4 Johnson, Christopher R.Optimizing Inverse Electrocardiographic Problem: Hybrid and High-Order Finite Element MethodOne type of inverse problems in electrocardiography (ECG) is to non-invasively reconstruct epicardial electric potentials from body-surface measurements. We study how to design the finite element discretization of such problem, so as to optimize the conditioning and stability of the resulting num...
5 Widanagamaachchi, Wathsala Nayomi; Pascucci, ValerioImage registrationImage Registration is the process of overlaying two or more images of the same scene, taken at different times, from different viewpoints and/or by different sensors.
6 Zhao, Lu; Regehr, JohnComparing program logics for reasoning about safety propertiesTo prove memory write and controls transfers do not interfere with other programs in embedded systems. Hoare Logic with Bale Predicate; Hoare Logic with Separation Conjunction.2010-10-06
7 Thulasinathan, Aravindan; Pascucci, Valerio; Tierny, JulienTopology Based Surface Meshing and MorphingMorphing is a seamless transition from one image to the other, used in animation and motion pictures. Mesh Parameterization used in this process is a fundamental tool used for domain remeshing. In case of 2-manifolds for example, most approaches require that the input mesh be cut into one or mor...2010-10-06
8 Li, Guodong; Gopalakrishnan, Ganesh; Kirby, Robert Michael IiPUG : A Symbolic Verifier of GPU ProgramsPUG is a automated verifier for GPU programs written in C/CUDA. PUG verifies GPU kernels for Data Races, Barrier mismatches, Totally wrong results, and Weak memory model related bugs. SMT-based correctness checking methods for these error are often more scalable, general and modular.2010-10-06
9 Awasthi, Manu; Nellans, David W.; Sudan, Kshitij; Balasubramonian, RajeevABP : predictor based management of DRAM row buffersDRAM accesses are costly, especially in multicore systems. Future CMPs will run a mixed load of workloads/threads. Destructive interference at memory controller, spatio-temporal locality lost! DRAM row-buffer hits are least expensive, row-conflicts are most. Randomized memory access patterns re...2010-10-06
10 Johnson, Robert R.Patterns of patternsPurpose of this Poster is to demonstrate that it takes the patterns of values in all the many dimensions to place each patient in the final patterns shown in each of the 5 charts. The final patterns determine the ability of each technology to identify or distinguish patients in each class. It is p...Gene patterns; Colon cancer; Trapeze Interactive poster2010-03-15
11 Kasera, Sneha K.; Patwari, NealMobility Assisted Secret Key GenerationSignature Based Key Generation. Wireless link signature; multiple paths caused by radio waves; their measurements are good signatures of links; link signatures measured almost symmetrically at two ends of wireless link, but cannot be measured from another location; use for secret key establishment;...
12 Joshi, Sarang; Venkatasubramanian, SureshMatching shapes using the current distanceCurrent Distance: It was introduced by Vaillant and Glaunès as a way of comparing shapes (point sets, curves, surfaces). This distance measure is defined by viewing a shape as a linear operator on a k-form field, and constructing a (dual) norm on the space of shapes. Shape Matching: Given two s...
13 Li, Peng; Regehr, JohnT-check: bug finding for sensor networksA safety property is true if something bad never happens. If any state in an execution violates the safety property, the entire execution violates that property. A liveness property holds if something good will eventually happen. An execution satisfies a liveness property if the execution will en...2010-02-26
14 Regehr, John; Pagariya, Rohit PannalaljiDirect equivalence testingTesting embedded software is difficult. • Further complicated by presence of memory and type safety errors in software. • Compiler contain various known bugs. Developers are skeptical to upgrade the compilers. • Is your embedded software affected by memory safety and compilation erro...

16 Tripathi, Abhishek; Bremer, Peer-Timo; Pascucci, ValerioUnderstanding global climate changeWhat is Climate Modeling? Use of quantitative methods to simulate the interactions of the atmosphere, oceans, land surface, and ice. Average Global Temperatures indicate a warming trend but that alone does not explain why it is happening.
17 Nguyen, Hoa Thanh; Nguyen, Thanh Hoang; Freire, JulianaDeepPeep: A Form Search EngineWe present DeepPeep (http://www.deeppeep.org), a new search engine specialized in Web forms. DeepPeep uses a scalable infrastructure for discovering, organizing and analyzing Web forms which serve as entry points to hidden-Web sites. DeepPeep provides an intuitive interface that allows users t...
18 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
19 Grosset, Andre Vincent Pascal; Pascucci, ValerioInfinite ZoomAny image (apart from a fractal) has a finite resolution. On zooming in, we eventually see pixels. The aim of this project is to allow users to infinitely zoom in on an image.2010-10-06

24 Pugsley, Seth H; Spjut, Josef Bo; Nellans, David W; Balasubramonian, RajeevSWEL: hardware cache coherence protocols to map shared data onto shared cachesIn chip multiprocessors, replication of cache lines is allowed to reduce the latency each core has to access a cache line. Because of this replication, it is possible for one copy of data to become out of date if another copy of that data is modified. How a MESI protocol accomplishes this: ? K...
25 Gilbert, Nathan Alan; Riloff, Ellen M.Exploring Knowledge-Rich Solutions to Noun Phrase Coreference ResolutionCoreference resolution is the task of identifying coreferent expressions in text. Accurate coreference resolution can improve other tasks such as machine translation, information retrievel and document summarization. Currently, the best approaches involve some form of supervised Machine Learni...
