This research extends on previous work which has its origin in a method, Space Syntax Analysis [2], to describe and analyse patterns of architectural space – both at the building and urban level. In the process of applying space syntax analysis [3] the space (roads, parks, etc.) in the town is partitioned into the smallest number of convex polygons to cover the whole town. Then the axial lines ...

Factorial clustering methods have been developed in recent years thanks to the improving of computational power. These methods perform a linear transformation of data and a clustering on transformed data optimizing a common criterion. Factor PD-clustering is based on Probabilistic Distance clustering (PD-clustering). PD-clustering is an iterative, distribution free, probabilistic, clustering me...

Although the Symmetrical Component Transformation has existed for 80 years, its application in the time-dependent form is practically restricted to the electric-machine theory. In the Power Systems field one uses the transformation applied to gteady-state ginusoidal phasors in a nonunitary form for fault calculations. For time-domain calculations the real equivalat, 0, , , is preferred, usually...

Although model transformations presumably play a major role in Model-Driven Engineering, reuse mechanisms such as inheritance have received little attention so far. In this paper, we propose a comparison framework for rule inheritance in declarative model-to-model transformation languages, and provide an in-depth evaluation of three prominent representatives thereof, namely ATL, ETL (declarativ...

OBJECTIVE The specificity of magnetic resonance imaging (MRI)-based hippocampal measurements in detecting Alzheimer's disease (AD) pathology is reduced by an age-related reduction of the hippocampus volume. We propose an adjustment for this age effect to increase the diagnostic accuracy of hippocampal volumes in AD. METHOD Using an orthogonal rotational transformation of the coordinate system...

The reliability of traditional photogrammetric identification techniques using a small number of facial landmarks has recently come in for criticism. However, the transformation of parameters into a new face space in which the error distributions are orthogonal, yields a maximum likelihood solution to the problem of identifying a photographed face from a small, known, population which, in a sim...

This paper considers a two-level atom interacting with two cavity modes with equal frequencies. Applying a unitary transformation, the system reduces to the analytically solvable Jaynes-Cummings model. For some particular field states, coherent and squeezed states, the transformation between the two bare basis's, related by the unitary transformation, becomes particularly simple. It is shown ho...

Maxwell’s curl equations are formulated in curvilinear non-orthogonal coordinates in three dimensions in a manner that enables to preserve conventional Cartesian mesh for the finite-difference schemes by means of mere redefinition of the permittivity and permeability coefficients. It is highlighted that in the previous works on this subject (Ward and Pendry 1996 J. Modern Opt. 43 773; 1998 Phys...
