3.4 The Bone Marrow
The bone marrow (figure 4) produces the B-cells and hands them over to the AIS-
network. For this purpose, first antibodies are composed of arbitrarily chosen parts.
They are considered as immature and have to mature which means that the room
temperature must be adapted to the values required for the different rooms. The value
of the temperature parameter is computed from the encoding of the room and the
frequency of use and of a predefined value for each room. In addition, it is adapted by
signals from the network that record modifications of relevant antibodies in the
system. The mature antibodies are completed to B-cells by values for the three
parameters for concentration, ageing, and selection.

3.5 The Central Unit
The central unit is the interface between the AIS and the heating system as well as the
ventilation system, cf. figure 5. With respect to the heating and ventilation system, it
stores measured values from the hardware and commands from the inhabitants
concerning regulation and ventilation, and on the other side, sends commands to the
heating and the ventilation system. With respect to the AIS, it decodes the information
delivered by antibody molecules, it produces stimuli that act as a kind of interrupt
signals and are considered in this context as co-stimulative signals, and produces
antigens from the measured values and the commands. In addition, it controls the
other two components of the AIS, the network and the bone marrow.
The AIS-network is controlled by means of a number of parameters that can be
regulated by the central unit. Among them are the initial size of the population, the
size of the whole network, the number of elements that are best suited for the affinity
computation as well as those that are worst suited, the number of elements that are
best suited for mutation as well as those that are worst suited, the number of new
elements, the number of elements to be eliminated, and the mutation rate. The bone
marrow is controlled by regulation of the production of initial antibodies, the
adaptation of initial elements, the initial values of the B-cells, and other parameters.
