Power-Aware Computing with Dynamic Knobs
(2010-05-14)
We present PowerDial, a system for dynamically adapting application behavior to execute successfully in the face of load and power fluctuations. PowerDial transforms static configuration parameters into dynamic knobs that ...
iJam: Jamming Oneself for Secure Wireless Communication
(2010-06-07)
Wireless is inherently less secure than wired networks because of its broadcast nature. Attacks that simply snoop on the wireless medium successfully defeat the security of even 802.11 networks using the most recent security ...
EM2: A Scalable Shared-Memory Multicore Architecture
(2010-06-12)
We introduce the Execution Migration Machine (EM2), a novel, scalable shared-memory architecture for large-scale multicores constrained by off-chip memory bandwidth. EM2 reduces cache miss rates, and consequently off-chip ...
SIFT Flow: Dense Correspondence across Scenes and its Applications
(2010-05-08)
While image alignment has been studied in different areas of computer vision for decades, aligning images depicting different scenes remains a challenging problem. Analogous to optical flow where an image is aligned to its ...
ChitChat: Making Video Chat Robust to Packet Loss
(2010-07-05)
Video chat is increasingly popular among Internet users. Often, however, chatting sessions suffer from packet loss, which causes video outage and poor quality. Existing solutions however are unsatisfying. Retransmissions ...
Broadcasting in Unreliable Radio Networks
(2010-06-08)
Practitioners agree that unreliable links, which fluctuate between working and not working, are an important characteristic of wireless networks. In contrast, most theoretical models of radio networks fix a static set of ...
A hierarchical model of peripheral vision
(2011-06-17)
We present a peripheral vision model inspired by the cortical architecture discovered by Hubel and Wiesel. As with existing cortical models, this model contains alternating layers of simple cells, which employ tuning ...
jMWE v1.0.0
(2011)
jMWE is a Java library for constructing and testing Multi-Word Expression detectors. The library has three main facilities: (1) a detector API, (2) a MWE index facility, and (3) a test harness. This is version 1.0.0 of the ...
Understanding the Performance of Broadband Networks through the Statistical Analysis of Speed Tests - Supplemental materials
(2011-05-10)
Supplemental materials for the master thesis "Understanding the Performance of Broadband Networks Through the Statistical Analysis of Speed Tests", by Rubén García, submitted in May 2011 for the S.M. in Technology and ...
A Software Approach to Unifying Multicore Caches
(2011-06-28)
Multicore chips will have large amounts of fast on-chip cache memory, along with relatively slow DRAM interfaces. The on-chip cache memory, however, will be fragmented and spread over the chip; this distributed arrangement ...
