The current best-effort Internet does not guarantee the bandwidth availability between a receiver and a sender, and so renders any quality-of-service (QoS) control difficult, if not impossible. This paper proposes a novel predictive buffering algorithm for streaming video not from one, but from multiple senders to a receiver over the best-effort Internet. In particular, the predictive buffering...

Modern switches and routers often use dynamic RAM (DRAM) in order to provide large buffer storage space. However, the effective bandwidth of DRAM is frequently a limiting factor in the design of high-speed switches and routers. The focus of this paper is to introduce a packet-buffering architecture called the parallel packet buffering (PPB), which increases the effective memory bandwidth signif...

In the present study, asymmetric membrane capsules (AMCs) with two compartments were successfully developed for simultaneous delivery of two poorly water-soluble drugs, Atenolol and Amlodipine Besylate, by using solubility modulation approach. Scanning electron microscopy (SEM) before dissolution showed presence of outer dense region and inner porous region for the prepared asymmetric membrane ...

ad hoc networks are multi-hop wireless networks without a pre-installed infrastructure. such networks are widely used in military applications and in emergency situations as they permit the establishment of a communication network at very short notice with a very low cost. video is very sensitive for packet loss and wireless ad-hoc networks are error prone due to node mobility and weak links. h...

Geolocation techniques aim at determining the geographic location of an Internet host based on its IP address. Currently, measurement-based geolocation techniques disregard the buffering delays that may be introduced at each hop along the path taken by probe packets. To fill this gap, we propose the GeoBuD (Geolocation using Buffering Delay estimation) approach. Although the network delay and t...

In this paper, using a personal computer (PC), the practical implementation of scalar and vector control methods on a three–phase rotor surface- type permanent magnet synchronous machine drive is discussed. Based on the machine dynamic equations and the above control strategies, two block diagrams are presented first for closed-loop speed controlling of the machine drive/system. Then, the desig...
