Real Time Emotional Control for Anti-Swing and Positioning Control of SIMO Overhead Traveling Crane

Arash Arami, Babak Hosseini

Research in artificial intelligence and bioinspired algorithms is still being actively pursued in different fields of engineering. In this work, Brain Emotional Learning Based Intelligent Controller (BELBIC) is applied for real time positioning of laborato ...

On a stochastic version of the plenacoustic function

Martin Vetterli, Andrea Ridolfi, Luciano Sbaiz, Thibaut Ajdler

In this paper, we model a spatially varying channel where a source is moving along a random trajectory with respect to a fixed re- ceiver. The aim is to compute the power spectral density corre- sponding to the channel impulse response as a function of tem ...

Robust checkers for self-calibrating designs

Frédéric Worm

So far, performance and reliability of circuits have been determined by worst-case characterisation of silicon and of environmental conditions such as noise and temperature. As nanometer technologies exacerbate process variations and reduce noise margins, ...

Analysis of Error Recovery Schemes for Networks on Chips

Giovanni De Micheli, Luca Benini, Srinivasan Murali

In this article, we discuss design constraints to characterize efficient error recovery mechanisms for the NoC design environment. We explore error control mechanisms at the data link and network layers and present the schemes' architectural details. We in ...

Iterative Correlation-Based Controller Tuning

Dominique Bonvin, Alireza Karimi, Ljubisa Miskovic

This paper gives an overview on the theoretical results of recently developed algorithms for iterative controller tuning based on the correlation approach. The basic idea is to decorrelate the output error between the achieved and designed closed-loop syst ...

Adaptive predictive power control for the uplink channel in ds-cdma cellular systems

Ali H. Sayed

In this paper, we analyze the conventional closed-loop power-control system. We explain that the system behaves essentially as a companded delta modulator and then derive an expression for the power-control error in terms of the channel fading, which sugge ...

Inverse closed-loop power control for CDMA wireless systems

Ali H. Sayed

In this work, two algorithms for closed loop power control in CDMA wireless systems are proposed. These algorithms aim to minimize the power control error by predicting the inverse of the channel fading: For this purpose, a channel fading prediction scheme ...

Dual Use of Superscalar Datapath for Transient-Fault Detection and Recovery

Babak Falsafi

Diminutive devices and high clock frequency of future microprocessor generations are causing increased concerns for transient soft failures in hardware, necessitating fault detection and recovery mechanisms even in commodity processors. In this paper, we p ...

Traffic-responsive urban network control using multivariable regulators

The paper presents the philosophy, the aim, the development, the advantages, and the potential shortcomings of the TUC (Traffic-responsive Urban Control) strategy. Based on a store-and-forward modeling approach and using well-known methods of the Automatic ...

Combining Linear Dichomotizers to Construct Nonlinear Polychotomizers

A polychotomizer which assigns the input to one of

K, K \ge 3

, is constructed using a set of dichotomizers which assign the input to one of two classes. We propose techniques to construct a set of linear dichotomizers whose combined decision forms a nonl ...
