Glorious Fonts, a new graphically-based font type, allow interesting effects to be applied to existing character sets. The difficulties of automating this process are examined in the context of applying Celtic knotwork designs to plain text characters. An analysis of knotwork construction techniques shows how complete designs may be described by an expanded tile set. This paper also presents an...

Abstract—Modeling artificial societies that form an economy can add to our understanding of modern economic theory. A case of interest is the Sugarscape model developed by Joshua M. Epstein and Robert Axtell. In many respects, Sugarscape exhibits emergent behaviors that adhere to neoclassical economics; however, other behaviors of the model do not coincide as well with economic theory. We explo...

Purpose: To determine the total direct costs (fixed and variable costs) of diffusion tensor imaging (DTI) and MR tractography reconstruction of the brain. Materials and Methods: The direct fixed and variable costs of DTI with MR tractography were determined prospectively with time and motion analysis in a 1.5-Tesla MR scanner using 15 encoding directions. Seventeen patients with seizure disorde...

We extend the random coding error exponent to three common decode-and-forward schemes for the relay channel. The resulting bounds give achievable tradeoffs among rate, reliability, and delay, allowing comparison of decode-and-forward with direct transmission and other schemes in broader terms than asymptotic achievable rates alone. In contrast to the asymptotic case in which the achievable rate...

After sketching how system development and the UML (Unified Modeling Language) and the OCL (Object Constraint Language) are related, validation and verification with the tool USE (UML-based Specification Environment) is demonstrated. As a more efficient alternative for verification tasks, two approaches using SAT-based techniques are put forward: First, a direct encoding of UML and OCL with Boo...

Rule-based systems used for Optical Character Recognition (OCR) are notoriously difficult to write, maintain, and upgrade. This paper describes a method for using Genetic Programming (GP) to evolve and upgrade rules for an OCR system. The language of the evolved programs was designed such that human hand-coded rules can be included into the initial population in order to upgrade for a new font....

In this paper an object-based image ranking is performed using both supervised and unsupervised neural networks. The features are extracted based on the moment invariants, the run length, and a composite method. This paper also introduces a likeness parameter ̧ namely a similarity measure using the weights of the neural networks. The experimental results show that the performance of image retrie...

Chinese radicals are linguistic elements smaller than Chinese characters1. Normally, a radical is a semantic category and almost all characters contain radicals or are radicals themselves. In subjectivity classification on sentences, we can use radicals to represent characters, which reduce the scale of word space while keep the subjectivity information. In this paper, we manually labeled a cha...

This paper focuses the realization of a low complexity disparity estimator and the generation of arbitrary intermediate views for typical stereo videoconference sequences. The method presented has been optimized in order to achieve a very low hardware complexity keeping a good performance with regard to the addressed application. A first hardware realization of the estimator is described. Addit...
