Message complexity

In the case of interactive authentication, as with all interactive protocols, an important criterion is the round complexity, i.e., the number of rounds needed. Message complexity, the number of separate messages sent during a protocol execution, essentially equals round complexity in 2-party protocols, but bit complexity, the number of bits sent, is as important as usual. The bit complexity of non-interactive authentication is the length of the signature. 

The key message is that aspects of symbolic representation that are familiar and taken for granted by experts (i.e. chemists, science teachers etc.) may not always be well understood by students. This has been found even at university level (Marais Jordaan, 2000). A primary aim of this chapter is to make explicit some of this complexity and abstraction, to remind experts how apparently straightforward aspects of our symbolic representations can actually present a significant demand on learners who lack ... 

Coupled classifiers can perform complex calculations, such as handling temporal information. Recall that the input message list delivers a snapshot of current conditions in the reactor. If the reactor contains a pH probe, the message that the probe sends will define the latest pH of the reaction mixture. 

Going from top to bottom the systems add on to the previous systems so complexity increases, and message media and carriers were extended. The available chemicals also change from top to bottom systematically. Time from initiation to action. 

For a complex multicellular organism to function, cells must rapidly respond to messages from other regions of the organism. These messages, often in the form of hormones, arrive at the cell membrane through the aqueous environ-...
