Automatic generating of theorems and constructing models for projective geometry

The paper discusses the use of computers to construct models and generate theorems of projective geometry. After signalising the history of the issue, the axiomatics as well as basic properties of projective geometry have been introduced. The main body of the paper constitutes a proposed and discussed idea of building a plane by implementing axioms. As an essential extension, the theorems are p...

Mesh-Based Geometry: A Systematic Approach To Constructing Geometry From A Finite Element Mesh

A new system for defining geometry based on feature s of a finite element mesh is described. A systemat ic approach to building a complete geometric and topologic representation of a model given only the finite element description i s proposed. Geometry and topology entities including volumes, surfaces, curv es and vertices, can be implied based on user defin ed boundary conditions or surface f...

Background: Proteins of various compositions are required by organisms inhabiting different environments. The energetic demands for protein formation are a function of the compositions of proteins as well as geochemical variables including temperature, pressure, oxygen fugacity and pH. The purpose of this study was to explore the dependence of metastable equilibrium states of protein systems on...

Geochemical Transactions

The geochemical discriminate diagrams help to distinguish the volcanics recovered from different tectonic settings but these diagrams tend to group the ocean floor basalts (OFB) under one class i.e., as mid-oceanic ridge basalts (MORB). Hence, a method is specifically needed to identify the OFB as normal (N-MORB), enriched (E-MORB) and ocean island basalts (OIB). We have applied Artificial Neur...

Geochemical Partitioning in Till

and Vagners (1971, 1972) expressed this phenomenon elegantly by introducing the concept of "terminal mode" for the optimum grain size to which a mineral can be reduced, given the force and energy typically available in the glacial environment. Thus, hard, uncleaved or poorly cleaved minerals such as quartz, fcldspar, garnet, pyrite and magnetite dominate either the medium or the fine sand fract...
