Today, because of TCP dynamics, Internet backbone routers hold large packet buffers, which significantly increase their power consumption and design time. Recent models of large-buffer networks have suggested that these large buffers could be replaced with much smaller ones. Unfortunately, it turns out that these largebuffer network models are not valid anymore in small-buffer networks, and the...

A common approach in resolving enantiomers of chiral basic drugs by capillary electrophoresis (CE) is to use cyclodextrins (especially their anionic derivatives) as chiral selector in the acidic buffer (pH ≤ 3) in normal or reversed (carrier) mode. Then, some organic modifiers are added to the buffer solution if the resolution is not satisfactory. In case of cetirizine (CTN), applying the same ...

Buffer overflow attacks cause serious security problems. Array & pointer bound checking is one of the most effective approaches for defending against buffer overflow attacks when source code is available. However, original array & pointer bound checking causes too much overhead since it is designed to catch memory errors and it puts too many checks. In this paper, we propose an efficient array ...

In recent years, there has been a lot of interest in Quality of Service (QoS) networks. In regular IP networks, packets are indistinguishable and in case of overload any packet may be dropped. In a commercial environment, it is much more preferable to allow better service to higher-paying customers or customers with critical requirements. The idea of Quality of Service guarantees is that packet...

In this paper, we propose the concept of using query execution feedback for improving database buffer management. A query feedback model which adaptively quantifies the page fault characteristics of all query access patterns including sequential, looping and most importantly random, is defined. Based on this model, a load control and a marginal gain ratio buffer allocation scheme are developed....

We consider simulation games played between Spoiler and Duplicator on two Büchi automata in which the choices made by Spoiler can be buffered by Duplicator in two different buffers before she executes them on her structure. Previous work on such games using a single buffer has shown that they are useful to approximate language inclusion problems. We study the decidability and complexity and sho...

The geometric buffer (G-buffer) is a well-known approach to implement imagebased rendering algorithms. We propose a framework that maps the G-buffer concept and associated image-space operations to the graphics processing unit (GPU). This GPU-G-buffer (G-buffer) framework consists of two major components: first, a texture-based representation of the G-buffer attributes; second, an implementatio...

Riparian buffer strips are a widely accepted tool for helping to sustain aquatic ecosystems and to protect downstream resources and values in forested areas, but controversy persists over how wide a buffer strip is necessary. The physical integrity of stream channels is expected to be sustained if the characteristics and rates of tree fall along buffered reaches are similar to those in undistur...

Communication latencies have been identified as one of the performance limiting factors of message passing applications in clusters of workstations/multiprocessors. On the receiver side, message-copying operations contribute to these communication latencies. Recently, prediction of MPI messages has been proposed as part of the design of a zero message-copying mechanism. Until now, prediction wa...
