Most existing alias analysis techniques are formulated in terms of high-level language constructs and are unable to cope with pointer arithmetic. For machines that do not have ’base + offset’ addressing mode, pointer arithmetic is necessary to compute a pointer to the desired address. Most state of the art compilers such as GCC lack the mechanism to determine aliasing between such computed poin...

Computer generated animation is widespread in lms, television commercials , multimedia and games. The availability of powerful modeling and animation packages has contributed greatly to this popularity and has been instrumental in bringing computer animation into the mainstream. These packages work primarily with polygonal representations of models. Deformation for animation is achieved by mean...

External iterators pose problems for alias control mechanisms: they have access to collection interals and yet are not accessible from the collection; they may be used in contexts that are unaware of the collection. And yet iterators can benefit from alias control because iterators may fail “unexpectedly” when their collections are modified. We explain a novel aliasing annotation “from” that in...

An active filter with a 50 Ω buffer suitable as an anti-alias filter to drive a highly linear ADC is implemented in 0.13 μm SiGe BiCMOS. This 6th-order Chebyshev filter has a 3 dB cutoff frequency of 28.3 MHz and achieves 36.5 dBm OIP3. Nonlinear digital equalization further improves OIP3 to 43.6 dBm. Measurements show 92 dB of rejection at the stopband and a gain of 49 dB. The measured in-band...

In this article we investigate two-level split-plot designs where the sub-plots consist of only two mirror image trials. Assuming third and higher order interactions negligible, we show that these designs divide the estimated effects into two orthogonal sub-spaces, separating sub-plot main effects and sub-plot by whole-plot interactions from the rest. Further we show how to construct split-plot...

UNLABELLED Redundancy among sequence identifiers is a recurring problem in bioinformatics. Here, we present a rapid and efficient method of fingerprinting identifiers to ascertain whether two or more aliases are identical. A number of tools and approaches have been developed to resolve differing names for the same genes and proteins, however, these methods each have their own limitations associ...

Peripheral resolution acuity for achromatic gratings is known to be limited by the density of the underlying ganglion cell sampling array. After confirming isolation of the short-wavelength sensitive (SWS) system using chromatic adaptation methods, we wished to determine if resolution is limited by blue/yellow ganglion cell sampling (evidenced by a superiority of detection over resolution acuit...
