Supervision registers

Registers

Consider a system of asynchronous processes that communicate among themselves by only executing read and write operations on a set of shared variables (also known as shared registers). The system has no global clock or other synchronization primitives. Every shared variable is associated with a process (called owner) which writes it and the other processes may read it. An execution of a write (...

Supervision of Supervision

At the very beginning of working with the group as a supervisor – the dynamics of which I will analyse more thoroughly in the section Personal Experience, group members were discussing their personal experience of the supervisee’s position, their past, present and anticipated relationship with the supervisor and their experience of the supervision of the supervisor. Although they broached many ...

Shift Registers

A homomorphism of the de Bruijn graph that maps a graph of order n onto one of order n -1 and its applications to the design of nonsingular feedback shift registers are discussed. The properties preserved under this mapping suggest a new design technique whose main advantage is due to the fact that the problem of designing a desired n-stage shift register may be reduced to a problem of order n ...

Algebraic Feedback Shift Registers

A general framework for the design of feedback registers based on algebra over complete rings is described. These registers generalize linear feedback shift registers and feedback with carry shift registers. Basic properties of the output sequences are studied: relations to the algebra of the underlying ring; synthesis of the register from the sequence (which has implications for cryptanalysis)...
