Performance studies, linking ATM switch capabilities to physical limitations imposed by integrated circuit technology, have been scarce. This paper explores trends in circuit capabilities, and makes projections toward the 0.25m technologies that will be available to all switch designers in the year 2000. The limits imposed by circuit technology are applied to shared buffer ATM switches. We dete...

In this work, the peak rate of the caching problem is investigated, under the scenario that the users are with small buffer sizes and the number of users is no less than the amount of files in the server. A novel coded caching strategy is proposed for such a scenario, leading to a lower peak rate compared to recent results in the literature. Furthermore, it is verified that our peak rates coinc...

A new sensitive, simple and rapid method for determination of methotrexate (MTX) was developed based on quenching effects of MTX on the fluorescence intensity of Tb3+-1,10-phenanthroline complex. The fluorescence intensity was measured with excitation wavelength of 300 nm and emission wavelength of 545 nm and the quenched fluorescence intensity is proportional to the concentration of MTX in Tris...

In a field experiment that constructs randomized credit limit shock, participants borrow to spend 11 cents on the dollar in first quarter and 28 by third year. Effects extend those far from limit, who had new limits as available credit, with liquid asset buffer. short-run, flexible installment contracts are used tandem, unconstrained using installments more. Long-run borrowing is predominantly ...

two capillary zone electrophoresis (cze) methods were developed in this study, one using an acidic buffer (sodium citrate ph = 2.5) and the other using a basic buffer (sodium tetraborate ph = 9.8). the two methods were compared on the basis of repeatability and reproducibility of results and the cze method developed with the basic buffer was then selected for further studies. the method was ful...

Limit energy is a severe bottleneck of wireless sensor networks (WSNs), and limits network lifetime of WSNs. To extend network lifetime, buffer zone has been proposed. Sensors send their data packets to buffer zone. The sensors in buffer zone buffer the data packets. And then the sink visits the buffer zone to collect the data packets. This leads to that the loads of the sensors in buffer zone ...

BACKGROUND Given that Δ(9)-tetrahydrocannabinol, the active constituent of cannabis, has been shown to greatly reduce driving ability, thus being linked to many drug driving accidents, its reliable detection is of great importance. RESULTS An optimised carbon paste electrode, fabricated from graphite powder and mineral oil, is utilised for the sensitive detection of Δ(9)-tetrahydrocannabinol ...

One of the scarce resources that limits communication performance is buffer space on the network interface card. This becomes even worse when it is partitioned among several time-sliced processes. However, if gang scheduling is used, it is possible to swap buffer contents as part of the context switch, giving each job the full buffer space for the duration of its quantum. This does not suffer u...
