In this paper, the relation between hlock digital filtering and quadrature mirror filter (QMF) hanks is explored. Necessary and sufficient conditions for alias cancellation in QMF hanks are expressed in terms of an associated matrix, derived from the polyphase components of the analysis and synthesis filters. These conditions, called the pseudocirculant conditions, enahle us to directly unite Q...

UNLABELLED AliasServer provides services that facilitate the assembly of data or datasets that make use of different identifiers for refering to the same protein. This resource relies on a database which contains, for a given organism, a non-redundant list of protein sequences associated with a set of aliases. AVAILABILITY AliasServer is available as an interactive Web server at http://cbi.la...

Nowadays error checking becomes more and more significant for constructing high reliable software. In this paper, we will introduce our work of integrating static error checking into Open64. We are devoting to construct an aggressive program analysis framework for error checking in the compiler. We integrate the intraprocedural analysis into interprocedural phase in order to do flowand contexts...

A non-uniform additive pseudo-random sampling pattern (mainly proposed in the signal processing communities) can be used for performing an ‘alias-free signal sampling’ process. The carefully designed sampling scheme can mitigate the effects of aliasing and permit significant reductions in the average sampling frequency, leading to more efficient processor utilization. Despite the fact that the ...

Based on a generalized framework for alias free QMF banks, a theory is developed for the design of uniform QMF banks with real-coefficient analysis filters, such that aliasing can be completely canceled by appropriate choice of real-coefficient synthesis filters. These results are then applied for the derivation of closed-form expressions for the synthesis filters (both FIR and RR), that ensure...

We show that breadth-first traversal exploits the difference between the static delimited-control operator shift (alias S) and the dynamic delimited-control operator control (alias F). For the last 15 years, this difference has been repeatedly mentioned in the literature but it has only been illustrated with one-line toy examples. Breadth-first traversal fills this vacuum. We also point out whe...

Discovering router-level IPv6 topologies is important to understanding IPv6 growth, structure, and evolution and relation to IPv4. This work presents a fingerprint-based IPv6 alias resolution technique that induces fragmented responses from IPv6 router interfaces. We leverage the way in which IPv6 implements fragmentation to provide reliable inferences. We demonstrate perfect alias resolution a...
