The paper presents an efficient computation sensitivity method for the analog two-port linear networks, without using the circuit topology. It is consider the steady state non-sinusoidal regime and the algorithm analyze the sensitivities of the network functions correlating it to the relative values which characterize the input current and voltage harmonics. Numerical examples are used for the discussion of some aspects related to the sensitivity groups' problems.

The importance of the heating systems is given both by the quality brought to the social life and from the point of view of pollution. Environmental pollution, global energy crisis as well as global energy policy and our gas heating systems. This motivating reason for the heating system, in terms of their viability and pollution reductions, is the future. In this article a dual heating system is presented, while an electric heating system and one of the gases, the care is coordinated by a monitoring and control system. The operating strategy of the two systems is dictated by an algorithm and a cost optimization function. The use of a dual heating system is the result of comparative results regarding the measurement of the measures and the simulation of the algorithm.
