An infrared alcohol testing system based on differential absorption is presented. The technique relies on the fact that the breath alcohol gas has a unique, well-defined absorption characteristic within the infrared region of electromagnetic spectrum. It is used to detect the present and concentration of alcohol gas. The non-dispersive infrared gas detection principle is introduced in detail. Experiments show that the testing system has high precision, good environment adaptability, and its indication error and repeatability reach the China National Standards.

This paper investigates signal and system representations in special rational orthogonal bases of the Hardy space H 2 . These bases are derived from the Blaschke-group associated to the hyperbolic group SH(n) of matrices. Using the concept of the unitary group representations over H 2 , and the voice-transform, specific hyperbolic wavelet constructions - Blaschke-wavelets and the associated Blaschke-Fourier transform are constructed. State space representations of systems over hyperbolic groups are discussed, too, with the purpose to explore the perspectives of elaborating a unified system theory upon this conceptual base.

In societal system disputes and in direct conflict of interests, in particular, the decision making faces a basic situation resembles a combat-like situation (Figure 1). For each of the opponents (‘players’) has in mind and carries out own missions in the societal environment (Figure 2) Furthermore, two or more parties need to make decisions with fully or partially conflicting objectives when involved in a dispute or open conflict. And yet, by and large, decisions must be made under risk, uncertainty, and incomplete or fuzzy information based on adaptive perception knowledge (Figure 3), which may imply large amounts of linguistic and probabilistic information with missing data. In the case of two opponents, the synergy of fuzzy approach and matrix games seems rather effective for modelling such multi-criteria conflicting situations. This synergy is feasible provide the game equilibrium stability concept is conceived in compliance with an adequate uncertainty preference scheme of decision making. In the case of two scenarios or states of a conflict, the preference scheme for a given participating decision-maker has to include components for handling cases of one state strict preference over another state, equal preference between the states, and also uncertainty preference. The fuzzy modelling based procedure is employed to take into account some of the subjective attitudes of the decision makers that are difficult to model using classical game theory.

In societal applications of systems science where competition under conflicting interests is pertinent to, the decision making faces situations in which one must decide whether to cooperate or not with a competitor or opponent. Each of the opponents (‘players’) has as well as carries own missions within the society out. At least two if not more parties need to make decisions under fully or partially conflicting objectives when involved in a dispute or open conflict. By and large decisions must be made under risk, uncertainty, and incomplete or fuzzy information implying large amounts of linguistic and probabilistic information. For cases of two opponents, the synergy of fuzzy control approach and matrix games seems rather effective to represent and find solutions for such multi-criteria conflicting situations. The fuzzy procedure is used to take into account some of the subjective attitudes of the decision makers that are difficult to model using classical game theory.

Segmentation of abdominal aortic aneurysms in CT images using a radial model approach

Abdominal Aortic Aneurysm (AAA) is a dangerous condition where the weakening of the aortic wall leads to its deformation and the generation of a thrombus. To prevent a possible rupture of the aortic wall, AAAs can be treated non-invasively by means of the Endovascular Aneurysm Repair technique (EVAR), which consists of placing a stent-graft inside the aorta in order to exclude the bulge from the blood circulation and usually leads to its contraction. Nevertheless, the bulge may continue to grow without any apparent leak. In order to effectively assess the changes experienced after surgery, it is necessary to segment the aneurysm, which is a very time-consuming task. Here we describe the initial results of a novel model-based approach for the semi-automatic segmentation of both the lumen and the thrombus of AAAs, using radial functions constrained by a priori knowledge and spatial coherency. © 2009 Springer Berlin Heidelberg.

The robust H_(infinity) control problem for the generator excitation system with the damping coefficient uncertainty and external disturbances, is addressed. Storage functions of the control system are constructed based on modified adaptive backstepping sliding mode control method and Lyapunov method. A nonlinear robust H_(infinity) controller and a parameter updating law are obtained simultaneously. The controller can not only attenuate the influences of external disturbances on the system output, but also has strong robustness for system parameters variation. Since the controller design is based completely on the nonlinear dynamic system without any linearization, the nonlinear property of the dynamic system is well preserved. The simulation results show that more rapid speed response and stronger robustness can be obtained by the proposed method than the conventional adaptive backstepping and adaptive backstepping sliding mode control methods.

Ontology-based design pattern recognition

12th International Conference on Knowledge-Based Intelligent Information and engineering Systems

This paper presents ontlology-based architecture for pattern recognition in the context of static source code analysis. The proposed system has three subsystems: parser, OWL ontologies and analyser. The parser subsystem translates the input coded to AST that is constructed as an XML tree. The OWL ontologies define code patterns and general programming concepts. The analyser subsystem constructs instances of the input code as ontology individuals and asks the reasoner to classify them. The experience gained in the implementation of the proposed system and some practical issues are discussed. The recognition system successfully integrates the knowledge representation field and static code analysis. resulting in greater flexibility of the recognition system.

作者： Enescu, Nicolae-Iulian Mancas, Dan Manole, Ecaterina-Irina Computer and Communication Engineering Department Faculty of Automation Computers and Electronics Bvd. Decebal Nr. 107 200440 Craiova Dolj Romania

The purpose of our research is to find algorithms for loading large maps on PDA and place on it the geographical location given by latitude and longitude. C++ and C# programming languages have been used for implementation. It was elaborated a software which runs on PDA with Windows Mobile 2003 OS and implements algorithms for finding the coordinate on a map represented like a TIF image. The application must localize the coordinates known by longitude and latitude over a given image in TIF format which can represent a map with scale 1:200000 or 1:25000. The map headers contain information that refers to map limit. An algorithm that permits map synchronization when the value of current map is out of limit it was necessary.

The scope of our research is finding a correlation between the correctness indicator and the reliability indicator for software programs. For this, the correctness and reliability indicators will be calculated for a simple program, written in C programming language. The computations will be made for each program version obtained by correcting different error type found in the testing process. Will be observed there is a closed correlation between correctness and reliability in the way that for an increasing of the correctness level there will also be a significant increase of the reliability level.
