Controversy exists as to whether semantic disruption in Alzheimer's disease (AD) systematically impairs the naming of living things. Moreover, little is known about performance across more specific subcategories. We investigated picture naming in 28 AD patients and 24 controls. To deal with nonnormal distributions, we created 1,000 bootstrap hierarchical regressions and determined which variabl...

based on dynamic modeling, robust trajectory tracking control of attitude and position of a spherical mobile robot is proposed. in this paper, the spherical robot is composed of a spherical shell and three independent rotors which act as the inner driver mechanism. owing to rolling without slipping assumption, the robot is subjected to two nonholonomic constraints. the state space representatio...

In recent years, soft computing methods, like fuzzy logic and neural networks have been  presented and developed for the purpose of mobile robot trajectory tracking. In this paper we will present a fuzzy approach to the problem of mobile robot path tracking for the CEDRA rescue robot with a complicated kinematical model. After designing the fuzzy tracking controller, the membership functions an...

Sound symbolism is the non-arbitrary use of speech sounds to convey meaning. For example, we tend to mark large objects with back vowels, e.g., /u/ in ”huge,” and small objects with front vowels, e.g., /i/ in ”tiny.” Previous research into sound symbolic naming has suggested that an object’s motion is considered when naming the object. We report results from two experiments in which participant...

Five chronometric experiments examined the functional architecture of naming dice, digits, and number words. Speakers named pictured dice, Arabic digits, or written number words, while simultaneously trying to ignore congruent or incongruent dice, digit, or number word distractors presented at various stimulus onset asynchronies (SOAs). Stroop-like interference and facilitation effects were obt...

The Tilde naming system identifres files in a distributed computing system in a novel way, providing a consistent mechanism for referencing both local and remote files that is independent of the details of the underlying computing environment. The Tilde naming system achieves this independence by providing each user with control of a private name evaluation environment. In contrast, several con...
