This work describes a method that makes the Java instruction as small as possible. The proposed method, called "nibble coding", compresses two instructions into one byte. The experiment is carried out to compare Java byte code instruction and a modified code with the nibble coding. The result shows the proposed scheme achieves a much smaller instruction bandwidth than the ordinary byte-code cou...

In this paper, the fuzzy system has been used for fault detection and diagnosis of a yeast fermentation bioreactor based on measurements corrupted by noise. In one case, parameters of membership functions are selected in a conventional manner. In another case, using certainty factors between normal and faulty conditions the optimal values of these parameters have been obtained through the g...

This paper presented a novel decentralized fault tolerant control strategy for the control of linear multivariable processes. The multiple model based fault tolerant method is used to improve system performance (under model uncertainty and slow variation) and implement active fault tolerant control. In the mean time, we extended the decentralized unconditional stable control to multiple model c...

In certain memory systems the most common error is a single error and the next most is double error type. Here we propose a methodology and implementation of CA (cellular automata) based error correcting codes (ECCs) those are widely applied in computer memory systems. These increase reliability and data integrity. In this paper, we have proposed a novel approach for designing four byte error d...

Past few years have seen an extensive use of RAM chips with wide I/O data (e.g. 16, 32, 64 bits) in computer memory systems. These chips are highly vulnerable to a special type of byte error, called an m-spotty byte error, which can be effectively detected or corrected using byte errorcontrol codes. The MacWilliams identity provides the relationship between the weight distribution of a code and...

This work is concerned with multiple faults isolation for hybrid systems based on Global Analytical Redundancy Relationships (GARRs) approach. GARRs are derived from the Hybrid Bond Graph (HBG) model of a hybrid system with a specified causality assignment procedure. In this article, multiple faults are considered in a complex hybrid system and these faults can develop during a mode when the fa...
