Abstract This paper presents a Downsian model of political competition in which parties have incomplete but richer information than voters on policy effects. Each party can observe a private signal of the policy effects, while voters cannot. In this setting, voters infer the policy effects from

sharing many of the same goals as previous distributed file systems, our design has been driven by observations of our application workloads and technological environment, both current and anticipated, that reflect a marked departure from some earlier file system assumptions. This has led us to reexamine

is designed to be architecture independent whenever possible, making Pintools source compatible across different architectures. However, a Pintool can access architecture-specific details when necessary. Instrumentation with Pin is mostly transparent as the application and Pintool observe the application’s

, but with poor spatial and temporal resolution. A helicopter-based platform can make measurements on scales relevant for towers, especially close to the Earth’s surface, and can extend these measurements to account for spatial variability. Thus, the Duke University Helicopter Observation Platform (HOP

and making emergency aid decisions. The National Applied Research Laboratories has implemented the project “development of near real-time, high-resolution, global earth observation 3D platform for applications to environmental monitoring and disaster mitigation. ” This developmental project integrates earth

Determining the precipitation distribution across Antarctica presents challenges not found in the mid-latitudes. A lack of

Remote sensing from satellite or airborne platforms of land or sea surfaces in the visible and near infrared is strongly affected by the presence of the atmosphere along the path from Sun to Target (surface) to Sensor. This paper presents 6S (Second Simulation of the Satellite Signal in the Solar

to the provided NAS version in its exploitation of opportunities for parallel execution. Unfortunately, we observed memory constraints which prevented running the full sized tests, making performance comparison difficult. Given the observed results, however, it seems likely that our performance would compare

Social networks are popular platforms for interaction, communication and collaboration between friends. Researchers have recently proposed an emerging class of applications that leverage relationships from social networks to improve security and performance in applications such as email, web
