In this paper we present PLF (Promotion of Long Flows). PLF tries to promote web traffic using the Token Bucket Model in a DiffServ framework. This algorithm preserves the high priority for short flows but tries to allocate some long flows in the high priority class level, in order to improve some performance parameters of the long ones. Finally, we present PLFwp (Promotion of Long Flows with P...

Many studies explored the guaranteed TCP throughput problem in DiffServ networks. Several new marking schemes have been proposed in order to solve this problem. Even if these marking schemes give good results in the case of per-flow conditioning, they need complex measurements. In this paper we propose a conditioning method to reduce these complex measurements and an AIMD Penalty Shaper (APS) w...

Mashups are getting more complex with the addition of rich-media and real-time services. The new research challenges will be how to guarantee the quality of the aggregated services and how to share them in a collaborative manner. This paper presents a metadata-based mashup framework in Next Generation Wireless Network (NGWN), which guarantees the quality and supports social interactions. In con...

The outsource data backup to third-party cloud storage services so as to reduce data management costs, security concerns arise in terms of ensuring the privacy and integrity of out-sourced data. Design Policy Base a practical, implementable, and readily deployable cloud storage system that focuses on protecting deleted data with Policy Based file secured deletion. Policy Base is built upon stan...

Federally funded, multistate field studies were initiated in 2002 to measure emissions of particulate matter (PM) < 10 microm (PM10) and total suspended particulate (TSP), ammonia, hydrogen sulfide, carbon dioxide, methane, nonmethane hydrocarbons, and odor from swine and poultry production buildings in the United States. This paper describes the use of a continuous PM analyzer based on the tap...

Differentiated Service networks (DS) are fair in the way that different types of traffic can be associated to different network services, and so to different quality levels. However, fairness among flows sharing the same service may not be provided. Our goal is to study fairness between multirate multimedia sessions for an assured DS service, in a multicast network environment. To achieve this ...

BACKGROUND The Scholars in Rural Health program is designed to attract and retain young rural Kansans with a high probability of successful careers in rural communities. This program shapes the students' experiences toward rural health in preparation for entry into medical school. Scholars accepted into and satisfactorily completing this program are admitted automatically to the School of Medic...

As previously reported, a novel low temperature (LoTemp) polymerase chain reaction (PCR) catalyzed by a moderately heat-resistant (MHR) DNA polymerase with a chemical-assisted denaturation temperature set at 85 °C instead of the conventional 94-96 °C can achieve high-fidelity DNA amplification of a target DNA, even after up to 120 PCR thermal cycles. Furthermore, such accurate amplification is ...
