Modeling Mechanical DAE Using Natural Coordinates

Synthesis of Some Mechanisms Using Natural Coordinates

The aim of this article is to demonstrate the kinematical synthesis of some mechanisms applied in agricultural machineries. The applied method based on the use of natural coordinates for this reason the method is simple and efficient. The mechanical system is described by a set of geometric constraints. The design requirements are handled by a set of functional constraints. By the aid of object...

Mechanical signaling coordinates the embryonic heartbeat.

In the beating heart, cardiac myocytes (CMs) contract in a coordinated fashion, generating contractile wave fronts that propagate through the heart with each beat. Coordinating this wave front requires fast and robust signaling mechanisms between CMs. The primary signaling mechanism has long been identified as electrical: gap junctions conduct ions between CMs, triggering membrane depolarizatio...

Modeling Legislation Using Natural Language Processing

$EVWUDFW This paper describes the possibilities of the translation of legislation, which is written in natural language, into a formal language, i.e. UML/OCL. The tool OPAL (Object-oriented Parsing and Analysis of Legislation) is developed to support the automatic modelling of legislation with the use of appropriate NLP techniques. The aim is not to perform this modelling in a batch fashion fro...

Geometric Modeling without Coordinates and Indices

Since Descartes, coordinates have been the standard mathematical construct for describing and manipulating geometric objects. In addition, indices are commonly used to label elements of discrete geometric structures, such as polygon meshes. Since the coordinates and indices are numbers, they can be manipulated algebraically. This sets the framework for the handling of geometric objects in algeb...
