We present how the policy enforcement point operation can be improved by applying the \"object by value\" transfer mechanisms. Policy enforcement object transferred and loaded into the policy enforcement point as a stateful object can support the adaptable behaviour of the point. We experimented with the two standard object by using the value technologies such as CORBA valuetypes and Java serialization on RMl. Examples in this paper refer to the CORBA valuetypes only.","PeriodicalId":164818,"journal":{"name":"Proceedings of the 12th IEEE Mediterranean Electrotechnical Conference (IEEE Cat.

Two of the most commonly used neural networks, the MLP (multilayer perceptron) and RBF (radial basis function) neural networks, with simple structure and standard training methods are chosen as examples. Neural network training is based on available data from a database of process variables measured over a long time period. The database in this paper is obtained using a simulation model of a real process. Without going deeper into theoretical background, relative properties of these neural networks are given through the results obtained by testing the trained networks and analysis performed on these results.","PeriodicalId":164818,"journal":{"name":"Proceedings of the 12th IEEE Mediterranean Electrotechnical Conference (IEEE Cat.

In this paper we propose an efficient and secure authenticated key agreement protocol based on Diffie-Hellman key agreement. Our protocol is more efficient than previous authenticated key agreement protocols because it requires only 1 integer multiplication. We show that our protocol meets the security attributes under the assumption that the elliptic curve discrete logarithm problem is secure.","PeriodicalId":164818,"journal":{"name":"Proceedings of the 12th IEEE Mediterranean Electrotechnical Conference (IEEE Cat.

First there were objects, and then came components and patterns, and now frameworks are becoming the current buzzword. Frameworks are powerful, but hard to develop and use effectively for application developers. It is often better to use and customize the open source frameworks than to develop in-house frameworks. Even if you are not developing the framework, but instead using an open source framework, there is still much work to be done. Deploying a framework involves a major investment in training and mentoring to allow developers to make the best use of the complex interfaces, abstract classes and classes. In this paper we discuss the open source frameworks and give an example of a database framework use in the dynamic Web applications development.","PeriodicalId":164818,"journal":{"name":"Proceedings of the 12th IEEE Mediterranean Electrotechnical Conference (IEEE Cat.

In conjunction with the highly capital-intensive feature of electricity supply, different factors can influence the profitability of the investment, such as: market rules, plant location, load demand and fuel cost trend, etc. In this paper, a methodology based on the long-term simulation of an electricity market is proposed to investigate the financial feasibility of new generation assets. The simulation tool handles zonal- or nodal- based pricing schemes, with different kinds of equality and inequality constraints. The procedure has been applied to evaluate the penetration level of combined cycle gas turbine power plants in southern Italy.","PeriodicalId":164818,"journal":{"name":"Proceedings of the 12th IEEE Mediterranean Electrotechnical Conference (IEEE Cat.

The proposed method is based on a background subtraction technique. However, instead of using a fixed background, the system relies on predicting one from a previously constructed virtual model of the environment. Thus, camera movements are allowed. These movements are estimated by means of a tracker device. We also present the virtual model construction technique for indoor environments. The method has been successfully tested for several different video sequences including capture errors, partially mapped virtual environments and camera positioning errors. Further work will focus on extending the virtual models not only to environment, but also to objects, and integrating the method in a MPEG4 standard compression system.","PeriodicalId":164818,"journal":{"name":"Proceedings of the 12th IEEE Mediterranean Electrotechnical Conference (IEEE Cat.
