Fig. 1 Sensor Network Design System

We "propose a profile-based sensing framework for adaptive sensor systems based on models that relate possibly heterogeneous sensor data and profiles generated by the models to detect events. With these concepts, three phases for building the sensor systems are extracted from two examples: a combustion control sensor system for an automobile engine, and a sensor system for home security. The three phases are: modeling, profiling, and managing trade-offs. Designing and building a sensor system involves mapping the signals to a model to achieve a given mission."

Theme2:Biological Closure and Life System Theory

Fig. 2 Array System for Bio Dynamics

We discuss "a conjecture that entities of similar kinds behave similarly, and hence a collective of similar entities may be treated as one entity (a collective identity). We previously reported that this conjecture may be formalized as an additive symmetry exhibited by two or more similar species in the Lotka-Volterra model." We consider "a formalization based on the Stable Marriage Problem. That is, similar individuals exhibit the additive symmetry and may be treated as one collective entity (called “generalized individual”). This formalization allows us to relate the collectives with concepts such as decomposability and diversity based on the similarity and distinguishability."

Theme3:Intelligent Networked Systems

Fig. 3 Mutual Repairing in a Cluster of Cooperative Agents

We discuss "a critical phenomenon in a self-repair network by mutual copying. Extensive studies have been done on critical phenomena in many fields such as in epidemic theory and in percolation theory with an effort of identification of critical points. However, from the viewpoints of cleaning up a network by mutual copying, critical phenomena have not much studied. A critical phenomenon has been observed in a self-repair network. Self-repairing by mutual copying is “the double-edged sword” that could cause outbreaks with inappropriate parameters, and careful investigations are needed."
