Sum of Pseudoproducts (SPPs) are three-level network structures that give a good compromise between compact representation and small depth of the resulting circuit. In this paper the testability of circuits derived from SPPs is studied. For SPPs several restricted forms can be considered. While full testability can be proved for some classes, others are shown to contain redundancies. Experiment...

Directional switching in a self-propelled particle model with delayed interactions is investigated. It is shown that the average switching time is an increasing function of time delay. The presented results are applied to studying collective animal behavior. It is argued that self-propelled particle models with time delays can explain the state-dependent diffusion coefficient measured in experi...

According to the steering mode of self-propelled modular transporter, the key component of the steering system with electro-hydraulic proportional directional valve was designed. The model of the transporter steering single loop system was established through the method of power bond graph and was simulated. The dynamic characteristics of steering circuit were analyzed. Results indicate that th...
