Obstacle avoidance in a solar powered autonomous vehicle

Abstract: In this paper design and testing of a solar powered autonomous vehicle which navigates in the presence of obstacles is presented. Obstacle avoidance is the most crucial task of an autonomous system. Hence any autonomous vehicle should have the capability to perform sudden maneuvers when an obstacle is detected. The vehicle has a sensor which estimates the distance at which the obstacle is present and the obstacle's height and width. A microcontroller controls the entire system which consists of dual batteries, four wheels, sonar sensor whose movement is controlled by two servo motors and solar panels which are a source of power supply. One of the batteries is connected to the load and the other to the solar panel. Charging and discharging happens simultaneously unlike conventional designs where the power source is used to recharge a single battery. The sensor data collected by the controller is used to maneuver the vehicle. The vehicle developed can explore any alien environment and take decisions autonomously.

A Three-Dimensional Chaotic System with Square Equilibrium and No-Equilibrium

Abstract: Recently, Leonov and Kuznetsov have introduced a new definition “hidden attractor”. Systems with hidden attractors, especially chaotic systems, have attracted significant attention. Some examples of such systems are systems with a line equilibrium, systems without equilibrium or systems with stable equilibria etc. In some interesting new research, systems in which equilibrium points are located on different special curves are reported. This chapter introduces a three-dimensional autonomous system with a square-shaped equilibrium and without equilibrium points. Therefore, such system belongs to a class of systems with hidden attractors. The fundamental dynamics properties of such system are studied through phase portraits, Poincare map, bifurcation diagram, and Lyapunov exponents. Anti-synchronization scheme for our systems is proposed and confirmed by the Lyapunov stability. Moreover, an electronic circuit is implemented to show the feasibility of the mathematical model. Finally, we introduce the fractional order form of such system.

Mobile Agent System for Computer Network Management

Abstract: Conventionally, the management of computer networks involves the physical movement of the Network Administrator from one computer location to another. The mathematical modeling and simulation of mobile agent systems for the management of the performance of computer networks with emphasis on quantitative decision variables have been reported in the literature. The prototype of an expert system for the administration of computer networks resources with emphasis on both quantitative and qualitative decision variables using mobile agent technology is presented in this paper. The architecture of the system is characterized by the relational database of the computer networks resources and the process of management is modeled by using Unified Modeling Language (UML) and Z-Notation. The implementation of the mobile agent is driven by intelligent mechanism for de-assembling, serializing, queuing, and Divide-and-Conquer Novelty Relay Strategy of its component parts (subagents), and a mechanism for assembling the output reports of the subagents. The ultimate goal is to provide an intelligent autonomous system that can police the economic use of the computer network resources and generate desirable statistics for policy formulation and decision making.

The Survival Analysis of a Non-autonomous N-dimensional Volterra Mutualistic System in a Polluted Environment

Abstract: In this paper, we extend the autonomous n-Dimensional Volterra Mutualistic System to a nonautonomous system. The condition of persistence and extinction is obtained for each population, and the threshold is established for asymptotically autonomous system.
