A Declarative Approach to Hardening Services Against QoS Vulnerabilities
(IEEE, 2011)The Quality of Service (QoS) in a distributed service-oriented application can be negatively affected by a variety of factors. Network volatility, hostile exploits, poor service management, all can prevent a service-oriented ... -
A diffusion-viscous analysis and experimental verification of defect formation in sintered silver bond-line
(Cambridge University Press, 2014-04-01)The low-temperature joining technique (LTJT) by silver sintering is being implemented by major manufacturers of power electronic devices and modules for bonding power semiconductor chips. A common die-attach material used ... -
A Framework for Occupancy Tracking in a Building via Structural Dynamics Sensing of Footstep Vibrations
(Frontiers, 2017-11-06)Counting the number of occupants in building areas over time—occupancy tracking— provides valuable information for responding to emergencies, optimizing thermal conditions or managing personnel. This capability is distinct ... -
A human exposome framework for guiding risk management and holistic assessment of recycled water quality
(Royal Society of Chemistry, 2016-04-12)Challenges associated with water scarcity and increasing water demand are leading many cities around the globe to consider water reuse as a step towards water sustainability. Recycled water may be used in a spectrum of ... -
A Modest Proposal for Open Market Risk Assessment to Solve the Cyber-Security Problem
(Virginia Tech, 2016-04-29)We introduce a model for a market based economic system of cyber-risk valuation to correct fundamental problems of incentives within the information technology and information processing industries. We assess the makeup ... -
A Simulation Optimization Approach to Epidemic Forecasting
(PLOS, 2013-06-27)Reliable forecasts of influenza can aid in the control of both seasonal and pandemic outbreaks. We introduce a simulation optimization (SIMOP) approach for forecasting the influenza epidemic curve. This study represents ... -
A systematic review of studies on forecasting the dynamics of influenza outbreaks
(Wiley, 2013-12-23)Forecasting the dynamics of influenza outbreaks could be useful for decision-making regarding the allocation of public health resources. Reliable forecasts could also aid in the selection and implementation of interventions ... -
Aberrant Calcium Signaling in Astrocytes Inhibits Neuronal Excitability in a Human Down Syndrome Stem Cell Model
(Elsevier, 2018-07-10)Down syndrome (DS) is a genetic disorder that causes cognitive impairment. The staggering effects associated with an extra copy of human chromosome 21 (HSA21) complicates mechanistic understanding of DS pathophysiology. ... -
Ablation outcome of irreversible electroporation on potato monitored by impedance spectrum under multi-electrode system
(2018-09-20)Background Irreversible electroporation (IRE) therapy relies on pulsed electric fields to non-thermally ablate cancerous tissue. Methods for evaluating IRE ablation in situ are critical to assessing treatment ... -
The Abridgment and Relaxation Time for a Linear Multi-Scale Model Based on Multiple Site Phosphorylation
(PLOS, 2015-08-11)Random effect in cellular systems is an important topic in systems biology and often simulated with Gillespie’s stochastic simulation algorithm (SSA). Abridgment refers to model reduction that approximates a group of ... -
Abstraction Mechanisms in Support of Top-Down and Bottom-Up Task Specification
(Department of Computer Science, Virginia Polytechnic Institute & State University, 1988), TR-88-15Abstraction is a powerful mechanism for describing objects and relationships from multiple, yet consistent, perspectives. When properly applied to interface design, abstraction mechanisms can provide the interaction ... -
The Abstraction Refinement Model and the Modification-Cost Problem
(Department of Computer Science, Virginia Polytechnic Institute & State University, 1992), TR-92-29A problem common to systems and software engineering is that of estimating the cost of making changes to a system. For system modifications that include changes to the design history of the system this is the "modification-cost" ... -
The Academy: A Community of Information Retrieval Agents
(1994-09-06)We commonly picture text as a sequence of words; or alternatively as a sequence of paragraphs, each of which is composed of a sequence of sentences, each of which is itself a sequence of words. It is also worth noting that ... -
Accelerating Data-Serial Applications on Data-Parallel GPGPUs: A Systems Approach
(Department of Computer Science, Virginia Polytechnic Institute & State University, 2008), TR-08-24The general-purpose graphics processing unit (GPGPU) continues to make significant strides in high-end computing by delivering unprecedented performance at a commodity price. However, the many-core architecture of the GPGPU ... -
Accelerating Electrostatic Surface Potential Calculation with Multiscale Approximation on Graphics Processing Units
(Department of Computer Science, Virginia Polytechnic Institute & State University, 2009), TR-09-15Tools that compute and visualize biomolecular electrostatic surface potential have been used extensively for studying biomolecular function. However, determining the surface potential for large biomolecules on a typical ... -
Accelerating Workloads on FPGAs via OpenCL: A Case Study with OpenDwarfs
(Department of Computer Science, Virginia Polytechnic Institute & State University, 2016-05-13), TR-16-04For decades, the streaming architecture of FPGAs has delivered accelerated performance across many application domains, such as option pricing solvers in finance, computational fluid dynamics in oil and gas, and packet ... -
Acceleration Feedback-Based Active and Semi-Active Seismic Response Control of Rail-Counterweight Systems of Elevators
(Hindawi, 2005-01-01)Based on the observations in the past earthquake events, the traction elevators in buildings are known to be vulnerable to earthquake induced ground motions. Among several components of an elevator, the counterweight being ... -
