The transmission of information relying on the perturbation of nonlinear oscillators vector fields can be approached in a unified manner. This can be accomplished by making use of the Information Transmission Via Control principle, which is stated and proved in the present work. In short, this principle establishes that any controller used to identically synchronize pairs of nonlinear oscillato...

Objective. To explore midwives’ perceptions of developing their practice knowledge and skills, concerning maternal postnatal genital tract assessment (GTA); and to highlight how midwives pass on their practice knowledge and skills to student midwives. Design. A constructionist grounded theory methodology was employed to guide the design and processes. Ethical approval was gained from the region...

Alon, N., Transmitting in the n-dimensional cube, Discrete Applied Mathematics 37/38 (1992) 9-1 I. Motivated by a certain communication problem we show that for any integer n and for any sequence (a,,...,ak) of k = [n/21 binary vectors of length n, there is a binary vector z of length n whose Hamming distance from a, is strictly bigger than k-i for all 1 5 i 5 k. The n-dimensional cube is the g...

Information-theoretic secrecy is combined with cryptographic secrecy to create a secret-key exchange protocol for wireless networks. A network of transmitters, which already have cryptographically secured channels between them, cooperate to exchange a secret key with a new receiver at a random location, in the presence of passive eavesdroppers at unknown locations. Two spatial point processes, ...

The current state of the RFC 3550 RTP/RTCP standard is not optimal for large-scale streaming sessions employing sourcespecific multicast and is currently the subject of research in many research laboratories. The most promising optimization for the RTP/RTCP protocol seems to be hierarchical aggregation [2], [3], [5], [6], [10], [11]. However, hierarchical aggregation has not yet completely solv...
