Despite their basic attractiveness as an interaction paradigm for controlling intelligent environments, the design of spoken dialog systems for this purpose raises some usability challenges that require careful attention. This paper examines closely the communication failures that can occur in the control of one particular type of intelligent environment: a smart home system that provides contr...

The most common controller in wind turbine is the blade pitch angle control in order to get the desired power. Controlling the pitch angle in wind turbines has a direct impact on the dynamic performance of the machine and fluct­uat­io­ns in the power systems. Due to constant changes in wind speed, the wind turbines are of nonlinear and multivariate system. The design of a controller that can ad...

The authors present a precedence based bandwidth management and pricing proxy server for controlling Internet communication in an intelligent and adaptive manner. Both proportional fairness and congestion avoidance flow control treatments are examined. The proposed proxy server is designed to alleviate Internet congestion and apply priority and incentive based Internet usage and pricing.

In this paper we address the problem of realizing a service-providing reasoning infrastructure for proactive human assistance in intelligent environments. We propose SAM, an architecture which leverages temporal knowledge represented as relations in Allen’s interval algebra and constraint-based temporal planning techniques. SAM seamlessly combines two key capabilities for contextualized service...

Oil reeneries literally provide the lifeblood for global economic health, and disruptions to their operations have major worldwide impact. We are developing a large-scale intelligent reenery control system to assist human operators in controlling reeneries during abnormal situations. Based primarily on reactive and procedural approaches to intelligent behavior, the Abnormal Event Guidance and I...

A proportional integral derivative (PID) controller is the most commonly used controller in controlling industrial loops due to its simple structure, robust nature and easy implementation. Tuning a PID controller is an important task. The conventional methods for tuning a PID controller have certain limitations. These limitations can be taken care by tuning the PID controller using intelligent ...

An agent oriented management framework for pricing and controlling multimedia communications is presented as an on going research project. The framework model is described in terms of agent roles identified in multimedia domains. The agent components developed are based on CORBA technology allowing for object transparency. The use of intelligent, mobile and automated software provides a powerfu...

Abstract—In this paper, an intelligent backstepping controller, tuned using a chaotic particle swarm optimization (CPSO), is proposed to control of chaos in Genesio-Tesi chaotic system. Thebackstepping method consists of parameters with positive values. The parameters are usually chosen optional by trial and error method. The improper selection of the parameters leads to inappropriate responses...
