Signal transformation

One of the characteristics of basic devices is that they cannot be split up into parts. A basic device can also be a signal transformer (a function tvhich transforms the input into output, such as the thermocouple that transforms the input temperature into an electrical tension). The process phases are connected and characterized quantitatively, from the vievrpoint of characteristic relations (equations), as in Fig. 1.4 [1.11-1.13]. This structured mathematical modelling development corre-... 

Various laws restrict the values of the process quantities. These laws may represent either fundamental, empirical physicochemical relationships or experimentally identified equations (from statistical modelling or from dimensional analysis particularizations). In contrast to statistical or dimensional analysis based models [1.14], which are used to fix the behaviour of signal transformers, the models of transport phenomena are used to represent generalized phases and elementary phase connections. Here, the model equations reveal all the characterizing attributes given in the description of a structure. They include balance equations, constitutive equations and constraints.

The one-to-one correspondence between the NMR signals and the carbon atoms and the assignment of possibility values through the membership function to each signal transforms the crisp set of vertices V from definition (3) of the graph into a fuzzy set forming a fuzzy molecular graph. 

The means of signal transformation (appropriate physical conversion processes). 

Add the incoming signals of each neuron, multiplied by the weights ofthe corresponding links and take the product as an input for the neuron s signal transformation function. Take the output as an input for all the connected neurons in the subsequent layer do the same... until the output neurons are reached.

A sensor is typically a device that transforms signals from the mechanical, thermal, radiant, chemical, or magnetic domain to the electrical domain. A single sensor may be based on crosseffects between different signal domains to achieve the signal transformation to the electrical domain to be read by a human or an electronic instrument. These cross-effects are shown in Table 1, where the input signal domains are on the left-hand side, and the output signal domains are at the top (Meijer 2008). 

Passive systems and safety devices of special design not requiring any intervention for a start-up, or those actuated without power consumption, by signals of changing physical parameters of the medium (without signal transformation).
