2,3,7,8-tetrachlorodibenzo-p-dioxin (tcdd) is a by-product o f t he trichlorophenol (herbicide) production and is also produced through a variety of combustion processes. it appears that tcdd is a ubiquitous chemical, particularly in industrialised countries, and the liver is the target organ of its toxicity. the prominent hepatotoxic effect of tcdd is progressive centrilobular necrosis. the is...

Modern reorder buffers (ROBs) were conceived to improve processor performance by allowing instruction execution out of the original program order and run ahead of sequential instruction code exploiting existing instruction level parallelism (ILP). The ROB is a functional structure of a processor execution engine that supports speculative execution, physical register recycling, and precise excep...

Buffer overflows have become the most common target for network-based attacks. They are also the primary propagation mechanism used by worms. Although many techniques (such as StackGuard) have been developed to protect servers from being compromised by buffer overflow attacks, these techniques cause the server to crash. In the face of automated, repetitive attacks such as those due to worms, th...

This work introduces S-buffer, an efficient and memory-friendly gpu-accelerated A-buffer architecture for multifragment rendering. Memory is organized into variable contiguous regions for each pixel, thus avoiding limitations set in linked-lists and fixed-array techniques. S-buffer exploits fragment distribution for precise allocation of the needed storage and pixel sparsity (empty pixel ratio)...

Repeaters are widely used to combat the quadratic delay of long on-chip wires. A conventional repeater is a CMOS inverter placed periodically along the long wire. This design has two drawbacks. The wire must have an even number of repeaters to preserve signal polarity. This forces the designer to sometimes use a suboptimal number of repeaters. It is also awkward when a wire branches because rep...

In this paper, many details of database buffer management including goals, roles, organization, and schemes are discussed. There is a focus on the LRU-K scheme and its features.
