This article reviews information from published papers and studies by the authors about placer diamond deposits. Original data were obtained in result of field laboratory-analytical work carried out various countries Africa South America. The main types deposits – fluvial, fluvioglacial, eolian, man-made have been considered characterized. attention is given to fluvial continental placers, whic...

<p align="justify">El concepto tradicional de arte está estrechamente relacionado con la belleza y también el placer estético. Sin embargo, aparición del vanguardia contemporáneo ha subvertido dicha imaginación. El ya no parece ser agradable, pero puede repugnante más a menudo se critica como aburrido. Desde tal punto vista, este artículo busca las razones por que aburre sus espectadores....

RÉSUMÉ. Des modèles pour placer les données des familles de genes individuelles sur un arbre d'espèces évolutionnaires sont presentés. Une famille de gènes est, tipiquement, observée comme un ensemble de proteins homologue, qui appartient aux espèces differentes, qui veut dire que des données dans la forme de (a) une matrice de distance entre protéines, ou (b) un arbre de "gènes", dérivé de cet...

We describe the Trianus software system which consists of a suite of tightly integrated tools for the eecient design and implementation of algorithms using a custom computing machine. The software is built upon a generic framework for FPGA circuit design and comprises a compiler for the Lola hardware description language, a layout editor, a circuit checker, a technology mapper, a placer, a rout...

The MINCE heuristic for variable-ordering [1] can successfully reduce the size of BDDs and accelerate SAT-solving. Applications to reachability analysis have also been successful [12]. The main drawback of MINCE is its implementation complexity the authors used a pre-existing min-cut placer [6] that is several times larger than any existing SAT solver. Tweaking MINCE is difficult. In this work ...

This work presents the Agents 2 system, developed using software agent technology and the Java language, to automate the generation of VLSI leaf cells. It also highlights the interconnection prediction methods used in the system and show how they contribute to help layout generation. Many agents (implemented as servers) compose the Agents2 system: one Placer server (to place the cell’s componen...
