This paper describes the design and implementation of the fuzzy control system for a small, reactive mobile robot which operates in an unknown , unpredictable, and dynamic environment. A modular, two-level fuzzy controller is used for navigation, obstacle avoidance, and target tracking. The fuzzy controller provides the mechanism for fusing noisy sensor data from multiple sensors which may pres...

|An issue central to the navigation problem is memory. Traditional systems build symbolic maps of the world for navigational reference. Reactive methods, in contrast, eliminate or minimize the use of memory. These reac-tive techniques have been remarkably successful at solving a wide range of navigational problems. Some problems, however, still present a challenge to reactive strategies, (box c...

Reactive aggression (RA) is an angry response to perceived provocation. Proactive aggression (PA) is a pre-meditated act used to achieve some goal. This study test hypotheses that (1) individuals high in RA and PA will differ in resting levels of autonomic arousal and (2) RA will be related to emotional and behavioral problems, while PA only to behavioral problems. Parents of 68 children (age 6...

We employ reactive dynamical density functional theory and Brownian dynamics simulations to study the non-equilibrium structure phase behavior of active soft colloids in which each particle switches stochastically between two states.

Reactive rules are used for programming rule-based, reactive systems, which have the ability to detect events and respond to them automatically in a timely manner. Such systems are needed on the Web for bridging the gap between the existing, passive Web, where data sources can only be accessed to obtain information, and the dynamic Web, where data sources are enriched with reactive behavior. Th...

Abstract Environmental sustainability is described as one that avoids the depletion or deterioration of natural resources, while also allowing for preservation long-term environmental quality. By practicing sustainability, we may assist to guarantee requirements today’s population are satisfied without risking capacity future generations meet their own needs in future. Engineers field concrete ...

This work presents a fast and direct controlled routine for the fabrication of fully dense alumina based on reactive spark plasma sintering (reactive-SPS) boehmite (γ-AlOOH) nano-powders obtained by sol–gel technique. The evolution transition aluminas during has been studied. Some powders were seeded with α-Al2O3 particles prior to gelation. Boehmite exhibited at 1070 °C, enhancing transformati...
