This paper covers the modeling and nonlinear attitude control of the Cubli, a cube with three reaction wheels mounted on orthogonal faces that becomes a reaction wheel based 3D inverted pendulum when positioned in one of its vertices.The proposed approach utilizes quaternions instead of Euler angles as feedback control states.A nice advantage of qu
Crushing of rock particles is a phenomenon commonly encountered in geotechnical engineering practice.It is however difficult to study the crushing of rock particles using classical theory because the physical structure of the particles is complex and irregular.This paper aims at evaluating fractal and morphological characteristics of single rock pa
Attentional processes play a complex and multifaceted role in the integration of input from different sensory modalities.However, whether increased attentional load disrupts the audiovisual (AV) integration of common objects that involve semantic content remains unclear.Furthermore, knowledge regarding how semantic congruency interacts with attenti
A speech-action-repository (SAR) or mental syllabary has been proposed as a central module for sensorimotor processing of syllables.In this approach, syllables occurring frequently within language are assumed to be stored as holistic sensorimotor patterns, while non-frequent syllables need to be assembled from sub-syllabic units.Thus, frequent syll
Dear Editor, Education is a complex issue and there is a need to consider a several factors to provide an effective training program.Regarding the issue of road traffic crashes, there are some contradictory findings about the efficacy of education, which may cause mistrust among professional circles and experts.Some scientists believe that most of
