In this paper we are concerned with the reliability, i.e., probability of success, of reactive system components (behaviors) in autonomous systems such as mobile robots. A method is presented for designing reliable behaviors by a suitable integration of a set of less reliable ones, which can be based on diierent and complementary algorithms , sensors etc. The presented approach is based on the ...

Armature Reaction: The effect of magnetic field set up by armature current on the distribution of flux under main poles of a generator. The armature magnetic field has two effects: (i) It demagnetises or weakens the main flux and (ii) It cross-magnetises or distorts it. Fig 1 shows the flux distribution of a bipolar generator when there is no current in the armature conductors. The brushes are ...

Generally speaking the greater the number of Mycobacteria lepra: there in the system, the greater is the tendency to leprous reaction. Reaction is rarely seen in the early case of nerve leprosy, but the passage from the A1 stage to the B1 stage may be marked by leprous reaction. During the B stages of skin leprosy, reaction is much more commonly seen, but as the A2 stage is approached, reaction...
