Abstract. Lateral inhibition is described as an emergent property of the Delta-Notch signalling network. Two separate model representations of lateral inhibition are proposed for different purposes. One provides information about bioenergetics while the other has the capability to produce a physical representation. It is proposed that both can be used in further studies of the sensory pathways in the human connectome model of brain function.
Due to the increasing complexity of the system of systems within the aero-auto domains, architecture modelling and analysis is becoming progressively more important to systems engineering design. The drive from both domains is for more functionality and efficiency from vehicles. The resultant effect on system development means the complexity of the designs has increased and thus the complexity of the virtual simulations used for test and analysis has also increased. When actual systems or their components are integrated with the simulation environment, live-virtual testing places real-time demands on the testing of the architecture and environment. This paper describes a proposed innovative approach, derived from aerospace engineering, where the vehicle requirements are allocated to relations between the elements in the architecture and not just to system elements. An approach to using the relational oriented modelling structure for test and analysis is also described. The requirements and system architecture models specified using relational orientation are therefore seen to provide an early demonstration of a rigorous new approach to system of systems design, test and analysis that uses requirements traceability at the architecture level. This approach promises to bring better traceability of system requirements to the simulation of vehicle behaviour in general and to real time behaviour in particular.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
