As a first step in the classification of all thick Moufang polygons, it is shown that every root ray datum of type Ã2, B̃2 or G̃2 has a filtration by an ordinary root datum.

We give a short overview on methods of Model (In-)Validation, that fit to the robust control framework. The idea is that the mismatch between a measured datum and an expected datum is explained by a disturbance signal w and an error model ∆, representing unmodelled dynamics. The key question is if there exists a pair (w,∆), sufficiently small, that can produce the measured datum. In particular,...

A novel concept of neural force position control in cartesian space NFC was developed and applied The NFC concept for a DOF industrial robot with DOF sensor forces torques is based on a cycle time of only msec NFC features include Sensor and trajectory data processing in cartesian space Learned mapping operations for force kinematics and dynamics with neural networks Singularity robust ness in ...

Purpose: Dynamic contrast enhanced MRI (DCEMRI) and MR angiography (MRA) are both beset by the conflicting requirements of spatial and temporal resolution. Various schemes have been proposed and evaluated for high spatio-temporal resolution MR imaging [1-4]. They all incorporate combinations of partial Fourier imaging, sub-sampling, view sharing and parallel imaging to effect acceleration. The ...

The cellular automata (CA) model combining topological deformation and adaptive activation energy was successfully constructed to analyze the thermal dynamic recrystallization of magnesium alloy (AZ61). simulation datum shown that nucleation located on grain boundary (GB) once density dislocation accumulated specific value, result presents a typical characteristics i.e., repeated growth. result...

Sparse Distributed Memory (or Kanerva Networks) is a technique first introduced as a model of memory in neuroscience, [2] (see also §13 of [1] for a quick summary). In a large Boolean space F2 one chooses a uniform random sample of hard locations. The number 2k of hard locations is small compared to the size 2N of the ambient space. At each of these hard locations a datum (a Boolean string of l...

This paper describes a new parallel kinematic architecture for machining applications, namely, the orthoglide. This machine features three fixed parallel linear joints which are mounted orthogonally and a mobile platform which moves in the Cartesian x-y-z space with fixed orientation. The main interest of the orthoglide is that it takes benefit from the advantages of the popular PPP serial mach...

The set of coordinates used to describe the motion of a dynamic system is not unique. For example, consider an elastic pendulum (a mass on the end of a spring). The position of the mass at any point in time may be expressed in Cartesian coordinates (x(t), y(t)) or in terms of the angle of the pendulum and the stretch of the spring (θ(t), u(t)). Of course, these two coordinate systems are relate...

one of the most important problems in geodesy is the unification of height datum. generally in geodesy; there are two types of height systems, the geometrical height based on ellipsoid and the physical height based on gravity-defined surface (zhang et al, 2009).local height datum is determined according to mean sea level (msl). in regarding to mismatch of mean sea level and geoid, on the one ha...
