In this paper, an intelligent controller capable of static balancing as well as dynamic balancing of a pole mounted on a motorized robot is designed and developed. The brain of the intelligent controller lies in the Fuzzy Inference System (FIS), which receives as its inputs displacement, velocity and acceleration information. An embedded instrumentation system onboard the robot measures the dis...

Middleware is increasingly used as the infrastructure for applications with stringent quality of service (QoS) requirements, including scalability. One way to improve the scalability of distributed applications is to use adaptive middleware to balance system processing load dynamically among multiple servers. Adaptive middleware load balancing can help improve overall system performance by ensu...

The emerging need for more power has led to the development of series-parallel connected battery cells. Having a more complex system also brought with it new challenges. One of these is the problem of cell imbalance. Balancing algorithms are based on extracting or adding charge in order to have balanced cells. Their goal is to protect the battery from damage and to help prolong the battery’s li...

Being inspired by the Hopfield neural networks (Hopfield (1982) and Hopfield and Tank (1985)) and the nonlinear sigmoid power control algorithm for cellular radio systems inUykan andKoivo (2004), in this paper, we present a novel discrete recurrent nonlinear systemand extend the results inUykan (2009), which are for autonomous linear systems, to nonlinear case.Theproposed systemcan be viewed as...

We discuss the general objectives and the design of base mechanisms for managing resource sharing in a heterogeneous distributed environment. Given the need for simple , safe use of the computing and communication facilities present on the network, the proposed environment should assist the user in submitting requests to the distributed system in a transparent way. The user should not need spec...

From four hours out the error in predicting wind output typically exceeds 10% MAE(perhaps 15% RMSE). Given the asymmetry in imbalance penalties from being short or long,the optimal forward contract of wind might be expected to be less than the expected output.This note derives the optimal ex ante contract position and …nds that if wind is uncorrelatedwith the system imbalanc...

The multipass-rendering method integrating radiosity with ray-tracing gives one of the best solutions for synthesizing photo-realistic images. However, the method is also computationally expensive. Therefore, parallel processing is the most promising approach to the fast multipass-rendering method. This paper presents a hierarchical parallel processing system for the multipass-rendering method....
