Wicked Problems and Gnarly Results: Reflecting on Design and Evaluation Methods for Idiosyncratic Personal Information Management Tasks
(2008-02-10)
This paper is a case study of an artifact design and evaluation process; it is a reflection on how right thinking about design methods may at times result in sub-optimal results. Our goal has been to assess our decision ...
Finding Bugs In Dynamic Web Applications
(2008-02-06)
Web script crashes and malformed dynamically-generated web pages are common errors, and they seriously impact usability of web applications. Currenttools for web-page validation cannot handle the dynamically-generatedpages ...
Exploiting Transport-Level Characteristics of Spam
(2008-02-15)
In the arms race to secure electronic mail users and servers fromunsolicited messages (spam), the most successful solutions employtechniques that are difficult for spammers to circumvent. Thisresearch investigates the ...
Learning Grammatical Models for Object Recognition
(2008-02-25)
Many object recognition systems are limited by their inability to share common parts or structure among related object classes. This capability is desirable because it allows information about parts and relationships in ...
Making Medical Records More Resilient
(2008-02-17)
Hurricane Katrina showed that the current methods for handling medicalrecords are minimally resilient to large scale disasters. This research presents a preliminary model for measuring the resilience of medical records ...
ATAC: A Manycore Processor with On-Chip Optical Network
(2009-05-05)
Ever since industry has turned to parallelism instead of frequency scaling to improve processor performance, multicore processors have continued to scale to larger and larger numbers of cores. Some believe that multicores ...
Remote Store Programming: Mechanisms and Performance
(2009-05-05)
This paper presents remote store programming (RSP). This paradigm combines usability and efficiency through the exploitation of a simple hardware mechanism, the remote store, which can easily be added to existing ...
Fragment Grammars: Exploring Computation and Reuse in Language
(2009-03-31)
Language relies on a division of labor between stored units and structure building operations which combine the stored units into larger structures. This division of labor leads to a tradeoff: more structure-building means ...
Risk Allocation for Multi-agent Systems using Tatonnement
(2009-04-22)
This paper proposes a new market-based distributed planning algorithm for multi-agent systems under uncertainty, called MIRA (Market-based Iterative Risk Allocation). In large coordination problems, from power grid management ...
Oblivious Routing in On-Chip Bandwidth-Adaptive Networks
(2009-03-27)
Oblivious routing can be implemented on simple router hardware, but network performance suffers when routes become congested. Adaptive routing attempts to avoid hot spots by re-routing flows, but requires more complex ...
