This paper addresses the problem of robust filtering for uncertain linear signal models affected by time delays in the state. Uncertainty is structured and the model is assumed to lie in a given bounded polyhedral set. The main innovation is the use of a nonrational filter, that is, a filter that also contains delays in the filter state. Robust filtering performance is evaluated using the H2 or the H∞ norm. The performance conditions are delay independent, and provide convex filtering design problems which are convex optimization problems with linear matrix inequalities constraints.
Using dimensional analysis and numerical optimisation techniques, an optimal method for tuning PID controllers for first order plus time delay systems is presented. Considering integral square error (ISE), integral ab...

Document analysis and understanding (DAU) systems aim not only at the recognition of text but also at the extraction of relevant information out of a scanned document. Numerous studies have introduced efficient algorithms for document analysis, some of these studies proposed an articulated and/or a translation stage. Also little work has been done in the English/Arabic (E/A) translation area. The main objective of this paper is to introduce a combination between the three trends (document understanding, E/A translation, and handling the output in articulated voice). This paper focuses on the realization of a bilingual articulated E/A system based on optical character recognition (OCR). The input of the proposed system will be an English or Arabic text through scanner or video camera;the output will be an articulated voice. The proposed scheme consists of two phases. The first phase consists of many processes, beginning with converting scanned document into an electronic processable form. Then in the segmentation step, the essential problem in Arabic OCR, that is, how to cope with the various shapes of the same character, is solved. A new methodology for segmenting Arabic characters is presented. At the end of this phase an efficient method of text recognition based on hybrid description (ANN, FFT) is used. In order to verify the performance of this phase, experiments with printed text were performed. The error rates were less than 0.1%. Results showed that the proposed scheme in this phase is very robust. In the second phase, a database with 3000 audio files was encapsulated to convert each word from the input text (the output of the first phase) to its correspondence. This research can help in many real-time applications such as: (immediate translation, machine reader for blind people, learning...).

The object-oriented design methodology has been manipulated to model the standard CMOS fabrication technology. Detecting and characterizing the objects and classes within the basic object-oriented features of encapsulation, inheritance and polymorphism, as well as discussing the model framework and model characterization has been the main pursuits of this works. This modeling approach puts forth the chance of a fully automated fabrication system, with well-characterized hardware and reusable software. This model is also a promising candidate for enhancing the system performance to the minimum level required for fully integrated agent-oriented entities, which can reconfigure themselves for future technology generations.
