The first decade of 21st century is a turning point for the Internet provision business as the end users are the customers that select the service with a given or chosen quality of service. In the case of a service provider that means to facilitate a dynamic creation of both the service and customization. This requires a new business approach in the form of a business model known as mediation. Mediation enables the smooth transition and satisfaction of the service requirement condition set up by the end user and the involved service providers. This paper provides an insight into the business layer and the relevant business model that is introduced in the IP networks that enables the QoS provision. It describes briefly the developed model and its implementation within the re-engineered provider network.","PeriodicalId":164818,"journal":{"name":"Proceedings of the 12th IEEE Mediterranean Electrotechnical Conference (IEEE Cat.

At the beginning, review of existing approaches to localization of harmonic sources is given. Then, the theoretical background of the new approach is presented. The used criterion of localization of harmonic sources in a power system is based on examining the voltage ratio, which is defined in the paper. The results of investigation of sensibility of this ratio to the errors burdening quantities used for its calculation are analyzed. The practical conclusions are given. It is underlined that the presented approach has better properties than existing ones.","PeriodicalId":164818,"journal":{"name":"Proceedings of the 12th IEEE Mediterranean Electrotechnical Conference (IEEE Cat.

To date, most narrowband radio microwave link design has relied on analog components for channel tuning and gain control. The drifts within analog components, however, necessitate frequent tuning throughout the lifetime of the equipment. This drawback can be significantly mitigated by adopting digital techniques to carry out the relevant functions. This paper presents the design of a digital software system to replace functions traditionally implemented using analog components and illustrates, through measurement results, the feasibility of the system.","PeriodicalId":164818,"journal":{"name":"Proceedings of the 12th IEEE Mediterranean Electrotechnical Conference (IEEE Cat.

In this paper we have introduced new propagation model for the streets and avenues in urban areas that can be thought as a waveguide for EM-waves. Using our developed model it is possible to calculate the contributions of each direct and scattered wave separately. We don't assume the sidewalls as perfect conducting materials in our developed model unlike the previous studies. Our simulations revealed that developed model is applicable for broadband of frequencies. If the shape of the wave-guide is entered to simulation program in great detail, the output can be very close to results that are obtained by measurements. Even the shape is not entered very accurately; an approximate result can be obtained if the fast result is needed.","PeriodicalId":164818,"journal":{"name":"Proceedings of the 12th IEEE Mediterranean Electrotechnical Conference (IEEE Cat.

To provide equal conditions actual signals from a p-i-n photodiode were simulate. A protection structure, which was applied in all read-out circuits, was characterized first. Then we measured and compared the transfer characteristics, linearity, dynamic range, detectivity and noise properties of three read-out circuits: a current-to-frequency converter, a current-to-voltage converter and a /spl Sigma/-/spl Delta/ analog-to-digital converter. The current-to-frequency converter is most appropriate for a small embedded system based on a microcontroller due to its simplicity and sufficient electronic properties.","PeriodicalId":164818,"journal":{"name":"Proceedings of the 12th IEEE Mediterranean Electrotechnical Conference (IEEE Cat.

One of the crucial issues is the implementation of the business service interface (BSI). BSI is an intermediary between the other companies and the internal business applications of a company that is engaged in electronic business. BSI is not directly specified. Its behavior and its assignments are specified indirectly through the other specifications. This paper discusses and describes a general structure of BSI so it would comply with all the requirements which are also discussed. BSI would enable the companies to engage in electronic business collaborations according to the previously specified business processes that are agreed with the other party. It would enable conducting the business with a minimum human interference. BSI would also enable the human control of delicate business transactions.","PeriodicalId":164818,"journal":{"name":"Proceedings of the 12th IEEE Mediterranean Electrotechnical Conference (IEEE Cat.
