Bandwidth smoothing techniques for the delivery of compressed prerecorded video have been shown effective in removing the burstiness required for the continuous playback of stored video. Given a fixed client-side buffer, several bandwidth smoothing algorithms have been introduced that are provably optimal under certain constraints. These algorithms, however, may be too aggressive in the amount ...

Techset Com Reliability for network-on-chips has been widely researched in last decades not only to support the rapid growing requirement of onchip communication but also to address the challenge on reliability due to aggressive technology scaling. Simulation is the most common method to evaluate the capacity of reliability design but its cost is significant. Therefore, it is necessary to calcu...

We consider rate-distortion (RD) optimized multi-flow video delivery in unstructured overlay networks. We show that this problem can be studied as a distributed rate allocation. To solve the problem over the participating peers in the overlay, we apply classical decomposition techniques such that the network-wide utility of video distortion is minimized. Media packets are assumed to be piggy-ba...

The emerging technology of drug-encapsulated nanoparticles plays a critical role in the development of treatment for various life-threatening diseases due to the versatility, control, and future potential of the design of these systems. A current treatment technique for the treatment of brain tumor cells, after major surgery, utilizes a drug adhered to a biodegradable polymer wafer that provide...

OBJECTIVE To examine physician-documented indications for cesarean delivery in order to investigate the specific factors contributing to the increasing cesarean delivery rate. METHODS We analyzed rates of primary and repeat cesarean delivery, including indications for the procedure, among 32,443 live births at a major academic hospital between 2003 and 2009. Time trends for each indication we...

For contents delivery systems such as video-ondemand service, an optimum design is presented to maximize the utility of the system with priority classes. The willingness-to-pay (WTP) is introduced for a measure of utility, and the optimum design is discussed to maximize the utility (revenue). For the system with two priority classes, the optimum condition is given in terms of the traffic load, ...

Today there are many services which provide information over the phone using a prerecorded or synthesized voice. These voices are invariant in speed. Humans giving information over the telephone, however, tend to adapt the speed of their presentation to suit the needs of the listener. This paper presents a preliminary model of this adaptation. In a corpus of simulated directory assistance dialo...

OBJECTIVE To determine if there are monthly variations in the rate of deliveries in Benin City, Nigeria. MATERIALS AND METHODS A retrospective descriptive study carried out in the three major obstetric centers in Benin City, Nigeria. We extracted the total number of deliveries from the hospitals' records for over a five-year period and analyzed the figures for monthly variation in delivery ra...

Removal of insulin-(131)I from plasma was studied in normal and diabetic subjects with both single injection and continuous infusion of isotope techniques. Patients were studied either in the fasting state or during steady-state hyperglycemia produced by a continuous intravenous glucose infusion. Steady-state plasma insulin concentration during these studies ranged from 10 to 264 muU/ml. Labele...

Variable-bit-rate (VBR) encoding is known to provide a more consistent visual quality compared to constant-bit-rate (CBR) encoding. However, the resultant bit-rate variations greatly complicated the allocation of disk and network bandwidth in a video-on-demand system. This paper investigates a new scheduling algorithm with monotonic-decreasing rate allocations for scheduling disk retrievals and...
