Arrays in Blitz++

Numeric arrays in Blitz++ rival the eeciency of Fortran, but without any extensions to the C++ language. Blitz++ has features unavailable in Fortran 90/95, such as arbitrary transpose operations, array renaming, tensor notation, partial reductions, multicomponent arrays and stencil operators. The library handles parsing and analysis of array expressions on its own using the expression templates...

Slammer: The First Blitz Worm

On January 25, 2003, the Slammer worm (also known as Sapphire) exploded on the Internet. Within ten minutes, it had taken over 90% of all unpatched computers running SQL Server or MSDE on the Internet. This article looks at several aspects of the Slammer infestation, including how it spread, the damage it caused, the crisis in vulnerability patching that it underscored, and the implications of ...

Blitz and blizzard: crossbridges and chaos.

The central goal in muscle biophysics is to detect directly the force-generating structural changes of the acto-myosin crossbridge. The principal hypothesis to be tested is that chemical transitions in the ATP hydrolysis cycle are coupled to myosin head rotation between two or more distinct orientations on actin, but a wide range of physical techniques, including electron microscopy, have not p...

BLITZ: Wireless Link Quality Estimation in the Dark

We present BLITZ, a novel link quality estimator that relies on physicallayer synchronization errors to estimate the expected packet delivery ratio of wireless links. In contrast to all existing link quality estimators which estimate the packet delivery based on statistics from packets that are successfully decoded, our technique works even when packets at the receiver are not correctly receive...
