Humans and animals readily utilize active sensing, or the use of self-motion, to focus sensory and cognitive resources on the behaviorally most relevant stimuli and events in the environment. Understanding the computational basis of natural active sensing is important both for advancing brain sciences and for developing more powerful artificial systems. Recently, we proposed a goal-directed, co...

In this research, we focus on active sensing solutions to address challenging properties in complex environments, such as uncertainty, partial observability, non-stationarity, and limited resources. We describe our ongoing contributions, focusing on sensing for both individual agents and cooperating teams. We also outline how we are applying our research to two real-world applications: personal...

A system is described that integrates vision and tactile sensing in a robotics environment to perform object recognition tasks. It uses multiple sensor systems (active touch and passive stereo vision) to compute three dimensional primitives that can be matched against a model data base of complex curved surface objects containing holes and cavities. The low level sensing elements provide local ...

Structural control systems have shown the potential to effectively reduce the response of civil structures to a variety of loads including strong winds and earthquakes. However, current structural control systems necessitate the installation of a wired monitoring system to provide communication between a centralized controller and system sensors and actuators. As semi-active control systems con...

Vibrio fischeri possesses two quorum-sensing systems, ain and lux, using acyl homoserine lactones as signaling molecules. We have demonstrated previously that the ain system activates luminescence gene expression at lower cell densities than those required for lux system activation and that both systems are essential for persistent colonization of the squid host, Euprymna scolopes. Here, we ask...

despite of suitable geological and climatic conditions for forming and evolution of alluvial fans and importance of this landform as soil and water resources in arid regions, there are limited studies about this landform in iran. in the present study, evolution and pedogenic development of geomorphic surfaces of an alluvial fan in eastern isfahan were studied by using remote sensing, field and ...

We provide a broad review of approaches for developing chemosensor systems whose operating parameters can adapt in response to environmental changes or application needs. Adaptation may take place at the instrumentation level (e.g., tunable sensors) and at the data-analysis level (e.g., adaptive classifiers). We discuss several strategies that provide tunability at the device level: modulation ...

With the growing number of Wireless Sensor Network (WSN) monitoring systems in outdoor environments, smart sensing capability has attracted great research interests recently: scientists and researchers expect long-term healthy systems running in harsh environments. Because of the environmental damages to less-protected sensors, a sensing component, is highly desirable to be robust and faithful ...
