Protocol Boosters are functional elements, inserted and deleted from network protocol stacks on an as-needed basis. The Protocol Booster design methodology attempts to improve end-to-end networking performance by adapting protocols to network dynamics. We describe a new dynamically reconngurable FPGA based architecture , called the Programmable Protocol Processing Pipeline (P4), which provides ...

Hepatitis A and B are serious vaccine-preventable diseases with a predominantly overlapping epidemiological distribution. Travelers, a term encompassing a range of individuals, are at risk of contracting these diseases if they are unvaccinated. Although the benefits of the primary vaccination course of hepatitis A and B vaccines are clear, the administration of hepatitis A and B boosters varies...

The effect of various household sanitizers including water, water acidified with white vinegar (1.5%), vinegar and lemon juice were evaluated for their effectiveness in reducing counts of Salmonella typhimurium on rocket and lettuce leaves. Treating rocket and lettuce samples with water containing 1.5% vinegar for 30 min or washing with water (at 28C) for 5 min showed negligible reduction in pa...

Ovipositional preference and larval survival of the diamondback moth, Plutella xylostella (L.), were compared among cabbage, Brassica oleracea L. variety capitata; glossy collards, Brassica oleracea L. variety acephala; and yellow rocket, Barbarea vulgaris (R. Br.) variety arcuata in different treatments of planting density, host plant age, intercropping, and water stress in 2003 and 2004. P. x...

Many classification algorithms achieve poor generalization accuracy on “noisy” data sets. We introduce a new non-convex boosting algorithm BrownBoost-δ, a noiseresistant booster, that is able to significantly increase accuracy on a set of noisy classification problems. Our algorithm consistently outperforms the original BrownBoost algorithm, AdaBoost, and LogitBoost on simulated and real data. ...

Recently, it was proposed to use negatively charged electron beams for compensation of beam-beam effects due to protons in the Tevatron collider [1]. We show that a similar compensation is possible in space-charge dominated low energy proton beams. The idea has a potential of several-fold increase of the FNAL Booster beam brightness. Best results will be obtained using three electron lenses aro...

Typical solid rocket motors (SRM) have advantage of their inherent simplicity and reliability, but they do not have the capability to change thrust profile like other propulsion system. Pintle technology is one of the means to achieve variable and programmable thrust. This paper describes a study of the static and dynamic characteristics of a pintle nozzle under the constant mass flow rate. The...

We revisit the top-level ontology Gumo for the uniform management of user and context models in a semantic web environment. We discuss design decisions, while putting the focus on ontological issues. The structural integration into user model servers, especially into the U2M-UserModel&ContextService, is also presented. We show ubiquitous applications using the user model ontology Gumo together ...
