Granted: 2005-07-12
Abstract: A burial structure (10) providing space for multiple human remains in the form of a body or cremens that has the additional feature of allowing interlocking of the individual units (12). This building feature allows the heretofore unknown ability to form the mausoleum into innovative designs and shapes, from an obelisk shape, like the pyramids of Egypt, to religious symbolisms or aesthetic shapes, thus not solely relying on landscaping for giving beauty and reverence to the mausoleum and its surroundings. Each unit (12) comprises an area (52) for the remains, and alternately an area (50) for any memorabilia to be placed with the remains. Formed of a high-strength synthetic material, the unit (12) is sealed with a cover (34) that has grooves (64) formed therein. The bottom of the unit (12) has corresponding tongues (62), which effect an interlocking relationship. The sides are designed to complement and complete this arrangement. Outer blocks (14), not containing remains, are disposed around the sides and atop the structure.

Title: Preparation of metal-matrix composite materials with high particulate loadings by concentration
Inventor: DOUTRE DON ALLEN
IPC: B22D27/09
Filed: 1999-08-06
Granted: 2005-02-01
Abstract: A composite material having less than about 25 volume percent refractory particles in a metal matrix is concentrated to have about 37-45 volume percent refractory particles. The concentrating is preferably accomplished by heating the composite material to melt the matrix, and then contacting the molten composite material to a porous element having an average pore size greater than that of the average particle size. A small pressure differential, on the order of about one atmosphere, is applied across the porous element, so that metal matrix material separates from the composite material and flows through the porous element. The particulate volume fraction in the composite material gradually increases. When the particulate volume fraction exceeds about 37 volume percent, the mass of composite material becomes semi-solid and freestanding. The resulting composite material may be further processed, as by forming to a useful shape or diluting with another matrix material.

Abstract: L'invention concerne la détection d'intrusions nuisibles ou illégales dans un réseau informatique ou dans des parties réservées dudit réseau, qui consiste à utiliser des analyses statistiques pour comparer des commandes d'utilisateur et des noms de programmes à une séquence modèle. Une correspondance de corrélation et une correspondance de permutation discrètes servent à comparer des séquences. Le résultat de la correspondance est introduit dans un réalisateur de caractéristiques, puis dans un modéliseur pour établir une cote, laquelle permet d'indiquer une intrusion possible. Une séquence de commandes d'utilisateur et de noms de programmes, ainsi qu'une séquence modèle de commandes et de noms de programmes nuisibles provenant de tels modèles sont recherchées. Un facteur de proximité, indiquant la similitude entre la séquence de commandes d'utilisateur et la séquence modèle, est déduit de la comparaison des deux séquences. La séquence de commandes d'utilisateur est comparée à chaque séquence modèle de l'ensemble de modèles. On établit ainsi plusieurs mesures de proximité ou de similitude. L'examen de ces mesures permet de déterminer la séquence modèle qui présente le plus de similitudes avec la séquence de commandes d'utilisateur. Une caractéristique de fréquence, associée à la séquence de commandes d'utilisateur et à la séquence modèle qui présente le plus de similitudes, est calculée. On détermine si la séquence de commandes d'utilisateur constitue une intrusion potentielle dans des parties réservées du réseau informatique en examinant le résultat d'un modéliseur au moyen de la caractéristique de fréquence en tant qu'une entrée.
