This paper presents a novel gait generation approach which combines a reactionary and a central pattern generator (CPG) system. The former couples isolated leg controllers by simple gait generation rules that ensure static stability and produce a continuum of gait patterns across the full speed range. The CPG system is based on six coupled oscillators and complements the reactionary system to f...

In the previous lecture, we proved that if f is a permutation and B is an (S,)-hardcore predicate for f then G : x → f (x), B(x), which maps n bits to n + 1 bits, is (S,) pseudorandom. We then started investigating the performance of the iterative application of G, namely G (k) defined as in figure 1. B(x)) B(f(x))) B(f ((2)) (x))) B(f ((k-1)) (x))) f ((k)) (x)) xx GG GG GG GG Figure 1: Definit...

A new method of improving the properties of number sequences produced by a multiplicative congruential pseudorandom generator (MCPG) was proposed. The characteristic feature of the method is the simultaneous usage of numbers generated by the sawtooth chaotic map, realized in a finitestate machine, and symbols produced by the same map. The period of generated sequences can be significantly longe...

Cough is an important defensive reflex that eliminates particles and secretions from the airways and protects the lower airways from the aspiration of foreign materials. Although the classical cough center is thought to be situated in or around the nucleus tractus solitarius (NTS) of the brainstem, our understanding of its profile is still incomplete. Accumulating evidence suggests a new concep...

In this paper we investigate a biological framework to generate and adapt a motion pattern so that can be energy efficient. In fact, the motion pattern in legged animals and human emerges among interaction between a central pattern generator neural network called CPG and the musculoskeletal system. Here, we model this neuro - musculoskeletal system by means of a leg - like mechanical system cal...
