In order to provide QoS in group communications for real time applications such as video conferencing, reliable multicasting is used. Miscellaneous efforts have been undertaken to provide reliability on top of IP multicast. In this paper, we present a new fair share policy (FSP) that utilizes Differentiated Services to solve the problems of QoS and congestion control when reliable FEC multicast...

Endothelialization of expanded polytetrafluoroethylene (ePTFE) has the potential to improve long-term patency for small-diameter vascular grafts. Successful endothelialization requires ePTFE surface modification to permit cell attachment to this otherwise non-adhesive substrate. We report here on a peptide fluorosurfactant polymer (FSP) biomimetic construct that promotes endothelial cell (EC)-s...

Friction stir processing (FSP) is a novel method of metal surface modification during the process by addition strengthening particles. FSP produced refined microstructures with development added ceramic particles on metal. In this FSP, mechanical characteristics were enhanced parameters, tool spinning speed, traverse speed and axial force high carbon chromium die steel (non-consumable tool). re...

Induced resistance is an important component of disease-resistance response of plants, and is accompanied by increased capability for activating defense responses upon pathogen ingress or elicitor treatment. Aqueous leaf extract of neem (Azadirachta indica Juss.) provided the control of Alternaria leaf spot pathogen (Alternaria sesami) of sesame (Sesamum indicum L: Syn. S. orientale L). Treatme...

Silica particles were prepared by flame spray pyrolysis (FSP) as a support for nickel catalysts. The impact of precursor feed rate (3, 5 and 7 mL/min) during FSP on the silica characteristics and the ensuing effect on catalytic performance for the carbon dioxide, or dry, reforming of methane (DRM) was probed. Increasing the precursor feed rate: (i) progressively lowered the silica surface area ...

Considered is a 2D cellular automaton with moving agents. The objective is to find agents controlled by a Finite State Program (FSP) that can form domino patterns. The quality of a formed pattern is measured by the degree of order computed by counting matching 3 × 3 patterns (templates). The class of domino patterns is defined by four templates. An agent reacts on its own color, the color in fr...

A fundamental problem for peer-to-peer systems is to maintain connectivity while nodes are leaving, i.e., the nodes requesting to leave the peer-topeer system are excluded from the overlay network without affecting its connectivity. There are a number of studies for safe node exclusion if the overlay is in a well-defined state initially. Surprisingly, the problem has not been formally studied y...

Long-time average spectrum (LTAS) was used to analyze the cry utterance of 26 infants under four months old; 16 of them were full-term and the other 10 infants were preterm. The results of first spectral peak (FSP), mean spectral energy (MSE), spectral tilt (ST), high frequency energy (HFE) were used to compare the cry production between term and preterm infants. In addition, cry duration and p...

Introduction: Tomato production in Ethiopia is challenged by many pests and diseases. Fusarium wilt one of the most important diseases tomato affecting its productivity. Methods: tissue soil samples were collected from farmlands around Aksum town to isolate identify pathogenic species Trichoderma with biocontrol efficacy. Samples processed University Biotechnology laboratory following standard ...
