Understanding packet delivery performance in dense wireless sensor networks
, 2003
"... Wireless sensor networks promise fine-grain monitoring in a wide variety of environments. Many of these environments (e.g., indoor environments or habitats) can be harsh for wireless communication. From a networking perspective, the most basic aspect of wireless communication is the packet delivery ..."

Our findings have interesting implications for the design and evaluation of routing and medium-access protocols for sensor networks. Categories and Subject Descriptors C.2.1 [Network Architecture
Order Flow and Exchange Rate Dynamics
, 1999
"... Macroeconomic models of nominal exchange rates perform poorly. In sample, R 2 statistics as high as 10 percent are rare. Out of sample, these models are typically out-forecast by a naïve random walk. This paper presents a model of a new kind. Instead of relying exclusively on macroeconomic determina ..."

Evolution in open source software: A case study
- In Proc. of the 2000 IEEE Intl. Conference on Software Maintenance, ICSM ’00
, 2000
"... Most studies of software evolution have been performed on systems developed within a single company using traditional management techniques. With the widespread availability of several large software systems that have been developed using an “open source ” development approach, we now have a chance ..."

to examine these systems in detail, and see if their evolutionary narratives are significantly different from commercially developed systems. This paper summarizes our preliminary investigations into the evolution of the best known open source system: the Linux operating system kernel. Because Linux is large
PRELIMINARY COMMUNICATION Open Access
"... A new malonamide fluoroionophore possessing two pyrene moieties was synthesized. This bispyrene exhibited the fluorescence of the pyrene monomer (lem = 395 nm) and intramolecular excimer (lem = 467 nm) emissions. The designed derivative showed the excellent ion sensing ability to Cu 2+.The“on-off-of ..."
Abstract

“on-off-off ” and “off-on-off” fluorescence responses were demonstrated by the addition of the variable Cu 2+ concentration. The utilization of the dual off/on responses could apply to the estimation of the rough Cu 2+ concentration. Findings In recent years, researches on development of ion sensing with fluorescence
A Measurement Study of Vehicular Internet Access Using

"... The impressive penetration of 802.11-based wireless networks in many metropolitan areas around the world offers, for the first time, the opportunity of a “grassroots ” wireless Internet service provided by users who “open up ” their 802.11 (Wi-Fi) access points in a controlled manner to mobile clien ..."

A Practical Dynamic Buffer Overflow Detector
- In Proceedings of the 11th Annual Network and Distributed System Security Symposium
, 2004
"... Despite previous efforts in auditing software manually and automatically, buffer overruns are still being discovered in programs in use. A dynamic bounds checker detects buffer overruns in erroneous software before it occurs and thereby prevents attacks from corrupting the integrity of the system. D ..."

of these deficiencies. CRED finds all buffer overrun attacks as it directly checks for the bounds of memory accesses. Unlike the original referent-object based bounds-checking technique, CRED does not break existing code because it uses a novel solution to support program manipulation of out-of-bounds addresses

"... From line to dots: an improved computerised rod and frame system for testing subjective visual vertical and horizontal Sharon Docherty * , Jeff Bagust Background: Perception of subjective visual vertical (SVV) and horizontal (SVH) has traditionally been measured by rotating a mechanical rod either w ..."

. Findings: Preliminary results showed a higher than expected percentage of individuals with SVH errors < 0.5°. This was attributed to additional visual cues provided by the changing appearance of the rod as it approached the horizontal. A solution to this problem was sought by replacing the rod by two
User-guided 3D active contour segmentation of anatomical structures: Significantly improved efficiency and reliability
- NeuroImage
, 2006
"... Active contour segmentation and its robust implementation using level set methods are well-established theoretical approaches that have been studied thoroughly in the image analysis literature. Despite the existence of these powerful segmentation methods, the needs of clinical research continue to b ..."

To bridge the gap between methodological advances and clinical routine, we developed an open source application called ITK-SNAP, which is intended to make level set segmentation easily accessible to a wide range of users, including those
