The progress of mathematical modeling and image processing in medicine from the last decades have had an important impact in the development of diagnosis and treatment of cardiovascular diseases using the simulations of blood flow and pressure evolution models in specific location of the heart or vessels, personalised with patient data. This method is expected to increase the efficiency and reduce the recovery time of the patient. In this paper, it is depicted the cardiovascular system and his pathology, the non-invasive technologies of investigation, as well as the multiscale models that couples the elements of the cardiovascular system. Finally, the results of a simulation with a variable elastance model of the heart initialized with patient data coupled with a Windkessel model for the coronary circulation with mean values from the literature.

Smart Grid's vision is about a bold program of research, development and demonstration that charts a course towards an electricity supply network that meets the needs of Europe's future. The Smart Grid will include automation software and intelligent electronic hardware systems that control the transmission and distribution power grids. For developing distribution management and functionality of electricity market one essential objective is to make the customer active for efficient use of energy. The evolution from grid to Smart Grid is based on different functions and on the complexity of the nodes starting from interconnection between local control and central control and arriving to the Smart Grid control hub with a great level of independence and a complex functionality. The Smart Grid of the future will act much more like an interactive web, or “energy Internet,” with two-way communication, multi-directional power flow, distributed intelligence including close-loop control, stability and balance performed on site and optimization at its core. The paper presents the authors view about Smart Grid state of the art and point out the stage in standardization and practice. The contribution is on defining the functions performed by each development stage of equipment: bridge, gateway, node and control hub, the control hub architecture and the demonstrator for the gateway and protocol converter.

This paper proposes a modern approach for the methodology that supports the measure the audience for outdoor poster advertising. The classic approach of conducting complex, limited and expensive studies about human daily routes, related just to a limited type of advertising poster may be enriched using the data that resides in the monitoring infrastructure of the cellular telecom operators over digital maps. Well segmented, this kind of data may reveal important features of the population activity at a large scale. Finally, the fine tuning options in analyzing this kind of data are discussed for future improvements.

The modeling, identification and control of distributed parameters systems, represent one of the important directions of theoretical and practical research, due to the large class of applications in which they can be involved[3-14, 33-37]. This paper proposes, an identification solution for a system with distributed parameters, represented by a heat exchanger with encasing, using open-loop identification techniques, based on whitening of the prediction error: Recursive Least Square(RLS), Extended Least Square (ELS), Recursive Maximum Likelihood (RML) and Generalized Least Square (GLS)[1,15,16,17,18]. By the discretization of the analytical model of the plant, the open-loop identification techniques, are tested for all the possible amplification gains and an optimal model with minimal order is chosen in order to chose a simple control solution.

For the attractor determination, we propose in this paper a new approach based on the definition of a comparison system by special description of the linearized model of the process around an operating state which correspond to a diagonalization or if it is not possible to the description with a matrix on the arrow form, and the use of aggregation techniques. As an illustration, this approach is applied with success for the case of a third order non linear system.

Intrusions detections systems from point of view of security policy are a second line of defense; they have a supervisory role to observe the activities of our network or hosts to identify attacks in real time. In our days, electronics attacks can cause a very destructive damage for nations which make necessary the use of completed security policy to minimize the potential threats. IDS it is a very important element to resist against this vulnerability, in our works, we use a wired data base Knowledge Discovery Data Mining (KDD) CUP 99 and a Data Mining Tools Waikato Environment for Knowledge Analysis (WEKA) to combine the advantages of an intrusion detection algorithm (PART) and two techniques of Dimensionality Reduction(best first search and genetic search), to evaluate our works, we applied the proposed combined technique, and we check the results by using a several evaluations parameters. The results show that a very high detection rate for certain attacks types and highest sensitivities with the hybrid dimensionality reduction method.

The objective of this paper is to design a real-time control solution for chemical processes, namely the ethylene reactor, the key-installation in the petrochemical industry. The controller used is lag or lead controller, a simple yet suitable control tool. This article deals with the problem of finding all first order controllers that stabilize a given LTI continuous time or discrete time plant and attain various performance specifications. The main tool for the controller design is Neimarks D-decomposition, which was originally introduced in 1949 in the Russian control literature. The process data have been measured from an assembly of pyrolysis reactors on the petrochemical platform from Pitesti, Romania.

Starting from some recently analyzed controlled models with propagation i.e. described by hyperbolic partial differential equations, it is shown that a Liapunov functional may be attached in a natural way by using development of the energy integral. As known from the general theory of the hyperbolic partial differential equations, the energy integral is a useful tool for obtaining uniqueness theorems. On the other hand, existence theorems may be obtained either starting from difference schemes (the approach of S.K. Godunov) but also by associating some functional differential equations (the approach of A.D. Myshkis, K.L. Cooke and their followers). Due to the one to one correspondence between the two mathematical objects, the counterpart of the Liapunov functional deduced from the energy integral is obtained for the functional differential equations. Using these mathematical tools some process applications are discussed: flexible beam (manipulator), flexible overhead crane and to applications of controlling the oil drilling plants. The outcome of the analysis is given by control structures and stability criteria.

A container terminal is a complex set of logistics systems with dynamic and random interactions. Information related to the container flow is often uncertain. This modification is due to inaccuracies in the arrival, departure dates of ships and arrival times of customers' trucks. Indeed, the container storage problem becomes a dynamic problem which was the subject of this work. In this paper, a heuristic method for re-marhaling outbound and inbound containers is presented. With this method, we can overcome the uncertainties of departure, arrival time of container and improve the container storage planning. This problem is studied with different container types (regular, open side, open top, tank, empty, refrigerated). The objective is to find an optimal container storage plan which respects the departure dates of container and minimize their re-handling operations at their departure time. Some experimental results are presented and discussed to verify the performance of the proposed approach.
