The formation of a recrystallization texture is closely related to the nucleation and growth of recrystallizing grains, which may vary from grain to grain. Cube texture is a commonly observed recrystallization texture in face centered cubic metals of medium to high stacking fault energy after heavy cold-rolling and annealing. In this work, recrystallization of pure copper cold-rolled to a von M...

OLAP applications use precomputation of aggregate data to improve query response time. While this problem has been well-studied in the recent database literature, to our knowledge all previous work has focussed on the special case in which all aggregates are computed from a single cube (in a star schema, this corresponds to there being a single fact table). This is unfortunate, because many rea...

CRYPTO 2008 saw the introduction of the hash function MD6 and of cube attacks, a type of algebraic attack applicable to cryptographic functions having a low-degree algebraic normal form over GF(2). This paper applies cube attacks to reduced round MD6, finding the full 128-bit key of a 14-round MD6 with complexity 2 (which takes less than a minute on a single PC). This is the best key recovery a...

The data cube is an aggregate operator which has been shown to be very powerful for On Line Analytical Processing (OLAP) in the context of data warehousing. It is, however, very expensive to compute, access, and maintain. In this paper we de ne the \cubetree" as a storage abstraction of the cube and realize it using packed R-trees for most e cient cube queries. We then reduce the problem of cre...

RÉSUMÉ. De nombreuses approches ont proposé de pré-calculer des cubes de données afin de répondre efficacement aux requêtes OLAP. La notion de cube de données a été déclinée de différentes manières : cubes icebergs, cubes intervallaires ou encore cubes différentiels. Dans cet article, nous introduisons le concept de cube convexe qui permet de capturer tous les tuples d’un cube de données satisf...

In this paper we develop a representational approach to media theory. We construct representations of media by well-graded families of sets and partial cubes and establish the uniqueness of these representations. Two particular examples of media are also described in detail. © 2007 Elsevier B.V. All rights reserved.

In the n-dimensional cube, we determine the maximum size of antichains having a lower shadow of exactly m elements in the k-th level.

An incomplete data cube is a multidimensional hierarchy of aggregate values in which regions of the hierarchy, and the source data from which those regions are derived, are missing. We model an incomplete cube as a collection of complete sub-cubes called cubettes. Each cubette is deened using a precise, simple speciication. The set of cubette speciications concisely characterises the informatio...

In this paper we propose a tangible cube as an input device for playfully changing between different TV-channels. First we consider several design approaches and compare them. Based on a cube that has embedded gravity sensing and wireless communication capabilities a prototype is implemented. A 3D graphical representation of the cube is shown on the television screen. On each face of the cube a...

PURPOSE The aim of this study was to investigate factors associated with the signal strengths (SS, image quality scores) of optic disc and macular images obtained using Cirrus spectral domain optical coherence tomography (OCT). METHODS Ninety-two glaucomatous eyes were imaged using the Cirrus OCT macular and optic disc cube modes after pupil dilation. The influences of patient age, spherical ...
