302 Regehr, JohnEliminating stack overflow by abstract interpretationAn important correctness criterion for software running on embedded microcontrollers is stack safety: a guarantee that the call stack does not overflow. Our first contribution is a method for statically guaranteeing stack safety of interrupt-driven embedded software using an approach based on contex...2005-01-01
303 Regehr, JohnEliminating the call stack to save RAMMost programming languages support a call stack in the programming model and also in the runtime system.We show that for applications targeting low-power embedded microcontrollers (MCUs), RAM usage can be significantly decreased by partially or completely eliminating the runtime callstack. We presen...2009-01-01
304 Kirby, Robert Michael IIElVis: A system for the accurate and interactive visualization of high-order finite element solutionsThis paper presents the Element Visualizer (ElVis), a new, open-source scientific visualization system for use with high order finite element solutions to PDEs in three dimensions.

306 Riloff, Ellen M.Empirical approach to conceptual case frame acquisitionConceptual natural language processing systems usually rely on case frame instantiation to recognize events and role objects in text. But generating a good set of case frames for a domain is time-consuming, tedious, and prone to errors of omission. We have developed a corpus-based algorithm for a...Conceptual case frame acquisition; Case frame instantiation; Corpus-based algorithm1998
307 Riloff, Ellen M.Empirical study of automated dictionary construction for information extraction in three domainsA primary goal of natural language processing researchers is to develop a knowledge-based natural language processing (NLP) system that is portable across domains. However, most knowledge-based NLP systems rely on a domain-specific dictionary of concepts, which represents a substantial knowledge-en...Information extraction; AutoSlog; Across domains1996
308 Freire, Juliana; Silva, Claudio T.Enabling advanced visualization tools in a web-based simulation monitoring systemSimulations that require massive amounts of computing power and generate tens of terabytes of data are now part of the daily lives of scientists. Analyzing and visualizing the results of these simulations as they are computed can lead not only to early insights but also to useful knowledge that ca...Isosurfaces; Contour tree; Turbulent combustion; eSimMon2009-12
309 Freire, Juliana; Silva, Claudio T.End-to-end eScience: integrating workflow, query, visualization, and provenance at an ocean observatoryData analysis tasks at an Ocean Observatory require integrative and and domain-specialized use of database, workflow, visualization systems. We describe a platform to support these tasks developed as part of the cyberinfrastructure at the NSF Science and Technology Center for Coastal Margin Obser...Coastal margins; Ocean observatories; Workflow systems; VisTrails2008-12
310 Kasera, Sneha K.Energy efficient radio tomographic imagingIn this paper, our goal is to develop approaches to reduce the energy consumption in Radio Tomographic Imaging (RTI)-based methods for device free localization without giving up localization accuracy. Our key idea is to only measure those links that are near the current location of the moving object...2014-01-01
311 Balasubramonian, RajeevEnergy-efficient processor design using multiple clock domains with dynamic voltage and frequency scalingAs clock frequency increases and feature size decreases, clock distribution and wire delays present a growing challenge to the designers of singly-clocked, globally synchronous systems. We describe an alternative approach, which we call a Multiple Clock Domain (MCD) processor in which the chip is d...Multiple clock domains; Synchronization; Microarchitecture2002
312 Kasera, Sneha K.Enhancing covert communications with multiple colluding receiversTraditional (single receiver) system setup: ? Choose exploit field (e.g. last byte of TCP Timestamp) ? Alice: probabilistically inject parts of coded message into field ? Bob: extract symbols from field, decode to correct errors ?Warden: assume full knowledge of system and keys Can we create un...2010-10-06
313 Carter, JohnEnsuring prolonged participation and deterring cheating behaviors in a collectiveWe are building a system that harnesses the idle resources (cpu, storage, and bandwidth) of nodes (e.g., home desktops) distributed across the Internet to build useful distributed services like content distribution or remote backup. Users are compensated in return for contributing their nodes? id...Collective systems; Cheating; Idle resources; Nodes2008
314 Cohen, ElaineError bounded approximate reparametrization of NURBS curvesThis paper reports research on solutions to the following reparametrization problem: approximate c(r(t)) by a NURBS where c is a NURBS curve and r may, or may not, be a NURBS function. There are many practical applications of this problem including establishing and exploring correspondence in geomet...Reparametrization; NURBS curve2000
315 Cohen, ElaineError bounded variable distance offset operator for free from curves and surfacesMost offset approximation algorithms for freeform curves and surfaces may be classified into two main groups. The first approximates the curve using simple primitives such as piecewise arcs and lines and then calculates the (exact) offset operator to this approximation. The second offsets the contro...Error bounded; Freeform curves1991
316 Brunvand, Erik L.Estimating performance of an ray- tracing ASIC designRecursive ray tracing is a powerful rendering technique used to compute realistic images by simulating the global light transport in a scene. Algorithmic improvements and FPGA-based hardware implementations of ray tracing have demonstrated realtime performance but hardware that achieves performance ...2006
317 Done, William JohnEstimation of the parameters of an autoregressive process in the presence of additive white noiseApplications of linear prediction (LP) algorithms have been successful in modeling various physical processes. In the area of speech analysis this has resulted in the development of LP vocoders, devices used in digital speech communication systems. The LP algorithms used in speech and other areas ar...Autoregressive process; Linear prediction algorithms; All-pole model1979
318 Lindstrom, Gary E.ETYMA: a framework for modular systemsModularity, i.e. support for the flexible construction, adaptation, and combination of units of software, is an important goal in many systems. In most cases, however, systems achieve only a few aspects of modularity. The problem can be traced to the inflexibility, or the limited view of modularity ...ETYMA; Modularity; Modular systems1994
319 Thompson, William B.Evaluating the accuracy of size perception in real and virtual environmentsAccurate perception of the size of 3D objects depicted on 2D desktop displays is important for many applications. Whether users perceive objects depicted on a display to be the same size as comparable real world objects is not well understood. We propose using affordances judgments as a way of measu...2012-01-01
320 Carter, John B.Evaluating the potential of programmable multiprocessor cache controllersThe next generation of scalable parallel systems (e.g., machines by KSR, Convex, and others) will have shared memory supported in hardware, unlike most current generation machines (e.g., offerings by Intel, nCube, and Thinking Machines).

322 Henderson, Thomas C.Evolutionary teleomorphologyThe physical layout of organs and neural structures in biological systems is important to their functioning, and is the result of evolutionary selection forces. We believe this is true even at the individual neuron level, and should be accounted for in any bio-based approach. In particular, when tr...Evolutionary teleomorphology; Bio-based approach; Physical layout problem; PLP; Neurons; Nodes1995
323 Regehr, JohnEvolving real-time systems using hierarchical scheduling and concurrency analysisWe have developed a new way to look at real-time and embedded software: as a collection of execution environments created by a hierarchy of schedulers. Common schedulers include those that run interrupts, bottom-half handlers, threads, and events. We have created algorithms for deriving response tim...2003-01-01

325 Gopalakrishnan, GaneshExplicit-enumeration based verification made memory-efficientWe investigate techniques for reducing the memory requirements of a model checking tool employing explicit enumeration. Two techniques are studied in depth: (1) exploiting symmetries in the model, and (2) exploiting sequential regions in the model. The first technique resulted in a significant reduc...Verification; Model checking tool; Memory-efficient1995
