Using the Thomas-Fermi model, we investigated the electric characteristics of a static non-magnetized strange star without crust in this paper. The exact solutions of electron number density and electric field above the quark surface are obtained. These results are useful if we are concerned about physical processes near the quark matter surfaces of strange stars. PACS: 97.60.Gb, 97.60.Jd, 97.6...

In this study, we evolve both the controller and morphology of artificially embodied legged creatures. This is achieved by relaxing certain morphological constraints previously imposed on the artificial creature where the focus had only been on the optimization of its artificial neural network (ANN) controller. The first objective is to explore the legged locomotion behaviors that can be achiev...

An investigation of the distributional characteristics of 440 large-sample achievement and psychometric measures found all to be significantly nonnormal at the alpha .01 significance level. Several classes of contamination were found, including tail weights from the uniform to the double exponential, exponential-level asymmetry, severe digit preferences, multimodalities, and modes external to t...

This work introduces a numerical, continuous measure of symmetry for 3D stick creatures and solid 3D objects. Background information about the property of symmetry is provided, and motivations for developing a symmetry measure are described. Three approaches are mentioned, and two of them are presented in detail using formal mathematical language. The best approach is used to sort a set of crea...

By comparing the magical creatures within Harry Potter to the nineteenth-century freak show, the mistreatment and lack of concern for the basic rights of centaurs, giants, and house-elves are put into perspective due to the now-uneasy feeling many acquire when thinking of the exhibition of people as “freaks.” Digital Literature Review, vol. 3 (2016). © Ball State University.

A pedagogical overview of strange quark matter and strange stars is presented. After a historical notation of the research and an introduction to quark matter, a major part is devoted to the physics and astrophysics of strange stars, with attention being paid to the possible ways by which neutron stars and strange stars can be distinguished in astrophysics. Recent possible evidence for bare str...

We present a system that can evolve the morphology and the controller of virtual walking and block-throwing creatures (catapults) using a genetic algorithm. The system is based on Sims' work, implemented as a flexible platform with an off-the-shelf dynamics engine. Experiments aimed at evolving Sims-type walkers resulted in the emergence of various realistic gaits while using fairly simple obje...
