for many years now, but they fall short in efficiently detecting zero-day attacks. This paper presents an organic combination of Semantic Link Networks (SLN) and ... -
A Deterministic Self-Organizing Map Approach and its Application on Satellite Data based Cloud Type Classification
A self-organizing map (SOM) is a type of competitive artificial neural network, which projects the high-dimensional input space of the training samples into a low-dimensional space with the topology relations preserved. ... -
Performance of Eyes-Free Mobile Authentication Work in Progress
(The Internet Society, 2018-02-18)Mobile device users avoiding observational attacks and coping with situational impairments may employ techniques for eyes-free mobile unlock authentication, where a user enters his/her passcode without looking at the device. ... -
Rapid recombinant protein expression in cell-free extracts from human blood
(Nature, 2018-06-22)Several groups have recently reported on the utility of cell-free expression systems to make therapeutic proteins, most of them employing CHO or E. coli cell-free extracts. Here, we propose an alternative that uses human ... -
Efficiently Modeling the Noise Performance of Short-Pulse Lasers with a Computational Implementation of Dynamical Methods
Lowering the noise level of short pulse lasers has been a long-standing effort for decades. Modeling the noise performance plays a crucial role in isolating the noise sources and reducing them. Modeling to date has either ... -
Quantum to classical transition in an information ratchet
Recent years have seen a flurry of research activity in the study of minimal and autonomous information ratchets. However, the existing classical and quantum models are somewhat hard to compare, and, hence, quantifying ... -
An Introduction to the Syntax and Content of Cyc
(Association for the Advancement of Artificial Intelligence (AAAI), 2006-03)From the beginning, a primary goal of the Cyc project has been to build a large knowledge base containing a store of formalized background knowledge suitable for supporting reasoning in a variety of domains. In this paper, ... -
Automated Population of Cyc: Extracting Information about Namedentities from the Web
(Association for the Advancement of Artificial Intelligence (AAAI), 2006-02-13)Populating the Cyc Knowledge Base (KB) has been a manual process until very recently. However, there is currently enough knowledge in Cyc for it to be feasible to attempt to acquire additional knowledge autonomously. This ... -
Guiding Inference with Policy Search Reinforcement Learning
(Association for the Advancement of Artificial Intelligence (AAAI), 2007-05)Symbolic reasoning is a well understood and effective approach to handling reasoning over formally represented knowledge; however, simple symbolic inference systems necessarily slow as complexity and ground facts grow. As ... -
Autonomous Classification of Knowledge into an Ontology
(Association for the Advancement of Artificial Intelligence (AAAI), 2007-02-11)Ontologies are an increasingly important tool in knowledge representation, as they allow large amounts of data to be related in a logical fashion. Current research is concentrated on automatically constructing ontologies, ... -
A Spotlight on Security and Privacy Risks with Future Household Robots: Attacks and Lessons
(ACM, 2009-09-30)Future homes will be populated with large numbers of robots with diverse functionalities, ranging from chore robots to elder care robots to entertainment robots. While household robots will offer numerous benefits, they ...
