Customer Relationship Management (CRM)1 has been discussed in the literature since the nineties. IT evaluation on the other hand dates back to the eighties starting with a more contemporary approach (Farbey et al. 1999, p. 191). As reported by earlier works, the success rate of CRM implementation projects is up to today still not satisfactory (Becker et al. 2009; Finnegan and Currie 2009). Reas...

This may seem strange, but it is true: almost everything you do is controlled by your brain, even things you might not “think” about. For example, if you sit down to do some particularly difficult math homework, the parts of your brain that allow you to manipulate numbers and solve problems, like the prefrontal cortex, will be working in overdrive. But even for relatively “simple” things, like ...

Genetic Algorithms (GAs) are direct searching methods which require little information from design space. This characteristic beside robustness of these algorithms makes them to be very popular in recent decades. On the other hand, while this method is employed, there is no guarantee to achieve optimum results. This obliged designer to run such algorithms more than one time to achieve more reli...

Introduction: Unsupervised object discovery (UOD) is the task of finding repeating patterns and common visual concepts across an unsorted set of images without any human supervision. These concepts should describe objects, like pedestrians or cars, and stuff, like road or sky. Once discovered, this information opens several interesting applications like summarization and filtering of visual con...

We present a general method of generating continuous fractal interpolation surfaces by iterated function systems on an arbitrary data set over rectangular grids and estimate their Box-counting dimension.

An optimal box-counting algorithm for estimating the fractal dimension of a nonempty set which changes over time is given. This nonstationary environment is characterized by the insertion of new points into the set and in many cases the deletion of some existing points from the set. In this setting, the issue at hand is to update the box-counting result at appropriate time intervals with low co...

As evidence from recent years has demonstrated, box-counting provides an objective fractal analytical method to evaluate the visual complexity of architecture. This paper for the first time explores the potential of box-counting with regard to the work of the Viennese architect Adolf Loos (1870-1933). Loos is seen as the pioneer of modern architecture, as someone who anticipated the Internation...

The southern CfA2 galaxy data are used to investigate the scaling properties of the galaxy number distribution. We construct two volume-limited samples with galaxy magnitudesMB(0) ≤ −19.42 andMB(0) ≤ −20.00, and calculate the secondto ninth-order moments with the box-counting method. On scales from 5 to 27 h−1 Mpc, the moments exhibit multifractal scalings. From the exponents of the scalings, w...

The objective of this paper is to examine the development of the urban form of the city of Olomouc since the 1920s in terms of fractal dimension, and to link the observation with two other descriptors of shape – area and perimeter. The fractal dimension of built-up areas and fractal dimension of the boundary of the city are calculated employing the box-counting method; the possibilities of thei...
