A bit climber using a Gray encoding is guaranteed to converge to a global optimum in fewer than evaluations on unimodal 1-D functions and on multi-dimensional sphere functions, where bits are used to encode the function domain. Exploiting these ideas, we have constructed an algorithm we call Quad Search. Quad Search converges to a local optimum on unimodal 1-D functions in not more than functio...
Ship detection from synthetic aperture radar (SAR) imagery is a fundamental and significant marine mission. It plays an important role in traffic control, fishery management, rescue. Nevertheless, there are still some challenges hindering accuracy improvements of SAR ship detection, e.g., complex background interferences, multi-scale feature differences, indistinctive small features. Therefore,...
QUAD is a provably secure stream cipher, whose security is based on the hardness assumption of solving multivariate quadratic polynomial systems over a finite field, which is known to be NP-complete. However, such provable security comes at a price, and QUAD is slower than most other stream ciphers that do not have security proofs. In this paper, we discuss two efficient parallelization techniq...
An algorithm is described for transforming a quad tree encoding for a picture into a quad tree for the same picture after application of a general linear operator. The technique relies on algorithms and data structures described previously for the construction and superposition of quad trees. The transformation algorithm is shown to take time O(n + sp + mp), where n is the number of nodes in th...
Reverse subdivision constructs a coarse mesh of a model from a finer mesh of this same model. In [1] Lanquetin and Neveu propose a reverse mask for the Catmull-Clark scheme which consists in locally reversing Catmull-Clark original formula for even control points, but this mask can not be applied in reversing other variants such as Quad-averaging scheme of Warren and Weimer [2]. In this paper, ...
We present a survey of ∼800 deg2 of the galactic plane observed with the QUaD telescope. The primary products of the survey are maps of Stokes I, Q, and U parameters at 100 and 150 GHz, with spatial resolution of 5′ and 3.′5, respectively. Two regions are covered, spanning approximately 245◦–295◦ and 315◦–5◦ in the galactic longitude l and −4◦ < b < +4◦ in the galactic latitude b. At 0. ◦02 squ...
The proliferation of contextualized knowledge in the Semantic Web (SW) has led to the popularity of knowledge formats such as quads in the SW community. A quad is an extension of RDF triple with the contextual information of the triple. We in this paper, study the problem of query answering over quads augmented with forall-existential bridge rules that enable interoperability of reasoning betwe...
