Network intrusion detection systems (NIDS) are becoming an important tool for protecting critical information and infrastructure. The quality of a NIDS is described by the percentage of true attacks detected combined with the number of false alerts. However, even a high-quality NIDS algorithm is not effective if its processing cost is too high, since the(More)
The primary objective of this paper is to explain the derivation of symplectic mollified Verlet-I/r-RESPA (MOLLY) methods that overcome linear and nonlinear instabilities that arise as numerical artifacts in Verlet-I/r-RESPA. These methods allow for lengthening of the longest time step used in molecular dynamics (MD). We provide evidence that MOLLY methods(More)
As a result of technology trends towards multi-gigahertz processors, the I/O system is becoming a critical bottleneck for many applications. Interrupts are a major aspect of most device drivers. Characterizing interrupt performance and its relation to architectural trends is important for understanding and improving I/O subsystem performance. Kernel(More)
One of the major design decisions when developing a new microprocessor is determining the target pipeline depth and clock rate since both factors interact closely with one another. The optimal pipeline depth of a processor has been studied before, but the impact of the memory system on pipeline performance has received less attention. This study analyzes(More)
In perfusion fixation of dog kidney glomeruli, observation of tear fractured surfaces by scanning electron microscopy reveals the deposition of "debris" on the surface of glomerular visceral epithelium (podocytes) that is not deposited on other kidney tissue surfaces. It is of concern to remove this debris without damage to tissue surfaces. A 5 minute bath(More)
Corrosion casts of the plastic (Mercox Cl-2B) filled pig kidney cortex vasculature were sliced either parallel or perpendicular to the kidney surface. Scanning electron microscopy photographs were taken of the casts. Montages of the photographs were analyzed using a digitizing tablet and microcomputer-based software. For vessels having diameters larger than(More)
Pig kidney glomerular vascular anatomy was studied by scanning electron microscopy of vascular corrosion casts. A generalized vascular architecture is presented to describe the pig kidney glomerulus based upon the observation of 3,800 vascular cast glomeruli. The relative simplicity of the pig glomerular vascular architecture has allowed the(More)
