Fast and Loose: Biologically Inspired Couplings
نویسندگان
چکیده
Recent years have seen the discovery of gaseous transmitters in biological nervous systems. An ANN inspired by such gaseous signalling, the GasNet, has previously been shown to be more evolvable than traditional ANNs. Here we present 2 new versions of the GasNet which take further inspiration from the properties of gaseous signalling. The plexus model is inspired by the cortical nNOS plexus and the properties of the NO signal it generates. The receptor model is inspired by the mediating action of neurotransmitter receptors. Both models are shown to significantly further improve evolvability. We describe preliminary results suggesting that the reasons for the increase in evolvability is the loose coupling of distinct signalling mechanisms. Issues surrounding the degree of coupling between these mechanisms, one ‘chemical’ and one ‘electrical’, are discussed.

A new four elements compact antenna array is presented and discussed to achieve enhanced phase resolution without sacrificing the array output power. This structure inspired by the Ormia Ochracea’s coupled ears. The analogy between this insect acute directional hearing capabilities and the electrically compact antenna array is used to enhance the array sensitivity to direction of arrival estima...
متن کاملEnhancing inter-organizational resilience by loose coupling concept and complexity paradigm
During a co-design project, we modeled formal and informal cooperation which are expressions of tight and loose couplings. Our findings confirm that loose couplings are crucial since they enable selforganization and emerging processes which often underlie success of codesign. We offer new insight into management and organization theories by presenting an inter-organizational resilience model wh...
متن کاملFlexible Couplings: Diffusing Neuromodulators and Adaptive Robotics
Recent years have seen the discovery of freely diffusing gaseous neurotransmitters, such as nitric oxide (NO), in biological nervous systems. A type of artificial neural network (ANN) inspired by such gaseous signaling, the GasNet, has previously been shown to be more evolvable than traditional ANNs when used as an artificial nervous system in an evolutionary robotics setting, where evolvabilit...
متن کاملDesign and Experiments of a Dragonfly-Inspired Robot
This paper describes the design of dragonfly-inspired robots. Dragonflies demonstrate unique and superior flight performances than most of the other insect species. They are equipped with two pairs of independently controlled wings. The high level of dexterity in wing motion of the dragonfly allows it to hover, fly fast forward, make turns rapidly, fly sideways, and even glide. A dragonfly-insp...
