Several industrial systems are required to carry out a sequence of missions in which the maintenance activity is allowed only between two consecutive missions. In such case, the selective maintenance strategy is widely adopted, which aims to select the best components to be maintained, taking into account the constrained maintenance resources. The suggested maintenance selective resolution methods...
In recent years, ontologies as a semantic knowledge representation become widely used in many information systems. Manual creation of ontologies by domain experts and ontology developers is also a costly task, time consuming and needs extra efforts. Learning Non-Taxonomic Relationships is a subfield of ontology learning which targets automatic extraction of non-taxonomic relationships from input,...
The excessive use of the communication networks, rising of Internet of Things leads to increases the vulnerability to the important and secret information. advance attacking techniques and number of attackers are increasing radically. Intrusion is one of the main threats to the internet. Hence security issues had been big problem, so that various techniques and approaches have been presented to address...
In this paper, we present a novel hardware implementation of a watermarking system applied on the digital image. The proposed hardware system is based on the DWT (Haar discrete wavelet transform) on the first level of the decomposition. The watermark is hidden in the LH0 (mean frequency sub-band) in goal to get a maximum of the compromise between the visibility and the robustness factors against several...
Offline optimization of controller parameters for complex non-linear processes can be time consuming, even with high performance computers. This project demonstrates how Metamodeling techniques can be utilized to tune the controller parameters for a non-linear process quickly. The process used in this study is the mixing process which is a multivariable and intrinsically non-linear plant. The Radial...
